2 |
|
|
3 |
< |
1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are |
4 |
< |
case sensitive |
3 |

< |
2. Single line SQL comments starting with '--' are now recognised by SQL Parser. |
6 |
> |
2. Update some examples to replace test for null date with the NullDate constant |
7 |
> |
instead of zero. This is because Laz 3.0 changes the value of NullDate. |

|
11 |
< |
4. FBMessages: removal of unused messages |
11 |
> |
1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error |
12 |
> |
with later versions of fpc - later than 3.2.2. |
13 |
|
|
14 |
< |
5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set. |
14 |
> |
2. IBUpdateSQL. update internal queries if parent dataset database changed. |
15 |
|
|
16 |
< |
6. TIBSQLStatementType: SQLSavePoint added to end of enumeration. |
16 |

4. IBBufferedCursors: avoid range error when max field no. is > fields.count |
19 |
|
|
20 |
< |
1. Fix a problem with the SQL parameter parser that failed to recognise parameters |
25 |
< |
where the second character of the parameter name is a numeric. |
20 |
> |
5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count |
21 |
|
|
22 |
< |
2. New method for IAttachment: procedure getFBVersion(version: TStrings); |
28 |
< |
This returns the isc_version connection information as one or more lines. |
29 |
< |
This is the same information as returned by isql with the -z option. |

3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API |
32 |
< |
is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a |
33 |
< |
compiler option then the Firebird 3 API is no longer compiled in. |
24 |
> |
1. Maintenance update of 2.6.0. This version is still at beta. |
25 |
|
|
26 |
< |
4. IColumnMetaData: new method. |
26 |
> |
2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid. |

TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP} |
30 |
< |
dfDateTime, {SQL DATETIME} |
39 |
< |
dfTime); |
29 |

33 |
|
|
34 |
< |
This returns the max. number of characters returned by the "AsString" method |
35 |
< |
when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME. |
34 |

NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED |
35 |
> |
AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT |
36 |
> |
BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY |
37 |

ISSUES TO support@mwasoftware.co.uk |
38 |
|
|
39 |
< |
5. Additional argument for IAttachment.PrepareWithNamedParameters - |
40 |
< |
CaseSensitiveParams: boolean = false |
39 |
> |
1. Complete rewrite of internal buffer management in order to improve performance |
40 |
> |
and maintainability. Highlights: |
41 |
|
|
42 |
< |
If this argument is set to true then SQL parameter names are assumed to be case |
43 |
< |
sensitive and must be referenced (using ISQLParams.ByName) using the case |
44 |
< |
sensitive name. |
42 |
> |
* Extending the size of the buffer pool no longer has to copy the entire record |
43 |
> |
cache. Instead, a new extent is simply added to the buffer pool. |
44 |
> |
* A memory to memory copy of each display buffer now is avoided when scolling the |
45 |
> |
dataset. |
46 |
> |
* A separate set of buffers is now used for calculated fields. This avoids |
47 |
> |
having to keep copies of calculated field values in the buffer cache. |
48 |
> |
* Compact bitmaps are used to record null status and need to refresh in each |
49 |
> |
buffer. |
50 |
> |
* Display buffer type changed from PChar to TRecordBuffer in line with change of |
51 |
> |
buffer type in FCL-DB. |
52 |
|
|
53 |
< |
6. Bug fix: when setting a query parameter, it is now possible, when the parameter |
54 |
< |
is of type VarChar or Char to set the parameter to a numeric value (e.g. using |
55 |
< |
.AsCurrency) and then subsequently to update the value to a non-numeric string |
56 |
< |
using .AsString. |
53 |
> |
2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is |
54 |
> |
to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure. |
55 |
|
|
56 |
+ |
3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported. |
57 |
+ |
If either or both of these flags are set at design time (using the fields editor) |
58 |
+ |
then this forces a row refresh on respectively insert or update, or both, when the |
59 |
+ |
corresponding field is not present in an SQL RETURNING clause. |
60 |
|
|
61 |
+ |
4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve |
62 |
+ |
maintainability and readability and to add identification of primary key fields. |
63 |
|
|
64 |

FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000 |
64 |
> |
5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method |
65 |
> |
as a refresh of the current row. However, this is different behaviour to that described |
66 |
> |
in the FPC documentation for TDataset.Refresh which is described as "refetches the data in |
67 |
> |
the dataset from the underlying database, and attempts to reposition the cursor on |
68 |
> |
the same record as it was". IBX now complies with the FPC definition of Refresh. |
69 |
|
|
70 |
< |
1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary |
70 |
> |
6. A progammatic Row Refresh should no longer be required. |
71 |
> |
Use Insert/Update... returning to refresh any fields that may change following an |
72 |
> |
insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields |
73 |
> |
on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag |
74 |
> |
for the field at Design Time to force a row refresh if not in the returning clause. |
75 |
|
|
76 |
< |
2. Restrict IsMultiThread check to Unix only for compatibility with |
65 |
< |
https://bugs.freepascal.org/view.php?id=30535 |
76 |
> |
7. It should now be possible to insert a row into an empty unidirectional dataset. |
77 |
|
|
78 |
< |
3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with |
79 |
< |
named parameters and is intended to avoid problems with (e.g.) Execute Block |
80 |
< |
and processing internal parameters as statement parameters. |
78 |
> |
8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50). |
79 |
> |
This gives the number of buffers in the initial block for the buffer pool in |
80 |
> |
bi-directional datasets. BufferChunks (default 1000) gives the number of buffers |
81 |
> |
in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations |
82 |
> |
for small datasets. |
83 |
|
|
84 |
< |
4. New interface IFirebirdLibrary provides access to the underlying firebird DLL |
72 |
< |
or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI. |
84 |
> |

86 |
< |
5. New function added to IB.pas |
86 |
> |
1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead. |
87 |
|
|
88 |
< |
function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary |
88 |
> |
2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0 |
89 |
|
|
90 |
< |
This allows a Firebird Library to be loaded from an explicit path. use the |
79 |
< |
IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using |
80 |
< |
the library. It is possible to load Firebird libraries from different locations |
81 |
< |
simultaneously, each with a distinct IFirebirdAPI. |
90 |
> |
3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0 |

93 |
|
|
94 |
< |
1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when |
95 |
< |
program compiled with -CR command line switch. |
94 |
> |
1. TIBTransaction: new properties |
95 |
> |
property TransactionID: integer read GetTransactionID; |
96 |
> |
property IsReadOnly: boolean read GetIsReadOnly; |
97 |
> |
{published} |
98 |
> |
property TransactionName: string read FTransactionName write SetTransactionName; |
99 |
|
|
100 |
< |
2. IServiceManager additions (informational): |
101 |
< |
function getProtocol: TProtocol; |
102 |
< |
function getPortNo: AnsiString; |
100 |
> |
2. IBCustomDataset: per row blob and array buffer cached clear before processing |
101 |
> |
Insert or Update...Returning. This allows blobs and arrays to be returned |
102 |
> |
by the statement. |
103 |
|
|
104 |
< |
3. IServiceManager improved error handling. Interfaces changed: |
93 |
< |
function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean; |
94 |
< |
function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; |
95 |
< |
function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; |
104 |
> |
3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils. |
105 |
|
|
106 |
< |
4. IAttachment addition (informational) |
98 |
< |
function GetSecurityDatabase: AnsiString; |
106 |
> |
4. TransactionName initialised to a newly generated GUID if empty. |
107 |
|
|
108 |
< |
5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics |
109 |
< |
thus now returns accumulated stats for a select statement from opening a cursor |
110 |
< |
up to the last fetch. |
108 |
> |
5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper |
109 |
> |
for the fbintf package's journaling capability. TIBJournal is used to set the |
110 |
> |
file path and filename for the journal file and to Enabled (start journaling) and |
111 |
> |
disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for |
112 |
> |
more information, and comments in IBJournal.pas. |
113 |
|
|
114 |
< |
6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting |
105 |
< |
the problem. |
114 |
> |
6. TIBDatabase.InternalTransaction is now a read only transaction. |
115 |
|
|
116 |
< |
7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64" |
117 |
< |
replaces deprecated "comp" type. |
116 |
> |
7. Bug fix: blob id no longer set to null on update when blob has not been |
117 |
> |
retrieved. |
118 |
|
|
119 |
< |
10. Testsuite Test10 updated to include thread synchronisation for event reporting. |
119 |
> |
8. Row auto refreshed on update/insert if blob or array field updated and field |
120 |
> |
not in a returning clause. |
121 |
|
|
122 |
< |
11. URL Connection Strings: inet4 and inet6 now recognised. |
122 |
> |
9. ColumnCount moved from record buffer header to a single per dataset count. Reduces |
123 |
> |
buffer overhead and avoids problem when refresh query has a different column |
124 |
> |
count to select query i.e. incorrectly changing number of columns. |
125 |
|
|
126 |
< |
12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax. |
126 |
> |
10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations. |
127 |
|
|
128 |
< |
13. IAttachment.CharSetName2CharSetID is now performed case insensitive. |
128 |
> |
11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version |
129 |
> |
string. Note that the Version property returns an InterBase compatible version string. |
130 |
|
|
131 |
+ |
12. IBExtract: ensure sql identifiers returned as a LIST are always quoted. |
132 |

135 |
< |
1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character. |
135 |
> |
1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true. |
136 |
> |
This is for compatibility with Firebird 5 where Update...Returning can return |
137 |
> |
a cursor. |
138 |
|
|
139 |
< |
2. IAttachment: add two new methods |
124 |
< |
function HasDefaultCharSet: boolean; |
125 |
< |
function GetDefaultCharSetID: integer; |
139 |
> |

140 |
|
|
141 |
< |
These return, respectively, true if a connection default character set was |
142 |
< |
specified and the character set id of the connection default character set. |
143 |
< |
The DefaultCharSetID is cached when the connection is opened and hence does not |
130 |
< |
require a database lookup. |
141 |
> |
1. Add try-..except check when initially loading library in IDE. This should |
142 |
> |
ensure that IDE continues to load even when a failure occurs in IBX load |
143 |
> |
library. |
144 |
|
|
145 |
< |
3. Avoid exception when a text blob is a stored procedure parameter. |
145 |
> |
2. IBXScript: now recognises a CASE...END block within a stored procedure and |
146 |
> |
hence will correctly detect end of the outer containing block when the block |
147 |
> |
contains a SELECT ... CASE ... END construct. |
148 |
|
|
149 |
< |
4. Update test suite to include a test for a stored proc returning a text blob. |
149 |
> |
3. IBExtract: some further tidying up to remove extraneous white space. |
150 |
|
|
151 |
< |
5. IAttachment: add |
152 |
< |
function GetRemoteProtocol: AnsiString; |
138 |
< |
function GetODSMajorVersion: integer; |
139 |
< |
function GetODSMinorVersion: integer; |
140 |
< |
function GetAuthenticationMethod: AnsiString; |
151 |
> |
4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time |
152 |
> |
errors when extra elements are added to DB.TFieldType. |
153 |
|
|
154 |
< |
These results are cached when the connection is opened and hence do not |
143 |
< |
require a database lookup. |
154 |
> |
5. IBUpdate: updated to reflect changes to ISQLParam. |
155 |
|
|
156 |
< |
6. IAttachment: add "function GetConnectString: AnsiString;" This returns the |
146 |
< |
connect string used to create/connect to the database. |
156 |
> |
6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string. |
157 |
|
|
158 |
< |
7. IAttachment: Create Database using SQL statement. The username and password |
149 |
< |
are now extracted and used to populate a DPB made available via IAttachment.getDPB. |
150 |
< |
It is now possible to use IAttachment disconnect/connect to reconnect to |
151 |
< |
a database for which the initial connection was established by a create |
152 |
< |
database sql statement. Available in FPC only. |
158 |
> |
7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement. |
159 |
|
|
160 |
< |
8. Update Test 1 to test 5, 6 and 7 above. |
160 |
> |
8. IBSQL: Support for scrollable cursors added (note: local databases only) |
161 |
|
|
162 |
< |
9. IBUtils code tidy up. |
162 |
> |

|
|
164 |
< |
10. Parameter Block interfaces "find" method. As documented, this should have |
165 |
< |
returned a nil interface when the item could not be found. Instead, an empty |
160 |
< |
interface item was returned. "Find" now works as documented and will return |
161 |
< |
a nil interface if the item cannot be found. |
164 |
> |
1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the |
165 |
> |
exception of those defined to be one byte wide e.g. DBImplementationNo. |
166 |
|
|
167 |
< |
11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date. |
167 |
> |
2. TIBSQL: Batch Update/Insert support added. |
168 |
|
|
169 |
< |
12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information |
170 |
< |
requests with additional parameters. This is to enable support for fb_info_page_contents |
171 |
< |
(return of page contents). Response to fb_info_page_contents returned as |
172 |
< |
a string with code page CP_NONE. |
169 |
> |
3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property |
170 |
> |
is no longer automatically converted to upper case when it is syntactically a |
171 |
> |
SQL Identifier. This is to support the use of stored procedures defined e.g. |
172 |
> |
as CREATE PROCEDURE "iCASE". |
173 |
|
|
174 |
< |
13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus |
175 |
< |
test suite updated. |
174 |
> |
There could be a backwards compatibility issue when the StoredProcName was entered |
175 |
> |
manually at design time. That is not selected from the drop down list. If the |
176 |
> |
StoredProcName is entered in mixed case and the procedure was declared e.g. as |
177 |
> |
CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should |
178 |
> |
ensure that the value of the StoredProcName is all upper case, unless it was |
179 |
> |
declared under dialect 3 and explicitly as mixed case (i.e. delimited by double |
180 |
> |
quotes). |
181 |
|
|
182 |
< |
14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as |
183 |
< |
a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type. |
182 |
> |
Note that when a stored procedure name was declared delimited in double quotes, |
183 |
> |
as in the first example above, the value of the StoredProcName property must not |
184 |
> |
include the delimiters (double quotes). |
185 |
|
|
186 |
< |
15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet. |
187 |
< |
An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non |
178 |
< |
default connection port to be specified. |
186 |
> |
4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in |

5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to |
190 |
> |
'Version.%.3d' and is used to generate the section header names (for a given |
191 |
> |
version no.) in the upgrade.conf file. |
192 |
|
|
193 |
< |
1. Fix issues with setting SQL Param values using SetAsString with Numeric types. |
183 |
< |
Scale is no longer ignored. |

IBX Change Log version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100 |
194 |
|
|
195 |
< |
2. Fix issues with setting SQL Param values using SetAsString with Date values |
196 |
< |
not in locale format but which are recognised by Firebird. Date values that |
187 |
< |
cannot be converted to a string using Pascal library are now passed through |
188 |
< |
to Firebird as Text Strings. |
195 |
> |
1. -c command line option added to fbsql example program. Used to set connection |
196 |
> |
character set. |
197 |
|
|
198 |
< |
3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns |
191 |
< |
UTF8 and not UNICODE_FSS. |

199 |
|
|
200 |
< |
4. Charset ID problem. When using Firebird 3, with no default database character set |
194 |
< |
and a column has a non-default collation specified, an incorrect character set |
195 |
< |
id was being reported that could result in a 'division by zero' error when |
196 |
< |
used by IBX. This has now been fixed. |
200 |
> |
1. Firebird 4 support added. |
201 |
|
|
202 |
< |
5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID, |
203 |
< |
CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as |
200 |
< |
the character sets supported can be updated on a per database basis. That is |
201 |
< |
it is possible to add a (Firebird) user defined character set to a database. |
202 |
> |
2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and |
203 |
> |
extended precision NUMERIC fields are supported. |
204 |
|
|
205 |
< |
6. Add RegisterCharSet to IAttachment. This is used to register a user defined character |
204 |
< |
set supported by Firebird with the API. |
205 |
> |
3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields. |
206 |
|
|
207 |
< |
7. Add missing isc_info_db_read_only to list of decoded Database Information items |
208 |
< |
in FBOutputBlock.pas and update test suite to include this item. |
207 |
> |
4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE |
208 |
> |
and TIME WITH TIME ZONE fields. These inherit from TDateTimeField. |
209 |
|
|
210 |
< |
8. FB30Client: avoid always using "StartMultiple" when only a single database attachment. |
210 |
> |
5. IBExtract now supports FB4 enhancements: |
211 |
> |
- new data types as above |
212 |
> |
- Identity column extensions |
213 |
> |
- Default user role |
214 |
> |
- SQL Security clause for Database, Tables, Procedures, Functions and Triggers |
215 |
> |
- Internal Functions |
216 |
|
|
217 |
< |
9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client |
212 |
< |
library or finding it by disk location, the PATH environment variable is now also set to |
213 |
< |
include the FIREBIRD directory. This is to ensure that the correct dlls in the |
214 |
< |
firebird client library dependencies are loaded. |
217 |
> |
6. IBExtract: new event: OnExtractLines. |
218 |
|
|
219 |
< |
10. Testsuite: Ensure consistent UTF-8 output on Windows console. |
219 |
> |
7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145 |
220 |
|
|
221 |
< |
11. Testsuite: Update Windows script to include FPC 3.0.4 in search path. |
221 |
> |
8. IBXServices: Server version no. parsing now allows any letter before major version number |
222 |
> |
and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1" |
223 |
|
|
224 |
< |
12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer |
224 |
> |
9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default |
225 |
> |
format for rendering a time zone. |
226 |
|
|
227 |
< |
13. FB30Statement: A check has been added to ensure that all SQL Parameters |
228 |
< |
have been given a value (including NULL). Previously, failing to set the |
224 |
< |
value of an SQL Parameter could give rise to unpredictable results or |
225 |
< |
an SQLDA error. |
227 |
> |
10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date |
228 |
> |
to convert TIME WITH TIME ZONE data type values to and from GMT. |
229 |
|
|
230 |
< |
14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set. |
230 |
> |
11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to |
231 |
> |
IIBGUIInterface and IIBTimerInf respectively. |
232 |
|
|
233 |
< |
15. FBAttachment: Avoid string reference count error when processing an Ansistring |
234 |
< |
parameter in an array of const passed to IAttachment.OpenCursor, etc. |
233 |
> |
12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames |
234 |
> |
now accessible as properties of TIBDatabase and TIBTransaction respectively. |
235 |
|
|
236 |
< |
16. FBAttachment: Allow for WideString and UnicodeString parameters in an array |
237 |
< |
of const passed to IAttachment.OpenCursor, etc. |
236 |
> |
13. String Fields: when a fixed character with (CHAR) field is returned, it is now |
237 |
> |
truncated to its fixed character width rather than being right padded with |
238 |
> |
white space to the maximum data size. |
239 |
|
|
240 |
+ |
14. TIBTable.Empty table. In additional to deleting all records in the underlying |
241 |
+ |
table, the internal buffers are now also flushed ensuring that the TIBTable is |
242 |
+ |
also empty. |

15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset. |
245 |
|
|
246 |
< |
1. Change syntax to Mode Delphi |
246 |
> |
16. TIBXControlService descendents: DatabaseName may now be set using a database |
247 |
> |
connect string. The database name is extracted from the connect string. |
248 |
|
|
249 |
< |
2. Change all uses of string type to explicit AnsiString in order to ensure |
241 |
< |
compatibility between Delphi and FPC. |
249 |
> |
17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel |
250 |
|
|
251 |
< |
3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs |
244 |
< |
defined for each interface. |
251 |
> |
18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL. |
252 |
|
|
253 |
< |
4. Generics syntax variations for Delphi added |
253 |
> |
19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password |
254 |
> |
not being present as required. |
255 |
|
|
256 |
< |
5. PChar replaced with PByte expect where an actual string is being referenced, |
257 |
< |
where PAnsiChar is used instead. |
256 |
> |
20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent |
257 |
> |
version that can be customised to work with other database drivers. |
258 |
|
|
259 |
< |
6. Review of type definitions in IBExternals to ensure Delphi compatibility |
259 |
> |
21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids |
260 |
> |
unnecessary CR at end of line on Unix platforms. |
261 |
|
|
262 |
< |
7. Testsuite updated for Delphi |
262 |
> |
22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10 |
263 |
> |
seconds in order to reduce risk of message loss. |
264 |
|
|
265 |
< |

23. ISQLMonitor: read and write count statistics now available via: |
266 |
> |
property TIBSQLMonitor.ReadCount; |
267 |
> |
IIBSQLMonitorHook.GetWriteCount: integer; |
268 |
|
|
269 |
< |
1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with |
258 |
< |
large blobs and the FB3 API. |
269 |
> |
24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC. |
270 |
|
|
271 |
< |
2. Update Event Handling algorithm to avoid looping due to recreation of the |
261 |
< |
event block. |
271 |
> |
IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100 |
272 |
|
|
273 |
< |
3. Avoid invalid XSQLDA error when the only parameter is updated to null |
273 |
> |
1. TIBStringField: when a string value is read from a dataset buffer, if the |
274 |
> |
number of UTF8 characters exceeds the string size then string is truncated |
275 |
> |
to the maximum string size. This is usually a problem with fixed width columns |
276 |
> |
right padded with white space. |
277 |
|
|
278 |
< |
4. Array Handling: fix problem with text arrays with character set none. When the |
279 |
< |
DB connection has a default character set (e.g. UTF8), an error is raised by |
280 |
< |
Firebird if the space allocated is not enough to allow for transliteration, even |
281 |
< |
though it is not required for character set none. |
278 |
> |
2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset. |
279 |
> |
If SQLFiltered is set then when a dataset is opened, each line in the |
280 |
> |
SQLFilterParams property is assumed to be a SQL condition clause and |
281 |
> |
ANDed into the Where clause of the SQL Select statement provided as a |
282 |
> |
dataset property. Each such SQL condition thus acts as an additional filter |
283 |
> |
on the dataset. |
284 |
|
|
285 |
< |
5. IBUtils: List of reserved words brought up-to-date |
285 |
> |
3. The Filtered property inherited from TDataset is no longer used for SQL (server |
286 |
> |
side filters). |
287 |
|
|
288 |
< |
6. Add ISQL style performance statistics collection to IStatement |
288 |
> |
4. IBLookupComboEditBox: Selection should no longer reset to start of text when |
289 |
> |
text matches complete entry. |
290 |
|
|
291 |
< |
7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided |
292 |
< |
CREATE DATABASE statement. |
291 |
> |
5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail |
292 |
> |
dataset are active (avoids risk of access violation if master is inactive) |
293 |
|
|
294 |
< |
8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in |
278 |
< |
an array dimension is not mistaken for a named parameter prefix. |
294 |
> |
6. TIBEvents: Registered property can now be set at design time even if database not open |
295 |
|
|
296 |
< |
9. Trim function no longer applied to result of GetAsString for SQL_TEXT |
297 |
< |
when Character set is octets. Avoids loss of non printable characters at start of string. |
296 |
> |
7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents. |
297 |
> |
This should prevent "spillover" of events between sessions. |
298 |
|
|
299 |
< |
10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance |
300 |
< |
statistics for the last action. Requires use of procedure IStatement.EnableStatistics |
301 |
< |
to enable stats gathering. |
299 |
> |
8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset. |
300 |
> |
This should ensure that the internal buffer is set up correctly and avoids |
301 |
> |
a duplicate initial row. |
302 |
|
|
303 |
< |
11. API Version information added as constants to IB.pas |
303 |
> |
9. TIBStringField: DataSize now given as byte size of string less trailing any zero character. |
304 |
> |
That is, the DataSize should be the field size * character set width. The |
305 |
> |
value returned by DataSize is now the same as the Dataset buffer size reserved |
306 |
> |
for the field. |
307 |
|
|
308 |
< |
12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID |
308 |
> |
10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes. |
309 |
|
|
310 |
< |
13. Firebird Character set "NONE" now interpreted as codepage CP_ACP. |
310 |
> |
11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer |
311 |
> |
and vice-versa. This may result in an exception being raised (correctly) for |
312 |
> |
older programs when using dataset fields added to a form and the database has been |
313 |
> |
upgraded. For example, computed fields can change from 32-bit to 64-bit integers. |
314 |
> |
In such cases, the field needs to be deleted in the IDE fields editor and then |
315 |
> |
added back in. |

320 |
< |
1. Initial Release |
320 |
> |
12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This |
321 |
> |
should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit |
322 |
> |
is cancelled. |
323 |
|
|
324 |
+ |
13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if |
325 |
+ |
called on a null field. |
326 |
+ |
|
327 |
+ |
14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates |
328 |
+ |
results in an empty dataTC86 Client side Filtered Dataset 1 X |
329 |
+ |
set. |
330 |
+ |
|
331 |
+ |
15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when |
332 |
+ |
a cached update is applied and an exception is raised. |
333 |
+ |
|
334 |
+ |
16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer. |
335 |
+ |
|
336 |
+ |
17. Console Mode Local Database support: backup/restore should now work correctly. |
337 |
+ |
|
338 |
+ |
18. Local Database Support: if an upgrade fails, a downgrade is now performed if |
339 |
+ |
possible and an exception raised. |
340 |
+ |
|
341 |
+ |
19. MinimumVersionNo added to Local Database Support. Database will not open if |
342 |
+ |
below this version no. and upgrade not possible. |

345 |
+ |
|
346 |
+ |
1. TIBXDataSet and Generators: Generator Names that are not all upper case or |
347 |
+ |
not SQL Identifiers are now supported. |
348 |
+ |
|
349 |
+ |
2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is |
350 |
+ |
passed to the Firebird engine for execution. |
351 |
+ |
|
352 |
+ |
3. TIBDataSet: Unidirectional datasets now give an error message if an attempt |
353 |
+ |
is made to scroll back. |
354 |
+ |
|
355 |
+ |
4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf |
356 |
+ |
|
357 |
+ |
5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now |
358 |
+ |
only enclosed in double quotes in SQL dialect 3 and when it needs to be. |
359 |
+ |
|
360 |
+ |
6. TIBLookupComboEditBox: when the list source opens, the ListField name is now |
361 |
+ |
validated. If no match is found in the list of field names and the database has |
362 |
+ |
been opened in SQL Dialect 3, then the ListField Name is converted to upper case |
363 |
+ |
if it then matches a field name. Otherwise, a Listfield not valid exception occurs. |
364 |
+ |
|
365 |
+ |
7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance |
366 |
+ |
with fpc 3.2. |
367 |
+ |
|
368 |
+ |
IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000 |
369 |
+ |
|
370 |
+ |
|
371 |
+ |
1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides" |
372 |
+ |
and is used to override the default settings in the client side "firebird.conf" This |
373 |
+ |
includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings". |
374 |
+ |
Each line of the string list should be a setting in the same format as "firebird.conf". |
375 |
+ |
For example "WireCompression = true" in order to request wire compression on the client side. |
376 |
+ |
|
377 |
+ |
Note: explicit settings in the client side "firebird.conf" appear to take precedence |
378 |
+ |
over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings |
379 |
+ |
also require a compatible setting in the server side "firebird.conf". For example |
380 |
+ |
"WireCompression = true" must also be set in the server's "firebird.conf" for wire |
381 |
+ |
compression to be used. |
382 |
+ |
|
383 |
+ |
Whether or not WireCompression or WireCrypt are in use can be checked using the information |
384 |
+ |
returned with the Client/Server protocol version. See ibx/examples/dbadmin and |
385 |
+ |
ibx/examples/dbinfo for examples of how to display this information. |
386 |
+ |
|
387 |
+ |
2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This |
388 |
+ |
is a "convenience" property. If set the "WireCompression=true" is added to the |
389 |
+ |
ConfigOverrides. If unchecked then this setting is removed. |
390 |
+ |
|
391 |
+ |
3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and |
392 |
+ |
not "INT64". |
393 |
+ |
|
394 |
+ |
4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut |
395 |
+ |
These are: |
396 |
+ |
property TimestampFormat: string; |
397 |
+ |
property DateFormat: string; |
398 |
+ |
property TimeFormat: string; |
399 |
+ |
|
400 |
+ |
Respectively, these provide the date time format templates for SQL types: TIMESTAMP, |
401 |
+ |
DATETIME and TIME. The format strings use the standard FPC date/time format |
402 |
+ |
characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html). |
403 |
+ |
|
404 |
+ |
If any of the above properties are set to an empty string, then the locale default |
405 |
+ |
is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the |
406 |
+ |
locale default is extended by appending '.zzz' to include milliseconds. |
407 |
+ |
|
408 |
+ |
TIBCSVDataOut by default sets these properties to the empty string, while the other |
409 |
+ |
two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively. |
410 |
+ |
|
411 |
+ |
5. New published property for TIBCSVDataOut: |
412 |
+ |
property QuoteStrings: boolean (default true) |
413 |
+ |
|
414 |
+ |
If false then strings are unquoted, otherwise, the QuoteChar property value is |
415 |
+ |
used to delimit each and every string in the output. |
416 |
+ |
|
417 |
+ |
6. New published properties for TIBCSVDataOut: |
418 |
+ |
property FieldSeparator: string; |
419 |
+ |
property HeaderSeparator: string; |
420 |
+ |
|
421 |
+ |
Respectively, these provide the separator character(s) used to separate fields |
422 |
+ |
in data and header rows. Both default to ','. |
423 |
+ |
|
424 |
+ |
7. New published properties for TIBCSVDataOut and TIBBlockFormatOut: |
425 |
+ |
TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object; |
426 |
+ |
property OnFormatTextString; |
427 |
+ |
|
428 |
+ |
This event handler can be used to process text strings before they are included |
429 |
+ |
in the output e.g. to replace unprintable characters with alternative strings. |
430 |
+ |
This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT. |
431 |
+ |
|
432 |
+ |
8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name. |
433 |
+ |
Uses "FindParam" if in order to find out if a parameter with a given name exists |
434 |
+ |
and without raising and exception if it does not. |
435 |
+ |
|
436 |
+ |
9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure |
437 |
+ |
consistency with SQL queries. |
438 |
+ |
|
439 |
+ |
10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery. |
440 |
+ |
When true, SQL statement parameter names are parsed case sensitive. Note for |
441 |
+ |
TIBDataSet only applies to Select query. |
442 |
+ |
|
443 |
+ |
11. IBEvents: removing a TIBEvent component from a form should no longer result in |
444 |
+ |
an IDE exception. |
445 |
+ |
|
446 |
+ |
12. LocalDBSupport: initial database creation should now work correctly |
447 |
+ |
when the schema source is an sql file. |
448 |
+ |
|
449 |
+ |
13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent" |
450 |
+ |
when defined, this handler will be called by the internal TIBXScript during |
451 |
+ |
initial database creation when the schema source is an sql file and may be used |
452 |
+ |
to provide a visual indication of progress in console mode. |
453 |
+ |
|
454 |
+ |
14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set |
455 |
+ |
to true while a new local database is being created and its schema populated. |
456 |
+ |
Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions |
457 |
+ |
when the database is disconnected/connected during the create DB procedure. |
458 |
+ |
|
459 |
+ |
15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement |
460 |
+ |
are now always ignored and replaced by the user name and password provided as |
461 |
+ |
the login parameters for the TIBDatabase referenced from the TIBXScript. The |
462 |
+ |
IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is |
463 |
+ |
completely ignored if this property is true. |
464 |
+ |
|
465 |
+ |
16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes |
466 |
+ |
to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise |
467 |
+ |
ImageIndex and SelectImageIndex values on AddNode. |
468 |
+ |
|
469 |
+ |
17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now |
470 |
+ |
read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share |
471 |
+ |
the same database connection. |
472 |
+ |
|
473 |
+ |
18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property. |
474 |
+ |
if provided, this should be an conditional SQL expression suitable for |
475 |
+ |
including in an SQL Select statement "where" clause. If non-empty and the |
476 |
+ |
"Filtered" property is true then the SQL expression provided as the value of |
477 |
+ |
the "Filter" property is "ANDed" with any existing condition statement |
478 |
+ |
in the SQL statement's "Where" clause. |
479 |
+ |
|
480 |
+ |
If the "Filter" property is set at run time, the "Filtered" property is true |
481 |
+ |
and the dataset is already open, then the dataset is closed and re-opened automatically. |
482 |
+ |
|
483 |
+ |
The "Filter" condition may include IBX style parameters. In which case, their |
484 |
+ |
value must be set by the dataset's "OnBeforeOpen" event handler. |
485 |
+ |
|
486 |
+ |
This is a public property for TIBDataSet and TIBQuery query and intended for |
487 |
+ |
use at run time. |
488 |
+ |
|
489 |
+ |
Note: The property is a published property of TIBTable. The TIBTable functionality |
490 |
+ |
is unaffected by this change. |
491 |
+ |

+ |
IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000 |
493 |
+ |
|
494 |
+ |
1. Remove need to check for IsMultiThread by providing access to GUI timers via |
495 |
+ |
IBGUIInterface. Note: master/detail delay timer does not apply to console |
496 |
+ |
mode apps. |
497 |
+ |
|
498 |
+ |
2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select |
499 |
+ |
statement. This avoids problems if "Execute Block" is used as the Query. |
500 |
+ |
|
501 |
+ |
3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the |
502 |
+ |
internal SQL tokeniser routines. |
503 |
+ |
|
504 |
+ |
4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse |
505 |
+ |
as a select statement, with or without CTEs. |
506 |
+ |
|
507 |
+ |
5. IBSQLParser: parser now recognises the "ROWS" clause. |
508 |
+ |
|
509 |
+ |
6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the |
510 |
+ |
internal SQL tokeniser routines. |
511 |
+ |
|
512 |
+ |
7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions |
513 |
+ |
being raised for valid set statements processed by a data formatter. |
514 |
+ |
|
515 |
+ |
8. New published property for TIBDatabase and TIBXServicesConnection. This is |
516 |
+ |
FirebirdLibraryPathName: string. If not empty it is used to explicitly specify |
517 |
+ |
the path of the Firebird Library used by the database/services connection. |
518 |
+ |
|
519 |
+ |
9. New read only public property for TIBDatabase and TIBXServicesConnection. This |
520 |
+ |
is FirebirdAPI and returns the IFirebirdAPI interface used by the database/ |
521 |
+ |
services connection. |
522 |
+ |
|
523 |
+ |
10.SQL Property editors now quote parameter names if "Quote identifier" is selected |
524 |
+ |
or param name is not a valid SQL identifier. |
525 |
+ |
|
526 |
+ |
11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive |
527 |
+ |
view of whether the text box should be editable when no DataSource is specified. |
528 |
+ |
TIBLookupComboEditBox has been updated to workaround this problem. As long as |
529 |
+ |
ReadOnly is false, the text box is editable when no DataSource is specified. |
530 |
+ |
|
531 |
+ |
12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of |
532 |
+ |
the FBLIB environment variable. If you do not want to permit this then you |
533 |
+ |
must modify the Register procedure in the design/IBDBReg.pas unit to remove |
534 |
+ |
this setting. |
535 |
+ |
|
536 |
+ |
IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100 |
537 |
+ |
|
538 |
+ |
1. IBCustomDataset: replace deprecated function ValidUTF8String with call to |
539 |
+ |
Utf8EscapeControlChars |
540 |
+ |
|
541 |
+ |
IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100 |
542 |
+ |
|
543 |
+ |
IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove |
544 |
+ |
all previous copies of the IBX source code tree before installing this release. |
545 |
+ |
|
546 |
+ |
The IBX packages used by most users have not changed, with one exception. The |
547 |
+ |
IBServices unit has been moved to the package iblegacyServices.lpk. To continue |
548 |
+ |
to use the IBServices unit in your applications, please add the iblegacyServices |
549 |
+ |
to the list of dependencies. To do this, open the Project Inspector and select |
550 |
+ |
Add->New Requirement and select "ibLegacyServices" from the list of available |
551 |
+ |
packages. |
552 |
+ |
|
553 |
+ |
1. New unit IBXServices. The IBXServices unit is a re-architectured update of |
554 |
+ |
the IBServices unit providing what is intended to be a clearer and easier to |
555 |
+ |
use set of IB Services components. See Chapter 10 of the IBX User Guide for |
556 |
+ |
more information and the guide to "Firebird Service Management Using IBX". |
557 |
+ |
As indicated above, the legacy services components are still available and |
558 |
+ |
provided in a separate package. There is no need to update working applications |
559 |
+ |
using the older versions except for an additional package dependency. |
560 |
+ |
|
561 |
+ |
2. The IBX packages and source code tree have been re-organised in an attempt to |
562 |
+ |
finally get rid of the "duplicate ppu" warnings. This re-organisation should |
563 |
+ |
not affect existing users. Section 2.3 of the IBX User Guide describes the |
564 |
+ |
new set of IBX packages. |
565 |
+ |
|
566 |
+ |
3. The ibx/examples/DBAdmin and the ibx/examples/services example have been |
567 |
+ |
updated to use the new Services API components. |
568 |
+ |
|
569 |
+ |
4. The iblocal package has been updated to use the new Services API components. |
570 |
+ |
|
571 |
+ |
5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of |
572 |
+ |
TIBXSecurityService. It had been wrongly classified in the previous version |
573 |
+ |
as a per database configuration item. It is global to a server and hence |
574 |
+ |
correctly positioned as part of the Security Package. In the DBAdmin example, |
575 |
+ |
the setting has moved to the mappings page. |
576 |
+ |
|
577 |
+ |
6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements |
578 |
+ |
are ignored. |
579 |
+ |
|
580 |
+ |
7. TIBDatabase: DropDatabase now ensures that all transactions have been properly |
581 |
+ |
closed before the database is dropped. Before and After Disconnect event handlers |
582 |
+ |
are also fired. |
583 |
+ |
|
584 |
+ |
8. TIBTransaction: OnStartTransaction event now fires every time the transaction |
585 |
+ |
is started and not just the first time. |
586 |
+ |
|
587 |
+ |
9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform |
588 |
+ |
depenendency with comp type. |
589 |
+ |
|
590 |
+ |
10. IBDataOutput: select query data output is now sent to stdout instead of stderr. |
591 |
+ |
|
592 |
+ |
11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName |
593 |
+ |
then this is recognised and not ignored. |
594 |
+ |
|
595 |
+ |
12. TIBDataSet, TIBQuery, TIBTable: additions: |
596 |
+ |
function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean; |
597 |
+ |
function GetPerfStatistics(var stats: TPerfCounters): boolean; |
598 |
+ |
property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics; |
599 |
+ |
|
600 |
+ |
GetRowsAffected returns the affected row counts from the last insert/update/delete |
601 |
+ |
if EnableStatistics = true then GetPerfStatistics returns the current stats |
602 |
+ |
counters for the select query. Note: stats accumulate after each fetch from |
603 |
+ |
the database. To get total query cost after open, call the "Last" method |
604 |
+ |
and then GetPerfStatistics. |
605 |
+ |
|
606 |
+ |
See ibx/examples/consolemode for an example of the use of GetPerfStatistics |
607 |
+ |
|
608 |
+ |
13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated |
609 |
+ |
in parenthesises. |
610 |
+ |
|
611 |
+ |
14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3 |
612 |
+ |
SQL identifiers are always delimited by double quotes. If false, then they are |
613 |
+ |
only delimited if the identifier is a reserved word, contains lower case or special |
614 |
+ |
characters. Set this property to true to retain previous behaviour. |
615 |
+ |
|
616 |
+ |
15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names |
617 |
+ |
are now inserted in double quotes if not Reserved Words or valid SQL Identifiers. |
618 |
+ |
|
619 |
+ |
16. TIBDataSet, TIBQuery, TIBTable: addition: |
620 |
+ |
property MasterDetailDelay: integer {defaults to zero} |
621 |
+ |
|
622 |
+ |
When non-zero and the dataset is a detail table referencing a master table |
623 |
+ |
through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery) |
624 |
+ |
then a synchronisation delay is added (in milliseconds) between the master |
625 |
+ |
row changing and the detail dataset being re-opened. If the master dataset |
626 |
+ |
is scrolled before the delay expires then the delay is reset. This can be used |
627 |
+ |
to avoid performance overheads when scrolling through a large master dataset. |
628 |
+ |
|
629 |
+ |
Note: uses fptimer and hence requires a thread manager. Under Linux the |
630 |
+ |
chreads unit must be included in your project. TTimer is not used in order |
631 |
+ |
to avoid an LCL dependency. Requires FPC 3.0.2 or later. |
632 |
+ |
|
633 |
+ |
17. TIBExtract: User role grants now excluded when etGrantsToUser not specified |
634 |
+ |
with Extract Option eoDatabase. |
635 |
+ |
|
636 |
+ |
18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428 |
637 |
+ |
When a deLayoutChanged event is reported on the ListSource dataset, the |
638 |
+ |
combobox text is updated. This allows a listsource (detail) to be in a Master/Detail |
639 |
+ |
relationship with the control's datasource (master). |
640 |
+ |
|
641 |
+ |
19. TIBExtract: Full BigInt value range now supported for Generators/Sequences. |
642 |
+ |
|
643 |
+ |
20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their |
644 |
+ |
stubs. Pedantic fix really, as procedures output in dependency order anyway. |
645 |
+ |
|
646 |
+ |
21. TIBExtract: Package Headers and Package Bodies are now included in the extracted |
647 |
+ |
DDL (Firebird 3 and later only). |
648 |
+ |
|
649 |
+ |
22. TIBLookupComboBox Autocomplete Fixes: |
650 |
+ |
i. Only appended text is now selected after autocomplete. |
651 |
+ |
ii. Uppercase keys no longer ignored for autocomplete. |
652 |
+ |
iii. Retain Prefix case is now honoured correctly. |
653 |
+ |
iv. When a DataSource is assigned, typing after autocomplete now extends prefix |
654 |
+ |
before autocomplete performed. i.e. behaviour now the same as when |
655 |
+ |
no DataSource assigned. |
656 |
+ |
|
657 |
+ |
23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring |
658 |
+ |
between SQL statements. |
659 |
+ |
|
660 |
+ |
24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then |
661 |
+ |
ObjectNames are converted to upper case before matching against metadata object |
662 |
+ |
names, unless the objectname is delimited by double quotes, in which case, the |
663 |
+ |
double quotes are removed and the remaining string is used (unmodified) to match |
664 |
+ |
against the metadata object name. |
665 |
+ |
|
666 |
+ |
If true then the ObjectName is used as is without modification and matched |
667 |
+ |
against the metadata object name. No attempt is made to remove double quotes. |
668 |
+ |
|
669 |
+ |
25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used |
670 |
+ |
with eoTrigger, these extract types can be used to select only Database Triggers, |
671 |
+ |
or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types. |
672 |
+ |
|
673 |
+ |
26. TIBXScript: If an exception occurs during the processing of a statement, the |
674 |
+ |
statement separate character is now reset to the default (';'). |
675 |
+ |
|
676 |
+ |
27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect. |
677 |
+ |
|
678 |
+ |
28. TIBXScript: Transaction is no longer automatically reactivated immediately processing |
679 |
+ |
a commit or reconnect statement and instead activated only when next SQL statement |
680 |
+ |
is executed. |
681 |
+ |
|
682 |
+ |
29. TIBSQL.HasField should no longer generate and exception when the field does not exist. |
683 |
+ |
|
684 |
+ |
30. TIBXScript: case insensitive regex now used when matching statements instead of |
685 |
+ |
converting statement to upper case. |
686 |
+ |
|
687 |
+ |
31. TIBExtract: metadata comments now supported. New published property |
688 |
+ |
IncludeMetaDataComments (default true). If true then metadata comments included |
689 |
+ |
in extracted DDL. New Extract Object member eoComments. This may be used with |
690 |
+ |
ExtractObject method to list all metadata comments. |
691 |
+ |
|
692 |
+ |
32. TIBExtract: ListObjectNames method added. |
693 |
+ |
|
694 |
+ |
33. Updated Database component editor to support additional connection string |
695 |
+ |
types. |
696 |

IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000 |
698 |
+ |
|
699 |
+ |
NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO |
700 |
+ |
AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS |
701 |
+ |
RELEASE. |
702 |
+ |
|
703 |
+ |
NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE. |
704 |
+ |
|
705 |
+ |
1. IBExtract: Identity columns - add additional check for null column for generator name. |
706 |
+ |
|
707 |
+ |
2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses. |
708 |
+ |
The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further |
709 |
+ |
information). However, this is also a very useful mechanism for returning updated computed by |
710 |
+ |
column values. Values returned as a result of executing an Insert or Update statement |
711 |
+ |
replace existing values in the current row for each corresponding column. |
712 |
+ |
|
713 |
+ |
Previously, if a dataset's select query included read only (computed by) fields then |
714 |
+ |
an automatic row refresh was performed after an insert or update query had been processed, |
715 |
+ |
irrespective of the setting of the "ForcedUpdates" property. This has changed such |
716 |
+ |
that an automatic refresh is no longer performed if an insert or update query contains |
717 |
+ |
a returning clause that updates one or more fields on the current row. A full row |
718 |
+ |
refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any |
719 |
+ |
field values and the select query contains read only fields. Use of Insert/update |
720 |
+ |
returning should be significantly more efficient than executing a refresh query. |
721 |
+ |
|
722 |
+ |
This behaviour change is intended to be backwards compatible and there should be no need to change |
723 |
+ |
existing programs, other than to improve performance by using the new capability. |
724 |
+ |
|
725 |
+ |
3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as |
726 |
+ |
they are called when the dataset row is being deleted, there is no value in |
727 |
+ |
updating the current record from the query result. Instead, a new event handler |
728 |
+ |
"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and |
729 |
+ |
an OnDeleteReturning event handler is provided then it is called with the IResults returned |
730 |
+ |
by the query. The event handler can then interrogate the query results and |
731 |
+ |
perform whatever action is necessary. For example to confirm, to the user, |
732 |
+ |
the deletion of a row with the returned values. |
733 |
+ |
|
734 |
+ |
4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for |
735 |
+ |
any Computed By or Identity Columns. The IBTables example has been updated to |
736 |
+ |
illustrate the computation of the employee Full Name on update. |
737 |
+ |
|
738 |
+ |
5. TIBTable: The GeneratorField property is now published. |
739 |
+ |
|
740 |
+ |
6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List. |
741 |
+ |
When InsertSQL is generated, the Identity columns are not included in the list of values to |
742 |
+ |
be inserted. A RETURNING clause is added to the insert statement to return the value of |
743 |
+ |
each Identity column after the insert is executed. |
744 |
+ |
|
745 |
+ |
7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |
746 |
+ |
Similarly Insert Property Editor now generates Insert SQL with Computed By fields in |
747 |
+ |
Insert..Returning clause. |
748 |
+ |
|
749 |
+ |
8. TIBGenerator: small performance improvement by not preparing query each time |
750 |
+ |
a new value is generated. |
751 |
+ |
|
752 |
+ |
9. TIBSQL: Free resources when transaction changed - ensures new transaction is used. |
753 |
+ |
|
754 |
+ |
10. Property editors will now sync table name to a System Table when "Include System |
755 |
+ |
Tables" is selected and the query is for a System Table. |
756 |
+ |
|
757 |
+ |
11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field |
758 |
+ |
values are no longer converted to milliseconds from TDateTime and then back again |
759 |
+ |
to TDateTime (the conversion to milliseconds is the default TDataset approach). |
760 |
+ |
|
761 |
+ |
12. Property Editors handling of Stored Procedures. |
762 |
+ |
* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and |
763 |
+ |
which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select |
764 |
+ |
query). |
765 |
+ |
* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2). |
766 |
+ |
|
767 |
+ |
13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName |
768 |
+ |
can be used to select a package. If non-empty, the stored procedure name is |
769 |
+ |
expected to be a stored procedure defined in the specified package and the |
770 |
+ |
generated SQL will be as required for a stored procedure located in a package. |
771 |
+ |
|
772 |
+ |
14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include |
773 |
+ |
a "Package Name" drop down box to allow selection of a Firebird 3 Package from |
774 |
+ |
which a stored procedure can be selected. With no package name selected, non-package |
775 |
+ |
stored procedures are listed. |
776 |
+ |
|
777 |
+ |
15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting |
778 |
+ |
for password on reconnect. |
779 |
+ |
|
780 |
+ |
16. TIBDatabase: use IAttachment for connection default character set id, code page |
781 |
+ |
and character set name. |
782 |
+ |
|
783 |
+ |
17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise |
784 |
+ |
DB info lookups" |
785 |
+ |
|
786 |
+ |
18. IBExtract: now supports DDL Triggers and Grants to DDL objects. |
787 |
+ |
|
788 |
+ |
19. Add a property Editor for TIBUpdate.RefreshSQL. |
789 |
+ |
|
790 |
+ |
20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input |
791 |
+ |
parameters. This stops an exception being raised when the field cannot be |
792 |
+ |
located in the record buffer. |
793 |
+ |
|
794 |
+ |
21. Property Editors now automatically include System Tables when opened and when the query table |
795 |
+ |
is a System Table. |
796 |
+ |
|
797 |
+ |
22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception. |
798 |
+ |
This avoids errors due to a stale SQRB or SRB being used for the next query. |
799 |
+ |
|
800 |
+ |
23. IBServices: Service attach parameters now include "expected_db". This is used to |
801 |
+ |
add the SPB item isc_spb_expected_db. This names a database using |
802 |
+ |
an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a |
803 |
+ |
database. examples/services re-written to illustrate use of "expected_db". |
804 |
+ |
|
805 |
+ |
24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout. |
806 |
+ |
This avoids truncated backups when the server returns a timeout (busy) response. |
807 |
+ |
|
808 |
+ |
25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase. |
809 |
+ |
|
810 |
+ |
26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local |
811 |
+ |
databasenames. These are respectively expanded to the local system's temp directory |
812 |
+ |
(including trailing delimiter) or to a prescribed data directory (including |
813 |
+ |
trailing delimiter). Under Unix systems the data directory is a hidden directory |
814 |
+ |
in the user's home directory. The hidden directory name is either the string returned |
815 |
+ |
from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'. |
816 |
+ |
Under Windows, the directory is the same as the Data Directory as decribed |
817 |
+ |
above but instead prefixed by the User's application data path. These may be |
818 |
+ |
used to improve application portability for Personal Databases. |
819 |
+ |
|
820 |
+ |
27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef |
821 |
+ |
this has not worked for a long time and is not useful either. FieldDefs should be |
822 |
+ |
managed using the Fields Editor as with any other dataset. To access the fields |
823 |
+ |
editor for a TIBTable component, double click on the component. The fields editor |
824 |
+ |
is then displayed. |
825 |
+ |
|
826 |
+ |
28. TIBDatabaseInfo: new properties/function |
827 |
+ |
* DateDBCreated (returns date/time database created) |
828 |
+ |
* TransactionCount (returns no. of active transactions) |
829 |
+ |
* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only). |
830 |
+ |
* PagesFree (Firebird 3 or later) |
831 |
+ |
* PagesUsed (Firebird 3 or later) |
832 |
+ |
* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only) |
833 |
+ |
* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only) |
834 |
+ |
|
835 |
+ |
29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo. |
836 |
+ |
|
837 |
+ |
30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later). |
838 |
+ |
|
839 |
+ |
31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable |
840 |
+ |
the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later). |
841 |
+ |
|
842 |
+ |
32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced |
843 |
+ |
in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from |
844 |
+ |
firing during backup and restore. |
845 |
+ |
|
846 |
+ |
33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options |
847 |
+ |
for verbose output using the new property "StatisticsRequested". |
848 |
+ |
see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats |
849 |
+ |
|
850 |
+ |
34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later). |
851 |
+ |
|
852 |
+ |
35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin" |
853 |
+ |
palette. This uses the online validation feature added in Firebird 2.5. The |
854 |
+ |
services's properties enable inclusion/exclusion of tables and indexes using |
855 |
+ |
regular expressions. See. |
856 |
+ |
https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation |
857 |
+ |
|
858 |
+ |
36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger |
859 |
+ |
option on a database. |
860 |
+ |
|
861 |
+ |
37. TIBCustomService: Assign method implemented to allow copying of service login |
862 |
+ |
context between service API components. "Detach" method now only detaches |
863 |
+ |
service when last reference to the service interface detaches. Tidy up of |
864 |
+ |
code for SetActive and Attach methods including password hiding. |
865 |
+ |
|
866 |
+ |
38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only |
867 |
+ |
and used to determine the auth method and protocol used for the connection. |
868 |
+ |
|
869 |
+ |
39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using |
870 |
+ |
a Create Database Statement generated by IBX. |
871 |
+ |
|
872 |
+ |
40. All IBServices now have an additional published property "PortNo". This may |
873 |
+ |
be set to a non-standard port number when necessary. If zero then the default |
874 |
+ |
port number is used. |
875 |
+ |
|
876 |
+ |
41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard |
877 |
+ |
and not just the mouse. |
878 |
+ |
|
879 |
+ |
42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added. |
880 |
+ |
|
881 |
+ |
43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the |
882 |
+ |
image index and selected image index for each node to be set from a database field. |
883 |
+ |
|
884 |
+ |
44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included |
885 |
+ |
then database schema includes grants to all users. If not present then the |
886 |
+ |
only user grants included are those to User PUBLIC. |
887 |
+ |
|
888 |
+ |
45. TIBTreeView: performance improvement. When expanding include both expanded node |
889 |
+ |
and child nodes in dataset. |
890 |
+ |

IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000 |
893 |
+ |
|
894 |
+ |
1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf |
895 |
+ |
changes. |
896 |
+ |
|
897 |
+ |
2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString. |
898 |
+ |
Bug could result in truncated multi-byte character set values. |
899 |
+ |
|
900 |
+ |
3. Changes consequential on moving fbintf character set utility functions from |
901 |
+ |
IFirebirdAPI to IAttachment. |
902 |
+ |
|
903 |
+ |
4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true |
904 |
+ |
|
905 |
+ |
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally |
906 |
+ |
results in autocomplete ignoring prefix text. |
907 |
+ |
|
908 |
+ |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when |
909 |
+ |
entering a new name into the text box. |
910 |
+ |
|
911 |
+ |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by |
912 |
+ |
Firebird rather than recomputing it. |
913 |
+ |
|
914 |
+ |
8. Property Editor positioning tidy up: All IBX Property editors should now be |
915 |
+ |
screen centre. Previously some were "poDesigned" which may be inappropriate |
916 |
+ |
for multi monitor desktops. |
917 |
+ |
|
918 |
+ |
10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. |
919 |
+ |
|
920 |
+ |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending |
921 |
+ |
a transaction and always reset the object. |
922 |
+ |
|
923 |
+ |
12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows. |
924 |
+ |
|
925 |
+ |
13. TIBXScript: Allow for override of database filename in Create Database statements. |
926 |
+ |
|
927 |
+ |
14. IBLocaldb: Support initialisation of the database from an SQL script in addition |
928 |
+ |
to a gbak format archive. |
929 |
+ |
|
930 |
+ |
15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised. |
931 |
+ |
|
932 |
+ |
16. IBLocaldb: Drop database if error creating an empty database. |
933 |
+ |
|
934 |
+ |
17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset |
935 |
+ |
unless selected node not in current dataset. |
936 |
+ |
|
937 |
+ |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) |
938 |
+ |
to TIBCustomService, and IBlocalDB code tidy up. |
939 |
+ |
|
940 |
+ |
19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable |
941 |
+ |
behaviour due to uninitialised variable. |
942 |
+ |
|
943 |
+ |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from |
944 |
+ |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. |
945 |
+ |
|
946 |
+ |
21. IBSQL: When Database changed ensure that all resources are freed. |
947 |
+ |
|
948 |
+ |
22. IBCustomDataset: When database changed ensure that queries an unprepared. |
949 |
+ |
|
950 |
+ |
23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include: |
951 |
+ |
* Line Wrap on SQL Token boundaries (on user command) |
952 |
+ |
* auto-complete table names in drop down list of table names |
953 |
+ |
* Double click on tablename or field name adds to SQL text |
954 |
+ |
|
955 |
+ |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). |
956 |
+ |
|
957 |
+ |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to |
958 |
+ |
TVariantArray. Seems to avoid memory corruption in Windows (probably a |
959 |
+ |
workaround for a problem in fpc 3.0.4 win64). |
960 |
+ |
|
961 |
+ |
26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open. |
962 |
+ |
|
963 |
+ |
27. IBDatabaseInfo: Remove memory leak when accessing database operation counts. |
964 |
+ |
|
965 |
+ |
IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000 |
966 |
+ |
|
967 |
+ |
1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to |
968 |
+ |
include remote system name. |
969 |
+ |
|
970 |
+ |
2. TIBExtract: No longer include comment header and COMMIT statement for empty |
971 |
+ |
tables when data included in output. |
972 |
+ |
|
973 |
+ |
3. Profiling: IBSQL now has conditional compilation flags to enable query performance |
974 |
+ |
and timing information to be written to stdout. This may be used to locate |
975 |
+ |
performance bottlenecks. |
976 |
+ |
|
977 |
+ |
4. SQLParser: only call "OnChanging" event handler when value is different. |
978 |
+ |
|
979 |
+ |
5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit |
980 |
+ |
|
981 |
+ |
6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures |
982 |
+ |
that BindFields is called when the query is next activated. Avoids FieldName |
983 |
+ |
not found error. |
984 |
+ |
|
985 |
+ |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general |
986 |
+ |
purpose and allows the programmer to define any action they want for Update, Insert |
987 |
+ |
or Delete. This may be complex SQL (similar to a Trigger), application specific |
988 |
+ |
filtering of updates, or use of statements such as Grant or Revoke instead of |
989 |
+ |
normal DML. See User Manual for more information. |
990 |
+ |
|
991 |
+ |
IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000 |
992 |
+ |
|
993 |
+ |
1. TIBEvents: Fix uninitialised variable that could result in lost events. |
994 |
+ |
|
995 |
+ |
2. TIBExtract: Added support for FB3 "USAGE" privilege. |
996 |
+ |
|
997 |
+ |
3. TIBExtract: data formatted as Charset set "octets" is now output using |
998 |
+ |
hexadecimal notation. |
999 |
+ |
|
1000 |
+ |
4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements |
1001 |
+ |
using a simple XML format. |
1002 |
+ |
|
1003 |
+ |
5. TIBExtract: extract of individual Triggers and Stored Procedures can now include |
1004 |
+ |
grants to these objects. |
1005 |
+ |
|
1006 |
+ |
6. TIBExtract: Stored Procedures and Views output in dependency order to avoid |
1007 |
+ |
dependency problems restoring complex databases. |
1008 |
+ |
|
1009 |
+ |
7. TIBXScript: This component has been restructured to allow for the processing of |
1010 |
+ |
embedded XML in INSERT statements and to support interactive sources in addition |
1011 |
+ |
to non-interactive data sources such as files. |
1012 |
+ |
|
1013 |
+ |
8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported. |
1014 |
+ |
|
1015 |
+ |
9. TIBXScript: ISQL compatiable Set statements are now supported: |
1016 |
+ |
SET SQL DIALECT |
1017 |
+ |
SET TERM |
1018 |
+ |
SET AUTODDL |
1019 |
+ |
SET BAIL |
1020 |
+ |
SET ECHO |
1021 |
+ |
SET COUNT |
1022 |
+ |
SET STATS |
1023 |
+ |
SET NAMES <character set> |
1024 |
+ |
|
1025 |
+ |
10. IBVersion unit added to hold current IBX Version Number information. |
1026 |
+ |
|
1027 |
+ |
11. TIBExtract: Use character rather than byte length for VarChar procedure arguments., |
1028 |
+ |
and domain definitions. |
1029 |
+ |
|
1030 |
+ |
12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers |
1031 |
+ |
fully supported. |
1032 |
+ |
|
1033 |
+ |
13. TIBExtract: when a database dump includes data, the generator values are now also set. |
1034 |
+ |
|
1035 |
+ |
14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later. |
1036 |
+ |
|
1037 |
+ |
IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000 |
1038 |
+ |
|
1039 |
+ |
See also doc/IBX4LazarusGuide.pdf for important information on |
1040 |
+ |
upgrading to IBX2. |
1041 |
+ |
|
1042 |
+ |
1. Size property of TIBStringField is now the width in characters of the field |
1043 |
+ |
and not the byte length. This applies only to multi-byte character sets such |
1044 |
+ |
as UTF8. The original approach aligned with TStringField. However, the TStringField |
1045 |
+ |
code is not recognised as a bug and hence this change to align the behaviour. |
1046 |
+ |
The TStringField change is expected in fpc 3.2.0. |
1047 |
+ |
|
1048 |
+ |
2. A new property AutoFieldSize: boolean has been added to TIBStringField. When |
1049 |
+ |
true (default) then Size property value saved in the lfm is ignored. Size is |
1050 |
+ |
always set from the dynamic information read from the database. It is unclear |
1051 |
+ |
why anyone would want to override this and set Size to false. |
1052 |
+ |
|
1053 |
+ |
3. ibxscript: should now handle correctly a Case..End statement within a procedure |
1054 |
+ |
block. |
1055 |
+ |
|
1056 |
+ |
4. IBDatabase: new property - CreateIfNotExists. If true and database does not |
1057 |
+ |
exist when an attempt is made to connect to it (run time only) then an attempt |
1058 |
+ |
is made to create the database. |
1059 |
+ |
|
1060 |
+ |
5. IBDatabase: new event - OnCreateDatabase. This event is called after a database |
1061 |
+ |
has been successfully created as a result of a call to CreateDatabase or when |
1062 |
+ |
creating a database after it was found not to exist. |
1063 |
+ |
|
1064 |
+ |
6. DBControlGrid: a race condition could result in the wrong row image being |
1065 |
+ |
written to the cache. This has been avoided by a trip round the message |
1066 |
+ |
loop before rendering the row image. |
1067 |
+ |
|
1068 |
+ |
7. DBControlGrid: It is strongly recommended not to open the source DataSet for |
1069 |
+ |
a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is |
1070 |
+ |
known to risk corrupt rendering of row images when the control is first |
1071 |
+ |
displayed. If necessary use "Application.QueueAsyncCall" to delay opening |
1072 |
+ |
of the dataset (see DBControlGrid examples) until the Form's Window has been created. |
1073 |
+ |
|
1074 |
+ |
8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with |
1075 |
+ |
a TDateEdit control located on an editor panel. |
1076 |
+ |
|
1077 |
+ |
9. TIBExtract: brought up-to-date plus many bug fixes. |
1078 |
+ |
|
1079 |
+ |
10. DBControlGrid: Removed memory leak when updating rows. |
1080 |
+ |
|
1081 |
+ |
11. TIBCMLocalDBSupport: fixed invalid free on upgrade. |
1082 |

IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100 |
1084 |
+ |
|
1085 |
+ |
1. IBCustomDataset: When calling SetCodePage, no longer request transliteration |
1086 |
+ |
when target codepage is CP_NONE. This is a workaround for |
1087 |
+ |
http://bugs.freepascal.org/view.php?id=30622. |
1088 |
+ |
|
1089 |
+ |
2. DBLog option removed from TIBStatisticalService - not supported by server |
1090 |
+ |
since Firebird 1.5. |
1091 |
+ |
|
1092 |
+ |
3. ibxscript: An error is no longer generated for "on commit preserve rows" or |
1093 |
+ |
similar. |
1094 |
+ |
|
1095 |
+ |
4. IBCodePage: updated mapping between codepages and character id. |
1096 |
+ |
|
1097 |
+ |
5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in |
1098 |
+ |
Firebird. Character sets with a char width of two are not UTF16. |
1099 |
+ |
|
1100 |
+ |
6. Strings received from the database are now always transliterated into UTF8 |
1101 |
+ |
regardless of the database character set or connection character set. This |
1102 |
+ |
is for compatibility with the LCL. |
1103 |
+ |
|
1104 |
+ |
IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100 |
1105 |
+ |
|
1106 |
+ |
1. IBBlob: Defer reading of blob until read method called. This avoids having to |
1107 |
+ |
read in an entire blob just to get the size of the blob. General performance |
1108 |
+ |
improvement when opening datasets containing blobs. |
1109 |
+ |
|
1110 |
+ |
2. Clearing a Blob now sets the corresponding field's modified flag. |
1111 |
+ |
|
1112 |
+ |
3. IBLookupCombo: When not performing auto-complete, original query sort order |
1113 |
+ |
is now used. |
1114 |
+ |
|
1115 |
+ |
4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically |
1116 |
+ |
determined. |
1117 |
+ |
|
1118 |
+ |
5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened. |
1119 |
+ |
|
1120 |
+ |
6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post |
1121 |
+ |
lazarus 1.6.0 |
1122 |
+ |
|
1123 |
+ |
7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages" |
1124 |
+ |
compilation error. |
1125 |
+ |
|
1126 |
+ |
IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100 |
1127 |
+ |
|
1128 |
+ |
1. No character set specified for connection: when a text blob is retrieved, the |
1129 |
+ |
character set is determined by looking up the native character set using then |
1130 |
+ |
Firebird API. Otherwise a text mode blob is assumed to have the same character |
1131 |
+ |
set as the connection. |
1132 |
+ |
|
1133 |
+ |
2. TIBGUIInterface: this is an internal interface. Minor type changes to allow |
1134 |
+ |
for Login Dialog returing a change to the database path. |
1135 |
+ |
|
1136 |
+ |
3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name |
1137 |
+ |
to be changed from that given in the TIBDatabase/TIBServer component and for the |
1138 |
+ |
entered value to be saved on a project specific basis (design time only). |
1139 |
+ |
|
1140 |
+ |
4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the |
1141 |
+ |
column fieldname. If they are the same then it is acts as a look up for the KeyValue |
1142 |
+ |
Otherwise, it sets the column text to the selected ListField Value. |
1143 |
+ |
|
1144 |
+ |
5. IBDynamicGrid: Only visible columns are now taken into account When recalculating |
1145 |
+ |
column width. |
1146 |
+ |
|
1147 |
+ |
6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given |
1148 |
+ |
and a case insensitive search is requested. |
1149 |
+ |
|
1150 |
+ |
7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls |
1151 |
+ |
or column ListSource. |
1152 |
+ |
|
1153 |
+ |
8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an |
1154 |
+ |
unprepare) when closing and the text has not changed. |
1155 |
+ |
|
1156 |
+ |
9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer. |
1157 |
+ |
Less likely to cause a cursor re-use error on Windows. |
1158 |
+ |
|
1159 |
+ |
10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin. |
1160 |
+ |
Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0. |
1161 |
+ |
|
1162 |
+ |
11. TIBTreeView: Guard against nil destination on record changed |
1163 |
+ |
|
1164 |
+ |
12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a |
1165 |
+ |
string type with the code page set to reflect the returned field encoding after |
1166 |
+ |
Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for |
1167 |
+ |
earlier versions. |
1168 |
+ |
|
1169 |
+ |
13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString |
1170 |
+ |
will now result in transliteration to the code page specified for the Firebird driver |
1171 |
+ |
if the assigned string has a different code page. FPC 3.0.0 onwards only. |
1172 |
+ |
|
1173 |
+ |
14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter |
1174 |
+ |
is ignored and the lc_ctype value, when the database is opened, is set to align with |
1175 |
+ |
the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure |
1176 |
+ |
platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC |
1177 |
+ |
3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when |
1178 |
+ |
the GETACP is used to determine the Windows code page. |
1179 |
+ |
|
1180 |
+ |
15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set |
1181 |
+ |
name used as the lc_ctype when the database was opened. Only valid while the |
1182 |
+ |
Database is connected. |
1183 |
+ |
|
1184 |
+ |
16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage |
1185 |
+ |
id that corresponds to the DefaultCharSetName. |
1186 |
+ |
|
1187 |
+ |
IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000 |
1188 |
+ |
|
1189 |
+ |
1. Unix: If Firebird Embedded Server shared object is loaded and a local database |
1190 |
+ |
path is given and database attach fails due to access permission issues on the |
1191 |
+ |
temp directory or security database, then the attach is retried with "localhost:" |
1192 |
+ |
prefixing the databasename. This should avoid problems when the database has to |
1193 |
+ |
be accessed by a local (e.g. classic) server and libfbembed is used. |
1194 |
+ |
|
1195 |
+ |
2. Windows: revised search order for Firebird DLL: |
1196 |
+ |
i. The Firebird Embedded Server in the application Directory. |
1197 |
+ |
ii. If the FIREBIRD environment variable is set then the directory this |
1198 |
+ |
points to is searched for the FB Client DLL and then then underlying |
1199 |
+ |
"bin" directory. |
1200 |
+ |
iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances |
1201 |
+ |
is used to locate the Firebird installation directory and the underlying |
1202 |
+ |
"bin" directory is searched for the FB Client DLL. |
1203 |
+ |
iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x |
1204 |
+ |
are searched for the FB Client DLL. |
1205 |
+ |
v. The PATH Environment variable is used to search for the FB Client DLL. |
1206 |
+ |
vi. Finally the PATH Environment variable is used to search for IBASE.DLL. |
1207 |
+ |
|
1208 |
+ |
3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine. |
1209 |
+ |
See doc/readme.scriptengine and example applications. |
1210 |
+ |
|
1211 |
+ |
4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to |
1212 |
+ |
simplify the use of the embedded firebird server on both Linux and Windows platforms. |
1213 |
+ |
See dpc/readme.localdatabase and example applications. |
1214 |
+ |
|
1215 |
+ |
5. IBDynamicGrid: Reordering on column header click should now also work for |
1216 |
+ |
dynamic columns. |
1217 |
+ |
|
1218 |
+ |
6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition |
1219 |
+ |
between incrementing/decrementing the lock count and signalling the event. |
1220 |
+ |
|
1221 |
+ |
IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000 |
1222 |
+ |
|
1223 |
+ |
1.3.2 was never formally released and only made available as beta copies. |
1224 |
+ |
|
1225 |
+ |
1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo |
1226 |
+ |
|
1227 |
+ |
2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column |
1228 |
+ |
|
1229 |
+ |
3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early |
1230 |
+ |
|
1231 |
+ |
4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset |
1232 |
+ |
i.e. when it is a calculated field |
1233 |
+ |
|
1234 |
+ |
5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid. |
1235 |
+ |
This problem was due to a race condition between recalculating row heights and |
1236 |
+ |
determining which row was selected by the mouse click. The row height calculation |
1237 |
+ |
is now deferred by an extra trip round the message loop allowing the row to |
1238 |
+ |
be always calculated on the current grid layout rather than risking it being |
1239 |
+ |
calculated on the grid layout after the expanded row has been shrunk. |
1240 |
+ |
|
1241 |
+ |
6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on |
1242 |
+ |
Windows. |
1243 |
+ |
|
1244 |
+ |
7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer; |
1245 |
+ |
These properties allow the (Firebird) character set name for the field and the max number of bytes per character |
1246 |
+ |
to be determined at runtime. See doc/readme.charactersets.html. |
1247 |
+ |
|
1248 |
+ |
8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from |
1249 |
+ |
TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html. |
1250 |
+ |
|
1251 |
+ |
9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from |
1252 |
+ |
TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of |
1253 |
+ |
1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html. |
1254 |
+ |
|
1255 |
+ |
Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated |
1256 |
+ |
from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero |
1257 |
+ |
implies no truncation. |
1258 |
+ |
|
1259 |
+ |
10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active. |
1260 |
+ |
|
1261 |
+ |
11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state |
1262 |
+ |
(avoids "Not in Edit Mode" error). |
1263 |
+ |
|
1264 |
+ |
12. IBDynamicGrid: Correctly resize grid when one column width plus indicator. |
1265 |
+ |
|
1266 |
+ |
13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling |
1267 |
+ |
DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control. |
1268 |
+ |
|
1269 |
+ |
14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent. |
1270 |
+ |
|
1271 |
+ |
15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls |
1272 |
+ |
|
1273 |
+ |
16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked. |
1274 |
+ |
|
1275 |
+ |
17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened. |
1276 |
+ |
|
1277 |
+ |
IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100 |
1278 |
+ |
|
1279 |
+ |
1. OnCloseUp Event Handler added to TDBLookupProperties |
1280 |
+ |
|
1281 |
+ |
2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids |
1282 |
+ |
problem with row size when exception is called. |
1283 |
+ |
|
1284 |
+ |
3. IBLookupComboEditBox: Force pending autocomplete on combobox exit. |
1285 |
+ |
|
1286 |
+ |
4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if |
1287 |
+ |
in a TCustomComboBox and ignores return key if in a TCustomMemo |
1288 |
+ |
|
1289 |
+ |
5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text |
1290 |
+ |
keyed in i.e. when autocomplete not performed |
1291 |
+ |
|
1292 |
+ |
6. Cleanup of "Uses" clauses and add console mode support. IBX should now support |
1293 |
+ |
console mode applications with all LCL required functions (builtin dialogs and |
1294 |
+ |
cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is |
1295 |
+ |
not included in your project, IBX should compile and link with a console mode program. |
1296 |
+ |
See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a |
1297 |
+ |
console mode application or the IDE will automatically assume that your |
1298 |
+ |
application is GUI based. Instead, you should include the ibexpressconsolemode package. |
1299 |
+ |
|
1300 |
+ |
IMPORTANT NOTE: IBDialogs must be included in GUI applications in order |
1301 |
+ |
to use the built in dialogs and cursor management. IBDialogs is |
1302 |
+ |
included by default if "ibexpress" is in your project source's "uses" clause. |
1303 |
+ |
This should be the case for all projects created through the IDE. This is why |
1304 |
+ |
you do not want to add the ibexpress package to console mode applications. The |
1305 |
+ |
ibexpressconsolemode package has been created to allow console mode programs |
1306 |
+ |
to avoid adding LCL dependencies when using IBX, while still having the |
1307 |
+ |
unit search paths set up correctly. |
1308 |
+ |
|
1309 |
+ |
Existing users should check to ensure that the "ibexpress" unit is included in |
1310 |
+ |
each project's source file (*.lpr). |
1311 |
+ |
|
1312 |
+ |
You may find that in order for the IDE to recognise that ibexpressconsolemode |
1313 |
+ |
exists, you have to first open the package in the IDE and then close it. This |
1314 |
+ |
adds it to the most recently accessed packages list. To make it permanently |
1315 |
+ |
available, add the package name to lazarus' staticpackages.inc file. |
1316 |
+ |
|
1317 |
+ |
Thanks to Julio Jiménez for suggesting support of console mode. |
1318 |
+ |
|
1319 |
+ |
7. SQL Parser can now accept quoted strings that include new lines |
1320 |
+ |
|
1321 |
+ |
8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end |
1322 |
+ |
of text on start of edit. This is particularly useful when tabbing to a |
1323 |
+ |
column and then inserting text. |
1324 |
+ |
|
1325 |
+ |
9. New Examples provided for IB Services and ISQLMonitor. |
1326 |
+ |
|
1327 |
+ |
10. Fix error when writing to blob streams that recorded only the last buffer |
1328 |
+ |
write in the blob stream. In most cases, this did not cause a problem as the |
1329 |
+ |
IB Blob Stream is written in a single write. However, with the TDBImage, write |
1330 |
+ |
of a graphic type prefix was lost which caused a problem when the image could |
1331 |
+ |
not be automatically recognised. |
1332 |
+ |
|
1333 |
+ |
11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor |
1334 |
+ |
already open" errors due to random numbers used for the cursor name being identical. |
1335 |
+ |
|
1336 |
+ |
12. IBTable: corrected error that could result in an "Index out of bounds" error |
1337 |
+ |
when opening the table and the Primary Key is the last or only column in the |
1338 |
+ |
table. Thanks to Rick Hoover for the fix. |
1339 |
+ |
|
1340 |
+ |
13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead |
1341 |
+ |
of "UTF-8", and update list of available database character sets. Existing |
1342 |
+ |
users should check the current lc_ctype setting in their applications. |
1343 |
+ |
|
1344 |
+ |
IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100 |
1345 |
+ |
|
1346 |
+ |
1. Firebird Services: avoid List Index error when opening a service with an |
1347 |
+ |
empty Params property. |
1348 |
+ |
|
1349 |
+ |
2. IBControls: Fix problem with new link mechanism introduced in 1.2.3. |
1350 |
+ |
Link now set up in Loaded method - avoids occasional failure to apply |
1351 |
+ |
SQL markup on initial open. |
1352 |
+ |
|
1353 |
+ |
3. "Employees" example performance improvements when scrolling. |
1354 |
+ |
|
1355 |
+ |
4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a |
1356 |
+ |
TFrame. Force recaching of selected frame to avoid GTK race (results in a |
1357 |
+ |
random image cached). |
1358 |
+ |
|
1359 |
+ |
5. DBControlGrid: Should now react to changes in panel height at run time. |
1360 |
+ |
|
1361 |
+ |
6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid |
1362 |
+ |
even when further rows exist. |
1363 |
+ |
|
1364 |
+ |
7. DBControlGrid: DefaultRowHeight is no longer a published property as it should |
1365 |
+ |
always be derived from panel height and setting this property can cause confusion. |
1366 |
+ |
Note for existing projects: to avoid a missing property error at run time, |
1367 |
+ |
each form using the DBControlGrid must be opened, updated and saved in the IDE |
1368 |
+ |
in order to remove the property value from the lfm. |
1369 |
+ |
|
1370 |

1372 |
+ |
|
1373 |
+ |
1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always |
1374 |
+ |
call Prepare before setting parameter values. |
1375 |
+ |
|
1376 |
+ |
2. Error message on ParamByName (all cases) not found now includes name of missing parameter. |
1377 |
+ |
|
1378 |
+ |
3. Code tidyup and more robust handling of dsql information result vector. |
1379 |
+ |
|
1380 |
+ |
4. Support for centralised handling of transaction status changes. TIBTransaction |
1381 |
+ |
has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost" |
1382 |
+ |
and "AfterExecQuery". The first three are called after the same event is called |
1383 |
+ |
for an IBCustomDataSet descendent using the Transaction. The fourth is called |
1384 |
+ |
after a call to TIBSQL.ExecQuery, again using this transaction. These new events |
1385 |
+ |
enable monitoring of transaction status changes for a given transaction to be |
1386 |
+ |
handled in a single place. For example, when a change to the dataset occurs |
1387 |
+ |
an indicator can be set that shows the user that in order to save changes, |
1388 |
+ |
the transaction should be committed. Rather than doing this per dataset, this |
1389 |
+ |
can now be done per transaction. |
1390 |
+ |
|
1391 |
+ |
5. TDataSet.CheckBrowseMode automatically posts changes to the current row when |
1392 |
+ |
the dataset is scrolled. However, any changes to the current row are, by default, |
1393 |
+ |
discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now |
1394 |
+ |
have a new property "DataSetCloseAction" that adds automatic posting of changes |
1395 |
+ |
on dataset close. If this property is set to dcDiscardChanges (default) then the |
1396 |
+ |
behaviour is unchanged from previous versions. if the value is set to dcSaveChanges |
1397 |
+ |
then IBX will attempt to post any unsaved changes before the dataset is closed |
1398 |
+ |
(and after the BeforeClose event handler is called). The exception is when the |
1399 |
+ |
dataset is being closed as a result of a transaction rollback. In this case, |
1400 |
+ |
no action is taken and any unsaved changes are discarded. This avoids both |
1401 |
+ |
unnecessary overhead and the risk that a validation error may occur in the Post |
1402 |
+ |
raising an exception and thereby preventing a rollback. |
1403 |
+ |
|
1404 |
+ |
6. String Field sizes and Display Widths should now be correct for multi-byte character sets. |
1405 |
+ |
In earlier versions, the Display Width was set to the maximum byte width rather than the character |
1406 |
+ |
width. Display Widths are now corrected by dividing by the max byte width per character. |
1407 |
+ |
For UTF8 character sets, the byte width is four and hence the Display Width will be |
1408 |
+ |
the byte width divided by 4. The byte width of each character set is determined |
1409 |
+ |
dynamically when the database connection is estabished from the RDB$CHARACTER_SETS |
1410 |
+ |
system table. (see also http://bugs.freepascal.org/view.php?id=27766). |
1411 |
+ |
|
1412 |
+ |
7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string. |
1413 |
+ |
|
1414 |
+ |
8. IBLookupComboEditBox: List should now always be restored to full list when the |
1415 |
+ |
control loses focus. Default Key press default interval reduced to 200ms. |
1416 |
+ |
|
1417 |
+ |
9. DBControlGrid: Ensure that selection is changed to newly appended row, even |
1418 |
+ |
when dataset rows are less than visible rows. |
1419 |
+ |
|
1420 |
+ |
10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource |
1421 |
+ |
does not exist or DataSet is empty. More responsive on dataset open. New event |
1422 |
+ |
OnRestorePosition. Column sort disabled if no header row. |
1423 |
+ |
|
1424 |
+ |
11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset |
1425 |
+ |
while dataset state is dsInsert. Avoids posting errors. |
1426 |
+ |
|
1427 |
+ |
12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to |
1428 |
+ |
avoid conflict with DisableControls/EnableControls with Master/Detail linked tables. |
1429 |
+ |
|
1430 |
+ |
13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes. |
1431 |
+ |
|
1432 |
+ |
14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced |
1433 |
+ |
to solve a specific problem. That is when the dataset cursor is moved (e.g. by |
1434 |
+ |
a grid mouse click and the current row is being edited or inserted. In this case, TDataset |
1435 |
+ |
always "posts" the current record regardless or whether or not it may be more appropriate |
1436 |
+ |
to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the |
1437 |
+ |
"MoveBy" function is implemented by TDataSet. The OnValidatePost event is called |
1438 |
+ |
as the first action of the "Post" method and allows the handler to convert the Post |
1439 |
+ |
into a Cancel if that is the appropriate action on moving to a different row. This is |
1440 |
+ |
achieved by returning with "CancelPost" argument set to true. Note that an exception could be |
1441 |
+ |
raised here, but it may still be more appropriate to validate a post and signal |
1442 |
+ |
a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml) |
1443 |
+ |
|
1444 |
+ |
15. On Unix derived systems, the Firebird library name can now be given as a colon |
1445 |
+ |
separated list. Each library name on the list is tried in turn, in left to right |
1446 |
+ |
order with the first found being used as the firebird library. By default, on Linux, |
1447 |
+ |
the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be |
1448 |
+ |
overidden by the FBLIB environment variable or the OnGetLibraryName function. |
1449 |
+ |
|
1450 |
+ |
Note: when using the libfbembed.so, if you prefix the database name with "localhost:" |
1451 |
+ |
then it will still attempt to access the database via the Firebird Server and will |
1452 |
+ |
require a username and password. If only the pathname is given, then the username |
1453 |
+ |
and password should be omitted and the unix file permissions are used to grant |
1454 |
+ |
access. |
1455 |
+ |
|
1456 |
+ |
IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000 |
1457 |
+ |
|
1458 |
+ |
1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike |
1459 |
+ |
rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid |
1460 |
+ |
that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row |
1461 |
+ |
corresponds to a row of the linked DataSource. Any data aware control on the |
1462 |
+ |
replicated (e.g.) TPanel will then appear to have the appropriate value for the row. |
1463 |
+ |
|
1464 |
+ |
2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase. |
1465 |
+ |
When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change |
1466 |
+ |
takes place during database access. This may be useful when there are performance issues with |
1467 |
+ |
the change of cursor. Setting the property to false suppresses the change of cursor. |
1468 |
+ |
|
1469 |
+ |
3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery |
1470 |
+ |
and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to |
1471 |
+ |
Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of |
1472 |
+ |
making all changes permanent immediately rather than when the transaction is explicitly |
1473 |
+ |
committed. |
1474 |
+ |
|
1475 |
+ |
4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still |
1476 |
+ |
using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature. |
1477 |
+ |
|

1480 |
+ |
Development version only. |

IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000 |
1483 |
+ |
|
1484 |
+ |
1. An internal select SQL Parser is now available for TIBCustomDataset descendents. |
1485 |
+ |
This is typically used during an "OnBeforeOpen" event handler to manipulate the |
1486 |
+ |
"Where" and "Having" clauses to implement user specified filters of arbitrary |
1487 |
+ |
complexity. |
1488 |
+ |
|
1489 |
+ |
2. A new Component Palette entry "Firebird Data Controls" is now available. This has |
1490 |
+ |
three new data aware controls dependent on IBX and which make use of the SQL Parser. |
1491 |
+ |
These are: |
1492 |
+ |
|
1493 |
+ |
- TIBLookupComboEditBox |
1494 |
+ |
- TIBDynamicGrid |
1495 |
+ |
- TIBTreeview |
1496 |
+ |
|
1497 |
+ |
TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete" |
1498 |
+ |
of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation |
1499 |
+ |
to revise the available list and restrict it to items that are prefixed by the |
1500 |
+ |
typed text (either case sensitive or case insensitive). Autoinsert allows a |
1501 |
+ |
newly typed entry to be added to the list dataset and included in the available |
1502 |
+ |
list items. |
1503 |
+ |
|
1504 |
+ |
TIBDynamicGrid is a TDBGrid descendent that provides for: |
1505 |
+ |
- automatic resizing of selected columns to fill the available row length |
1506 |
+ |
- automatic positioning and sizing of a "totals" control, typically at the |
1507 |
+ |
column footer, on a per column basis. |
1508 |
+ |
- DataSet resorting on header row click, sorting the dataset by the selected column. |
1509 |
+ |
A second click on the same header cell reversed the sort order. |
1510 |
+ |
- Support for a "Panel Editor". That is on clicking the indicator column, the row |
1511 |
+ |
is automatically expanded and a panel superimposed on it. The panel can have any |
1512 |
+ |
number of child controls, typically data aware controls with the same datasource |
1513 |
+ |
as the grid allowing for editing of additional fields and more complex editors. |
1514 |
+ |
- Reselection of the same row following resorting. |
1515 |
+ |
- A new cell editor that provides the same functionality as TIBLookupComboEditBox. |
1516 |
+ |
Its properties are specified on a per column basis and allows for one or more |
1517 |
+ |
columns to have their values selected from a list provided by a dataset. |
1518 |
+ |
Autocomplete and autoinsert are also available. The existing picklist editor |
1519 |
+ |
is unaffected by the extension. |
1520 |
+ |
|
1521 |
+ |
TIBTreeView is a data aware TCustomTreeView. |
1522 |
+ |
|
1523 |
+ |
3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a |
1524 |
+ |
zero scale will no longer return an error. An Int64 will be returned instead. |
1525 |
+ |
|
1526 |
+ |
4. TIBTransaction now has events for Before and After Transaction End and a new function |
1527 |
+ |
"GetEndAction" allowing the EndAction to be accessed by these event handlers. |
1528 |
+ |
|
1529 |
+ |
5. TIBQuery can now handle correctly queries which contain the same keyword parameter |
1530 |
+ |
repeated multiple times. |
1531 |
+ |
|
1532 |
+ |
6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error |
1533 |
+ |
check used to get in the way of using Stored Procedures, and "Update or Insert" |
1534 |
+ |
statements. |
1535 |
+ |
|
1536 |
+ |
7. Insert, Modify and Delete property Editors now support Query Generation from |
1537 |
+ |
Stored Procedures. |
1538 |
+ |
|
1539 |
+ |
8. Three new examples illustrate the use of the new IB Controls |
1540 |
+ |
|
1541 |
+ |
|
1542 |
+ |
IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100 |
1543 |
+ |
|
1544 |
+ |
1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter |
1545 |
+ |
setting performance. See "readme.field+param.names in the doc folder.(Thanks to |
1546 |
+ |
Gabor Boros for reporting this problem and for testing the improvements). |
1547 |
+ |
|
1548 |
+ |
2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case. |
1549 |
+ |
See readme.field+param.names in the doc folder. |
1550 |
+ |
|
1551 |
+ |
3. IBX SQL Editors will now automatically add double quotes around column names when the database |
1552 |
+ |
dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word. |
1553 |
+ |
|
1554 |
+ |
4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc |
1555 |
+ |
|
1556 |
+ |
5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once" |
1557 |
+ |
actions. |
1558 |
+ |
|
1559 |
+ |
6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with |
1560 |
+ |
thanks to Yuriy Kopnin for pointing this out). |
1561 |
+ |
|
1562 |
+ |
7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet. |
1563 |
+ |
|
1564 |
+ |
8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types |
1565 |
+ |
for both fields and parameter setting. |
1566 |
+ |
|
1567 |
+ |
9. Changes to the Select SQL in an IBCustomDataset descendent should now be |
1568 |
+ |
visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property. |
1569 |
+ |
|
1570 |
+ |
10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test, |
1571 |
+ |
when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true. |
1572 |
+ |
|
1573 |
+ |
11. TIBTable now has a property editor for "MasterFields" |
1574 |
+ |
|
1575 |
+ |
12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the |
1576 |
+ |
GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters. |
1577 |
+ |
|
1578 |
+ |
13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination |
1579 |
+ |
of settings is unrecognised. Selecting this radio button has no effect on the settings. |
1580 |
+ |

1587 |
+ |
|
1588 |
+ |
1. In a TIBCustomDataset descendent, a generator now only sets the value when |
1589 |
+ |
it is null. This allows for alternative user defined setting of the generator |
1590 |
+ |
|
1591 |
+ |
Many thanks to Julio Jiménez for this fix |
1592 |
+ |
|
1593 |
+ |
2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library |
1594 |
+ |
and suggests that the user may have forgotten to install it. |
1595 |
+ |
|
1596 |

1. Conditional compilation used to limit registration of TIntegerField to |
1599 |
+ |
Lazarus versions less than 1.1 |
1600 |
+ |
|
1601 |
+ |
2. When a database connection is created, character set is now by default set |
1602 |
+ |
to UTF8 (Unix) or to the current Windows code page (Windows) if in the range |
1603 |
+ |
1250 to 1254. |

1612 |
+ |
|
1613 |
+ |
1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0 |
1614 |
+ |
Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1 |
1615 |
+ |
|
1616 |
+ |
2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB |
1617 |
+ |
package is changed to do this (which it should do). |
1618 |
+ |
|
1619 |
+ |
IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100 |
1620 |
+ |
|
1621 |
+ |
1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close). |
1622 |
+ |
|
1623 |
+ |
2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance) |
1624 |
+ |
|
1625 |
+ |
3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes |
1626 |
+ |
|
1627 |
+ |
4. Property editors should now correctly resize. |
1628 |
+ |
|
1629 |
+ |
5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox |
1630 |
+ |
(restored original functionality) |
1631 |
+ |
|
1632 |
+ |
6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird |
1633 |
+ |
library using the absolute path /Library/Frameworks/Firebird.framework/Firebird. |
