IBX Change Log version (2.3-5 Build 12341) Mon, 24 Aug 2020 10:23:35 +0100 |
2 |
+ |
|
3 |
+ |
1. TIBStringField: when a string value is read from a dataset buffer, if the |
4 |
+ |
number of UTF8 characters exceeds the string size then string is truncated |
5 |
+ |
to the maximum string size. This is usually a problem with fixed width columns |
6 |
+ |
right padded with white space. |
7 |
+ |
|
8 |
+ |
2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset. |
9 |
+ |
If SQLFiltered is set then when a dataset is opened, each line in the |
10 |
+ |
SQLFilterParams property is assumed to be a SQL condition clause and |
11 |
+ |
ANDed into the Where clause of the SQL Select statement provided as a |
12 |
+ |
dataset property. Each such SQL condition thus acts as an additional filter |
13 |
+ |
on the dataset. (Not yet tested) |
14 |
+ |
|
15 |
+ |
3. The Filtered property inherited from TDataset is no longer used for SQL (server |
16 |
+ |
side filters). |
17 |
+ |
|
18 |
+ |
4. IBLookupComboEditBox: Selection should no longer reset to start of text when |
19 |
+ |
text matches complete entry. |
20 |
+ |
|
21 |
+ |
5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail |
22 |
+ |
dataset are active (avoids risk of access violation if master is inactive) |
23 |
+ |
|
24 |
+ |
6. TIBEvents: Registered property can now be set at design time even if database not open |
25 |
+ |
|
26 |
+ |
7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents. |
27 |
+ |
This should prevent "spillover" of events between sessions. |
28 |
+ |
|
29 |
+ |
8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset. |
30 |
+ |
This should ensure that the internal buffer is set up correctly and avoids |
31 |
+ |
a duplicate initial row. |
32 |
+ |
|
33 |
+ |
9. TIBStringField: DataSize now given as byte size of string less trailing any zero character. |
34 |
+ |
That is, the DataSize should be the field size * character set width. The |
35 |
+ |
value returned by DataSize is now the same as the Dataset buffer size reserved |
36 |
+ |
for the field. |
37 |
+ |
|
38 |
+ |
10. IBExtact: Tidyup of SQL generation. Avoid unnecessary double quotes. |
39 |
+ |
|
40 |
+ |
11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer |
41 |
+ |
and vice-versa. This may result in an exception being raised (correctly) for |
42 |
+ |
older programs when using dataset fields added to a form and the database has been |
43 |
+ |
upgraded. For example, computed fields can change from 32-bit to 64-bit integers. |
44 |
+ |
In such cases, the field needs to be deleted in the IDE fields editor and then |
45 |
+ |
added back in. |
46 |
+ |
|
47 |
+ |
12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This |
48 |
+ |
should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit |
49 |
+ |
is cancelled. |
50 |
+ |
|
51 |
+ |
IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100 |
52 |
+ |
|
53 |
+ |
1. TIBXDataSet and Generators: Generator Names that are not all upper case or |
54 |
+ |
not SQL Identifiers are now supported. |
55 |
+ |
|
56 |
+ |
2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is |
57 |
+ |
passed to the Firebird engine for execution. |
58 |
+ |
|
59 |
+ |
3. TIBDataSet: Unidirectional datasets now give an error message if an attempt |
60 |
+ |
is made to scroll back. |
61 |
+ |
|
62 |
+ |
4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf |
63 |
+ |
|
64 |
+ |
5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now |
65 |
+ |
only enclosed in double quotes in SQL dialect 3 and when it needs to be. |
66 |
+ |
|
67 |
+ |
6. TIBLookupComboEditBox: when the list source opens, the ListField name is now |
68 |
+ |
validated. If no match is found in the list of field names and the database has |
69 |
+ |
been opened in SQL Dialect 3, then the ListField Name is converted to upper case |
70 |
+ |
if it then matches a field name. Otherwise, a Listfield not valid exception occurs. |
71 |
+ |
|
72 |
+ |
7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance |
73 |
+ |
with fpc 3.2. |
74 |
+ |
|
75 |
+ |
IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000 |
76 |
+ |
|
77 |
+ |
|
78 |
+ |
1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides" |
79 |
+ |
and is used to override the default settings in the client side "firebird.conf" This |
80 |
+ |
includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings". |
81 |
+ |
Each line of the string list should be a setting in the same format as "firebird.conf". |
82 |
+ |
For example "WireCompression = true" in order to request wire compression on the client side. |
83 |
+ |
|
84 |
+ |
Note: explicit settings in the client side "firebird.conf" appear to take precedence |
85 |
+ |
over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings |
86 |
+ |
also require a compatible setting in the server side "firebird.conf". For example |
87 |
+ |
"WireCompression = true" must also be set in the server's "firebird.conf" for wire |
88 |
+ |
compression to be used. |
89 |
+ |
|
90 |
+ |
Whether or not WireCompression or WireCrypt are in use can be checked using the information |
91 |
+ |
returned with the Client/Server protocol version. See ibx/examples/dbadmin and |
92 |
+ |
ibx/examples/dbinfo for examples of how to display this information. |
93 |
+ |
|
94 |
+ |
2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This |
95 |
+ |
is a "convenience" property. If set the "WireCompression=true" is added to the |
96 |
+ |
ConfigOverrides. If unchecked then this setting is removed. |
97 |
+ |
|
98 |
+ |
3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and |
99 |
+ |
not "INT64". |
100 |
+ |
|
101 |
+ |
4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut |
102 |
+ |
These are: |
103 |
+ |
property TimestampFormat: string; |
104 |
+ |
property DateFormat: string; |
105 |
+ |
property TimeFormat: string; |
106 |
+ |
|
107 |
+ |
Respectively, these provide the date time format templates for SQL types: TIMESTAMP, |
108 |
+ |
DATETIME and TIME. The format strings use the standard FPC date/time format |
109 |
+ |
characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html). |
110 |
+ |
|
111 |
+ |
If any of the above properties are set to an empty string, then the locale default |
112 |
+ |
is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the |
113 |
+ |
locale default is extended by appending '.zzz' to include milliseconds. |
114 |
+ |
|
115 |
+ |
TIBCSVDataOut by default sets these properties to the empty string, while the other |
116 |
+ |
two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively. |
117 |
+ |
|
118 |
+ |
5. New published property for TIBCSVDataOut: |
119 |
+ |
property QuoteStrings: boolean (default true) |
120 |
+ |
|
121 |
+ |
If false then strings are unquoted, otherwise, the QuoteChar property value is |
122 |
+ |
used to delimit each and every string in the output. |
123 |
+ |
|
124 |
+ |
6. New published properties for TIBCSVDataOut: |
125 |
+ |
property FieldSeparator: string; |
126 |
+ |
property HeaderSeparator: string; |
127 |
+ |
|
128 |
+ |
Respectively, these provide the separator character(s) used to separate fields |
129 |
+ |
in data and header rows. Both default to ','. |
130 |
+ |
|
131 |
+ |
7. New published properties for TIBCSVDataOut and TIBBlockFormatOut: |
132 |
+ |
TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object; |
133 |
+ |
property OnFormatTextString; |
134 |
+ |
|
135 |
+ |
This event handler can be used to process text strings before they are included |
136 |
+ |
in the output e.g. to replace unprintable characters with alternative strings. |
137 |
+ |
This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT. |
138 |
+ |
|
139 |
+ |
8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name. |
140 |
+ |
Uses "FindParam" if in order to find out if a parameter with a given name exists |
141 |
+ |
and without raising and exception if it does not. |
142 |
+ |
|
143 |
+ |
9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure |
144 |
+ |
consistency with SQL queries. |
145 |
+ |
|
146 |
+ |
10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery. |
147 |
+ |
When true, SQL statement parameter names are parsed case sensitive. Note for |
148 |
+ |
TIBDataSet only applies to Select query. |
149 |
+ |
|
150 |
+ |
11. IBEvents: removing a TIBEvent component from a form should no longer result in |
151 |
+ |
an IDE exception. |
152 |
+ |
|
153 |
+ |
12. LocalDBSupport: initial database creation should now work correctly |
154 |
+ |
when the schema source is an sql file. |
155 |
+ |
|
156 |
+ |
13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent" |
157 |
+ |
when defined, this handler will be called by the internal TIBXScript during |
158 |
+ |
initial database creation when the schema source is an sql file and may be used |
159 |
+ |
to provide a visual indication of progress in console mode. |
160 |
+ |
|
161 |
+ |
14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set |
162 |
+ |
to true while a new local database is being created and its schema populated. |
163 |
+ |
Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions |
164 |
+ |
when the database is disconnected/connected during the create DB procedure. |
165 |
+ |
|
166 |
+ |
15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement |
167 |
+ |
are now always ignored and replaced by the user name and password provided as |
168 |
+ |
the login parameters for the TIBDatabase referenced from the TIBXScript. The |
169 |
+ |
IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is |
170 |
+ |
completely ignored if this property is true. |
171 |
+ |
|
172 |
+ |
16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes |
173 |
+ |
to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise |
174 |
+ |
ImageIndex and SelectImageIndex values on AddNode. |
175 |
+ |
|
176 |
+ |
17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now |
177 |
+ |
read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share |
178 |
+ |
the same database connection. |
179 |
+ |
|
180 |
+ |
18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property. |
181 |
+ |
if provided, this should be an conditional SQL expression suitable for |
182 |
+ |
including in an SQL Select statement "where" clause. If non-empty and the |
183 |
+ |
"Filtered" property is true then the SQL expression provided as the value of |
184 |
+ |
the "Filter" property is "ANDed" with any existing condition statement |
185 |
+ |
in the SQL statement's "Where" clause. |
186 |
+ |
|
187 |
+ |
If the "Filter" property is set at run time, the "Filtered" property is true |
188 |
+ |
and the dataset is already open, then the dataset is closed and re-opened automatically. |
189 |
+ |
|
190 |
+ |
The "Filter" condition may include IBX style parameters. In which case, their |
191 |
+ |
value must be set by the dataset's "OnBeforeOpen" event handler. |
192 |
+ |
|
193 |
+ |
This is a public property for TIBDataSet and TIBQuery query and intended for |
194 |
+ |
use at run time. |
195 |
+ |
|
196 |
+ |
Note: The property is a published property of TIBTable. The TIBTable functionality |
197 |
+ |
is unaffected by this change. |
198 |
+ |

IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000 |
200 |
+ |
|
201 |
+ |
1. Remove need to check for IsMultiThread by providing access to GUI timers via |
202 |
+ |
IBGUIInterface. Note: master/detail delay timer does not apply to console |
203 |
+ |
mode apps. |
204 |
+ |
|
205 |
+ |
2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select |
206 |
+ |
statement. This avoids problems if "Execute Block" is used as the Query. |
207 |
+ |
|
208 |
+ |
3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the |
209 |
+ |
internal SQL tokeniser routines. |
210 |
+ |
|
211 |
+ |
4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse |
212 |
+ |
as a select statement, with or without CTEs. |
213 |
+ |
|
214 |
+ |
5. IBSQLParser: parser now recognises the "ROWS" clause. |
215 |
+ |
|
216 |
+ |
6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the |
217 |
+ |
internal SQL tokeniser routines. |
218 |
+ |
|
219 |
+ |
7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions |
220 |
+ |
being raised for valid set statements processed by a data formatter. |
221 |
+ |
|
222 |
+ |
8. New published property for TIBDatabase and TIBXServicesConnection. This is |
223 |
+ |
FirebirdLibraryPathName: string. If not empty it is used to explicitly specify |
224 |
+ |
the path of the Firebird Library used by the database/services connection. |
225 |
+ |
|
226 |
+ |
9. New read only public property for TIBDatabase and TIBXServicesConnection. This |
227 |
+ |
is FirebirdAPI and returns the IFirebirdAPI interface used by the database/ |
228 |
+ |
services connection. |
229 |
+ |
|
230 |
+ |
10.SQL Property editors now quote parameter names if "Quote identifier" is selected |
231 |
+ |
or param name is not a valid SQL identifier. |
232 |
+ |
|
233 |
+ |
11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive |
234 |
+ |
view of whether the text box should be editable when no DataSource is specified. |
235 |
+ |
TIBLookupComboEditBox has been updated to workaround this problem. As long as |
236 |
+ |
ReadOnly is false, the text box is editable when no DataSource is specified. |
237 |
+ |
|
238 |
+ |
12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of |
239 |
+ |
the FBLIB environment variable. If you do not want to permit this then you |
240 |
+ |
must modify the Register procedure in the design/IBDBReg.pas unit to remove |
241 |
+ |
this setting. |
242 |
+ |
|
243 |
+ |
IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100 |
244 |
+ |
|
245 |
+ |
1. IBCustomDataset: replace deprecated function ValidUTF8String with call to |
246 |
+ |
Utf8EscapeControlChars |
247 |
+ |
|
248 |
+ |
IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100 |
249 |
+ |
|
250 |
+ |
IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove |
251 |
+ |
all previous copies of the IBX source code tree before installing this release. |
252 |
+ |
|
253 |
+ |
The IBX packages used by most users have not changed, with one exception. The |
254 |
+ |
IBServices unit has been moved to the package iblegacyServices.lpk. To continue |
255 |
+ |
to use the IBServices unit in your applications, please add the iblegacyServices |
256 |
+ |
to the list of dependencies. To do this, open the Project Inspector and select |
257 |
+ |
Add->New Requirement and select "ibLegacyServices" from the list of available |
258 |
+ |
packages. |
259 |
+ |
|
260 |
+ |
1. New unit IBXServices. The IBXServices unit is a re-architectured update of |
261 |
+ |
the IBServices unit providing what is intended to be a clearer and easier to |
262 |
+ |
use set of IB Services components. See Chapter 10 of the IBX User Guide for |
263 |
+ |
more information and the guide to "Firebird Service Management Using IBX". |
264 |
+ |
As indicated above, the legacy services components are still available and |
265 |
+ |
provided in a separate package. There is no need to update working applications |
266 |
+ |
using the older versions except for an additional package dependency. |
267 |
+ |
|
268 |
+ |
2. The IBX packages and source code tree have been re-organised in an attempt to |
269 |
+ |
finally get rid of the "duplicate ppu" warnings. This re-organisation should |
270 |
+ |
not affect existing users. Section 2.3 of the IBX User Guide describes the |
271 |
+ |
new set of IBX packages. |
272 |
+ |
|
273 |
+ |
3. The ibx/examples/DBAdmin and the ibx/examples/services example have been |
274 |
+ |
updated to use the new Services API components. |
275 |
+ |
|
276 |
+ |
4. The iblocal package has been updated to use the new Services API components. |
277 |
+ |
|
278 |
+ |
5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of |
279 |
+ |
TIBXSecurityService. It had been wrongly classified in the previous version |
280 |
+ |
as a per database configuration item. It is global to a server and hence |
281 |
+ |
correctly positioned as part of the Security Package. In the DBAdmin example, |
282 |
+ |
the setting has moved to the mappings page. |
283 |
+ |
|
284 |
+ |
6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements |
285 |
+ |
are ignored. |
286 |
+ |
|
287 |
+ |
7. TIBDatabase: DropDatabase now ensures that all transactions have been properly |
288 |
+ |
closed before the database is dropped. Before and After Disconnect event handlers |
289 |
+ |
are also fired. |
290 |
+ |
|
291 |
+ |
8. TIBTransaction: OnStartTransaction event now fires every time the transaction |
292 |
+ |
is started and not just the first time. |
293 |
+ |
|
294 |
+ |
9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform |
295 |
+ |
depenendency with comp type. |
296 |
+ |
|
297 |
+ |
10. IBDataOutput: select query data output is now sent to stdout instead of stderr. |
298 |
+ |
|
299 |
+ |
11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName |
300 |
+ |
then this is recognised and not ignored. |
301 |
+ |
|
302 |
+ |
12. TIBDataSet, TIBQuery, TIBTable: additions: |
303 |
+ |
function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean; |
304 |
+ |
function GetPerfStatistics(var stats: TPerfCounters): boolean; |
305 |
+ |
property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics; |
306 |
+ |
|
307 |
+ |
GetRowsAffected returns the affected row counts from the last insert/update/delete |
308 |
+ |
if EnableStatistics = true then GetPerfStatistics returns the current stats |
309 |
+ |
counters for the select query. Note: stats accumulate after each fetch from |
310 |
+ |
the database. To get total query cost after open, call the "Last" method |
311 |
+ |
and then GetPerfStatistics. |
312 |
+ |
|
313 |
+ |
See ibx/examples/consolemode for an example of the use of GetPerfStatistics |
314 |
+ |
|
315 |
+ |
13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated |
316 |
+ |
in parenthesises. |
317 |
+ |
|
318 |
+ |
14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3 |
319 |
+ |
SQL identifiers are always delimited by double quotes. If false, then they are |
320 |
+ |
only delimited if the identifier is a reserved word, contains lower case or special |
321 |
+ |
characters. Set this property to true to retain previous behaviour. |
322 |
+ |
|
323 |
+ |
15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names |
324 |
+ |
are now inserted in double quotes if not Reserved Words or valid SQL Identifiers. |
325 |
+ |
|
326 |
+ |
16. TIBDataSet, TIBQuery, TIBTable: addition: |
327 |
+ |
property MasterDetailDelay: integer {defaults to zero} |
328 |
+ |
|
329 |
+ |
When non-zero and the dataset is a detail table referencing a master table |
330 |
+ |
through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery) |
331 |
+ |
then a synchronisation delay is added (in milliseconds) between the master |
332 |
+ |
row changing and the detail dataset being re-opened. If the master dataset |
333 |
+ |
is scrolled before the delay expires then the delay is reset. This can be used |
334 |
+ |
to avoid performance overheads when scrolling through a large master dataset. |
335 |
+ |
|
336 |
+ |
Note: uses fptimer and hence requires a thread manager. Under Linux the |
337 |
+ |
chreads unit must be included in your project. TTimer is not used in order |
338 |
+ |
to avoid an LCL dependency. Requires FPC 3.0.2 or later. |
339 |
+ |
|
340 |
+ |
17. TIBExtract: User role grants now excluded when etGrantsToUser not specified |
341 |
+ |
with Extract Option eoDatabase. |
342 |
+ |
|
343 |
+ |
18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428 |
344 |
+ |
When a deLayoutChanged event is reported on the ListSource dataset, the |
345 |
+ |
combobox text is updated. This allows a listsource (detail) to be in a Master/Detail |
346 |
+ |
relationship with the control's datasource (master). |
347 |
+ |
|
348 |
+ |
19. TIBExtract: Full BigInt value range now supported for Generators/Sequences. |
349 |
+ |
|
350 |
+ |
20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their |
351 |
+ |
stubs. Pedantic fix really, as procedures output in dependency order anyway. |
352 |
+ |
|
353 |
+ |
21. TIBExtract: Package Headers and Package Bodies are now included in the extracted |
354 |
+ |
DDL (Firebird 3 and later only). |
355 |
+ |
|
356 |
+ |
22. TIBLookupComboBox Autocomplete Fixes: |
357 |
+ |
i. Only appended text is now selected after autocomplete. |
358 |
+ |
ii. Uppercase keys no longer ignored for autocomplete. |
359 |
+ |
iii. Retain Prefix case is now honoured correctly. |
360 |
+ |
iv. When a DataSource is assigned, typing after autocomplete now extends prefix |
361 |
+ |
before autocomplete performed. i.e. behaviour now the same as when |
362 |
+ |
no DataSource assigned. |
363 |
+ |
|
364 |
+ |
23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring |
365 |
+ |
between SQL statements. |
366 |
+ |
|
367 |
+ |
24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then |
368 |
+ |
ObjectNames are converted to upper case before matching against metadata object |
369 |
+ |
names, unless the objectname is delimited by double quotes, in which case, the |
370 |
+ |
double quotes are removed and the remaining string is used (unmodified) to match |
371 |
+ |
against the metadata object name. |
372 |
+ |
|
373 |
+ |
If true then the ObjectName is used as is without modification and matched |
374 |
+ |
against the metadata object name. No attempt is made to remove double quotes. |
375 |
+ |
|
376 |
+ |
25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used |
377 |
+ |
with eoTrigger, these extract types can be used to select only Database Triggers, |
378 |
+ |
or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types. |
379 |
+ |
|
380 |
+ |
26. TIBXScript: If an exception occurs during the processing of a statement, the |
381 |
+ |
statement separate character is now reset to the default (';'). |
382 |
+ |
|
383 |
+ |
27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect. |
384 |
+ |
|
385 |
+ |
28. TIBXScript: Transaction is no longer automatically reactivated immediately processing |
386 |
+ |
a commit or reconnect statement and instead activated only when next SQL statement |
387 |
+ |
is executed. |
388 |
+ |
|
389 |
+ |
29. TIBSQL.HasField should no longer generate and exception when the field does not exist. |
390 |
+ |
|
391 |
+ |
30. TIBXScript: case insensitive regex now used when matching statements instead of |
392 |
+ |
converting statement to upper case. |
393 |
+ |
|
394 |
+ |
31. TIBExtract: metadata comments now supported. New published property |
395 |
+ |
IncludeMetaDataComments (default true). If true then metadata comments included |
396 |
+ |
in extracted DDL. New Extract Object member eoComments. This may be used with |
397 |
+ |
ExtractObject method to list all metadata comments. |
398 |
+ |
|
399 |
+ |
32. TIBExtract: ListObjectNames method added. |
400 |
+ |
|
401 |
+ |
33. Updated Database component editor to support additional connection string |
402 |
+ |
types. |
403 |
+ |
|

+ |
IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000 |
405 |
+ |
|
406 |
+ |
NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO |
407 |
+ |
AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS |
408 |
+ |
RELEASE. |
409 |
+ |
|
410 |
+ |
NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE. |
411 |
+ |
|
412 |
+ |
1. IBExtract: Identity columns - add additional check for null column for generator name. |
413 |
+ |
|
414 |
+ |
2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses. |
415 |
+ |
The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further |
416 |
+ |
information). However, this is also a very useful mechanism for returning updated computed by |
417 |
+ |
column values. Values returned as a result of executing an Insert or Update statement |
418 |
+ |
replace existing values in the current row for each corresponding column. |
419 |
+ |
|
420 |
+ |
Previously, if a dataset's select query included read only (computed by) fields then |
421 |
+ |
an automatic row refresh was performed after an insert or update query had been processed, |
422 |
+ |
irrespective of the setting of the "ForcedUpdates" property. This has changed such |
423 |
+ |
that an automatic refresh is no longer performed if an insert or update query contains |
424 |
+ |
a returning clause that updates one or more fields on the current row. A full row |
425 |
+ |
refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any |
426 |
+ |
field values and the select query contains read only fields. Use of Insert/update |
427 |
+ |
returning should be significantly more efficient than executing a refresh query. |
428 |
+ |
|
429 |
+ |
This behaviour change is intended to be backwards compatible and there should be no need to change |
430 |
+ |
existing programs, other than to improve performance by using the new capability. |
431 |
+ |
|
432 |
+ |
3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as |
433 |
+ |
they are called when the dataset row is being deleted, there is no value in |
434 |
+ |
updating the current record from the query result. Instead, a new event handler |
435 |
+ |
"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and |
436 |
+ |
an OnDeleteReturning event handler is provided then it is called with the IResults returned |
437 |
+ |
by the query. The event handler can then interrogate the query results and |
438 |
+ |
perform whatever action is necessary. For example to confirm, to the user, |
439 |
+ |
the deletion of a row with the returned values. |
440 |
+ |
|
441 |
+ |
4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for |
442 |
+ |
any Computed By or Identity Columns. The IBTables example has been updated to |
443 |
+ |
illustrate the computation of the employee Full Name on update. |
444 |
+ |
|
445 |
+ |
5. TIBTable: The GeneratorField property is now published. |
446 |
+ |
|
447 |
+ |
6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List. |
448 |
+ |
When InsertSQL is generated, the Identity columns are not included in the list of values to |
449 |
+ |
be inserted. A RETURNING clause is added to the insert statement to return the value of |
450 |
+ |
each Identity column after the insert is executed. |
451 |
+ |
|
452 |
+ |
7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |
453 |
+ |
Similarly Insert Property Editor now generates Insert SQL with Computed By fields in |
454 |
+ |
Insert..Returning clause. |
455 |
+ |
|
456 |
+ |
8. TIBGenerator: small performance improvement by not preparing query each time |
457 |
+ |
a new value is generated. |
458 |
+ |
|
459 |
+ |
9. TIBSQL: Free resources when transaction changed - ensures new transaction is used. |
460 |
+ |
|
461 |
+ |
10. Property editors will now sync table name to a System Table when "Include System |
462 |
+ |
Tables" is selected and the query is for a System Table. |
463 |
+ |
|
464 |
+ |
11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field |
465 |
+ |
values are no longer converted to milliseconds from TDateTime and then back again |
466 |
+ |
to TDateTime (the conversion to milliseconds is the default TDataset approach). |
467 |
+ |
|
468 |
+ |
12. Property Editors handling of Stored Procedures. |
469 |
+ |
* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and |
470 |
+ |
which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select |
471 |
+ |
query). |
472 |
+ |
* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2). |
473 |
+ |
|
474 |
+ |
13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName |
475 |
+ |
can be used to select a package. If non-empty, the stored procedure name is |
476 |
+ |
expected to be a stored procedure defined in the specified package and the |
477 |
+ |
generated SQL will be as required for a stored procedure located in a package. |
478 |
+ |
|
479 |
+ |
14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include |
480 |
+ |
a "Package Name" drop down box to allow selection of a Firebird 3 Package from |
481 |
+ |
which a stored procedure can be selected. With no package name selected, non-package |
482 |
+ |
stored procedures are listed. |
483 |
+ |
|
484 |
+ |
15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting |
485 |
+ |
for password on reconnect. |
486 |
+ |
|
487 |
+ |
16. TIBDatabase: use IAttachment for connection default character set id, code page |
488 |
+ |
and character set name. |
489 |
+ |
|
490 |
+ |
17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise |
491 |
+ |
DB info lookups" |
492 |
+ |
|
493 |
+ |
18. IBExtract: now supports DDL Triggers and Grants to DDL objects. |
494 |
+ |
|
495 |
+ |
19. Add a property Editor for TIBUpdate.RefreshSQL. |
496 |
+ |
|
497 |
+ |
20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input |
498 |
+ |
parameters. This stops an exception being raised when the field cannot be |
499 |
+ |
located in the record buffer. |
500 |
+ |
|
501 |
+ |
21. Property Editors now automatically include System Tables when opened and when the query table |
502 |
+ |
is a System Table. |
503 |
+ |
|
504 |
+ |
22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception. |
505 |
+ |
This avoids errors due to a stale SQRB or SRB being used for the next query. |
506 |
+ |
|
507 |
+ |
23. IBServices: Service attach parameters now include "expected_db". This is used to |
508 |
+ |
add the SPB item isc_spb_expected_db. This names a database using |
509 |
+ |
an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a |
510 |
+ |
database. examples/services re-written to illustrate use of "expected_db". |
511 |
+ |
|
512 |
+ |
24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout. |
513 |
+ |
This avoids truncated backups when the server returns a timeout (busy) response. |
514 |
+ |
|
515 |
+ |
25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase. |
516 |
+ |
|
517 |
+ |
26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local |
518 |
+ |
databasenames. These are respectively expanded to the local system's temp directory |
519 |
+ |
(including trailing delimiter) or to a prescribed data directory (including |
520 |
+ |
trailing delimiter). Under Unix systems the data directory is a hidden directory |
521 |
+ |
in the user's home directory. The hidden directory name is either the string returned |
522 |
+ |
from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'. |
523 |
+ |
Under Windows, the directory is the same as the Data Directory as decribed |
524 |
+ |
above but instead prefixed by the User's application data path. These may be |
525 |
+ |
used to improve application portability for Personal Databases. |
526 |
+ |
|
527 |
+ |
27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef |
528 |
+ |
this has not worked for a long time and is not useful either. FieldDefs should be |
529 |
+ |
managed using the Fields Editor as with any other dataset. To access the fields |
530 |
+ |
editor for a TIBTable component, double click on the component. The fields editor |
531 |
+ |
is then displayed. |
532 |
+ |
|
533 |
+ |
28. TIBDatabaseInfo: new properties/function |
534 |
+ |
* DateDBCreated (returns date/time database created) |
535 |
+ |
* TransactionCount (returns no. of active transactions) |
536 |
+ |
* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only). |
537 |
+ |
* PagesFree (Firebird 3 or later) |
538 |
+ |
* PagesUsed (Firebird 3 or later) |
539 |
+ |
* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only) |
540 |
+ |
* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only) |
541 |
+ |
|
542 |
+ |
29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo. |
543 |
+ |
|
544 |
+ |
30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later). |
545 |
+ |
|
546 |
+ |
31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable |
547 |
+ |
the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later). |
548 |
+ |
|
549 |
+ |
32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced |
550 |
+ |
in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from |
551 |
+ |
firing during backup and restore. |
552 |
+ |
|
553 |
+ |
33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options |
554 |
+ |
for verbose output using the new property "StatisticsRequested". |
555 |
+ |
see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats |
556 |
+ |
|
557 |
+ |
34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later). |
558 |
+ |
|
559 |
+ |
35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin" |
560 |
+ |
palette. This uses the online validation feature added in Firebird 2.5. The |
561 |
+ |
services's properties enable inclusion/exclusion of tables and indexes using |
562 |
+ |
regular expressions. See. |
563 |
+ |
https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation |
564 |
+ |
|
565 |
+ |
36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger |
566 |
+ |
option on a database. |
567 |
+ |
|
568 |
+ |
37. TIBCustomService: Assign method implemented to allow copying of service login |
569 |
+ |
context between service API components. "Detach" method now only detaches |
570 |
+ |
service when last reference to the service interface detaches. Tidy up of |
571 |
+ |
code for SetActive and Attach methods including password hiding. |
572 |
+ |
|
573 |
+ |
38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only |
574 |
+ |
and used to determine the auth method and protocol used for the connection. |
575 |
+ |
|
576 |
+ |
39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using |
577 |
+ |
a Create Database Statement generated by IBX. |
578 |
+ |
|
579 |
+ |
40. All IBServices now have an additional published property "PortNo". This may |
580 |
+ |
be set to a non-standard port number when necessary. If zero then the default |
581 |
+ |
port number is used. |
582 |
+ |
|
583 |
+ |
41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard |
584 |
+ |
and not just the mouse. |
585 |
+ |
|
586 |
+ |
42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added. |
587 |
+ |
|
588 |
+ |
43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the |
589 |
+ |
image index and selected image index for each node to be set from a database field. |
590 |
+ |
|
591 |
+ |
44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included |
592 |
+ |
then database schema includes grants to all users. If not present then the |
593 |
+ |
only user grants included are those to User PUBLIC. |
594 |
+ |
|
595 |
+ |
45. TIBTreeView: performance improvement. When expanding include both expanded node |
596 |
+ |
and child nodes in dataset. |
597 |
+ |
|
598 |
+ |
|
599 |
+ |
IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000 |
600 |
+ |
|
601 |
+ |
1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf |
602 |
+ |
changes. |
603 |
+ |
|
604 |
+ |
2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString. |
605 |
+ |
Bug could result in truncated multi-byte character set values. |
606 |
+ |
|
607 |
+ |
3. Changes consequential on moving fbintf character set utility functions from |
608 |
+ |
IFirebirdAPI to IAttachment. |
609 |
+ |
|
610 |
+ |
4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true |
611 |
+ |
|
612 |
+ |
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally |
613 |
+ |
results in autocomplete ignoring prefix text. |
614 |
+ |
|
615 |
+ |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when |
616 |
+ |
entering a new name into the text box. |
617 |
+ |
|
618 |
+ |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by |
619 |
+ |
Firebird rather than recomputing it. |
620 |
+ |
|
621 |
+ |
8. Property Editor positioning tidy up: All IBX Property editors should now be |
622 |
+ |
screen centre. Previously some were "poDesigned" which may be inappropriate |
623 |
+ |
for multi monitor desktops. |
624 |
+ |
|
625 |
+ |
10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. |
626 |
+ |
|
627 |
+ |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending |
628 |
+ |
a transaction and always reset the object. |
629 |
+ |
|
630 |
+ |
12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows. |
631 |
+ |
|
632 |
+ |
13. TIBXScript: Allow for override of database filename in Create Database statements. |
633 |
+ |
|
634 |
+ |
14. IBLocaldb: Support initialisation of the database from an SQL script in addition |
635 |
+ |
to a gbak format archive. |
636 |
+ |
|
637 |
+ |
15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised. |
638 |
+ |
|
639 |
+ |
16. IBLocaldb: Drop database if error creating an empty database. |
640 |
+ |
|
641 |
+ |
17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset |
642 |
+ |
unless selected node not in current dataset. |
643 |
+ |
|
644 |
+ |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) |
645 |
+ |
to TIBCustomService, and IBlocalDB code tidy up. |
646 |
+ |
|
647 |
+ |
19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable |
648 |
+ |
behaviour due to uninitialised variable. |
649 |
+ |
|
650 |
+ |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from |
651 |
+ |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. |
652 |
+ |
|
653 |
+ |
21. IBSQL: When Database changed ensure that all resources are freed. |
654 |
+ |
|
655 |
+ |
22. IBCustomDataset: When database changed ensure that queries an unprepared. |
656 |
+ |
|
657 |
+ |
23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include: |
658 |
+ |
* Line Wrap on SQL Token boundaries (on user command) |
659 |
+ |
* auto-complete table names in drop down list of table names |
660 |
+ |
* Double click on tablename or field name adds to SQL text |
661 |
+ |
|
662 |
+ |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). |
663 |
+ |
|
664 |
+ |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to |
665 |
+ |
TVariantArray. Seems to avoid memory corruption in Windows (probably a |
666 |
+ |
workaround for a problem in fpc 3.0.4 win64). |
667 |
+ |
|
668 |
+ |
26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open. |
669 |
+ |
|
670 |
+ |
27. IBDatabaseInfo: Remove memory leak when accessing database operation counts. |

IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000 |
673 |
+ |
|
674 |
+ |
1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to |
675 |
+ |
include remote system name. |
676 |
+ |
|
677 |
+ |
2. TIBExtract: No longer include comment header and COMMIT statement for empty |
678 |
+ |
tables when data included in output. |
679 |
+ |
|
680 |
+ |
3. Profiling: IBSQL now has conditional compilation flags to enable query performance |
681 |
+ |
and timing information to be written to stdout. This may be used to locate |
682 |
+ |
performance bottlenecks. |
683 |
+ |
|
684 |
+ |
4. SQLParser: only call "OnChanging" event handler when value is different. |
685 |
+ |
|
686 |
+ |
5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit |
687 |
+ |
|
688 |
+ |
6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures |
689 |
+ |
that BindFields is called when the query is next activated. Avoids FieldName |
690 |
+ |
not found error. |
691 |
+ |
|
692 |
+ |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general |
693 |
+ |
purpose and allows the programmer to define any action they want for Update, Insert |
694 |
+ |
or Delete. This may be complex SQL (similar to a Trigger), application specific |
695 |
+ |
filtering of updates, or use of statements such as Grant or Revoke instead of |
696 |
+ |
normal DML. See User Manual for more information. |

699 |
+ |
|
700 |
+ |
1. TIBEvents: Fix uninitialised variable that could result in lost events. |
701 |
+ |
|
702 |
+ |
2. TIBExtract: Added support for FB3 "USAGE" privilege. |
703 |
+ |
|
704 |
+ |
3. TIBExtract: data formatted as Charset set "octets" is now output using |
705 |
+ |
hexadecimal notation. |
706 |
+ |
|
707 |
+ |
4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements |
708 |
+ |
using a simple XML format. |
709 |
+ |
|
710 |
+ |
5. TIBExtract: extract of individual Triggers and Stored Procedures can now include |
711 |
+ |
grants to these objects. |
712 |
+ |
|
713 |
+ |
6. TIBExtract: Stored Procedures and Views output in dependency order to avoid |
714 |
+ |
dependency problems restoring complex databases. |
715 |
+ |
|
716 |
+ |
7. TIBXScript: This component has been restructured to allow for the processing of |
717 |
+ |
embedded XML in INSERT statements and to support interactive sources in addition |
718 |
+ |
to non-interactive data sources such as files. |
719 |
+ |
|
720 |
+ |
8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported. |
721 |
+ |
|
722 |
+ |
9. TIBXScript: ISQL compatiable Set statements are now supported: |
723 |
+ |
SET SQL DIALECT |
724 |
+ |
SET TERM |
725 |
+ |
SET AUTODDL |
726 |
+ |
SET BAIL |
727 |
+ |
SET ECHO |
728 |
+ |
SET COUNT |
729 |
+ |
SET STATS |
730 |
+ |
SET NAMES <character set> |
731 |
+ |
|
732 |
+ |
10. IBVersion unit added to hold current IBX Version Number information. |
733 |
+ |
|
734 |
+ |
11. TIBExtract: Use character rather than byte length for VarChar procedure arguments., |
735 |
+ |
and domain definitions. |
736 |
+ |
|
737 |
+ |
12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers |
738 |
+ |
fully supported. |
739 |
+ |
|
740 |
+ |
13. TIBExtract: when a database dump includes data, the generator values are now also set. |
741 |
+ |
|
742 |
+ |
14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later. |
743 |

745 |
+ |
|
746 |
+ |
See also doc/IBX4LazarusGuide.pdf for important information on |
747 |
+ |
upgrading to IBX2. |
748 |
+ |
|
749 |
+ |
1. Size property of TIBStringField is now the width in characters of the field |
750 |
+ |
and not the byte length. This applies only to multi-byte character sets such |
751 |
+ |
as UTF8. The original approach aligned with TStringField. However, the TStringField |
752 |
+ |
code is not recognised as a bug and hence this change to align the behaviour. |
753 |
+ |
The TStringField change is expected in fpc 3.2.0. |
754 |
+ |
|
755 |
+ |
2. A new property AutoFieldSize: boolean has been added to TIBStringField. When |
756 |
+ |
true (default) then Size property value saved in the lfm is ignored. Size is |
757 |
+ |
always set from the dynamic information read from the database. It is unclear |
758 |
+ |
why anyone would want to override this and set Size to false. |
759 |
+ |
|
760 |
+ |
3. ibxscript: should now handle correctly a Case..End statement within a procedure |
761 |
+ |
block. |
762 |
+ |
|
763 |
+ |
4. IBDatabase: new property - CreateIfNotExists. If true and database does not |
764 |
+ |
exist when an attempt is made to connect to it (run time only) then an attempt |
765 |
+ |
is made to create the database. |
766 |
+ |
|
767 |
+ |
5. IBDatabase: new event - OnCreateDatabase. This event is called after a database |
768 |
+ |
has been successfully created as a result of a call to CreateDatabase or when |
769 |
+ |
creating a database after it was found not to exist. |
770 |
+ |
|
771 |
+ |
6. DBControlGrid: a race condition could result in the wrong row image being |
772 |
+ |
written to the cache. This has been avoided by a trip round the message |
773 |
+ |
loop before rendering the row image. |
774 |
+ |
|
775 |
+ |
7. DBControlGrid: It is strongly recommended not to open the source DataSet for |
776 |
+ |
a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is |
777 |
+ |
known to risk corrupt rendering of row images when the control is first |
778 |
+ |
displayed. If necessary use "Application.QueueAsyncCall" to delay opening |
779 |
+ |
of the dataset (see DBControlGrid examples) until the Form's Window has been created. |
780 |
+ |
|
781 |
+ |
8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with |
782 |
+ |
a TDateEdit control located on an editor panel. |
783 |
+ |
|
784 |
+ |
9. TIBExtract: brought up-to-date plus many bug fixes. |
785 |
+ |
|
786 |
+ |
10. DBControlGrid: Removed memory leak when updating rows. |
787 |
+ |
|
788 |
+ |
11. TIBCMLocalDBSupport: fixed invalid free on upgrade. |
789 |
+ |

|
1. IBCustomDataset: When calling SetCodePage, no longer request transliteration |
808 |
|
regardless of the database character set or connection character set. This |
809 |
|
is for compatibility with the LCL. |

1. IBBlob: Defer reading of blob until read method called. This avoids having to |
814 |
|
read in an entire blob just to get the size of the blob. General performance |
