IBX Change Log version (2.3-0) Fri, 16 Mar 2018 10:25:25 +0000 |
2 |
> |
|
3 |
> |
IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove |
4 |
> |
all previous copies of the IBX source code tree before installing this release. |
5 |
> |
|
6 |
> |
The IBX packages used by most users have not changed, with one exception. The |
7 |
> |
IBServices unit has been moved to the package iblegacyServices.lpk. To continue |
8 |
> |
to use the IBServices unit in your applications, please add the iblegacyServices |
9 |
> |
to the list of dependencies. To do this, open the Project Inspector and select |
10 |
> |
Add->New Requirement and select "ibLegacyServices" from the list of available |
11 |
> |
packages. |
12 |
> |
|
13 |
> |
1. New unit IBXServices. The IBXServices unit is a re-architectured update of |
14 |
> |
the IBServices unit providing what is intended to be a clearer and easier to |
15 |
> |
use set of IB Services components. See Chapter 10 of the IBX User Guide for |
16 |
> |
more information and the guide to "Firebird Service Management Using IBX". |
17 |
> |
As indicated above, the legacy services components are still available and |
18 |
> |
provided in a separate package. There is no need to update working applications |
19 |
> |
using the older versions except for an additional package dependency. |
20 |
> |
|
21 |
> |
2. The IBX packages and source code tree have been re-organised in an attempt to |
22 |
> |
finally get rid of the "duplicate ppu" warnings. This re-organisation should |
23 |
> |
not affect existing users. Section 2.3 of the IBX User Guide describes the |
24 |
> |
new set of IBX packages. |
25 |
> |
|
26 |
> |
3. The ibx/examples/DBAdmin and the ibx/examples/services example have been |
27 |
> |
updated to use the new Services API components. |
28 |
> |
|
29 |
> |
4. The iblocal package has been updated to use the new Services API components. |
30 |
> |
|
31 |
> |
5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of |
32 |
> |
TIBXSecurityService. It had been wrongly classified in the previous version |
33 |
> |
as a per database configuration item. It is global to a server and hence |
34 |
> |
correctly positioned as part of the Security Package. In the DBAdmin example, |
35 |
> |
the setting has moved to the mappings page. |
36 |
> |
|
37 |
> |
6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements |
38 |
> |
are ignored. |
39 |
> |
|
40 |
> |
7. TIBDatabase: DropDatabase now ensures that all transactions have been properly |
41 |
> |
closed before the database is dropped. Before and After Disconnect event handlers |
42 |
> |
are also fired. |
43 |
> |
|
44 |
> |
8. TIBTransaction: OnStartTransaction event now fires every time the transaction |
45 |
> |
is started and not just the first time. |
46 |
> |
|
47 |
> |
9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform |
48 |
> |
depenendency with comp type. |
49 |
> |
|
50 |
> |
10. IBDataOutput: select query data output is now sent to stdout instead of stderr. |
51 |
> |
|
52 |
> |
11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName |
53 |
> |
then this is recognised and not ignored. |
54 |
> |
|
55 |
> |
12. TIBDataSet, TIBQuery, TIBTable: additions: |
56 |
> |
function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean; |
57 |
> |
function GetPerfStatistics(var stats: TPerfCounters): boolean; |
58 |
> |
property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics; |
59 |
> |
|
60 |
> |
GetRowsAffected returns the affected row counts from the last insert/update/delete |
61 |
> |
if EnableStatistics = true then GetPerfStatistics returns the current stats |
62 |
> |
counters for the select query. Note: stats accumulate after each fetch from |
63 |
> |
the database. To get total query cost after open, call the "Last" method |
64 |
> |
and then GetPerfStatistics. |
65 |
> |
|
66 |
> |
See ibx/examples/consolemode for an example of the use of GetPerfStatistics |
67 |
> |
|
68 |
> |
13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated |
69 |
> |
in parenthesises. |
70 |
> |
|
71 |
> |
14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3 |
72 |
> |
SQL identifiers are always delimited by double quotes. If false, then they are |
73 |
> |
only delimited if the identifier is a reserved word, contains lower case or special |
74 |
> |
characters. Set this property to true to retain previous behaviour. |
75 |
> |
|
76 |
> |
15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names |
77 |
> |
are now inserted in double quotes if not Reserved Words or valid SQL Identifiers. |
78 |
> |
|
79 |
> |
16. TIBDataSet, TIBQuery, TIBTable: addition: |
80 |
> |
property MasterDetailDelay: integer {defaults to zero} |
81 |
> |
|
82 |
> |
When non-zero and the dataset is a detail table referencing a master table |
83 |
> |
through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery) |
84 |
> |
then a synchronisation delay is added (in milliseconds) between the master |
85 |
> |
row changing and the detail dataset being re-opened. If the master dataset |
86 |
> |
is scrolled before the delay expires then the delay is reset. This can be used |
87 |
> |
to avoid performance overheads when scrolling through a large master dataset. |
88 |
> |
|
89 |
> |
Note: uses fptimer and hence requires a thread manager. Under Linux the |
90 |
> |
chreads unit must be included in your project. TTimer is not used in order |
91 |
> |
to avoid an LCL dependency. Requires FPC 3.0.2 or later. |
92 |
> |
|
93 |
> |
17. TIBExtract: User role grants now excluded when etGrantsToUser not specified |
94 |
> |
with Extract Option eoDatabase. |
95 |
> |
|
96 |
> |
18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428 |
97 |
> |
When a deLaoutChanged event is reported on the ListSource dataset, the |
98 |
> |
combobox text is updated. This allows a listsource (detail) to be in a Master/Detail |
99 |
> |
relationship with the control's datasource (master). |
100 |

IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000 |
102 |
> |
|
103 |
> |
NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO |
104 |
> |
AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS |
105 |
> |
RELEASE. |
106 |
> |
|
107 |
> |
NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE. |
108 |
> |
|
109 |
> |
1. IBExtract: Identity columns - add additional check for null column for generator name. |
110 |
> |
|
111 |
> |
2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses. |
112 |
> |
The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further |
113 |
> |
information). However, this is also a very useful mechanism for returning updated computed by |
114 |
> |
column values. Values returned as a result of executing an Insert or Update statement |
115 |
> |
replace existing values in the current row for each corresponding column. |
116 |
> |
|
117 |
> |
Previously, if a dataset's select query included read only (computed by) fields then |
118 |
> |
an automatic row refresh was performed after an insert or update query had been processed, |
119 |
> |
irrespective of the setting of the "ForcedUpdates" property. This has changed such |
120 |
> |
that an automatic refresh is no longer performed if an insert or update query contains |
121 |
> |
a returning clause that updates one or more fields on the current row. A full row |
122 |
> |
refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any |
123 |
> |
field values and the select query contains read only fields. Use of Insert/update |
124 |
> |
returning should be significantly more efficient than executing a refresh query. |
125 |
> |
|
126 |
> |
This behaviour change is intended to be backwards compatible and there should be no need to change |
127 |
> |
existing programs, other than to improve performance by using the new capability. |
128 |
> |
|
129 |
> |
3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as |
130 |
> |
they are called when the dataset row is being deleted, there is no value in |
131 |
> |
updating the current record from the query result. Instead, a new event handler |
132 |
> |
"OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and |
133 |
> |
an OnDeleteReturning event handler is provided then it is called with the IResults returned |
134 |
> |
by the query. The event handler can then interrogate the query results and |
135 |
> |
perform whatever action is necessary. For example to confirm, to the user, |
136 |
> |
the deletion of a row with the returned values. |
137 |
> |
|
138 |
> |
4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for |
139 |
> |
any Computed By or Identity Columns. The IBTables example has been updated to |
140 |
> |
illustrate the computation of the employee Full Name on update. |
141 |
> |
|
142 |
> |
5. TIBTable: The GeneratorField property is now published. |
143 |
> |
|
144 |
> |
6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List. |
145 |
> |
When InsertSQL is generated, the Identity columns are not included in the list of values to |
146 |
> |
be inserted. A RETURNING clause is added to the insert statement to return the value of |
147 |
> |
each Identity column after the insert is executed. |
148 |
> |
|
149 |
> |
7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. |
150 |
> |
Similarly Insert Property Editor now generates Insert SQL with Computed By fields in |
151 |
> |
Insert..Returning clause. |
152 |
> |
|
153 |
> |
8. TIBGenerator: small performance improvement by not preparing query each time |
154 |
> |
a new value is generated. |
155 |
> |
|
156 |
> |
9. TIBSQL: Free resources when transaction changed - ensures new transaction is used. |
157 |
> |
|
158 |
> |
10. Property editors will now sync table name to a System Table when "Include System |
159 |
> |
Tables" is selected and the query is for a System Table. |
160 |
> |
|
161 |
> |
11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field |
162 |
> |
values are no longer converted to milliseconds from TDateTime and then back again |
163 |
> |
to TDateTime (the conversion to milliseconds is the default TDataset approach). |
164 |
> |
|
165 |
> |
12. Property Editors handling of Stored Procedures. |
166 |
> |
* Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and |
167 |
> |
which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select |
168 |
> |
query). |
169 |
> |
* Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2). |
170 |
> |
|
171 |
> |
13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName |
172 |
> |
can be used to select a package. If non-empty, the stored procedure name is |
173 |
> |
expected to be a stored procedure defined in the specified package and the |
174 |
> |
generated SQL will be as required for a stored procedure located in a package. |
175 |
> |
|
176 |
> |
14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include |
177 |
> |
a "Package Name" drop down box to allow selection of a Firebird 3 Package from |
178 |
> |
which a stored procedure can be selected. With no package name selected, non-package |
179 |
> |
stored procedures are listed. |
180 |
> |
|
181 |
> |
15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting |
182 |
> |
for password on reconnect. |
183 |
> |
|
184 |
> |
16. TIBDatabase: use IAttachment for connection default character set id, code page |
185 |
> |
and character set name. |
186 |
> |
|
187 |
> |
17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise |
188 |
> |
DB info lookups" |
189 |
> |
|
190 |
> |
18. IBExtract: now supports DDL Triggers and Grants to DDL objects. |
191 |
> |
|
192 |
> |
19. Add a property Editor for TIBUpdate.RefreshSQL. |
193 |
> |
|
194 |
> |
20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input |
195 |
> |
parameters. This stops an exception being raised when the field cannot be |
196 |
> |
located in the record buffer. |
197 |
> |
|
198 |
> |
21. Property Editors now automatically include System Tables when opened and when the query table |
199 |
> |
is a System Table. |
200 |
> |
|
201 |
> |
22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception. |
202 |
> |
This avoids errors due to a stale SQRB or SRB being used for the next query. |
203 |
> |
|
204 |
> |
23. IBServices: Service attach parameters now include "expected_db". This is used to |
205 |
> |
add the SPB item isc_spb_expected_db. This names a database using |
206 |
> |
an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a |
207 |
> |
database. examples/services re-written to illustrate use of "expected_db". |
208 |
> |
|
209 |
> |
24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout. |
210 |
> |
This avoids truncated backups when the server returns a timeout (busy) response. |
211 |
> |
|
212 |
> |
25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase. |
213 |
> |
|
214 |
> |
26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local |
215 |
> |
databasenames. These are respectively expanded to the local system's temp directory |
216 |
> |
(including trailing delimiter) or to a prescribed data directory (including |
217 |
> |
trailing delimiter). Under Unix systems the data directory is a hidden directory |
218 |
> |
in the user's home directory. The hidden directory name is either the string returned |
219 |
> |
from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'. |
220 |
> |
Under Windows, the directory is the same as the Data Directory as decribed |
221 |
> |
above but instead prefixed by the User's application data path. These may be |
222 |
> |
used to improve application portability for Personal Databases. |
223 |
> |
|
224 |
> |
27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef |
225 |
> |
this has not worked for a long time and is not useful either. FieldDefs should be |
226 |
> |
managed using the Fields Editor as with any other dataset. To access the fields |
227 |
> |
editor for a TIBTable component, double click on the component. The fields editor |
228 |
> |
is then displayed. |
229 |
> |
|
230 |
> |
28. TIBDatabaseInfo: new properties/function |
231 |
> |
* DateDBCreated (returns date/time database created) |
232 |
> |
* TransactionCount (returns no. of active transactions) |
233 |
> |
* GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only). |
234 |
> |
* PagesFree (Firebird 3 or later) |
235 |
> |
* PagesUsed (Firebird 3 or later) |
236 |
> |
* Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only) |
237 |
> |
* EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only) |
238 |
> |
|
239 |
> |
29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo. |
240 |
> |
|
241 |
> |
30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later). |
242 |
> |
|
243 |
> |
31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable |
244 |
> |
the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later). |
245 |
> |
|
246 |
> |
32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced |
247 |
> |
in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from |
248 |
> |
firing during backup and restore. |
249 |
> |
|
250 |
> |
33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options |
251 |
> |
for verbose output using the new property "StatisticsRequested". |
252 |
> |
see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats |
253 |
> |
|
254 |
> |
34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later). |
255 |
> |
|
256 |
> |
35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin" |
257 |
> |
palette. This uses the online validation feature added in Firebird 2.5. The |
258 |
> |
services's properties enable inclusion/exclusion of tables and indexes using |
259 |
> |
regular expressions. See. |
260 |
> |
https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation |
261 |
> |
|
262 |
> |
36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger |
263 |
> |
option on a database. |
264 |
> |
|
265 |
> |
37. TIBCustomService: Assign method implemented to allow copying of service login |
266 |
> |
context between service API components. "Detach" method now only detaches |
267 |
> |
service when last reference to the service interface detaches. Tidy up of |
268 |
> |
code for SetActive and Attach methods including password hiding. |
269 |
> |
|
270 |
> |
38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only |
271 |
> |
and used to determine the auth method and protocol used for the connection. |
272 |
> |
|
273 |
> |
39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using |
274 |
> |
a Create Database Statement generated by IBX. |
275 |
> |
|
276 |
> |
40. All IBServices now have an additional published property "PortNo". This may |
277 |
> |
be set to a non-standard port number when necessary. If zero then the default |
278 |
> |
port number is used. |
279 |
> |
|
280 |
> |
41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard |
281 |
> |
and not just the mouse. |
282 |
> |
|
283 |
> |
42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added. |
284 |
> |
|
285 |
> |
43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the |
286 |
> |
image index and selected image index for each node to be set from a database field. |
287 |
> |
|
288 |
> |
44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included |
289 |
> |
then database schema includes grants to all users. If not present then the |
290 |
> |
only user grants included are those to User PUBLIC. |
291 |
> |
|
292 |
> |
45. TIBTreeView: performance improvement. When expanding include both expanded node |
293 |
> |
and child nodes in dataset. |

IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000 |
297 |
> |
|
298 |
> |
1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf |
299 |
> |
changes. |
300 |
> |
|
301 |
> |
2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString. |
302 |
> |
Bug could result in truncated multi-byte character set values. |
303 |
> |
|
304 |
> |
3. Changes consequential on moving fbintf character set utility functions from |
305 |
> |
IFirebirdAPI to IAttachment. |
306 |
> |
|
307 |
> |
4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true |
308 |
> |
|
309 |
> |
5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally |
310 |
> |
results in autocomplete ignoring prefix text. |
311 |
> |
|
312 |
> |
6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when |
313 |
> |
entering a new name into the text box. |
314 |
> |
|
315 |
> |
7. IBCustomDataset: ensure that TIBStringField uses the field size reported by |
316 |
> |
Firebird rather than recomputing it. |
317 |
> |
|

screen centre. Previously some were "poDesigned" which may be inappropriate |
320 |
> |
for multi monitor desktops. |
321 |
> |
|
322 |

10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. |
323 |
> |
|
324 |
> |
11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending |
325 |

|
327 |
> |
12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows. |
328 |

|
336 |
> |
16. IBLocaldb: Drop database if error creating an empty database. |
337 |

17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset |
339 |
> |
unless selected node not in current dataset. |
340 |
> |
|
341 |
> |
18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) |
342 |
> |
to TIBCustomService, and IBlocalDB code tidy up. |
343 |
> |
|
344 |

19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable |
345 |
> |
behaviour due to uninitialised variable. |
346 |
> |
|
347 |
> |
20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from |
348 |
> |
integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. |
349 |
> |
|
350 |
> |
21. IBSQL: When Database changed ensure that all resources are freed. |
351 |
> |
|
352 |
> |
22. IBCustomDataset: When database changed ensure that queries an unprepared. |
353 |
> |
|
354 |

23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include: |
355 |
> |
* Line Wrap on SQL Token boundaries (on user command) |
356 |
> |
* auto-complete table names in drop down list of table names |
357 |

> |
24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). |
360 |
> |
|
361 |
> |
25. IBTreeView: Call to FindNode: param type change from "array of Variant" to |
362 |
> |
TVariantArray. Seems to avoid memory corruption in Windows (probably a |
363 |

370 |
> |
|
371 |
> |
1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to |
372 |
> |
include remote system name. |
373 |
> |
|
374 |
> |
2. TIBExtract: No longer include comment header and COMMIT statement for empty |
375 |
> |
tables when data included in output. |
376 |
> |
|
377 |
> |
3. Profiling: IBSQL now has conditional compilation flags to enable query performance |
378 |
> |
and timing information to be written to stdout. This may be used to locate |
379 |
> |
performance bottlenecks. |
380 |
> |
|
381 |
> |
4. SQLParser: only call "OnChanging" event handler when value is different. |
382 |
> |
|
383 |
> |
5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit |
384 |
> |
|
385 |
> |
6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures |
386 |
> |
that BindFields is called when the query is next activated. Avoids FieldName |
387 |
> |
not found error. |
388 |
> |
|
389 |
> |
7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general |
390 |
> |
purpose and allows the programmer to define any action they want for Update, Insert |
391 |
> |
or Delete. This may be complex SQL (similar to a Trigger), application specific |
392 |
> |
filtering of updates, or use of statements such as Grant or Revoke instead of |
393 |
> |
normal DML. See User Manual for more information. |

|
399 |
> |
2. TIBExtract: Added support for FB3 "USAGE" privilege. |
400 |
> |
|
401 |

3. TIBExtract: data formatted as Charset set "octets" is now output using |
402 |
> |
hexadecimal notation. |
403 |
> |
|
404 |
> |
4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements |
405 |
> |
using a simple XML format. |
406 |
> |
|
407 |
> |
5. TIBExtract: extract of individual Triggers and Stored Procedures can now include |
408 |
> |
grants to these objects. |
409 |
> |
|
410 |
> |
6. TIBExtract: Stored Procedures and Views output in dependency order to avoid |
411 |
> |
dependency problems restoring complex databases. |
412 |
> |
|
413 |
> |
7. TIBXScript: This component has been restructured to allow for the processing of |
414 |
> |
embedded XML in INSERT statements and to support interactive sources in addition |
415 |
> |
to non-interactive data sources such as files. |
416 |
> |
|
417 |
> |
8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported. |
418 |
> |
|
419 |
> |
9. TIBXScript: ISQL compatiable Set statements are now supported: |
420 |

SET SQL DIALECT |
421 |
> |
SET TERM |
422 |

SET STATS |
427 |
> |
SET NAMES <character set> |
428 |
> |
|
429 |
> |
10. IBVersion unit added to hold current IBX Version Number information. |
430 |
> |
|
431 |
> |
11. TIBExtract: Use character rather than byte length for VarChar procedure arguments., |
432 |
> |
and domain definitions. |
433 |
> |
|
434 |
> |
12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers |
435 |
> |
fully supported. |
436 |
> |
|
437 |

See also doc/IBX4LazarusGuide.pdf for important information on |
444 |
> |
upgrading to IBX2. |
445 |
> |
|
446 |
> |
1. Size property of TIBStringField is now the width in characters of the field |
447 |
> |
and not the byte length. This applies only to multi-byte character sets such |
448 |
> |
as UTF8. The original approach aligned with TStringField. However, the TStringField |
449 |
> |
code is not recognised as a bug and hence this change to align the behaviour. |
450 |
> |
The TStringField change is expected in fpc 3.2.0. |
451 |
> |
|
452 |
> |
2. A new property AutoFieldSize: boolean has been added to TIBStringField. When |
453 |
> |
true (default) then Size property value saved in the lfm is ignored. Size is |
454 |
> |
always set from the dynamic information read from the database. It is unclear |
455 |
> |
why anyone would want to override this and set Size to false. |
456 |
> |
|
457 |
> |
3. ibxscript: should now handle correctly a Case..End statement within a procedure |
458 |
> |
block. |
459 |
> |
|
460 |
> |
4. IBDatabase: new property - CreateIfNotExists. If true and database does not |
461 |
> |
exist when an attempt is made to connect to it (run time only) then an attempt |
462 |
> |
is made to create the database. |
463 |
> |
|
464 |
> |
5. IBDatabase: new event - OnCreateDatabase. This event is called after a database |
465 |
> |
has been successfully created as a result of a call to CreateDatabase or when |
466 |
> |
creating a database after it was found not to exist. |
467 |
> |
|
468 |
> |
6. DBControlGrid: a race condition could result in the wrong row image being |
469 |
> |
written to the cache. This has been avoided by a trip round the message |
470 |
> |
loop before rendering the row image. |
471 |
> |
|
472 |
> |
7. DBControlGrid: It is strongly recommended not to open the source DataSet for |
473 |
> |
a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is |
474 |
> |
known to risk corrupt rendering of row images when the control is first |
475 |
> |
displayed. If necessary use "Application.QueueAsyncCall" to delay opening |
476 |
> |
of the dataset (see DBControlGrid examples) until the Form's Window has been created. |
477 |
> |
|
478 |
> |
8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with |
479 |
> |
a TDateEdit control located on an editor panel. |
480 |
> |
|
481 |
> |
9. TIBExtract: brought up-to-date plus many bug fixes. |
482 |
> |
|
483 |
> |
10. DBControlGrid: Removed memory leak when updating rows. |
484 |
> |
|
485 |
> |
11. TIBCMLocalDBSupport: fixed invalid free on upgrade. |

489 |

1. IBCustomDataset: When calling SetCodePage, no longer request transliteration |
490 |
> |
when target codepage is CP_NONE. This is a workaround for |
491 |
> |
http://bugs.freepascal.org/view.php?id=30622. |
492 |
> |
|
493 |
> |
2. DBLog option removed from TIBStatisticalService - not supported by server |
494 |
> |
since Firebird 1.5. |
495 |
> |
|
496 |
> |
3. ibxscript: An error is no longer generated for "on commit preserve rows" or |
497 |
> |
similar. |
498 |
> |
|
499 |
> |
4. IBCodePage: updated mapping between codepages and character id. |
500 |
> |
|
501 |
> |
5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in |
502 |
> |
Firebird. Character sets with a char width of two are not UTF16. |
503 |
> |
|
504 |
> |
6. Strings received from the database are now always transliterated into UTF8 |
505 |
> |
regardless of the database character set or connection character set. This |
506 |
> |
is for compatibility with the LCL. |

1. IBBlob: Defer reading of blob until read method called. This avoids having to |
511 |
> |
read in an entire blob just to get the size of the blob. General performance |
512 |
> |
improvement when opening datasets containing blobs. |
513 |
> |
|
514 |
> |
2. Clearing a Blob now sets the corresponding field's modified flag. |
515 |
> |
|
516 |
> |
3. IBLookupCombo: When not performing auto-complete, original query sort order |
517 |
> |
is now used. |
518 |
> |
|
519 |
> |
4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically |
520 |
> |
determined. |
521 |
> |
|
522 |
> |
5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened. |
523 |
> |
|
524 |
> |
6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post |
525 |
> |
lazarus 1.6.0 |
526 |
> |
|
527 |
> |
7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages" |
528 |

1. No character set specified for connection: when a text blob is retrieved, the |
533 |
> |
character set is determined by looking up the native character set using then |
534 |
> |
Firebird API. Otherwise a text mode blob is assumed to have the same character |
535 |
> |
set as the connection. |
536 |
> |
|
537 |
> |
2. TIBGUIInterface: this is an internal interface. Minor type changes to allow |
538 |
> |
for Login Dialog returing a change to the database path. |
539 |
> |
|
540 |
> |
3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name |
541 |
> |
to be changed from that given in the TIBDatabase/TIBServer component and for the |
542 |
> |
entered value to be saved on a project specific basis (design time only). |
543 |
> |
|
544 |
> |
4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the |
545 |
> |
column fieldname. If they are the same then it is acts as a look up for the KeyValue |
546 |
> |
Otherwise, it sets the column text to the selected ListField Value. |
547 |
> |
|
548 |
> |
5. IBDynamicGrid: Only visible columns are now taken into account When recalculating |
549 |
> |
column width. |
550 |
> |
|
551 |
> |
6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given |
552 |
> |
and a case insensitive search is requested. |
553 |
> |
|
554 |
> |
7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls |
555 |
> |
or column ListSource. |
556 |
> |
|
557 |
> |
8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an |
558 |
> |
unprepare) when closing and the text has not changed. |
559 |
> |
|
560 |
> |
9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer. |
561 |
> |
Less likely to cause a cursor re-use error on Windows. |
562 |
> |
|
563 |
> |
10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin. |
564 |
> |
Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0. |
565 |
> |
|
566 |
> |
11. TIBTreeView: Guard against nil destination on record changed |
567 |
> |
|
568 |
> |
12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a |
569 |
> |
string type with the code page set to reflect the returned field encoding after |
570 |
> |
Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for |
571 |
> |
earlier versions. |
572 |
> |
|
573 |
> |
13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString |
574 |
> |
will now result in transliteration to the code page specified for the Firebird driver |
575 |
> |
if the assigned string has a different code page. FPC 3.0.0 onwards only. |
576 |
> |
|
577 |
> |
14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter |
578 |
> |
is ignored and the lc_ctype value, when the database is opened, is set to align with |
579 |
> |
the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure |
580 |
> |
platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC |
581 |
> |
3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when |
582 |
> |
the GETACP is used to determine the Windows code page. |
583 |
> |
|
584 |
> |
15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set |
585 |
> |
name used as the lc_ctype when the database was opened. Only valid while the |
586 |
> |
Database is connected. |
587 |
> |
|
588 |
> |
16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage |
589 |
> |
id that corresponds to the DefaultCharSetName. |

1. Unix: If Firebird Embedded Server shared object is loaded and a local database |
594 |
> |
path is given and database attach fails due to access permission issues on the |
595 |
> |
temp directory or security database, then the attach is retried with "localhost:" |
596 |
> |
prefixing the databasename. This should avoid problems when the database has to |
597 |
> |
be accessed by a local (e.g. classic) server and libfbembed is used. |
598 |
> |
|
599 |

2. Windows: revised search order for Firebird DLL: |
600 |
> |
i. The Firebird Embedded Server in the application Directory. |
601 |
> |
ii. If the FIREBIRD environment variable is set then the directory this |
602 |
> |
points to is searched for the FB Client DLL and then then underlying |
603 |
> |
"bin" directory. |
604 |
> |
iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances |
605 |
> |
is used to locate the Firebird installation directory and the underlying |
606 |
> |
"bin" directory is searched for the FB Client DLL. |
607 |
> |
iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x |
608 |
> |
are searched for the FB Client DLL. |
609 |
> |
v. The PATH Environment variable is used to search for the FB Client DLL. |
610 |
> |
vi. Finally the PATH Environment variable is used to search for IBASE.DLL. |
611 |
> |
|
612 |

3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine. |
613 |
> |
See doc/readme.scriptengine and example applications. |
614 |
> |
|
615 |
> |
4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to |
616 |
> |
simplify the use of the embedded firebird server on both Linux and Windows platforms. |
617 |
> |
See dpc/readme.localdatabase and example applications. |

5. IBDynamicGrid: Reordering on column header click should now also work for |
620 |
> |
dynamic columns. |
621 |
> |
|
622 |
> |
6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition |
623 |
> |
between incrementing/decrementing the lock count and signalling the event. |

1.3.2 was never formally released and only made available as beta copies. |
628 |

|
629 |
> |
1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo |
630 |
> |
|
631 |
> |
2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column |
632 |
> |
|
633 |
> |
3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early |
634 |
> |
|
635 |
> |
4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset |
636 |
> |
i.e. when it is a calculated field |
637 |
> |
|
638 |
> |
5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid. |
639 |
> |
This problem was due to a race condition between recalculating row heights and |
640 |
> |
determining which row was selected by the mouse click. The row height calculation |
641 |
> |
is now deferred by an extra trip round the message loop allowing the row to |
642 |

be always calculated on the current grid layout rather than risking it being |
643 |
> |
calculated on the grid layout after the expanded row has been shrunk. |

6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on |
646 |
> |
Windows. |
647 |
> |
|
648 |
> |
7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer; |
649 |
> |
These properties allow the (Firebird) character set name for the field and the max number of bytes per character |
650 |
> |
to be determined at runtime. See doc/readme.charactersets.html. |
651 |
> |
|
652 |
> |
8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from |
653 |
> |
TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html. |
654 |
> |
|
655 |
> |
9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from |
656 |
> |
TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of |
657 |
> |
1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html. |
658 |
> |
|
659 |
> |
Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated |
660 |
> |
from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero |
661 |
> |
implies no truncation. |
662 |
> |
|
663 |
> |
10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active. |
664 |
> |
|
665 |
> |
11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state |
666 |
> |
(avoids "Not in Edit Mode" error). |
667 |
> |
|
668 |
> |
12. IBDynamicGrid: Correctly resize grid when one column width plus indicator. |
669 |
> |
|
670 |
> |
13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling |
671 |
> |
DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control. |
672 |

IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100 |
682 |
> |
|
683 |
> |
1. OnCloseUp Event Handler added to TDBLookupProperties |
684 |
> |
|
685 |
> |
2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids |
686 |
> |
problem with row size when exception is called. |
687 |
> |
|
688 |
> |
3. IBLookupComboEditBox: Force pending autocomplete on combobox exit. |
689 |
> |
|
690 |
> |
4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if |
691 |
> |
in a TCustomComboBox and ignores return key if in a TCustomMemo |
692 |
> |
|
693 |
> |
5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text |
694 |
> |
keyed in i.e. when autocomplete not performed |
695 |
> |
|
696 |
> |
6. Cleanup of "Uses" clauses and add console mode support. IBX should now support |
697 |
> |
console mode applications with all LCL required functions (builtin dialogs and |
698 |
> |
cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is |
699 |
> |
not included in your project, IBX should compile and link with a console mode program. |
700 |
> |
See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a |
701 |
> |
console mode application or the IDE will automatically assume that your |
702 |
> |
application is GUI based. Instead, you should include the ibexpressconsolemode package. |
703 |
> |
|
704 |
> |
IMPORTANT NOTE: IBDialogs must be included in GUI applications in order |
705 |
> |
to use the built in dialogs and cursor management. IBDialogs is |
706 |
> |
included by default if "ibexpress" is in your project source's "uses" clause. |
707 |
> |
This should be the case for all projects created through the IDE. This is why |
708 |
> |
you do not want to add the ibexpress package to console mode applications. The |
709 |
> |
ibexpressconsolemode package has been created to allow console mode programs |
710 |
> |
to avoid adding LCL dependencies when using IBX, while still having the |
711 |
> |
unit search paths set up correctly. |
712 |
> |
|
713 |
> |
Existing users should check to ensure that the "ibexpress" unit is included in |
714 |
> |
each project's source file (*.lpr). |
715 |
> |
|
716 |
> |
You may find that in order for the IDE to recognise that ibexpressconsolemode |
717 |
> |
exists, you have to first open the package in the IDE and then close it. This |
718 |
> |
adds it to the most recently accessed packages list. To make it permanently |
719 |
> |
available, add the package name to lazarus' staticpackages.inc file. |
720 |
> |
|
721 |
> |
Thanks to Julio Jiménez for suggesting support of console mode. |
722 |
> |
|
723 |
> |
7. SQL Parser can now accept quoted strings that include new lines |
724 |
> |
|
725 |
> |
8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end |
726 |
> |
of text on start of edit. This is particularly useful when tabbing to a |
727 |
> |
column and then inserting text. |
728 |
> |
|
729 |
> |
9. New Examples provided for IB Services and ISQLMonitor. |
730 |
> |
|
731 |
> |
10. Fix error when writing to blob streams that recorded only the last buffer |
732 |
> |
write in the blob stream. In most cases, this did not cause a problem as the |
733 |
> |
IB Blob Stream is written in a single write. However, with the TDBImage, write |
734 |
> |
of a graphic type prefix was lost which caused a problem when the image could |
735 |
> |
not be automatically recognised. |
736 |
> |
|
737 |
> |
11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor |
738 |
> |
already open" errors due to random numbers used for the cursor name being identical. |
739 |
> |
|
740 |
> |
12. IBTable: corrected error that could result in an "Index out of bounds" error |
741 |
> |
when opening the table and the Primary Key is the last or only column in the |
742 |
> |
table. Thanks to Rick Hoover for the fix. |
743 |
> |
|
744 |
> |
13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead |
745 |
> |
of "UTF-8", and update list of available database character sets. Existing |
746 |
> |
users should check the current lc_ctype setting in their applications. |
747 |
> |

IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100 |
749 |
> |
|
750 |
> |
1. Firebird Services: avoid List Index error when opening a service with an |
751 |
> |
empty Params property. |
752 |
> |
|
753 |
> |
2. IBControls: Fix problem with new link mechanism introduced in 1.2.3. |
754 |
> |
Link now set up in Loaded method - avoids occasional failure to apply |
755 |
> |
SQL markup on initial open. |
756 |
> |
|
757 |
> |
3. "Employees" example performance improvements when scrolling. |
758 |
> |
|
759 |
> |
4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a |
760 |
> |
TFrame. Force recaching of selected frame to avoid GTK race (results in a |
761 |
> |
random image cached). |
762 |
> |
|
763 |
> |
5. DBControlGrid: Should now react to changes in panel height at run time. |
764 |
> |
|
765 |
> |
6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid |
766 |
> |
even when further rows exist. |
767 |
> |
|
768 |
> |
7. DBControlGrid: DefaultRowHeight is no longer a published property as it should |
769 |
> |
always be derived from panel height and setting this property can cause confusion. |
770 |
> |
Note for existing projects: to avoid a missing property error at run time, |
771 |
> |
each form using the DBControlGrid must be opened, updated and saved in the IDE |
772 |
> |
in order to remove the property value from the lfm. |
773 |

IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100 |
776 |
> |
|
777 |
> |
1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always |
778 |
> |
call Prepare before setting parameter values. |
779 |
> |
|
780 |
> |
2. Error message on ParamByName (all cases) not found now includes name of missing parameter. |
781 |
> |
|
782 |
> |
3. Code tidyup and more robust handling of dsql information result vector. |
783 |
> |
|
784 |
> |
4. Support for centralised handling of transaction status changes. TIBTransaction |
785 |
> |
has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost" |
786 |
> |
and "AfterExecQuery". The first three are called after the same event is called |
787 |
> |
for an IBCustomDataSet descendent using the Transaction. The fourth is called |
788 |
> |
after a call to TIBSQL.ExecQuery, again using this transaction. These new events |
789 |
> |
enable monitoring of transaction status changes for a given transaction to be |
790 |
> |
handled in a single place. For example, when a change to the dataset occurs |
791 |
> |
an indicator can be set that shows the user that in order to save changes, |
792 |
> |
the transaction should be committed. Rather than doing this per dataset, this |
793 |
> |
can now be done per transaction. |
794 |
> |
|
795 |
> |
5. TDataSet.CheckBrowseMode automatically posts changes to the current row when |
796 |
> |
the dataset is scrolled. However, any changes to the current row are, by default, |
797 |
> |
discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now |
798 |
> |
have a new property "DataSetCloseAction" that adds automatic posting of changes |
799 |
> |
on dataset close. If this property is set to dcDiscardChanges (default) then the |
800 |
> |
behaviour is unchanged from previous versions. if the value is set to dcSaveChanges |
801 |
> |
then IBX will attempt to post any unsaved changes before the dataset is closed |
802 |
> |
(and after the BeforeClose event handler is called). The exception is when the |
803 |
> |
dataset is being closed as a result of a transaction rollback. In this case, |
804 |
> |
no action is taken and any unsaved changes are discarded. This avoids both |
805 |
> |
unnecessary overhead and the risk that a validation error may occur in the Post |
806 |
> |
raising an exception and thereby preventing a rollback. |
807 |
> |
|
808 |
> |
6. String Field sizes and Display Widths should now be correct for multi-byte character sets. |
809 |
> |
In earlier versions, the Display Width was set to the maximum byte width rather than the character |
810 |
> |
width. Display Widths are now corrected by dividing by the max byte width per character. |
811 |
> |
For UTF8 character sets, the byte width is four and hence the Display Width will be |
812 |
> |
the byte width divided by 4. The byte width of each character set is determined |
813 |
> |
dynamically when the database connection is estabished from the RDB$CHARACTER_SETS |
814 |
> |
system table. (see also http://bugs.freepascal.org/view.php?id=27766). |
815 |
> |
|
816 |
> |
7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string. |
817 |
> |
|
818 |
> |
8. IBLookupComboEditBox: List should now always be restored to full list when the |
819 |
> |
control loses focus. Default Key press default interval reduced to 200ms. |
820 |
> |
|
821 |
> |
9. DBControlGrid: Ensure that selection is changed to newly appended row, even |
822 |
> |
when dataset rows are less than visible rows. |
823 |
> |
|
824 |
> |
10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource |
825 |
> |
does not exist or DataSet is empty. More responsive on dataset open. New event |
826 |
> |
OnRestorePosition. Column sort disabled if no header row. |
827 |
> |
|
828 |
> |
11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset |
829 |
> |
while dataset state is dsInsert. Avoids posting errors. |
830 |
> |
|
831 |
> |
12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to |
832 |
> |
avoid conflict with DisableControls/EnableControls with Master/Detail linked tables. |
833 |
> |
|
834 |
> |
13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes. |
835 |
> |
|
836 |
> |
14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced |
837 |
> |
to solve a specific problem. That is when the dataset cursor is moved (e.g. by |
838 |
> |
a grid mouse click and the current row is being edited or inserted. In this case, TDataset |
839 |
> |
always "posts" the current record regardless or whether or not it may be more appropriate |
840 |
> |
to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the |
841 |
> |
"MoveBy" function is implemented by TDataSet. The OnValidatePost event is called |
842 |
> |
as the first action of the "Post" method and allows the handler to convert the Post |
843 |
> |
into a Cancel if that is the appropriate action on moving to a different row. This is |
844 |
> |
achieved by returning with "CancelPost" argument set to true. Note that an exception could be |
845 |
> |
raised here, but it may still be more appropriate to validate a post and signal |
846 |
> |
a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml) |
847 |
> |
|
848 |
> |
15. On Unix derived systems, the Firebird library name can now be given as a colon |
849 |
> |
separated list. Each library name on the list is tried in turn, in left to right |
850 |
> |
order with the first found being used as the firebird library. By default, on Linux, |
851 |
> |
the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be |
852 |
> |
overidden by the FBLIB environment variable or the OnGetLibraryName function. |
853 |
> |
|
854 |
> |
Note: when using the libfbembed.so, if you prefix the database name with "localhost:" |
855 |
> |
then it will still attempt to access the database via the Firebird Server and will |
856 |
> |
require a username and password. If only the pathname is given, then the username |
857 |
> |
and password should be omitted and the unix file permissions are used to grant |
858 |
> |
access. |

|
862 |
> |
1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike |
863 |
> |
rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid |
864 |
> |
that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row |
865 |
> |
corresponds to a row of the linked DataSource. Any data aware control on the |
866 |
> |
replicated (e.g.) TPanel will then appear to have the appropriate value for the row. |
867 |
> |
|
868 |
> |
2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase. |
869 |
> |
When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change |
870 |
> |
takes place during database access. This may be useful when there are performance issues with |
871 |
> |
the change of cursor. Setting the property to false suppresses the change of cursor. |
872 |
> |
|
873 |
> |
3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery |
874 |
> |
and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to |
875 |
> |
Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of |
876 |
> |
making all changes permanent immediately rather than when the transaction is explicitly |
877 |
> |
committed. |
878 |
> |
|
879 |
> |
4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still |
880 |
> |
using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature. |

1. An internal select SQL Parser is now available for TIBCustomDataset descendents. |
889 |
> |
This is typically used during an "OnBeforeOpen" event handler to manipulate the |
890 |
> |
"Where" and "Having" clauses to implement user specified filters of arbitrary |
891 |
> |
complexity. |
892 |
> |
|
893 |
> |
2. A new Component Palette entry "Firebird Data Controls" is now available. This has |
894 |
> |
three new data aware controls dependent on IBX and which make use of the SQL Parser. |
895 |
> |
These are: |
896 |
> |
|
897 |
> |
- TIBLookupComboEditBox |
898 |
> |
- TIBDynamicGrid |
899 |
> |
- TIBTreeview |
900 |
> |
|
901 |
> |
TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete" |
902 |
> |
of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation |
903 |
> |
to revise the available list and restrict it to items that are prefixed by the |
904 |
> |
typed text (either case sensitive or case insensitive). Autoinsert allows a |
905 |
> |
newly typed entry to be added to the list dataset and included in the available |
906 |
> |
list items. |
907 |
> |
|
908 |
> |
TIBDynamicGrid is a TDBGrid descendent that provides for: |
909 |
> |
- automatic resizing of selected columns to fill the available row length |
910 |
> |
- automatic positioning and sizing of a "totals" control, typically at the |
911 |
> |
column footer, on a per column basis. |
912 |
> |
- DataSet resorting on header row click, sorting the dataset by the selected column. |
913 |
> |
A second click on the same header cell reversed the sort order. |
914 |
> |
- Support for a "Panel Editor". That is on clicking the indicator column, the row |
915 |
> |
is automatically expanded and a panel superimposed on it. The panel can have any |
916 |
> |
number of child controls, typically data aware controls with the same datasource |
917 |
> |
as the grid allowing for editing of additional fields and more complex editors. |
918 |
> |
- Reselection of the same row following resorting. |
919 |
> |
- A new cell editor that provides the same functionality as TIBLookupComboEditBox. |
920 |
> |
Its properties are specified on a per column basis and allows for one or more |
921 |
> |
columns to have their values selected from a list provided by a dataset. |
922 |
> |
Autocomplete and autoinsert are also available. The existing picklist editor |
923 |
> |
is unaffected by the extension. |
924 |
> |
|
925 |
> |
TIBTreeView is a data aware TCustomTreeView. |
926 |
> |
|
927 |
> |
3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a |
928 |
> |
zero scale will no longer return an error. An Int64 will be returned instead. |
929 |
> |
|
930 |
> |
4. TIBTransaction now has events for Before and After Transaction End and a new function |
931 |
> |
"GetEndAction" allowing the EndAction to be accessed by these event handlers. |
932 |
> |
|
933 |
> |
5. TIBQuery can now handle correctly queries which contain the same keyword parameter |
934 |
> |
repeated multiple times. |
935 |
> |
|
936 |
> |
6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error |
937 |
> |
check used to get in the way of using Stored Procedures, and "Update or Insert" |
938 |
> |
statements. |
939 |
> |
|
940 |
> |
7. Insert, Modify and Delete property Editors now support Query Generation from |
941 |
> |
Stored Procedures. |
942 |
> |
|
943 |
> |
8. Three new examples illustrate the use of the new IB Controls |

1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter |
949 |

setting performance. See "readme.field+param.names in the doc folder.(Thanks to |
950 |
> |
