1 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
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 deLayoutChanged 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
101 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
102
103 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
104 stubs. Pedantic fix really, as procedures output in dependency order anyway.
105
106 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
107 DDL (Firebird 3 and later only).
108
109 22. TIBLookupComboBox Autocomplete Fixes:
110 i. Only appended text is now selected after autocomplete.
111 ii. Uppercase keys no longer ignored for autocomplete.
112 iii. Retain Prefix case is now honoured correctly.
113 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
114 before autocomplete performed. i.e. behaviour now the same as when
115 no DataSource assigned.
116
117 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
118 between SQL statements.
119
120 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
121 ObjectNames are converted to upper case before matching against metadata object
122 names, unless the objectname is delimited by double quotes, in which case, the
123 double quotes are removed and the remaining string is used (unmodified) to match
124 against the metadata object name.
125
126 If true then the ObjectName is used as is without modification and matched
127 against the metadata object name. No attempt is made to remove double quotes.
128
129 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
130 with eoTrigger, these extract types can be used to select only Database Triggers,
131 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
132
133 26. TIBXScript: If an exception occurs during the processing of a statement, the
134 statement separate character is now reset to the default (';').
135
136 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
137
138 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
139 a commit or reconnect statement and instead activated only when next SQL statement
140 is executed.
141
142 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
143
144 30. TIBXScript: case insensitive regex now used when matching statements instead of
145 converting statement to upper case.
146
147 31. TIBExtract: metadata comments now supported. New published property
148 IncludeMetaDataComments (default true). If true then metadata comments included
149 in extracted DDL. New Extract Object member eoComments. This may be used with
150 ExtractObject method to list all metadata comments.
151
152 32. TIBExtract: ListObjectNames method added.
153
154 33. Updated Database component editor to support additional connection string
155 types.
156
157 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
158
159 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
160 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
161 RELEASE.
162
163 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
164
165 1. IBExtract: Identity columns - add additional check for null column for generator name.
166
167 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
168 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
169 information). However, this is also a very useful mechanism for returning updated computed by
170 column values. Values returned as a result of executing an Insert or Update statement
171 replace existing values in the current row for each corresponding column.
172
173 Previously, if a dataset's select query included read only (computed by) fields then
174 an automatic row refresh was performed after an insert or update query had been processed,
175 irrespective of the setting of the "ForcedUpdates" property. This has changed such
176 that an automatic refresh is no longer performed if an insert or update query contains
177 a returning clause that updates one or more fields on the current row. A full row
178 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
179 field values and the select query contains read only fields. Use of Insert/update
180 returning should be significantly more efficient than executing a refresh query.
181
182 This behaviour change is intended to be backwards compatible and there should be no need to change
183 existing programs, other than to improve performance by using the new capability.
184
185 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
186 they are called when the dataset row is being deleted, there is no value in
187 updating the current record from the query result. Instead, a new event handler
188 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
189 an OnDeleteReturning event handler is provided then it is called with the IResults returned
190 by the query. The event handler can then interrogate the query results and
191 perform whatever action is necessary. For example to confirm, to the user,
192 the deletion of a row with the returned values.
193
194 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
195 any Computed By or Identity Columns. The IBTables example has been updated to
196 illustrate the computation of the employee Full Name on update.
197
198 5. TIBTable: The GeneratorField property is now published.
199
200 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
201 When InsertSQL is generated, the Identity columns are not included in the list of values to
202 be inserted. A RETURNING clause is added to the insert statement to return the value of
203 each Identity column after the insert is executed.
204
205 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
206 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
207 Insert..Returning clause.
208
209 8. TIBGenerator: small performance improvement by not preparing query each time
210 a new value is generated.
211
212 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
213
214 10. Property editors will now sync table name to a System Table when "Include System
215 Tables" is selected and the query is for a System Table.
216
217 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
218 values are no longer converted to milliseconds from TDateTime and then back again
219 to TDateTime (the conversion to milliseconds is the default TDataset approach).
220
221 12. Property Editors handling of Stored Procedures.
222 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
223 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
224 query).
225 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
226
227 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
228 can be used to select a package. If non-empty, the stored procedure name is
229 expected to be a stored procedure defined in the specified package and the
230 generated SQL will be as required for a stored procedure located in a package.
231
232 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
233 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
234 which a stored procedure can be selected. With no package name selected, non-package
235 stored procedures are listed.
236
237 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
238 for password on reconnect.
239
240 16. TIBDatabase: use IAttachment for connection default character set id, code page
241 and character set name.
242
243 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
244 DB info lookups"
245
246 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
247
248 19. Add a property Editor for TIBUpdate.RefreshSQL.
249
250 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
251 parameters. This stops an exception being raised when the field cannot be
252 located in the record buffer.
253
254 21. Property Editors now automatically include System Tables when opened and when the query table
255 is a System Table.
256
257 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
258 This avoids errors due to a stale SQRB or SRB being used for the next query.
259
260 23. IBServices: Service attach parameters now include "expected_db". This is used to
261 add the SPB item isc_spb_expected_db. This names a database using
262 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
263 database. examples/services re-written to illustrate use of "expected_db".
264
265 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
266 This avoids truncated backups when the server returns a timeout (busy) response.
267
268 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
269
270 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
271 databasenames. These are respectively expanded to the local system's temp directory
272 (including trailing delimiter) or to a prescribed data directory (including
273 trailing delimiter). Under Unix systems the data directory is a hidden directory
274 in the user's home directory. The hidden directory name is either the string returned
275 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
276 Under Windows, the directory is the same as the Data Directory as decribed
277 above but instead prefixed by the User's application data path. These may be
278 used to improve application portability for Personal Databases.
279
280 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
281 this has not worked for a long time and is not useful either. FieldDefs should be
282 managed using the Fields Editor as with any other dataset. To access the fields
283 editor for a TIBTable component, double click on the component. The fields editor
284 is then displayed.
285
286 28. TIBDatabaseInfo: new properties/function
287 * DateDBCreated (returns date/time database created)
288 * TransactionCount (returns no. of active transactions)
289 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
290 * PagesFree (Firebird 3 or later)
291 * PagesUsed (Firebird 3 or later)
292 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
293 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
294
295 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
296
297 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
298
299 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
300 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
301
302 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
303 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
304 firing during backup and restore.
305
306 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
307 for verbose output using the new property "StatisticsRequested".
308 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
309
310 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
311
312 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
313 palette. This uses the online validation feature added in Firebird 2.5. The
314 services's properties enable inclusion/exclusion of tables and indexes using
315 regular expressions. See.
316 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
317
318 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
319 option on a database.
320
321 37. TIBCustomService: Assign method implemented to allow copying of service login
322 context between service API components. "Detach" method now only detaches
323 service when last reference to the service interface detaches. Tidy up of
324 code for SetActive and Attach methods including password hiding.
325
326 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
327 and used to determine the auth method and protocol used for the connection.
328
329 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
330 a Create Database Statement generated by IBX.
331
332 40. All IBServices now have an additional published property "PortNo". This may
333 be set to a non-standard port number when necessary. If zero then the default
334 port number is used.
335
336 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
337 and not just the mouse.
338
339 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
340
341 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
342 image index and selected image index for each node to be set from a database field.
343
344 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
345 then database schema includes grants to all users. If not present then the
346 only user grants included are those to User PUBLIC.
347
348 45. TIBTreeView: performance improvement. When expanding include both expanded node
349 and child nodes in dataset.
350
351
352 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
353
354 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
355 changes.
356
357 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
358 Bug could result in truncated multi-byte character set values.
359
360 3. Changes consequential on moving fbintf character set utility functions from
361 IFirebirdAPI to IAttachment.
362
363 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
364
365 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
366 results in autocomplete ignoring prefix text.
367
368 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
369 entering a new name into the text box.
370
371 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
372 Firebird rather than recomputing it.
373
374 8. Property Editor positioning tidy up: All IBX Property editors should now be
375 screen centre. Previously some were "poDesigned" which may be inappropriate
376 for multi monitor desktops.
377
378 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
379
380 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
381 a transaction and always reset the object.
382
383 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
384
385 13. TIBXScript: Allow for override of database filename in Create Database statements.
386
387 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
388 to a gbak format archive.
389
390 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
391
392 16. IBLocaldb: Drop database if error creating an empty database.
393
394 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
395 unless selected node not in current dataset.
396
397 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
398 to TIBCustomService, and IBlocalDB code tidy up.
399
400 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
401 behaviour due to uninitialised variable.
402
403 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
404 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
405
406 21. IBSQL: When Database changed ensure that all resources are freed.
407
408 22. IBCustomDataset: When database changed ensure that queries an unprepared.
409
410 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
411 * Line Wrap on SQL Token boundaries (on user command)
412 * auto-complete table names in drop down list of table names
413 * Double click on tablename or field name adds to SQL text
414
415 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
416
417 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
418 TVariantArray. Seems to avoid memory corruption in Windows (probably a
419 workaround for a problem in fpc 3.0.4 win64).
420
421 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
422
423 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
424
425 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
426
427 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
428 include remote system name.
429
430 2. TIBExtract: No longer include comment header and COMMIT statement for empty
431 tables when data included in output.
432
433 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
434 and timing information to be written to stdout. This may be used to locate
435 performance bottlenecks.
436
437 4. SQLParser: only call "OnChanging" event handler when value is different.
438
439 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
440
441 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
442 that BindFields is called when the query is next activated. Avoids FieldName
443 not found error.
444
445 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
446 purpose and allows the programmer to define any action they want for Update, Insert
447 or Delete. This may be complex SQL (similar to a Trigger), application specific
448 filtering of updates, or use of statements such as Grant or Revoke instead of
449 normal DML. See User Manual for more information.
450
451 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
452
453 1. TIBEvents: Fix uninitialised variable that could result in lost events.
454
455 2. TIBExtract: Added support for FB3 "USAGE" privilege.
456
457 3. TIBExtract: data formatted as Charset set "octets" is now output using
458 hexadecimal notation.
459
460 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
461 using a simple XML format.
462
463 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
464 grants to these objects.
465
466 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
467 dependency problems restoring complex databases.
468
469 7. TIBXScript: This component has been restructured to allow for the processing of
470 embedded XML in INSERT statements and to support interactive sources in addition
471 to non-interactive data sources such as files.
472
473 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
474
475 9. TIBXScript: ISQL compatiable Set statements are now supported:
476 SET SQL DIALECT
477 SET TERM
478 SET AUTODDL
479 SET BAIL
480 SET ECHO
481 SET COUNT
482 SET STATS
483 SET NAMES <character set>
484
485 10. IBVersion unit added to hold current IBX Version Number information.
486
487 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
488 and domain definitions.
489
490 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
491 fully supported.
492
493 13. TIBExtract: when a database dump includes data, the generator values are now also set.
494
495 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
496
497 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
498
499 See also doc/IBX4LazarusGuide.pdf for important information on
500 upgrading to IBX2.
501
502 1. Size property of TIBStringField is now the width in characters of the field
503 and not the byte length. This applies only to multi-byte character sets such
504 as UTF8. The original approach aligned with TStringField. However, the TStringField
505 code is not recognised as a bug and hence this change to align the behaviour.
506 The TStringField change is expected in fpc 3.2.0.
507
508 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
509 true (default) then Size property value saved in the lfm is ignored. Size is
510 always set from the dynamic information read from the database. It is unclear
511 why anyone would want to override this and set Size to false.
512
513 3. ibxscript: should now handle correctly a Case..End statement within a procedure
514 block.
515
516 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
517 exist when an attempt is made to connect to it (run time only) then an attempt
518 is made to create the database.
519
520 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
521 has been successfully created as a result of a call to CreateDatabase or when
522 creating a database after it was found not to exist.
523
524 6. DBControlGrid: a race condition could result in the wrong row image being
525 written to the cache. This has been avoided by a trip round the message
526 loop before rendering the row image.
527
528 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
529 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
530 known to risk corrupt rendering of row images when the control is first
531 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
532 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
533
534 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
535 a TDateEdit control located on an editor panel.
536
537 9. TIBExtract: brought up-to-date plus many bug fixes.
538
539 10. DBControlGrid: Removed memory leak when updating rows.
540
541 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
542
543 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
544
545 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
546 when target codepage is CP_NONE. This is a workaround for
547 http://bugs.freepascal.org/view.php?id=30622.
548
549 2. DBLog option removed from TIBStatisticalService - not supported by server
550 since Firebird 1.5.
551
552 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
553 similar.
554
555 4. IBCodePage: updated mapping between codepages and character id.
556
557 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
558 Firebird. Character sets with a char width of two are not UTF16.
559
560 6. Strings received from the database are now always transliterated into UTF8
561 regardless of the database character set or connection character set. This
562 is for compatibility with the LCL.
563
564 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
565
566 1. IBBlob: Defer reading of blob until read method called. This avoids having to
567 read in an entire blob just to get the size of the blob. General performance
568 improvement when opening datasets containing blobs.
569
570 2. Clearing a Blob now sets the corresponding field's modified flag.
571
572 3. IBLookupCombo: When not performing auto-complete, original query sort order
573 is now used.
574
575 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
576 determined.
577
578 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
579
580 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
581 lazarus 1.6.0
582
583 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
584 compilation error.
585
586 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
587
588 1. No character set specified for connection: when a text blob is retrieved, the
589 character set is determined by looking up the native character set using then
590 Firebird API. Otherwise a text mode blob is assumed to have the same character
591 set as the connection.
592
593 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
594 for Login Dialog returing a change to the database path.
595
596 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
597 to be changed from that given in the TIBDatabase/TIBServer component and for the
598 entered value to be saved on a project specific basis (design time only).
599
600 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
601 column fieldname. If they are the same then it is acts as a look up for the KeyValue
602 Otherwise, it sets the column text to the selected ListField Value.
603
604 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
605 column width.
606
607 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
608 and a case insensitive search is requested.
609
610 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
611 or column ListSource.
612
613 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
614 unprepare) when closing and the text has not changed.
615
616 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
617 Less likely to cause a cursor re-use error on Windows.
618
619 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
620 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
621
622 11. TIBTreeView: Guard against nil destination on record changed
623
624 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
625 string type with the code page set to reflect the returned field encoding after
626 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
627 earlier versions.
628
629 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
630 will now result in transliteration to the code page specified for the Firebird driver
631 if the assigned string has a different code page. FPC 3.0.0 onwards only.
632
633 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
634 is ignored and the lc_ctype value, when the database is opened, is set to align with
635 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
636 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
637 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
638 the GETACP is used to determine the Windows code page.
639
640 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
641 name used as the lc_ctype when the database was opened. Only valid while the
642 Database is connected.
643
644 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
645 id that corresponds to the DefaultCharSetName.
646
647 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
648
649 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
650 path is given and database attach fails due to access permission issues on the
651 temp directory or security database, then the attach is retried with "localhost:"
652 prefixing the databasename. This should avoid problems when the database has to
653 be accessed by a local (e.g. classic) server and libfbembed is used.
654
655 2. Windows: revised search order for Firebird DLL:
656 i. The Firebird Embedded Server in the application Directory.
657 ii. If the FIREBIRD environment variable is set then the directory this
658 points to is searched for the FB Client DLL and then then underlying
659 "bin" directory.
660 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
661 is used to locate the Firebird installation directory and the underlying
662 "bin" directory is searched for the FB Client DLL.
663 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
664 are searched for the FB Client DLL.
665 v. The PATH Environment variable is used to search for the FB Client DLL.
666 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
667
668 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
669 See doc/readme.scriptengine and example applications.
670
671 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
672 simplify the use of the embedded firebird server on both Linux and Windows platforms.
673 See dpc/readme.localdatabase and example applications.
674
675 5. IBDynamicGrid: Reordering on column header click should now also work for
676 dynamic columns.
677
678 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
679 between incrementing/decrementing the lock count and signalling the event.
680
681 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
682
683 1.3.2 was never formally released and only made available as beta copies.
684
685 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
686
687 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
688
689 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
690
691 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
692 i.e. when it is a calculated field
693
694 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
695 This problem was due to a race condition between recalculating row heights and
696 determining which row was selected by the mouse click. The row height calculation
697 is now deferred by an extra trip round the message loop allowing the row to
698 be always calculated on the current grid layout rather than risking it being
699 calculated on the grid layout after the expanded row has been shrunk.
700
701 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
702 Windows.
703
704 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
705 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
706 to be determined at runtime. See doc/readme.charactersets.html.
707
708 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
709 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
710
711 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
712 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
713 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
714
715 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
716 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
717 implies no truncation.
718
719 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
720
721 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
722 (avoids "Not in Edit Mode" error).
723
724 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
725
726 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
727 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
728
729 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
730
731 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
732
733 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
734
735 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
736
737 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
738
739 1. OnCloseUp Event Handler added to TDBLookupProperties
740
741 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
742 problem with row size when exception is called.
743
744 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
745
746 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
747 in a TCustomComboBox and ignores return key if in a TCustomMemo
748
749 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
750 keyed in i.e. when autocomplete not performed
751
752 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
753 console mode applications with all LCL required functions (builtin dialogs and
754 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
755 not included in your project, IBX should compile and link with a console mode program.
756 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
757 console mode application or the IDE will automatically assume that your
758 application is GUI based. Instead, you should include the ibexpressconsolemode package.
759
760 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
761 to use the built in dialogs and cursor management. IBDialogs is
762 included by default if "ibexpress" is in your project source's "uses" clause.
763 This should be the case for all projects created through the IDE. This is why
764 you do not want to add the ibexpress package to console mode applications. The
765 ibexpressconsolemode package has been created to allow console mode programs
766 to avoid adding LCL dependencies when using IBX, while still having the
767 unit search paths set up correctly.
768
769 Existing users should check to ensure that the "ibexpress" unit is included in
770 each project's source file (*.lpr).
771
772 You may find that in order for the IDE to recognise that ibexpressconsolemode
773 exists, you have to first open the package in the IDE and then close it. This
774 adds it to the most recently accessed packages list. To make it permanently
775 available, add the package name to lazarus' staticpackages.inc file.
776
777 Thanks to Julio Jiménez for suggesting support of console mode.
778
779 7. SQL Parser can now accept quoted strings that include new lines
780
781 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
782 of text on start of edit. This is particularly useful when tabbing to a
783 column and then inserting text.
784
785 9. New Examples provided for IB Services and ISQLMonitor.
786
787 10. Fix error when writing to blob streams that recorded only the last buffer
788 write in the blob stream. In most cases, this did not cause a problem as the
789 IB Blob Stream is written in a single write. However, with the TDBImage, write
790 of a graphic type prefix was lost which caused a problem when the image could
791 not be automatically recognised.
792
793 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
794 already open" errors due to random numbers used for the cursor name being identical.
795
796 12. IBTable: corrected error that could result in an "Index out of bounds" error
797 when opening the table and the Primary Key is the last or only column in the
798 table. Thanks to Rick Hoover for the fix.
799
800 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
801 of "UTF-8", and update list of available database character sets. Existing
802 users should check the current lc_ctype setting in their applications.
803
804 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
805
806 1. Firebird Services: avoid List Index error when opening a service with an
807 empty Params property.
808
809 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
810 Link now set up in Loaded method - avoids occasional failure to apply
811 SQL markup on initial open.
812
813 3. "Employees" example performance improvements when scrolling.
814
815 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
816 TFrame. Force recaching of selected frame to avoid GTK race (results in a
817 random image cached).
818
819 5. DBControlGrid: Should now react to changes in panel height at run time.
820
821 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
822 even when further rows exist.
823
824 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
825 always be derived from panel height and setting this property can cause confusion.
826 Note for existing projects: to avoid a missing property error at run time,
827 each form using the DBControlGrid must be opened, updated and saved in the IDE
828 in order to remove the property value from the lfm.
829
830
831 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
832
833 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
834 call Prepare before setting parameter values.
835
836 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
837
838 3. Code tidyup and more robust handling of dsql information result vector.
839
840 4. Support for centralised handling of transaction status changes. TIBTransaction
841 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
842 and "AfterExecQuery". The first three are called after the same event is called
843 for an IBCustomDataSet descendent using the Transaction. The fourth is called
844 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
845 enable monitoring of transaction status changes for a given transaction to be
846 handled in a single place. For example, when a change to the dataset occurs
847 an indicator can be set that shows the user that in order to save changes,
848 the transaction should be committed. Rather than doing this per dataset, this
849 can now be done per transaction.
850
851 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
852 the dataset is scrolled. However, any changes to the current row are, by default,
853 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
854 have a new property "DataSetCloseAction" that adds automatic posting of changes
855 on dataset close. If this property is set to dcDiscardChanges (default) then the
856 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
857 then IBX will attempt to post any unsaved changes before the dataset is closed
858 (and after the BeforeClose event handler is called). The exception is when the
859 dataset is being closed as a result of a transaction rollback. In this case,
860 no action is taken and any unsaved changes are discarded. This avoids both
861 unnecessary overhead and the risk that a validation error may occur in the Post
862 raising an exception and thereby preventing a rollback.
863
864 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
865 In earlier versions, the Display Width was set to the maximum byte width rather than the character
866 width. Display Widths are now corrected by dividing by the max byte width per character.
867 For UTF8 character sets, the byte width is four and hence the Display Width will be
868 the byte width divided by 4. The byte width of each character set is determined
869 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
870 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
871
872 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
873
874 8. IBLookupComboEditBox: List should now always be restored to full list when the
875 control loses focus. Default Key press default interval reduced to 200ms.
876
877 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
878 when dataset rows are less than visible rows.
879
880 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
881 does not exist or DataSet is empty. More responsive on dataset open. New event
882 OnRestorePosition. Column sort disabled if no header row.
883
884 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
885 while dataset state is dsInsert. Avoids posting errors.
886
887 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
888 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
889
890 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
891
892 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
893 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
894 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
895 always "posts" the current record regardless or whether or not it may be more appropriate
896 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
897 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
898 as the first action of the "Post" method and allows the handler to convert the Post
899 into a Cancel if that is the appropriate action on moving to a different row. This is
900 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
901 raised here, but it may still be more appropriate to validate a post and signal
902 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
903
904 15. On Unix derived systems, the Firebird library name can now be given as a colon
905 separated list. Each library name on the list is tried in turn, in left to right
906 order with the first found being used as the firebird library. By default, on Linux,
907 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
908 overidden by the FBLIB environment variable or the OnGetLibraryName function.
909
910 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
911 then it will still attempt to access the database via the Firebird Server and will
912 require a username and password. If only the pathname is given, then the username
913 and password should be omitted and the unix file permissions are used to grant
914 access.
915
916 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
917
918 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
919 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
920 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
921 corresponds to a row of the linked DataSource. Any data aware control on the
922 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
923
924 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
925 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
926 takes place during database access. This may be useful when there are performance issues with
927 the change of cursor. Setting the property to false suppresses the change of cursor.
928
929 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
930 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
931 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
932 making all changes permanent immediately rather than when the transaction is explicitly
933 committed.
934
935 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
936 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

942 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
943
944 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
945 This is typically used during an "OnBeforeOpen" event handler to manipulate the
946 "Where" and "Having" clauses to implement user specified filters of arbitrary
947 complexity.
948
949 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
950 three new data aware controls dependent on IBX and which make use of the SQL Parser.
951 These are:
952
953 - TIBLookupComboEditBox
954 - TIBDynamicGrid
955 - TIBTreeview
956
957 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
958 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
959 to revise the available list and restrict it to items that are prefixed by the
960 typed text (either case sensitive or case insensitive). Autoinsert allows a
961 newly typed entry to be added to the list dataset and included in the available
962 list items.
963
964 TIBDynamicGrid is a TDBGrid descendent that provides for:
965 - automatic resizing of selected columns to fill the available row length
966 - automatic positioning and sizing of a "totals" control, typically at the
967 column footer, on a per column basis.
968 - DataSet resorting on header row click, sorting the dataset by the selected column.
969 A second click on the same header cell reversed the sort order.
970 - Support for a "Panel Editor". That is on clicking the indicator column, the row
971 is automatically expanded and a panel superimposed on it. The panel can have any
972 number of child controls, typically data aware controls with the same datasource
973 as the grid allowing for editing of additional fields and more complex editors.
974 - Reselection of the same row following resorting.
975 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
976 Its properties are specified on a per column basis and allows for one or more
977 columns to have their values selected from a list provided by a dataset.
978 Autocomplete and autoinsert are also available. The existing picklist editor
979 is unaffected by the extension.
980
981 TIBTreeView is a data aware TCustomTreeView.
982
983 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
984 zero scale will no longer return an error. An Int64 will be returned instead.
985
986 4. TIBTransaction now has events for Before and After Transaction End and a new function
987 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
988
989 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
990 repeated multiple times.
991
992 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
993 check used to get in the way of using Stored Procedures, and "Update or Insert"
994 statements.
995
996 7. Insert, Modify and Delete property Editors now support Query Generation from
997 Stored Procedures.
998
999 8. Three new examples illustrate the use of the new IB Controls

1002 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1003
1004 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1005 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1006 Gabor Boros for reporting this problem and for testing the improvements).
1007
1008 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1009 See readme.field+param.names in the doc folder.
1010
1011 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1012 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1013
1014 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1015
1016 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1017 actions.
1018
1019 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1020 thanks to Yuriy Kopnin for pointing this out).
1021
1022 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1023
1024 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1025 for both fields and parameter setting.
1026
1027 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1028 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1029
1030 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1031 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1032
1033 11. TIBTable now has a property editor for "MasterFields"
1034
1035 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1036 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1037
1038 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1039 of settings is unrecognised. Selecting this radio button has no effect on the settings.

1042 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1043
1044 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1045
1046 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1047
1048 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1049 it is null. This allows for alternative user defined setting of the generator
1050
1051 Many thanks to Julio Jiménez for this fix
1052
1053 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1054 and suggests that the user may have forgotten to install it.
1055
1056 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1057
1058 1. Conditional compilation used to limit registration of TIntegerField to
1059 Lazarus versions less than 1.1
1060
1061 2. When a database connection is created, character set is now by default set
1062 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1063 1250 to 1254.
1064
1065
1066 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1067
1068 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1069
1070
1071 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1072
1073 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1074 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1075
1076 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1077 package is changed to do this (which it should do).
1078
1079 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1080
1081 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1082
1083 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1084
1085 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1086
1087 4. Property editors should now correctly resize.
1088
1089 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1090 (restored original functionality)
1091
1092 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1093 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
