1 IBX Change Log version (2.0.3) tba, 24 Feb 2017 12:17:53 +0000
2
3 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
4 changes.
5
6 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
7 Bug could result in truncated multi-byte character set values.
8
9 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
10
11 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
12 include remote system name.
13
14 2. TIBExtract: No longer include comment header and COMMIT statement for empty
15 tables when data included in output.
16
17 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
18 and timing information to be written to stdout. This may be used to locate
19 performance bottlenecks.
20
21 4. SQLParser: only call "OnChanging" event handler when value is different.
22
23 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
24
25 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
26 that BindFields is called when the query is next activated. Avoids FieldName
27 not found error.
28
29 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
30
31 1. TIBEvents: Fix uninitialised variable that could result in lost events.
32
33 2. TIBExtract: Added support for FB3 "USAGE" privilege.
34
35 3. TIBExtract: data formatted as Charset set "octets" is now output using
36 hexadecimal notation.
37
38 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
39 using a simple XML format.
40
41 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
42 grants to these objects.
43
44 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
45 dependency problems restoring complex databases.
46
47 7. TIBXScript: This component has been restructured to allow for the processing of
48 embedded XML in INSERT statements and to support interactive sources in addition
49 to non-interactive data sources such as files.
50
51 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
52
53 9. TIBXScript: ISQL compatiable Set statements are now supported:
54 SET SQL DIALECT
55 SET TERM
56 SET AUTODDL
57 SET BAIL
58 SET ECHO
59 SET COUNT
60 SET STATS
61 SET NAMES <character set>
62
63 10. IBVersion unit added to hold current IBX Version Number information.
64
65 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
66 and domain definitions.
67
68 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
69 fully supported.
70
71 13. TIBExtract: when a database dump includes data, the generator values are now also set.
72
73 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
74
75 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
76
77 See also doc/IBX4LazarusGuide.pdf for important information on
78 upgrading to IBX2.
79
80 1. Size property of TIBStringField is now the width in characters of the field
81 and not the byte length. This applies only to multi-byte character sets such
82 as UTF8. The original approach aligned with TStringField. However, the TStringField
83 code is not recognised as a bug and hence this change to align the behaviour.
84 The TStringField change is expected in fpc 3.2.0.
85
86 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
87 true (default) then Size property value saved in the lfm is ignored. Size is
88 always set from the dynamic information read from the database. It is unclear
89 why anyone would want to override this and set Size to false.
90
91 3. ibxscript: should now handle correctly a Case..End statement within a procedure
92 block.
93
94 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
95 exist when an attempt is made to connect to it (run time only) then an attempt
96 is made to create the database.
97
98 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
99 has been successfully created as a result of a call to CreateDatabase or when
100 creating a database after it was found not to exist.
101
102 6. DBControlGrid: a race condition could result in the wrong row image being
103 written to the cache. This has been avoided by a trip round the message
104 loop before rendering the row image.
105
106 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
107 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
108 known to risk corrupt rendering of row images when the control is first
109 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
110 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
111
112 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
113 a TDateEdit control located on an editor panel.
114
115 9. TIBExtract: brought up-to-date plus many bug fixes.
116
117 10. DBControlGrid: Removed memory leak when updating rows.
118
119 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
120
121 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
122
123 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
124 when target codepage is CP_NONE. This is a workaround for
125 http://bugs.freepascal.org/view.php?id=30622.
126
127 2. DBLog option removed from TIBStatisticalService - not supported by server
128 since Firebird 1.5.
129
130 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
131 similar.
132
133 4. IBCodePage: updated mapping between codepages and character id.
134
135 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
136 Firebird. Character sets with a char width of two are not UTF16.
137
138 6. Strings received from the database are now always transliterated into UTF8
139 regardless of the database character set or connection character set. This
140 is for compatibility with the LCL.
141
142 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
143
144 1. IBBlob: Defer reading of blob until read method called. This avoids having to
145 read in an entire blob just to get the size of the blob. General performance
146 improvement when opening datasets containing blobs.
147
148 2. Clearing a Blob now sets the corresponding field's modified flag.
149
150 3. IBLookupCombo: When not performing auto-complete, original query sort order
151 is now used.
152
153 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
154 determined.
155
156 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
157
158 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
159 lazarus 1.6.0
160
161 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
162 compilation error.
163
164 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
165
166 1. No character set specified for connection: when a text blob is retrieved, the
167 character set is determined by looking up the native character set using then
168 Firebird API. Otherwise a text mode blob is assumed to have the same character
169 set as the connection.
170
171 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
172 for Login Dialog returing a change to the database path.
173
174 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
175 to be changed from that given in the TIBDatabase/TIBServer component and for the
176 entered value to be saved on a project specific basis (design time only).
177
178 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
179 column fieldname. If they are the same then it is acts as a look up for the KeyValue
180 Otherwise, it sets the column text to the selected ListField Value.
181
182 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
183 column width.
184
185 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
186 and a case insensitive search is requested.
187
188 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
189 or column ListSource.
190
191 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
192 unprepare) when closing and the text has not changed.
193
194 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
195 Less likely to cause a cursor re-use error on Windows.
196
197 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
198 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
199
200 11. TIBTreeView: Guard against nil destination on record changed
201
202 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
203 string type with the code page set to reflect the returned field encoding after
204 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
205 earlier versions.
206
207 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
208 will now result in transliteration to the code page specified for the Firebird driver
209 if the assigned string has a different code page. FPC 3.0.0 onwards only.
210
211 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
212 is ignored and the lc_ctype value, when the database is opened, is set to align with
213 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
214 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
215 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
216 the GETACP is used to determine the Windows code page.
217
218 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
219 name used as the lc_ctype when the database was opened. Only valid while the
220 Database is connected.
221
222 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
223 id that corresponds to the DefaultCharSetName.
224
225 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
226
227 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
228 path is given and database attach fails due to access permission issues on the
229 temp directory or security database, then the attach is retried with "localhost:"
230 prefixing the databasename. This should avoid problems when the database has to
231 be accessed by a local (e.g. classic) server and libfbembed is used.
232
233 2. Windows: revised search order for Firebird DLL:
234 i. The Firebird Embedded Server in the application Directory.
235 ii. If the FIREBIRD environment variable is set then the directory this
236 points to is searched for the FB Client DLL and then then underlying
237 "bin" directory.
238 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
239 is used to locate the Firebird installation directory and the underlying
240 "bin" directory is searched for the FB Client DLL.
241 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
242 are searched for the FB Client DLL.
243 v. The PATH Environment variable is used to search for the FB Client DLL.
244 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
245
246 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
247 See doc/readme.scriptengine and example applications.
248
249 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
250 simplify the use of the embedded firebird server on both Linux and Windows platforms.
251 See dpc/readme.localdatabase and example applications.
252
253 5. IBDynamicGrid: Reordering on column header click should now also work for
254 dynamic columns.
255
256 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
257 between incrementing/decrementing the lock count and signalling the event.
258
259 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
260
261 1.3.2 was never formally released and only made available as beta copies.
262
263 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
264
265 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
266
267 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
268
269 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
270 i.e. when it is a calculated field
271
272 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
273 This problem was due to a race condition between recalculating row heights and
274 determining which row was selected by the mouse click. The row height calculation
275 is now deferred by an extra trip round the message loop allowing the row to
276 be always calculated on the current grid layout rather than risking it being
277 calculated on the grid layout after the expanded row has been shrunk.
278
279 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
280 Windows.
281
282 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
283 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
284 to be determined at runtime. See doc/readme.charactersets.html.
285
286 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
287 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
288
289 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
290 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
291 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
292
293 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
294 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
295 implies no truncation.
296
297 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
298
299 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
300 (avoids "Not in Edit Mode" error).
301
302 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
303
304 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
305 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
306
307 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
308
309 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
310
311 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
312
313 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
314
315 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
316
317 1. OnCloseUp Event Handler added to TDBLookupProperties
318
319 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
320 problem with row size when exception is called.
321
322 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
323
324 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
325 in a TCustomComboBox and ignores return key if in a TCustomMemo
326
327 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
328 keyed in i.e. when autocomplete not performed
329
330 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
331 console mode applications with all LCL required functions (builtin dialogs and
332 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
333 not included in your project, IBX should compile and link with a console mode program.
334 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
335 console mode application or the IDE will automatically assume that your
336 application is GUI based. Instead, you should include the ibexpressconsolemode package.
337
338 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
339 to use the built in dialogs and cursor management. IBDialogs is
340 included by default if "ibexpress" is in your project source's "uses" clause.
341 This should be the case for all projects created through the IDE. This is why
342 you do not want to add the ibexpress package to console mode applications. The
343 ibexpressconsolemode package has been created to allow console mode programs
344 to avoid adding LCL dependencies when using IBX, while still having the
345 unit search paths set up correctly.
346
347 Existing users should check to ensure that the "ibexpress" unit is included in
348 each project's source file (*.lpr).
349
350 You may find that in order for the IDE to recognise that ibexpressconsolemode
351 exists, you have to first open the package in the IDE and then close it. This
352 adds it to the most recently accessed packages list. To make it permanently
353 available, add the package name to lazarus' staticpackages.inc file.
354
355 Thanks to Julio Jiménez for suggesting support of console mode.
356
357 7. SQL Parser can now accept quoted strings that include new lines
358
359 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
360 of text on start of edit. This is particularly useful when tabbing to a
361 column and then inserting text.
362
363 9. New Examples provided for IB Services and ISQLMonitor.
364
365 10. Fix error when writing to blob streams that recorded only the last buffer
366 write in the blob stream. In most cases, this did not cause a problem as the
367 IB Blob Stream is written in a single write. However, with the TDBImage, write
368 of a graphic type prefix was lost which caused a problem when the image could
369 not be automatically recognised.
370
371 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
372 already open" errors due to random numbers used for the cursor name being identical.
373
374 12. IBTable: corrected error that could result in an "Index out of bounds" error
375 when opening the table and the Primary Key is the last or only column in the
376 table. Thanks to Rick Hoover for the fix.
377
378 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
379 of "UTF-8", and update list of available database character sets. Existing
380 users should check the current lc_ctype setting in their applications.
381
382 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
383
384 1. Firebird Services: avoid List Index error when opening a service with an
385 empty Params property.
386
387 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
388 Link now set up in Loaded method - avoids occasional failure to apply
389 SQL markup on initial open.
390
391 3. "Employees" example performance improvements when scrolling.
392
393 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
394 TFrame. Force recaching of selected frame to avoid GTK race (results in a
395 random image cached).
396
397 5. DBControlGrid: Should now react to changes in panel height at run time.
398
399 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
400 even when further rows exist.
401
402 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
403 always be derived from panel height and setting this property can cause confusion.
404 Note for existing projects: to avoid a missing property error at run time,
405 each form using the DBControlGrid must be opened, updated and saved in the IDE
406 in order to remove the property value from the lfm.
407
408
409 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
410
411 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
412 call Prepare before setting parameter values.
413
414 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
415
416 3. Code tidyup and more robust handling of dsql information result vector.
417
418 4. Support for centralised handling of transaction status changes. TIBTransaction
419 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
420 and "AfterExecQuery". The first three are called after the same event is called
421 for an IBCustomDataSet descendent using the Transaction. The fourth is called
422 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
423 enable monitoring of transaction status changes for a given transaction to be
424 handled in a single place. For example, when a change to the dataset occurs
425 an indicator can be set that shows the user that in order to save changes,
426 the transaction should be committed. Rather than doing this per dataset, this
427 can now be done per transaction.
428
429 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
430 the dataset is scrolled. However, any changes to the current row are, by default,
431 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
432 have a new property "DataSetCloseAction" that adds automatic posting of changes
433 on dataset close. If this property is set to dcDiscardChanges (default) then the
434 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
435 then IBX will attempt to post any unsaved changes before the dataset is closed
436 (and after the BeforeClose event handler is called). The exception is when the
437 dataset is being closed as a result of a transaction rollback. In this case,
438 no action is taken and any unsaved changes are discarded. This avoids both
439 unnecessary overhead and the risk that a validation error may occur in the Post
440 raising an exception and thereby preventing a rollback.
441
442 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
443 In earlier versions, the Display Width was set to the maximum byte width rather than the character
444 width. Display Widths are now corrected by dividing by the max byte width per character.
445 For UTF8 character sets, the byte width is four and hence the Display Width will be
446 the byte width divided by 4. The byte width of each character set is determined
447 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
448 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
449
450 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
451
452 8. IBLookupComboEditBox: List should now always be restored to full list when the
453 control loses focus. Default Key press default interval reduced to 200ms.
454
455 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
456 when dataset rows are less than visible rows.
457
458 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
459 does not exist or DataSet is empty. More responsive on dataset open. New event
460 OnRestorePosition. Column sort disabled if no header row.
461
462 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
463 while dataset state is dsInsert. Avoids posting errors.
464
465 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
466 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
467
468 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
469
470 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
471 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
472 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
473 always "posts" the current record regardless or whether or not it may be more appropriate
474 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
475 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
476 as the first action of the "Post" method and allows the handler to convert the Post
477 into a Cancel if that is the appropriate action on moving to a different row. This is
478 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
479 raised here, but it may still be more appropriate to validate a post and signal
480 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
481
482 15. On Unix derived systems, the Firebird library name can now be given as a colon
483 separated list. Each library name on the list is tried in turn, in left to right
484 order with the first found being used as the firebird library. By default, on Linux,
485 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
486 overidden by the FBLIB environment variable or the OnGetLibraryName function.
487
488 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
489 then it will still attempt to access the database via the Firebird Server and will
490 require a username and password. If only the pathname is given, then the username
491 and password should be omitted and the unix file permissions are used to grant
492 access.

494 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
495
496 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
497 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
498 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
499 corresponds to a row of the linked DataSource. Any data aware control on the
500 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
501
502 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
503 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
504 takes place during database access. This may be useful when there are performance issues with
505 the change of cursor. Setting the property to false suppresses the change of cursor.
506
507 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
508 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
509 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
510 making all changes permanent immediately rather than when the transaction is explicitly
511 committed.
512
513 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
514 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

520 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
521
522 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
523 This is typically used during an "OnBeforeOpen" event handler to manipulate the
524 "Where" and "Having" clauses to implement user specified filters of arbitrary
525 complexity.
526
527 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
528 three new data aware controls dependent on IBX and which make use of the SQL Parser.
529 These are:
530
531 - TIBLookupComboEditBox
532 - TIBDynamicGrid
533 - TIBTreeview
534
535 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
536 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
537 to revise the available list and restrict it to items that are prefixed by the
538 typed text (either case sensitive or case insensitive). Autoinsert allows a
539 newly typed entry to be added to the list dataset and included in the available
540 list items.
541
542 TIBDynamicGrid is a TDBGrid descendent that provides for:
543 - automatic resizing of selected columns to fill the available row length
544 - automatic positioning and sizing of a "totals" control, typically at the
545 column footer, on a per column basis.
546 - DataSet resorting on header row click, sorting the dataset by the selected column.
547 A second click on the same header cell reversed the sort order.
548 - Support for a "Panel Editor". That is on clicking the indicator column, the row
549 is automatically expanded and a panel superimposed on it. The panel can have any
550 number of child controls, typically data aware controls with the same datasource
551 as the grid allowing for editing of additional fields and more complex editors.
552 - Reselection of the same row following resorting.
553 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
554 Its properties are specified on a per column basis and allows for one or more
555 columns to have their values selected from a list provided by a dataset.
556 Autocomplete and autoinsert are also available. The existing picklist editor
557 is unaffected by the extension.
558
559 TIBTreeView is a data aware TCustomTreeView.
560
561 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
562 zero scale will no longer return an error. An Int64 will be returned instead.
563
564 4. TIBTransaction now has events for Before and After Transaction End and a new function
565 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
566
567 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
568 repeated multiple times.
569
570 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
571 check used to get in the way of using Stored Procedures, and "Update or Insert"
572 statements.
573
574 7. Insert, Modify and Delete property Editors now support Query Generation from
575 Stored Procedures.
576
577 8. Three new examples illustrate the use of the new IB Controls
578

580 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
581
582 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
583 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
584 Gabor Boros for reporting this problem and for testing the improvements).
585
586 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
587 See readme.field+param.names in the doc folder.
588
589 3. IBX SQL Editors will now automatically add double quotes around column names when the database
590 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
591
592 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
593
594 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
595 actions.
596
597 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
598 thanks to Yuriy Kopnin for pointing this out).
599
600 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
601
602 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
603 for both fields and parameter setting.
604
605 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
606 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
607
608 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
609 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
610
611 11. TIBTable now has a property editor for "MasterFields"
612
613 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
614 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
615
616 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
617 of settings is unrecognised. Selecting this radio button has no effect on the settings.

620 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
621
622 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
623
624 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
625
626 1. In a TIBCustomDataset descendent, a generator now only sets the value when
627 it is null. This allows for alternative user defined setting of the generator
628
629 Many thanks to Julio Jiménez for this fix
630
631 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
632 and suggests that the user may have forgotten to install it.
633
634 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
635
636 1. Conditional compilation used to limit registration of TIntegerField to
637 Lazarus versions less than 1.1
638
639 2. When a database connection is created, character set is now by default set
640 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
641 1250 to 1254.
642
643
644 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
645
646 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
647
648
649 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
650
651 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
652 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
653
654 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
655 package is changed to do this (which it should do).
656
657 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
658
659 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
660
661 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
662
663 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
664
665 4. Property editors should now correctly resize.
666
667 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
668 (restored original functionality)
669
670 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
671 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
