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

491 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
492
493 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
494 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
495 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
496 corresponds to a row of the linked DataSource. Any data aware control on the
497 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
498
499 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
500 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
501 takes place during database access. This may be useful when there are performance issues with
502 the change of cursor. Setting the property to false suppresses the change of cursor.
503
504 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
505 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
506 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
507 making all changes permanent immediately rather than when the transaction is explicitly
508 committed.
509
510 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
511 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

517 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
518
519 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
520 This is typically used during an "OnBeforeOpen" event handler to manipulate the
521 "Where" and "Having" clauses to implement user specified filters of arbitrary
522 complexity.
523
524 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
525 three new data aware controls dependent on IBX and which make use of the SQL Parser.
526 These are:
527
528 - TIBLookupComboEditBox
529 - TIBDynamicGrid
530 - TIBTreeview
531
532 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
533 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
534 to revise the available list and restrict it to items that are prefixed by the
535 typed text (either case sensitive or case insensitive). Autoinsert allows a
536 newly typed entry to be added to the list dataset and included in the available
537 list items.
538
539 TIBDynamicGrid is a TDBGrid descendent that provides for:
540 - automatic resizing of selected columns to fill the available row length
541 - automatic positioning and sizing of a "totals" control, typically at the
542 column footer, on a per column basis.
543 - DataSet resorting on header row click, sorting the dataset by the selected column.
544 A second click on the same header cell reversed the sort order.
545 - Support for a "Panel Editor". That is on clicking the indicator column, the row
546 is automatically expanded and a panel superimposed on it. The panel can have any
547 number of child controls, typically data aware controls with the same datasource
548 as the grid allowing for editing of additional fields and more complex editors.
549 - Reselection of the same row following resorting.
550 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
551 Its properties are specified on a per column basis and allows for one or more
552 columns to have their values selected from a list provided by a dataset.
553 Autocomplete and autoinsert are also available. The existing picklist editor
554 is unaffected by the extension.
555
556 TIBTreeView is a data aware TCustomTreeView.
557
558 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
559 zero scale will no longer return an error. An Int64 will be returned instead.
560
561 4. TIBTransaction now has events for Before and After Transaction End and a new function
562 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
563
564 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
565 repeated multiple times.
566
567 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
568 check used to get in the way of using Stored Procedures, and "Update or Insert"
569 statements.
570
571 7. Insert, Modify and Delete property Editors now support Query Generation from
572 Stored Procedures.
573
574 8. Three new examples illustrate the use of the new IB Controls
575

577 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
578
579 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
580 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
581 Gabor Boros for reporting this problem and for testing the improvements).
582
583 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
584 See readme.field+param.names in the doc folder.
585
586 3. IBX SQL Editors will now automatically add double quotes around column names when the database
587 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
588
589 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
590
591 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
592 actions.
593
594 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
595 thanks to Yuriy Kopnin for pointing this out).
596
597 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
598
599 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
600 for both fields and parameter setting.
601
602 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
603 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
604
605 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
606 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
607
608 11. TIBTable now has a property editor for "MasterFields"
609
610 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
611 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
612
613 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
614 of settings is unrecognised. Selecting this radio button has no effect on the settings.

617 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
618
619 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
620
621 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
622
623 1. In a TIBCustomDataset descendent, a generator now only sets the value when
624 it is null. This allows for alternative user defined setting of the generator
625
626 Many thanks to Julio Jiménez for this fix
627
628 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
629 and suggests that the user may have forgotten to install it.
630
631 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
632
633 1. Conditional compilation used to limit registration of TIntegerField to
634 Lazarus versions less than 1.1
635
636 2. When a database connection is created, character set is now by default set
637 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
638 1250 to 1254.
639
640
641 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
642
643 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
644
645
646 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
647
648 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
649 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
650
651 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
652 package is changed to do this (which it should do).
653
654 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
655
656 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
657
658 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
659
660 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
661
662 4. Property editors should now correctly resize.
663
664 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
665 (restored original functionality)
666
667 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
668 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
