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

466 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
467
468 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
469 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
470 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
471 corresponds to a row of the linked DataSource. Any data aware control on the
472 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
473
474 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
475 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
476 takes place during database access. This may be useful when there are performance issues with
477 the change of cursor. Setting the property to false suppresses the change of cursor.
478
479 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
480 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
481 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
482 making all changes permanent immediately rather than when the transaction is explicitly
483 committed.
484
485 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
486 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

492 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
493
494 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
495 This is typically used during an "OnBeforeOpen" event handler to manipulate the
496 "Where" and "Having" clauses to implement user specified filters of arbitrary
497 complexity.
498
499 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
500 three new data aware controls dependent on IBX and which make use of the SQL Parser.
501 These are:
502
503 - TIBLookupComboEditBox
504 - TIBDynamicGrid
505 - TIBTreeview
506
507 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
508 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
509 to revise the available list and restrict it to items that are prefixed by the
510 typed text (either case sensitive or case insensitive). Autoinsert allows a
511 newly typed entry to be added to the list dataset and included in the available
512 list items.
513
514 TIBDynamicGrid is a TDBGrid descendent that provides for:
515 - automatic resizing of selected columns to fill the available row length
516 - automatic positioning and sizing of a "totals" control, typically at the
517 column footer, on a per column basis.
518 - DataSet resorting on header row click, sorting the dataset by the selected column.
519 A second click on the same header cell reversed the sort order.
520 - Support for a "Panel Editor". That is on clicking the indicator column, the row
521 is automatically expanded and a panel superimposed on it. The panel can have any
522 number of child controls, typically data aware controls with the same datasource
523 as the grid allowing for editing of additional fields and more complex editors.
524 - Reselection of the same row following resorting.
525 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
526 Its properties are specified on a per column basis and allows for one or more
527 columns to have their values selected from a list provided by a dataset.
528 Autocomplete and autoinsert are also available. The existing picklist editor
529 is unaffected by the extension.
530
531 TIBTreeView is a data aware TCustomTreeView.
532
533 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
534 zero scale will no longer return an error. An Int64 will be returned instead.
535
536 4. TIBTransaction now has events for Before and After Transaction End and a new function
537 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
538
539 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
540 repeated multiple times.
541
542 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
543 check used to get in the way of using Stored Procedures, and "Update or Insert"
544 statements.
545
546 7. Insert, Modify and Delete property Editors now support Query Generation from
547 Stored Procedures.
548
549 8. Three new examples illustrate the use of the new IB Controls
550
551
552 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
553
554 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
555 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
556 Gabor Boros for reporting this problem and for testing the improvements).
557
558 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
559 See readme.field+param.names in the doc folder.
560
561 3. IBX SQL Editors will now automatically add double quotes around column names when the database
562 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
563
564 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
565
566 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
567 actions.
568
569 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
570 thanks to Yuriy Kopnin for pointing this out).
571
572 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
573
574 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
575 for both fields and parameter setting.
576
577 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
578 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
579
580 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
581 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
582
583 11. TIBTable now has a property editor for "MasterFields"
584
585 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
586 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
587
588 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
589 of settings is unrecognised. Selecting this radio button has no effect on the settings.

592 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
593
594 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
595
596 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
597
598 1. In a TIBCustomDataset descendent, a generator now only sets the value when
599 it is null. This allows for alternative user defined setting of the generator
600
601 Many thanks to Julio Jiménez for this fix
602
603 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
604 and suggests that the user may have forgotten to install it.
605
606 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
607
608 1. Conditional compilation used to limit registration of TIntegerField to
609 Lazarus versions less than 1.1
610
611 2. When a database connection is created, character set is now by default set
612 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
613 1250 to 1254.
614
615
616 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
617
618 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
619
620
621 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
622
623 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
624 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
625
626 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
627 package is changed to do this (which it should do).
628
629 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
630
631 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
632
633 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
634
635 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
636
637 4. Property editors should now correctly resize.
638
639 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
640 (restored original functionality)
641
642 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
643 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
