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

482 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
483
484 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
485 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
486 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
487 corresponds to a row of the linked DataSource. Any data aware control on the
488 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
489
490 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
491 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
492 takes place during database access. This may be useful when there are performance issues with
493 the change of cursor. Setting the property to false suppresses the change of cursor.
494
495 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
496 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
497 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
498 making all changes permanent immediately rather than when the transaction is explicitly
499 committed.
500
501 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
502 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

505
506 Development version only.
507
508 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
509
510 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
511 This is typically used during an "OnBeforeOpen" event handler to manipulate the
512 "Where" and "Having" clauses to implement user specified filters of arbitrary
513 complexity.
514
515 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
516 three new data aware controls dependent on IBX and which make use of the SQL Parser.
517 These are:
518
519 - TIBLookupComboEditBox
520 - TIBDynamicGrid
521 - TIBTreeview
522
523 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
524 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
525 to revise the available list and restrict it to items that are prefixed by the
526 typed text (either case sensitive or case insensitive). Autoinsert allows a
527 newly typed entry to be added to the list dataset and included in the available
528 list items.
529
530 TIBDynamicGrid is a TDBGrid descendent that provides for:
531 - automatic resizing of selected columns to fill the available row length
532 - automatic positioning and sizing of a "totals" control, typically at the
533 column footer, on a per column basis.
534 - DataSet resorting on header row click, sorting the dataset by the selected column.
535 A second click on the same header cell reversed the sort order.
536 - Support for a "Panel Editor". That is on clicking the indicator column, the row
537 is automatically expanded and a panel superimposed on it. The panel can have any
538 number of child controls, typically data aware controls with the same datasource
539 as the grid allowing for editing of additional fields and more complex editors.
540 - Reselection of the same row following resorting.
541 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
542 Its properties are specified on a per column basis and allows for one or more
543 columns to have their values selected from a list provided by a dataset.
544 Autocomplete and autoinsert are also available. The existing picklist editor
545 is unaffected by the extension.
546
547 TIBTreeView is a data aware TCustomTreeView.
548
549 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
550 zero scale will no longer return an error. An Int64 will be returned instead.
551
552 4. TIBTransaction now has events for Before and After Transaction End and a new function
553 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
554
555 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
556 repeated multiple times.
557
558 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
559 check used to get in the way of using Stored Procedures, and "Update or Insert"
560 statements.
561
562 7. Insert, Modify and Delete property Editors now support Query Generation from
563 Stored Procedures.
564
565 8. Three new examples illustrate the use of the new IB Controls
566
567
568 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
569
570 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
571 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
572 Gabor Boros for reporting this problem and for testing the improvements).
573
574 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
575 See readme.field+param.names in the doc folder.
576
577 3. IBX SQL Editors will now automatically add double quotes around column names when the database
578 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
579
580 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
581
582 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
583 actions.
584
585 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
586 thanks to Yuriy Kopnin for pointing this out).
587
588 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
589
590 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
591 for both fields and parameter setting.
592
593 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
594 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
595
596 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
597 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
598
599 11. TIBTable now has a property editor for "MasterFields"
600
601 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
602 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
603
604 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
605 of settings is unrecognised. Selecting this radio button has no effect on the settings.

608 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
609
610 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
611
612 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
613
614 1. In a TIBCustomDataset descendent, a generator now only sets the value when
615 it is null. This allows for alternative user defined setting of the generator
616
617 Many thanks to Julio Jiménez for this fix
618
619 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
620 and suggests that the user may have forgotten to install it.
621
622 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
623
624 1. Conditional compilation used to limit registration of TIntegerField to
625 Lazarus versions less than 1.1
626
627 2. When a database connection is created, character set is now by default set
628 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
629 1250 to 1254.
630
631
632 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
633
634 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
635
636
637 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
638
639 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
640 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
641
642 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
643 package is changed to do this (which it should do).
644
645 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
646
647 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
648
649 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
650
651 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
652
653 4. Property editors should now correctly resize.
654
655 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
656 (restored original functionality)
657
658 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
659 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
