3
4 See also doc/readme.upgrade-4-x.to.2-0-0.xhtml for important information on
5 upgrading to IBX2.
6
7 1. Size property of TIBStringField is now the width in characters of the field
8 and not the byte length. This applies only to multi-byte character sets such
9 as UTF8. The original approach aligned with TStringField. However, the TStringField
10 code is not recognised as a bug and hence this change to align the behaviour.
11 The TStringField change is expected in fpc 3.2.0.
12
13 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
14 true (default) then Size property value saved in the lfm is ignored. Size is
15 always set from the dynamic information read from the database. It is unclear
16 why anyone would want to override this and set Size to false.
17
18 3. ibxscript: should now handle correctly a Case..End statement within a procedure
19 block.
20
21 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
22 exist when an attempt is made to connect to it (run time only) then an attempt
23 is made to create the database.
24
25 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
26 has been successfully created as a result of a call to CreateDatabase or when
27 creating a database after it was found not to exist.
28
29 6. DBControlGrid: a race condition could result in the wrong row image being
30 written to the cache. This has been avoided by a trip round the message
31 loop before rendering the row image.
32
33 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
34 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
35 known to risk corrupt rendering of row images when the control is first
36 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
37 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
38
39 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
40 a TDateEdit control located on an editor panel.
41
42 9. TIBExtract: brought up-to-date plus many bug fixes.
43
44 10. DBControlGrid: Removed memory leak when updating rows.
45
46 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
47
48 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
49
50 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
51 when target codepage is CP_NONE. This is a workaround for
52 http://bugs.freepascal.org/view.php?id=30622.
53
54 2. DBLog option removed from TIBStatisticalService - not supported by server
55 since Firebird 1.5.
56
57 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
58 similar.
59
60 4. IBCodePage: updated mapping between codepages and character id.
61
62 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
63 Firebird. Character sets with a char width of two are not UTF16.
64
65 6. Strings received from the database are now always transliterated into UTF8
66 regardless of the database character set or connection character set. This
67 is for compatibility with the LCL.
68
69 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
70
71 1. IBBlob: Defer reading of blob until read method called. This avoids having to
72 read in an entire blob just to get the size of the blob. General performance
73 improvement when opening datasets containing blobs.
74
75 2. Clearing a Blob now sets the corresponding field's modified flag.
76
77 3. IBLookupCombo: When not performing auto-complete, original query sort order
78 is now used.
79
80 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
81 determined.
82
83 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
84
85 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
86 lazarus 1.6.0
87
88 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
89 compilation error.
90
91 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
92
93 1. No character set specified for connection: when a text blob is retrieved, the
94 character set is determined by looking up the native character set using then
95 Firebird API. Otherwise a text mode blob is assumed to have the same character
96 set as the connection.
97
98 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
99 for Login Dialog returing a change to the database path.
100
101 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
102 to be changed from that given in the TIBDatabase/TIBServer component and for the
103 entered value to be saved on a project specific basis (design time only).
104
105 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
106 column fieldname. If they are the same then it is acts as a look up for the KeyValue
107 Otherwise, it sets the column text to the selected ListField Value.
108
109 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
110 column width.
111
112 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
113 and a case insensitive search is requested.
114
115 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
116 or column ListSource.
117
118 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
119 unprepare) when closing and the text has not changed.
120
121 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
122 Less likely to cause a cursor re-use error on Windows.
123
124 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
125 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
126
127 11. TIBTreeView: Guard against nil destination on record changed
128
129 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
130 string type with the code page set to reflect the returned field encoding after
131 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
132 earlier versions.
133
134 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
135 will now result in transliteration to the code page specified for the Firebird driver
136 if the assigned string has a different code page. FPC 3.0.0 onwards only.
137
138 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
139 is ignored and the lc_ctype value, when the database is opened, is set to align with
140 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
141 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
142 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
143 the GETACP is used to determine the Windows code page.
144
145 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
146 name used as the lc_ctype when the database was opened. Only valid while the
147 Database is connected.
148
149 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
150 id that corresponds to the DefaultCharSetName.
151
152 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
153
154 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
155 path is given and database attach fails due to access permission issues on the
156 temp directory or security database, then the attach is retried with "localhost:"
157 prefixing the databasename. This should avoid problems when the database has to
158 be accessed by a local (e.g. classic) server and libfbembed is used.
159
160 2. Windows: revised search order for Firebird DLL:
161 i. The Firebird Embedded Server in the application Directory.
162 ii. If the FIREBIRD environment variable is set then the directory this
163 points to is searched for the FB Client DLL and then then underlying
164 "bin" directory.
165 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
166 is used to locate the Firebird installation directory and the underlying
167 "bin" directory is searched for the FB Client DLL.
168 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
169 are searched for the FB Client DLL.
170 v. The PATH Environment variable is used to search for the FB Client DLL.
171 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
172
173 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
174 See doc/readme.scriptengine and example applications.
175
176 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
177 simplify the use of the embedded firebird server on both Linux and Windows platforms.
178 See dpc/readme.localdatabase and example applications.
179
180 5. IBDynamicGrid: Reordering on column header click should now also work for
181 dynamic columns.
182
183 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
184 between incrementing/decrementing the lock count and signalling the event.
185
186 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
187
188 1.3.2 was never formally released and only made available as beta copies.
189
190 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
191
192 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
193
194 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
195
196 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
197 i.e. when it is a calculated field
198
199 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
200 This problem was due to a race condition between recalculating row heights and
201 determining which row was selected by the mouse click. The row height calculation
202 is now deferred by an extra trip round the message loop allowing the row to
203 be always calculated on the current grid layout rather than risking it being
204 calculated on the grid layout after the expanded row has been shrunk.
205
206 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
207 Windows.
208
209 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
210 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
211 to be determined at runtime. See doc/readme.charactersets.html.
212
213 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
214 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
215
216 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
217 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
218 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
219
220 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
221 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
222 implies no truncation.
223
224 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
225
226 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
227 (avoids "Not in Edit Mode" error).
228
229 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
230
231 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
232 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
233
234 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
235
236 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
237
238 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
239
240 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
241
242 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
243
244 1. OnCloseUp Event Handler added to TDBLookupProperties
245
246 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
247 problem with row size when exception is called.
248
249 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
250
251 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
252 in a TCustomComboBox and ignores return key if in a TCustomMemo
253
254 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
255 keyed in i.e. when autocomplete not performed
256
257 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
258 console mode applications with all LCL required functions (builtin dialogs and
259 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
260 not included in your project, IBX should compile and link with a console mode program.
261 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
262 console mode application or the IDE will automatically assume that your
263 application is GUI based. Instead, you should include the ibexpressconsolemode package.
264
265 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
266 to use the built in dialogs and cursor management. IBDialogs is
267 included by default if "ibexpress" is in your project source's "uses" clause.
268 This should be the case for all projects created through the IDE. This is why
269 you do not want to add the ibexpress package to console mode applications. The
270 ibexpressconsolemode package has been created to allow console mode programs
271 to avoid adding LCL dependencies when using IBX, while still having the
272 unit search paths set up correctly.
273
274 Existing users should check to ensure that the "ibexpress" unit is included in
275 each project's source file (*.lpr).
276
277 You may find that in order for the IDE to recognise that ibexpressconsolemode
278 exists, you have to first open the package in the IDE and then close it. This
279 adds it to the most recently accessed packages list. To make it permanently
280 available, add the package name to lazarus' staticpackages.inc file.
281
282 Thanks to Julio Jiménez for suggesting support of console mode.
283
284 7. SQL Parser can now accept quoted strings that include new lines
285
286 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
287 of text on start of edit. This is particularly useful when tabbing to a
288 column and then inserting text.
289
290 9. New Examples provided for IB Services and ISQLMonitor.
291
292 10. Fix error when writing to blob streams that recorded only the last buffer
293 write in the blob stream. In most cases, this did not cause a problem as the
294 IB Blob Stream is written in a single write. However, with the TDBImage, write
295 of a graphic type prefix was lost which caused a problem when the image could
296 not be automatically recognised.
297
298 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
299 already open" errors due to random numbers used for the cursor name being identical.
300
301 12. IBTable: corrected error that could result in an "Index out of bounds" error
302 when opening the table and the Primary Key is the last or only column in the
303 table. Thanks to Rick Hoover for the fix.
304
305 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
306 of "UTF-8", and update list of available database character sets. Existing
307 users should check the current lc_ctype setting in their applications.
308
309 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
310
311 1. Firebird Services: avoid List Index error when opening a service with an
312 empty Params property.
313
314 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
315 Link now set up in Loaded method - avoids occasional failure to apply
316 SQL markup on initial open.
317
318 3. "Employees" example performance improvements when scrolling.
319
320 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
321 TFrame. Force recaching of selected frame to avoid GTK race (results in a
322 random image cached).
323
324 5. DBControlGrid: Should now react to changes in panel height at run time.
325
326 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
327 even when further rows exist.
328
329 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
330 always be derived from panel height and setting this property can cause confusion.
331 Note for existing projects: to avoid a missing property error at run time,
332 each form using the DBControlGrid must be opened, updated and saved in the IDE
333 in order to remove the property value from the lfm.
334
335
336 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
337
338 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
339 call Prepare before setting parameter values.
340
341 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
342
343 3. Code tidyup and more robust handling of dsql information result vector.
344
345 4. Support for centralised handling of transaction status changes. TIBTransaction
346 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
347 and "AfterExecQuery". The first three are called after the same event is called
348 for an IBCustomDataSet descendent using the Transaction. The fourth is called
349 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
350 enable monitoring of transaction status changes for a given transaction to be
351 handled in a single place. For example, when a change to the dataset occurs
352 an indicator can be set that shows the user that in order to save changes,
353 the transaction should be committed. Rather than doing this per dataset, this
354 can now be done per transaction.
355
356 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
357 the dataset is scrolled. However, any changes to the current row are, by default,
358 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
359 have a new property "DataSetCloseAction" that adds automatic posting of changes
360 on dataset close. If this property is set to dcDiscardChanges (default) then the
361 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
362 then IBX will attempt to post any unsaved changes before the dataset is closed
363 (and after the BeforeClose event handler is called). The exception is when the
364 dataset is being closed as a result of a transaction rollback. In this case,
365 no action is taken and any unsaved changes are discarded. This avoids both
366 unnecessary overhead and the risk that a validation error may occur in the Post
367 raising an exception and thereby preventing a rollback.
368
369 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
370 In earlier versions, the Display Width was set to the maximum byte width rather than the character
371 width. Display Widths are now corrected by dividing by the max byte width per character.
372 For UTF8 character sets, the byte width is four and hence the Display Width will be
373 the byte width divided by 4. The byte width of each character set is determined
374 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
375 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
376
377 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
378
379 8. IBLookupComboEditBox: List should now always be restored to full list when the
380 control loses focus. Default Key press default interval reduced to 200ms.
381
382 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
383 when dataset rows are less than visible rows.
384
385 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
386 does not exist or DataSet is empty. More responsive on dataset open. New event
387 OnRestorePosition. Column sort disabled if no header row.
388
389 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
390 while dataset state is dsInsert. Avoids posting errors.
391
392 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
393 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
394
395 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
396
397 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
398 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
399 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
400 always "posts" the current record regardless or whether or not it may be more appropriate
401 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
402 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
403 as the first action of the "Post" method and allows the handler to convert the Post
404 into a Cancel if that is the appropriate action on moving to a different row. This is
405 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
406 raised here, but it may still be more appropriate to validate a post and signal
407 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
408
409 15. On Unix derived systems, the Firebird library name can now be given as a colon
410 separated list. Each library name on the list is tried in turn, in left to right
411 order with the first found being used as the firebird library. By default, on Linux,
412 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
413 overidden by the FBLIB environment variable or the OnGetLibraryName function.
414
415 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
416 then it will still attempt to access the database via the Firebird Server and will
417 require a username and password. If only the pathname is given, then the username
418 and password should be omitted and the unix file permissions are used to grant
419 access.
420
421 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
422
423 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
424 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
425 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
426 corresponds to a row of the linked DataSource. Any data aware control on the
427 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
428
429 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
430 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
431 takes place during database access. This may be useful when there are performance issues with
432 the change of cursor. Setting the property to false suppresses the change of cursor.
433
434 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
435 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
436 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
437 making all changes permanent immediately rather than when the transaction is explicitly
438 committed.
439
440 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still

447 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
448
449 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
450 This is typically used during an "OnBeforeOpen" event handler to manipulate the
451 "Where" and "Having" clauses to implement user specified filters of arbitrary
452 complexity.
453
454 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
455 three new data aware controls dependent on IBX and which make use of the SQL Parser.
456 These are:
457
458 - TIBLookupComboEditBox
459 - TIBDynamicGrid
460 - TIBTreeview
461
462 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
463 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
464 to revise the available list and restrict it to items that are prefixed by the
465 typed text (either case sensitive or case insensitive). Autoinsert allows a
466 newly typed entry to be added to the list dataset and included in the available
467 list items.
468
469 TIBDynamicGrid is a TDBGrid descendent that provides for:
470 - automatic resizing of selected columns to fill the available row length
471 - automatic positioning and sizing of a "totals" control, typically at the
472 column footer, on a per column basis.
473 - DataSet resorting on header row click, sorting the dataset by the selected column.
474 A second click on the same header cell reversed the sort order.
475 - Support for a "Panel Editor". That is on clicking the indicator column, the row
476 is automatically expanded and a panel superimposed on it. The panel can have any
477 number of child controls, typically data aware controls with the same datasource
478 as the grid allowing for editing of additional fields and more complex editors.
479 - Reselection of the same row following resorting.
480 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
481 Its properties are specified on a per column basis and allows for one or more
482 columns to have their values selected from a list provided by a dataset.
483 Autocomplete and autoinsert are also available. The existing picklist editor
484 is unaffected by the extension.
485
486 TIBTreeView is a data aware TCustomTreeView.
487
488 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
489 zero scale will no longer return an error. An Int64 will be returned instead.
490
491 4. TIBTransaction now has events for Before and After Transaction End and a new function
492 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
493
494 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
495 repeated multiple times.
496
497 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
498 check used to get in the way of using Stored Procedures, and "Update or Insert"
499 statements.
500
501 7. Insert, Modify and Delete property Editors now support Query Generation from
502 Stored Procedures.
503
504 8. Three new examples illustrate the use of the new IB Controls

507 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
508
509 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
510 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
511 Gabor Boros for reporting this problem and for testing the improvements).
512
513 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
514 See readme.field+param.names in the doc folder.
515
516 3. IBX SQL Editors will now automatically add double quotes around column names when the database
517 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
518
519 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
520
521 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
522 actions.
523
524 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
525 thanks to Yuriy Kopnin for pointing this out).
526
527 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
528
529 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
530 for both fields and parameter setting.
531
532 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
533 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
534
535 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
536 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
537
538 11. TIBTable now has a property editor for "MasterFields"
539
540 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
541 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
542
543 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
544 of settings is unrecognised. Selecting this radio button has no effect on the settings.

547 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
548
549 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
550
551 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
552
553 1. In a TIBCustomDataset descendent, a generator now only sets the value when
554 it is null. This allows for alternative user defined setting of the generator
555
556 Many thanks to Julio Jiménez for this fix
557
558 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
559 and suggests that the user may have forgotten to install it.
560
561 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
562
563 1. Conditional compilation used to limit registration of TIntegerField to
564 Lazarus versions less than 1.1
565
566 2. When a database connection is created, character set is now by default set
567 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
568 1250 to 1254.
569
570
571 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
572
573 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
574
575
576 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
577
578 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
579 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
580
581 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
582 package is changed to do this (which it should do).
583
584 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
585
586 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
587
588 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
589
590 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
591
592 4. Property editors should now correctly resize.
593
594 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
595 (restored original functionality)
596
597 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
598 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
