1 IBX Change Log version (2.6-4 Build 14188) Mon, 08 Jan 2024 15:20:50 +0000
2
3 1. TIBCustomDataSet.ApplyUpdates: ensure controls are not permanently disabled
4 if ApplyUpdates called before a cursor exists.
5
6 2. TIBCustomDataSet.CreateBlobStream: add check for empty dataset before
7 creating the blob.
8
9 3. TIBCustomDataset.Requery: The display buffer pool is now also reset avoiding
10 issues with left over pointers to invalid internal buffers.
11
12 4. TIBCustomDataset.PrimaryKeys when used in InternalRefresh. when more than one
13 primary key is used by the dataset then the list of primary keys is now
14 properly separated by a ';'.
15
16 5. When refresh is called for a dataset without any primary keys (e.g. views and
17 stored procedures), the internal record number is now used to restore the cursor
18 following the refresh. However, it should be noted that cannot be 100% reliable.
19 The internal record number simply reflects the record fetch order and this can
20 change between successive queries if records are inserted or deleted by the
21 current or another user (if the read_committed transaction isolation level is used).
22
23 6. Inserting a record at the start of a grid and then resizing the grid should
24 no longer result in an apparent duplication of records in the grid. Note: this
25 was due to TDataset.SetCurrentRecord ignoring the bookmark flag (bfInserted). IBX
26 works around this by no longer using this bookmark flag value.
27
28 7. Inserting a record into an empty grid and then resizing the grid should
29 no longer result in an apparent duplication of records in the grid.
30
31 8. IBBufferedCursor. FCurrentRecordStatus now set correctly when selecting a
32 specific record number.
33
34 9. IBCustomDataset: Calls to AfterScroll during a Locate operation are now suppressed
35 until the end of the locate operation.
36
37 10.IBCustomDataset: Calls to BeforeScroll during a Locate operation are now suppressed.
38 BeforeScroll is called once before the locate operation.
39
40 IBX Change Log version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100
41
42 1. Update to calls to EInterbaseError to add default code page. Consequential
43 on change to fbintf.
44
45 2. Update some examples to replace test for null date with the NullDate constant
46 instead of zero. This is because Laz 3.0 changes the value of NullDate.
47
48 IBX Change Log version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100
49
50 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
51 with later versions of fpc - later than 3.2.2.
52
53 2. IBUpdateSQL. update internal queries if parent dataset database changed.
54
55 3. IBUpdateSQL: Do not prepare an empty internal query.
56
57 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
58
59 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
60
61 IBX Change Log version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
62
63 1. Maintenance update of 2.6.0. This version is still at beta.
64
65 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
66 See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
67
68 3. ibxscript: When parsing a store procedure or function with a variable name
69 enclosed in doublequotes, the double quotes are no longer removed.
70
71 IBX Change Log version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
72
73 NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
74 AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
75 BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
76 ISSUES TO support@mwasoftware.co.uk
77
78 1. Complete rewrite of internal buffer management in order to improve performance
79 and maintainability. Highlights:
80
81 * Extending the size of the buffer pool no longer has to copy the entire record
82 cache. Instead, a new extent is simply added to the buffer pool.
83 * A memory to memory copy of each display buffer now is avoided when scolling the
84 dataset.
85 * A separate set of buffers is now used for calculated fields. This avoids
86 having to keep copies of calculated field values in the buffer cache.
87 * Compact bitmaps are used to record null status and need to refresh in each
88 buffer.
89 * Display buffer type changed from PChar to TRecordBuffer in line with change of
90 buffer type in FCL-DB.
91
92 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
93 to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
94
95 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
96 If either or both of these flags are set at design time (using the fields editor)
97 then this forces a row refresh on respectively insert or update, or both, when the
98 corresponding field is not present in an SQL RETURNING clause.
99
100 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
101 maintainability and readability and to add identification of primary key fields.
102
103 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
104 as a refresh of the current row. However, this is different behaviour to that described
105 in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
106 the dataset from the underlying database, and attempts to reposition the cursor on
107 the same record as it was". IBX now complies with the FPC definition of Refresh.
108
109 6. A progammatic Row Refresh should no longer be required.
110 Use Insert/Update... returning to refresh any fields that may change following an
111 insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
112 on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
113 for the field at Design Time to force a row refresh if not in the returning clause.
114
115 7. It should now be possible to insert a row into an empty unidirectional dataset.
116
117 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
118 This gives the number of buffers in the initial block for the buffer pool in
119 bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
120 in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
121 for small datasets.
122
123 IBX Change Log version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
124
125 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
126
127 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
128
129 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
130
131 IBX Change Log version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
132
133 1. TIBTransaction: new properties
134 property TransactionID: integer read GetTransactionID;
135 property IsReadOnly: boolean read GetIsReadOnly;
136 {published}
137 property TransactionName: string read FTransactionName write SetTransactionName;
138
139 2. IBCustomDataset: per row blob and array buffer cached clear before processing
140 Insert or Update...Returning. This allows blobs and arrays to be returned
141 by the statement.
142
143 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
144
145 4. TransactionName initialised to a newly generated GUID if empty.
146
147 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
148 for the fbintf package's journaling capability. TIBJournal is used to set the
149 file path and filename for the journal file and to Enabled (start journaling) and
150 disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
151 more information, and comments in IBJournal.pas.
152
153 6. TIBDatabase.InternalTransaction is now a read only transaction.
154
155 7. Bug fix: blob id no longer set to null on update when blob has not been
156 retrieved.
157
158 8. Row auto refreshed on update/insert if blob or array field updated and field
159 not in a returning clause.
160
161 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
162 buffer overhead and avoids problem when refresh query has a different column
163 count to select query i.e. incorrectly changing number of columns.
164
165 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
166
167 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
168 string. Note that the Version property returns an InterBase compatible version string.
169
170 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
171
172 IBX Change Log version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
173
174 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
175 This is for compatibility with Firebird 5 where Update...Returning can return
176 a cursor.
177
178 IBX Change Log version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
179
180 1. Add try-..except check when initially loading library in IDE. This should
181 ensure that IDE continues to load even when a failure occurs in IBX load
182 library.
183
184 2. IBXScript: now recognises a CASE...END block within a stored procedure and
185 hence will correctly detect end of the outer containing block when the block
186 contains a SELECT ... CASE ... END construct.
187
188 3. IBExtract: some further tidying up to remove extraneous white space.
189
190 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
191 errors when extra elements are added to DB.TFieldType.
192
193 5. IBUpdate: updated to reflect changes to ISQLParam.
194
195 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
196
197 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
198
199 8. IBSQL: Support for scrollable cursors added (note: local databases only)
200
201 IBX Change Log version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
202
203 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
204 exception of those defined to be one byte wide e.g. DBImplementationNo.
205
206 2. TIBSQL: Batch Update/Insert support added.
207
208 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
209 is no longer automatically converted to upper case when it is syntactically a
210 SQL Identifier. This is to support the use of stored procedures defined e.g.
211 as CREATE PROCEDURE "iCASE".
212
213 There could be a backwards compatibility issue when the StoredProcName was entered
214 manually at design time. That is not selected from the drop down list. If the
215 StoredProcName is entered in mixed case and the procedure was declared e.g. as
216 CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
217 ensure that the value of the StoredProcName is all upper case, unless it was
218 declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
219 quotes).
220
221 Note that when a stored procedure name was declared delimited in double quotes,
222 as in the first example above, the value of the StoredProcName property must not
223 include the delimiters (double quotes).
224
225 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
226 upgrade.conf was not found. This replaces silently ignoring the problem.
227
228 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
229 'Version.%.3d' and is used to generate the section header names (for a given
230 version no.) in the upgrade.conf file.
231
232 IBX Change Log version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
233
234 1. -c command line option added to fbsql example program. Used to set connection
235 character set.
236
237 IBX Change Log version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
238
239 1. Firebird 4 support added.
240
241 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
242 extended precision NUMERIC fields are supported.
243
244 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
245
246 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
247 and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
248
249 5. IBExtract now supports FB4 enhancements:
250 - new data types as above
251 - Identity column extensions
252 - Default user role
253 - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
254 - Internal Functions
255
256 6. IBExtract: new event: OnExtractLines.
257
258 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
259
260 8. IBXServices: Server version no. parsing now allows any letter before major version number
261 and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
262
263 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
264 format for rendering a time zone.
265
266 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
267 to convert TIME WITH TIME ZONE data type values to and from GMT.
268
269 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
270 IIBGUIInterface and IIBTimerInf respectively.
271
272 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
273 now accessible as properties of TIBDatabase and TIBTransaction respectively.
274
275 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
276 truncated to its fixed character width rather than being right padded with
277 white space to the maximum data size.
278
279 14. TIBTable.Empty table. In additional to deleting all records in the underlying
280 table, the internal buffers are now also flushed ensuring that the TIBTable is
281 also empty.
282
283 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
284
285 16. TIBXControlService descendents: DatabaseName may now be set using a database
286 connect string. The database name is extracted from the connect string.
287
288 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
289
290 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
291
292 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
293 not being present as required.
294
295 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
296 version that can be customised to work with other database drivers.
297
298 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
299 unnecessary CR at end of line on Unix platforms.
300
301 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
302 seconds in order to reduce risk of message loss.
303
304 23. ISQLMonitor: read and write count statistics now available via:
305 property TIBSQLMonitor.ReadCount;
306 IIBSQLMonitorHook.GetWriteCount: integer;
307
308 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
309
310 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
311
312 1. TIBStringField: when a string value is read from a dataset buffer, if the
313 number of UTF8 characters exceeds the string size then string is truncated
314 to the maximum string size. This is usually a problem with fixed width columns
315 right padded with white space.
316
317 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
318 If SQLFiltered is set then when a dataset is opened, each line in the
319 SQLFilterParams property is assumed to be a SQL condition clause and
320 ANDed into the Where clause of the SQL Select statement provided as a
321 dataset property. Each such SQL condition thus acts as an additional filter
322 on the dataset.
323
324 3. The Filtered property inherited from TDataset is no longer used for SQL (server
325 side filters).
326
327 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
328 text matches complete entry.
329
330 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
331 dataset are active (avoids risk of access violation if master is inactive)
332
333 6. TIBEvents: Registered property can now be set at design time even if database not open
334
335 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
336 This should prevent "spillover" of events between sessions.
337
338 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
339 This should ensure that the internal buffer is set up correctly and avoids
340 a duplicate initial row.
341
342 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
343 That is, the DataSize should be the field size * character set width. The
344 value returned by DataSize is now the same as the Dataset buffer size reserved
345 for the field.
346
347 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
348
349 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
350 and vice-versa. This may result in an exception being raised (correctly) for
351 older programs when using dataset fields added to a form and the database has been
352 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
353 In such cases, the field needs to be deleted in the IDE fields editor and then
354 added back in.
355
356 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
357 false if query contains only white space and not just empty.
358
359 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
360 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
361 is cancelled.
362
363 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
364 called on a null field.
365
366 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
367 results in an empty dataTC86 Client side Filtered Dataset 1 X
368 set.
369
370 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
371 a cached update is applied and an exception is raised.
372
373 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
374
375 17. Console Mode Local Database support: backup/restore should now work correctly.
376
377 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
378 possible and an exception raised.
379
380 19. MinimumVersionNo added to Local Database Support. Database will not open if
381 below this version no. and upgrade not possible.
382
383 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
384
385 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
386 not SQL Identifiers are now supported.
387
388 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
389 passed to the Firebird engine for execution.
390
391 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
392 is made to scroll back.
393
394 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
395
396 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
397 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
398
399 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
400 validated. If no match is found in the list of field names and the database has
401 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
402 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
403
404 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
405 with fpc 3.2.
406
407 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
408
409
410 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
411 and is used to override the default settings in the client side "firebird.conf" This
412 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
413 Each line of the string list should be a setting in the same format as "firebird.conf".
414 For example "WireCompression = true" in order to request wire compression on the client side.
415
416 Note: explicit settings in the client side "firebird.conf" appear to take precedence
417 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
418 also require a compatible setting in the server side "firebird.conf". For example
419 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
420 compression to be used.
421
422 Whether or not WireCompression or WireCrypt are in use can be checked using the information
423 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
424 ibx/examples/dbinfo for examples of how to display this information.
425
426 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
427 is a "convenience" property. If set the "WireCompression=true" is added to the
428 ConfigOverrides. If unchecked then this setting is removed.
429
430 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
431 not "INT64".
432
433 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
434 These are:
435 property TimestampFormat: string;
436 property DateFormat: string;
437 property TimeFormat: string;
438
439 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
440 DATETIME and TIME. The format strings use the standard FPC date/time format
441 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
442
443 If any of the above properties are set to an empty string, then the locale default
444 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
445 locale default is extended by appending '.zzz' to include milliseconds.
446
447 TIBCSVDataOut by default sets these properties to the empty string, while the other
448 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
449
450 5. New published property for TIBCSVDataOut:
451 property QuoteStrings: boolean (default true)
452
453 If false then strings are unquoted, otherwise, the QuoteChar property value is
454 used to delimit each and every string in the output.
455
456 6. New published properties for TIBCSVDataOut:
457 property FieldSeparator: string;
458 property HeaderSeparator: string;
459
460 Respectively, these provide the separator character(s) used to separate fields
461 in data and header rows. Both default to ','.
462
463 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
464 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
465 property OnFormatTextString;
466
467 This event handler can be used to process text strings before they are included
468 in the output e.g. to replace unprintable characters with alternative strings.
469 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
470
471 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
472 Uses "FindParam" if in order to find out if a parameter with a given name exists
473 and without raising and exception if it does not.
474
475 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
476 consistency with SQL queries.
477
478 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
479 When true, SQL statement parameter names are parsed case sensitive. Note for
480 TIBDataSet only applies to Select query.
481
482 11. IBEvents: removing a TIBEvent component from a form should no longer result in
483 an IDE exception.
484
485 12. LocalDBSupport: initial database creation should now work correctly
486 when the schema source is an sql file.
487
488 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
489 when defined, this handler will be called by the internal TIBXScript during
490 initial database creation when the schema source is an sql file and may be used
491 to provide a visual indication of progress in console mode.
492
493 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
494 to true while a new local database is being created and its schema populated.
495 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
496 when the database is disconnected/connected during the create DB procedure.
497
498 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
499 are now always ignored and replaced by the user name and password provided as
500 the login parameters for the TIBDatabase referenced from the TIBXScript. The
501 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
502 completely ignored if this property is true.
503
504 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
505 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
506 ImageIndex and SelectImageIndex values on AddNode.
507
508 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
509 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
510 the same database connection.
511
512 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
513 if provided, this should be an conditional SQL expression suitable for
514 including in an SQL Select statement "where" clause. If non-empty and the
515 "Filtered" property is true then the SQL expression provided as the value of
516 the "Filter" property is "ANDed" with any existing condition statement
517 in the SQL statement's "Where" clause.
518
519 If the "Filter" property is set at run time, the "Filtered" property is true
520 and the dataset is already open, then the dataset is closed and re-opened automatically.
521
522 The "Filter" condition may include IBX style parameters. In which case, their
523 value must be set by the dataset's "OnBeforeOpen" event handler.
524
525 This is a public property for TIBDataSet and TIBQuery query and intended for
526 use at run time.
527
528 Note: The property is a published property of TIBTable. The TIBTable functionality
529 is unaffected by this change.
530
531 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
532
533 1. Remove need to check for IsMultiThread by providing access to GUI timers via
534 IBGUIInterface. Note: master/detail delay timer does not apply to console
535 mode apps.
536
537 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
538 statement. This avoids problems if "Execute Block" is used as the Query.
539
540 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
541 internal SQL tokeniser routines.
542
543 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
544 as a select statement, with or without CTEs.
545
546 5. IBSQLParser: parser now recognises the "ROWS" clause.
547
548 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
549 internal SQL tokeniser routines.
550
551 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
552 being raised for valid set statements processed by a data formatter.
553
554 8. New published property for TIBDatabase and TIBXServicesConnection. This is
555 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
556 the path of the Firebird Library used by the database/services connection.
557
558 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
559 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
560 services connection.
561
562 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
563 or param name is not a valid SQL identifier.
564
565 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
566 view of whether the text box should be editable when no DataSource is specified.
567 TIBLookupComboEditBox has been updated to workaround this problem. As long as
568 ReadOnly is false, the text box is editable when no DataSource is specified.
569
570 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
571 the FBLIB environment variable. If you do not want to permit this then you
572 must modify the Register procedure in the design/IBDBReg.pas unit to remove
573 this setting.
574
575 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
576
577 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
578 Utf8EscapeControlChars
579
580 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
581
582 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
583 all previous copies of the IBX source code tree before installing this release.
584
585 The IBX packages used by most users have not changed, with one exception. The
586 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
587 to use the IBServices unit in your applications, please add the iblegacyServices
588 to the list of dependencies. To do this, open the Project Inspector and select
589 Add->New Requirement and select "ibLegacyServices" from the list of available
590 packages.
591
592 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
593 the IBServices unit providing what is intended to be a clearer and easier to
594 use set of IB Services components. See Chapter 10 of the IBX User Guide for
595 more information and the guide to "Firebird Service Management Using IBX".
596 As indicated above, the legacy services components are still available and
597 provided in a separate package. There is no need to update working applications
598 using the older versions except for an additional package dependency.
599
600 2. The IBX packages and source code tree have been re-organised in an attempt to
601 finally get rid of the "duplicate ppu" warnings. This re-organisation should
602 not affect existing users. Section 2.3 of the IBX User Guide describes the
603 new set of IBX packages.
604
605 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
606 updated to use the new Services API components.
607
608 4. The iblocal package has been updated to use the new Services API components.
609
610 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
611 TIBXSecurityService. It had been wrongly classified in the previous version
612 as a per database configuration item. It is global to a server and hence
613 correctly positioned as part of the Security Package. In the DBAdmin example,
614 the setting has moved to the mappings page.
615
616 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
617 are ignored.
618
619 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
620 closed before the database is dropped. Before and After Disconnect event handlers
621 are also fired.
622
623 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
624 is started and not just the first time.
625
626 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
627 depenendency with comp type.
628
629 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
630
631 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
632 then this is recognised and not ignored.
633
634 12. TIBDataSet, TIBQuery, TIBTable: additions:
635 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
636 function GetPerfStatistics(var stats: TPerfCounters): boolean;
637 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
638
639 GetRowsAffected returns the affected row counts from the last insert/update/delete
640 if EnableStatistics = true then GetPerfStatistics returns the current stats
641 counters for the select query. Note: stats accumulate after each fetch from
642 the database. To get total query cost after open, call the "Last" method
643 and then GetPerfStatistics.
644
645 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
646
647 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
648 in parenthesises.
649
650 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
651 SQL identifiers are always delimited by double quotes. If false, then they are
652 only delimited if the identifier is a reserved word, contains lower case or special
653 characters. Set this property to true to retain previous behaviour.
654
655 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
656 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
657
658 16. TIBDataSet, TIBQuery, TIBTable: addition:
659 property MasterDetailDelay: integer {defaults to zero}
660
661 When non-zero and the dataset is a detail table referencing a master table
662 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
663 then a synchronisation delay is added (in milliseconds) between the master
664 row changing and the detail dataset being re-opened. If the master dataset
665 is scrolled before the delay expires then the delay is reset. This can be used
666 to avoid performance overheads when scrolling through a large master dataset.
667
668 Note: uses fptimer and hence requires a thread manager. Under Linux the
669 chreads unit must be included in your project. TTimer is not used in order
670 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
671
672 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
673 with Extract Option eoDatabase.
674
675 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
676 When a deLayoutChanged event is reported on the ListSource dataset, the
677 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
678 relationship with the control's datasource (master).
679
680 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
681
682 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
683 stubs. Pedantic fix really, as procedures output in dependency order anyway.
684
685 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
686 DDL (Firebird 3 and later only).
687
688 22. TIBLookupComboBox Autocomplete Fixes:
689 i. Only appended text is now selected after autocomplete.
690 ii. Uppercase keys no longer ignored for autocomplete.
691 iii. Retain Prefix case is now honoured correctly.
692 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
693 before autocomplete performed. i.e. behaviour now the same as when
694 no DataSource assigned.
695
696 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
697 between SQL statements.
698
699 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
700 ObjectNames are converted to upper case before matching against metadata object
701 names, unless the objectname is delimited by double quotes, in which case, the
702 double quotes are removed and the remaining string is used (unmodified) to match
703 against the metadata object name.
704
705 If true then the ObjectName is used as is without modification and matched
706 against the metadata object name. No attempt is made to remove double quotes.
707
708 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
709 with eoTrigger, these extract types can be used to select only Database Triggers,
710 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
711
712 26. TIBXScript: If an exception occurs during the processing of a statement, the
713 statement separate character is now reset to the default (';').
714
715 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
716
717 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
718 a commit or reconnect statement and instead activated only when next SQL statement
719 is executed.
720
721 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
722
723 30. TIBXScript: case insensitive regex now used when matching statements instead of
724 converting statement to upper case.
725
726 31. TIBExtract: metadata comments now supported. New published property
727 IncludeMetaDataComments (default true). If true then metadata comments included
728 in extracted DDL. New Extract Object member eoComments. This may be used with
729 ExtractObject method to list all metadata comments.
730
731 32. TIBExtract: ListObjectNames method added.
732
733 33. Updated Database component editor to support additional connection string
734 types.
735
736 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
737
738 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
739 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
740 RELEASE.
741
742 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
743
744 1. IBExtract: Identity columns - add additional check for null column for generator name.
745
746 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
747 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
748 information). However, this is also a very useful mechanism for returning updated computed by
749 column values. Values returned as a result of executing an Insert or Update statement
750 replace existing values in the current row for each corresponding column.
751
752 Previously, if a dataset's select query included read only (computed by) fields then
753 an automatic row refresh was performed after an insert or update query had been processed,
754 irrespective of the setting of the "ForcedUpdates" property. This has changed such
755 that an automatic refresh is no longer performed if an insert or update query contains
756 a returning clause that updates one or more fields on the current row. A full row
757 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
758 field values and the select query contains read only fields. Use of Insert/update
759 returning should be significantly more efficient than executing a refresh query.
760
761 This behaviour change is intended to be backwards compatible and there should be no need to change
762 existing programs, other than to improve performance by using the new capability.
763
764 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
765 they are called when the dataset row is being deleted, there is no value in
766 updating the current record from the query result. Instead, a new event handler
767 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
768 an OnDeleteReturning event handler is provided then it is called with the IResults returned
769 by the query. The event handler can then interrogate the query results and
770 perform whatever action is necessary. For example to confirm, to the user,
771 the deletion of a row with the returned values.
772
773 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
774 any Computed By or Identity Columns. The IBTables example has been updated to
775 illustrate the computation of the employee Full Name on update.
776
777 5. TIBTable: The GeneratorField property is now published.
778
779 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
780 When InsertSQL is generated, the Identity columns are not included in the list of values to
781 be inserted. A RETURNING clause is added to the insert statement to return the value of
782 each Identity column after the insert is executed.
783
784 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
785 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
786 Insert..Returning clause.
787
788 8. TIBGenerator: small performance improvement by not preparing query each time
789 a new value is generated.
790
791 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
792
793 10. Property editors will now sync table name to a System Table when "Include System
794 Tables" is selected and the query is for a System Table.
795
796 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
797 values are no longer converted to milliseconds from TDateTime and then back again
798 to TDateTime (the conversion to milliseconds is the default TDataset approach).
799
800 12. Property Editors handling of Stored Procedures.
801 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
802 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
803 query).
804 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
805
806 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
807 can be used to select a package. If non-empty, the stored procedure name is
808 expected to be a stored procedure defined in the specified package and the
809 generated SQL will be as required for a stored procedure located in a package.
810
811 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
812 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
813 which a stored procedure can be selected. With no package name selected, non-package
814 stored procedures are listed.
815
816 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
817 for password on reconnect.
818
819 16. TIBDatabase: use IAttachment for connection default character set id, code page
820 and character set name.
821
822 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
823 DB info lookups"
824
825 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
826
827 19. Add a property Editor for TIBUpdate.RefreshSQL.
828
829 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
830 parameters. This stops an exception being raised when the field cannot be
831 located in the record buffer.
832
833 21. Property Editors now automatically include System Tables when opened and when the query table
834 is a System Table.
835
836 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
837 This avoids errors due to a stale SQRB or SRB being used for the next query.
838
839 23. IBServices: Service attach parameters now include "expected_db". This is used to
840 add the SPB item isc_spb_expected_db. This names a database using
841 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
842 database. examples/services re-written to illustrate use of "expected_db".
843
844 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
845 This avoids truncated backups when the server returns a timeout (busy) response.
846
847 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
848
849 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
850 databasenames. These are respectively expanded to the local system's temp directory
851 (including trailing delimiter) or to a prescribed data directory (including
852 trailing delimiter). Under Unix systems the data directory is a hidden directory
853 in the user's home directory. The hidden directory name is either the string returned
854 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
855 Under Windows, the directory is the same as the Data Directory as decribed
856 above but instead prefixed by the User's application data path. These may be
857 used to improve application portability for Personal Databases.
858
859 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
860 this has not worked for a long time and is not useful either. FieldDefs should be
861 managed using the Fields Editor as with any other dataset. To access the fields
862 editor for a TIBTable component, double click on the component. The fields editor
863 is then displayed.
864
865 28. TIBDatabaseInfo: new properties/function
866 * DateDBCreated (returns date/time database created)
867 * TransactionCount (returns no. of active transactions)
868 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
869 * PagesFree (Firebird 3 or later)
870 * PagesUsed (Firebird 3 or later)
871 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
872 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
873
874 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
875
876 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
877
878 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
879 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
880
881 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
882 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
883 firing during backup and restore.
884
885 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
886 for verbose output using the new property "StatisticsRequested".
887 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
888
889 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
890
891 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
892 palette. This uses the online validation feature added in Firebird 2.5. The
893 services's properties enable inclusion/exclusion of tables and indexes using
894 regular expressions. See.
895 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
896
897 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
898 option on a database.
899
900 37. TIBCustomService: Assign method implemented to allow copying of service login
901 context between service API components. "Detach" method now only detaches
902 service when last reference to the service interface detaches. Tidy up of
903 code for SetActive and Attach methods including password hiding.
904
905 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
906 and used to determine the auth method and protocol used for the connection.
907
908 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
909 a Create Database Statement generated by IBX.
910
911 40. All IBServices now have an additional published property "PortNo". This may
912 be set to a non-standard port number when necessary. If zero then the default
913 port number is used.
914
915 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
916 and not just the mouse.
917
918 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
919
920 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
921 image index and selected image index for each node to be set from a database field.
922
923 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
924 then database schema includes grants to all users. If not present then the
925 only user grants included are those to User PUBLIC.

927 45. TIBTreeView: performance improvement. When expanding include both expanded node
928 and child nodes in dataset.
929
930
931 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
932
933 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
934 changes.
935
936 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
937 Bug could result in truncated multi-byte character set values.
938
939 3. Changes consequential on moving fbintf character set utility functions from
940 IFirebirdAPI to IAttachment.
941
942 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
943
944 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
945 results in autocomplete ignoring prefix text.
946
947 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
948 entering a new name into the text box.
949
950 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
951 Firebird rather than recomputing it.
952
953 8. Property Editor positioning tidy up: All IBX Property editors should now be
954 screen centre. Previously some were "poDesigned" which may be inappropriate
955 for multi monitor desktops.
956
957 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
958
959 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
960 a transaction and always reset the object.
961
962 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
963
964 13. TIBXScript: Allow for override of database filename in Create Database statements.
965
966 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
967 to a gbak format archive.
968
969 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
970
971 16. IBLocaldb: Drop database if error creating an empty database.
972
973 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
974 unless selected node not in current dataset.
975
976 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
977 to TIBCustomService, and IBlocalDB code tidy up.
978
979 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
980 behaviour due to uninitialised variable.
981
982 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
983 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
984
985 21. IBSQL: When Database changed ensure that all resources are freed.
986
987 22. IBCustomDataset: When database changed ensure that queries an unprepared.
988
989 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
990 * Line Wrap on SQL Token boundaries (on user command)
991 * auto-complete table names in drop down list of table names
992 * Double click on tablename or field name adds to SQL text
993
994 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
995
996 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
997 TVariantArray. Seems to avoid memory corruption in Windows (probably a
998 workaround for a problem in fpc 3.0.4 win64).
999
1000 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
1001
1002 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
1003
1004 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
1005
1006 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
1007 include remote system name.
1008
1009 2. TIBExtract: No longer include comment header and COMMIT statement for empty
1010 tables when data included in output.
1011
1012 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
1013 and timing information to be written to stdout. This may be used to locate
1014 performance bottlenecks.
1015
1016 4. SQLParser: only call "OnChanging" event handler when value is different.
1017
1018 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
1019
1020 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
1021 that BindFields is called when the query is next activated. Avoids FieldName
1022 not found error.
1023
1024 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
1025 purpose and allows the programmer to define any action they want for Update, Insert
1026 or Delete. This may be complex SQL (similar to a Trigger), application specific
1027 filtering of updates, or use of statements such as Grant or Revoke instead of
1028 normal DML. See User Manual for more information.
1029
1030 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
1031
1032 1. TIBEvents: Fix uninitialised variable that could result in lost events.
1033
1034 2. TIBExtract: Added support for FB3 "USAGE" privilege.
1035
1036 3. TIBExtract: data formatted as Charset set "octets" is now output using
1037 hexadecimal notation.
1038
1039 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
1040 using a simple XML format.
1041
1042 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
1043 grants to these objects.
1044
1045 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
1046 dependency problems restoring complex databases.
1047
1048 7. TIBXScript: This component has been restructured to allow for the processing of
1049 embedded XML in INSERT statements and to support interactive sources in addition
1050 to non-interactive data sources such as files.
1051
1052 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
1053
1054 9. TIBXScript: ISQL compatiable Set statements are now supported:
1055 SET SQL DIALECT
1056 SET TERM
1057 SET AUTODDL
1058 SET BAIL
1059 SET ECHO
1060 SET COUNT
1061 SET STATS
1062 SET NAMES <character set>
1063
1064 10. IBVersion unit added to hold current IBX Version Number information.
1065
1066 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
1067 and domain definitions.
1068
1069 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
1070 fully supported.
1071
1072 13. TIBExtract: when a database dump includes data, the generator values are now also set.
1073
1074 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
1075
1076 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
1077
1078 See also doc/IBX4LazarusGuide.pdf for important information on
1079 upgrading to IBX2.
1080
1081 1. Size property of TIBStringField is now the width in characters of the field
1082 and not the byte length. This applies only to multi-byte character sets such
1083 as UTF8. The original approach aligned with TStringField. However, the TStringField
1084 code is not recognised as a bug and hence this change to align the behaviour.
1085 The TStringField change is expected in fpc 3.2.0.
1086
1087 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
1088 true (default) then Size property value saved in the lfm is ignored. Size is
1089 always set from the dynamic information read from the database. It is unclear
1090 why anyone would want to override this and set Size to false.
1091
1092 3. ibxscript: should now handle correctly a Case..End statement within a procedure
1093 block.
1094
1095 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
1096 exist when an attempt is made to connect to it (run time only) then an attempt
1097 is made to create the database.
1098
1099 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
1100 has been successfully created as a result of a call to CreateDatabase or when
1101 creating a database after it was found not to exist.
1102
1103 6. DBControlGrid: a race condition could result in the wrong row image being
1104 written to the cache. This has been avoided by a trip round the message
1105 loop before rendering the row image.
1106
1107 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
1108 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
1109 known to risk corrupt rendering of row images when the control is first
1110 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
1111 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
1112
1113 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
1114 a TDateEdit control located on an editor panel.
1115
1116 9. TIBExtract: brought up-to-date plus many bug fixes.
1117
1118 10. DBControlGrid: Removed memory leak when updating rows.
1119
1120 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
1121
1122 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
1123
1124 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
1125 when target codepage is CP_NONE. This is a workaround for
1126 http://bugs.freepascal.org/view.php?id=30622.
1127
1128 2. DBLog option removed from TIBStatisticalService - not supported by server
1129 since Firebird 1.5.
1130
1131 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1132 similar.
1133
1134 4. IBCodePage: updated mapping between codepages and character id.
1135
1136 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1137 Firebird. Character sets with a char width of two are not UTF16.
1138
1139 6. Strings received from the database are now always transliterated into UTF8
1140 regardless of the database character set or connection character set. This
1141 is for compatibility with the LCL.
1142
1143 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
1144
1145 1. IBBlob: Defer reading of blob until read method called. This avoids having to
1146 read in an entire blob just to get the size of the blob. General performance
1147 improvement when opening datasets containing blobs.
1148
1149 2. Clearing a Blob now sets the corresponding field's modified flag.
1150
1151 3. IBLookupCombo: When not performing auto-complete, original query sort order
1152 is now used.
1153
1154 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1155 determined.
1156
1157 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1158
1159 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1160 lazarus 1.6.0
1161
1162 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
1163 compilation error.
1164
1165 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
1166
1167 1. No character set specified for connection: when a text blob is retrieved, the
1168 character set is determined by looking up the native character set using then
1169 Firebird API. Otherwise a text mode blob is assumed to have the same character
1170 set as the connection.
1171
1172 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1173 for Login Dialog returing a change to the database path.
1174
1175 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1176 to be changed from that given in the TIBDatabase/TIBServer component and for the
1177 entered value to be saved on a project specific basis (design time only).
1178
1179 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1180 column fieldname. If they are the same then it is acts as a look up for the KeyValue
1181 Otherwise, it sets the column text to the selected ListField Value.
1182
1183 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1184 column width.
1185
1186 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1187 and a case insensitive search is requested.
1188
1189 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1190 or column ListSource.
1191
1192 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1193 unprepare) when closing and the text has not changed.
1194
1195 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1196 Less likely to cause a cursor re-use error on Windows.
1197
1198 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1199 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1200
1201 11. TIBTreeView: Guard against nil destination on record changed
1202
1203 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1204 string type with the code page set to reflect the returned field encoding after
1205 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
1206 earlier versions.
1207
1208 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1209 will now result in transliteration to the code page specified for the Firebird driver
1210 if the assigned string has a different code page. FPC 3.0.0 onwards only.
1211
1212 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1213 is ignored and the lc_ctype value, when the database is opened, is set to align with
1214 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1215 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1216 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1217 the GETACP is used to determine the Windows code page.
1218
1219 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1220 name used as the lc_ctype when the database was opened. Only valid while the
1221 Database is connected.
1222
1223 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1224 id that corresponds to the DefaultCharSetName.
1225
1226 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1227
1228 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1229 path is given and database attach fails due to access permission issues on the
1230 temp directory or security database, then the attach is retried with "localhost:"
1231 prefixing the databasename. This should avoid problems when the database has to
1232 be accessed by a local (e.g. classic) server and libfbembed is used.
1233
1234 2. Windows: revised search order for Firebird DLL:
1235 i. The Firebird Embedded Server in the application Directory.
1236 ii. If the FIREBIRD environment variable is set then the directory this
1237 points to is searched for the FB Client DLL and then then underlying
1238 "bin" directory.
1239 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1240 is used to locate the Firebird installation directory and the underlying
1241 "bin" directory is searched for the FB Client DLL.
1242 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1243 are searched for the FB Client DLL.
1244 v. The PATH Environment variable is used to search for the FB Client DLL.
1245 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1246
1247 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1248 See doc/readme.scriptengine and example applications.
1249
1250 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1251 simplify the use of the embedded firebird server on both Linux and Windows platforms.
1252 See dpc/readme.localdatabase and example applications.
1253
1254 5. IBDynamicGrid: Reordering on column header click should now also work for
1255 dynamic columns.
1256
1257 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1258 between incrementing/decrementing the lock count and signalling the event.
1259
1260 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1261
1262 1.3.2 was never formally released and only made available as beta copies.
1263
1264 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1265
1266 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1267
1268 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1269
1270 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1271 i.e. when it is a calculated field
1272
1273 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1274 This problem was due to a race condition between recalculating row heights and
1275 determining which row was selected by the mouse click. The row height calculation
1276 is now deferred by an extra trip round the message loop allowing the row to
1277 be always calculated on the current grid layout rather than risking it being
1278 calculated on the grid layout after the expanded row has been shrunk.
1279
1280 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1281 Windows.
1282
1283 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1284 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1285 to be determined at runtime. See doc/readme.charactersets.html.
1286
1287 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1288 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1289
1290 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1291 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1292 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1293
1294 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1295 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1296 implies no truncation.
1297
1298 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1299
1300 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1301 (avoids "Not in Edit Mode" error).
1302
1303 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1304
1305 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1306 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1307
1308 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1309
1310 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1311
1312 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1313
1314 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1315
1316 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1317
1318 1. OnCloseUp Event Handler added to TDBLookupProperties
1319
1320 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1321 problem with row size when exception is called.
1322
1323 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1324
1325 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1326 in a TCustomComboBox and ignores return key if in a TCustomMemo
1327
1328 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1329 keyed in i.e. when autocomplete not performed
1330
1331 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1332 console mode applications with all LCL required functions (builtin dialogs and
1333 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1334 not included in your project, IBX should compile and link with a console mode program.
1335 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1336 console mode application or the IDE will automatically assume that your
1337 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1338
1339 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1340 to use the built in dialogs and cursor management. IBDialogs is
1341 included by default if "ibexpress" is in your project source's "uses" clause.
1342 This should be the case for all projects created through the IDE. This is why
1343 you do not want to add the ibexpress package to console mode applications. The
1344 ibexpressconsolemode package has been created to allow console mode programs
1345 to avoid adding LCL dependencies when using IBX, while still having the
1346 unit search paths set up correctly.
1347
1348 Existing users should check to ensure that the "ibexpress" unit is included in
1349 each project's source file (*.lpr).
1350
1351 You may find that in order for the IDE to recognise that ibexpressconsolemode
1352 exists, you have to first open the package in the IDE and then close it. This
1353 adds it to the most recently accessed packages list. To make it permanently
1354 available, add the package name to lazarus' staticpackages.inc file.
1355
1356 Thanks to Julio Jiménez for suggesting support of console mode.
1357
1358 7. SQL Parser can now accept quoted strings that include new lines
1359
1360 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1361 of text on start of edit. This is particularly useful when tabbing to a
1362 column and then inserting text.
1363
1364 9. New Examples provided for IB Services and ISQLMonitor.
1365
1366 10. Fix error when writing to blob streams that recorded only the last buffer
1367 write in the blob stream. In most cases, this did not cause a problem as the
1368 IB Blob Stream is written in a single write. However, with the TDBImage, write
1369 of a graphic type prefix was lost which caused a problem when the image could
1370 not be automatically recognised.
1371
1372 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1373 already open" errors due to random numbers used for the cursor name being identical.
1374
1375 12. IBTable: corrected error that could result in an "Index out of bounds" error
1376 when opening the table and the Primary Key is the last or only column in the
1377 table. Thanks to Rick Hoover for the fix.
1378
1379 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1380 of "UTF-8", and update list of available database character sets. Existing
1381 users should check the current lc_ctype setting in their applications.
1382
1383 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1384
1385 1. Firebird Services: avoid List Index error when opening a service with an
1386 empty Params property.
1387
1388 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1389 Link now set up in Loaded method - avoids occasional failure to apply
1390 SQL markup on initial open.
1391
1392 3. "Employees" example performance improvements when scrolling.
1393
1394 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1395 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1396 random image cached).
1397
1398 5. DBControlGrid: Should now react to changes in panel height at run time.
1399
1400 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1401 even when further rows exist.
1402
1403 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1404 always be derived from panel height and setting this property can cause confusion.
1405 Note for existing projects: to avoid a missing property error at run time,
1406 each form using the DBControlGrid must be opened, updated and saved in the IDE
1407 in order to remove the property value from the lfm.
1408
1409
1410 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1411
1412 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1413 call Prepare before setting parameter values.
1414
1415 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1416
1417 3. Code tidyup and more robust handling of dsql information result vector.
1418
1419 4. Support for centralised handling of transaction status changes. TIBTransaction
1420 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1421 and "AfterExecQuery". The first three are called after the same event is called
1422 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1423 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1424 enable monitoring of transaction status changes for a given transaction to be
1425 handled in a single place. For example, when a change to the dataset occurs
1426 an indicator can be set that shows the user that in order to save changes,
1427 the transaction should be committed. Rather than doing this per dataset, this
1428 can now be done per transaction.
1429
1430 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1431 the dataset is scrolled. However, any changes to the current row are, by default,
1432 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1433 have a new property "DataSetCloseAction" that adds automatic posting of changes
1434 on dataset close. If this property is set to dcDiscardChanges (default) then the
1435 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1436 then IBX will attempt to post any unsaved changes before the dataset is closed
1437 (and after the BeforeClose event handler is called). The exception is when the
1438 dataset is being closed as a result of a transaction rollback. In this case,
1439 no action is taken and any unsaved changes are discarded. This avoids both
1440 unnecessary overhead and the risk that a validation error may occur in the Post
1441 raising an exception and thereby preventing a rollback.
1442
1443 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1444 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1445 width. Display Widths are now corrected by dividing by the max byte width per character.
1446 For UTF8 character sets, the byte width is four and hence the Display Width will be
1447 the byte width divided by 4. The byte width of each character set is determined
1448 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1449 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1450
1451 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1452
1453 8. IBLookupComboEditBox: List should now always be restored to full list when the
1454 control loses focus. Default Key press default interval reduced to 200ms.
1455
1456 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1457 when dataset rows are less than visible rows.
1458
1459 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1460 does not exist or DataSet is empty. More responsive on dataset open. New event
1461 OnRestorePosition. Column sort disabled if no header row.
1462
1463 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1464 while dataset state is dsInsert. Avoids posting errors.
1465
1466 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1467 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1468
1469 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1470
1471 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1472 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1473 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1474 always "posts" the current record regardless or whether or not it may be more appropriate
1475 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1476 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1477 as the first action of the "Post" method and allows the handler to convert the Post
1478 into a Cancel if that is the appropriate action on moving to a different row. This is
1479 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1480 raised here, but it may still be more appropriate to validate a post and signal
1481 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1482
1483 15. On Unix derived systems, the Firebird library name can now be given as a colon
1484 separated list. Each library name on the list is tried in turn, in left to right
1485 order with the first found being used as the firebird library. By default, on Linux,
1486 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1487 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1488
1489 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1490 then it will still attempt to access the database via the Firebird Server and will
1491 require a username and password. If only the pathname is given, then the username
1492 and password should be omitted and the unix file permissions are used to grant
1493 access.
1494
1495 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1496
1497 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1498 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1499 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1500 corresponds to a row of the linked DataSource. Any data aware control on the
1501 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1502
1503 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1504 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1505 takes place during database access. This may be useful when there are performance issues with
1506 the change of cursor. Setting the property to false suppresses the change of cursor.
1507
1508 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1509 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1510 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1511 making all changes permanent immediately rather than when the transaction is explicitly
1512 committed.
1513
1514 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1515 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1516
1517 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1518
1519 Development version only.
1520
1521 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1522
1523 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1524 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1525 "Where" and "Having" clauses to implement user specified filters of arbitrary
1526 complexity.
1527
1528 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1529 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1530 These are:
1531
1532 - TIBLookupComboEditBox
1533 - TIBDynamicGrid
1534 - TIBTreeview
1535
1536 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1537 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1538 to revise the available list and restrict it to items that are prefixed by the
1539 typed text (either case sensitive or case insensitive). Autoinsert allows a
1540 newly typed entry to be added to the list dataset and included in the available
1541 list items.
1542
1543 TIBDynamicGrid is a TDBGrid descendent that provides for:
1544 - automatic resizing of selected columns to fill the available row length
1545 - automatic positioning and sizing of a "totals" control, typically at the
1546 column footer, on a per column basis.
1547 - DataSet resorting on header row click, sorting the dataset by the selected column.
1548 A second click on the same header cell reversed the sort order.
1549 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1550 is automatically expanded and a panel superimposed on it. The panel can have any
1551 number of child controls, typically data aware controls with the same datasource
1552 as the grid allowing for editing of additional fields and more complex editors.
1553 - Reselection of the same row following resorting.
1554 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1555 Its properties are specified on a per column basis and allows for one or more
1556 columns to have their values selected from a list provided by a dataset.
1557 Autocomplete and autoinsert are also available. The existing picklist editor
1558 is unaffected by the extension.
1559
1560 TIBTreeView is a data aware TCustomTreeView.
1561
1562 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1563 zero scale will no longer return an error. An Int64 will be returned instead.
1564
1565 4. TIBTransaction now has events for Before and After Transaction End and a new function
1566 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1567
1568 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1569 repeated multiple times.
1570
1571 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1572 check used to get in the way of using Stored Procedures, and "Update or Insert"
1573 statements.
1574
1575 7. Insert, Modify and Delete property Editors now support Query Generation from
1576 Stored Procedures.
1577
1578 8. Three new examples illustrate the use of the new IB Controls
1579
1580
1581 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1582
1583 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1584 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1585 Gabor Boros for reporting this problem and for testing the improvements).
1586
1587 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1588 See readme.field+param.names in the doc folder.
1589
1590 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1591 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1592
1593 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1594
1595 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1596 actions.
1597
1598 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1599 thanks to Yuriy Kopnin for pointing this out).
1600
1601 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1602
1603 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1604 for both fields and parameter setting.
1605
1606 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1607 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1608
1609 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1610 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1611
1612 11. TIBTable now has a property editor for "MasterFields"
1613
1614 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1615 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1616
1617 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1618 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1619

1621 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1622
1623 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1624
1625 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1626
1627 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1628 it is null. This allows for alternative user defined setting of the generator
1629
1630 Many thanks to Julio Jiménez for this fix
1631
1632 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1633 and suggests that the user may have forgotten to install it.
1634
1635 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1636
1637 1. Conditional compilation used to limit registration of TIntegerField to
1638 Lazarus versions less than 1.1
1639
1640 2. When a database connection is created, character set is now by default set
1641 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1642 1250 to 1254.
1643
1644
1645 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1646
1647 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1648
1649
1650 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1651
1652 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1653 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1654
1655 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1656 package is changed to do this (which it should do).
1657
1658 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1659
1660 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1661
1662 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1663
1664 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1665
1666 4. Property editors should now correctly resize.
1667
1668 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1669 (restored original functionality)
1670
1671 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1672 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
