1 IBX Change Log version (2.6-4 Build 14165) Sat, 30 Dec 2023 16:04:23 +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 IBX Change Log version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100
29
30 1. Update to calls to EInterbaseError to add default code page. Consequential
31 on change to fbintf.
32
33 2. Update some examples to replace test for null date with the NullDate constant
34 instead of zero. This is because Laz 3.0 changes the value of NullDate.
35
36 IBX Change Log version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100
37
38 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
39 with later versions of fpc - later than 3.2.2.
40
41 2. IBUpdateSQL. update internal queries if parent dataset database changed.
42
43 3. IBUpdateSQL: Do not prepare an empty internal query.
44
45 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
46
47 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
48
49 IBX Change Log version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
50
51 1. Maintenance update of 2.6.0. This version is still at beta.
52
53 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
54 See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
55
56 3. ibxscript: When parsing a store procedure or function with a variable name
57 enclosed in doublequotes, the double quotes are no longer removed.
58
59 IBX Change Log version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
60
61 NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
62 AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
63 BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
64 ISSUES TO support@mwasoftware.co.uk
65
66 1. Complete rewrite of internal buffer management in order to improve performance
67 and maintainability. Highlights:
68
69 * Extending the size of the buffer pool no longer has to copy the entire record
70 cache. Instead, a new extent is simply added to the buffer pool.
71 * A memory to memory copy of each display buffer now is avoided when scolling the
72 dataset.
73 * A separate set of buffers is now used for calculated fields. This avoids
74 having to keep copies of calculated field values in the buffer cache.
75 * Compact bitmaps are used to record null status and need to refresh in each
76 buffer.
77 * Display buffer type changed from PChar to TRecordBuffer in line with change of
78 buffer type in FCL-DB.
79
80 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
81 to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
82
83 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
84 If either or both of these flags are set at design time (using the fields editor)
85 then this forces a row refresh on respectively insert or update, or both, when the
86 corresponding field is not present in an SQL RETURNING clause.
87
88 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
89 maintainability and readability and to add identification of primary key fields.
90
91 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
92 as a refresh of the current row. However, this is different behaviour to that described
93 in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
94 the dataset from the underlying database, and attempts to reposition the cursor on
95 the same record as it was". IBX now complies with the FPC definition of Refresh.
96
97 6. A progammatic Row Refresh should no longer be required.
98 Use Insert/Update... returning to refresh any fields that may change following an
99 insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
100 on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
101 for the field at Design Time to force a row refresh if not in the returning clause.
102
103 7. It should now be possible to insert a row into an empty unidirectional dataset.
104
105 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
106 This gives the number of buffers in the initial block for the buffer pool in
107 bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
108 in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
109 for small datasets.
110
111 IBX Change Log version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
112
113 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
114
115 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
116
117 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
118
119 IBX Change Log version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
120
121 1. TIBTransaction: new properties
122 property TransactionID: integer read GetTransactionID;
123 property IsReadOnly: boolean read GetIsReadOnly;
124 {published}
125 property TransactionName: string read FTransactionName write SetTransactionName;
126
127 2. IBCustomDataset: per row blob and array buffer cached clear before processing
128 Insert or Update...Returning. This allows blobs and arrays to be returned
129 by the statement.
130
131 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
132
133 4. TransactionName initialised to a newly generated GUID if empty.
134
135 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
136 for the fbintf package's journaling capability. TIBJournal is used to set the
137 file path and filename for the journal file and to Enabled (start journaling) and
138 disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
139 more information, and comments in IBJournal.pas.
140
141 6. TIBDatabase.InternalTransaction is now a read only transaction.
142
143 7. Bug fix: blob id no longer set to null on update when blob has not been
144 retrieved.
145
146 8. Row auto refreshed on update/insert if blob or array field updated and field
147 not in a returning clause.
148
149 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
150 buffer overhead and avoids problem when refresh query has a different column
151 count to select query i.e. incorrectly changing number of columns.
152
153 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
154
155 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
156 string. Note that the Version property returns an InterBase compatible version string.
157
158 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
159
160 IBX Change Log version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
161
162 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
163 This is for compatibility with Firebird 5 where Update...Returning can return
164 a cursor.
165
166 IBX Change Log version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
167
168 1. Add try-..except check when initially loading library in IDE. This should
169 ensure that IDE continues to load even when a failure occurs in IBX load
170 library.
171
172 2. IBXScript: now recognises a CASE...END block within a stored procedure and
173 hence will correctly detect end of the outer containing block when the block
174 contains a SELECT ... CASE ... END construct.
175
176 3. IBExtract: some further tidying up to remove extraneous white space.
177
178 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
179 errors when extra elements are added to DB.TFieldType.
180
181 5. IBUpdate: updated to reflect changes to ISQLParam.
182
183 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
184
185 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
186
187 8. IBSQL: Support for scrollable cursors added (note: local databases only)
188
189 IBX Change Log version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
190
191 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
192 exception of those defined to be one byte wide e.g. DBImplementationNo.
193
194 2. TIBSQL: Batch Update/Insert support added.
195
196 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
197 is no longer automatically converted to upper case when it is syntactically a
198 SQL Identifier. This is to support the use of stored procedures defined e.g.
199 as CREATE PROCEDURE "iCASE".
200
201 There could be a backwards compatibility issue when the StoredProcName was entered
202 manually at design time. That is not selected from the drop down list. If the
203 StoredProcName is entered in mixed case and the procedure was declared e.g. as
204 CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
205 ensure that the value of the StoredProcName is all upper case, unless it was
206 declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
207 quotes).
208
209 Note that when a stored procedure name was declared delimited in double quotes,
210 as in the first example above, the value of the StoredProcName property must not
211 include the delimiters (double quotes).
212
213 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
214 upgrade.conf was not found. This replaces silently ignoring the problem.
215
216 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
217 'Version.%.3d' and is used to generate the section header names (for a given
218 version no.) in the upgrade.conf file.
219
220 IBX Change Log version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
221
222 1. -c command line option added to fbsql example program. Used to set connection
223 character set.
224
225 IBX Change Log version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
226
227 1. Firebird 4 support added.
228
229 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
230 extended precision NUMERIC fields are supported.
231
232 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
233
234 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
235 and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
236
237 5. IBExtract now supports FB4 enhancements:
238 - new data types as above
239 - Identity column extensions
240 - Default user role
241 - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
242 - Internal Functions
243
244 6. IBExtract: new event: OnExtractLines.
245
246 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
247
248 8. IBXServices: Server version no. parsing now allows any letter before major version number
249 and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
250
251 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
252 format for rendering a time zone.
253
254 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
255 to convert TIME WITH TIME ZONE data type values to and from GMT.
256
257 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
258 IIBGUIInterface and IIBTimerInf respectively.
259
260 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
261 now accessible as properties of TIBDatabase and TIBTransaction respectively.
262
263 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
264 truncated to its fixed character width rather than being right padded with
265 white space to the maximum data size.
266
267 14. TIBTable.Empty table. In additional to deleting all records in the underlying
268 table, the internal buffers are now also flushed ensuring that the TIBTable is
269 also empty.
270
271 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
272
273 16. TIBXControlService descendents: DatabaseName may now be set using a database
274 connect string. The database name is extracted from the connect string.
275
276 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
277
278 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
279
280 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
281 not being present as required.
282
283 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
284 version that can be customised to work with other database drivers.
285
286 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
287 unnecessary CR at end of line on Unix platforms.
288
289 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
290 seconds in order to reduce risk of message loss.
291
292 23. ISQLMonitor: read and write count statistics now available via:
293 property TIBSQLMonitor.ReadCount;
294 IIBSQLMonitorHook.GetWriteCount: integer;
295
296 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
297
298 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
299
300 1. TIBStringField: when a string value is read from a dataset buffer, if the
301 number of UTF8 characters exceeds the string size then string is truncated
302 to the maximum string size. This is usually a problem with fixed width columns
303 right padded with white space.
304
305 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
306 If SQLFiltered is set then when a dataset is opened, each line in the
307 SQLFilterParams property is assumed to be a SQL condition clause and
308 ANDed into the Where clause of the SQL Select statement provided as a
309 dataset property. Each such SQL condition thus acts as an additional filter
310 on the dataset.
311
312 3. The Filtered property inherited from TDataset is no longer used for SQL (server
313 side filters).
314
315 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
316 text matches complete entry.
317
318 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
319 dataset are active (avoids risk of access violation if master is inactive)
320
321 6. TIBEvents: Registered property can now be set at design time even if database not open
322
323 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
324 This should prevent "spillover" of events between sessions.
325
326 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
327 This should ensure that the internal buffer is set up correctly and avoids
328 a duplicate initial row.
329
330 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
331 That is, the DataSize should be the field size * character set width. The
332 value returned by DataSize is now the same as the Dataset buffer size reserved
333 for the field.
334
335 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
336
337 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
338 and vice-versa. This may result in an exception being raised (correctly) for
339 older programs when using dataset fields added to a form and the database has been
340 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
341 In such cases, the field needs to be deleted in the IDE fields editor and then
342 added back in.
343
344 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
345 false if query contains only white space and not just empty.
346
347 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
348 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
349 is cancelled.
350
351 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
352 called on a null field.
353
354 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
355 results in an empty dataTC86 Client side Filtered Dataset 1 X
356 set.
357
358 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
359 a cached update is applied and an exception is raised.
360
361 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
362
363 17. Console Mode Local Database support: backup/restore should now work correctly.
364
365 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
366 possible and an exception raised.
367
368 19. MinimumVersionNo added to Local Database Support. Database will not open if
369 below this version no. and upgrade not possible.
370
371 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
372
373 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
374 not SQL Identifiers are now supported.
375
376 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
377 passed to the Firebird engine for execution.
378
379 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
380 is made to scroll back.
381
382 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
383
384 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
385 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
386
387 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
388 validated. If no match is found in the list of field names and the database has
389 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
390 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
391
392 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
393 with fpc 3.2.
394
395 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
396
397
398 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
399 and is used to override the default settings in the client side "firebird.conf" This
400 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
401 Each line of the string list should be a setting in the same format as "firebird.conf".
402 For example "WireCompression = true" in order to request wire compression on the client side.
403
404 Note: explicit settings in the client side "firebird.conf" appear to take precedence
405 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
406 also require a compatible setting in the server side "firebird.conf". For example
407 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
408 compression to be used.
409
410 Whether or not WireCompression or WireCrypt are in use can be checked using the information
411 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
412 ibx/examples/dbinfo for examples of how to display this information.
413
414 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
415 is a "convenience" property. If set the "WireCompression=true" is added to the
416 ConfigOverrides. If unchecked then this setting is removed.
417
418 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
419 not "INT64".
420
421 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
422 These are:
423 property TimestampFormat: string;
424 property DateFormat: string;
425 property TimeFormat: string;
426
427 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
428 DATETIME and TIME. The format strings use the standard FPC date/time format
429 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
430
431 If any of the above properties are set to an empty string, then the locale default
432 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
433 locale default is extended by appending '.zzz' to include milliseconds.
434
435 TIBCSVDataOut by default sets these properties to the empty string, while the other
436 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
437
438 5. New published property for TIBCSVDataOut:
439 property QuoteStrings: boolean (default true)
440
441 If false then strings are unquoted, otherwise, the QuoteChar property value is
442 used to delimit each and every string in the output.
443
444 6. New published properties for TIBCSVDataOut:
445 property FieldSeparator: string;
446 property HeaderSeparator: string;
447
448 Respectively, these provide the separator character(s) used to separate fields
449 in data and header rows. Both default to ','.
450
451 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
452 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
453 property OnFormatTextString;
454
455 This event handler can be used to process text strings before they are included
456 in the output e.g. to replace unprintable characters with alternative strings.
457 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
458
459 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
460 Uses "FindParam" if in order to find out if a parameter with a given name exists
461 and without raising and exception if it does not.
462
463 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
464 consistency with SQL queries.
465
466 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
467 When true, SQL statement parameter names are parsed case sensitive. Note for
468 TIBDataSet only applies to Select query.
469
470 11. IBEvents: removing a TIBEvent component from a form should no longer result in
471 an IDE exception.
472
473 12. LocalDBSupport: initial database creation should now work correctly
474 when the schema source is an sql file.
475
476 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
477 when defined, this handler will be called by the internal TIBXScript during
478 initial database creation when the schema source is an sql file and may be used
479 to provide a visual indication of progress in console mode.
480
481 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
482 to true while a new local database is being created and its schema populated.
483 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
484 when the database is disconnected/connected during the create DB procedure.
485
486 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
487 are now always ignored and replaced by the user name and password provided as
488 the login parameters for the TIBDatabase referenced from the TIBXScript. The
489 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
490 completely ignored if this property is true.
491
492 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
493 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
494 ImageIndex and SelectImageIndex values on AddNode.
495
496 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
497 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
498 the same database connection.
499
500 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
501 if provided, this should be an conditional SQL expression suitable for
502 including in an SQL Select statement "where" clause. If non-empty and the
503 "Filtered" property is true then the SQL expression provided as the value of
504 the "Filter" property is "ANDed" with any existing condition statement
505 in the SQL statement's "Where" clause.
506
507 If the "Filter" property is set at run time, the "Filtered" property is true
508 and the dataset is already open, then the dataset is closed and re-opened automatically.
509
510 The "Filter" condition may include IBX style parameters. In which case, their
511 value must be set by the dataset's "OnBeforeOpen" event handler.
512
513 This is a public property for TIBDataSet and TIBQuery query and intended for
514 use at run time.
515
516 Note: The property is a published property of TIBTable. The TIBTable functionality
517 is unaffected by this change.
518
519 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
520
521 1. Remove need to check for IsMultiThread by providing access to GUI timers via
522 IBGUIInterface. Note: master/detail delay timer does not apply to console
523 mode apps.
524
525 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
526 statement. This avoids problems if "Execute Block" is used as the Query.
527
528 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
529 internal SQL tokeniser routines.
530
531 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
532 as a select statement, with or without CTEs.
533
534 5. IBSQLParser: parser now recognises the "ROWS" clause.
535
536 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
537 internal SQL tokeniser routines.
538
539 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
540 being raised for valid set statements processed by a data formatter.
541
542 8. New published property for TIBDatabase and TIBXServicesConnection. This is
543 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
544 the path of the Firebird Library used by the database/services connection.
545
546 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
547 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
548 services connection.
549
550 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
551 or param name is not a valid SQL identifier.
552
553 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
554 view of whether the text box should be editable when no DataSource is specified.
555 TIBLookupComboEditBox has been updated to workaround this problem. As long as
556 ReadOnly is false, the text box is editable when no DataSource is specified.
557
558 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
559 the FBLIB environment variable. If you do not want to permit this then you
560 must modify the Register procedure in the design/IBDBReg.pas unit to remove
561 this setting.
562
563 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
564
565 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
566 Utf8EscapeControlChars
567
568 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
569
570 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
571 all previous copies of the IBX source code tree before installing this release.
572
573 The IBX packages used by most users have not changed, with one exception. The
574 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
575 to use the IBServices unit in your applications, please add the iblegacyServices
576 to the list of dependencies. To do this, open the Project Inspector and select
577 Add->New Requirement and select "ibLegacyServices" from the list of available
578 packages.
579
580 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
581 the IBServices unit providing what is intended to be a clearer and easier to
582 use set of IB Services components. See Chapter 10 of the IBX User Guide for
583 more information and the guide to "Firebird Service Management Using IBX".
584 As indicated above, the legacy services components are still available and
585 provided in a separate package. There is no need to update working applications
586 using the older versions except for an additional package dependency.
587
588 2. The IBX packages and source code tree have been re-organised in an attempt to
589 finally get rid of the "duplicate ppu" warnings. This re-organisation should
590 not affect existing users. Section 2.3 of the IBX User Guide describes the
591 new set of IBX packages.
592
593 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
594 updated to use the new Services API components.
595
596 4. The iblocal package has been updated to use the new Services API components.
597
598 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
599 TIBXSecurityService. It had been wrongly classified in the previous version
600 as a per database configuration item. It is global to a server and hence
601 correctly positioned as part of the Security Package. In the DBAdmin example,
602 the setting has moved to the mappings page.
603
604 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
605 are ignored.
606
607 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
608 closed before the database is dropped. Before and After Disconnect event handlers
609 are also fired.
610
611 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
612 is started and not just the first time.
613
614 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
615 depenendency with comp type.
616
617 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
618
619 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
620 then this is recognised and not ignored.
621
622 12. TIBDataSet, TIBQuery, TIBTable: additions:
623 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
624 function GetPerfStatistics(var stats: TPerfCounters): boolean;
625 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
626
627 GetRowsAffected returns the affected row counts from the last insert/update/delete
628 if EnableStatistics = true then GetPerfStatistics returns the current stats
629 counters for the select query. Note: stats accumulate after each fetch from
630 the database. To get total query cost after open, call the "Last" method
631 and then GetPerfStatistics.
632
633 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
634
635 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
636 in parenthesises.
637
638 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
639 SQL identifiers are always delimited by double quotes. If false, then they are
640 only delimited if the identifier is a reserved word, contains lower case or special
641 characters. Set this property to true to retain previous behaviour.
642
643 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
644 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
645
646 16. TIBDataSet, TIBQuery, TIBTable: addition:
647 property MasterDetailDelay: integer {defaults to zero}
648
649 When non-zero and the dataset is a detail table referencing a master table
650 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
651 then a synchronisation delay is added (in milliseconds) between the master
652 row changing and the detail dataset being re-opened. If the master dataset
653 is scrolled before the delay expires then the delay is reset. This can be used
654 to avoid performance overheads when scrolling through a large master dataset.
655
656 Note: uses fptimer and hence requires a thread manager. Under Linux the
657 chreads unit must be included in your project. TTimer is not used in order
658 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
659
660 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
661 with Extract Option eoDatabase.
662
663 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
664 When a deLayoutChanged event is reported on the ListSource dataset, the
665 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
666 relationship with the control's datasource (master).
667
668 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
669
670 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
671 stubs. Pedantic fix really, as procedures output in dependency order anyway.
672
673 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
674 DDL (Firebird 3 and later only).
675
676 22. TIBLookupComboBox Autocomplete Fixes:
677 i. Only appended text is now selected after autocomplete.
678 ii. Uppercase keys no longer ignored for autocomplete.
679 iii. Retain Prefix case is now honoured correctly.
680 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
681 before autocomplete performed. i.e. behaviour now the same as when
682 no DataSource assigned.
683
684 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
685 between SQL statements.
686
687 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
688 ObjectNames are converted to upper case before matching against metadata object
689 names, unless the objectname is delimited by double quotes, in which case, the
690 double quotes are removed and the remaining string is used (unmodified) to match
691 against the metadata object name.
692
693 If true then the ObjectName is used as is without modification and matched
694 against the metadata object name. No attempt is made to remove double quotes.
695
696 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
697 with eoTrigger, these extract types can be used to select only Database Triggers,
698 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
699
700 26. TIBXScript: If an exception occurs during the processing of a statement, the
701 statement separate character is now reset to the default (';').
702
703 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
704
705 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
706 a commit or reconnect statement and instead activated only when next SQL statement
707 is executed.
708
709 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
710
711 30. TIBXScript: case insensitive regex now used when matching statements instead of
712 converting statement to upper case.
713
714 31. TIBExtract: metadata comments now supported. New published property
715 IncludeMetaDataComments (default true). If true then metadata comments included
716 in extracted DDL. New Extract Object member eoComments. This may be used with
717 ExtractObject method to list all metadata comments.
718
719 32. TIBExtract: ListObjectNames method added.
720
721 33. Updated Database component editor to support additional connection string
722 types.
723
724 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
725
726 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
727 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
728 RELEASE.
729
730 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
731
732 1. IBExtract: Identity columns - add additional check for null column for generator name.
733
734 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
735 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
736 information). However, this is also a very useful mechanism for returning updated computed by
737 column values. Values returned as a result of executing an Insert or Update statement
738 replace existing values in the current row for each corresponding column.
739
740 Previously, if a dataset's select query included read only (computed by) fields then
741 an automatic row refresh was performed after an insert or update query had been processed,
742 irrespective of the setting of the "ForcedUpdates" property. This has changed such
743 that an automatic refresh is no longer performed if an insert or update query contains
744 a returning clause that updates one or more fields on the current row. A full row
745 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
746 field values and the select query contains read only fields. Use of Insert/update
747 returning should be significantly more efficient than executing a refresh query.
748
749 This behaviour change is intended to be backwards compatible and there should be no need to change
750 existing programs, other than to improve performance by using the new capability.
751
752 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
753 they are called when the dataset row is being deleted, there is no value in
754 updating the current record from the query result. Instead, a new event handler
755 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
756 an OnDeleteReturning event handler is provided then it is called with the IResults returned
757 by the query. The event handler can then interrogate the query results and
758 perform whatever action is necessary. For example to confirm, to the user,
759 the deletion of a row with the returned values.
760
761 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
762 any Computed By or Identity Columns. The IBTables example has been updated to
763 illustrate the computation of the employee Full Name on update.
764
765 5. TIBTable: The GeneratorField property is now published.
766
767 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
768 When InsertSQL is generated, the Identity columns are not included in the list of values to
769 be inserted. A RETURNING clause is added to the insert statement to return the value of
770 each Identity column after the insert is executed.
771
772 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
773 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
774 Insert..Returning clause.
775
776 8. TIBGenerator: small performance improvement by not preparing query each time
777 a new value is generated.
778
779 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
780
781 10. Property editors will now sync table name to a System Table when "Include System
782 Tables" is selected and the query is for a System Table.
783
784 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
785 values are no longer converted to milliseconds from TDateTime and then back again
786 to TDateTime (the conversion to milliseconds is the default TDataset approach).
787
788 12. Property Editors handling of Stored Procedures.
789 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
790 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
791 query).
792 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
793
794 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
795 can be used to select a package. If non-empty, the stored procedure name is
796 expected to be a stored procedure defined in the specified package and the
797 generated SQL will be as required for a stored procedure located in a package.
798
799 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
800 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
801 which a stored procedure can be selected. With no package name selected, non-package
802 stored procedures are listed.
803
804 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
805 for password on reconnect.
806
807 16. TIBDatabase: use IAttachment for connection default character set id, code page
808 and character set name.
809
810 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
811 DB info lookups"
812
813 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
814
815 19. Add a property Editor for TIBUpdate.RefreshSQL.
816
817 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
818 parameters. This stops an exception being raised when the field cannot be
819 located in the record buffer.
820
821 21. Property Editors now automatically include System Tables when opened and when the query table
822 is a System Table.
823
824 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
825 This avoids errors due to a stale SQRB or SRB being used for the next query.
826
827 23. IBServices: Service attach parameters now include "expected_db". This is used to
828 add the SPB item isc_spb_expected_db. This names a database using
829 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
830 database. examples/services re-written to illustrate use of "expected_db".
831
832 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
833 This avoids truncated backups when the server returns a timeout (busy) response.
834
835 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
836
837 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
838 databasenames. These are respectively expanded to the local system's temp directory
839 (including trailing delimiter) or to a prescribed data directory (including
840 trailing delimiter). Under Unix systems the data directory is a hidden directory
841 in the user's home directory. The hidden directory name is either the string returned
842 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
843 Under Windows, the directory is the same as the Data Directory as decribed
844 above but instead prefixed by the User's application data path. These may be
845 used to improve application portability for Personal Databases.
846
847 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
848 this has not worked for a long time and is not useful either. FieldDefs should be
849 managed using the Fields Editor as with any other dataset. To access the fields
850 editor for a TIBTable component, double click on the component. The fields editor
851 is then displayed.
852
853 28. TIBDatabaseInfo: new properties/function
854 * DateDBCreated (returns date/time database created)
855 * TransactionCount (returns no. of active transactions)
856 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
857 * PagesFree (Firebird 3 or later)
858 * PagesUsed (Firebird 3 or later)
859 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
860 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
861
862 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
863
864 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
865
866 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
867 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
868
869 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
870 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
871 firing during backup and restore.
872
873 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
874 for verbose output using the new property "StatisticsRequested".
875 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
876
877 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
878
879 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
880 palette. This uses the online validation feature added in Firebird 2.5. The
881 services's properties enable inclusion/exclusion of tables and indexes using
882 regular expressions. See.
883 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
884
885 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
886 option on a database.
887
888 37. TIBCustomService: Assign method implemented to allow copying of service login
889 context between service API components. "Detach" method now only detaches
890 service when last reference to the service interface detaches. Tidy up of
891 code for SetActive and Attach methods including password hiding.
892
893 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
894 and used to determine the auth method and protocol used for the connection.
895
896 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
897 a Create Database Statement generated by IBX.
898
899 40. All IBServices now have an additional published property "PortNo". This may
900 be set to a non-standard port number when necessary. If zero then the default
901 port number is used.
902
903 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
904 and not just the mouse.
905
906 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
907
908 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
909 image index and selected image index for each node to be set from a database field.
910
911 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
912 then database schema includes grants to all users. If not present then the
913 only user grants included are those to User PUBLIC.
914
915 45. TIBTreeView: performance improvement. When expanding include both expanded node
916 and child nodes in dataset.
917
918
919 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
920
921 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
922 changes.
923
924 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
925 Bug could result in truncated multi-byte character set values.
926
927 3. Changes consequential on moving fbintf character set utility functions from
928 IFirebirdAPI to IAttachment.
929
930 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
931
932 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
933 results in autocomplete ignoring prefix text.
934
935 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
936 entering a new name into the text box.
937
938 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
939 Firebird rather than recomputing it.
940
941 8. Property Editor positioning tidy up: All IBX Property editors should now be
942 screen centre. Previously some were "poDesigned" which may be inappropriate
943 for multi monitor desktops.
944
945 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
946
947 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
948 a transaction and always reset the object.
949
950 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
951
952 13. TIBXScript: Allow for override of database filename in Create Database statements.
953
954 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
955 to a gbak format archive.
956
957 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
958
959 16. IBLocaldb: Drop database if error creating an empty database.
960
961 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
962 unless selected node not in current dataset.
963
964 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
965 to TIBCustomService, and IBlocalDB code tidy up.
966
967 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
968 behaviour due to uninitialised variable.
969
970 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
971 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
972
973 21. IBSQL: When Database changed ensure that all resources are freed.
974
975 22. IBCustomDataset: When database changed ensure that queries an unprepared.
976
977 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
978 * Line Wrap on SQL Token boundaries (on user command)
979 * auto-complete table names in drop down list of table names
980 * Double click on tablename or field name adds to SQL text
981
982 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
983
984 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
985 TVariantArray. Seems to avoid memory corruption in Windows (probably a
986 workaround for a problem in fpc 3.0.4 win64).
987
988 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
989
990 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
991
992 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
993
994 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
995 include remote system name.
996
997 2. TIBExtract: No longer include comment header and COMMIT statement for empty
998 tables when data included in output.
999
1000 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
1001 and timing information to be written to stdout. This may be used to locate
1002 performance bottlenecks.
1003
1004 4. SQLParser: only call "OnChanging" event handler when value is different.
1005
1006 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
1007
1008 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
1009 that BindFields is called when the query is next activated. Avoids FieldName
1010 not found error.
1011
1012 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
1013 purpose and allows the programmer to define any action they want for Update, Insert
1014 or Delete. This may be complex SQL (similar to a Trigger), application specific
1015 filtering of updates, or use of statements such as Grant or Revoke instead of
1016 normal DML. See User Manual for more information.
1017
1018 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
1019
1020 1. TIBEvents: Fix uninitialised variable that could result in lost events.
1021
1022 2. TIBExtract: Added support for FB3 "USAGE" privilege.
1023
1024 3. TIBExtract: data formatted as Charset set "octets" is now output using
1025 hexadecimal notation.
1026
1027 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
1028 using a simple XML format.
1029
1030 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
1031 grants to these objects.
1032
1033 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
1034 dependency problems restoring complex databases.
1035
1036 7. TIBXScript: This component has been restructured to allow for the processing of
1037 embedded XML in INSERT statements and to support interactive sources in addition
1038 to non-interactive data sources such as files.
1039
1040 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
1041
1042 9. TIBXScript: ISQL compatiable Set statements are now supported:
1043 SET SQL DIALECT
1044 SET TERM
1045 SET AUTODDL
1046 SET BAIL
1047 SET ECHO
1048 SET COUNT
1049 SET STATS
1050 SET NAMES <character set>
1051
1052 10. IBVersion unit added to hold current IBX Version Number information.
1053
1054 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
1055 and domain definitions.
1056
1057 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
1058 fully supported.
1059
1060 13. TIBExtract: when a database dump includes data, the generator values are now also set.
1061
1062 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
1063
1064 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
1065
1066 See also doc/IBX4LazarusGuide.pdf for important information on
1067 upgrading to IBX2.
1068
1069 1. Size property of TIBStringField is now the width in characters of the field
1070 and not the byte length. This applies only to multi-byte character sets such
1071 as UTF8. The original approach aligned with TStringField. However, the TStringField
1072 code is not recognised as a bug and hence this change to align the behaviour.
1073 The TStringField change is expected in fpc 3.2.0.
1074
1075 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
1076 true (default) then Size property value saved in the lfm is ignored. Size is
1077 always set from the dynamic information read from the database. It is unclear
1078 why anyone would want to override this and set Size to false.
1079
1080 3. ibxscript: should now handle correctly a Case..End statement within a procedure
1081 block.
1082
1083 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
1084 exist when an attempt is made to connect to it (run time only) then an attempt
1085 is made to create the database.
1086
1087 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
1088 has been successfully created as a result of a call to CreateDatabase or when
1089 creating a database after it was found not to exist.
1090
1091 6. DBControlGrid: a race condition could result in the wrong row image being
1092 written to the cache. This has been avoided by a trip round the message
1093 loop before rendering the row image.
1094
1095 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
1096 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
1097 known to risk corrupt rendering of row images when the control is first
1098 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
1099 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
1100
1101 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
1102 a TDateEdit control located on an editor panel.
1103
1104 9. TIBExtract: brought up-to-date plus many bug fixes.
1105
1106 10. DBControlGrid: Removed memory leak when updating rows.
1107
1108 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
1109
1110 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
1111
1112 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
1113 when target codepage is CP_NONE. This is a workaround for
1114 http://bugs.freepascal.org/view.php?id=30622.
1115
1116 2. DBLog option removed from TIBStatisticalService - not supported by server
1117 since Firebird 1.5.
1118
1119 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1120 similar.
1121
1122 4. IBCodePage: updated mapping between codepages and character id.
1123
1124 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1125 Firebird. Character sets with a char width of two are not UTF16.
1126
1127 6. Strings received from the database are now always transliterated into UTF8
1128 regardless of the database character set or connection character set. This
1129 is for compatibility with the LCL.
1130
1131 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
1132
1133 1. IBBlob: Defer reading of blob until read method called. This avoids having to
1134 read in an entire blob just to get the size of the blob. General performance
1135 improvement when opening datasets containing blobs.
1136
1137 2. Clearing a Blob now sets the corresponding field's modified flag.
1138
1139 3. IBLookupCombo: When not performing auto-complete, original query sort order
1140 is now used.
1141
1142 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1143 determined.
1144
1145 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1146
1147 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1148 lazarus 1.6.0
1149
1150 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
1151 compilation error.
1152
1153 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
1154
1155 1. No character set specified for connection: when a text blob is retrieved, the
1156 character set is determined by looking up the native character set using then
1157 Firebird API. Otherwise a text mode blob is assumed to have the same character
1158 set as the connection.
1159
1160 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1161 for Login Dialog returing a change to the database path.
1162
1163 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1164 to be changed from that given in the TIBDatabase/TIBServer component and for the
1165 entered value to be saved on a project specific basis (design time only).
1166
1167 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1168 column fieldname. If they are the same then it is acts as a look up for the KeyValue
1169 Otherwise, it sets the column text to the selected ListField Value.
1170
1171 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1172 column width.
1173
1174 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1175 and a case insensitive search is requested.
1176
1177 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1178 or column ListSource.
1179
1180 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1181 unprepare) when closing and the text has not changed.
1182
1183 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1184 Less likely to cause a cursor re-use error on Windows.
1185
1186 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1187 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1188
1189 11. TIBTreeView: Guard against nil destination on record changed
1190
1191 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1192 string type with the code page set to reflect the returned field encoding after
1193 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
1194 earlier versions.
1195
1196 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1197 will now result in transliteration to the code page specified for the Firebird driver
1198 if the assigned string has a different code page. FPC 3.0.0 onwards only.
1199
1200 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1201 is ignored and the lc_ctype value, when the database is opened, is set to align with
1202 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1203 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1204 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1205 the GETACP is used to determine the Windows code page.
1206
1207 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1208 name used as the lc_ctype when the database was opened. Only valid while the
1209 Database is connected.
1210
1211 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1212 id that corresponds to the DefaultCharSetName.
1213
1214 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1215
1216 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1217 path is given and database attach fails due to access permission issues on the
1218 temp directory or security database, then the attach is retried with "localhost:"
1219 prefixing the databasename. This should avoid problems when the database has to
1220 be accessed by a local (e.g. classic) server and libfbembed is used.
1221
1222 2. Windows: revised search order for Firebird DLL:
1223 i. The Firebird Embedded Server in the application Directory.
1224 ii. If the FIREBIRD environment variable is set then the directory this
1225 points to is searched for the FB Client DLL and then then underlying
1226 "bin" directory.
1227 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1228 is used to locate the Firebird installation directory and the underlying
1229 "bin" directory is searched for the FB Client DLL.
1230 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1231 are searched for the FB Client DLL.
1232 v. The PATH Environment variable is used to search for the FB Client DLL.
1233 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1234
1235 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1236 See doc/readme.scriptengine and example applications.
1237
1238 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1239 simplify the use of the embedded firebird server on both Linux and Windows platforms.
1240 See dpc/readme.localdatabase and example applications.
1241
1242 5. IBDynamicGrid: Reordering on column header click should now also work for
1243 dynamic columns.
1244
1245 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1246 between incrementing/decrementing the lock count and signalling the event.
1247
1248 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1249
1250 1.3.2 was never formally released and only made available as beta copies.
1251
1252 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1253
1254 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1255
1256 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1257
1258 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1259 i.e. when it is a calculated field
1260
1261 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1262 This problem was due to a race condition between recalculating row heights and
1263 determining which row was selected by the mouse click. The row height calculation
1264 is now deferred by an extra trip round the message loop allowing the row to
1265 be always calculated on the current grid layout rather than risking it being
1266 calculated on the grid layout after the expanded row has been shrunk.
1267
1268 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1269 Windows.
1270
1271 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1272 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1273 to be determined at runtime. See doc/readme.charactersets.html.
1274
1275 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1276 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1277
1278 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1279 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1280 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1281
1282 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1283 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1284 implies no truncation.
1285
1286 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1287
1288 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1289 (avoids "Not in Edit Mode" error).
1290
1291 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1292
1293 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1294 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1295
1296 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1297
1298 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1299
1300 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1301
1302 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1303
1304 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1305
1306 1. OnCloseUp Event Handler added to TDBLookupProperties
1307
1308 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1309 problem with row size when exception is called.
1310
1311 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1312
1313 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1314 in a TCustomComboBox and ignores return key if in a TCustomMemo
1315
1316 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1317 keyed in i.e. when autocomplete not performed
1318
1319 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1320 console mode applications with all LCL required functions (builtin dialogs and
1321 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1322 not included in your project, IBX should compile and link with a console mode program.
1323 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1324 console mode application or the IDE will automatically assume that your
1325 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1326
1327 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1328 to use the built in dialogs and cursor management. IBDialogs is
1329 included by default if "ibexpress" is in your project source's "uses" clause.
1330 This should be the case for all projects created through the IDE. This is why
1331 you do not want to add the ibexpress package to console mode applications. The
1332 ibexpressconsolemode package has been created to allow console mode programs
1333 to avoid adding LCL dependencies when using IBX, while still having the
1334 unit search paths set up correctly.
1335
1336 Existing users should check to ensure that the "ibexpress" unit is included in
1337 each project's source file (*.lpr).
1338
1339 You may find that in order for the IDE to recognise that ibexpressconsolemode
1340 exists, you have to first open the package in the IDE and then close it. This
1341 adds it to the most recently accessed packages list. To make it permanently
1342 available, add the package name to lazarus' staticpackages.inc file.
1343
1344 Thanks to Julio Jiménez for suggesting support of console mode.
1345
1346 7. SQL Parser can now accept quoted strings that include new lines
1347
1348 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1349 of text on start of edit. This is particularly useful when tabbing to a
1350 column and then inserting text.
1351
1352 9. New Examples provided for IB Services and ISQLMonitor.
1353
1354 10. Fix error when writing to blob streams that recorded only the last buffer
1355 write in the blob stream. In most cases, this did not cause a problem as the
1356 IB Blob Stream is written in a single write. However, with the TDBImage, write
1357 of a graphic type prefix was lost which caused a problem when the image could
1358 not be automatically recognised.
1359
1360 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1361 already open" errors due to random numbers used for the cursor name being identical.
1362
1363 12. IBTable: corrected error that could result in an "Index out of bounds" error
1364 when opening the table and the Primary Key is the last or only column in the
1365 table. Thanks to Rick Hoover for the fix.
1366
1367 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1368 of "UTF-8", and update list of available database character sets. Existing
1369 users should check the current lc_ctype setting in their applications.
1370
1371 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1372
1373 1. Firebird Services: avoid List Index error when opening a service with an
1374 empty Params property.
1375
1376 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1377 Link now set up in Loaded method - avoids occasional failure to apply
1378 SQL markup on initial open.
1379
1380 3. "Employees" example performance improvements when scrolling.
1381
1382 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1383 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1384 random image cached).
1385
1386 5. DBControlGrid: Should now react to changes in panel height at run time.
1387
1388 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1389 even when further rows exist.
1390
1391 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1392 always be derived from panel height and setting this property can cause confusion.
1393 Note for existing projects: to avoid a missing property error at run time,
1394 each form using the DBControlGrid must be opened, updated and saved in the IDE
1395 in order to remove the property value from the lfm.

1398 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1399
1400 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1401 call Prepare before setting parameter values.
1402
1403 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1404
1405 3. Code tidyup and more robust handling of dsql information result vector.
1406
1407 4. Support for centralised handling of transaction status changes. TIBTransaction
1408 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1409 and "AfterExecQuery". The first three are called after the same event is called
1410 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1411 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1412 enable monitoring of transaction status changes for a given transaction to be
1413 handled in a single place. For example, when a change to the dataset occurs
1414 an indicator can be set that shows the user that in order to save changes,
1415 the transaction should be committed. Rather than doing this per dataset, this
1416 can now be done per transaction.
1417
1418 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1419 the dataset is scrolled. However, any changes to the current row are, by default,
1420 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1421 have a new property "DataSetCloseAction" that adds automatic posting of changes
1422 on dataset close. If this property is set to dcDiscardChanges (default) then the
1423 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1424 then IBX will attempt to post any unsaved changes before the dataset is closed
1425 (and after the BeforeClose event handler is called). The exception is when the
1426 dataset is being closed as a result of a transaction rollback. In this case,
1427 no action is taken and any unsaved changes are discarded. This avoids both
1428 unnecessary overhead and the risk that a validation error may occur in the Post
1429 raising an exception and thereby preventing a rollback.
1430
1431 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1432 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1433 width. Display Widths are now corrected by dividing by the max byte width per character.
1434 For UTF8 character sets, the byte width is four and hence the Display Width will be
1435 the byte width divided by 4. The byte width of each character set is determined
1436 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1437 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1438
1439 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1440
1441 8. IBLookupComboEditBox: List should now always be restored to full list when the
1442 control loses focus. Default Key press default interval reduced to 200ms.
1443
1444 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1445 when dataset rows are less than visible rows.
1446
1447 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1448 does not exist or DataSet is empty. More responsive on dataset open. New event
1449 OnRestorePosition. Column sort disabled if no header row.
1450
1451 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1452 while dataset state is dsInsert. Avoids posting errors.
1453
1454 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1455 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1456
1457 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1458
1459 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1460 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1461 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1462 always "posts" the current record regardless or whether or not it may be more appropriate
1463 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1464 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1465 as the first action of the "Post" method and allows the handler to convert the Post
1466 into a Cancel if that is the appropriate action on moving to a different row. This is
1467 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1468 raised here, but it may still be more appropriate to validate a post and signal
1469 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1470
1471 15. On Unix derived systems, the Firebird library name can now be given as a colon
1472 separated list. Each library name on the list is tried in turn, in left to right
1473 order with the first found being used as the firebird library. By default, on Linux,
1474 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1475 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1476
1477 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1478 then it will still attempt to access the database via the Firebird Server and will
1479 require a username and password. If only the pathname is given, then the username
1480 and password should be omitted and the unix file permissions are used to grant
1481 access.
1482
1483 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1484
1485 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1486 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1487 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1488 corresponds to a row of the linked DataSource. Any data aware control on the
1489 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1490
1491 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1492 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1493 takes place during database access. This may be useful when there are performance issues with
1494 the change of cursor. Setting the property to false suppresses the change of cursor.
1495
1496 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1497 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1498 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1499 making all changes permanent immediately rather than when the transaction is explicitly
1500 committed.
1501
1502 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1503 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1504

1509 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1510
1511 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1512 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1513 "Where" and "Having" clauses to implement user specified filters of arbitrary
1514 complexity.
1515
1516 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1517 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1518 These are:
1519
1520 - TIBLookupComboEditBox
1521 - TIBDynamicGrid
1522 - TIBTreeview
1523
1524 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1525 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1526 to revise the available list and restrict it to items that are prefixed by the
1527 typed text (either case sensitive or case insensitive). Autoinsert allows a
1528 newly typed entry to be added to the list dataset and included in the available
1529 list items.
1530
1531 TIBDynamicGrid is a TDBGrid descendent that provides for:
1532 - automatic resizing of selected columns to fill the available row length
1533 - automatic positioning and sizing of a "totals" control, typically at the
1534 column footer, on a per column basis.
1535 - DataSet resorting on header row click, sorting the dataset by the selected column.
1536 A second click on the same header cell reversed the sort order.
1537 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1538 is automatically expanded and a panel superimposed on it. The panel can have any
1539 number of child controls, typically data aware controls with the same datasource
1540 as the grid allowing for editing of additional fields and more complex editors.
1541 - Reselection of the same row following resorting.
1542 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1543 Its properties are specified on a per column basis and allows for one or more
1544 columns to have their values selected from a list provided by a dataset.
1545 Autocomplete and autoinsert are also available. The existing picklist editor
1546 is unaffected by the extension.
1547
1548 TIBTreeView is a data aware TCustomTreeView.
1549
1550 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1551 zero scale will no longer return an error. An Int64 will be returned instead.
1552
1553 4. TIBTransaction now has events for Before and After Transaction End and a new function
1554 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1555
1556 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1557 repeated multiple times.
1558
1559 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1560 check used to get in the way of using Stored Procedures, and "Update or Insert"
1561 statements.
1562
1563 7. Insert, Modify and Delete property Editors now support Query Generation from
1564 Stored Procedures.
1565
1566 8. Three new examples illustrate the use of the new IB Controls
1567
1568
1569 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1570
1571 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1572 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1573 Gabor Boros for reporting this problem and for testing the improvements).
1574
1575 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1576 See readme.field+param.names in the doc folder.
1577
1578 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1579 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1580
1581 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1582
1583 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1584 actions.
1585
1586 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1587 thanks to Yuriy Kopnin for pointing this out).
1588
1589 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1590
1591 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1592 for both fields and parameter setting.
1593
1594 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1595 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1596
1597 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1598 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1599
1600 11. TIBTable now has a property editor for "MasterFields"
1601
1602 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1603 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1604
1605 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1606 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1607

1609 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1610
1611 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1612
1613 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1614
1615 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1616 it is null. This allows for alternative user defined setting of the generator
1617
1618 Many thanks to Julio Jiménez for this fix
1619
1620 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1621 and suggests that the user may have forgotten to install it.
1622
1623 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1624
1625 1. Conditional compilation used to limit registration of TIntegerField to
1626 Lazarus versions less than 1.1
1627
1628 2. When a database connection is created, character set is now by default set
1629 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1630 1250 to 1254.
1631

1633 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1634
1635 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1636
1637
1638 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1639
1640 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1641 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1642
1643 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1644 package is changed to do this (which it should do).
1645
1646 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1647
1648 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1649
1650 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1651
1652 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1653
1654 4. Property editors should now correctly resize.
1655
1656 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1657 (restored original functionality)
1658
1659 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1660 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
