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 ';'.

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

1386 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1387
1388 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1389 call Prepare before setting parameter values.
1390
1391 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1392
1393 3. Code tidyup and more robust handling of dsql information result vector.
1394
1395 4. Support for centralised handling of transaction status changes. TIBTransaction
1396 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1397 and "AfterExecQuery". The first three are called after the same event is called
1398 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1399 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1400 enable monitoring of transaction status changes for a given transaction to be
1401 handled in a single place. For example, when a change to the dataset occurs
1402 an indicator can be set that shows the user that in order to save changes,
1403 the transaction should be committed. Rather than doing this per dataset, this
1404 can now be done per transaction.
1405
1406 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1407 the dataset is scrolled. However, any changes to the current row are, by default,
1408 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1409 have a new property "DataSetCloseAction" that adds automatic posting of changes
1410 on dataset close. If this property is set to dcDiscardChanges (default) then the
1411 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1412 then IBX will attempt to post any unsaved changes before the dataset is closed
1413 (and after the BeforeClose event handler is called). The exception is when the
1414 dataset is being closed as a result of a transaction rollback. In this case,
1415 no action is taken and any unsaved changes are discarded. This avoids both
1416 unnecessary overhead and the risk that a validation error may occur in the Post
1417 raising an exception and thereby preventing a rollback.
1418
1419 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1420 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1421 width. Display Widths are now corrected by dividing by the max byte width per character.
1422 For UTF8 character sets, the byte width is four and hence the Display Width will be
1423 the byte width divided by 4. The byte width of each character set is determined
1424 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1425 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1426
1427 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1428
1429 8. IBLookupComboEditBox: List should now always be restored to full list when the
1430 control loses focus. Default Key press default interval reduced to 200ms.
1431
1432 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1433 when dataset rows are less than visible rows.
1434
1435 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1436 does not exist or DataSet is empty. More responsive on dataset open. New event
1437 OnRestorePosition. Column sort disabled if no header row.
1438
1439 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1440 while dataset state is dsInsert. Avoids posting errors.
1441
1442 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1443 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1444
1445 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1446
1447 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1448 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1449 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1450 always "posts" the current record regardless or whether or not it may be more appropriate
1451 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1452 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1453 as the first action of the "Post" method and allows the handler to convert the Post
1454 into a Cancel if that is the appropriate action on moving to a different row. This is
1455 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1456 raised here, but it may still be more appropriate to validate a post and signal
1457 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1458
1459 15. On Unix derived systems, the Firebird library name can now be given as a colon
1460 separated list. Each library name on the list is tried in turn, in left to right
1461 order with the first found being used as the firebird library. By default, on Linux,
1462 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1463 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1464
1465 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1466 then it will still attempt to access the database via the Firebird Server and will
1467 require a username and password. If only the pathname is given, then the username
1468 and password should be omitted and the unix file permissions are used to grant
1469 access.
1470
1471 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1472
1473 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1474 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1475 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1476 corresponds to a row of the linked DataSource. Any data aware control on the
1477 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1478
1479 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1480 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1481 takes place during database access. This may be useful when there are performance issues with
1482 the change of cursor. Setting the property to false suppresses the change of cursor.
1483
1484 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1485 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1486 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1487 making all changes permanent immediately rather than when the transaction is explicitly
1488 committed.
1489
1490 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1491 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1492
1493 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1494
1495 Development version only.
1496
1497 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1498
1499 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1500 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1501 "Where" and "Having" clauses to implement user specified filters of arbitrary
1502 complexity.
1503
1504 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1505 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1506 These are:
1507
1508 - TIBLookupComboEditBox
1509 - TIBDynamicGrid
1510 - TIBTreeview
1511
1512 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1513 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1514 to revise the available list and restrict it to items that are prefixed by the
1515 typed text (either case sensitive or case insensitive). Autoinsert allows a
1516 newly typed entry to be added to the list dataset and included in the available
1517 list items.
1518
1519 TIBDynamicGrid is a TDBGrid descendent that provides for:
1520 - automatic resizing of selected columns to fill the available row length
1521 - automatic positioning and sizing of a "totals" control, typically at the
1522 column footer, on a per column basis.
1523 - DataSet resorting on header row click, sorting the dataset by the selected column.
1524 A second click on the same header cell reversed the sort order.
1525 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1526 is automatically expanded and a panel superimposed on it. The panel can have any
1527 number of child controls, typically data aware controls with the same datasource
1528 as the grid allowing for editing of additional fields and more complex editors.
1529 - Reselection of the same row following resorting.
1530 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1531 Its properties are specified on a per column basis and allows for one or more
1532 columns to have their values selected from a list provided by a dataset.
1533 Autocomplete and autoinsert are also available. The existing picklist editor
1534 is unaffected by the extension.
1535
1536 TIBTreeView is a data aware TCustomTreeView.
1537
1538 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1539 zero scale will no longer return an error. An Int64 will be returned instead.
1540
1541 4. TIBTransaction now has events for Before and After Transaction End and a new function
1542 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1543
1544 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1545 repeated multiple times.
1546
1547 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1548 check used to get in the way of using Stored Procedures, and "Update or Insert"
1549 statements.
1550
1551 7. Insert, Modify and Delete property Editors now support Query Generation from
1552 Stored Procedures.
1553
1554 8. Three new examples illustrate the use of the new IB Controls
1555
1556
1557 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1558
1559 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1560 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1561 Gabor Boros for reporting this problem and for testing the improvements).
1562
1563 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1564 See readme.field+param.names in the doc folder.
1565
1566 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1567 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1568
1569 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1570
1571 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1572 actions.
1573
1574 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1575 thanks to Yuriy Kopnin for pointing this out).
1576
1577 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1578
1579 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1580 for both fields and parameter setting.
1581
1582 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1583 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1584
1585 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1586 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1587
1588 11. TIBTable now has a property editor for "MasterFields"
1589
1590 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1591 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1592
1593 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1594 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1595

1597 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1598
1599 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1600
1601 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1602
1603 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1604 it is null. This allows for alternative user defined setting of the generator
1605
1606 Many thanks to Julio Jiménez for this fix
1607
1608 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1609 and suggests that the user may have forgotten to install it.
1610
1611 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1612
1613 1. Conditional compilation used to limit registration of TIntegerField to
1614 Lazarus versions less than 1.1
1615
1616 2. When a database connection is created, character set is now by default set
1617 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1618 1250 to 1254.
1619
1620
1621 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1622
1623 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1624
1625
1626 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1627
1628 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1629 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1630
1631 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1632 package is changed to do this (which it should do).
1633
1634 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1635
1636 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1637
1638 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1639
1640 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1641
1642 4. Property editors should now correctly resize.
1643
1644 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1645 (restored original functionality)
1646
1647 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1648 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
