1 IBX Change Log version (2.6-4 Build 14094) Sat, 21 Oct 2023 15:03:30 +0100
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 IBX Change Log version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100
10
11 1. Update to calls to EInterbaseError to add default code page. Consequential
12 on change to fbintf.
13
14 2. Update some examples to replace test for null date with the NullDate constant
15 instead of zero. This is because Laz 3.0 changes the value of NullDate.
16
17 IBX Change Log version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100
18
19 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
20 with later versions of fpc - later than 3.2.2.
21
22 2. IBUpdateSQL. update internal queries if parent dataset database changed.
23
24 3. IBUpdateSQL: Do not prepare an empty internal query.
25
26 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
27
28 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
29
30 IBX Change Log version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
31
32 1. Maintenance update of 2.6.0. This version is still at beta.
33
34 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
35 See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
36
37 3. ibxscript: When parsing a store procedure or function with a variable name
38 enclosed in doublequotes, the double quotes are no longer removed.
39
40 IBX Change Log version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
41
42 NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
43 AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
44 BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
45 ISSUES TO support@mwasoftware.co.uk
46
47 1. Complete rewrite of internal buffer management in order to improve performance
48 and maintainability. Highlights:
49
50 * Extending the size of the buffer pool no longer has to copy the entire record
51 cache. Instead, a new extent is simply added to the buffer pool.
52 * A memory to memory copy of each display buffer now is avoided when scolling the
53 dataset.
54 * A separate set of buffers is now used for calculated fields. This avoids
55 having to keep copies of calculated field values in the buffer cache.
56 * Compact bitmaps are used to record null status and need to refresh in each
57 buffer.
58 * Display buffer type changed from PChar to TRecordBuffer in line with change of
59 buffer type in FCL-DB.
60
61 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
62 to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
63
64 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
65 If either or both of these flags are set at design time (using the fields editor)
66 then this forces a row refresh on respectively insert or update, or both, when the
67 corresponding field is not present in an SQL RETURNING clause.
68
69 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
70 maintainability and readability and to add identification of primary key fields.
71
72 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
73 as a refresh of the current row. However, this is different behaviour to that described
74 in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
75 the dataset from the underlying database, and attempts to reposition the cursor on
76 the same record as it was". IBX now complies with the FPC definition of Refresh.
77
78 6. A progammatic Row Refresh should no longer be required.
79 Use Insert/Update... returning to refresh any fields that may change following an
80 insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
81 on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
82 for the field at Design Time to force a row refresh if not in the returning clause.
83
84 7. It should now be possible to insert a row into an empty unidirectional dataset.
85
86 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
87 This gives the number of buffers in the initial block for the buffer pool in
88 bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
89 in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
90 for small datasets.
91
92 IBX Change Log version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
93
94 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
95
96 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
97
98 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
99
100 IBX Change Log version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
101
102 1. TIBTransaction: new properties
103 property TransactionID: integer read GetTransactionID;
104 property IsReadOnly: boolean read GetIsReadOnly;
105 {published}
106 property TransactionName: string read FTransactionName write SetTransactionName;
107
108 2. IBCustomDataset: per row blob and array buffer cached clear before processing
109 Insert or Update...Returning. This allows blobs and arrays to be returned
110 by the statement.
111
112 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
113
114 4. TransactionName initialised to a newly generated GUID if empty.
115
116 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
117 for the fbintf package's journaling capability. TIBJournal is used to set the
118 file path and filename for the journal file and to Enabled (start journaling) and
119 disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
120 more information, and comments in IBJournal.pas.
121
122 6. TIBDatabase.InternalTransaction is now a read only transaction.
123
124 7. Bug fix: blob id no longer set to null on update when blob has not been
125 retrieved.
126
127 8. Row auto refreshed on update/insert if blob or array field updated and field
128 not in a returning clause.
129
130 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
131 buffer overhead and avoids problem when refresh query has a different column
132 count to select query i.e. incorrectly changing number of columns.
133
134 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
135
136 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
137 string. Note that the Version property returns an InterBase compatible version string.
138
139 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
140
141 IBX Change Log version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
142
143 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
144 This is for compatibility with Firebird 5 where Update...Returning can return
145 a cursor.
146
147 IBX Change Log version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
148
149 1. Add try-..except check when initially loading library in IDE. This should
150 ensure that IDE continues to load even when a failure occurs in IBX load
151 library.
152
153 2. IBXScript: now recognises a CASE...END block within a stored procedure and
154 hence will correctly detect end of the outer containing block when the block
155 contains a SELECT ... CASE ... END construct.
156
157 3. IBExtract: some further tidying up to remove extraneous white space.
158
159 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
160 errors when extra elements are added to DB.TFieldType.
161
162 5. IBUpdate: updated to reflect changes to ISQLParam.
163
164 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
165
166 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
167
168 8. IBSQL: Support for scrollable cursors added (note: local databases only)
169
170 IBX Change Log version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
171
172 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
173 exception of those defined to be one byte wide e.g. DBImplementationNo.
174
175 2. TIBSQL: Batch Update/Insert support added.
176
177 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
178 is no longer automatically converted to upper case when it is syntactically a
179 SQL Identifier. This is to support the use of stored procedures defined e.g.
180 as CREATE PROCEDURE "iCASE".
181
182 There could be a backwards compatibility issue when the StoredProcName was entered
183 manually at design time. That is not selected from the drop down list. If the
184 StoredProcName is entered in mixed case and the procedure was declared e.g. as
185 CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
186 ensure that the value of the StoredProcName is all upper case, unless it was
187 declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
188 quotes).
189
190 Note that when a stored procedure name was declared delimited in double quotes,
191 as in the first example above, the value of the StoredProcName property must not
192 include the delimiters (double quotes).
193
194 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
195 upgrade.conf was not found. This replaces silently ignoring the problem.
196
197 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
198 'Version.%.3d' and is used to generate the section header names (for a given
199 version no.) in the upgrade.conf file.
200
201 IBX Change Log version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
202
203 1. -c command line option added to fbsql example program. Used to set connection
204 character set.
205
206 IBX Change Log version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
207
208 1. Firebird 4 support added.
209
210 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
211 extended precision NUMERIC fields are supported.
212
213 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
214
215 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
216 and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
217
218 5. IBExtract now supports FB4 enhancements:
219 - new data types as above
220 - Identity column extensions
221 - Default user role
222 - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
223 - Internal Functions
224
225 6. IBExtract: new event: OnExtractLines.
226
227 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
228
229 8. IBXServices: Server version no. parsing now allows any letter before major version number
230 and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
231
232 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
233 format for rendering a time zone.
234
235 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
236 to convert TIME WITH TIME ZONE data type values to and from GMT.
237
238 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
239 IIBGUIInterface and IIBTimerInf respectively.
240
241 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
242 now accessible as properties of TIBDatabase and TIBTransaction respectively.
243
244 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
245 truncated to its fixed character width rather than being right padded with
246 white space to the maximum data size.
247
248 14. TIBTable.Empty table. In additional to deleting all records in the underlying
249 table, the internal buffers are now also flushed ensuring that the TIBTable is
250 also empty.
251
252 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
253
254 16. TIBXControlService descendents: DatabaseName may now be set using a database
255 connect string. The database name is extracted from the connect string.
256
257 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
258
259 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
260
261 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
262 not being present as required.
263
264 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
265 version that can be customised to work with other database drivers.
266
267 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
268 unnecessary CR at end of line on Unix platforms.
269
270 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
271 seconds in order to reduce risk of message loss.
272
273 23. ISQLMonitor: read and write count statistics now available via:
274 property TIBSQLMonitor.ReadCount;
275 IIBSQLMonitorHook.GetWriteCount: integer;
276
277 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
278
279 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
280
281 1. TIBStringField: when a string value is read from a dataset buffer, if the
282 number of UTF8 characters exceeds the string size then string is truncated
283 to the maximum string size. This is usually a problem with fixed width columns
284 right padded with white space.
285
286 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
287 If SQLFiltered is set then when a dataset is opened, each line in the
288 SQLFilterParams property is assumed to be a SQL condition clause and
289 ANDed into the Where clause of the SQL Select statement provided as a
290 dataset property. Each such SQL condition thus acts as an additional filter
291 on the dataset.
292
293 3. The Filtered property inherited from TDataset is no longer used for SQL (server
294 side filters).
295
296 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
297 text matches complete entry.
298
299 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
300 dataset are active (avoids risk of access violation if master is inactive)
301
302 6. TIBEvents: Registered property can now be set at design time even if database not open
303
304 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
305 This should prevent "spillover" of events between sessions.
306
307 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
308 This should ensure that the internal buffer is set up correctly and avoids
309 a duplicate initial row.
310
311 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
312 That is, the DataSize should be the field size * character set width. The
313 value returned by DataSize is now the same as the Dataset buffer size reserved
314 for the field.
315
316 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
317
318 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
319 and vice-versa. This may result in an exception being raised (correctly) for
320 older programs when using dataset fields added to a form and the database has been
321 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
322 In such cases, the field needs to be deleted in the IDE fields editor and then
323 added back in.
324
325 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
326 false if query contains only white space and not just empty.
327
328 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
329 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
330 is cancelled.
331
332 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
333 called on a null field.
334
335 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
336 results in an empty dataTC86 Client side Filtered Dataset 1 X
337 set.
338
339 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
340 a cached update is applied and an exception is raised.
341
342 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
343
344 17. Console Mode Local Database support: backup/restore should now work correctly.
345
346 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
347 possible and an exception raised.
348
349 19. MinimumVersionNo added to Local Database Support. Database will not open if
350 below this version no. and upgrade not possible.
351
352 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
353
354 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
355 not SQL Identifiers are now supported.
356
357 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
358 passed to the Firebird engine for execution.
359
360 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
361 is made to scroll back.
362
363 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
364
365 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
366 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
367
368 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
369 validated. If no match is found in the list of field names and the database has
370 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
371 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
372
373 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
374 with fpc 3.2.
375
376 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
377
378
379 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
380 and is used to override the default settings in the client side "firebird.conf" This
381 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
382 Each line of the string list should be a setting in the same format as "firebird.conf".
383 For example "WireCompression = true" in order to request wire compression on the client side.
384
385 Note: explicit settings in the client side "firebird.conf" appear to take precedence
386 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
387 also require a compatible setting in the server side "firebird.conf". For example
388 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
389 compression to be used.
390
391 Whether or not WireCompression or WireCrypt are in use can be checked using the information
392 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
393 ibx/examples/dbinfo for examples of how to display this information.
394
395 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
396 is a "convenience" property. If set the "WireCompression=true" is added to the
397 ConfigOverrides. If unchecked then this setting is removed.
398
399 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
400 not "INT64".
401
402 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
403 These are:
404 property TimestampFormat: string;
405 property DateFormat: string;
406 property TimeFormat: string;
407
408 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
409 DATETIME and TIME. The format strings use the standard FPC date/time format
410 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
411
412 If any of the above properties are set to an empty string, then the locale default
413 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
414 locale default is extended by appending '.zzz' to include milliseconds.
415
416 TIBCSVDataOut by default sets these properties to the empty string, while the other
417 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
418
419 5. New published property for TIBCSVDataOut:
420 property QuoteStrings: boolean (default true)
421
422 If false then strings are unquoted, otherwise, the QuoteChar property value is
423 used to delimit each and every string in the output.
424
425 6. New published properties for TIBCSVDataOut:
426 property FieldSeparator: string;
427 property HeaderSeparator: string;
428
429 Respectively, these provide the separator character(s) used to separate fields
430 in data and header rows. Both default to ','.
431
432 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
433 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
434 property OnFormatTextString;
435
436 This event handler can be used to process text strings before they are included
437 in the output e.g. to replace unprintable characters with alternative strings.
438 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
439
440 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
441 Uses "FindParam" if in order to find out if a parameter with a given name exists
442 and without raising and exception if it does not.
443
444 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
445 consistency with SQL queries.
446
447 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
448 When true, SQL statement parameter names are parsed case sensitive. Note for
449 TIBDataSet only applies to Select query.
450
451 11. IBEvents: removing a TIBEvent component from a form should no longer result in
452 an IDE exception.
453
454 12. LocalDBSupport: initial database creation should now work correctly
455 when the schema source is an sql file.
456
457 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
458 when defined, this handler will be called by the internal TIBXScript during
459 initial database creation when the schema source is an sql file and may be used
460 to provide a visual indication of progress in console mode.
461
462 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
463 to true while a new local database is being created and its schema populated.
464 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
465 when the database is disconnected/connected during the create DB procedure.
466
467 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
468 are now always ignored and replaced by the user name and password provided as
469 the login parameters for the TIBDatabase referenced from the TIBXScript. The
470 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
471 completely ignored if this property is true.
472
473 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
474 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
475 ImageIndex and SelectImageIndex values on AddNode.
476
477 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
478 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
479 the same database connection.
480
481 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
482 if provided, this should be an conditional SQL expression suitable for
483 including in an SQL Select statement "where" clause. If non-empty and the
484 "Filtered" property is true then the SQL expression provided as the value of
485 the "Filter" property is "ANDed" with any existing condition statement
486 in the SQL statement's "Where" clause.
487
488 If the "Filter" property is set at run time, the "Filtered" property is true
489 and the dataset is already open, then the dataset is closed and re-opened automatically.
490
491 The "Filter" condition may include IBX style parameters. In which case, their
492 value must be set by the dataset's "OnBeforeOpen" event handler.
493
494 This is a public property for TIBDataSet and TIBQuery query and intended for
495 use at run time.
496
497 Note: The property is a published property of TIBTable. The TIBTable functionality
498 is unaffected by this change.
499
500 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
501
502 1. Remove need to check for IsMultiThread by providing access to GUI timers via
503 IBGUIInterface. Note: master/detail delay timer does not apply to console
504 mode apps.
505
506 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
507 statement. This avoids problems if "Execute Block" is used as the Query.
508
509 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
510 internal SQL tokeniser routines.
511
512 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
513 as a select statement, with or without CTEs.
514
515 5. IBSQLParser: parser now recognises the "ROWS" clause.
516
517 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
518 internal SQL tokeniser routines.
519
520 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
521 being raised for valid set statements processed by a data formatter.
522
523 8. New published property for TIBDatabase and TIBXServicesConnection. This is
524 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
525 the path of the Firebird Library used by the database/services connection.
526
527 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
528 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
529 services connection.
530
531 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
532 or param name is not a valid SQL identifier.
533
534 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
535 view of whether the text box should be editable when no DataSource is specified.
536 TIBLookupComboEditBox has been updated to workaround this problem. As long as
537 ReadOnly is false, the text box is editable when no DataSource is specified.
538
539 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
540 the FBLIB environment variable. If you do not want to permit this then you
541 must modify the Register procedure in the design/IBDBReg.pas unit to remove
542 this setting.
543
544 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
545
546 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
547 Utf8EscapeControlChars
548
549 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
550
551 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
552 all previous copies of the IBX source code tree before installing this release.
553
554 The IBX packages used by most users have not changed, with one exception. The
555 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
556 to use the IBServices unit in your applications, please add the iblegacyServices
557 to the list of dependencies. To do this, open the Project Inspector and select
558 Add->New Requirement and select "ibLegacyServices" from the list of available
559 packages.
560
561 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
562 the IBServices unit providing what is intended to be a clearer and easier to
563 use set of IB Services components. See Chapter 10 of the IBX User Guide for
564 more information and the guide to "Firebird Service Management Using IBX".
565 As indicated above, the legacy services components are still available and
566 provided in a separate package. There is no need to update working applications
567 using the older versions except for an additional package dependency.
568
569 2. The IBX packages and source code tree have been re-organised in an attempt to
570 finally get rid of the "duplicate ppu" warnings. This re-organisation should
571 not affect existing users. Section 2.3 of the IBX User Guide describes the
572 new set of IBX packages.
573
574 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
575 updated to use the new Services API components.
576
577 4. The iblocal package has been updated to use the new Services API components.
578
579 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
580 TIBXSecurityService. It had been wrongly classified in the previous version
581 as a per database configuration item. It is global to a server and hence
582 correctly positioned as part of the Security Package. In the DBAdmin example,
583 the setting has moved to the mappings page.
584
585 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
586 are ignored.
587
588 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
589 closed before the database is dropped. Before and After Disconnect event handlers
590 are also fired.
591
592 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
593 is started and not just the first time.
594
595 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
596 depenendency with comp type.
597
598 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
599
600 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
601 then this is recognised and not ignored.
602
603 12. TIBDataSet, TIBQuery, TIBTable: additions:
604 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
605 function GetPerfStatistics(var stats: TPerfCounters): boolean;
606 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
607
608 GetRowsAffected returns the affected row counts from the last insert/update/delete
609 if EnableStatistics = true then GetPerfStatistics returns the current stats
610 counters for the select query. Note: stats accumulate after each fetch from
611 the database. To get total query cost after open, call the "Last" method
612 and then GetPerfStatistics.
613
614 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
615
616 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
617 in parenthesises.
618
619 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
620 SQL identifiers are always delimited by double quotes. If false, then they are
621 only delimited if the identifier is a reserved word, contains lower case or special
622 characters. Set this property to true to retain previous behaviour.
623
624 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
625 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
626
627 16. TIBDataSet, TIBQuery, TIBTable: addition:
628 property MasterDetailDelay: integer {defaults to zero}
629
630 When non-zero and the dataset is a detail table referencing a master table
631 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
632 then a synchronisation delay is added (in milliseconds) between the master
633 row changing and the detail dataset being re-opened. If the master dataset
634 is scrolled before the delay expires then the delay is reset. This can be used
635 to avoid performance overheads when scrolling through a large master dataset.
636
637 Note: uses fptimer and hence requires a thread manager. Under Linux the
638 chreads unit must be included in your project. TTimer is not used in order
639 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
640
641 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
642 with Extract Option eoDatabase.
643
644 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
645 When a deLayoutChanged event is reported on the ListSource dataset, the
646 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
647 relationship with the control's datasource (master).
648
649 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
650
651 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
652 stubs. Pedantic fix really, as procedures output in dependency order anyway.
653
654 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
655 DDL (Firebird 3 and later only).
656
657 22. TIBLookupComboBox Autocomplete Fixes:
658 i. Only appended text is now selected after autocomplete.
659 ii. Uppercase keys no longer ignored for autocomplete.
660 iii. Retain Prefix case is now honoured correctly.
661 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
662 before autocomplete performed. i.e. behaviour now the same as when
663 no DataSource assigned.
664
665 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
666 between SQL statements.
667
668 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
669 ObjectNames are converted to upper case before matching against metadata object
670 names, unless the objectname is delimited by double quotes, in which case, the
671 double quotes are removed and the remaining string is used (unmodified) to match
672 against the metadata object name.
673
674 If true then the ObjectName is used as is without modification and matched
675 against the metadata object name. No attempt is made to remove double quotes.
676
677 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
678 with eoTrigger, these extract types can be used to select only Database Triggers,
679 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
680
681 26. TIBXScript: If an exception occurs during the processing of a statement, the
682 statement separate character is now reset to the default (';').
683
684 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
685
686 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
687 a commit or reconnect statement and instead activated only when next SQL statement
688 is executed.
689
690 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
691
692 30. TIBXScript: case insensitive regex now used when matching statements instead of
693 converting statement to upper case.
694
695 31. TIBExtract: metadata comments now supported. New published property
696 IncludeMetaDataComments (default true). If true then metadata comments included
697 in extracted DDL. New Extract Object member eoComments. This may be used with
698 ExtractObject method to list all metadata comments.
699
700 32. TIBExtract: ListObjectNames method added.
701
702 33. Updated Database component editor to support additional connection string
703 types.
704
705 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
706
707 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
708 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
709 RELEASE.
710
711 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
712
713 1. IBExtract: Identity columns - add additional check for null column for generator name.
714
715 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
716 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
717 information). However, this is also a very useful mechanism for returning updated computed by
718 column values. Values returned as a result of executing an Insert or Update statement
719 replace existing values in the current row for each corresponding column.
720
721 Previously, if a dataset's select query included read only (computed by) fields then
722 an automatic row refresh was performed after an insert or update query had been processed,
723 irrespective of the setting of the "ForcedUpdates" property. This has changed such
724 that an automatic refresh is no longer performed if an insert or update query contains
725 a returning clause that updates one or more fields on the current row. A full row
726 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
727 field values and the select query contains read only fields. Use of Insert/update
728 returning should be significantly more efficient than executing a refresh query.
729
730 This behaviour change is intended to be backwards compatible and there should be no need to change
731 existing programs, other than to improve performance by using the new capability.
732
733 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
734 they are called when the dataset row is being deleted, there is no value in
735 updating the current record from the query result. Instead, a new event handler
736 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
737 an OnDeleteReturning event handler is provided then it is called with the IResults returned
738 by the query. The event handler can then interrogate the query results and
739 perform whatever action is necessary. For example to confirm, to the user,
740 the deletion of a row with the returned values.
741
742 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
743 any Computed By or Identity Columns. The IBTables example has been updated to
744 illustrate the computation of the employee Full Name on update.
745
746 5. TIBTable: The GeneratorField property is now published.
747
748 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
749 When InsertSQL is generated, the Identity columns are not included in the list of values to
750 be inserted. A RETURNING clause is added to the insert statement to return the value of
751 each Identity column after the insert is executed.
752
753 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
754 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
755 Insert..Returning clause.
756
757 8. TIBGenerator: small performance improvement by not preparing query each time
758 a new value is generated.
759
760 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
761
762 10. Property editors will now sync table name to a System Table when "Include System
763 Tables" is selected and the query is for a System Table.
764
765 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
766 values are no longer converted to milliseconds from TDateTime and then back again
767 to TDateTime (the conversion to milliseconds is the default TDataset approach).
768
769 12. Property Editors handling of Stored Procedures.
770 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
771 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
772 query).
773 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
774
775 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
776 can be used to select a package. If non-empty, the stored procedure name is
777 expected to be a stored procedure defined in the specified package and the
778 generated SQL will be as required for a stored procedure located in a package.
779
780 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
781 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
782 which a stored procedure can be selected. With no package name selected, non-package
783 stored procedures are listed.
784
785 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
786 for password on reconnect.
787
788 16. TIBDatabase: use IAttachment for connection default character set id, code page
789 and character set name.
790
791 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
792 DB info lookups"
793
794 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
795
796 19. Add a property Editor for TIBUpdate.RefreshSQL.
797
798 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
799 parameters. This stops an exception being raised when the field cannot be
800 located in the record buffer.
801
802 21. Property Editors now automatically include System Tables when opened and when the query table
803 is a System Table.
804
805 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
806 This avoids errors due to a stale SQRB or SRB being used for the next query.
807
808 23. IBServices: Service attach parameters now include "expected_db". This is used to
809 add the SPB item isc_spb_expected_db. This names a database using
810 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
811 database. examples/services re-written to illustrate use of "expected_db".
812
813 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
814 This avoids truncated backups when the server returns a timeout (busy) response.
815
816 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
817
818 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
819 databasenames. These are respectively expanded to the local system's temp directory
820 (including trailing delimiter) or to a prescribed data directory (including
821 trailing delimiter). Under Unix systems the data directory is a hidden directory
822 in the user's home directory. The hidden directory name is either the string returned
823 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
824 Under Windows, the directory is the same as the Data Directory as decribed
825 above but instead prefixed by the User's application data path. These may be
826 used to improve application portability for Personal Databases.
827
828 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
829 this has not worked for a long time and is not useful either. FieldDefs should be
830 managed using the Fields Editor as with any other dataset. To access the fields
831 editor for a TIBTable component, double click on the component. The fields editor
832 is then displayed.
833
834 28. TIBDatabaseInfo: new properties/function
835 * DateDBCreated (returns date/time database created)
836 * TransactionCount (returns no. of active transactions)
837 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
838 * PagesFree (Firebird 3 or later)
839 * PagesUsed (Firebird 3 or later)
840 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
841 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
842
843 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
844
845 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
846
847 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
848 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
849
850 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
851 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
852 firing during backup and restore.
853
854 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
855 for verbose output using the new property "StatisticsRequested".
856 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
857
858 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
859
860 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
861 palette. This uses the online validation feature added in Firebird 2.5. The
862 services's properties enable inclusion/exclusion of tables and indexes using
863 regular expressions. See.
864 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
865
866 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
867 option on a database.
868
869 37. TIBCustomService: Assign method implemented to allow copying of service login
870 context between service API components. "Detach" method now only detaches
871 service when last reference to the service interface detaches. Tidy up of
872 code for SetActive and Attach methods including password hiding.
873
874 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
875 and used to determine the auth method and protocol used for the connection.
876
877 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
878 a Create Database Statement generated by IBX.
879
880 40. All IBServices now have an additional published property "PortNo". This may
881 be set to a non-standard port number when necessary. If zero then the default
882 port number is used.
883
884 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
885 and not just the mouse.
886
887 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
888
889 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
890 image index and selected image index for each node to be set from a database field.
891
892 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
893 then database schema includes grants to all users. If not present then the
894 only user grants included are those to User PUBLIC.
895
896 45. TIBTreeView: performance improvement. When expanding include both expanded node
897 and child nodes in dataset.
898
899
900 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
901
902 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
903 changes.
904
905 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
906 Bug could result in truncated multi-byte character set values.
907
908 3. Changes consequential on moving fbintf character set utility functions from
909 IFirebirdAPI to IAttachment.
910
911 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
912
913 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
914 results in autocomplete ignoring prefix text.
915
916 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
917 entering a new name into the text box.
918
919 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
920 Firebird rather than recomputing it.
921
922 8. Property Editor positioning tidy up: All IBX Property editors should now be
923 screen centre. Previously some were "poDesigned" which may be inappropriate
924 for multi monitor desktops.
925
926 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
927
928 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
929 a transaction and always reset the object.
930
931 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
932
933 13. TIBXScript: Allow for override of database filename in Create Database statements.
934
935 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
936 to a gbak format archive.
937
938 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
939
940 16. IBLocaldb: Drop database if error creating an empty database.
941
942 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
943 unless selected node not in current dataset.
944
945 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
946 to TIBCustomService, and IBlocalDB code tidy up.
947
948 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
949 behaviour due to uninitialised variable.
950
951 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
952 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
953
954 21. IBSQL: When Database changed ensure that all resources are freed.
955
956 22. IBCustomDataset: When database changed ensure that queries an unprepared.
957
958 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
959 * Line Wrap on SQL Token boundaries (on user command)
960 * auto-complete table names in drop down list of table names
961 * Double click on tablename or field name adds to SQL text
962
963 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
964
965 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
966 TVariantArray. Seems to avoid memory corruption in Windows (probably a
967 workaround for a problem in fpc 3.0.4 win64).
968
969 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
970
971 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
972
973 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
974
975 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
976 include remote system name.
977
978 2. TIBExtract: No longer include comment header and COMMIT statement for empty
979 tables when data included in output.
980
981 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
982 and timing information to be written to stdout. This may be used to locate
983 performance bottlenecks.
984
985 4. SQLParser: only call "OnChanging" event handler when value is different.
986
987 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
988
989 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
990 that BindFields is called when the query is next activated. Avoids FieldName
991 not found error.
992
993 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
994 purpose and allows the programmer to define any action they want for Update, Insert
995 or Delete. This may be complex SQL (similar to a Trigger), application specific
996 filtering of updates, or use of statements such as Grant or Revoke instead of
997 normal DML. See User Manual for more information.
998
999 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
1000
1001 1. TIBEvents: Fix uninitialised variable that could result in lost events.
1002
1003 2. TIBExtract: Added support for FB3 "USAGE" privilege.
1004
1005 3. TIBExtract: data formatted as Charset set "octets" is now output using
1006 hexadecimal notation.
1007
1008 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
1009 using a simple XML format.
1010
1011 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
1012 grants to these objects.
1013
1014 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
1015 dependency problems restoring complex databases.
1016
1017 7. TIBXScript: This component has been restructured to allow for the processing of
1018 embedded XML in INSERT statements and to support interactive sources in addition
1019 to non-interactive data sources such as files.
1020
1021 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
1022
1023 9. TIBXScript: ISQL compatiable Set statements are now supported:
1024 SET SQL DIALECT
1025 SET TERM
1026 SET AUTODDL
1027 SET BAIL
1028 SET ECHO
1029 SET COUNT
1030 SET STATS
1031 SET NAMES <character set>
1032
1033 10. IBVersion unit added to hold current IBX Version Number information.
1034
1035 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
1036 and domain definitions.
1037
1038 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
1039 fully supported.
1040
1041 13. TIBExtract: when a database dump includes data, the generator values are now also set.
1042
1043 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
1044
1045 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
1046
1047 See also doc/IBX4LazarusGuide.pdf for important information on
1048 upgrading to IBX2.
1049
1050 1. Size property of TIBStringField is now the width in characters of the field
1051 and not the byte length. This applies only to multi-byte character sets such
1052 as UTF8. The original approach aligned with TStringField. However, the TStringField
1053 code is not recognised as a bug and hence this change to align the behaviour.
1054 The TStringField change is expected in fpc 3.2.0.
1055
1056 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
1057 true (default) then Size property value saved in the lfm is ignored. Size is
1058 always set from the dynamic information read from the database. It is unclear
1059 why anyone would want to override this and set Size to false.
1060
1061 3. ibxscript: should now handle correctly a Case..End statement within a procedure
1062 block.
1063
1064 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
1065 exist when an attempt is made to connect to it (run time only) then an attempt
1066 is made to create the database.
1067
1068 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
1069 has been successfully created as a result of a call to CreateDatabase or when
1070 creating a database after it was found not to exist.
1071
1072 6. DBControlGrid: a race condition could result in the wrong row image being
1073 written to the cache. This has been avoided by a trip round the message
1074 loop before rendering the row image.
1075
1076 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
1077 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
1078 known to risk corrupt rendering of row images when the control is first
1079 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
1080 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
1081
1082 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
1083 a TDateEdit control located on an editor panel.
1084
1085 9. TIBExtract: brought up-to-date plus many bug fixes.
1086
1087 10. DBControlGrid: Removed memory leak when updating rows.
1088
1089 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
1090
1091 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
1092
1093 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
1094 when target codepage is CP_NONE. This is a workaround for
1095 http://bugs.freepascal.org/view.php?id=30622.
1096
1097 2. DBLog option removed from TIBStatisticalService - not supported by server
1098 since Firebird 1.5.
1099
1100 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1101 similar.
1102
1103 4. IBCodePage: updated mapping between codepages and character id.
1104
1105 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1106 Firebird. Character sets with a char width of two are not UTF16.
1107
1108 6. Strings received from the database are now always transliterated into UTF8
1109 regardless of the database character set or connection character set. This
1110 is for compatibility with the LCL.
1111
1112 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
1113
1114 1. IBBlob: Defer reading of blob until read method called. This avoids having to
1115 read in an entire blob just to get the size of the blob. General performance
1116 improvement when opening datasets containing blobs.
1117
1118 2. Clearing a Blob now sets the corresponding field's modified flag.
1119
1120 3. IBLookupCombo: When not performing auto-complete, original query sort order
1121 is now used.
1122
1123 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1124 determined.
1125
1126 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1127
1128 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1129 lazarus 1.6.0
1130
1131 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
1132 compilation error.
1133
1134 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
1135
1136 1. No character set specified for connection: when a text blob is retrieved, the
1137 character set is determined by looking up the native character set using then
1138 Firebird API. Otherwise a text mode blob is assumed to have the same character
1139 set as the connection.
1140
1141 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1142 for Login Dialog returing a change to the database path.
1143
1144 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1145 to be changed from that given in the TIBDatabase/TIBServer component and for the
1146 entered value to be saved on a project specific basis (design time only).
1147
1148 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1149 column fieldname. If they are the same then it is acts as a look up for the KeyValue
1150 Otherwise, it sets the column text to the selected ListField Value.
1151
1152 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1153 column width.
1154
1155 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1156 and a case insensitive search is requested.
1157
1158 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1159 or column ListSource.
1160
1161 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1162 unprepare) when closing and the text has not changed.
1163
1164 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1165 Less likely to cause a cursor re-use error on Windows.
1166
1167 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1168 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1169
1170 11. TIBTreeView: Guard against nil destination on record changed
1171
1172 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1173 string type with the code page set to reflect the returned field encoding after
1174 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
1175 earlier versions.
1176
1177 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1178 will now result in transliteration to the code page specified for the Firebird driver
1179 if the assigned string has a different code page. FPC 3.0.0 onwards only.
1180
1181 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1182 is ignored and the lc_ctype value, when the database is opened, is set to align with
1183 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1184 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1185 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1186 the GETACP is used to determine the Windows code page.
1187
1188 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1189 name used as the lc_ctype when the database was opened. Only valid while the
1190 Database is connected.
1191
1192 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1193 id that corresponds to the DefaultCharSetName.
1194
1195 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1196
1197 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1198 path is given and database attach fails due to access permission issues on the
1199 temp directory or security database, then the attach is retried with "localhost:"
1200 prefixing the databasename. This should avoid problems when the database has to
1201 be accessed by a local (e.g. classic) server and libfbembed is used.
1202
1203 2. Windows: revised search order for Firebird DLL:
1204 i. The Firebird Embedded Server in the application Directory.
1205 ii. If the FIREBIRD environment variable is set then the directory this
1206 points to is searched for the FB Client DLL and then then underlying
1207 "bin" directory.
1208 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1209 is used to locate the Firebird installation directory and the underlying
1210 "bin" directory is searched for the FB Client DLL.
1211 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1212 are searched for the FB Client DLL.
1213 v. The PATH Environment variable is used to search for the FB Client DLL.
1214 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1215
1216 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1217 See doc/readme.scriptengine and example applications.
1218
1219 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1220 simplify the use of the embedded firebird server on both Linux and Windows platforms.
1221 See dpc/readme.localdatabase and example applications.
1222
1223 5. IBDynamicGrid: Reordering on column header click should now also work for
1224 dynamic columns.
1225
1226 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1227 between incrementing/decrementing the lock count and signalling the event.
1228
1229 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1230
1231 1.3.2 was never formally released and only made available as beta copies.
1232
1233 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1234
1235 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1236
1237 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1238
1239 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1240 i.e. when it is a calculated field
1241
1242 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1243 This problem was due to a race condition between recalculating row heights and
1244 determining which row was selected by the mouse click. The row height calculation
1245 is now deferred by an extra trip round the message loop allowing the row to
1246 be always calculated on the current grid layout rather than risking it being
1247 calculated on the grid layout after the expanded row has been shrunk.
1248
1249 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1250 Windows.
1251
1252 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1253 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1254 to be determined at runtime. See doc/readme.charactersets.html.
1255
1256 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1257 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1258
1259 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1260 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1261 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1262
1263 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1264 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1265 implies no truncation.
1266
1267 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1268
1269 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1270 (avoids "Not in Edit Mode" error).
1271
1272 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1273
1274 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1275 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1276
1277 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1278
1279 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1280
1281 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1282
1283 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1284
1285 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1286
1287 1. OnCloseUp Event Handler added to TDBLookupProperties
1288
1289 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1290 problem with row size when exception is called.
1291
1292 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1293
1294 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1295 in a TCustomComboBox and ignores return key if in a TCustomMemo
1296
1297 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1298 keyed in i.e. when autocomplete not performed
1299
1300 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1301 console mode applications with all LCL required functions (builtin dialogs and
1302 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1303 not included in your project, IBX should compile and link with a console mode program.
1304 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1305 console mode application or the IDE will automatically assume that your
1306 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1307
1308 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1309 to use the built in dialogs and cursor management. IBDialogs is
1310 included by default if "ibexpress" is in your project source's "uses" clause.
1311 This should be the case for all projects created through the IDE. This is why
1312 you do not want to add the ibexpress package to console mode applications. The
1313 ibexpressconsolemode package has been created to allow console mode programs
1314 to avoid adding LCL dependencies when using IBX, while still having the
1315 unit search paths set up correctly.
1316
1317 Existing users should check to ensure that the "ibexpress" unit is included in
1318 each project's source file (*.lpr).
1319
1320 You may find that in order for the IDE to recognise that ibexpressconsolemode
1321 exists, you have to first open the package in the IDE and then close it. This
1322 adds it to the most recently accessed packages list. To make it permanently
1323 available, add the package name to lazarus' staticpackages.inc file.
1324
1325 Thanks to Julio Jiménez for suggesting support of console mode.
1326
1327 7. SQL Parser can now accept quoted strings that include new lines
1328
1329 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1330 of text on start of edit. This is particularly useful when tabbing to a
1331 column and then inserting text.
1332
1333 9. New Examples provided for IB Services and ISQLMonitor.
1334
1335 10. Fix error when writing to blob streams that recorded only the last buffer
1336 write in the blob stream. In most cases, this did not cause a problem as the
1337 IB Blob Stream is written in a single write. However, with the TDBImage, write
1338 of a graphic type prefix was lost which caused a problem when the image could
1339 not be automatically recognised.
1340
1341 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1342 already open" errors due to random numbers used for the cursor name being identical.
1343
1344 12. IBTable: corrected error that could result in an "Index out of bounds" error
1345 when opening the table and the Primary Key is the last or only column in the
1346 table. Thanks to Rick Hoover for the fix.
1347
1348 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1349 of "UTF-8", and update list of available database character sets. Existing
1350 users should check the current lc_ctype setting in their applications.
1351
1352 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1353
1354 1. Firebird Services: avoid List Index error when opening a service with an
1355 empty Params property.
1356
1357 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1358 Link now set up in Loaded method - avoids occasional failure to apply
1359 SQL markup on initial open.
1360
1361 3. "Employees" example performance improvements when scrolling.
1362
1363 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1364 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1365 random image cached).
1366
1367 5. DBControlGrid: Should now react to changes in panel height at run time.
1368
1369 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1370 even when further rows exist.
1371
1372 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1373 always be derived from panel height and setting this property can cause confusion.
1374 Note for existing projects: to avoid a missing property error at run time,
1375 each form using the DBControlGrid must be opened, updated and saved in the IDE
1376 in order to remove the property value from the lfm.

1379 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1380
1381 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1382 call Prepare before setting parameter values.
1383
1384 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1385
1386 3. Code tidyup and more robust handling of dsql information result vector.
1387
1388 4. Support for centralised handling of transaction status changes. TIBTransaction
1389 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1390 and "AfterExecQuery". The first three are called after the same event is called
1391 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1392 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1393 enable monitoring of transaction status changes for a given transaction to be
1394 handled in a single place. For example, when a change to the dataset occurs
1395 an indicator can be set that shows the user that in order to save changes,
1396 the transaction should be committed. Rather than doing this per dataset, this
1397 can now be done per transaction.
1398
1399 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1400 the dataset is scrolled. However, any changes to the current row are, by default,
1401 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1402 have a new property "DataSetCloseAction" that adds automatic posting of changes
1403 on dataset close. If this property is set to dcDiscardChanges (default) then the
1404 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1405 then IBX will attempt to post any unsaved changes before the dataset is closed
1406 (and after the BeforeClose event handler is called). The exception is when the
1407 dataset is being closed as a result of a transaction rollback. In this case,
1408 no action is taken and any unsaved changes are discarded. This avoids both
1409 unnecessary overhead and the risk that a validation error may occur in the Post
1410 raising an exception and thereby preventing a rollback.
1411
1412 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1413 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1414 width. Display Widths are now corrected by dividing by the max byte width per character.
1415 For UTF8 character sets, the byte width is four and hence the Display Width will be
1416 the byte width divided by 4. The byte width of each character set is determined
1417 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1418 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1419
1420 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1421
1422 8. IBLookupComboEditBox: List should now always be restored to full list when the
1423 control loses focus. Default Key press default interval reduced to 200ms.
1424
1425 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1426 when dataset rows are less than visible rows.
1427
1428 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1429 does not exist or DataSet is empty. More responsive on dataset open. New event
1430 OnRestorePosition. Column sort disabled if no header row.
1431
1432 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1433 while dataset state is dsInsert. Avoids posting errors.
1434
1435 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1436 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1437
1438 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1439
1440 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1441 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1442 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1443 always "posts" the current record regardless or whether or not it may be more appropriate
1444 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1445 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1446 as the first action of the "Post" method and allows the handler to convert the Post
1447 into a Cancel if that is the appropriate action on moving to a different row. This is
1448 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1449 raised here, but it may still be more appropriate to validate a post and signal
1450 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1451
1452 15. On Unix derived systems, the Firebird library name can now be given as a colon
1453 separated list. Each library name on the list is tried in turn, in left to right
1454 order with the first found being used as the firebird library. By default, on Linux,
1455 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1456 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1457
1458 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1459 then it will still attempt to access the database via the Firebird Server and will
1460 require a username and password. If only the pathname is given, then the username
1461 and password should be omitted and the unix file permissions are used to grant
1462 access.
1463
1464 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1465
1466 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1467 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1468 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1469 corresponds to a row of the linked DataSource. Any data aware control on the
1470 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1471
1472 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1473 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1474 takes place during database access. This may be useful when there are performance issues with
1475 the change of cursor. Setting the property to false suppresses the change of cursor.
1476
1477 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1478 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1479 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1480 making all changes permanent immediately rather than when the transaction is explicitly
1481 committed.
1482
1483 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1484 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1485
1486 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1487
1488 Development version only.
1489
1490 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1491
1492 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1493 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1494 "Where" and "Having" clauses to implement user specified filters of arbitrary
1495 complexity.
1496
1497 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1498 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1499 These are:
1500
1501 - TIBLookupComboEditBox
1502 - TIBDynamicGrid
1503 - TIBTreeview
1504
1505 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1506 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1507 to revise the available list and restrict it to items that are prefixed by the
1508 typed text (either case sensitive or case insensitive). Autoinsert allows a
1509 newly typed entry to be added to the list dataset and included in the available
1510 list items.
1511
1512 TIBDynamicGrid is a TDBGrid descendent that provides for:
1513 - automatic resizing of selected columns to fill the available row length
1514 - automatic positioning and sizing of a "totals" control, typically at the
1515 column footer, on a per column basis.
1516 - DataSet resorting on header row click, sorting the dataset by the selected column.
1517 A second click on the same header cell reversed the sort order.
1518 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1519 is automatically expanded and a panel superimposed on it. The panel can have any
1520 number of child controls, typically data aware controls with the same datasource
1521 as the grid allowing for editing of additional fields and more complex editors.
1522 - Reselection of the same row following resorting.
1523 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1524 Its properties are specified on a per column basis and allows for one or more
1525 columns to have their values selected from a list provided by a dataset.
1526 Autocomplete and autoinsert are also available. The existing picklist editor
1527 is unaffected by the extension.
1528
1529 TIBTreeView is a data aware TCustomTreeView.
1530
1531 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1532 zero scale will no longer return an error. An Int64 will be returned instead.
1533
1534 4. TIBTransaction now has events for Before and After Transaction End and a new function
1535 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1536
1537 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1538 repeated multiple times.
1539
1540 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1541 check used to get in the way of using Stored Procedures, and "Update or Insert"
1542 statements.
1543
1544 7. Insert, Modify and Delete property Editors now support Query Generation from
1545 Stored Procedures.
1546
1547 8. Three new examples illustrate the use of the new IB Controls
1548
1549
1550 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1551
1552 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1553 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1554 Gabor Boros for reporting this problem and for testing the improvements).
1555
1556 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1557 See readme.field+param.names in the doc folder.
1558
1559 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1560 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1561
1562 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1563
1564 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1565 actions.
1566
1567 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1568 thanks to Yuriy Kopnin for pointing this out).
1569
1570 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1571
1572 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1573 for both fields and parameter setting.
1574
1575 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1576 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1577
1578 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1579 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1580
1581 11. TIBTable now has a property editor for "MasterFields"
1582
1583 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1584 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1585
1586 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1587 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1588

1590 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1591
1592 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1593
1594 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1595
1596 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1597 it is null. This allows for alternative user defined setting of the generator
1598
1599 Many thanks to Julio Jiménez for this fix
1600
1601 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1602 and suggests that the user may have forgotten to install it.
1603
1604 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1605
1606 1. Conditional compilation used to limit registration of TIntegerField to
1607 Lazarus versions less than 1.1
1608
1609 2. When a database connection is created, character set is now by default set
1610 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1611 1250 to 1254.
1612
1613
1614 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1615
1616 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1617
1618
1619 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1620
1621 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1622 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1623
1624 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1625 package is changed to do this (which it should do).
1626
1627 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1628
1629 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1630
1631 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1632
1633 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1634
1635 4. Property editors should now correctly resize.
1636
1637 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1638 (restored original functionality)
1639
1640 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1641 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
