1 IBX Change Log version (2.4-3 Build 12847) Mon, 18 Oct 2021 09:35:36 +0100
2
3 1. Add try-..except check when initially loading library in IDE. This should
4 ensure that IDE continues to load even when a failure occurs in IBX load
5 library.
6
7 2. IBXScript: now recognises a CASE...END block within a stored procedure and
8 hence will correctly detect end of the outer containing block when the block
9 contains a SELECT ... CASE ... END construct.
10
11 3. IBExtract: some further tidying up to remove extraneous white space.
12
13 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
14 errors when extra elements are added to DB.TFieldType.
15
16 5. IBUpdate: updated to reflect changes to ISQLParam.
17
18 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
19
20 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
21
22 IBX Change Log version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
23
24 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
25 exception of those defined to be one byte wide e.g. DBImplementationNo.
26
27 2. TIBSQL: Batch Update/Insert support added.
28
29 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
30 is no longer automatically converted to upper case when it is syntactically a
31 SQL Identifier. This is to support the use of stored procedures defined e.g.
32 as CREATE PROCEDURE "iCASE".
33
34 There could be a backwards compatibility issue when the StoredProcName was entered
35 manually at design time. That is not selected from the drop down list. If the
36 StoredProcName is entered in mixed case and the procedure was declared e.g. as
37 CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
38 ensure that the value of the StoredProcName is all upper case, unless it was
39 declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
40 quotes).
41
42 Note that when a stored procedure name was declared delimited in double quotes,
43 as in the first example above, the value of the StoredProcName property must not
44 include the delimiters (double quotes).
45
46 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
47 upgrade.conf was not found. This replaces silently ignoring the problem.
48
49 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
50 'Version.%.3d' and is used to generate the section header names (for a given
51 version no.) in the upgrade.conf file.
52
53 IBX Change Log version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
54
55 1. -c command line option added to fbsql example program. Used to set connection
56 character set.
57
58 IBX Change Log version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
59
60 1. Firebird 4 support added.
61
62 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
63 extended precision NUMERIC fields are supported.
64
65 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
66
67 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
68 and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
69
70 5. IBExtract now supports FB4 enhancements:
71 - new data types as above
72 - Identity column extensions
73 - Default user role
74 - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
75 - Internal Functions
76
77 6. IBExtract: new event: OnExtractLines.
78
79 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
80
81 8. IBXServices: Server version no. parsing now allows any letter before major version number
82 and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
83
84 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
85 format for rendering a time zone.
86
87 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
88 to convert TIME WITH TIME ZONE data type values to and from GMT.
89
90 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
91 IIBGUIInterface and IIBTimerInf respectively.
92
93 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
94 now accessible as properties of TIBDatabase and TIBTransaction respectively.
95
96 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
97 truncated to its fixed character width rather than being right padded with
98 white space to the maximum data size.
99
100 14. TIBTable.Empty table. In additional to deleting all records in the underlying
101 table, the internal buffers are now also flushed ensuring that the TIBTable is
102 also empty.
103
104 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
105
106 16. TIBXControlService descendents: DatabaseName may now be set using a database
107 connect string. The database name is extracted from the connect string.
108
109 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
110
111 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
112
113 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
114 not being present as required.
115
116 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
117 version that can be customised to work with other database drivers.
118
119 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
120 unnecessary CR at end of line on Unix platforms.
121
122 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
123 seconds in order to reduce risk of message loss.
124
125 23. ISQLMonitor: read and write count statistics now available via:
126 property TIBSQLMonitor.ReadCount;
127 IIBSQLMonitorHook.GetWriteCount: integer;
128
129 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
130
131 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
132
133 1. TIBStringField: when a string value is read from a dataset buffer, if the
134 number of UTF8 characters exceeds the string size then string is truncated
135 to the maximum string size. This is usually a problem with fixed width columns
136 right padded with white space.
137
138 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
139 If SQLFiltered is set then when a dataset is opened, each line in the
140 SQLFilterParams property is assumed to be a SQL condition clause and
141 ANDed into the Where clause of the SQL Select statement provided as a
142 dataset property. Each such SQL condition thus acts as an additional filter
143 on the dataset.
144
145 3. The Filtered property inherited from TDataset is no longer used for SQL (server
146 side filters).
147
148 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
149 text matches complete entry.
150
151 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
152 dataset are active (avoids risk of access violation if master is inactive)
153
154 6. TIBEvents: Registered property can now be set at design time even if database not open
155
156 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
157 This should prevent "spillover" of events between sessions.
158
159 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
160 This should ensure that the internal buffer is set up correctly and avoids
161 a duplicate initial row.
162
163 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
164 That is, the DataSize should be the field size * character set width. The
165 value returned by DataSize is now the same as the Dataset buffer size reserved
166 for the field.
167
168 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
169
170 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
171 and vice-versa. This may result in an exception being raised (correctly) for
172 older programs when using dataset fields added to a form and the database has been
173 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
174 In such cases, the field needs to be deleted in the IDE fields editor and then
175 added back in.
176
177 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
178 false if query contains only white space and not just empty.
179
180 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
181 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
182 is cancelled.
183
184 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
185 called on a null field.
186
187 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
188 results in an empty dataTC86 Client side Filtered Dataset 1 X
189 set.
190
191 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
192 a cached update is applied and an exception is raised.
193
194 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
195
196 17. Console Mode Local Database support: backup/restore should now work correctly.
197
198 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
199 possible and an exception raised.
200
201 19. MinimumVersionNo added to Local Database Support. Database will not open if
202 below this version no. and upgrade not possible.
203
204 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
205
206 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
207 not SQL Identifiers are now supported.
208
209 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
210 passed to the Firebird engine for execution.
211
212 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
213 is made to scroll back.
214
215 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
216
217 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
218 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
219
220 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
221 validated. If no match is found in the list of field names and the database has
222 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
223 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
224
225 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
226 with fpc 3.2.
227
228 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
229
230
231 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
232 and is used to override the default settings in the client side "firebird.conf" This
233 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
234 Each line of the string list should be a setting in the same format as "firebird.conf".
235 For example "WireCompression = true" in order to request wire compression on the client side.
236
237 Note: explicit settings in the client side "firebird.conf" appear to take precedence
238 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
239 also require a compatible setting in the server side "firebird.conf". For example
240 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
241 compression to be used.
242
243 Whether or not WireCompression or WireCrypt are in use can be checked using the information
244 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
245 ibx/examples/dbinfo for examples of how to display this information.
246
247 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
248 is a "convenience" property. If set the "WireCompression=true" is added to the
249 ConfigOverrides. If unchecked then this setting is removed.
250
251 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
252 not "INT64".
253
254 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
255 These are:
256 property TimestampFormat: string;
257 property DateFormat: string;
258 property TimeFormat: string;
259
260 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
261 DATETIME and TIME. The format strings use the standard FPC date/time format
262 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
263
264 If any of the above properties are set to an empty string, then the locale default
265 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
266 locale default is extended by appending '.zzz' to include milliseconds.
267
268 TIBCSVDataOut by default sets these properties to the empty string, while the other
269 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
270
271 5. New published property for TIBCSVDataOut:
272 property QuoteStrings: boolean (default true)
273
274 If false then strings are unquoted, otherwise, the QuoteChar property value is
275 used to delimit each and every string in the output.
276
277 6. New published properties for TIBCSVDataOut:
278 property FieldSeparator: string;
279 property HeaderSeparator: string;
280
281 Respectively, these provide the separator character(s) used to separate fields
282 in data and header rows. Both default to ','.
283
284 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
285 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
286 property OnFormatTextString;
287
288 This event handler can be used to process text strings before they are included
289 in the output e.g. to replace unprintable characters with alternative strings.
290 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
291
292 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
293 Uses "FindParam" if in order to find out if a parameter with a given name exists
294 and without raising and exception if it does not.
295
296 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
297 consistency with SQL queries.
298
299 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
300 When true, SQL statement parameter names are parsed case sensitive. Note for
301 TIBDataSet only applies to Select query.
302
303 11. IBEvents: removing a TIBEvent component from a form should no longer result in
304 an IDE exception.
305
306 12. LocalDBSupport: initial database creation should now work correctly
307 when the schema source is an sql file.
308
309 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
310 when defined, this handler will be called by the internal TIBXScript during
311 initial database creation when the schema source is an sql file and may be used
312 to provide a visual indication of progress in console mode.
313
314 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
315 to true while a new local database is being created and its schema populated.
316 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
317 when the database is disconnected/connected during the create DB procedure.
318
319 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
320 are now always ignored and replaced by the user name and password provided as
321 the login parameters for the TIBDatabase referenced from the TIBXScript. The
322 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
323 completely ignored if this property is true.
324
325 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
326 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
327 ImageIndex and SelectImageIndex values on AddNode.
328
329 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
330 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
331 the same database connection.
332
333 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
334 if provided, this should be an conditional SQL expression suitable for
335 including in an SQL Select statement "where" clause. If non-empty and the
336 "Filtered" property is true then the SQL expression provided as the value of
337 the "Filter" property is "ANDed" with any existing condition statement
338 in the SQL statement's "Where" clause.
339
340 If the "Filter" property is set at run time, the "Filtered" property is true
341 and the dataset is already open, then the dataset is closed and re-opened automatically.
342
343 The "Filter" condition may include IBX style parameters. In which case, their
344 value must be set by the dataset's "OnBeforeOpen" event handler.
345
346 This is a public property for TIBDataSet and TIBQuery query and intended for
347 use at run time.
348
349 Note: The property is a published property of TIBTable. The TIBTable functionality
350 is unaffected by this change.
351
352 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
353
354 1. Remove need to check for IsMultiThread by providing access to GUI timers via
355 IBGUIInterface. Note: master/detail delay timer does not apply to console
356 mode apps.
357
358 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
359 statement. This avoids problems if "Execute Block" is used as the Query.
360
361 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
362 internal SQL tokeniser routines.
363
364 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
365 as a select statement, with or without CTEs.
366
367 5. IBSQLParser: parser now recognises the "ROWS" clause.
368
369 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
370 internal SQL tokeniser routines.
371
372 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
373 being raised for valid set statements processed by a data formatter.
374
375 8. New published property for TIBDatabase and TIBXServicesConnection. This is
376 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
377 the path of the Firebird Library used by the database/services connection.
378
379 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
380 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
381 services connection.
382
383 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
384 or param name is not a valid SQL identifier.
385
386 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
387 view of whether the text box should be editable when no DataSource is specified.
388 TIBLookupComboEditBox has been updated to workaround this problem. As long as
389 ReadOnly is false, the text box is editable when no DataSource is specified.
390
391 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
392 the FBLIB environment variable. If you do not want to permit this then you
393 must modify the Register procedure in the design/IBDBReg.pas unit to remove
394 this setting.
395
396 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
397
398 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
399 Utf8EscapeControlChars
400
401 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
402
403 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
404 all previous copies of the IBX source code tree before installing this release.
405
406 The IBX packages used by most users have not changed, with one exception. The
407 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
408 to use the IBServices unit in your applications, please add the iblegacyServices
409 to the list of dependencies. To do this, open the Project Inspector and select
410 Add->New Requirement and select "ibLegacyServices" from the list of available
411 packages.
412
413 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
414 the IBServices unit providing what is intended to be a clearer and easier to
415 use set of IB Services components. See Chapter 10 of the IBX User Guide for
416 more information and the guide to "Firebird Service Management Using IBX".
417 As indicated above, the legacy services components are still available and
418 provided in a separate package. There is no need to update working applications
419 using the older versions except for an additional package dependency.
420
421 2. The IBX packages and source code tree have been re-organised in an attempt to
422 finally get rid of the "duplicate ppu" warnings. This re-organisation should
423 not affect existing users. Section 2.3 of the IBX User Guide describes the
424 new set of IBX packages.
425
426 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
427 updated to use the new Services API components.
428
429 4. The iblocal package has been updated to use the new Services API components.
430
431 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
432 TIBXSecurityService. It had been wrongly classified in the previous version
433 as a per database configuration item. It is global to a server and hence
434 correctly positioned as part of the Security Package. In the DBAdmin example,
435 the setting has moved to the mappings page.
436
437 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
438 are ignored.
439
440 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
441 closed before the database is dropped. Before and After Disconnect event handlers
442 are also fired.
443
444 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
445 is started and not just the first time.
446
447 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
448 depenendency with comp type.
449
450 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
451
452 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
453 then this is recognised and not ignored.
454
455 12. TIBDataSet, TIBQuery, TIBTable: additions:
456 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
457 function GetPerfStatistics(var stats: TPerfCounters): boolean;
458 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
459
460 GetRowsAffected returns the affected row counts from the last insert/update/delete
461 if EnableStatistics = true then GetPerfStatistics returns the current stats
462 counters for the select query. Note: stats accumulate after each fetch from
463 the database. To get total query cost after open, call the "Last" method
464 and then GetPerfStatistics.
465
466 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
467
468 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
469 in parenthesises.
470
471 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
472 SQL identifiers are always delimited by double quotes. If false, then they are
473 only delimited if the identifier is a reserved word, contains lower case or special
474 characters. Set this property to true to retain previous behaviour.
475
476 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
477 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
478
479 16. TIBDataSet, TIBQuery, TIBTable: addition:
480 property MasterDetailDelay: integer {defaults to zero}
481
482 When non-zero and the dataset is a detail table referencing a master table
483 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
484 then a synchronisation delay is added (in milliseconds) between the master
485 row changing and the detail dataset being re-opened. If the master dataset
486 is scrolled before the delay expires then the delay is reset. This can be used
487 to avoid performance overheads when scrolling through a large master dataset.
488
489 Note: uses fptimer and hence requires a thread manager. Under Linux the
490 chreads unit must be included in your project. TTimer is not used in order
491 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
492
493 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
494 with Extract Option eoDatabase.
495
496 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
497 When a deLayoutChanged event is reported on the ListSource dataset, the
498 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
499 relationship with the control's datasource (master).
500
501 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
502
503 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
504 stubs. Pedantic fix really, as procedures output in dependency order anyway.
505
506 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
507 DDL (Firebird 3 and later only).
508
509 22. TIBLookupComboBox Autocomplete Fixes:
510 i. Only appended text is now selected after autocomplete.
511 ii. Uppercase keys no longer ignored for autocomplete.
512 iii. Retain Prefix case is now honoured correctly.
513 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
514 before autocomplete performed. i.e. behaviour now the same as when
515 no DataSource assigned.
516
517 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
518 between SQL statements.
519
520 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
521 ObjectNames are converted to upper case before matching against metadata object
522 names, unless the objectname is delimited by double quotes, in which case, the
523 double quotes are removed and the remaining string is used (unmodified) to match
524 against the metadata object name.
525
526 If true then the ObjectName is used as is without modification and matched
527 against the metadata object name. No attempt is made to remove double quotes.
528
529 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
530 with eoTrigger, these extract types can be used to select only Database Triggers,
531 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
532
533 26. TIBXScript: If an exception occurs during the processing of a statement, the
534 statement separate character is now reset to the default (';').
535
536 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
537
538 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
539 a commit or reconnect statement and instead activated only when next SQL statement
540 is executed.
541
542 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
543
544 30. TIBXScript: case insensitive regex now used when matching statements instead of
545 converting statement to upper case.
546
547 31. TIBExtract: metadata comments now supported. New published property
548 IncludeMetaDataComments (default true). If true then metadata comments included
549 in extracted DDL. New Extract Object member eoComments. This may be used with
550 ExtractObject method to list all metadata comments.
551
552 32. TIBExtract: ListObjectNames method added.
553
554 33. Updated Database component editor to support additional connection string
555 types.
556
557 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
558
559 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
560 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
561 RELEASE.
562
563 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
564
565 1. IBExtract: Identity columns - add additional check for null column for generator name.
566
567 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
568 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
569 information). However, this is also a very useful mechanism for returning updated computed by
570 column values. Values returned as a result of executing an Insert or Update statement
571 replace existing values in the current row for each corresponding column.
572
573 Previously, if a dataset's select query included read only (computed by) fields then
574 an automatic row refresh was performed after an insert or update query had been processed,
575 irrespective of the setting of the "ForcedUpdates" property. This has changed such
576 that an automatic refresh is no longer performed if an insert or update query contains
577 a returning clause that updates one or more fields on the current row. A full row
578 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
579 field values and the select query contains read only fields. Use of Insert/update
580 returning should be significantly more efficient than executing a refresh query.
581
582 This behaviour change is intended to be backwards compatible and there should be no need to change
583 existing programs, other than to improve performance by using the new capability.
584
585 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
586 they are called when the dataset row is being deleted, there is no value in
587 updating the current record from the query result. Instead, a new event handler
588 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
589 an OnDeleteReturning event handler is provided then it is called with the IResults returned
590 by the query. The event handler can then interrogate the query results and
591 perform whatever action is necessary. For example to confirm, to the user,
592 the deletion of a row with the returned values.
593
594 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
595 any Computed By or Identity Columns. The IBTables example has been updated to
596 illustrate the computation of the employee Full Name on update.
597
598 5. TIBTable: The GeneratorField property is now published.
599
600 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
601 When InsertSQL is generated, the Identity columns are not included in the list of values to
602 be inserted. A RETURNING clause is added to the insert statement to return the value of
603 each Identity column after the insert is executed.
604
605 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
606 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
607 Insert..Returning clause.
608
609 8. TIBGenerator: small performance improvement by not preparing query each time
610 a new value is generated.
611
612 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
613
614 10. Property editors will now sync table name to a System Table when "Include System
615 Tables" is selected and the query is for a System Table.
616
617 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
618 values are no longer converted to milliseconds from TDateTime and then back again
619 to TDateTime (the conversion to milliseconds is the default TDataset approach).
620
621 12. Property Editors handling of Stored Procedures.
622 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
623 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
624 query).
625 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
626
627 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
628 can be used to select a package. If non-empty, the stored procedure name is
629 expected to be a stored procedure defined in the specified package and the
630 generated SQL will be as required for a stored procedure located in a package.
631
632 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
633 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
634 which a stored procedure can be selected. With no package name selected, non-package
635 stored procedures are listed.
636
637 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
638 for password on reconnect.
639
640 16. TIBDatabase: use IAttachment for connection default character set id, code page
641 and character set name.
642
643 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
644 DB info lookups"
645
646 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
647
648 19. Add a property Editor for TIBUpdate.RefreshSQL.
649
650 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
651 parameters. This stops an exception being raised when the field cannot be
652 located in the record buffer.
653
654 21. Property Editors now automatically include System Tables when opened and when the query table
655 is a System Table.
656
657 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
658 This avoids errors due to a stale SQRB or SRB being used for the next query.
659
660 23. IBServices: Service attach parameters now include "expected_db". This is used to
661 add the SPB item isc_spb_expected_db. This names a database using
662 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
663 database. examples/services re-written to illustrate use of "expected_db".
664
665 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
666 This avoids truncated backups when the server returns a timeout (busy) response.
667
668 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
669
670 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
671 databasenames. These are respectively expanded to the local system's temp directory
672 (including trailing delimiter) or to a prescribed data directory (including
673 trailing delimiter). Under Unix systems the data directory is a hidden directory
674 in the user's home directory. The hidden directory name is either the string returned
675 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
676 Under Windows, the directory is the same as the Data Directory as decribed
677 above but instead prefixed by the User's application data path. These may be
678 used to improve application portability for Personal Databases.
679
680 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
681 this has not worked for a long time and is not useful either. FieldDefs should be
682 managed using the Fields Editor as with any other dataset. To access the fields
683 editor for a TIBTable component, double click on the component. The fields editor
684 is then displayed.
685
686 28. TIBDatabaseInfo: new properties/function
687 * DateDBCreated (returns date/time database created)
688 * TransactionCount (returns no. of active transactions)
689 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
690 * PagesFree (Firebird 3 or later)
691 * PagesUsed (Firebird 3 or later)
692 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
693 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
694
695 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
696
697 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
698
699 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
700 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
701
702 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
703 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
704 firing during backup and restore.
705
706 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
707 for verbose output using the new property "StatisticsRequested".
708 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
709
710 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
711
712 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
713 palette. This uses the online validation feature added in Firebird 2.5. The
714 services's properties enable inclusion/exclusion of tables and indexes using
715 regular expressions. See.
716 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
717
718 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
719 option on a database.
720
721 37. TIBCustomService: Assign method implemented to allow copying of service login
722 context between service API components. "Detach" method now only detaches
723 service when last reference to the service interface detaches. Tidy up of
724 code for SetActive and Attach methods including password hiding.
725
726 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
727 and used to determine the auth method and protocol used for the connection.
728
729 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
730 a Create Database Statement generated by IBX.
731
732 40. All IBServices now have an additional published property "PortNo". This may
733 be set to a non-standard port number when necessary. If zero then the default
734 port number is used.
735
736 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
737 and not just the mouse.
738
739 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
740
741 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
742 image index and selected image index for each node to be set from a database field.
743
744 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
745 then database schema includes grants to all users. If not present then the
746 only user grants included are those to User PUBLIC.
747
748 45. TIBTreeView: performance improvement. When expanding include both expanded node
749 and child nodes in dataset.
750
751
752 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
753
754 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
755 changes.
756
757 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
758 Bug could result in truncated multi-byte character set values.
759
760 3. Changes consequential on moving fbintf character set utility functions from
761 IFirebirdAPI to IAttachment.
762
763 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
764
765 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
766 results in autocomplete ignoring prefix text.
767
768 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
769 entering a new name into the text box.
770
771 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
772 Firebird rather than recomputing it.
773
774 8. Property Editor positioning tidy up: All IBX Property editors should now be
775 screen centre. Previously some were "poDesigned" which may be inappropriate
776 for multi monitor desktops.
777
778 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
779
780 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
781 a transaction and always reset the object.
782
783 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
784
785 13. TIBXScript: Allow for override of database filename in Create Database statements.
786
787 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
788 to a gbak format archive.
789
790 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
791
792 16. IBLocaldb: Drop database if error creating an empty database.
793
794 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
795 unless selected node not in current dataset.
796
797 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
798 to TIBCustomService, and IBlocalDB code tidy up.
799
800 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
801 behaviour due to uninitialised variable.
802
803 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
804 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
805
806 21. IBSQL: When Database changed ensure that all resources are freed.
807
808 22. IBCustomDataset: When database changed ensure that queries an unprepared.
809
810 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
811 * Line Wrap on SQL Token boundaries (on user command)
812 * auto-complete table names in drop down list of table names
813 * Double click on tablename or field name adds to SQL text
814
815 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
816
817 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
818 TVariantArray. Seems to avoid memory corruption in Windows (probably a
819 workaround for a problem in fpc 3.0.4 win64).
820
821 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
822
823 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
824
825 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
826
827 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
828 include remote system name.
829
830 2. TIBExtract: No longer include comment header and COMMIT statement for empty
831 tables when data included in output.
832
833 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
834 and timing information to be written to stdout. This may be used to locate
835 performance bottlenecks.
836
837 4. SQLParser: only call "OnChanging" event handler when value is different.
838
839 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
840
841 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
842 that BindFields is called when the query is next activated. Avoids FieldName
843 not found error.
844
845 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
846 purpose and allows the programmer to define any action they want for Update, Insert
847 or Delete. This may be complex SQL (similar to a Trigger), application specific
848 filtering of updates, or use of statements such as Grant or Revoke instead of
849 normal DML. See User Manual for more information.
850
851 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
852
853 1. TIBEvents: Fix uninitialised variable that could result in lost events.
854
855 2. TIBExtract: Added support for FB3 "USAGE" privilege.
856
857 3. TIBExtract: data formatted as Charset set "octets" is now output using
858 hexadecimal notation.
859
860 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
861 using a simple XML format.
862
863 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
864 grants to these objects.
865
866 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
867 dependency problems restoring complex databases.
868
869 7. TIBXScript: This component has been restructured to allow for the processing of
870 embedded XML in INSERT statements and to support interactive sources in addition
871 to non-interactive data sources such as files.
872
873 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
874
875 9. TIBXScript: ISQL compatiable Set statements are now supported:
876 SET SQL DIALECT
877 SET TERM
878 SET AUTODDL
879 SET BAIL
880 SET ECHO
881 SET COUNT
882 SET STATS
883 SET NAMES <character set>
884
885 10. IBVersion unit added to hold current IBX Version Number information.
886
887 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
888 and domain definitions.
889
890 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
891 fully supported.
892
893 13. TIBExtract: when a database dump includes data, the generator values are now also set.
894
895 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
896
897 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
898
899 See also doc/IBX4LazarusGuide.pdf for important information on
900 upgrading to IBX2.
901
902 1. Size property of TIBStringField is now the width in characters of the field
903 and not the byte length. This applies only to multi-byte character sets such
904 as UTF8. The original approach aligned with TStringField. However, the TStringField
905 code is not recognised as a bug and hence this change to align the behaviour.
906 The TStringField change is expected in fpc 3.2.0.
907
908 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
909 true (default) then Size property value saved in the lfm is ignored. Size is
910 always set from the dynamic information read from the database. It is unclear
911 why anyone would want to override this and set Size to false.
912
913 3. ibxscript: should now handle correctly a Case..End statement within a procedure
914 block.
915
916 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
917 exist when an attempt is made to connect to it (run time only) then an attempt
918 is made to create the database.
919
920 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
921 has been successfully created as a result of a call to CreateDatabase or when
922 creating a database after it was found not to exist.
923
924 6. DBControlGrid: a race condition could result in the wrong row image being
925 written to the cache. This has been avoided by a trip round the message
926 loop before rendering the row image.
927
928 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
929 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
930 known to risk corrupt rendering of row images when the control is first
931 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
932 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
933
934 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
935 a TDateEdit control located on an editor panel.
936
937 9. TIBExtract: brought up-to-date plus many bug fixes.
938
939 10. DBControlGrid: Removed memory leak when updating rows.
940
941 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
942
943 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
944
945 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
946 when target codepage is CP_NONE. This is a workaround for
947 http://bugs.freepascal.org/view.php?id=30622.
948
949 2. DBLog option removed from TIBStatisticalService - not supported by server
950 since Firebird 1.5.
951
952 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
953 similar.
954
955 4. IBCodePage: updated mapping between codepages and character id.
956
957 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
958 Firebird. Character sets with a char width of two are not UTF16.
959
960 6. Strings received from the database are now always transliterated into UTF8
961 regardless of the database character set or connection character set. This
962 is for compatibility with the LCL.
963
964 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
965
966 1. IBBlob: Defer reading of blob until read method called. This avoids having to
967 read in an entire blob just to get the size of the blob. General performance
968 improvement when opening datasets containing blobs.
969
970 2. Clearing a Blob now sets the corresponding field's modified flag.
971
972 3. IBLookupCombo: When not performing auto-complete, original query sort order
973 is now used.
974
975 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
976 determined.
977
978 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
979
980 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
981 lazarus 1.6.0
982
983 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
984 compilation error.
985
986 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
987
988 1. No character set specified for connection: when a text blob is retrieved, the
989 character set is determined by looking up the native character set using then
990 Firebird API. Otherwise a text mode blob is assumed to have the same character
991 set as the connection.
992
993 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
994 for Login Dialog returing a change to the database path.
995
996 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
997 to be changed from that given in the TIBDatabase/TIBServer component and for the
998 entered value to be saved on a project specific basis (design time only).
999
1000 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1001 column fieldname. If they are the same then it is acts as a look up for the KeyValue
1002 Otherwise, it sets the column text to the selected ListField Value.
1003
1004 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1005 column width.
1006
1007 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1008 and a case insensitive search is requested.
1009
1010 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1011 or column ListSource.
1012
1013 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1014 unprepare) when closing and the text has not changed.
1015
1016 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1017 Less likely to cause a cursor re-use error on Windows.
1018
1019 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1020 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1021
1022 11. TIBTreeView: Guard against nil destination on record changed
1023
1024 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1025 string type with the code page set to reflect the returned field encoding after
1026 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
1027 earlier versions.
1028
1029 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1030 will now result in transliteration to the code page specified for the Firebird driver
1031 if the assigned string has a different code page. FPC 3.0.0 onwards only.
1032
1033 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1034 is ignored and the lc_ctype value, when the database is opened, is set to align with
1035 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1036 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1037 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1038 the GETACP is used to determine the Windows code page.
1039
1040 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1041 name used as the lc_ctype when the database was opened. Only valid while the
1042 Database is connected.
1043
1044 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1045 id that corresponds to the DefaultCharSetName.
1046
1047 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1048
1049 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1050 path is given and database attach fails due to access permission issues on the
1051 temp directory or security database, then the attach is retried with "localhost:"
1052 prefixing the databasename. This should avoid problems when the database has to
1053 be accessed by a local (e.g. classic) server and libfbembed is used.
1054
1055 2. Windows: revised search order for Firebird DLL:
1056 i. The Firebird Embedded Server in the application Directory.
1057 ii. If the FIREBIRD environment variable is set then the directory this
1058 points to is searched for the FB Client DLL and then then underlying
1059 "bin" directory.
1060 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1061 is used to locate the Firebird installation directory and the underlying
1062 "bin" directory is searched for the FB Client DLL.
1063 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1064 are searched for the FB Client DLL.
1065 v. The PATH Environment variable is used to search for the FB Client DLL.
1066 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1067
1068 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1069 See doc/readme.scriptengine and example applications.
1070
1071 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1072 simplify the use of the embedded firebird server on both Linux and Windows platforms.
1073 See dpc/readme.localdatabase and example applications.
1074
1075 5. IBDynamicGrid: Reordering on column header click should now also work for
1076 dynamic columns.
1077
1078 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1079 between incrementing/decrementing the lock count and signalling the event.
1080
1081 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1082
1083 1.3.2 was never formally released and only made available as beta copies.
1084
1085 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1086
1087 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1088
1089 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1090
1091 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1092 i.e. when it is a calculated field
1093
1094 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1095 This problem was due to a race condition between recalculating row heights and
1096 determining which row was selected by the mouse click. The row height calculation
1097 is now deferred by an extra trip round the message loop allowing the row to
1098 be always calculated on the current grid layout rather than risking it being
1099 calculated on the grid layout after the expanded row has been shrunk.
1100
1101 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1102 Windows.
1103
1104 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1105 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1106 to be determined at runtime. See doc/readme.charactersets.html.
1107
1108 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1109 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1110
1111 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1112 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1113 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1114
1115 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1116 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1117 implies no truncation.
1118
1119 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1120
1121 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1122 (avoids "Not in Edit Mode" error).
1123
1124 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1125
1126 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1127 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1128
1129 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1130
1131 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1132
1133 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1134
1135 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1136
1137 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1138
1139 1. OnCloseUp Event Handler added to TDBLookupProperties
1140
1141 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1142 problem with row size when exception is called.
1143
1144 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1145
1146 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1147 in a TCustomComboBox and ignores return key if in a TCustomMemo
1148
1149 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1150 keyed in i.e. when autocomplete not performed
1151
1152 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1153 console mode applications with all LCL required functions (builtin dialogs and
1154 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1155 not included in your project, IBX should compile and link with a console mode program.
1156 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1157 console mode application or the IDE will automatically assume that your
1158 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1159
1160 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1161 to use the built in dialogs and cursor management. IBDialogs is
1162 included by default if "ibexpress" is in your project source's "uses" clause.
1163 This should be the case for all projects created through the IDE. This is why
1164 you do not want to add the ibexpress package to console mode applications. The
1165 ibexpressconsolemode package has been created to allow console mode programs
1166 to avoid adding LCL dependencies when using IBX, while still having the
1167 unit search paths set up correctly.
1168
1169 Existing users should check to ensure that the "ibexpress" unit is included in
1170 each project's source file (*.lpr).
1171
1172 You may find that in order for the IDE to recognise that ibexpressconsolemode
1173 exists, you have to first open the package in the IDE and then close it. This
1174 adds it to the most recently accessed packages list. To make it permanently
1175 available, add the package name to lazarus' staticpackages.inc file.
1176
1177 Thanks to Julio Jiménez for suggesting support of console mode.
1178
1179 7. SQL Parser can now accept quoted strings that include new lines
1180
1181 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1182 of text on start of edit. This is particularly useful when tabbing to a
1183 column and then inserting text.
1184
1185 9. New Examples provided for IB Services and ISQLMonitor.
1186
1187 10. Fix error when writing to blob streams that recorded only the last buffer
1188 write in the blob stream. In most cases, this did not cause a problem as the
1189 IB Blob Stream is written in a single write. However, with the TDBImage, write
1190 of a graphic type prefix was lost which caused a problem when the image could
1191 not be automatically recognised.
1192
1193 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1194 already open" errors due to random numbers used for the cursor name being identical.
1195
1196 12. IBTable: corrected error that could result in an "Index out of bounds" error
1197 when opening the table and the Primary Key is the last or only column in the
1198 table. Thanks to Rick Hoover for the fix.
1199
1200 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1201 of "UTF-8", and update list of available database character sets. Existing
1202 users should check the current lc_ctype setting in their applications.
1203
1204 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1205
1206 1. Firebird Services: avoid List Index error when opening a service with an
1207 empty Params property.
1208
1209 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1210 Link now set up in Loaded method - avoids occasional failure to apply
1211 SQL markup on initial open.
1212
1213 3. "Employees" example performance improvements when scrolling.
1214
1215 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1216 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1217 random image cached).
1218
1219 5. DBControlGrid: Should now react to changes in panel height at run time.
1220
1221 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1222 even when further rows exist.
1223
1224 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1225 always be derived from panel height and setting this property can cause confusion.
1226 Note for existing projects: to avoid a missing property error at run time,
1227 each form using the DBControlGrid must be opened, updated and saved in the IDE
1228 in order to remove the property value from the lfm.
1229
1230
1231 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1232
1233 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1234 call Prepare before setting parameter values.
1235
1236 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1237
1238 3. Code tidyup and more robust handling of dsql information result vector.
1239
1240 4. Support for centralised handling of transaction status changes. TIBTransaction
1241 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1242 and "AfterExecQuery". The first three are called after the same event is called
1243 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1244 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1245 enable monitoring of transaction status changes for a given transaction to be
1246 handled in a single place. For example, when a change to the dataset occurs
1247 an indicator can be set that shows the user that in order to save changes,
1248 the transaction should be committed. Rather than doing this per dataset, this
1249 can now be done per transaction.
1250
1251 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1252 the dataset is scrolled. However, any changes to the current row are, by default,
1253 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1254 have a new property "DataSetCloseAction" that adds automatic posting of changes
1255 on dataset close. If this property is set to dcDiscardChanges (default) then the
1256 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1257 then IBX will attempt to post any unsaved changes before the dataset is closed
1258 (and after the BeforeClose event handler is called). The exception is when the
1259 dataset is being closed as a result of a transaction rollback. In this case,
1260 no action is taken and any unsaved changes are discarded. This avoids both
1261 unnecessary overhead and the risk that a validation error may occur in the Post
1262 raising an exception and thereby preventing a rollback.
1263
1264 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1265 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1266 width. Display Widths are now corrected by dividing by the max byte width per character.
1267 For UTF8 character sets, the byte width is four and hence the Display Width will be
1268 the byte width divided by 4. The byte width of each character set is determined
1269 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1270 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1271
1272 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1273
1274 8. IBLookupComboEditBox: List should now always be restored to full list when the
1275 control loses focus. Default Key press default interval reduced to 200ms.
1276
1277 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1278 when dataset rows are less than visible rows.
1279
1280 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1281 does not exist or DataSet is empty. More responsive on dataset open. New event
1282 OnRestorePosition. Column sort disabled if no header row.
1283
1284 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1285 while dataset state is dsInsert. Avoids posting errors.
1286
1287 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1288 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1289
1290 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1291
1292 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1293 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1294 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1295 always "posts" the current record regardless or whether or not it may be more appropriate
1296 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1297 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1298 as the first action of the "Post" method and allows the handler to convert the Post
1299 into a Cancel if that is the appropriate action on moving to a different row. This is
1300 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1301 raised here, but it may still be more appropriate to validate a post and signal
1302 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1303
1304 15. On Unix derived systems, the Firebird library name can now be given as a colon
1305 separated list. Each library name on the list is tried in turn, in left to right
1306 order with the first found being used as the firebird library. By default, on Linux,
1307 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1308 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1309
1310 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1311 then it will still attempt to access the database via the Firebird Server and will
1312 require a username and password. If only the pathname is given, then the username
1313 and password should be omitted and the unix file permissions are used to grant
1314 access.
1315
1316 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1317
1318 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1319 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1320 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1321 corresponds to a row of the linked DataSource. Any data aware control on the
1322 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1323
1324 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1325 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1326 takes place during database access. This may be useful when there are performance issues with
1327 the change of cursor. Setting the property to false suppresses the change of cursor.
1328
1329 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1330 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1331 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1332 making all changes permanent immediately rather than when the transaction is explicitly
1333 committed.
1334
1335 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1336 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1337
1338 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1339
1340 Development version only.
1341
1342 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1343
1344 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1345 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1346 "Where" and "Having" clauses to implement user specified filters of arbitrary
1347 complexity.
1348
1349 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1350 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1351 These are:
1352
1353 - TIBLookupComboEditBox
1354 - TIBDynamicGrid
1355 - TIBTreeview
1356
1357 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1358 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1359 to revise the available list and restrict it to items that are prefixed by the
1360 typed text (either case sensitive or case insensitive). Autoinsert allows a
1361 newly typed entry to be added to the list dataset and included in the available
1362 list items.
1363
1364 TIBDynamicGrid is a TDBGrid descendent that provides for:
1365 - automatic resizing of selected columns to fill the available row length
1366 - automatic positioning and sizing of a "totals" control, typically at the
1367 column footer, on a per column basis.
1368 - DataSet resorting on header row click, sorting the dataset by the selected column.
1369 A second click on the same header cell reversed the sort order.
1370 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1371 is automatically expanded and a panel superimposed on it. The panel can have any
1372 number of child controls, typically data aware controls with the same datasource
1373 as the grid allowing for editing of additional fields and more complex editors.
1374 - Reselection of the same row following resorting.
1375 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1376 Its properties are specified on a per column basis and allows for one or more
1377 columns to have their values selected from a list provided by a dataset.
1378 Autocomplete and autoinsert are also available. The existing picklist editor
1379 is unaffected by the extension.
1380
1381 TIBTreeView is a data aware TCustomTreeView.
1382
1383 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1384 zero scale will no longer return an error. An Int64 will be returned instead.
1385
1386 4. TIBTransaction now has events for Before and After Transaction End and a new function
1387 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1388
1389 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1390 repeated multiple times.
1391
1392 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1393 check used to get in the way of using Stored Procedures, and "Update or Insert"
1394 statements.
1395
1396 7. Insert, Modify and Delete property Editors now support Query Generation from
1397 Stored Procedures.
1398
1399 8. Three new examples illustrate the use of the new IB Controls

1402 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1403
1404 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1405 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1406 Gabor Boros for reporting this problem and for testing the improvements).
1407
1408 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1409 See readme.field+param.names in the doc folder.
1410
1411 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1412 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1413
1414 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1415
1416 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1417 actions.
1418
1419 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1420 thanks to Yuriy Kopnin for pointing this out).
1421
1422 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1423
1424 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1425 for both fields and parameter setting.
1426
1427 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1428 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1429
1430 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1431 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1432
1433 11. TIBTable now has a property editor for "MasterFields"
1434
1435 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1436 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1437
1438 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1439 of settings is unrecognised. Selecting this radio button has no effect on the settings.

1442 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1443
1444 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1445
1446 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1447
1448 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1449 it is null. This allows for alternative user defined setting of the generator
1450
1451 Many thanks to Julio Jiménez for this fix
1452
1453 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1454 and suggests that the user may have forgotten to install it.
1455
1456 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1457
1458 1. Conditional compilation used to limit registration of TIntegerField to
1459 Lazarus versions less than 1.1
1460
1461 2. When a database connection is created, character set is now by default set
1462 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1463 1250 to 1254.
1464
1465
1466 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1467
1468 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1469
1470
1471 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1472
1473 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1474 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1475
1476 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1477 package is changed to do this (which it should do).
1478
1479 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1480
1481 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1482
1483 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1484
1485 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1486
1487 4. Property editors should now correctly resize.
1488
1489 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1490 (restored original functionality)
1491
1492 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1493 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
