1 > IBX Change Log  version (2.5-1 Build nnn) Tue, 6 Dec 2022 23:13:00 +0000
2 >
3 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
4 >
5 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
6 >
7 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
8 >
9 > 1. TIBTransaction: new properties
10 >    property TransactionID: integer read GetTransactionID;
11 >    property IsReadOnly: boolean read GetIsReadOnly;
12 >    {published}
13 >    property TransactionName: string read FTransactionName write SetTransactionName;
14 >
15 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
16 >   Insert or Update...Returning. This allows blobs and arrays to be returned
17 >   by the statement.
18 >
19 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
20 >
21 > 4. TransactionName initialised to a newly generated GUID if empty.
22 >
23 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
24 >   for the fbintf package's journaling capability. TIBJournal is used to set the
25 >   file path and filename for the journal file and to Enabled (start journaling) and
26 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
27 >   more information, and comments in IBJournal.pas.
28 >
29 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
30 >
31 > 7. Bug fix: blob id no longer set to null on update when blob has not been
32 >   retrieved.
33 >
34 > 8. Row auto refreshed on update/insert if blob or array field updated and field
35 >   not in a returning clause.
36 >
37 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
38 >   buffer overhead and avoids problem when refresh query has a different column
39 >   count to select query i.e. incorrectly changing number of columns.
40 >
41 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
42 >
43 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
44 >    string. Note that the Version property returns an InterBase compatible version string.
45 >
46 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
47 >
48 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
49 >
50 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
51 >   This is for compatibility with Firebird 5 where Update...Returning can return
52 >   a cursor.
53 >
54 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
55 >
56 > 1. Add try-..except check when initially loading library in IDE. This should
57 > ensure that IDE continues to load even when a failure occurs in IBX load
58 > library.
59 >
60 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
61 >   hence will correctly detect end of the outer containing block when the block
62 >   contains a SELECT ... CASE ... END construct.
63 >
64 > 3. IBExtract: some further tidying up to remove extraneous white space.
65 >
66 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
67 >   errors when extra elements are added to DB.TFieldType.
68 >
69 > 5. IBUpdate: updated to reflect changes to ISQLParam.
70 >
71 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
72 >
73 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
74 >
75 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
76 >
77 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
78 >
79 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
80 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
81 >
82 > 2. TIBSQL: Batch Update/Insert support added.
83 >
84 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
85 >   is no longer automatically converted to upper case when it is syntactically a
86 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
87 >   as CREATE PROCEDURE "iCASE".
88 >
89 >   There could be a backwards compatibility issue when the StoredProcName was entered
90 >   manually at design time. That is not selected from the drop down list. If the
91 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
92 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
93 >   ensure that the value of the StoredProcName is all upper case, unless it was
94 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
95 >   quotes).
96 >
97 >   Note that when a stored procedure name was declared delimited in double quotes,
98 >   as in the first example above, the value of the StoredProcName property must not
99 >   include the delimiters (double quotes).
100 >
101 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
102 >   upgrade.conf was not found. This replaces silently ignoring the problem.
103 >
104 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
105 >   'Version.%.3d' and is used to generate the section header names (for a given
106 >   version no.) in the upgrade.conf file.
107 >
108 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
109 >
110 > 1. -c command line option added to fbsql example program. Used to set connection
111 >   character set.
112 >
113 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
114 >
115 > 1. Firebird 4 support added.
116 >
117 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
118 >   extended precision NUMERIC fields are supported.
119 >
120 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
121 >
122 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
123 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
124 >
125 > 5. IBExtract now supports FB4 enhancements:
126 >   - new data types as above
127 >   - Identity column extensions
128 >   - Default user role
129 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
130 >   - Internal Functions
131 >
132 > 6. IBExtract: new event: OnExtractLines.
133 >
134 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
135 >
136 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
137 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
138 >
139 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
140 >   format for rendering a time zone.
141 >
142 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
143 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
144 >
145 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
146 >    IIBGUIInterface and IIBTimerInf respectively.
147 >
148 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
149 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
150 >
151 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
152 >    truncated to its fixed character width rather than being right padded with
153 >    white space to the maximum data size.
154 >
155 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
156 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
157 >    also empty.
158 >
159 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
160 >
161 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
162 >    connect string. The database name is extracted from the connect string.
163 >
164 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
165 >
166 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
167 >
168 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
169 >    not being present as required.
170 >
171 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
172 >    version that can be customised to work with other database drivers.
173 >
174 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
175 >    unnecessary CR at end of line on Unix platforms.
176 >
177 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
178 >    seconds in order to reduce risk of message loss.
179 >
180 > 23. ISQLMonitor: read and write count statistics now available via:
181 >      property TIBSQLMonitor.ReadCount;
182 >      IIBSQLMonitorHook.GetWriteCount: integer;
183 >
184 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
185 >
186 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
187 >
188 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
189 >    number of UTF8 characters exceeds the string size then string is truncated
190 >    to the maximum string size. This is  usually a problem with fixed width columns
191 >    right padded with white space.
192 >
193 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
194 >    If SQLFiltered is set then when a dataset is opened, each line in the
195 >    SQLFilterParams property is assumed to be a SQL condition clause and
196 >    ANDed into the Where clause of the SQL Select statement provided as a
197 >    dataset property. Each such SQL condition thus acts as an additional filter
198 >    on the dataset.
199 >
200 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
201 >    side filters).
202 >
203 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
204 >   text matches complete entry.
205 >
206 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
207 >   dataset are active (avoids risk of access violation if master is inactive)
208 >
209 > 6. TIBEvents: Registered property can now be set at design time even if database not open
210 >
211 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
212 >   This should prevent "spillover" of events between sessions.
213 >
214 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
215 >   This should ensure that the internal buffer is set up correctly and avoids
216 >   a duplicate initial row.
217 >
218 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
219 >   That is, the DataSize should be the field size * character set width. The
220 >   value returned by DataSize is now the same as the Dataset buffer size reserved
221 >   for the field.
222 >
223 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
224 >
225 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
226 >    and vice-versa. This may result in an exception being raised (correctly) for
227 >    older programs when using dataset fields added to a form and the database has been
228 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
229 >    In such cases, the field needs to be deleted in the IDE fields editor and then
230 >    added back in.
231 >
232 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
233 >    false if query contains only white space and not just empty.
234 >
235 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
236 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
237 >    is cancelled.
238 >
239 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
240 >    called on a null field.
241 >
242 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
243 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
244 > set.
245 >
246 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
247 >    a cached update is applied and an exception is raised.
248 >
249 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
250 >
251 > 17. Console Mode Local Database support: backup/restore should now work correctly.
252 >
253 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
254 >    possible and an exception raised.
255 >
256 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
257 >    below this version no. and upgrade not possible.
258 >
259 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
260 >
261 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
262 >    not SQL Identifiers are now supported.
263 >
264 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
265 >    passed to the Firebird engine for execution.
266 >
267 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
268 >    is made to scroll back.
269 >
270 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
271 >
272 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
273 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
274 >
275 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
276 >   validated. If no match is found in the list of field names and the database has
277 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
278 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
279 >
280 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
281 >   with fpc 3.2.
282 >
283 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
284 >
285 >
286 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
287 >   and is used to override the default settings in the client side "firebird.conf" This
288 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
289 >   Each line of the string list should be a setting in the same format as "firebird.conf".
290 >   For example "WireCompression = true" in order to request wire compression on the client side.
291 >
292 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
293 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
294 >   also require a compatible setting in the server side "firebird.conf". For example
295 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
296 >   compression to be used.
297 >
298 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
299 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
300 >   ibx/examples/dbinfo for examples of how to display this information.
301 >
302 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
303 >   is a "convenience" property. If set the "WireCompression=true" is added to the
304 >   ConfigOverrides. If unchecked then this setting is removed.
305 >
306 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
307 >   not "INT64".
308 >
309 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
310 >   These are:
311 >    property TimestampFormat: string;
312 >    property DateFormat: string;
313 >    property TimeFormat: string;
314 >
315 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
316 >   DATETIME and TIME. The format strings use the standard FPC date/time format
317 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
318 >
319 >   If any of the above properties are set to an empty string, then the locale default
320 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
321 >   locale default is extended by appending '.zzz' to include milliseconds.
322 >
323 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
324 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
325 >
326 > 5. New published property for TIBCSVDataOut:
327 >     property QuoteStrings: boolean (default true)
328 >
329 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
330 >   used to delimit each and every string in the output.
331 >
332 > 6. New published properties for TIBCSVDataOut:
333 >    property FieldSeparator: string;
334 >    property HeaderSeparator: string;
335 >
336 >   Respectively, these provide the separator character(s) used to separate fields
337 >   in data and header rows. Both default to ','.
338 >
339 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
340 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
341 >    property OnFormatTextString;
342 >
343 >   This event handler can be used to process text strings before they are included
344 >   in the output e.g. to replace unprintable characters with alternative strings.
345 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
346 >
347 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
348 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
349 >   and without raising and exception if it does not.
350 >
351 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
352 >   consistency with SQL queries.
353 >
354 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
355 >    When true, SQL statement parameter names are parsed case sensitive. Note for
356 >    TIBDataSet only applies to Select query.
357 >
358 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
359 >    an IDE exception.
360 >
361 > 12. LocalDBSupport: initial database creation should now work correctly
362 >    when the schema source is an sql file.
363 >
364 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
365 >    when defined, this handler will be called by the internal TIBXScript during
366 >    initial database creation when the schema source is an sql file and may be used
367 >    to provide a visual indication of progress in console mode.
368 >
369 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
370 >    to true while a new local database is being created and its schema populated.
371 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
372 >    when the database is disconnected/connected during the create DB procedure.
373 >
374 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
375 >    are now always ignored and replaced by the user name and password provided as
376 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
377 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
378 >    completely ignored if this property is true.
379 >
380 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
381 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
382 >    ImageIndex and SelectImageIndex values on AddNode.
383 >
384 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
385 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
386 >    the same database connection.
387 >
388 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
389 >    if provided, this should be an conditional SQL expression suitable for
390 >    including in an SQL Select statement "where" clause. If non-empty and the
391 >    "Filtered" property is true then the SQL expression provided as the value of
392 >    the "Filter" property is "ANDed" with any existing condition statement
393 >    in the SQL statement's "Where" clause.
394 >
395 >    If the "Filter" property is set at run time, the "Filtered" property is true
396 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
397 >
398 >    The "Filter" condition may include IBX style parameters. In which case, their
399 >    value must be set by the dataset's "OnBeforeOpen" event handler.
400 >
401 >    This is a public property for TIBDataSet and TIBQuery query and intended for
402 >    use at run time.
403 >
404 >    Note: The property is a published property of TIBTable. The TIBTable functionality
405 >    is unaffected by this change.
406 >
407 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
408 >
409 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
410 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
411 >   mode apps.
412 >
413 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
414 >   statement. This avoids problems if "Execute Block" is used as the Query.
415 >
416 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
417 >   internal SQL tokeniser routines.
418 >
419 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
420 >   as a select statement, with or without CTEs.
421 >
422 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
423 >
424 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
425 >   internal SQL tokeniser routines.
426 >
427 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions

458 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
459 > all previous copies of the IBX source code tree before installing this release.
460 >
461 > The IBX packages used by most users have not changed, with one exception. The
462 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
463 > to use the IBServices unit in your applications, please add the iblegacyServices
464 > to the list of dependencies. To do this, open the Project Inspector and select
465 > Add->New Requirement and select "ibLegacyServices" from the list of available
466 > packages.
467 >
468 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
469 >   the IBServices unit providing what is intended to be a clearer and easier to
470 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
471 >   more information and the guide to "Firebird Service Management Using IBX".
472 >   As indicated above, the legacy services components are still available and
473 >   provided in a separate package. There is no need to update working applications
474 >   using the older versions except for an additional package dependency.
475 >
476 > 2. The IBX packages and source code tree have been re-organised in an attempt to
477 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
478 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
479 >   new set of IBX packages.
480 >
481 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
482 >   updated to use the new Services API components.
483 >
484 > 4. The iblocal package has been updated to use the new Services API components.
485 >
486 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
487 >   TIBXSecurityService. It had been wrongly classified in the previous version
488 >   as a per database configuration item. It is global to a server and hence
489 >   correctly positioned as part of the Security Package. In the DBAdmin example,
490 >   the setting has moved to the mappings page.
491 >
492 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
493 >   are ignored.
494 >
495 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
496 >   closed before the database is dropped. Before and After Disconnect event handlers
497 >   are also fired.
498 >
499 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
500 >   is started and not just the first time.
501 >
502 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
503 >   depenendency with comp type.
504 >
505 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
506 >
507 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
508 >    then this is recognised and not ignored.
509 >
510 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
511 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
512 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
513 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
514 >
515 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
516 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
517 >    counters for the select query. Note: stats accumulate after each fetch from
518 >    the database. To get total query cost after open, call the "Last" method
519 >    and then GetPerfStatistics.
520 >
521 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
522 >
523 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
524 >    in parenthesises.
525 >
526 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
527 >    SQL identifiers are always delimited by double quotes. If false, then they are
528 >    only delimited if the identifier is a reserved word, contains lower case or special
529 >    characters. Set this property to true to retain previous behaviour.
530 >
531 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
532 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
533 >
534 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
535 >       property MasterDetailDelay: integer {defaults to zero}
536 >
537 >    When non-zero and the dataset is a detail table referencing a master table
538 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
539 >    then a synchronisation delay is added (in milliseconds) between the master
540 >    row changing and the detail dataset being re-opened. If the master dataset
541 >    is scrolled before the delay expires then the delay is reset. This can be used
542 >    to avoid performance overheads when scrolling through a large master dataset.
543 >
544 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
545 >    chreads unit must be included in your project. TTimer is not used in order
546 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
547 >
548 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
549 >    with Extract Option eoDatabase.
550 >
551 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
552 >    When a deLayoutChanged event is reported on the ListSource dataset, the
553 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
554 >    relationship with the control's datasource (master).
555 >
556 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
557 >
558 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
559 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
560 >
561 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
562 >    DDL (Firebird 3 and later only).
563 >
564 > 22. TIBLookupComboBox Autocomplete Fixes:
565 >    i. Only appended text is now selected after autocomplete.
566 >    ii. Uppercase keys no longer ignored for autocomplete.
567 >    iii. Retain Prefix case is now honoured correctly.
568 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
569 >        before autocomplete performed. i.e. behaviour now the same as when
570 >        no DataSource assigned.
571 >
572 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
573 >    between SQL statements.
574 >
575 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
576 >    ObjectNames are converted to upper case before matching against metadata object
577 >    names, unless the objectname is delimited by double quotes, in which case, the
578 >    double quotes are removed and the remaining string is used (unmodified) to match
579 >    against the metadata object name.
580 >
581 >    If true then the ObjectName is used as is without modification and matched
582 >    against the metadata object name. No attempt is made to remove double quotes.
583 >
584 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
585 >    with eoTrigger, these extract types can be used to select only Database Triggers,
586 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
587 >
588 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
589 >    statement separate character is now reset to the default (';').
590 >
591 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
592 >
593 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
594 >    a commit or reconnect statement and instead activated only when next SQL statement
595 >    is executed.
596 >
597 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
598 >
599 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
600 >    converting statement to upper case.
601 >
602 > 31. TIBExtract: metadata comments now supported. New published property
603 >    IncludeMetaDataComments (default true). If true then metadata comments included
604 >    in extracted DDL. New Extract Object member eoComments. This may be used with
605 >    ExtractObject method to list all metadata comments.
606 >
607 > 32. TIBExtract: ListObjectNames method added.
608 >
609 > 33. Updated Database component editor to support additional connection string
610 >    types.
