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

440 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
441 >   or param name is not a valid SQL identifier.
442 >
443 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive

459 >
460 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
461 > all previous copies of the IBX source code tree before installing this release.
462 >
463 > The IBX packages used by most users have not changed, with one exception. The
464 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
465 > to use the IBServices unit in your applications, please add the iblegacyServices
466 > to the list of dependencies. To do this, open the Project Inspector and select
467 > Add->New Requirement and select "ibLegacyServices" from the list of available
468 > packages.
469 >
470 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
471 >   the IBServices unit providing what is intended to be a clearer and easier to
472 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
473 >   more information and the guide to "Firebird Service Management Using IBX".
474 >   As indicated above, the legacy services components are still available and
475 >   provided in a separate package. There is no need to update working applications
476 >   using the older versions except for an additional package dependency.
477 >
478 > 2. The IBX packages and source code tree have been re-organised in an attempt to
479 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
480 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
481 >   new set of IBX packages.
482 >
483 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
484 >   updated to use the new Services API components.
485 >
486 > 4. The iblocal package has been updated to use the new Services API components.
487 >
488 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
489 >   TIBXSecurityService. It had been wrongly classified in the previous version
490 >   as a per database configuration item. It is global to a server and hence
491 >   correctly positioned as part of the Security Package. In the DBAdmin example,
492 >   the setting has moved to the mappings page.
493 >
494 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
495 >   are ignored.
496 >
497 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
498 >   closed before the database is dropped. Before and After Disconnect event handlers
499 >   are also fired.
500 >
501 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
502 >   is started and not just the first time.
503 >
504 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
505 >   depenendency with comp type.
506 >
507 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
508 >
509 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
510 >    then this is recognised and not ignored.
511 >
512 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
513 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
514 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
515 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
516 >
517 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
518 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
519 >    counters for the select query. Note: stats accumulate after each fetch from
520 >    the database. To get total query cost after open, call the "Last" method
521 >    and then GetPerfStatistics.
522 >
523 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
524 >
525 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
526 >    in parenthesises.
527 >
528 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
529 >    SQL identifiers are always delimited by double quotes. If false, then they are
530 >    only delimited if the identifier is a reserved word, contains lower case or special
531 >    characters. Set this property to true to retain previous behaviour.
532 >
533 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
534 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
535 >
536 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
537 >       property MasterDetailDelay: integer {defaults to zero}
538 >
539 >    When non-zero and the dataset is a detail table referencing a master table
540 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
541 >    then a synchronisation delay is added (in milliseconds) between the master
542 >    row changing and the detail dataset being re-opened. If the master dataset
543 >    is scrolled before the delay expires then the delay is reset. This can be used
544 >    to avoid performance overheads when scrolling through a large master dataset.
545 >
546 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
547 >    chreads unit must be included in your project. TTimer is not used in order
548 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
549 >
550 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
551 >    with Extract Option eoDatabase.
552 >
553 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
554 >    When a deLayoutChanged event is reported on the ListSource dataset, the
555 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
556 >    relationship with the control's datasource (master).
557 >
558 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
559 >
560 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
561 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
562 >
563 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
564 >    DDL (Firebird 3 and later only).
565 >
566 > 22. TIBLookupComboBox Autocomplete Fixes:
567 >    i. Only appended text is now selected after autocomplete.
568 >    ii. Uppercase keys no longer ignored for autocomplete.
569 >    iii. Retain Prefix case is now honoured correctly.
570 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
571 >        before autocomplete performed. i.e. behaviour now the same as when
572 >        no DataSource assigned.
573 >
574 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
575 >    between SQL statements.
576 >
577 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
578 >    ObjectNames are converted to upper case before matching against metadata object
579 >    names, unless the objectname is delimited by double quotes, in which case, the
580 >    double quotes are removed and the remaining string is used (unmodified) to match
581 >    against the metadata object name.
582 >
583 >    If true then the ObjectName is used as is without modification and matched
584 >    against the metadata object name. No attempt is made to remove double quotes.
585 >
586 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
587 >    with eoTrigger, these extract types can be used to select only Database Triggers,
588 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
589 >
590 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
591 >    statement separate character is now reset to the default (';').
592 >
593 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
594 >
595 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
596 >    a commit or reconnect statement and instead activated only when next SQL statement
597 >    is executed.
598 >
599 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
600 >
601 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
602 >    converting statement to upper case.
603 >
604 > 31. TIBExtract: metadata comments now supported. New published property
605 >    IncludeMetaDataComments (default true). If true then metadata comments included
606 >    in extracted DDL. New Extract Object member eoComments. This may be used with
607 >    ExtractObject method to list all metadata comments.
608 >
609 > 32. TIBExtract: ListObjectNames method added.
610 >
611 > 33. Updated Database component editor to support additional connection string
612 >    types.
613 >
614 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
615 >
616 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
617 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
618 > RELEASE.
619 >
620 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
621 >
622 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
623 >
624 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
625 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
626 >   information). However, this is also a very useful mechanism for returning updated computed by
627 >   column values. Values returned as a result of executing an Insert or Update statement
628 >   replace existing values in the current row for each corresponding column.
629 >
630 >   Previously, if a dataset's select query included read only (computed by) fields then
631 >   an automatic row refresh was performed after an insert or update query had been processed,
632 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
633 >   that an automatic refresh is no longer performed if an insert or update query contains
634 >   a returning clause that updates one or more fields on the current row. A full row
635 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
636 >   field values and the select query contains read only fields. Use of Insert/update
637 >   returning should be significantly more efficient than executing a refresh query.
638 >
639 >   This behaviour change is intended to be backwards compatible and there should be no need to change
640 >   existing programs, other than to improve performance by using the new capability.
641 >
642 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
643 >   they are called when the dataset row is being deleted, there is no value in
644 >   updating the current record from the query result. Instead, a new event handler
645 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
646 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
647 >   by the query. The event handler can then interrogate the query results and
648 >   perform whatever action is necessary. For example to confirm, to the user,
649 >   the deletion of a row with the returned values.
650 >
651 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
652 >   any Computed By or Identity Columns. The IBTables example has been updated to
653 >   illustrate the computation of the employee Full Name on update.
654 >
655 > 5. TIBTable: The GeneratorField property is now published.
656 >
657 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
658 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
659 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
660 >   each Identity column after the insert is executed.
661 >
662 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
663 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
664 >   Insert..Returning clause.
665 >
666 > 8. TIBGenerator: small performance improvement by not preparing query each time
667 >   a new value is generated.
668 >
669 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
670 >
671 > 10. Property editors will now sync table name to a System Table when "Include System
672 >    Tables" is selected and the query is for a System Table.
673 >
674 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
675 >    values are no longer converted to milliseconds from TDateTime and then back again
676 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
677 >
678 > 12. Property Editors handling of Stored Procedures.
679 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
680 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
681 >      query).
682 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
683 >
684 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
685 >    can be used to select a package. If non-empty, the stored procedure name is
686 >    expected to be a stored procedure defined in the specified package and the
687 >    generated SQL will be as required for a stored procedure located in a package.
688 >
689 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
690 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
691 >    which a stored procedure can be selected. With no package name selected, non-package
692 >    stored procedures are listed.
693 >
694 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
695 >    for password on reconnect.
696 >
697 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
698 >    and character set name.
699 >
700 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
701 >    DB info lookups"
702 >
703 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
704 >
705 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
706 >
707 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
708 >    parameters. This stops an exception being raised when the field cannot be
709 >    located in the record buffer.
710 >
711 > 21. Property Editors now automatically include System Tables when opened and when the query table
712 >    is a System Table.
713 >
714 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
715 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
716 >
717 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
718 >    add the SPB item isc_spb_expected_db. This names a database using
719 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
720 >    database. examples/services re-written to illustrate use of "expected_db".
721 >
722 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
723 >    This avoids truncated backups when the server returns a timeout (busy) response.
724 >
725 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
726 >
727 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
728 >    databasenames. These are respectively expanded to the local system's temp directory
729 >    (including trailing delimiter) or to a prescribed data directory (including
730 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
731 >    in the user's home directory. The hidden directory name is either the string returned
732 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
733 >    Under Windows, the directory is the same as the Data Directory as decribed
734 >    above but instead prefixed by the User's application data path. These may be
735 >    used to improve application portability for Personal Databases.
736 >
737 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
738 >    this has not worked for a long time and is not useful either. FieldDefs should be
739 >    managed using the Fields Editor as with any other dataset. To access the fields
740 >    editor for a TIBTable component, double click on the component. The fields editor
741 >    is then displayed.
742 >
743 > 28. TIBDatabaseInfo: new properties/function
744 >     * DateDBCreated (returns date/time database created)
745 >     * TransactionCount (returns no. of active transactions)
746 >     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
747 >     * PagesFree (Firebird 3 or later)
748 >     * PagesUsed (Firebird 3 or later)
749 >     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
750 >     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
751 >
752 > 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
753 >
754 > 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
755 >
756 > 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
757 >    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
758 >
759 > 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
760 >    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
761 >    firing during backup and restore.
762 >
763 > 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
764 >    for verbose output using the new property "StatisticsRequested".
765 >    see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
766 >
767 > 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
768 >
769 > 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
770 >    palette. This uses the online validation feature added in Firebird 2.5. The
771 >    services's properties enable inclusion/exclusion of tables and indexes using
772 >    regular expressions. See.
773 >    https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
774 >
775 > 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
776 >    option on a database.
777 >
778 > 37. TIBCustomService: Assign method implemented to allow copying of service login
779 >    context between service API components. "Detach" method now only detaches
780 >    service when last reference to the service interface detaches. Tidy up of
781 >    code for SetActive and Attach methods including password hiding.
782 >
783 > 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
784 >    and used to determine the auth method and protocol used for the connection.
785 >
786 > 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
787 >    a Create Database Statement generated by IBX.
788 >
789 > 40. All IBServices now have an additional published property "PortNo". This may
790 >    be set to a non-standard port number when necessary. If zero then the default
791 >    port number is used.
792 >
793 > 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
794 >    and not just the mouse.
795 >
796 > 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
797 >
798 > 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
799 >    image index and selected image index for each node to be set from a database field.
800 >
801 > 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
802 >    then database schema includes grants to all users. If not present then the
803 >    only user grants included are those to User PUBLIC.
804 >
805 > 45. TIBTreeView: performance improvement. When expanding include both expanded node
806 >    and child nodes in dataset.
807 >
808 >
809 > IBX Change Log  version                            (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
810 >
811 > 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
812 >   changes.
813 >
814 > 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
815 >   Bug could result in truncated multi-byte character set values.
816 >
817 > 3. Changes consequential on moving fbintf character set utility functions from
818 >   IFirebirdAPI to IAttachment.
819 >
820 > 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
821 >
822 > 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
823 >   results in autocomplete ignoring prefix text.
824 >
825 > 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
826 >   entering a new name into the text box.
827 >
828 > 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
829 >   Firebird rather than recomputing it.
830 >
831 > 8. Property Editor positioning tidy up: All IBX Property editors should now be
832 >   screen centre. Previously some were "poDesigned" which may be inappropriate
833 >   for multi monitor desktops.
834 >
835 > 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
836 >
837 > 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
838 >    a transaction and always reset the object.
839 >
840 > 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
841 >
842 > 13. TIBXScript: Allow for override of database filename in Create Database statements.
843 >
844 > 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
845 >    to a gbak format archive.
846 >
847 > 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
848 >
849 > 16. IBLocaldb: Drop database if error creating an empty database.
850 >
851 > 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
852 >    unless selected node not in current dataset.
853 >
854 > 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
855 >    to TIBCustomService, and IBlocalDB code tidy up.
856 >
857 > 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
858 >    behaviour due to uninitialised variable.
859 >
860 > 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
861 >    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
862 >
863 > 21. IBSQL: When Database changed ensure that all resources are freed.
864 >
865 > 22. IBCustomDataset: When database changed ensure that queries an unprepared.
866 >
867 > 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
868 >    * Line Wrap on SQL Token boundaries (on user command)
869 >    * auto-complete table names in drop down list of table names
870 >    * Double click on tablename or field name adds to SQL text
871 >
872 > 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
873 >
874 > 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
875 >    TVariantArray. Seems to avoid memory corruption in Windows (probably a
876 >    workaround for a problem in fpc 3.0.4 win64).
877 >
878 > 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.

884 > 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
885 >   include remote system name.
886 >
887 > 2. TIBExtract: No longer include comment header and COMMIT statement for empty
888 >   tables when data included in output.
889 >
890 > 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
891 >   and timing information to be written to stdout. This may be used to locate
892 >   performance bottlenecks.
893 >
894 > 4. SQLParser: only call "OnChanging" event handler when value is different.
895 >
896 > 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
897 >
898 > 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
899 >   that BindFields is called when the query is next activated. Avoids FieldName
900 >   not found error.
901 >
902 > 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
903 >   purpose and allows the programmer to define any action they want for Update, Insert
904 >   or Delete. This may be complex SQL (similar to a Trigger), application specific
905 >   filtering of updates, or use of statements such as Grant or Revoke instead of
906 >   normal DML. See User Manual for more information.

910 > 1. TIBEvents: Fix uninitialised variable that could result in lost events.
911 >
912 > 2. TIBExtract: Added support for FB3 "USAGE" privilege.
913 >
914 > 3. TIBExtract: data formatted as Charset set "octets" is now output using

916 >
917 > 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
918 >   using a simple XML format.
919 >
920 > 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
921 >   grants to these objects.
922 >
923 > 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
924 >   dependency problems restoring complex databases.
925 >
926 > 7. TIBXScript: This component has been restructured to allow for the processing of
927 >   embedded XML in INSERT statements and to support interactive sources in addition
928 >   to non-interactive data sources such as files.
929 >
930 > 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
931 >
932 > 9. TIBXScript: ISQL compatiable Set statements are now supported:
933 >   SET SQL DIALECT
934 >   SET TERM
935 >   SET AUTODDL
936 >   SET BAIL
937 >   SET ECHO
938 >   SET COUNT

940 >   SET NAMES <character set>
941 >
942 > 10. IBVersion unit added to hold current IBX Version Number information.
943 >
944 > 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
945 >    and domain definitions.
946 >
947 > 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
948 >    fully supported.
949 >
950 > 13. TIBExtract: when a database dump includes data, the generator values are now also set.
951 >
952 > 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.

955 >
956 > See also doc/IBX4LazarusGuide.pdf for important information on
957 > upgrading to IBX2.
958 >
959 > 1. Size property of TIBStringField is now the width in characters of the field
960 >   and not the byte length. This applies only to multi-byte character sets such
961 >   as UTF8. The original approach aligned with TStringField. However, the TStringField
962 >   code is not recognised as a bug and hence this change to align the behaviour.
963 >   The TStringField change is expected in fpc 3.2.0.
964 >
965 > 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
966 >   true (default) then Size property value saved in the lfm is ignored. Size is
967 >   always set from the dynamic information read from the database. It is unclear
968 >   why anyone would want to override this and set Size to false.
969 >
970 > 3. ibxscript: should now handle correctly a Case..End statement within a procedure
971 >   block.
972 >
973 > 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
974 >   exist when an attempt is made to connect to it (run time only) then an attempt
975 >   is made to create the database.
976 >
977 > 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
978 >   has been successfully created as a result of a call to CreateDatabase or when
979 >   creating a database after it was found not to exist.
980 >
981 > 6.  DBControlGrid: a race condition could result in the wrong row image being
982 >    written to the cache. This has been avoided by a trip round the message
983 >    loop before rendering the row image.
984 >
985 > 7.  DBControlGrid: It is strongly recommended not to open the source DataSet for
986 >    a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
987 >    known to risk corrupt rendering of row images when the control is first
988 >    displayed. If necessary use "Application.QueueAsyncCall" to delay opening
989 >    of the dataset (see DBControlGrid examples) until the Form's Window has been created.
990 >
991 > 8.  DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
992 >    a TDateEdit control located on an editor panel.
993 >
994 > 9.  TIBExtract: brought up-to-date plus many bug fixes.
995 >
996 > 10. DBControlGrid: Removed memory leak when updating rows.
997 >
998 > 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.

1002 > 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
1003 >   when target codepage is CP_NONE. This is a workaround for
1004 >   http://bugs.freepascal.org/view.php?id=30622.
1005 >
1006 > 2. DBLog option removed from TIBStatisticalService - not supported by server
1007 >   since Firebird 1.5.
1008 >
1009 > 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1010 >   similar.
1011 >
1012 > 4. IBCodePage: updated mapping between codepages and character id.
1013 >
1014 > 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1015 >   Firebird. Character sets with a char width of two are not UTF16.
1016 >
1017 > 6. Strings received from the database are now always transliterated into UTF8
1018 >   regardless of the database character set or connection character set. This

1022 >
1023 > 1. IBBlob: Defer reading of blob until read method called. This avoids having to
1024 >   read in an entire blob just to get the size of the blob. General performance
1025 >   improvement when opening datasets containing blobs.
1026 >
1027 > 2. Clearing a  Blob now sets the corresponding field's modified flag.
1028 >
1029 > 3. IBLookupCombo: When not performing auto-complete, original query sort order
1030 >   is now used.
1031 >
1032 > 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1033 >   determined.
1034 >
1035 > 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1036 >
1037 > 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1038 >   lazarus 1.6.0

1044 >
1045 > 1. No character set specified for connection: when a text blob is retrieved, the
1046 >  character set is determined by looking up the native character set using then
1047 >  Firebird API. Otherwise a text mode blob is assumed to have the same character
1048 >  set as the connection.
1049 >
1050 > 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1051 >   for Login Dialog returing a change to the database path.
1052 >
1053 > 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1054 >   to be changed from that given in the TIBDatabase/TIBServer component and for the
1055 >   entered value to be saved on a project specific basis (design time only).
1056 >
1057 > 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1058 >   column fieldname. If they are the same then it is acts as a look up for the KeyValue
1059 >   Otherwise, it sets the column text to the selected ListField Value.
1060 >
1061 > 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1062 >   column width.
1063 >
1064 > 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1065 >   and a case insensitive search is requested.
1066 >
1067 > 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1068 >   or column ListSource.
1069 >
1070 > 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1071 >   unprepare) when closing and the text has not changed.
1072 >
1073 > 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1074 >   Less likely to cause a cursor re-use error on Windows.
1075 >
1076 > 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1077 >   Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1078 >
1079 > 11. TIBTreeView: Guard against nil destination on record changed
1080 >
1081 > 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1082 >    string type with the code page set to reflect the returned field encoding after
1083 >    Firebird driver transliteration, if any.  FPC 3.0.0 onwards only. Behaviour unchanged for
1084 >    earlier versions.
1085 >
1086 > 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1087 >    will now result in transliteration to the code page specified for the Firebird driver
1088 >    if the assigned string has a different code page. FPC 3.0.0 onwards only.
1089 >
1090 > 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1091 >    is ignored and the lc_ctype value, when the database is opened, is set to align with
1092 >    the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1093 >    platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1094 >    3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1095 >    the GETACP is used to determine the Windows code page.
1096 >
1097 > 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1098 >    name used as the lc_ctype when the database was opened. Only valid while the
1099 >    Database is connected.
1100 >
1101 > 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage

1106 > 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1107 >   path is given and database attach fails due to access permission issues on the
1108 >   temp directory or security database, then the attach is retried with "localhost:"
1109 >   prefixing the databasename. This should avoid problems when the database has to
1110 >   be accessed by a local (e.g. classic) server and libfbembed is used.
1111 >
1112 > 2. Windows: revised search order for Firebird DLL:
1113 >     i.   The Firebird Embedded Server in the application Directory.
1114 >     ii.  If the FIREBIRD environment variable is set then the directory this
1115 >          points to is searched for the FB Client DLL and then then underlying
1116 >          "bin" directory.
1117 >     iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1118 >          is used to locate the Firebird installation directory and the underlying
1119 >          "bin" directory is searched for the FB Client DLL.
1120 >     iv.  The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1121 >          are searched for the FB Client DLL.
1122 >     v.   The PATH Environment variable is used to search for the FB Client DLL.
1123 >     vi.  Finally the  PATH Environment variable is used to search for IBASE.DLL.
1124 >
1125 > 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1126 >   See doc/readme.scriptengine and example applications.
1127 >
1128 > 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to

1130 >   See dpc/readme.localdatabase and example applications.
1131 >
1132 > 5. IBDynamicGrid: Reordering on column header click should now also work for
1133 >   dynamic columns.
1134 >
1135 > 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1136 >   between incrementing/decrementing the lock count and signalling the event.

1141 >
1142 > 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1143 >
1144 > 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1145 >
1146 > 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1147 >
1148 > 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1149 >   i.e. when it is a calculated field
1150 >
1151 > 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1152 >   This problem was due to a race condition between recalculating row heights and
1153 >   determining which row was selected by the mouse click. The row height calculation
1154 >   is now deferred by an extra trip round the message loop allowing the row to
1155 >   be always calculated on the current grid layout rather than risking it being
1156 >   calculated on the grid layout after the expanded row has been shrunk.
1157 >
1158 > 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1159 >   Windows.
1160 >
1161 > 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1162 >   These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1163 >   to be determined at runtime. See doc/readme.charactersets.html.
1164 >
1165 > 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1166 >   TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1167 >
1168 > 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1169 >   TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1170 >   1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1171 >
1172 >   Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1173 >   from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1174 >   implies no truncation.
1175 >
1176 > 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1177 >
1178 > 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1179 >   (avoids "Not in Edit Mode" error).
1180 >
1181 > 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1182 >
1183 > 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1184 >    DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1185 >
1186 > 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1187 >
1188 > 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1189 >
1190 > 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1191 >
1192 > 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.

1196 > 1.   OnCloseUp Event Handler added to TDBLookupProperties
1197 >
1198 > 2.   IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1199 >     problem with row size when exception is called.
1200 >
1201 > 3.   IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1202 >
1203 > 4.   IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1204 >     in a TCustomComboBox and ignores return key if in a TCustomMemo
1205 >
1206 > 5.   IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1207 >     keyed in i.e. when autocomplete not performed
1208 >
1209 > 6.   Cleanup of "Uses" clauses and add console mode support. IBX should now support
1210 >     console mode applications with all LCL required functions (builtin dialogs and
1211 >     cursor management) centralised in the  IBDialogs unit. As long as "IBDialogs" is
1212 >     not included in your project, IBX should compile and link with a console mode program.
1213 >     See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1214 >     console mode application or the IDE will automatically assume that your
1215 >     application is GUI based. Instead, you should include the ibexpressconsolemode package.
1216 >
1217 >     IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1218 >     to use the built in dialogs and cursor management. IBDialogs is
1219 >     included by default if "ibexpress" is in your project source's "uses" clause.
1220 >     This should be the case for all projects created through the IDE. This is why
1221 >     you do not want to add the ibexpress package to console mode applications. The
1222 >     ibexpressconsolemode package has been created to allow console mode programs
1223 >     to avoid adding LCL dependencies when using IBX, while still having the
1224 >     unit search paths set up correctly.
1225 >
1226 >     Existing users should check to ensure that the "ibexpress" unit is included in
1227 >     each project's source file (*.lpr).
1228 >
1229 >     You may find that in order for the IDE to recognise that ibexpressconsolemode
1230 >     exists, you have to first open the package in the IDE and then close it. This
1231 >     adds it to the most recently accessed packages list. To make it permanently
1232 >     available, add the package name to lazarus' staticpackages.inc file.
1233 >
1234 >         Thanks to Julio Jiménez for suggesting support of console mode.
1235 >
1236 > 7.   SQL Parser can now accept quoted strings that include new lines
1237 >
1238 > 8.   IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1239 >     of text on start of edit. This is particularly useful when tabbing to a
1240 >     column and then inserting text.
1241 >
1242 > 9.   New Examples provided for IB Services and ISQLMonitor.
1243 >
1244 > 10. Fix error when writing to blob streams that recorded only the last buffer
1245 >    write in the blob stream. In most cases, this did not cause a problem as the
1246 >    IB Blob Stream is written in a single write. However, with the TDBImage, write
1247 >    of a graphic type prefix was lost which caused a problem when the image could
1248 >        not be automatically recognised.
1249 >
1250 > 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1251 >    already open" errors due to random numbers used for the cursor name being identical.
1252 >
1253 > 12. IBTable: corrected error that could result in an "Index out of bounds" error
1254 >    when opening the table and the Primary Key is the last or only column in the
1255 >    table. Thanks to Rick Hoover for the fix.

1257 > 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1258 >    of "UTF-8", and update list of available database character sets. Existing
1259 >    users should check the current lc_ctype setting in their applications.

1261 > IBX Change Log  version  (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1262 >
1263 > 1.  Firebird Services: avoid List Index error when opening a service with an
1264 >    empty Params property.
1265 >
1266 > 2.  IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1267 >    Link now set up in Loaded method - avoids occasional failure to apply
1268 >    SQL markup on initial open.
1269 >
1270 > 3.  "Employees" example performance improvements when scrolling.
1271 >
1272 > 4.  DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1273 >    TFrame. Force recaching of selected frame to avoid GTK race (results in a
1274 >    random image cached).
1275 >
1276 > 5.  DBControlGrid: Should now react to changes in panel height at run time.
1277 >
1278 > 6.  IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid  
1279 >    even when further rows exist.
1280 >
1281 > 7.  DBControlGrid: DefaultRowHeight is no longer a published property as it should
1282 >    always be derived from panel height and setting this property can cause confusion.
1283 >    Note for existing projects: to avoid a missing property error at run time,
1284 >    each form using the DBControlGrid must be opened, updated and saved in the IDE
1285 >    in order to remove the property value from the lfm.
1286 >
1287 >
1288 > IBX Change Log  version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1289 >
1290 > 1.  TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1291 >    call Prepare before setting parameter values.
1292 >
1293 > 2.  Error message on ParamByName (all cases) not found now includes name of missing parameter.
1294 >
1295 > 3.  Code tidyup and more robust handling of dsql information result vector.
1296 >
1297 > 4.  Support for centralised handling of transaction status changes. TIBTransaction
1298 >    has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1299 >    and "AfterExecQuery". The first three are called after the same event is called
1300 >    for an IBCustomDataSet descendent using the Transaction. The fourth is called
1301 >    after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1302 >    enable monitoring of transaction status changes for a given transaction to be
1303 >    handled in a single place. For example, when a change to the dataset occurs
1304 >    an indicator can be set that shows the user that in order to save changes,
1305 >    the transaction should be committed.  Rather than doing this per dataset, this
1306 >    can now be done per transaction.
1307 >
1308 > 5.  TDataSet.CheckBrowseMode automatically posts changes to the current row when
1309 >    the dataset is scrolled. However, any changes to the current row are, by default,
1310 >    discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1311 >    have a new property "DataSetCloseAction" that adds automatic posting of changes
1312 >    on dataset close. If this property is set to dcDiscardChanges (default) then the
1313 >    behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1314 >    then IBX will attempt to post any unsaved changes before the dataset is closed
1315 >    (and after the BeforeClose event handler is called). The exception is when the
1316 >    dataset is being closed as a result of a transaction rollback. In this case,
1317 >    no action is taken and any unsaved  changes are discarded. This avoids both
1318 >    unnecessary overhead and the risk that a validation error may occur in the Post
1319 >    raising an exception and thereby preventing a rollback.
1320 >
1321 > 6.  String Field sizes and Display Widths should now be correct for multi-byte character sets.
1322 >    In earlier versions, the Display Width was set to the maximum byte width rather than the character
1323 >    width. Display Widths are now corrected by dividing by the max byte width per character.
1324 >    For UTF8 character sets, the byte width is four and hence the Display Width will be
1325 >    the byte width divided by 4. The byte width of each character set is determined
1326 >    dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1327 >    system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1328 >
1329 > 7.  SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1330 >
1331 > 8.  IBLookupComboEditBox: List should now always be restored to full list when the
1332 >    control loses focus. Default Key press default interval reduced to 200ms.
1333 >
1334 > 9.  DBControlGrid: Ensure that selection is changed to newly appended row, even
1335 >    when dataset rows are less than visible rows.
1336 >
1337 > 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1338 >    does not exist or DataSet is empty. More responsive on dataset open. New event
1339 >    OnRestorePosition. Column sort disabled if no header row.
1340 >
1341 > 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1342 >    while dataset state is dsInsert. Avoids posting errors.
1343 >
1344 > 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1345 >    avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1346 >
1347 > 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1348 >
1349 > 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1350 >    to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1351 >    a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1352 >    always "posts" the current record regardless or whether or not it may be more appropriate
1353 >    to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1354 >    "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1355 >    as the first action of the "Post" method and allows the handler to convert the Post
1356 >    into a Cancel if that is the appropriate action on moving to a different row. This is
1357 >    achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1358 >    raised here, but it may still be more appropriate to validate a post and signal
1359 >    a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1360 >
1361 > 15. On Unix derived systems, the Firebird library name can now be given as a colon
1362 >    separated list. Each library name on the list is tried in turn, in left to right
1363 >    order with the first found being used as the firebird library. By default, on Linux,
1364 >    the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1365 >    overidden by the FBLIB environment variable or the OnGetLibraryName function.
1366 >
1367 >    Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1368 >    then it will still attempt to access the database via the Firebird Server and will
1369 >    require a username and password. If only the pathname is given, then the username
1370 >    and password should be omitted and the unix file permissions are used to grant
1371 >    access.
1372 >
1373 > IBX Change Log  version  (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1374 >
1375 > 1.  A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1376 >    rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1377 >    that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1378 >    corresponds to a row of the linked DataSource. Any data aware control on the
1379 >    replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1380 >
1381 > 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1382 >   When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1383 >   takes place during database access. This may be useful when there are performance issues with
1384 >   the change of cursor. Setting the property to false suppresses the change of cursor.
1385 >
1386 > 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1387 >   and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1388 >   Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1389 >   making all changes permanent immediately rather than when the transaction is explicitly
1390 >   committed.
1391 >
1392 > 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1393 >   using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1400 >
1401 > 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1402 >   This is typically used during an "OnBeforeOpen" event handler to manipulate the
1403 >   "Where" and "Having" clauses to implement user specified filters of arbitrary
1404 >   complexity.
1405 >
1406 > 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1407 >   three new data aware controls dependent on IBX and which make use of the SQL Parser.
1408 >   These are:
1409 >
1410 >   - TIBLookupComboEditBox
1411 >   - TIBDynamicGrid
1412 >   - TIBTreeview
1413 >
1414 >   TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1415 >   of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1416 >   to revise the available list and restrict it to items that are prefixed by the
1417 >   typed text (either case sensitive or case insensitive). Autoinsert allows a
1418 >   newly typed entry to be added to the list dataset and included in the available
1419 >   list items.
1420 >
1421 >   TIBDynamicGrid is a TDBGrid descendent that provides for:
1422 >   - automatic resizing of selected columns to fill the available row length
1423 >   - automatic positioning and sizing of a "totals" control, typically at the
1424 >     column footer, on a per column basis.
1425 >   - DataSet resorting on header row click, sorting the dataset by the selected column.
1426 >     A second click on the same header cell reversed the sort order.
1427 >   - Support for a "Panel Editor". That is on clicking the indicator column, the row
1428 >     is automatically expanded and a panel superimposed on it. The panel can have any
1429 >     number of child controls, typically data aware controls with the same datasource
1430 >     as the grid allowing for editing of additional fields and more complex editors.
1431 >   - Reselection of the same row following resorting.
1432 >   - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1433 >     Its properties are specified on a per column basis and allows for one or more
1434 >     columns to have their values selected from a list provided by a dataset.
1435 >     Autocomplete and autoinsert are also available. The existing picklist editor
1436 >     is unaffected by the extension.
1437 >
1438 >   TIBTreeView is a data aware TCustomTreeView.
1439 >
1440 > 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1441 >   zero scale will no longer return an error. An Int64 will be returned instead.
1442 >
1443 > 4. TIBTransaction now has events for Before and After Transaction End and a new function
1444 >   "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1445 >
1446 > 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1447 >   repeated multiple times.
1448 >
1449 > 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1450 >   check used to get in the way of using Stored Procedures, and "Update or Insert"
1451 >   statements.
1452 >
1453 > 7. Insert, Modify and Delete property Editors now support Query Generation from
1454 >   Stored Procedures.
1455 >
1456 > 8. Three new examples illustrate the use of the new IB Controls
1457 >
