16 > IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
17 >
18 > NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
19 >      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
20 >      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
21 >      ISSUES TO support@mwasoftware.co.uk
22 >
23 > 1. Complete rewrite of internal buffer management in order to improve performance
24 >   and maintainability. Highlights:
25 >
26 >   * Extending the size of the buffer pool no longer has to copy the entire record
27 >     cache. Instead, a new extent is simply added to the buffer pool.
28 >   * A memory to memory copy of each display buffer now is avoided when scolling the
29 >     dataset.
30 >   * A separate set of buffers is now used for calculated fields. This avoids
31 >     having to keep copies of calculated field values in the buffer cache.
32 >   * Compact bitmaps are used to record null status and need to refresh in each
33 >     buffer.
34 >   * Display buffer type changed from PChar to TRecordBuffer in line with change of
35 >     buffer type in FCL-DB.
36 >
37 > 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
38 >   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
39 >
40 > 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
41 >   If either or both of these flags are set at design time (using the fields editor)
42 >   then this forces a row refresh on respectively insert or update, or both, when the
43 >   corresponding field is not present in an SQL RETURNING clause.
44 >
45 > 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
46 >   maintainability and readability and to add identification of primary key fields.
47 >
48 > 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
49 >   as a refresh of the current row. However, this is different behaviour to that described
50 >   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
51 >   the dataset from the underlying database, and attempts to reposition the cursor on
52 >   the same record as it was". IBX now complies with the FPC definition of Refresh.
53 >
54 > 6. A progammatic Row Refresh should no longer be required.
55 >   Use Insert/Update... returning to refresh any fields that may change following an
56 >   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
57 >   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
58 >   for the field at Design Time to force a row refresh if not in the returning clause.
59 >
60 > 7. It should now be possible to insert a row into an empty unidirectional dataset.
61 >
62 > 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
63 >   This gives the number of buffers in the initial block for the buffer pool in
64 >   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
65 >   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
66 >   for small datasets.
67 >
68 > IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
69 >
70 > 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
71 >
72 > 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
73 >
74 > 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
75 >
76 > IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
77 >
78 > 1. TIBTransaction: new properties
79 >    property TransactionID: integer read GetTransactionID;
80 >    property IsReadOnly: boolean read GetIsReadOnly;
81 >    {published}
82 >    property TransactionName: string read FTransactionName write SetTransactionName;
83 >
84 > 2. IBCustomDataset: per row blob and array buffer cached clear before processing
85 >   Insert or Update...Returning. This allows blobs and arrays to be returned
86 >   by the statement.
87 >
88 > 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
89 >
90 > 4. TransactionName initialised to a newly generated GUID if empty.
91 >
92 > 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
93 >   for the fbintf package's journaling capability. TIBJournal is used to set the
94 >   file path and filename for the journal file and to Enabled (start journaling) and
95 >   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
96 >   more information, and comments in IBJournal.pas.
97 >
98 > 6. TIBDatabase.InternalTransaction is now a read only transaction.
99 >
100 > 7. Bug fix: blob id no longer set to null on update when blob has not been
101 >   retrieved.
102 >
103 > 8. Row auto refreshed on update/insert if blob or array field updated and field
104 >   not in a returning clause.
105 >
106 > 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
107 >   buffer overhead and avoids problem when refresh query has a different column
108 >   count to select query i.e. incorrectly changing number of columns.
109 >
110 > 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
111 >
112 > 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
113 >    string. Note that the Version property returns an InterBase compatible version string.
114 >
115 > 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
116 >
117 > IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
118 >
119 > 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
120 >   This is for compatibility with Firebird 5 where Update...Returning can return
121 >   a cursor.
122 >
123 > IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
124 >
125 > 1. Add try-..except check when initially loading library in IDE. This should
126 > ensure that IDE continues to load even when a failure occurs in IBX load
127 > library.
128 >
129 > 2. IBXScript: now recognises a CASE...END block within a stored procedure and
130 >   hence will correctly detect end of the outer containing block when the block
131 >   contains a SELECT ... CASE ... END construct.
132 >
133 > 3. IBExtract: some further tidying up to remove extraneous white space.
134 >
135 > 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
136 >   errors when extra elements are added to DB.TFieldType.
137 >
138 > 5. IBUpdate: updated to reflect changes to ISQLParam.
139 >
140 > 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
141 >
142 > 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
143 >
144 > 8. IBSQL: Support for scrollable cursors added (note: local databases only)
145 >
146 > IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
147 >
148 > 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
149 >   exception of those defined to be one byte wide e.g. DBImplementationNo.
150 >
151 > 2. TIBSQL: Batch Update/Insert support added.
152 >
153 > 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
154 >   is no longer automatically converted to upper case when it is syntactically a
155 >   SQL Identifier. This is to support the use of stored procedures defined e.g.
156 >   as CREATE PROCEDURE "iCASE".
157 >
158 >   There could be a backwards compatibility issue when the StoredProcName was entered
159 >   manually at design time. That is not selected from the drop down list. If the
160 >   StoredProcName is entered in mixed case and the procedure was declared e.g. as
161 >   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
162 >   ensure that the value of the StoredProcName is all upper case, unless it was
163 >   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
164 >   quotes).
165 >
166 >   Note that when a stored procedure name was declared delimited in double quotes,
167 >   as in the first example above, the value of the StoredProcName property must not
168 >   include the delimiters (double quotes).
169 >
170 > 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
171 >   upgrade.conf was not found. This replaces silently ignoring the problem.
172 >
173 > 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
174 >   'Version.%.3d' and is used to generate the section header names (for a given
175 >   version no.) in the upgrade.conf file.
176 >
177 > IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
178 >
179 > 1. -c command line option added to fbsql example program. Used to set connection
180 >   character set.
181 >
182 > IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
183 >
184 > 1. Firebird 4 support added.
185 >
186 > 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
187 >   extended precision NUMERIC fields are supported.
188 >
189 > 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
190 >
191 > 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
192 >   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
193 >
194 > 5. IBExtract now supports FB4 enhancements:
195 >   - new data types as above
196 >   - Identity column extensions
197 >   - Default user role
198 >   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
199 >   - Internal Functions
200 >
201 > 6. IBExtract: new event: OnExtractLines.
202 >
203 > 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
204 >
205 > 8. IBXServices: Server version no. parsing now allows any letter before major version number
206 >   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
207 >
208 > 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
209 >   format for rendering a time zone.
210 >
211 > 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
212 >     to convert TIME WITH TIME ZONE data type values to and from GMT.
213 >
214 > 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
215 >    IIBGUIInterface and IIBTimerInf respectively.
216 >
217 > 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
218 >    now accessible as properties of TIBDatabase and TIBTransaction respectively.
219 >
220 > 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
221 >    truncated to its fixed character width rather than being right padded with
222 >    white space to the maximum data size.
223 >
224 > 14. TIBTable.Empty table. In additional to deleting all records in the underlying
225 >    table, the internal buffers are now also flushed ensuring that the TIBTable is
226 >    also empty.
227 >
228 > 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
229 >
230 > 16. TIBXControlService descendents: DatabaseName may now be set using a database
231 >    connect string. The database name is extracted from the connect string.
232 >
233 > 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
234 >
235 > 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
236 >
237 > 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
238 >    not being present as required.
239 >
240 > 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
241 >    version that can be customised to work with other database drivers.
242 >
243 > 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
244 >    unnecessary CR at end of line on Unix platforms.
245 >
246 > 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
247 >    seconds in order to reduce risk of message loss.
248 >
249 > 23. ISQLMonitor: read and write count statistics now available via:
250 >      property TIBSQLMonitor.ReadCount;
251 >      IIBSQLMonitorHook.GetWriteCount: integer;
252 >
253 > 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
254 >
255 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
256 >
257 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
258 >    number of UTF8 characters exceeds the string size then string is truncated
259 >    to the maximum string size. This is  usually a problem with fixed width columns
260 >    right padded with white space.
261 >
262 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
263 >    If SQLFiltered is set then when a dataset is opened, each line in the
264 >    SQLFilterParams property is assumed to be a SQL condition clause and
265 >    ANDed into the Where clause of the SQL Select statement provided as a
266 >    dataset property. Each such SQL condition thus acts as an additional filter
267 >    on the dataset.
268 >
269 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
270 >    side filters).
271 >
272 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
273 >   text matches complete entry.
274 >
275 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
276 >   dataset are active (avoids risk of access violation if master is inactive)
277 >
278 > 6. TIBEvents: Registered property can now be set at design time even if database not open
279 >
280 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
281 >   This should prevent "spillover" of events between sessions.
282 >
283 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
284 >   This should ensure that the internal buffer is set up correctly and avoids
285 >   a duplicate initial row.
286 >
287 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
288 >   That is, the DataSize should be the field size * character set width. The
289 >   value returned by DataSize is now the same as the Dataset buffer size reserved
290 >   for the field.
291 >
292 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
293 >
294 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
295 >    and vice-versa. This may result in an exception being raised (correctly) for
296 >    older programs when using dataset fields added to a form and the database has been
297 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
298 >    In such cases, the field needs to be deleted in the IDE fields editor and then
299 >    added back in.
300 >
301 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
302 >    false if query contains only white space and not just empty.
303 >
304 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
305 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
306 >    is cancelled.
307 >
308 > 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
309 >    called on a null field.
310 >
311 > 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
312 >    results in an empty dataTC86                Client side Filtered Dataset    1       X
313 > set.
314 >
315 > 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
316 >    a cached update is applied and an exception is raised.
317 >
318 > 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
319 >
320 > 17. Console Mode Local Database support: backup/restore should now work correctly.
321 >
322 > 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
323 >    possible and an exception raised.
324 >
325 > 19. MinimumVersionNo added to Local Database Support. Database will not open if
326 >    below this version no. and upgrade not possible.
327 >
328 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
329 >
330 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
331 >    not SQL Identifiers are now supported.
332 >
333 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
334 >    passed to the Firebird engine for execution.
335 >
336 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
337 >    is made to scroll back.
338 >
339 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
340 >
341 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
342 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
343 >
344 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
345 >   validated. If no match is found in the list of field names and the database has
346 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
347 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
348 >
349 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
350 >   with fpc 3.2.
351 >
352 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
353 >
354 >
355 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
356 >   and is used to override the default settings in the client side "firebird.conf" This
357 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
358 >   Each line of the string list should be a setting in the same format as "firebird.conf".
359 >   For example "WireCompression = true" in order to request wire compression on the client side.
360 >
361 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
362 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
363 >   also require a compatible setting in the server side "firebird.conf". For example
364 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
365 >   compression to be used.
366 >
367 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
368 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
369 >   ibx/examples/dbinfo for examples of how to display this information.
370 >
371 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
372 >   is a "convenience" property. If set the "WireCompression=true" is added to the
373 >   ConfigOverrides. If unchecked then this setting is removed.
374 >
375 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
376 >   not "INT64".
377 >
378 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
379 >   These are:
380 >    property TimestampFormat: string;
381 >    property DateFormat: string;
382 >    property TimeFormat: string;
383 >
384 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
385 >   DATETIME and TIME. The format strings use the standard FPC date/time format
386 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
387 >
388 >   If any of the above properties are set to an empty string, then the locale default
389 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
390 >   locale default is extended by appending '.zzz' to include milliseconds.
391 >
392 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
393 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
394 >
395 > 5. New published property for TIBCSVDataOut:
396 >     property QuoteStrings: boolean (default true)
397 >
398 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
399 >   used to delimit each and every string in the output.
400 >
401 > 6. New published properties for TIBCSVDataOut:
402 >    property FieldSeparator: string;
403 >    property HeaderSeparator: string;
404 >
405 >   Respectively, these provide the separator character(s) used to separate fields
406 >   in data and header rows. Both default to ','.
407 >
408 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
409 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
410 >    property OnFormatTextString;
411 >
412 >   This event handler can be used to process text strings before they are included
413 >   in the output e.g. to replace unprintable characters with alternative strings.
414 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
415 >
416 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
417 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
418 >   and without raising and exception if it does not.
419 >
420 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
421 >   consistency with SQL queries.
422 >
423 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
424 >    When true, SQL statement parameter names are parsed case sensitive. Note for
425 >    TIBDataSet only applies to Select query.
426 >
427 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
428 >    an IDE exception.
429 >
430 > 12. LocalDBSupport: initial database creation should now work correctly
431 >    when the schema source is an sql file.
432 >
433 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
434 >    when defined, this handler will be called by the internal TIBXScript during
435 >    initial database creation when the schema source is an sql file and may be used
436 >    to provide a visual indication of progress in console mode.
437 >
438 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
439 >    to true while a new local database is being created and its schema populated.
440 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
441 >    when the database is disconnected/connected during the create DB procedure.
442 >
443 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
444 >    are now always ignored and replaced by the user name and password provided as
445 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
446 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
447 >    completely ignored if this property is true.
448 >
449 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
450 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
451 >    ImageIndex and SelectImageIndex values on AddNode.
452 >
453 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
454 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
455 >    the same database connection.
456 >
457 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
458 >    if provided, this should be an conditional SQL expression suitable for
459 >    including in an SQL Select statement "where" clause. If non-empty and the
460 >    "Filtered" property is true then the SQL expression provided as the value of
461 >    the "Filter" property is "ANDed" with any existing condition statement
462 >    in the SQL statement's "Where" clause.
463 >
464 >    If the "Filter" property is set at run time, the "Filtered" property is true
465 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
466 >
467 >    The "Filter" condition may include IBX style parameters. In which case, their
468 >    value must be set by the dataset's "OnBeforeOpen" event handler.
469 >
470 >    This is a public property for TIBDataSet and TIBQuery query and intended for
471 >    use at run time.
472 >
473 >    Note: The property is a published property of TIBTable. The TIBTable functionality
474 >    is unaffected by this change.

477 >
478 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
479 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
480 >   mode apps.
481 >
482 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
483 >   statement. This avoids problems if "Execute Block" is used as the Query.
484 >
485 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
486 >   internal SQL tokeniser routines.
487 >
488 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
489 >   as a select statement, with or without CTEs.
490 >
491 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
492 >
493 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
494 >   internal SQL tokeniser routines.
495 >
496 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
497 >    being raised for valid set statements processed by a data formatter.
498 >
499 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
500 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
501 >   the path of the Firebird Library used by the database/services connection.
502 >
503 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
504 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
505 >   services connection.
506 >
507 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
508 >   or param name is not a valid SQL identifier.
509 >
510 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
511 >    view of whether the text box should be editable when no DataSource is specified.
512 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
513 >    ReadOnly is false, the text box is editable when no DataSource is specified.
514 >
515 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
516 >    the FBLIB environment variable. If you do not want to permit this then you
517 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
518 >    this setting.

526 >
527 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
528 > all previous copies of the IBX source code tree before installing this release.
529 >
530 > The IBX packages used by most users have not changed, with one exception. The
531 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
532 > to use the IBServices unit in your applications, please add the iblegacyServices
533 > to the list of dependencies. To do this, open the Project Inspector and select
534 > Add->New Requirement and select "ibLegacyServices" from the list of available
535 > packages.
536 >
537 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
538 >   the IBServices unit providing what is intended to be a clearer and easier to
539 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
540 >   more information and the guide to "Firebird Service Management Using IBX".
541 >   As indicated above, the legacy services components are still available and
542 >   provided in a separate package. There is no need to update working applications
543 >   using the older versions except for an additional package dependency.
544 >
545 > 2. The IBX packages and source code tree have been re-organised in an attempt to
546 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
547 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
548 >   new set of IBX packages.
549 >
550 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
551 >   updated to use the new Services API components.
552 >
553 > 4. The iblocal package has been updated to use the new Services API components.
554 >
555 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
556 >   TIBXSecurityService. It had been wrongly classified in the previous version
557 >   as a per database configuration item. It is global to a server and hence
558 >   correctly positioned as part of the Security Package. In the DBAdmin example,
559 >   the setting has moved to the mappings page.
560 >
561 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
562 >   are ignored.
563 >
564 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
565 >   closed before the database is dropped. Before and After Disconnect event handlers
566 >   are also fired.
567 >
568 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
569 >   is started and not just the first time.
570 >
571 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
572 >   depenendency with comp type.
573 >
574 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
575 >
576 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
577 >    then this is recognised and not ignored.
578 >
579 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
580 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
581 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
582 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
583 >
584 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
585 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
586 >    counters for the select query. Note: stats accumulate after each fetch from
587 >    the database. To get total query cost after open, call the "Last" method
588 >    and then GetPerfStatistics.
589 >
590 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
591 >
592 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
593 >    in parenthesises.
594 >
595 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
596 >    SQL identifiers are always delimited by double quotes. If false, then they are
597 >    only delimited if the identifier is a reserved word, contains lower case or special
598 >    characters. Set this property to true to retain previous behaviour.
599 >
600 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
601 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
602 >
603 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
604 >       property MasterDetailDelay: integer {defaults to zero}
605 >
606 >    When non-zero and the dataset is a detail table referencing a master table
607 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
608 >    then a synchronisation delay is added (in milliseconds) between the master
609 >    row changing and the detail dataset being re-opened. If the master dataset
610 >    is scrolled before the delay expires then the delay is reset. This can be used
611 >    to avoid performance overheads when scrolling through a large master dataset.
612 >
613 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
614 >    chreads unit must be included in your project. TTimer is not used in order
615 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
616 >
617 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
618 >    with Extract Option eoDatabase.
619 >
620 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
621 >    When a deLayoutChanged event is reported on the ListSource dataset, the
622 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
623 >    relationship with the control's datasource (master).
624 >
625 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
626 >
627 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
628 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
629 >
630 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
631 >    DDL (Firebird 3 and later only).
632 >
633 > 22. TIBLookupComboBox Autocomplete Fixes:
634 >    i. Only appended text is now selected after autocomplete.
635 >    ii. Uppercase keys no longer ignored for autocomplete.
636 >    iii. Retain Prefix case is now honoured correctly.
637 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
638 >        before autocomplete performed. i.e. behaviour now the same as when
639 >        no DataSource assigned.
640 >
641 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
642 >    between SQL statements.
643 >
644 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
645 >    ObjectNames are converted to upper case before matching against metadata object
646 >    names, unless the objectname is delimited by double quotes, in which case, the
647 >    double quotes are removed and the remaining string is used (unmodified) to match
648 >    against the metadata object name.
649 >
650 >    If true then the ObjectName is used as is without modification and matched
651 >    against the metadata object name. No attempt is made to remove double quotes.
652 >
653 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
654 >    with eoTrigger, these extract types can be used to select only Database Triggers,
655 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
656 >
657 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
658 >    statement separate character is now reset to the default (';').
659 >
660 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
661 >
662 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
663 >    a commit or reconnect statement and instead activated only when next SQL statement
664 >    is executed.
665 >
666 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
667 >
668 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
669 >    converting statement to upper case.
670 >
671 > 31. TIBExtract: metadata comments now supported. New published property
672 >    IncludeMetaDataComments (default true). If true then metadata comments included
673 >    in extracted DDL. New Extract Object member eoComments. This may be used with
674 >    ExtractObject method to list all metadata comments.
675 >
676 > 32. TIBExtract: ListObjectNames method added.
677 >
678 > 33. Updated Database component editor to support additional connection string
679 >    types.
680 >
681 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
682 >
683 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
684 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
685 > RELEASE.
686 >
687 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
688 >
689 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
690  
691   2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
692     The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
693 <   information). Values returned as a result of executing an Insert or Update statement
694 <   replace existing values in the current row for each corresponding column.
693 >   information). However, this is also a very useful mechanism for returning updated computed by
694 >   column values. Values returned as a result of executing an Insert or Update statement
695 >   replace existing values in the current row for each corresponding column.
696  
697 < 3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
697 >   Previously, if a dataset's select query included read only (computed by) fields then
698 >   an automatic row refresh was performed after an insert or update query had been processed,
699 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
700 >   that an automatic refresh is no longer performed if an insert or update query contains
701 >   a returning clause that updates one or more fields on the current row. A full row
702 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
703 >   field values and the select query contains read only fields. Use of Insert/update
704 >   returning should be significantly more efficient than executing a refresh query.
705 >
706 >   This behaviour change is intended to be backwards compatible and there should be no need to change
707 >   existing programs, other than to improve performance by using the new capability.
708 >
709 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
710 >   they are called when the dataset row is being deleted, there is no value in
711 >   updating the current record from the query result. Instead, a new event handler
712 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
713 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
714 >   by the query. The event handler can then interrogate the query results and
715 >   perform whatever action is necessary. For example to confirm, to the user,
716 >   the deletion of a row with the returned values.
717 >
718 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
719 >   any Computed By or Identity Columns. The IBTables example has been updated to
720 >   illustrate the computation of the employee Full Name on update.
721 >
722 > 5. TIBTable: The GeneratorField property is now published.
723 >
724 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
725     When InsertSQL is generated, the Identity columns are not included in the list of values to
726     be inserted. A RETURNING clause is added to the insert statement to return the value of
727     each Identity column after the insert is executed.
728  
729 + 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
730 +   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
731 +   Insert..Returning clause.
732 +
733 + 8. TIBGenerator: small performance improvement by not preparing query each time
734 +   a new value is generated.
735 +
736 + 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
737 +
738 + 10. Property editors will now sync table name to a System Table when "Include System
739 +    Tables" is selected and the query is for a System Table.
740 +
741 + 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
742 +    values are no longer converted to milliseconds from TDateTime and then back again
743 +    to TDateTime (the conversion to milliseconds is the default TDataset approach).
744 +
745 + 12. Property Editors handling of Stored Procedures.
746 +    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
747 +      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
748 +      query).
749 +    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
750 +
751 + 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
752 +    can be used to select a package. If non-empty, the stored procedure name is
753 +    expected to be a stored procedure defined in the specified package and the
754 +    generated SQL will be as required for a stored procedure located in a package.
755 +
756 + 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
757 +    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
758 +    which a stored procedure can be selected. With no package name selected, non-package
759 +    stored procedures are listed.
760 +
761 + 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
762 +    for password on reconnect.
763 +
764 + 16. TIBDatabase: use IAttachment for connection default character set id, code page
765 +    and character set name.
766 +
767 + 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
768 +    DB info lookups"
769 +
770 + 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
771 +
772 + 19. Add a property Editor for TIBUpdate.RefreshSQL.
773 +
774 + 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
775 +    parameters. This stops an exception being raised when the field cannot be
776 +    located in the record buffer.
777 +
778 + 21. Property Editors now automatically include System Tables when opened and when the query table
779 +    is a System Table.
780 +
781 + 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
782 +    This avoids errors due to a stale SQRB or SRB being used for the next query.
783 +
784 + 23. IBServices: Service attach parameters now include "expected_db". This is used to
785 +    add the SPB item isc_spb_expected_db. This names a database using
786 +    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
787 +    database. examples/services re-written to illustrate use of "expected_db".
788 +
789 + 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
790 +    This avoids truncated backups when the server returns a timeout (busy) response.
791 +
792 + 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
793 +
794 + 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
795 +    databasenames. These are respectively expanded to the local system's temp directory
796 +    (including trailing delimiter) or to a prescribed data directory (including
797 +    trailing delimiter). Under Unix systems the data directory is a hidden directory
798 +    in the user's home directory. The hidden directory name is either the string returned
799 +    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
800 +    Under Windows, the directory is the same as the Data Directory as decribed
801 +    above but instead prefixed by the User's application data path. These may be
802 +    used to improve application portability for Personal Databases.
803 +
804 + 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
805 +    this has not worked for a long time and is not useful either. FieldDefs should be
806 +    managed using the Fields Editor as with any other dataset. To access the fields
807 +    editor for a TIBTable component, double click on the component. The fields editor
808 +    is then displayed.
809 +
810 + 28. TIBDatabaseInfo: new properties/function
811 +     * DateDBCreated (returns date/time database created)
812 +     * TransactionCount (returns no. of active transactions)
813 +     * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
814 +     * PagesFree (Firebird 3 or later)
815 +     * PagesUsed (Firebird 3 or later)
816 +     * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
817 +     * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
818 +
819 + 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
820 +
821 + 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
822 +
823 + 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
824 +    the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
825 +
826 + 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
827 +    in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
828 +    firing during backup and restore.
829 +
