1 + IBX Change Log  version (2.6-4 Build 14172) Thu, 04 Jan 2024 11:55:41 +0000
2 +
3 + 1. TIBCustomDataSet.ApplyUpdates: ensure controls are not permanently disabled
4 +   if ApplyUpdates called before a cursor exists.
5 +
6 + 2. TIBCustomDataSet.CreateBlobStream: add check for empty dataset before
7 +   creating the blob.
8 +
9 + 3. TIBCustomDataset.Requery: The display buffer pool is now also reset avoiding
10 +   issues with left over pointers to invalid internal buffers.
11 +
12 + 4. TIBCustomDataset.PrimaryKeys when used in InternalRefresh. when more than one
13 +   primary key is used by the dataset then the list of primary keys is now
14 +   properly separated by a ';'.
15 +
16 + 5. When refresh is called for a dataset without any primary keys (e.g. views and
17 +   stored procedures), the internal record number is now used to restore the cursor
18 +   following the refresh. However, it should be noted that cannot be 100% reliable.
19 +   The internal record number simply reflects the record fetch order and this can
20 +   change between successive queries if records are inserted or deleted by the
21 +   current or another user (if the read_committed transaction isolation level is used).
22 +
23 + 6. Inserting a record at the start of a grid and then resizing the grid should
24 +   no longer result in an apparent duplication of records in the grid. Note: this
25 +   was due to TDataset.SetCurrentRecord ignoring the bookmark flag (bfInserted). IBX
26 +   works around this by no longer using this bookmark flag value.
27 +
28 + 7. Inserting a record into an empty grid and then resizing the grid should
29 +   no longer result in an apparent duplication of records in the grid.
30 +
31 + IBX Change Log  version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100
32 +
33 + 1. Update to calls to EInterbaseError to add default code page. Consequential
34 +   on change to fbintf.
35 +
36 + 2. Update some examples to replace test for null date with the NullDate constant
37 +   instead of zero. This is because Laz 3.0 changes the value of NullDate.
38 +
39 + IBX Change Log  version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100
40 +
41 + 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
42 +   with later versions of fpc - later than 3.2.2.
43 +
44 + 2. IBUpdateSQL. update internal queries if parent dataset database changed.
45 +
46 + 3. IBUpdateSQL: Do not prepare an empty internal query.
47 +
48 + 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
49 +
50 + 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
51 +
52 + IBX Change Log  version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
53 +
54 + 1. Maintenance update of 2.6.0. This version is still at beta.
55 +
56 + 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
57 +   See https://gitlab.com/freepascal.org/lazarus/lazarus/-/commit/53aaae9c5e2a5edac5b1d2f70739a8ef7b0a9623
58 +
59 + 3. ibxscript: When parsing a store procedure or function with a variable name
60 +   enclosed in doublequotes, the double quotes are no longer removed.
61 +
62 + IBX Change Log  version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
63 +
64 + NOTE: THIS VERSION RE-WRITES THE INTERNAL BUFFER MANAGER AND SHOULD BE CONSIDERED
65 +      AS BETA SOFTWARE. EVEN THOUGH IT HAS PASSED ALL REGRESSION TESTS, IT CANNOT
66 +      BE ASSUMED TO BE PRODUCTION READY UNTIL WIDER USE. PLEASE REPORT ANY
67 +      ISSUES TO support@mwasoftware.co.uk
68 +
69 + 1. Complete rewrite of internal buffer management in order to improve performance
70 +   and maintainability. Highlights:
71 +
72 +   * Extending the size of the buffer pool no longer has to copy the entire record
73 +     cache. Instead, a new extent is simply added to the buffer pool.
74 +   * A memory to memory copy of each display buffer now is avoided when scolling the
75 +     dataset.
76 +   * A separate set of buffers is now used for calculated fields. This avoids
77 +     having to keep copies of calculated field values in the buffer cache.
78 +   * Compact bitmaps are used to record null status and need to refresh in each
79 +     buffer.
80 +   * Display buffer type changed from PChar to TRecordBuffer in line with change of
81 +     buffer type in FCL-DB.
82 +
83 + 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
84 +   to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
85 +
86 + 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
87 +   If either or both of these flags are set at design time (using the fields editor)
88 +   then this forces a row refresh on respectively insert or update, or both, when the
89 +   corresponding field is not present in an SQL RETURNING clause.
90 +
91 + 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
92 +   maintainability and readability and to add identification of primary key fields.
93 +
94 + 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
95 +   as a refresh of the current row. However, this is different behaviour to that described
96 +   in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
97 +   the dataset from the underlying database, and attempts to reposition the cursor on
98 +   the same record as it was". IBX now complies with the FPC definition of Refresh.
99 +
100 + 6. A progammatic Row Refresh should no longer be required.
101 +   Use Insert/Update... returning to refresh any fields that may change following an
102 +   insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
103 +   on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
104 +   for the field at Design Time to force a row refresh if not in the returning clause.
105 +
106 + 7. It should now be possible to insert a row into an empty unidirectional dataset.
107 +
108 + 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
109 +   This gives the number of buffers in the initial block for the buffer pool in
110 +   bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
111 +   in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
112 +   for small datasets.
113 +
114 + IBX Change Log  version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
115 +
116 + 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
117 +
118 + 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
119 +
120 + 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
121 +
122 + IBX Change Log  version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
123 +
124 + 1. TIBTransaction: new properties
125 +    property TransactionID: integer read GetTransactionID;
126 +    property IsReadOnly: boolean read GetIsReadOnly;
127 +    {published}
128 +    property TransactionName: string read FTransactionName write SetTransactionName;
129 +
130 + 2. IBCustomDataset: per row blob and array buffer cached clear before processing
131 +   Insert or Update...Returning. This allows blobs and arrays to be returned
132 +   by the statement.
133 +
134 + 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
135 +
136 + 4. TransactionName initialised to a newly generated GUID if empty.
137 +
138 + 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
139 +   for the fbintf package's journaling capability. TIBJournal is used to set the
140 +   file path and filename for the journal file and to Enabled (start journaling) and
141 +   disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
142 +   more information, and comments in IBJournal.pas.
143 +
144 + 6. TIBDatabase.InternalTransaction is now a read only transaction.
145 +
146 + 7. Bug fix: blob id no longer set to null on update when blob has not been
147 +   retrieved.
148 +
149 + 8. Row auto refreshed on update/insert if blob or array field updated and field
150 +   not in a returning clause.
151 +
152 + 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
153 +   buffer overhead and avoids problem when refresh query has a different column
154 +   count to select query i.e. incorrectly changing number of columns.
155 +
156 + 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
157 +
158 + 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
159 +    string. Note that the Version property returns an InterBase compatible version string.
160 +
161 + 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
162 +
163 + IBX Change Log  version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
164 +
165 + 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
166 +   This is for compatibility with Firebird 5 where Update...Returning can return
167 +   a cursor.
168 +
169 + IBX Change Log  version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
170 +
171 + 1. Add try-..except check when initially loading library in IDE. This should
172 + ensure that IDE continues to load even when a failure occurs in IBX load
173 + library.
174 +
175 + 2. IBXScript: now recognises a CASE...END block within a stored procedure and
176 +   hence will correctly detect end of the outer containing block when the block
177 +   contains a SELECT ... CASE ... END construct.
178 +
179 + 3. IBExtract: some further tidying up to remove extraneous white space.
180 +
181 + 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
182 +   errors when extra elements are added to DB.TFieldType.
183 +
184 + 5. IBUpdate: updated to reflect changes to ISQLParam.
185 +
186 + 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
187 +
188 + 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
189 +
190 + 8. IBSQL: Support for scrollable cursors added (note: local databases only)
191 +
192 + IBX Change Log  version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
193 +
194 + 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
195 +   exception of those defined to be one byte wide e.g. DBImplementationNo.
196 +
197 + 2. TIBSQL: Batch Update/Insert support added.
198 +
199 + 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
200 +   is no longer automatically converted to upper case when it is syntactically a
201 +   SQL Identifier. This is to support the use of stored procedures defined e.g.
202 +   as CREATE PROCEDURE "iCASE".
203 +
204 +   There could be a backwards compatibility issue when the StoredProcName was entered
205 +   manually at design time. That is not selected from the drop down list. If the
206 +   StoredProcName is entered in mixed case and the procedure was declared e.g. as
207 +   CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
208 +   ensure that the value of the StoredProcName is all upper case, unless it was
209 +   declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
210 +   quotes).
211 +
212 +   Note that when a stored procedure name was declared delimited in double quotes,
213 +   as in the first example above, the value of the StoredProcName property must not
214 +   include the delimiters (double quotes).
215 +
216 + 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
217 +   upgrade.conf was not found. This replaces silently ignoring the problem.
218 +
219 + 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
220 +   'Version.%.3d' and is used to generate the section header names (for a given
221 +   version no.) in the upgrade.conf file.
222 +
223 + IBX Change Log  version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
224 +
225 + 1. -c command line option added to fbsql example program. Used to set connection
226 +   character set.
227 +
228 + IBX Change Log  version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
229 +
230 + 1. Firebird 4 support added.
231 +
232 + 2. New FB4 data types TIME WITH TIME ZONE, TIMESTAMP WITH TIME ZONE, DECFLOAT and
233 +   extended precision NUMERIC fields are supported.
234 +
235 + 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
236 +
237 + 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
238 +   and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
239 +
240 + 5. IBExtract now supports FB4 enhancements:
241 +   - new data types as above
242 +   - Identity column extensions
243 +   - Default user role
244 +   - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
245 +   - Internal Functions
246 +
247 + 6. IBExtract: new event: OnExtractLines.
248 +
249 + 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
250 +
251 + 8. IBXServices: Server version no. parsing now allows any letter before major version number
252 +   and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
253 +
254 + 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
255 +   format for rendering a time zone.
256 +
257 + 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
258 +     to convert TIME WITH TIME ZONE data type values to and from GMT.
259 +
260 + 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
261 +    IIBGUIInterface and IIBTimerInf respectively.
262 +
263 + 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
264 +    now accessible as properties of TIBDatabase and TIBTransaction respectively.
265 +
266 + 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
267 +    truncated to its fixed character width rather than being right padded with
268 +    white space to the maximum data size.
269 +
270 + 14. TIBTable.Empty table. In additional to deleting all records in the underlying
271 +    table, the internal buffers are now also flushed ensuring that the TIBTable is
272 +    also empty.
273 +
274 + 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
275 +
276 + 16. TIBXControlService descendents: DatabaseName may now be set using a database
277 +    connect string. The database name is extracted from the connect string.
278 +
279 + 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
280 +
281 + 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
282 +
283 + 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
284 +    not being present as required.
285 +
286 + 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
287 +    version that can be customised to work with other database drivers.
288 +
289 + 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
290 +    unnecessary CR at end of line on Unix platforms.
291 +
292 + 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
293 +    seconds in order to reduce risk of message loss.
294 +
295 + 23. ISQLMonitor: read and write count statistics now available via:
296 +      property TIBSQLMonitor.ReadCount;
297 +      IIBSQLMonitorHook.GetWriteCount: integer;
298 +
299 + 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
300 +
301 + IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
302 +
303 + 1.  TIBStringField: when a string value is read from a dataset buffer, if the
304 +    number of UTF8 characters exceeds the string size then string is truncated
305 +    to the maximum string size. This is  usually a problem with fixed width columns
306 +    right padded with white space.
307 +
308 + 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
309 +    If SQLFiltered is set then when a dataset is opened, each line in the
310 +    SQLFilterParams property is assumed to be a SQL condition clause and
311 +    ANDed into the Where clause of the SQL Select statement provided as a
312 +    dataset property. Each such SQL condition thus acts as an additional filter
313 +    on the dataset.
314 +
315 + 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
316 +    side filters).
317 +
318 + 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
319 +   text matches complete entry.
320 +
321 + 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
322 +   dataset are active (avoids risk of access violation if master is inactive)
323 +
324 + 6. TIBEvents: Registered property can now be set at design time even if database not open
325 +
326 + 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
327 +   This should prevent "spillover" of events between sessions.
328 +
329 + 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
330 +   This should ensure that the internal buffer is set up correctly and avoids
331 +   a duplicate initial row.
332 +
333 + 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
334 +   That is, the DataSize should be the field size * character set width. The
335 +   value returned by DataSize is now the same as the Dataset buffer size reserved
336 +   for the field.
337 +
338 + 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
339 +
340 + 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
341 +    and vice-versa. This may result in an exception being raised (correctly) for
342 +    older programs when using dataset fields added to a form and the database has been
343 +    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
344 +    In such cases, the field needs to be deleted in the IDE fields editor and then
345 +    added back in.
346 +
347 + 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
348 +    false if query contains only white space and not just empty.
349 +
350 + 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
351 +    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
352 +    is cancelled.
353 +
354 + 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
355 +    called on a null field.
356 +
357 + 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
358 +    results in an empty dataTC86                Client side Filtered Dataset    1       X
359 + set.
360 +
361 + 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
362 +    a cached update is applied and an exception is raised.
363 +
364 + 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
365 +
366 + 17. Console Mode Local Database support: backup/restore should now work correctly.
367 +
368 + 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
369 +    possible and an exception raised.
370 +
371 + 19. MinimumVersionNo added to Local Database Support. Database will not open if
372 +    below this version no. and upgrade not possible.
373 +
374 + IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
375 +
376 + 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
377 +    not SQL Identifiers are now supported.
378 +
379 + 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
380 +    passed to the Firebird engine for execution.
381 +
382 + 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
383 +    is made to scroll back.
384 +
385 + 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
386 +
387 + 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
388 +   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
389 +
390 + 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
391 +   validated. If no match is found in the list of field names and the database has
392 +   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
393 +   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
394 +
395 + 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
396 +   with fpc 3.2.
397 +
398 + IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
399 +
400 +
401 + 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
402 +   and is used to override the default settings in the client side "firebird.conf" This
403 +   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
404 +   Each line of the string list should be a setting in the same format as "firebird.conf".
405 +   For example "WireCompression = true" in order to request wire compression on the client side.
406 +
407 +   Note: explicit settings in the client side "firebird.conf" appear to take precedence
408 +   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
409 +   also require a compatible setting in the server side "firebird.conf". For example
410 +   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
411 +   compression to be used.
412 +
413 +   Whether or not WireCompression or WireCrypt are in use can be checked using the information
414 +   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
415 +   ibx/examples/dbinfo for examples of how to display this information.
416 +
417 + 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
418 +   is a "convenience" property. If set the "WireCompression=true" is added to the
419 +   ConfigOverrides. If unchecked then this setting is removed.
420 +
421 + 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
422 +   not "INT64".
423 +
424 + 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
425 +   These are:
426 +    property TimestampFormat: string;
427 +    property DateFormat: string;
428 +    property TimeFormat: string;
429 +
430 +   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
431 +   DATETIME and TIME. The format strings use the standard FPC date/time format
432 +   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
433 +
434 +   If any of the above properties are set to an empty string, then the locale default
435 +   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
436 +   locale default is extended by appending '.zzz' to include milliseconds.
437 +
438 +   TIBCSVDataOut by default sets these properties to the empty string, while the other
439 +   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
440 +
441 + 5. New published property for TIBCSVDataOut:
442 +     property QuoteStrings: boolean (default true)
443 +
444 +   If false then strings are unquoted, otherwise, the QuoteChar property value is
445 +   used to delimit each and every string in the output.
446 +
447 + 6. New published properties for TIBCSVDataOut:
448 +    property FieldSeparator: string;
449 +    property HeaderSeparator: string;
450 +
451 +   Respectively, these provide the separator character(s) used to separate fields
452 +   in data and header rows. Both default to ','.
453 +
454 + 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
455 +    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
456 +    property OnFormatTextString;
457 +
458 +   This event handler can be used to process text strings before they are included
459 +   in the output e.g. to replace unprintable characters with alternative strings.
460 +   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
461 +
462 + 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
463 +   Uses "FindParam" if in order to find out if a parameter with a given name exists
464 +   and without raising and exception if it does not.
465 +
466 + 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
467 +   consistency with SQL queries.
468 +
469 + 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
470 +    When true, SQL statement parameter names are parsed case sensitive. Note for
471 +    TIBDataSet only applies to Select query.
472 +
473 + 11. IBEvents: removing a TIBEvent component from a form should no longer result in
474 +    an IDE exception.
475 +
476 + 12. LocalDBSupport: initial database creation should now work correctly
477 +    when the schema source is an sql file.
478 +
479 + 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
480 +    when defined, this handler will be called by the internal TIBXScript during
481 +    initial database creation when the schema source is an sql file and may be used
482 +    to provide a visual indication of progress in console mode.
483 +
484 + 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
485 +    to true while a new local database is being created and its schema populated.
486 +    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
487 +    when the database is disconnected/connected during the create DB procedure.
488 +
489 + 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
490 +    are now always ignored and replaced by the user name and password provided as
491 +    the login parameters for the TIBDatabase referenced from the TIBXScript. The
492 +    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
493 +    completely ignored if this property is true.
494 +
495 + 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
496 +    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
497 +    ImageIndex and SelectImageIndex values on AddNode.
498 +
499 + 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
500 +    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
501 +    the same database connection.
502 +
503 + 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
504 +    if provided, this should be an conditional SQL expression suitable for
505 +    including in an SQL Select statement "where" clause. If non-empty and the
506 +    "Filtered" property is true then the SQL expression provided as the value of
507 +    the "Filter" property is "ANDed" with any existing condition statement
508 +    in the SQL statement's "Where" clause.
509 +
510 +    If the "Filter" property is set at run time, the "Filtered" property is true
511 +    and the dataset is already open, then the dataset is closed and re-opened automatically.
512 +
513 +    The "Filter" condition may include IBX style parameters. In which case, their
514 +    value must be set by the dataset's "OnBeforeOpen" event handler.
515 +
516 +    This is a public property for TIBDataSet and TIBQuery query and intended for
517 +    use at run time.
518 +
519 +    Note: The property is a published property of TIBTable. The TIBTable functionality
520 +    is unaffected by this change.
521 +
522 + IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
523 +
524 + 1. Remove need to check for IsMultiThread by providing access to GUI timers via
525 +   IBGUIInterface. Note: master/detail delay timer does not apply to console
526 +   mode apps.
527 +
528 + 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
529 +   statement. This avoids problems if "Execute Block" is used as the Query.
530 +
531 + 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
532 +   internal SQL tokeniser routines.
533 +
534 + 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
535 +   as a select statement, with or without CTEs.
536 +
537 + 5. IBSQLParser: parser now recognises the "ROWS" clause.
538 +
539 + 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
540 +   internal SQL tokeniser routines.
541 +
542 + 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
543 +    being raised for valid set statements processed by a data formatter.
544 +
545 + 8. New published property for TIBDatabase and TIBXServicesConnection. This is
546 +   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
547 +   the path of the Firebird Library used by the database/services connection.
548 +
549 + 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
550 +   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
551 +   services connection.
552 +
553 + 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
554 +   or param name is not a valid SQL identifier.
555 +
556 + 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
557 +    view of whether the text box should be editable when no DataSource is specified.
558 +    TIBLookupComboEditBox has been updated to workaround this problem. As long as
559 +    ReadOnly is false, the text box is editable when no DataSource is specified.
560 +
561 + 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
562 +    the FBLIB environment variable. If you do not want to permit this then you
563 +    must modify the Register procedure in the design/IBDBReg.pas unit to remove
564 +    this setting.
