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

419 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
420 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
421 >
422 > 5. New published property for TIBCSVDataOut:
423 >     property QuoteStrings: boolean (default true)
424 >
425 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
426 >   used to delimit each and every string in the output.
427 >
428 > 6. New published properties for TIBCSVDataOut:
429 >    property FieldSeparator: string;
430 >    property HeaderSeparator: string;
431 >
432 >   Respectively, these provide the separator character(s) used to separate fields
433 >   in data and header rows. Both default to ','.
434 >
435 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
436 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
437 >    property OnFormatTextString;
438 >
439 >   This event handler can be used to process text strings before they are included
440 >   in the output e.g. to replace unprintable characters with alternative strings.
441 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
442 >
443 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
444 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
445 >   and without raising and exception if it does not.
446 >
447 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
448 >   consistency with SQL queries.
449 >
450 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
451 >    When true, SQL statement parameter names are parsed case sensitive. Note for
452 >    TIBDataSet only applies to Select query.
453 >
454 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
455 >    an IDE exception.
456 >
457 > 12. LocalDBSupport: initial database creation should now work correctly
458 >    when the schema source is an sql file.
459 >
460 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
461 >    when defined, this handler will be called by the internal TIBXScript during
462 >    initial database creation when the schema source is an sql file and may be used
463 >    to provide a visual indication of progress in console mode.
464 >
465 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
466 >    to true while a new local database is being created and its schema populated.
467 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
468 >    when the database is disconnected/connected during the create DB procedure.
469 >
470 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
471 >    are now always ignored and replaced by the user name and password provided as
472 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
473 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
474 >    completely ignored if this property is true.
475 >
476 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
477 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
478 >    ImageIndex and SelectImageIndex values on AddNode.
479 >
480 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
481 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
482 >    the same database connection.
483 >
484 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
485 >    if provided, this should be an conditional SQL expression suitable for
486 >    including in an SQL Select statement "where" clause. If non-empty and the
487 >    "Filtered" property is true then the SQL expression provided as the value of
488 >    the "Filter" property is "ANDed" with any existing condition statement
489 >    in the SQL statement's "Where" clause.
490 >
491 >    If the "Filter" property is set at run time, the "Filtered" property is true
492 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
493 >
494 >    The "Filter" condition may include IBX style parameters. In which case, their
495 >    value must be set by the dataset's "OnBeforeOpen" event handler.
496 >
497 >    This is a public property for TIBDataSet and TIBQuery query and intended for
498 >    use at run time.
499 >
500 >    Note: The property is a published property of TIBTable. The TIBTable functionality
501 >    is unaffected by this change.

503 > IBX Change Log  version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
504 >
505 > 1. Remove need to check for IsMultiThread by providing access to GUI timers via
506 >   IBGUIInterface. Note: master/detail delay timer does not apply to console
507 >   mode apps.
508 >
509 > 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
510 >   statement. This avoids problems if "Execute Block" is used as the Query.
511 >
512 > 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
513 >   internal SQL tokeniser routines.
514 >
515 > 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
516 >   as a select statement, with or without CTEs.
517 >
518 > 5. IBSQLParser: parser now recognises the "ROWS" clause.
519 >
520 > 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
521 >   internal SQL tokeniser routines.
522 >
523 > 7.  Fix error in TIBXScript processing of "set" statements. This avoids exceptions
524 >    being raised for valid set statements processed by a data formatter.
525 >
526 > 8. New published property for TIBDatabase and TIBXServicesConnection. This is
527 >   FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
528 >   the path of the Firebird Library used by the database/services connection.
529 >
530 > 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
531 >   is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
532 >   services connection.
533 >
534 > 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
535 >   or param name is not a valid SQL identifier.
536 >
537 > 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
538 >    view of whether the text box should be editable when no DataSource is specified.
539 >    TIBLookupComboEditBox has been updated to workaround this problem. As long as
540 >    ReadOnly is false, the text box is editable when no DataSource is specified.
541 >
542 > 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
543 >    the FBLIB environment variable. If you do not want to permit this then you
544 >    must modify the Register procedure in the design/IBDBReg.pas unit to remove
545 >    this setting.

553 >
554 > IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
555 > all previous copies of the IBX source code tree before installing this release.
556 >
557 > The IBX packages used by most users have not changed, with one exception. The
558 > IBServices unit has been moved to the package iblegacyServices.lpk. To continue
559 > to use the IBServices unit in your applications, please add the iblegacyServices
560 > to the list of dependencies. To do this, open the Project Inspector and select
561 > Add->New Requirement and select "ibLegacyServices" from the list of available
562 > packages.
563 >
564 > 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
565 >   the IBServices unit providing what is intended to be a clearer and easier to
566 >   use set of IB Services components. See Chapter 10 of the IBX User Guide for
567 >   more information and the guide to "Firebird Service Management Using IBX".
568 >   As indicated above, the legacy services components are still available and
569 >   provided in a separate package. There is no need to update working applications
570 >   using the older versions except for an additional package dependency.
571 >
572 > 2. The IBX packages and source code tree have been re-organised in an attempt to
573 >   finally get rid of the "duplicate ppu" warnings. This re-organisation should
574 >   not affect existing users. Section 2.3 of the IBX User Guide describes the
575 >   new set of IBX packages.
576 >
577 > 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
578 >   updated to use the new Services API components.
579 >
580 > 4. The iblocal package has been updated to use the new Services API components.
581 >
582 > 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
583 >   TIBXSecurityService. It had been wrongly classified in the previous version
584 >   as a per database configuration item. It is global to a server and hence
585 >   correctly positioned as part of the Security Package. In the DBAdmin example,
586 >   the setting has moved to the mappings page.
587 >
588 > 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
589 >   are ignored.
590 >
591 > 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
592 >   closed before the database is dropped. Before and After Disconnect event handlers
593 >   are also fired.
594 >
595 > 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
596 >   is started and not just the first time.
597 >
598 > 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
599 >   depenendency with comp type.
600 >
601 > 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
602 >
603 > 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
604 >    then this is recognised and not ignored.
605 >
606 > 12. TIBDataSet, TIBQuery, TIBTable: additions:
607 >    function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
608 >    function GetPerfStatistics(var stats: TPerfCounters): boolean;
609 >    property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
610 >
611 >    GetRowsAffected returns the affected row counts from the last insert/update/delete
612 >    if EnableStatistics = true then GetPerfStatistics returns the current stats
613 >    counters for the select query. Note: stats accumulate after each fetch from
614 >    the database. To get total query cost after open, call the "Last" method
615 >    and then GetPerfStatistics.
616 >
617 >    See ibx/examples/consolemode for an example of the use of GetPerfStatistics
618 >
619 > 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
620 >    in parenthesises.
621 >
622 > 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
623 >    SQL identifiers are always delimited by double quotes. If false, then they are
624 >    only delimited if the identifier is a reserved word, contains lower case or special
625 >    characters. Set this property to true to retain previous behaviour.
626 >
627 > 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
628 >    are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
629 >
630 > 16. TIBDataSet, TIBQuery, TIBTable: addition:
631 >       property MasterDetailDelay: integer {defaults to zero}
632 >
633 >    When non-zero and the dataset is a detail table referencing a master table
634 >    through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
635 >    then a synchronisation delay is added (in milliseconds) between the master
636 >    row changing and the detail dataset being re-opened. If the master dataset
637 >    is scrolled before the delay expires then the delay is reset. This can be used
638 >    to avoid performance overheads when scrolling through a large master dataset.
639 >
640 >    Note: uses fptimer and hence requires a thread manager. Under Linux the
641 >    chreads unit must be included in your project. TTimer is not used in order
642 >    to avoid an LCL dependency. Requires FPC 3.0.2 or later.
643 >
644 > 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
645 >    with Extract Option eoDatabase.
646 >
647 > 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
648 >    When a deLayoutChanged event is reported on the ListSource dataset, the
649 >    combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
650 >    relationship with the control's datasource (master).
651 >
652 > 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
653 >
654 > 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
655 >    stubs. Pedantic fix really, as procedures output in dependency order anyway.
656 >
657 > 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
658 >    DDL (Firebird 3 and later only).
659 >
660 > 22. TIBLookupComboBox Autocomplete Fixes:
661 >    i. Only appended text is now selected after autocomplete.
662 >    ii. Uppercase keys no longer ignored for autocomplete.
663 >    iii. Retain Prefix case is now honoured correctly.
664 >    iv. When a DataSource is assigned, typing after autocomplete now extends prefix
665 >        before autocomplete performed. i.e. behaviour now the same as when
666 >        no DataSource assigned.
667 >
668 > 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
669 >    between SQL statements.
670 >
671 > 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
672 >    ObjectNames are converted to upper case before matching against metadata object
673 >    names, unless the objectname is delimited by double quotes, in which case, the
674 >    double quotes are removed and the remaining string is used (unmodified) to match
675 >    against the metadata object name.
676 >
677 >    If true then the ObjectName is used as is without modification and matched
678 >    against the metadata object name. No attempt is made to remove double quotes.
679 >
680 > 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
681 >    with eoTrigger, these extract types can be used to select only Database Triggers,
682 >    or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
683 >
684 > 26. TIBXScript: If an exception occurs during the processing of a statement, the
685 >    statement separate character is now reset to the default (';').
686 >
687 > 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
688 >
689 > 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
690 >    a commit or reconnect statement and instead activated only when next SQL statement
691 >    is executed.
692 >
693 > 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
694 >
695 > 30. TIBXScript: case insensitive regex now used when matching statements instead of
696 >    converting statement to upper case.
697 >
698 > 31. TIBExtract: metadata comments now supported. New published property
699 >    IncludeMetaDataComments (default true). If true then metadata comments included
700 >    in extracted DDL. New Extract Object member eoComments. This may be used with
701 >    ExtractObject method to list all metadata comments.
702 >
703 > 32. TIBExtract: ListObjectNames method added.
704 >
705 > 33. Updated Database component editor to support additional connection string
706 >    types.
707 >
708 > IBX Change Log  version  (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
709 >
710 > NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
711 > AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
712 > RELEASE.
713 >
714 > NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
715 >
716 > 1. IBExtract: Identity columns - add additional check for null column for generator name.
717 >
718 > 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
719 >   The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
720 >   information). However, this is also a very useful mechanism for returning updated computed by
721 >   column values. Values returned as a result of executing an Insert or Update statement
722 >   replace existing values in the current row for each corresponding column.
723 >
724 >   Previously, if a dataset's select query included read only (computed by) fields then
725 >   an automatic row refresh was performed after an insert or update query had been processed,
726 >   irrespective of the setting of the "ForcedUpdates" property. This has changed such
727 >   that an automatic refresh is no longer performed if an insert or update query contains
728 >   a returning clause that updates one or more fields on the current row. A full row
729 >   refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
730 >   field values and the select query contains read only fields. Use of Insert/update
731 >   returning should be significantly more efficient than executing a refresh query.
732 >
733 >   This behaviour change is intended to be backwards compatible and there should be no need to change
734 >   existing programs, other than to improve performance by using the new capability.
735 >
736 > 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
737 >   they are called when the dataset row is being deleted, there is no value in
738 >   updating the current record from the query result. Instead, a new event handler
739 >   "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
740 >   an OnDeleteReturning event handler is provided then it is called with the IResults returned
741 >   by the query. The event handler can then interrogate the query results and
742 >   perform whatever action is necessary. For example to confirm, to the user,
743 >   the deletion of a row with the returned values.
744 >
745 > 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
746 >   any Computed By or Identity Columns. The IBTables example has been updated to
747 >   illustrate the computation of the employee Full Name on update.
748 >
749 > 5. TIBTable: The GeneratorField property is now published.
750 >
751 > 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
752 >   When InsertSQL is generated, the Identity columns are not included in the list of values to
753 >   be inserted. A RETURNING clause is added to the insert statement to return the value of
754 >   each Identity column after the insert is executed.
755 >
756 > 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
757 >   Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
758 >   Insert..Returning clause.
759 >
760 > 8. TIBGenerator: small performance improvement by not preparing query each time
761 >   a new value is generated.
762 >
763 > 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
764 >
765 > 10. Property editors will now sync table name to a System Table when "Include System
766 >    Tables" is selected and the query is for a System Table.
767 >
768 > 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
769 >    values are no longer converted to milliseconds from TDateTime and then back again
770 >    to TDateTime (the conversion to milliseconds is the default TDataset approach).
771 >
772 > 12. Property Editors handling of Stored Procedures.
773 >    * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
774 >      which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
775 >      query).
776 >    * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
777 >
778 > 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
779 >    can be used to select a package. If non-empty, the stored procedure name is
780 >    expected to be a stored procedure defined in the specified package and the
781 >    generated SQL will be as required for a stored procedure located in a package.
782 >
783 > 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
784 >    a "Package Name" drop down box to allow selection of a Firebird 3 Package from
785 >    which a stored procedure can be selected. With no package name selected, non-package
786 >    stored procedures are listed.
787 >
788 > 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
789 >    for password on reconnect.
790 >
791 > 16. TIBDatabase: use IAttachment for connection default character set id, code page
792 >    and character set name.
793 >
794 > 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
795 >    DB info lookups"
796 >
797 > 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
798 >
799 > 19. Add a property Editor for TIBUpdate.RefreshSQL.
800 >
801 > 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
802 >    parameters. This stops an exception being raised when the field cannot be
803 >    located in the record buffer.
804 >
805 > 21. Property Editors now automatically include System Tables when opened and when the query table
806 >    is a System Table.
807 >
808 > 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
809 >    This avoids errors due to a stale SQRB or SRB being used for the next query.
810 >
811 > 23. IBServices: Service attach parameters now include "expected_db". This is used to
812 >    add the SPB item isc_spb_expected_db. This names a database using
813 >    an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
814 >    database. examples/services re-written to illustrate use of "expected_db".
815 >
816 > 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
817 >    This avoids truncated backups when the server returns a timeout (busy) response.
818 >
819 > 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
820 >
821 > 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
822 >    databasenames. These are respectively expanded to the local system's temp directory
823 >    (including trailing delimiter) or to a prescribed data directory (including
824 >    trailing delimiter). Under Unix systems the data directory is a hidden directory
825 >    in the user's home directory. The hidden directory name is either the string returned
826 >    from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
827 >    Under Windows, the directory is the same as the Data Directory as decribed
828 >    above but instead prefixed by the User's application data path. These may be
829 >    used to improve application portability for Personal Databases.
830 >
831 > 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
832 >    this has not worked for a long time and is not useful either. FieldDefs should be
833 >    managed using the Fields Editor as with any other dataset. To access the fields
834 >    editor for a TIBTable component, double click on the component. The fields editor
835 >    is then displayed.
836 >
837 > 28. TIBDatabaseInfo: new properties/function
838 >     * DateDBCreated (returns date/time database created)
839 >     * TransactionCount (returns no. of active transactions)

905   1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
906     changes.
# Line 24 | Line 926 | IBX Change Log  version
926     screen centre. Previously some were "poDesigned" which may be inappropriate
927     for multi monitor desktops.
928  
929 + 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
930 +
931 + 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
932 +    a transaction and always reset the object.
933 +
934 + 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
935 +
936 + 13. TIBXScript: Allow for override of database filename in Create Database statements.
937 +
938 + 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
939 +    to a gbak format archive.
940 +
941 + 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
942 +
943 + 16. IBLocaldb: Drop database if error creating an empty database.
944 +
945 + 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
946 +    unless selected node not in current dataset.
947 +
948 + 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
949 +    to TIBCustomService, and IBlocalDB code tidy up.
950 +
951 + 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
952 +    behaviour due to uninitialised variable.
953 +
954 + 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
955 +    integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
956 +
957 + 21. IBSQL: When Database changed ensure that all resources are freed.
958 +
959 + 22. IBCustomDataset: When database changed ensure that queries an unprepared.
960 +
961 + 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
962 +    * Line Wrap on SQL Token boundaries (on user command)
963 +    * auto-complete table names in drop down list of table names
964 +    * Double click on tablename or field name adds to SQL text
965 +
966 + 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
967 +
968 + 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
969 +    TVariantArray. Seems to avoid memory corruption in Windows (probably a
970 +    workaround for a problem in fpc 3.0.4 win64).
971 +
972 + 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
973 +
974 + 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
975 +

977  
978   1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
# Line 44 | Line 993 | IBX Change Log  version
993     that BindFields is called when the query is next activated. Avoids FieldName
994     not found error.
995  
996 + 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
997 +   purpose and allows the programmer to define any action they want for Update, Insert
998 +   or Delete. This may be complex SQL (similar to a Trigger), application specific
999 +   filtering of updates, or use of statements such as Grant or Revoke instead of
1000 +   normal DML. See User Manual for more information.
1001 +
