1 IBX Change Log version (2.6-4 Build 14188) Mon, 08 Jan 2024 15:20:50 +0000
3 1. TIBCustomDataSet.ApplyUpdates: ensure controls are not permanently disabled
4 if ApplyUpdates called before a cursor exists.
6 2. TIBCustomDataSet.CreateBlobStream: add check for empty dataset before
7 creating the blob.
9 3. TIBCustomDataset.Requery: The display buffer pool is now also reset avoiding
10 issues with left over pointers to invalid internal buffers.
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 ';'.
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).
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.
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.
31 8. IBBufferedCursor. FCurrentRecordStatus now set correctly when selecting a
32 specific record number.
34 9. IBCustomDataset: Calls to AfterScroll during a Locate operation are now suppressed
35 until the end of the locate operation.
37 10.IBCustomDataset: Calls to BeforeScroll during a Locate operation are now suppressed.
38 BeforeScroll is called once before the locate operation.
40 IBX Change Log version (2.6-3 Build 14080) Sat, 21 Oct 2023 14:14:22 +0100
42 1. Update to calls to EInterbaseError to add default code page. Consequential
43 on change to fbintf.
45 2. Update some examples to replace test for null date with the NullDate constant
46 instead of zero. This is because Laz 3.0 changes the value of NullDate.
48 IBX Change Log version (2.6-2 Build 14016) Sat, 05 Aug 2023 11:54:55 +0100
50 1. Fixed repeated "type" keyword in IBBufferCursors. This may cause a compile error
51 with later versions of fpc - later than 3.2.2.
53 2. IBUpdateSQL. update internal queries if parent dataset database changed.
55 3. IBUpdateSQL: Do not prepare an empty internal query.
57 4. IBBufferedCursors: avoid range error when max field no. is > fields.count
59 5. IBBufferedCursors: avoid End of File error if refresh query returns and empty row count
61 IBX Change Log version (2.6-1 Build 13985) Mon, 17 Jul 2023 14:16:41 +0100
63 1. Maintenance update of 2.6.0. This version is still at beta.
65 2. Reverse out changes to DrawCellText signature in IBArrayGrid and IBDynamic Grid.
66 See
68 3. ibxscript: When parsing a store procedure or function with a variable name
69 enclosed in doublequotes, the double quotes are no longer removed.
71 IBX Change Log version (2.6-0 Build 13976) Thu, 22 Jun 2023 13:49:22 +0100
78 1. Complete rewrite of internal buffer management in order to improve performance
79 and maintainability. Highlights:
81 * Extending the size of the buffer pool no longer has to copy the entire record
82 cache. Instead, a new extent is simply added to the buffer pool.
83 * A memory to memory copy of each display buffer now is avoided when scolling the
84 dataset.
85 * A separate set of buffers is now used for calculated fields. This avoids
86 having to keep copies of calculated field values in the buffer cache.
87 * Compact bitmaps are used to record null status and need to refresh in each
88 buffer.
89 * Display buffer type changed from PChar to TRecordBuffer in line with change of
90 buffer type in FCL-DB.
92 2. TIBUpdateSQL: changes to SQL text will close linked dataset if open. This is
93 to ensure same behaviour as TIBDataset, TIBTable and TIBStoredProcedure.
95 3. TField Provider Flags: pfRefreshOnInsert and pfRefreshOnUpdate are now supported.
96 If either or both of these flags are set at design time (using the fields editor)
97 then this forces a row refresh on respectively insert or update, or both, when the
98 corresponding field is not present in an SQL RETURNING clause.
100 4. TIBCustomDataset.FieldDefsFromQuery moved to a helper class (TFieldDefsMaker) in order to improve
101 maintainability and readability and to add identification of primary key fields.
103 5. TIBQuery, TIBDataset and TIBTable. Traditionally, IBX has implemented the Refresh method
104 as a refresh of the current row. However, this is different behaviour to that described
105 in the FPC documentation for TDataset.Refresh which is described as "refetches the data in
106 the dataset from the underlying database, and attempts to reposition the cursor on
107 the same record as it was". IBX now complies with the FPC definition of Refresh.
109 6. A progammatic Row Refresh should no longer be required.
110 Use Insert/Update... returning to refresh any fields that may change following an
111 insert or update i.e. Identify fields on Insert only, Computed By, Blob and array fields
112 on both. If there are any other fields (e.g. updated by triggers) set the appropriate ProviderFlag
113 for the field at Design Time to force a row refresh if not in the returning clause.
115 7. It should now be possible to insert a row into an empty unidirectional dataset.
117 8. New TIBQuery, TIBDataSet and TIBTable property: BufferChunksInFirstBlock (default 50).
118 This gives the number of buffers in the initial block for the buffer pool in
119 bi-directional datasets. BufferChunks (default 1000) gives the number of buffers
120 in subsequent buffer pool blocks. This avoids large and mostly unused memory allocations
121 for small datasets.
123 IBX Change Log version (2.5-1 Build 13927) Tue, 6 Dec 2022 23:13:00 +0000
125 1. IBCustomDataset: avoid problem with additions to TFieldType by using a subset instead.
127 2. TIBDynamicGrid: change DrawCellText declaration to comply with laz 2.3.0
129 3. TIBArrayGrid: change DrawCellText declaration to comply with laz 2.3.0
131 IBX Change Log version (2.5-0 Build 13868) Fri, 29 Jul 2022 09:52:01 +0100
133 1. TIBTransaction: new properties
134 property TransactionID: integer read GetTransactionID;
135 property IsReadOnly: boolean read GetIsReadOnly;
136 {published}
137 property TransactionName: string read FTransactionName write SetTransactionName;
139 2. IBCustomDataset: per row blob and array buffer cached clear before processing
140 Insert or Update...Returning. This allows blobs and arrays to be returned
141 by the statement.
143 3. TSQLXMLReader moved from IBXScript to package fbintf unit IBUtils.
145 4. TransactionName initialised to a newly generated GUID if empty.
147 5. New unit: IBJournal. This provides the TIBJournal component which is a wrapper
148 for the fbintf package's journaling capability. TIBJournal is used to set the
149 file path and filename for the journal file and to Enabled (start journaling) and
150 disable (stop journaling). See fbintf/doc/README.ClientSideJournaling.pdf for
151 more information, and comments in IBJournal.pas.
153 6. TIBDatabase.InternalTransaction is now a read only transaction.
155 7. Bug fix: blob id no longer set to null on update when blob has not been
156 retrieved.
158 8. Row auto refreshed on update/insert if blob or array field updated and field
159 not in a returning clause.
161 9. ColumnCount moved from record buffer header to a single per dataset count. Reduces
162 buffer overhead and avoids problem when refresh query has a different column
163 count to select query i.e. incorrectly changing number of columns.
165 10. IBExtract: support added for UDR Functions, Procedure and Trigger declarations.
167 11. TIBDatabaseInfo. New property FirebirdVersion. This returns the current Firebird version
168 string. Note that the Version property returns an InterBase compatible version string.
170 12. IBExtract: ensure sql identifiers returned as a LIST are always quoted.
172 IBX Change Log version (2.5-0 Build 12933) Mon, 29 Nov 2021 14:59:54 +0000
174 1. IBCustomDataset: Modify TISQL component now defaults to GoToFirstRecordOnExecute := true.
175 This is for compatibility with Firebird 5 where Update...Returning can return
176 a cursor.
178 IBX Change Log version (2.4-3 Build 12886) Sat, 23 Oct 2021 14:58:30 +0100
180 1. Add try-..except check when initially loading library in IDE. This should
181 ensure that IDE continues to load even when a failure occurs in IBX load
182 library.
184 2. IBXScript: now recognises a CASE...END block within a stored procedure and
185 hence will correctly detect end of the outer containing block when the block
186 contains a SELECT ... CASE ... END construct.
188 3. IBExtract: some further tidying up to remove extraneous white space.
190 4. IBCustomDataSet: DefaultFieldClasses array declaration updated to avoid compile time
191 errors when extra elements are added to DB.TFieldType.
193 5. IBUpdate: updated to reflect changes to ISQLParam.
195 6. IBXScript: now correctly parses a DECLARE statement which includes a quoted string.
197 7. IBExtract: for ODS >=13, increment generator value by one for ALTER SEQUENCE statement.
199 8. IBSQL: Support for scrollable cursors added (note: local databases only)
201 IBX Change Log version (2.4-2 Build 12773) Mon, 23 Aug 2021 11:59:42 +0100
203 1. TIBDatabaseInfo: review and tidy-up of property types. Most widen to int64 with the
204 exception of those defined to be one byte wide e.g. DBImplementationNo.
206 2. TIBSQL: Batch Update/Insert support added.
208 3. TIBStoredProc: when generating the SQL, the value of the StoredProcName property
209 is no longer automatically converted to upper case when it is syntactically a
210 SQL Identifier. This is to support the use of stored procedures defined e.g.
213 There could be a backwards compatibility issue when the StoredProcName was entered
214 manually at design time. That is not selected from the drop down list. If the
215 StoredProcName is entered in mixed case and the procedure was declared e.g. as
216 CREATE PROCEDURE iCASE, then the SQL generation will be incorrect. You should
217 ensure that the value of the StoredProcName is all upper case, unless it was
218 declared under dialect 3 and explicitly as mixed case (i.e. delimited by double
221 Note that when a stored procedure name was declared delimited in double quotes,
222 as in the first example above, the value of the StoredProcName property must not
223 include the delimiters (double quotes).
225 4. IBXUpgradeConfFile: an exception is now raised if a patch file specified in
226 upgrade.conf was not found. This replaces silently ignoring the problem.
228 5. TIBLocalDBSupport: new property "SectionHeaderTemplate". This defaults to
229 'Version.%.3d' and is used to generate the section header names (for a given
230 version no.) in the upgrade.conf file.
232 IBX Change Log version (2.4-1 Build 12550) Wed, 23 Jun 2021 13:59:14 +0100
234 1. -c command line option added to fbsql example program. Used to set connection
235 character set.
237 IBX Change Log version (2.4-0 Build 12543) Mon, 22 Feb 2021 11:00:08 +0000
239 1. Firebird 4 support added.
242 extended precision NUMERIC fields are supported.
244 3. TFmtBCDField is used to support access to DECFLOAT and extended precision NUMERIC fields.
246 4. TIBDateTimeField and TIBTimeField are introduced in support of TIMESTAMP WITH TIME ZONE
247 and TIME WITH TIME ZONE fields. These inherit from TDateTimeField.
249 5. IBExtract now supports FB4 enhancements:
250 - new data types as above
251 - Identity column extensions
252 - Default user role
253 - SQL Security clause for Database, Tables, Procedures, Functions and Triggers
254 - Internal Functions
256 6. IBExtract: new event: OnExtractLines.
258 7. IBExtract: revert create trigger to legacy syntax see Firebird CORE-6243, CORE-5545 and DOC-145
260 8. IBXServices: Server version no. parsing now allows any letter before major version number
261 and is no longer restricted to 'V' e.g. "LI-T4.0.0.1436 Firebird 4.0 Beta 1"
263 9. TIBDataSet and TIBQuery: new property TZTextOption. Used to determine the default
264 format for rendering a time zone.
266 10. TIBDataSet and TIBQuery: new property DefaultTZDate. Used to provide the default date
267 to convert TIME WITH TIME ZONE data type values to and from GMT.
269 11. Unit name IBTypes changed to IBInternals. Internal interfaces TIBGUIInterface and TIBTimerInf renamed to
270 IIBGUIInterface and IIBTimerInf respectively.
272 12. Constants: DPBPrefix and TPBPrefix moved to IB unit. DPBConstantNames and TPBConstantNames
273 now accessible as properties of TIBDatabase and TIBTransaction respectively.
275 13. String Fields: when a fixed character with (CHAR) field is returned, it is now
276 truncated to its fixed character width rather than being right padded with
277 white space to the maximum data size.
279 14. TIBTable.Empty table. In additional to deleting all records in the underlying
280 table, the internal buffers are now also flushed ensuring that the TIBTable is
281 also empty.
283 15. TBatchSQLStatementReader: Line buffer is now cleared on call to reset.
285 16. TIBXControlService descendents: DatabaseName may now be set using a database
286 connect string. The database name is extracted from the connect string.
288 17. DBControlGrid: Minor bug fixes. avoid AV on form closure, avoid black panel
290 18. TIBExtract: Data type of COMPUTED By columns is no longer included in SQL.
292 19. Local database on Linux and with legacy API and FB 2.5 embedded server: fixed problem with password
293 not being present as required.
295 20. IBTreeView split into DBTreeView and IBTreeView. This former is an IBX indepedent
296 version that can be customised to work with other database drivers.
298 21. ISQLMonitor: use platform specific LineEnding to delimit messages. Avoids
299 unnecessary CR at end of line on Unix platforms.
301 22. ISQLMonitor: Unix: Default semaphore timeout increased from 1 second to 10
302 seconds in order to reduce risk of message loss.
304 23. ISQLMonitor: read and write count statistics now available via:
305 property TIBSQLMonitor.ReadCount;
306 IIBSQLMonitorHook.GetWriteCount: integer;
308 24. ISQLMonitor tidy up and unit split. IPC functions moved to new unit IBIPC.
310 IBX Change Log version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
312 1. TIBStringField: when a string value is read from a dataset buffer, if the
313 number of UTF8 characters exceeds the string size then string is truncated
314 to the maximum string size. This is usually a problem with fixed width columns
315 right padded with white space.
317 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
318 If SQLFiltered is set then when a dataset is opened, each line in the
319 SQLFilterParams property is assumed to be a SQL condition clause and
320 ANDed into the Where clause of the SQL Select statement provided as a
321 dataset property. Each such SQL condition thus acts as an additional filter
322 on the dataset.
324 3. The Filtered property inherited from TDataset is no longer used for SQL (server
325 side filters).
327 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
328 text matches complete entry.
330 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
331 dataset are active (avoids risk of access violation if master is inactive)
333 6. TIBEvents: Registered property can now be set at design time even if database not open
335 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
336 This should prevent "spillover" of events between sessions.
338 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
339 This should ensure that the internal buffer is set up correctly and avoids
340 a duplicate initial row.
342 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
343 That is, the DataSize should be the field size * character set width. The
344 value returned by DataSize is now the same as the Dataset buffer size reserved
345 for the field.
347 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
349 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
350 and vice-versa. This may result in an exception being raised (correctly) for
351 older programs when using dataset fields added to a form and the database has been
352 upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
353 In such cases, the field needs to be deleted in the IDE fields editor and then
354 added back in.
356 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
357 false if query contains only white space and not just empty.
359 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
360 should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
361 is cancelled.
363 13. IBCustomDataset: SetArrayIntf should no longer cause an access violation if
364 called on a null field.
366 14. IBCustomDataSet: An access violation should no longer occur when calling CancelUpdates
367 results in an empty dataTC86 Client side Filtered Dataset 1 X
368 set.
370 15. IBCustomDataSet: OnUpdateError should now be called in all circumstances when
371 a cached update is applied and an exception is raised.
373 16. IBCustomDataSet: Avoid access violation when SetBookmarkData called with nil pointer.
375 17. Console Mode Local Database support: backup/restore should now work correctly.
377 18. Local Database Support: if an upgrade fails, a downgrade is now performed if
378 possible and an exception raised.
380 19. MinimumVersionNo added to Local Database Support. Database will not open if
381 below this version no. and upgrade not possible.
383 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
385 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
386 not SQL Identifiers are now supported.
388 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
389 passed to the Firebird engine for execution.
391 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
392 is made to scroll back.
394 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
396 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
397 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
399 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
400 validated. If no match is found in the list of field names and the database has
401 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
402 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
404 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
405 with fpc 3.2.
407 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
410 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
411 and is used to override the default settings in the client side "firebird.conf" This
412 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
413 Each line of the string list should be a setting in the same format as "firebird.conf".
414 For example "WireCompression = true" in order to request wire compression on the client side.
416 Note: explicit settings in the client side "firebird.conf" appear to take precedence
417 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
418 also require a compatible setting in the server side "firebird.conf". For example
419 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
420 compression to be used.
422 Whether or not WireCompression or WireCrypt are in use can be checked using the information
423 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
424 ibx/examples/dbinfo for examples of how to display this information.
426 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
427 is a "convenience" property. If set the "WireCompression=true" is added to the
428 ConfigOverrides. If unchecked then this setting is removed.
430 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
431 not "INT64".
433 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
434 These are:
435 property TimestampFormat: string;
436 property DateFormat: string;
437 property TimeFormat: string;
439 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
440 DATETIME and TIME. The format strings use the standard FPC date/time format
441 characters (see
443 If any of the above properties are set to an empty string, then the locale default
444 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
445 locale default is extended by appending '.zzz' to include milliseconds.
447 TIBCSVDataOut by default sets these properties to the empty string, while the other
448 two use: ' hh:nn:ss.zzz', '' and 'hh:nn:ss.zzz' respectively.
450 5. New published property for TIBCSVDataOut:
451 property QuoteStrings: boolean (default true)
453 If false then strings are unquoted, otherwise, the QuoteChar property value is
454 used to delimit each and every string in the output.
456 6. New published properties for TIBCSVDataOut:
457 property FieldSeparator: string;
458 property HeaderSeparator: string;
460 Respectively, these provide the separator character(s) used to separate fields
461 in data and header rows. Both default to ','.
463 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
464 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
465 property OnFormatTextString;
467 This event handler can be used to process text strings before they are included
468 in the output e.g. to replace unprintable characters with alternative strings.
469 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
471 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
472 Uses "FindParam" if in order to find out if a parameter with a given name exists
473 and without raising and exception if it does not.
475 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
476 consistency with SQL queries.
478 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
479 When true, SQL statement parameter names are parsed case sensitive. Note for
480 TIBDataSet only applies to Select query.
482 11. IBEvents: removing a TIBEvent component from a form should no longer result in
483 an IDE exception.
485 12. LocalDBSupport: initial database creation should now work correctly
486 when the schema source is an sql file.
488 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
489 when defined, this handler will be called by the internal TIBXScript during
490 initial database creation when the schema source is an sql file and may be used
491 to provide a visual indication of progress in console mode.
493 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
494 to true while a new local database is being created and its schema populated.
495 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
496 when the database is disconnected/connected during the create DB procedure.
498 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
499 are now always ignored and replaced by the user name and password provided as
500 the login parameters for the TIBDatabase referenced from the TIBXScript. The
501 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
502 completely ignored if this property is true.
504 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
505 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
506 ImageIndex and SelectImageIndex values on AddNode.
508 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
509 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
510 the same database connection.
512 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
513 if provided, this should be an conditional SQL expression suitable for
514 including in an SQL Select statement "where" clause. If non-empty and the
515 "Filtered" property is true then the SQL expression provided as the value of
516 the "Filter" property is "ANDed" with any existing condition statement
517 in the SQL statement's "Where" clause.
519 If the "Filter" property is set at run time, the "Filtered" property is true
520 and the dataset is already open, then the dataset is closed and re-opened automatically.
522 The "Filter" condition may include IBX style parameters. In which case, their
523 value must be set by the dataset's "OnBeforeOpen" event handler.
525 This is a public property for TIBDataSet and TIBQuery query and intended for
526 use at run time.
528 Note: The property is a published property of TIBTable. The TIBTable functionality
529 is unaffected by this change.

533 1. Remove need to check for IsMultiThread by providing access to GUI timers via
534 IBGUIInterface. Note: master/detail delay timer does not apply to console
535 mode apps.
537 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
538 statement. This avoids problems if "Execute Block" is used as the Query.
540 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
541 internal SQL tokeniser routines.
543 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
544 as a select statement, with or without CTEs.
546 5. IBSQLParser: parser now recognises the "ROWS" clause.
548 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
549 internal SQL tokeniser routines.
551 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
552 being raised for valid set statements processed by a data formatter.
554 8. New published property for TIBDatabase and TIBXServicesConnection. This is
555 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
556 the path of the Firebird Library used by the database/services connection.
558 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
559 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
560 services connection.
562 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
563 or param name is not a valid SQL identifier.
565 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
566 view of whether the text box should be editable when no DataSource is specified.
567 TIBLookupComboEditBox has been updated to workaround this problem. As long as
568 ReadOnly is false, the text box is editable when no DataSource is specified.
570 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
571 the FBLIB environment variable. If you do not want to permit this then you
572 must modify the Register procedure in the design/IBDBReg.pas unit to remove
573 this setting.
575 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
577 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
578 Utf8EscapeControlChars
580 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
582 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
583 all previous copies of the IBX source code tree before installing this release.
585 The IBX packages used by most users have not changed, with one exception. The
586 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
587 to use the IBServices unit in your applications, please add the iblegacyServices
588 to the list of dependencies. To do this, open the Project Inspector and select
589 Add->New Requirement and select "ibLegacyServices" from the list of available
590 packages.
592 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
593 the IBServices unit providing what is intended to be a clearer and easier to
594 use set of IB Services components. See Chapter 10 of the IBX User Guide for
595 more information and the guide to "Firebird Service Management Using IBX".
596 As indicated above, the legacy services components are still available and
597 provided in a separate package. There is no need to update working applications
598 using the older versions except for an additional package dependency.
600 2. The IBX packages and source code tree have been re-organised in an attempt to
601 finally get rid of the "duplicate ppu" warnings. This re-organisation should
602 not affect existing users. Section 2.3 of the IBX User Guide describes the
603 new set of IBX packages.
605 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
606 updated to use the new Services API components.
608 4. The iblocal package has been updated to use the new Services API components.
610 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
611 TIBXSecurityService. It had been wrongly classified in the previous version
612 as a per database configuration item. It is global to a server and hence
613 correctly positioned as part of the Security Package. In the DBAdmin example,
614 the setting has moved to the mappings page.
616 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
617 are ignored.
619 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
620 closed before the database is dropped. Before and After Disconnect event handlers
621 are also fired.
623 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
624 is started and not just the first time.
626 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
627 depenendency with comp type.
629 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
631 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
632 then this is recognised and not ignored.
634 12. TIBDataSet, TIBQuery, TIBTable: additions:
635 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
636 function GetPerfStatistics(var stats: TPerfCounters): boolean;
637 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
639 GetRowsAffected returns the affected row counts from the last insert/update/delete
640 if EnableStatistics = true then GetPerfStatistics returns the current stats
641 counters for the select query. Note: stats accumulate after each fetch from
642 the database. To get total query cost after open, call the "Last" method
643 and then GetPerfStatistics.
645 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
647 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
648 in parenthesises.
650 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
651 SQL identifiers are always delimited by double quotes. If false, then they are
652 only delimited if the identifier is a reserved word, contains lower case or special
653 characters. Set this property to true to retain previous behaviour.
655 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
656 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
658 16. TIBDataSet, TIBQuery, TIBTable: addition:
659 property MasterDetailDelay: integer {defaults to zero}
661 When non-zero and the dataset is a detail table referencing a master table
662 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
663 then a synchronisation delay is added (in milliseconds) between the master
664 row changing and the detail dataset being re-opened. If the master dataset
665 is scrolled before the delay expires then the delay is reset. This can be used
666 to avoid performance overheads when scrolling through a large master dataset.
668 Note: uses fptimer and hence requires a thread manager. Under Linux the
669 chreads unit must be included in your project. TTimer is not used in order
670 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
672 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
673 with Extract Option eoDatabase.
675 18. TIBLookupComboEditBox: Workaround added for
676 When a deLayoutChanged event is reported on the ListSource dataset, the
677 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
678 relationship with the control's datasource (master).
680 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
682 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
683 stubs. Pedantic fix really, as procedures output in dependency order anyway.
685 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
686 DDL (Firebird 3 and later only).
688 22. TIBLookupComboBox Autocomplete Fixes:
689 i. Only appended text is now selected after autocomplete.
690 ii. Uppercase keys no longer ignored for autocomplete.
691 iii. Retain Prefix case is now honoured correctly.
692 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
693 before autocomplete performed. i.e. behaviour now the same as when
694 no DataSource assigned.
696 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
697 between SQL statements.
699 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
700 ObjectNames are converted to upper case before matching against metadata object
701 names, unless the objectname is delimited by double quotes, in which case, the
702 double quotes are removed and the remaining string is used (unmodified) to match
703 against the metadata object name.
705 If true then the ObjectName is used as is without modification and matched
706 against the metadata object name. No attempt is made to remove double quotes.
708 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
709 with eoTrigger, these extract types can be used to select only Database Triggers,
710 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
712 26. TIBXScript: If an exception occurs during the processing of a statement, the
713 statement separate character is now reset to the default (';').
715 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
717 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
718 a commit or reconnect statement and instead activated only when next SQL statement
719 is executed.
721 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
723 30. TIBXScript: case insensitive regex now used when matching statements instead of
724 converting statement to upper case.
726 31. TIBExtract: metadata comments now supported. New published property
727 IncludeMetaDataComments (default true). If true then metadata comments included
728 in extracted DDL. New Extract Object member eoComments. This may be used with
729 ExtractObject method to list all metadata comments.
731 32. TIBExtract: ListObjectNames method added.
733 33. Updated Database component editor to support additional connection string
734 types.
736 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
744 1. IBExtract: Identity columns - add additional check for null column for generator name.
746 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
747 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
748 information). However, this is also a very useful mechanism for returning updated computed by
749 column values. Values returned as a result of executing an Insert or Update statement
750 replace existing values in the current row for each corresponding column.
752 Previously, if a dataset's select query included read only (computed by) fields then
753 an automatic row refresh was performed after an insert or update query had been processed,
754 irrespective of the setting of the "ForcedUpdates" property. This has changed such
755 that an automatic refresh is no longer performed if an insert or update query contains
756 a returning clause that updates one or more fields on the current row. A full row
757 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
758 field values and the select query contains read only fields. Use of Insert/update
759 returning should be significantly more efficient than executing a refresh query.
761 This behaviour change is intended to be backwards compatible and there should be no need to change
762 existing programs, other than to improve performance by using the new capability.
764 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
765 they are called when the dataset row is being deleted, there is no value in
766 updating the current record from the query result. Instead, a new event handler
767 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
768 an OnDeleteReturning event handler is provided then it is called with the IResults returned
769 by the query. The event handler can then interrogate the query results and
770 perform whatever action is necessary. For example to confirm, to the user,
771 the deletion of a row with the returned values.
773 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
774 any Computed By or Identity Columns. The IBTables example has been updated to
775 illustrate the computation of the employee Full Name on update.
777 5. TIBTable: The GeneratorField property is now published.
779 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
780 When InsertSQL is generated, the Identity columns are not included in the list of values to
781 be inserted. A RETURNING clause is added to the insert statement to return the value of
782 each Identity column after the insert is executed.
784 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
785 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
786 Insert..Returning clause.
788 8. TIBGenerator: small performance improvement by not preparing query each time
789 a new value is generated.
791 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
793 10. Property editors will now sync table name to a System Table when "Include System
794 Tables" is selected and the query is for a System Table.
796 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
797 values are no longer converted to milliseconds from TDateTime and then back again
798 to TDateTime (the conversion to milliseconds is the default TDataset approach).
800 12. Property Editors handling of Stored Procedures.
801 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
802 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
803 query).
804 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
806 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
807 can be used to select a package. If non-empty, the stored procedure name is
808 expected to be a stored procedure defined in the specified package and the
809 generated SQL will be as required for a stored procedure located in a package.
811 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
812 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
813 which a stored procedure can be selected. With no package name selected, non-package
814 stored procedures are listed.
816 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
817 for password on reconnect.
819 16. TIBDatabase: use IAttachment for connection default character set id, code page
820 and character set name.
822 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
823 DB info lookups"
825 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
827 19. Add a property Editor for TIBUpdate.RefreshSQL.
829 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
830 parameters. This stops an exception being raised when the field cannot be
831 located in the record buffer.
833 21. Property Editors now automatically include System Tables when opened and when the query table
834 is a System Table.
836 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
837 This avoids errors due to a stale SQRB or SRB being used for the next query.
839 23. IBServices: Service attach parameters now include "expected_db". This is used to
840 add the SPB item isc_spb_expected_db. This names a database using
841 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
842 database. examples/services re-written to illustrate use of "expected_db".
844 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
845 This avoids truncated backups when the server returns a timeout (busy) response.
847 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
849 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
850 databasenames. These are respectively expanded to the local system's temp directory
851 (including trailing delimiter) or to a prescribed data directory (including
852 trailing delimiter). Under Unix systems the data directory is a hidden directory
853 in the user's home directory. The hidden directory name is either the string returned
854 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
855 Under Windows, the directory is the same as the Data Directory as decribed
856 above but instead prefixed by the User's application data path. These may be
857 used to improve application portability for Personal Databases.
859 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
860 this has not worked for a long time and is not useful either. FieldDefs should be
861 managed using the Fields Editor as with any other dataset. To access the fields
862 editor for a TIBTable component, double click on the component. The fields editor
863 is then displayed.
865 28. TIBDatabaseInfo: new properties/function
866 * DateDBCreated (returns date/time database created)
867 * TransactionCount (returns no. of active transactions)
868 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
869 * PagesFree (Firebird 3 or later)
870 * PagesUsed (Firebird 3 or later)
871 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
872 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
874 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
876 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
878 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
879 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
881 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
882 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
883 firing during backup and restore.
885 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
886 for verbose output using the new property "StatisticsRequested".
887 see
889 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
891 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
892 palette. This uses the online validation feature added in Firebird 2.5. The
893 services's properties enable inclusion/exclusion of tables and indexes using
894 regular expressions. See.
897 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
898 option on a database.
900 37. TIBCustomService: Assign method implemented to allow copying of service login
901 context between service API components. "Detach" method now only detaches
902 service when last reference to the service interface detaches. Tidy up of
903 code for SetActive and Attach methods including password hiding.
905 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
906 and used to determine the auth method and protocol used for the connection.
908 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
909 a Create Database Statement generated by IBX.
911 40. All IBServices now have an additional published property "PortNo". This may
912 be set to a non-standard port number when necessary. If zero then the default
913 port number is used.
915 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
916 and not just the mouse.
918 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
920 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
921 image index and selected image index for each node to be set from a database field.
923 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
924 then database schema includes grants to all users. If not present then the
925 only user grants included are those to User PUBLIC.
927 45. TIBTreeView: performance improvement. When expanding include both expanded node
928 and child nodes in dataset.
931 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
933 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
934 changes.
936 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
937 Bug could result in truncated multi-byte character set values.
939 3. Changes consequential on moving fbintf character set utility functions from
940 IFirebirdAPI to IAttachment.
942 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
944 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
945 results in autocomplete ignoring prefix text.
947 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
948 entering a new name into the text box.
950 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
951 Firebird rather than recomputing it.
953 8. Property Editor positioning tidy up: All IBX Property editors should now be
954 screen centre. Previously some were "poDesigned" which may be inappropriate
955 for multi monitor desktops.
957 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
959 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
960 a transaction and always reset the object.
962 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
964 13. TIBXScript: Allow for override of database filename in Create Database statements.
966 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
967 to a gbak format archive.
969 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
971 16. IBLocaldb: Drop database if error creating an empty database.
973 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
974 unless selected node not in current dataset.
976 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
977 to TIBCustomService, and IBlocalDB code tidy up.
979 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
980 behaviour due to uninitialised variable.
982 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
983 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
985 21. IBSQL: When Database changed ensure that all resources are freed.
987 22. IBCustomDataset: When database changed ensure that queries an unprepared.
989 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
990 * Line Wrap on SQL Token boundaries (on user command)
991 * auto-complete table names in drop down list of table names
992 * Double click on tablename or field name adds to SQL text
994 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
996 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
997 TVariantArray. Seems to avoid memory corruption in Windows (probably a
998 workaround for a problem in fpc 3.0.4 win64).
1000 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
1002 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
1004 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
1006 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
1007 include remote system name.
1009 2. TIBExtract: No longer include comment header and COMMIT statement for empty
1010 tables when data included in output.
1012 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
1013 and timing information to be written to stdout. This may be used to locate
1014 performance bottlenecks.
1016 4. SQLParser: only call "OnChanging" event handler when value is different.
1018 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
1020 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
1021 that BindFields is called when the query is next activated. Avoids FieldName
1022 not found error.
1024 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
1025 purpose and allows the programmer to define any action they want for Update, Insert
1026 or Delete. This may be complex SQL (similar to a Trigger), application specific
1027 filtering of updates, or use of statements such as Grant or Revoke instead of
1028 normal DML. See User Manual for more information.
1030 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
1032 1. TIBEvents: Fix uninitialised variable that could result in lost events.
1034 2. TIBExtract: Added support for FB3 "USAGE" privilege.
1036 3. TIBExtract: data formatted as Charset set "octets" is now output using
1037 hexadecimal notation.
1039 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
1040 using a simple XML format.
1042 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
1043 grants to these objects.
1045 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
1046 dependency problems restoring complex databases.
1048 7. TIBXScript: This component has been restructured to allow for the processing of
1049 embedded XML in INSERT statements and to support interactive sources in addition
1050 to non-interactive data sources such as files.
1052 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
1054 9. TIBXScript: ISQL compatiable Set statements are now supported:
1062 SET NAMES <character set>
1064 10. IBVersion unit added to hold current IBX Version Number information.
1066 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
1067 and domain definitions.
1069 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
1070 fully supported.
1072 13. TIBExtract: when a database dump includes data, the generator values are now also set.
1074 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
1076 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
1078 See also doc/IBX4LazarusGuide.pdf for important information on
1079 upgrading to IBX2.
1081 1. Size property of TIBStringField is now the width in characters of the field
1082 and not the byte length. This applies only to multi-byte character sets such
1083 as UTF8. The original approach aligned with TStringField. However, the TStringField
1084 code is not recognised as a bug and hence this change to align the behaviour.
1085 The TStringField change is expected in fpc 3.2.0.
1087 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
1088 true (default) then Size property value saved in the lfm is ignored. Size is
1089 always set from the dynamic information read from the database. It is unclear
1090 why anyone would want to override this and set Size to false.
1092 3. ibxscript: should now handle correctly a Case..End statement within a procedure
1093 block.
1095 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
1096 exist when an attempt is made to connect to it (run time only) then an attempt
1097 is made to create the database.
1099 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
1100 has been successfully created as a result of a call to CreateDatabase or when
1101 creating a database after it was found not to exist.
1103 6. DBControlGrid: a race condition could result in the wrong row image being
1104 written to the cache. This has been avoided by a trip round the message
1105 loop before rendering the row image.
1107 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
1108 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
1109 known to risk corrupt rendering of row images when the control is first
1110 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
1111 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
1113 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
1114 a TDateEdit control located on an editor panel.
1116 9. TIBExtract: brought up-to-date plus many bug fixes.
1118 10. DBControlGrid: Removed memory leak when updating rows.
1120 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
1122 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
1124 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
1125 when target codepage is CP_NONE. This is a workaround for
1128 2. DBLog option removed from TIBStatisticalService - not supported by server
1129 since Firebird 1.5.
1131 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
1132 similar.
1134 4. IBCodePage: updated mapping between codepages and character id.
1136 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
1137 Firebird. Character sets with a char width of two are not UTF16.
1139 6. Strings received from the database are now always transliterated into UTF8
1140 regardless of the database character set or connection character set. This
1141 is for compatibility with the LCL.
1143 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
1145 1. IBBlob: Defer reading of blob until read method called. This avoids having to
1146 read in an entire blob just to get the size of the blob. General performance
1147 improvement when opening datasets containing blobs.
1149 2. Clearing a Blob now sets the corresponding field's modified flag.
1151 3. IBLookupCombo: When not performing auto-complete, original query sort order
1152 is now used.
1154 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
1155 determined.
1157 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
1159 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
1160 lazarus 1.6.0
1162 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
1163 compilation error.
1165 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
1167 1. No character set specified for connection: when a text blob is retrieved, the
1168 character set is determined by looking up the native character set using then
1169 Firebird API. Otherwise a text mode blob is assumed to have the same character
1170 set as the connection.
1172 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
1173 for Login Dialog returing a change to the database path.
1175 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
1176 to be changed from that given in the TIBDatabase/TIBServer component and for the
1177 entered value to be saved on a project specific basis (design time only).
1179 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
1180 column fieldname. If they are the same then it is acts as a look up for the KeyValue
1181 Otherwise, it sets the column text to the selected ListField Value.
1183 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
1184 column width.
1186 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
1187 and a case insensitive search is requested.
1189 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
1190 or column ListSource.
1192 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
1193 unprepare) when closing and the text has not changed.
1195 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
1196 Less likely to cause a cursor re-use error on Windows.
1198 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
1199 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
1201 11. TIBTreeView: Guard against nil destination on record changed
1203 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
1204 string type with the code page set to reflect the returned field encoding after
1205 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
1206 earlier versions.
1208 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
1209 will now result in transliteration to the code page specified for the Firebird driver
1210 if the assigned string has a different code page. FPC 3.0.0 onwards only.
1212 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
1213 is ignored and the lc_ctype value, when the database is opened, is set to align with
1214 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
1215 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
1216 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
1217 the GETACP is used to determine the Windows code page.
1219 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
1220 name used as the lc_ctype when the database was opened. Only valid while the
1221 Database is connected.
1223 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
1224 id that corresponds to the DefaultCharSetName.
1226 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
1228 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
1229 path is given and database attach fails due to access permission issues on the
1230 temp directory or security database, then the attach is retried with "localhost:"
1231 prefixing the databasename. This should avoid problems when the database has to
1232 be accessed by a local (e.g. classic) server and libfbembed is used.
1234 2. Windows: revised search order for Firebird DLL:
1235 i. The Firebird Embedded Server in the application Directory.
1236 ii. If the FIREBIRD environment variable is set then the directory this
1237 points to is searched for the FB Client DLL and then then underlying
1238 "bin" directory.
1239 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
1240 is used to locate the Firebird installation directory and the underlying
1241 "bin" directory is searched for the FB Client DLL.
1242 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
1243 are searched for the FB Client DLL.
1244 v. The PATH Environment variable is used to search for the FB Client DLL.
1245 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
1247 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
1248 See doc/readme.scriptengine and example applications.
1250 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
1251 simplify the use of the embedded firebird server on both Linux and Windows platforms.
1252 See dpc/readme.localdatabase and example applications.
1254 5. IBDynamicGrid: Reordering on column header click should now also work for
1255 dynamic columns.
1257 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
1258 between incrementing/decrementing the lock count and signalling the event.
1260 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
1262 1.3.2 was never formally released and only made available as beta copies.
1264 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
1266 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
1268 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
1270 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
1271 i.e. when it is a calculated field
1273 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
1274 This problem was due to a race condition between recalculating row heights and
1275 determining which row was selected by the mouse click. The row height calculation
1276 is now deferred by an extra trip round the message loop allowing the row to
1277 be always calculated on the current grid layout rather than risking it being
1278 calculated on the grid layout after the expanded row has been shrunk.
1280 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
1281 Windows.
1283 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
1284 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
1285 to be determined at runtime. See doc/readme.charactersets.html.
1287 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
1288 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
1290 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
1291 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
1292 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
1294 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
1295 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
1296 implies no truncation.
1298 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
1300 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
1301 (avoids "Not in Edit Mode" error).
1303 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
1305 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
1306 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
1308 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
1310 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
1312 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
1314 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
1316 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
1318 1. OnCloseUp Event Handler added to TDBLookupProperties
1320 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
1321 problem with row size when exception is called.
1323 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
1325 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
1326 in a TCustomComboBox and ignores return key if in a TCustomMemo
1328 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
1329 keyed in i.e. when autocomplete not performed
1331 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
1332 console mode applications with all LCL required functions (builtin dialogs and
1333 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
1334 not included in your project, IBX should compile and link with a console mode program.
1335 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
1336 console mode application or the IDE will automatically assume that your
1337 application is GUI based. Instead, you should include the ibexpressconsolemode package.
1339 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
1340 to use the built in dialogs and cursor management. IBDialogs is
1341 included by default if "ibexpress" is in your project source's "uses" clause.
1342 This should be the case for all projects created through the IDE. This is why
1343 you do not want to add the ibexpress package to console mode applications. The
1344 ibexpressconsolemode package has been created to allow console mode programs
1345 to avoid adding LCL dependencies when using IBX, while still having the
1346 unit search paths set up correctly.
1348 Existing users should check to ensure that the "ibexpress" unit is included in
1349 each project's source file (*.lpr).
1351 You may find that in order for the IDE to recognise that ibexpressconsolemode
1352 exists, you have to first open the package in the IDE and then close it. This
1353 adds it to the most recently accessed packages list. To make it permanently
1354 available, add the package name to lazarus' file.
1356 Thanks to Julio Jiménez for suggesting support of console mode.
1358 7. SQL Parser can now accept quoted strings that include new lines
1360 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
1361 of text on start of edit. This is particularly useful when tabbing to a
1362 column and then inserting text.
1364 9. New Examples provided for IB Services and ISQLMonitor.
1366 10. Fix error when writing to blob streams that recorded only the last buffer
1367 write in the blob stream. In most cases, this did not cause a problem as the
1368 IB Blob Stream is written in a single write. However, with the TDBImage, write
1369 of a graphic type prefix was lost which caused a problem when the image could
1370 not be automatically recognised.
1372 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1373 already open" errors due to random numbers used for the cursor name being identical.
1375 12. IBTable: corrected error that could result in an "Index out of bounds" error
1376 when opening the table and the Primary Key is the last or only column in the
1377 table. Thanks to Rick Hoover for the fix.
1379 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1380 of "UTF-8", and update list of available database character sets. Existing
1381 users should check the current lc_ctype setting in their applications.
1383 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1385 1. Firebird Services: avoid List Index error when opening a service with an
1386 empty Params property.
1388 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1389 Link now set up in Loaded method - avoids occasional failure to apply
1390 SQL markup on initial open.
1392 3. "Employees" example performance improvements when scrolling.
1394 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1395 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1396 random image cached).
1398 5. DBControlGrid: Should now react to changes in panel height at run time.
1400 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1401 even when further rows exist.
1403 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1404 always be derived from panel height and setting this property can cause confusion.
1405 Note for existing projects: to avoid a missing property error at run time,
1406 each form using the DBControlGrid must be opened, updated and saved in the IDE
1407 in order to remove the property value from the lfm.
1410 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1412 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1413 call Prepare before setting parameter values.
1415 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1417 3. Code tidyup and more robust handling of dsql information result vector.
1419 4. Support for centralised handling of transaction status changes. TIBTransaction
1420 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1421 and "AfterExecQuery". The first three are called after the same event is called
1422 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1423 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1424 enable monitoring of transaction status changes for a given transaction to be
1425 handled in a single place. For example, when a change to the dataset occurs
1426 an indicator can be set that shows the user that in order to save changes,
1427 the transaction should be committed. Rather than doing this per dataset, this
1428 can now be done per transaction.
1430 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1431 the dataset is scrolled. However, any changes to the current row are, by default,
1432 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1433 have a new property "DataSetCloseAction" that adds automatic posting of changes
1434 on dataset close. If this property is set to dcDiscardChanges (default) then the
1435 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1436 then IBX will attempt to post any unsaved changes before the dataset is closed
1437 (and after the BeforeClose event handler is called). The exception is when the
1438 dataset is being closed as a result of a transaction rollback. In this case,
1439 no action is taken and any unsaved changes are discarded. This avoids both
1440 unnecessary overhead and the risk that a validation error may occur in the Post
1441 raising an exception and thereby preventing a rollback.
1443 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1444 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1445 width. Display Widths are now corrected by dividing by the max byte width per character.
1446 For UTF8 character sets, the byte width is four and hence the Display Width will be
1447 the byte width divided by 4. The byte width of each character set is determined
1448 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1449 system table. (see also
1451 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1453 8. IBLookupComboEditBox: List should now always be restored to full list when the
1454 control loses focus. Default Key press default interval reduced to 200ms.
1456 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1457 when dataset rows are less than visible rows.
1459 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1460 does not exist or DataSet is empty. More responsive on dataset open. New event
1461 OnRestorePosition. Column sort disabled if no header row.
1463 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1464 while dataset state is dsInsert. Avoids posting errors.
1466 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1467 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1469 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1471 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1472 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1473 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1474 always "posts" the current record regardless or whether or not it may be more appropriate
1475 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1476 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1477 as the first action of the "Post" method and allows the handler to convert the Post
1478 into a Cancel if that is the appropriate action on moving to a different row. This is
1479 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1480 raised here, but it may still be more appropriate to validate a post and signal
1481 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1483 15. On Unix derived systems, the Firebird library name can now be given as a colon
1484 separated list. Each library name on the list is tried in turn, in left to right
1485 order with the first found being used as the firebird library. By default, on Linux,
1486 the library name list is ''. This can be
1487 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1489 Note: when using the, if you prefix the database name with "localhost:"
1490 then it will still attempt to access the database via the Firebird Server and will
1491 require a username and password. If only the pathname is given, then the username
1492 and password should be omitted and the unix file permissions are used to grant
1493 access.
1495 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1497 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1498 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1499 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1500 corresponds to a row of the linked DataSource. Any data aware control on the
1501 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1503 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1504 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1505 takes place during database access. This may be useful when there are performance issues with
1506 the change of cursor. Setting the property to false suppresses the change of cursor.
1508 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1509 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1510 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1511 making all changes permanent immediately rather than when the transaction is explicitly
1512 committed.
1514 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1515 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1517 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1519 Development version only.
1521 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1523 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1524 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1525 "Where" and "Having" clauses to implement user specified filters of arbitrary
1526 complexity.
1528 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1529 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1530 These are:
1532 - TIBLookupComboEditBox
1533 - TIBDynamicGrid
1534 - TIBTreeview
1536 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1537 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1538 to revise the available list and restrict it to items that are prefixed by the
1539 typed text (either case sensitive or case insensitive). Autoinsert allows a
1540 newly typed entry to be added to the list dataset and included in the available
1541 list items.
1543 TIBDynamicGrid is a TDBGrid descendent that provides for:
1544 - automatic resizing of selected columns to fill the available row length
1545 - automatic positioning and sizing of a "totals" control, typically at the
1546 column footer, on a per column basis.
1547 - DataSet resorting on header row click, sorting the dataset by the selected column.
1548 A second click on the same header cell reversed the sort order.
1549 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1550 is automatically expanded and a panel superimposed on it. The panel can have any
1551 number of child controls, typically data aware controls with the same datasource
1552 as the grid allowing for editing of additional fields and more complex editors.
1553 - Reselection of the same row following resorting.
1554 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1555 Its properties are specified on a per column basis and allows for one or more
1556 columns to have their values selected from a list provided by a dataset.
1557 Autocomplete and autoinsert are also available. The existing picklist editor
1558 is unaffected by the extension.
1560 TIBTreeView is a data aware TCustomTreeView.
1562 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1563 zero scale will no longer return an error. An Int64 will be returned instead.
1565 4. TIBTransaction now has events for Before and After Transaction End and a new function
1566 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1568 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1569 repeated multiple times.
1571 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1572 check used to get in the way of using Stored Procedures, and "Update or Insert"
1573 statements.
1575 7. Insert, Modify and Delete property Editors now support Query Generation from
1576 Stored Procedures.
1578 8. Three new examples illustrate the use of the new IB Controls
1581 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1583 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1584 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1585 Gabor Boros for reporting this problem and for testing the improvements).
1587 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1588 See readme.field+param.names in the doc folder.
1590 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1591 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1593 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1595 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1596 actions.
1598 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1599 thanks to Yuriy Kopnin for pointing this out).
1601 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1603 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1604 for both fields and parameter setting.
1606 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1607 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1609 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1610 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1612 11. TIBTable now has a property editor for "MasterFields"
1614 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1615 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1617 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1618 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1621 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1623 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1625 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1627 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1628 it is null. This allows for alternative user defined setting of the generator
1630 Many thanks to Julio Jiménez for this fix
1632 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1633 and suggests that the user may have forgotten to install it.
1635 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1637 1. Conditional compilation used to limit registration of TIntegerField to
1638 Lazarus versions less than 1.1
1640 2. When a database connection is created, character set is now by default set
1641 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1642 1250 to 1254.
1645 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1647 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1650 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1652 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1653 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1655 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1656 package is changed to do this (which it should do).
1658 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1660 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1662 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1664 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1666 4. Property editors should now correctly resize.
1668 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1669 (restored original functionality)
1671 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1672 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
