1 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
3 1. Remove need to check for IsMultiThread by providing access to GUI timers via
4 IBGUIInterface. Note: master/detail delay timer does not apply to console
5 mode apps.
7 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
8 statement. This avoids problems if "Execute Block" is used as the Query.
10 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
11 internal SQL tokeniser routines.
13 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
14 as a select statement, with or without CTEs.
16 5. IBSQLParser: parser now recognises the "ROWS" clause.
18 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
19 internal SQL tokeniser routines.
21 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
22 being raised for valid set statements processed by a data formatter.
24 8. New published property for TIBDatabase and TIBXServicesConnection. This is
25 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
26 the path of the Firebird Library used by the database/services connection.
28 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
29 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
30 services connection.
32 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
33 or param name is not a valid SQL identifier.
35 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
36 view of whether the text box should be editable when no DataSource is specified.
37 TIBLookupComboEditBox has been updated to workaround this problem. As long as
38 ReadOnly is false, the text box is editable when no DataSource is specified.
40 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
41 the FBLIB environment variable. If you do not want to permit this then you
42 must modify the Register procedure in the design/IBDBReg.pas unit to remove
43 this setting.
45 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
47 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
48 Utf8EscapeControlChars
50 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
52 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
53 all previous copies of the IBX source code tree before installing this release.
55 The IBX packages used by most users have not changed, with one exception. The
56 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
57 to use the IBServices unit in your applications, please add the iblegacyServices
58 to the list of dependencies. To do this, open the Project Inspector and select
59 Add->New Requirement and select "ibLegacyServices" from the list of available
60 packages.
62 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
63 the IBServices unit providing what is intended to be a clearer and easier to
64 use set of IB Services components. See Chapter 10 of the IBX User Guide for
65 more information and the guide to "Firebird Service Management Using IBX".
66 As indicated above, the legacy services components are still available and
67 provided in a separate package. There is no need to update working applications
68 using the older versions except for an additional package dependency.
70 2. The IBX packages and source code tree have been re-organised in an attempt to
71 finally get rid of the "duplicate ppu" warnings. This re-organisation should
72 not affect existing users. Section 2.3 of the IBX User Guide describes the
73 new set of IBX packages.
75 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
76 updated to use the new Services API components.
78 4. The iblocal package has been updated to use the new Services API components.
80 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
81 TIBXSecurityService. It had been wrongly classified in the previous version
82 as a per database configuration item. It is global to a server and hence
83 correctly positioned as part of the Security Package. In the DBAdmin example,
84 the setting has moved to the mappings page.
86 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
87 are ignored.
89 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
90 closed before the database is dropped. Before and After Disconnect event handlers
91 are also fired.
93 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
94 is started and not just the first time.
96 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
97 depenendency with comp type.
99 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
101 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
102 then this is recognised and not ignored.
104 12. TIBDataSet, TIBQuery, TIBTable: additions:
105 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
106 function GetPerfStatistics(var stats: TPerfCounters): boolean;
107 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
109 GetRowsAffected returns the affected row counts from the last insert/update/delete
110 if EnableStatistics = true then GetPerfStatistics returns the current stats
111 counters for the select query. Note: stats accumulate after each fetch from
112 the database. To get total query cost after open, call the "Last" method
113 and then GetPerfStatistics.
115 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
117 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
118 in parenthesises.
120 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
121 SQL identifiers are always delimited by double quotes. If false, then they are
122 only delimited if the identifier is a reserved word, contains lower case or special
123 characters. Set this property to true to retain previous behaviour.
125 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
126 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
128 16. TIBDataSet, TIBQuery, TIBTable: addition:
129 property MasterDetailDelay: integer {defaults to zero}
131 When non-zero and the dataset is a detail table referencing a master table
132 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
133 then a synchronisation delay is added (in milliseconds) between the master
134 row changing and the detail dataset being re-opened. If the master dataset
135 is scrolled before the delay expires then the delay is reset. This can be used
136 to avoid performance overheads when scrolling through a large master dataset.
138 Note: uses fptimer and hence requires a thread manager. Under Linux the
139 chreads unit must be included in your project. TTimer is not used in order
140 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
142 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
143 with Extract Option eoDatabase.
145 18. TIBLookupComboEditBox: Workaround added for
146 When a deLayoutChanged event is reported on the ListSource dataset, the
147 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
148 relationship with the control's datasource (master).
150 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
152 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
153 stubs. Pedantic fix really, as procedures output in dependency order anyway.
155 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
156 DDL (Firebird 3 and later only).
158 22. TIBLookupComboBox Autocomplete Fixes:
159 i. Only appended text is now selected after autocomplete.
160 ii. Uppercase keys no longer ignored for autocomplete.
161 iii. Retain Prefix case is now honoured correctly.
162 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
163 before autocomplete performed. i.e. behaviour now the same as when
164 no DataSource assigned.
166 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
167 between SQL statements.
169 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
170 ObjectNames are converted to upper case before matching against metadata object
171 names, unless the objectname is delimited by double quotes, in which case, the
172 double quotes are removed and the remaining string is used (unmodified) to match
173 against the metadata object name.
175 If true then the ObjectName is used as is without modification and matched
176 against the metadata object name. No attempt is made to remove double quotes.
178 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
179 with eoTrigger, these extract types can be used to select only Database Triggers,
180 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
182 26. TIBXScript: If an exception occurs during the processing of a statement, the
183 statement separate character is now reset to the default (';').
185 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
187 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
188 a commit or reconnect statement and instead activated only when next SQL statement
189 is executed.
191 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
193 30. TIBXScript: case insensitive regex now used when matching statements instead of
194 converting statement to upper case.
196 31. TIBExtract: metadata comments now supported. New published property
197 IncludeMetaDataComments (default true). If true then metadata comments included
198 in extracted DDL. New Extract Object member eoComments. This may be used with
199 ExtractObject method to list all metadata comments.
201 32. TIBExtract: ListObjectNames method added.
203 33. Updated Database component editor to support additional connection string
204 types.
206 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
214 1. IBExtract: Identity columns - add additional check for null column for generator name.
216 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
217 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
218 information). However, this is also a very useful mechanism for returning updated computed by
219 column values. Values returned as a result of executing an Insert or Update statement
220 replace existing values in the current row for each corresponding column.
222 Previously, if a dataset's select query included read only (computed by) fields then
223 an automatic row refresh was performed after an insert or update query had been processed,
224 irrespective of the setting of the "ForcedUpdates" property. This has changed such
225 that an automatic refresh is no longer performed if an insert or update query contains
226 a returning clause that updates one or more fields on the current row. A full row
227 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
228 field values and the select query contains read only fields. Use of Insert/update
229 returning should be significantly more efficient than executing a refresh query.
231 This behaviour change is intended to be backwards compatible and there should be no need to change
232 existing programs, other than to improve performance by using the new capability.
234 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
235 they are called when the dataset row is being deleted, there is no value in
236 updating the current record from the query result. Instead, a new event handler
237 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
238 an OnDeleteReturning event handler is provided then it is called with the IResults returned
239 by the query. The event handler can then interrogate the query results and
240 perform whatever action is necessary. For example to confirm, to the user,
241 the deletion of a row with the returned values.
243 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
244 any Computed By or Identity Columns. The IBTables example has been updated to
245 illustrate the computation of the employee Full Name on update.
247 5. TIBTable: The GeneratorField property is now published.
249 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
250 When InsertSQL is generated, the Identity columns are not included in the list of values to
251 be inserted. A RETURNING clause is added to the insert statement to return the value of
252 each Identity column after the insert is executed.
254 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
255 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
256 Insert..Returning clause.
258 8. TIBGenerator: small performance improvement by not preparing query each time
259 a new value is generated.
261 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
263 10. Property editors will now sync table name to a System Table when "Include System
264 Tables" is selected and the query is for a System Table.
266 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
267 values are no longer converted to milliseconds from TDateTime and then back again
268 to TDateTime (the conversion to milliseconds is the default TDataset approach).
270 12. Property Editors handling of Stored Procedures.
271 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
272 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
273 query).
274 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
276 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
277 can be used to select a package. If non-empty, the stored procedure name is
278 expected to be a stored procedure defined in the specified package and the
279 generated SQL will be as required for a stored procedure located in a package.
281 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
282 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
283 which a stored procedure can be selected. With no package name selected, non-package
284 stored procedures are listed.
286 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
287 for password on reconnect.
289 16. TIBDatabase: use IAttachment for connection default character set id, code page
290 and character set name.
292 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
293 DB info lookups"
295 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
297 19. Add a property Editor for TIBUpdate.RefreshSQL.
299 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
300 parameters. This stops an exception being raised when the field cannot be
301 located in the record buffer.
303 21. Property Editors now automatically include System Tables when opened and when the query table
304 is a System Table.
306 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
307 This avoids errors due to a stale SQRB or SRB being used for the next query.
309 23. IBServices: Service attach parameters now include "expected_db". This is used to
310 add the SPB item isc_spb_expected_db. This names a database using
311 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
312 database. examples/services re-written to illustrate use of "expected_db".
314 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
315 This avoids truncated backups when the server returns a timeout (busy) response.
317 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
319 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
320 databasenames. These are respectively expanded to the local system's temp directory
321 (including trailing delimiter) or to a prescribed data directory (including
322 trailing delimiter). Under Unix systems the data directory is a hidden directory
323 in the user's home directory. The hidden directory name is either the string returned
324 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
325 Under Windows, the directory is the same as the Data Directory as decribed
326 above but instead prefixed by the User's application data path. These may be
327 used to improve application portability for Personal Databases.
329 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
330 this has not worked for a long time and is not useful either. FieldDefs should be
331 managed using the Fields Editor as with any other dataset. To access the fields
332 editor for a TIBTable component, double click on the component. The fields editor
333 is then displayed.
335 28. TIBDatabaseInfo: new properties/function
336 * DateDBCreated (returns date/time database created)
337 * TransactionCount (returns no. of active transactions)
338 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
339 * PagesFree (Firebird 3 or later)
340 * PagesUsed (Firebird 3 or later)
341 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
342 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
344 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
346 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
348 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
349 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
351 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
352 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
353 firing during backup and restore.
355 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
356 for verbose output using the new property "StatisticsRequested".
357 see
359 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
361 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
362 palette. This uses the online validation feature added in Firebird 2.5. The
363 services's properties enable inclusion/exclusion of tables and indexes using
364 regular expressions. See.
367 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
368 option on a database.
370 37. TIBCustomService: Assign method implemented to allow copying of service login
371 context between service API components. "Detach" method now only detaches
372 service when last reference to the service interface detaches. Tidy up of
373 code for SetActive and Attach methods including password hiding.
375 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
376 and used to determine the auth method and protocol used for the connection.
378 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
379 a Create Database Statement generated by IBX.
381 40. All IBServices now have an additional published property "PortNo". This may
382 be set to a non-standard port number when necessary. If zero then the default
383 port number is used.
385 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
386 and not just the mouse.
388 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
390 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
391 image index and selected image index for each node to be set from a database field.
393 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
394 then database schema includes grants to all users. If not present then the
395 only user grants included are those to User PUBLIC.
397 45. TIBTreeView: performance improvement. When expanding include both expanded node
398 and child nodes in dataset.
401 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
403 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
404 changes.
406 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
407 Bug could result in truncated multi-byte character set values.
409 3. Changes consequential on moving fbintf character set utility functions from
410 IFirebirdAPI to IAttachment.
412 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
414 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
415 results in autocomplete ignoring prefix text.
417 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
418 entering a new name into the text box.
420 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
421 Firebird rather than recomputing it.
423 8. Property Editor positioning tidy up: All IBX Property editors should now be
424 screen centre. Previously some were "poDesigned" which may be inappropriate
425 for multi monitor desktops.
427 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
429 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
430 a transaction and always reset the object.
432 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
434 13. TIBXScript: Allow for override of database filename in Create Database statements.
436 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
437 to a gbak format archive.
439 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
441 16. IBLocaldb: Drop database if error creating an empty database.
443 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
444 unless selected node not in current dataset.
446 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
447 to TIBCustomService, and IBlocalDB code tidy up.
449 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
450 behaviour due to uninitialised variable.
452 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
453 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
455 21. IBSQL: When Database changed ensure that all resources are freed.
457 22. IBCustomDataset: When database changed ensure that queries an unprepared.
459 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
460 * Line Wrap on SQL Token boundaries (on user command)
461 * auto-complete table names in drop down list of table names
462 * Double click on tablename or field name adds to SQL text
464 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
466 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
467 TVariantArray. Seems to avoid memory corruption in Windows (probably a
468 workaround for a problem in fpc 3.0.4 win64).
470 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
472 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
474 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
476 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
477 include remote system name.
479 2. TIBExtract: No longer include comment header and COMMIT statement for empty
480 tables when data included in output.
482 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
483 and timing information to be written to stdout. This may be used to locate
484 performance bottlenecks.
486 4. SQLParser: only call "OnChanging" event handler when value is different.
488 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
490 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
491 that BindFields is called when the query is next activated. Avoids FieldName
492 not found error.
494 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
495 purpose and allows the programmer to define any action they want for Update, Insert
496 or Delete. This may be complex SQL (similar to a Trigger), application specific
497 filtering of updates, or use of statements such as Grant or Revoke instead of
498 normal DML. See User Manual for more information.
500 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
502 1. TIBEvents: Fix uninitialised variable that could result in lost events.
504 2. TIBExtract: Added support for FB3 "USAGE" privilege.
506 3. TIBExtract: data formatted as Charset set "octets" is now output using
507 hexadecimal notation.
509 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
510 using a simple XML format.
512 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
513 grants to these objects.
515 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
516 dependency problems restoring complex databases.
518 7. TIBXScript: This component has been restructured to allow for the processing of
519 embedded XML in INSERT statements and to support interactive sources in addition
520 to non-interactive data sources such as files.
522 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
524 9. TIBXScript: ISQL compatiable Set statements are now supported:
532 SET NAMES <character set>
534 10. IBVersion unit added to hold current IBX Version Number information.
536 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
537 and domain definitions.
539 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
540 fully supported.
542 13. TIBExtract: when a database dump includes data, the generator values are now also set.
544 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
546 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
548 See also doc/IBX4LazarusGuide.pdf for important information on
549 upgrading to IBX2.
551 1. Size property of TIBStringField is now the width in characters of the field
552 and not the byte length. This applies only to multi-byte character sets such
553 as UTF8. The original approach aligned with TStringField. However, the TStringField
554 code is not recognised as a bug and hence this change to align the behaviour.
555 The TStringField change is expected in fpc 3.2.0.
557 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
558 true (default) then Size property value saved in the lfm is ignored. Size is
559 always set from the dynamic information read from the database. It is unclear
560 why anyone would want to override this and set Size to false.
562 3. ibxscript: should now handle correctly a Case..End statement within a procedure
563 block.
565 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
566 exist when an attempt is made to connect to it (run time only) then an attempt
567 is made to create the database.
569 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
570 has been successfully created as a result of a call to CreateDatabase or when
571 creating a database after it was found not to exist.
573 6. DBControlGrid: a race condition could result in the wrong row image being
574 written to the cache. This has been avoided by a trip round the message
575 loop before rendering the row image.
577 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
578 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
579 known to risk corrupt rendering of row images when the control is first
580 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
581 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
583 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
584 a TDateEdit control located on an editor panel.
586 9. TIBExtract: brought up-to-date plus many bug fixes.
588 10. DBControlGrid: Removed memory leak when updating rows.
590 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
592 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
594 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
595 when target codepage is CP_NONE. This is a workaround for
598 2. DBLog option removed from TIBStatisticalService - not supported by server
599 since Firebird 1.5.
601 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
602 similar.
604 4. IBCodePage: updated mapping between codepages and character id.
606 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
607 Firebird. Character sets with a char width of two are not UTF16.
609 6. Strings received from the database are now always transliterated into UTF8
610 regardless of the database character set or connection character set. This
611 is for compatibility with the LCL.
613 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
615 1. IBBlob: Defer reading of blob until read method called. This avoids having to
616 read in an entire blob just to get the size of the blob. General performance
617 improvement when opening datasets containing blobs.
619 2. Clearing a Blob now sets the corresponding field's modified flag.
621 3. IBLookupCombo: When not performing auto-complete, original query sort order
622 is now used.
624 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
625 determined.
627 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
629 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
630 lazarus 1.6.0
632 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
633 compilation error.
635 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
637 1. No character set specified for connection: when a text blob is retrieved, the
638 character set is determined by looking up the native character set using then
639 Firebird API. Otherwise a text mode blob is assumed to have the same character
640 set as the connection.
642 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
643 for Login Dialog returing a change to the database path.
645 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
646 to be changed from that given in the TIBDatabase/TIBServer component and for the
647 entered value to be saved on a project specific basis (design time only).
649 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
650 column fieldname. If they are the same then it is acts as a look up for the KeyValue
651 Otherwise, it sets the column text to the selected ListField Value.
653 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
654 column width.
656 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
657 and a case insensitive search is requested.
659 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
660 or column ListSource.
662 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
663 unprepare) when closing and the text has not changed.
665 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
666 Less likely to cause a cursor re-use error on Windows.
668 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
669 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
671 11. TIBTreeView: Guard against nil destination on record changed
673 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
674 string type with the code page set to reflect the returned field encoding after
675 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
676 earlier versions.
678 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
679 will now result in transliteration to the code page specified for the Firebird driver
680 if the assigned string has a different code page. FPC 3.0.0 onwards only.
682 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
683 is ignored and the lc_ctype value, when the database is opened, is set to align with
684 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
685 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
686 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
687 the GETACP is used to determine the Windows code page.
689 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
690 name used as the lc_ctype when the database was opened. Only valid while the
691 Database is connected.
693 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
694 id that corresponds to the DefaultCharSetName.
696 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
698 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
699 path is given and database attach fails due to access permission issues on the
700 temp directory or security database, then the attach is retried with "localhost:"
701 prefixing the databasename. This should avoid problems when the database has to
702 be accessed by a local (e.g. classic) server and libfbembed is used.
704 2. Windows: revised search order for Firebird DLL:
705 i. The Firebird Embedded Server in the application Directory.
706 ii. If the FIREBIRD environment variable is set then the directory this
707 points to is searched for the FB Client DLL and then then underlying
708 "bin" directory.
709 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
710 is used to locate the Firebird installation directory and the underlying
711 "bin" directory is searched for the FB Client DLL.
712 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
713 are searched for the FB Client DLL.
714 v. The PATH Environment variable is used to search for the FB Client DLL.
715 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
717 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
718 See doc/readme.scriptengine and example applications.
720 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
721 simplify the use of the embedded firebird server on both Linux and Windows platforms.
722 See dpc/readme.localdatabase and example applications.
724 5. IBDynamicGrid: Reordering on column header click should now also work for
725 dynamic columns.
727 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
728 between incrementing/decrementing the lock count and signalling the event.
730 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
732 1.3.2 was never formally released and only made available as beta copies.
734 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
736 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
738 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
740 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
741 i.e. when it is a calculated field
743 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
744 This problem was due to a race condition between recalculating row heights and
745 determining which row was selected by the mouse click. The row height calculation
746 is now deferred by an extra trip round the message loop allowing the row to
747 be always calculated on the current grid layout rather than risking it being
748 calculated on the grid layout after the expanded row has been shrunk.
750 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
751 Windows.
753 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
754 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
755 to be determined at runtime. See doc/readme.charactersets.html.
757 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
758 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
760 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
761 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
762 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
764 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
765 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
766 implies no truncation.
768 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
770 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
771 (avoids "Not in Edit Mode" error).
773 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
775 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
776 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
778 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
780 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
782 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
784 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
786 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
788 1. OnCloseUp Event Handler added to TDBLookupProperties
790 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
791 problem with row size when exception is called.
793 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
795 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
796 in a TCustomComboBox and ignores return key if in a TCustomMemo
798 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
799 keyed in i.e. when autocomplete not performed
801 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
802 console mode applications with all LCL required functions (builtin dialogs and
803 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
804 not included in your project, IBX should compile and link with a console mode program.
805 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
806 console mode application or the IDE will automatically assume that your
807 application is GUI based. Instead, you should include the ibexpressconsolemode package.
809 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
810 to use the built in dialogs and cursor management. IBDialogs is
811 included by default if "ibexpress" is in your project source's "uses" clause.
812 This should be the case for all projects created through the IDE. This is why
813 you do not want to add the ibexpress package to console mode applications. The
814 ibexpressconsolemode package has been created to allow console mode programs
815 to avoid adding LCL dependencies when using IBX, while still having the
816 unit search paths set up correctly.
818 Existing users should check to ensure that the "ibexpress" unit is included in
819 each project's source file (*.lpr).
821 You may find that in order for the IDE to recognise that ibexpressconsolemode
822 exists, you have to first open the package in the IDE and then close it. This
823 adds it to the most recently accessed packages list. To make it permanently
824 available, add the package name to lazarus' file.
826 Thanks to Julio Jiménez for suggesting support of console mode.
828 7. SQL Parser can now accept quoted strings that include new lines
830 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
831 of text on start of edit. This is particularly useful when tabbing to a
832 column and then inserting text.
834 9. New Examples provided for IB Services and ISQLMonitor.
836 10. Fix error when writing to blob streams that recorded only the last buffer
837 write in the blob stream. In most cases, this did not cause a problem as the
838 IB Blob Stream is written in a single write. However, with the TDBImage, write
839 of a graphic type prefix was lost which caused a problem when the image could
840 not be automatically recognised.
842 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
843 already open" errors due to random numbers used for the cursor name being identical.
845 12. IBTable: corrected error that could result in an "Index out of bounds" error
846 when opening the table and the Primary Key is the last or only column in the
847 table. Thanks to Rick Hoover for the fix.
849 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
850 of "UTF-8", and update list of available database character sets. Existing
851 users should check the current lc_ctype setting in their applications.
853 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
855 1. Firebird Services: avoid List Index error when opening a service with an
856 empty Params property.
858 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
859 Link now set up in Loaded method - avoids occasional failure to apply
860 SQL markup on initial open.
862 3. "Employees" example performance improvements when scrolling.
864 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
865 TFrame. Force recaching of selected frame to avoid GTK race (results in a
866 random image cached).
868 5. DBControlGrid: Should now react to changes in panel height at run time.
870 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
871 even when further rows exist.
873 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
874 always be derived from panel height and setting this property can cause confusion.
875 Note for existing projects: to avoid a missing property error at run time,
876 each form using the DBControlGrid must be opened, updated and saved in the IDE
877 in order to remove the property value from the lfm.
880 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
882 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
883 call Prepare before setting parameter values.
885 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
887 3. Code tidyup and more robust handling of dsql information result vector.
889 4. Support for centralised handling of transaction status changes. TIBTransaction
890 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
891 and "AfterExecQuery". The first three are called after the same event is called
892 for an IBCustomDataSet descendent using the Transaction. The fourth is called
893 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
894 enable monitoring of transaction status changes for a given transaction to be
895 handled in a single place. For example, when a change to the dataset occurs
896 an indicator can be set that shows the user that in order to save changes,
897 the transaction should be committed. Rather than doing this per dataset, this
898 can now be done per transaction.
900 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
901 the dataset is scrolled. However, any changes to the current row are, by default,
902 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
903 have a new property "DataSetCloseAction" that adds automatic posting of changes
904 on dataset close. If this property is set to dcDiscardChanges (default) then the
905 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
906 then IBX will attempt to post any unsaved changes before the dataset is closed
907 (and after the BeforeClose event handler is called). The exception is when the
908 dataset is being closed as a result of a transaction rollback. In this case,
909 no action is taken and any unsaved changes are discarded. This avoids both
910 unnecessary overhead and the risk that a validation error may occur in the Post
911 raising an exception and thereby preventing a rollback.
913 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
914 In earlier versions, the Display Width was set to the maximum byte width rather than the character
915 width. Display Widths are now corrected by dividing by the max byte width per character.
916 For UTF8 character sets, the byte width is four and hence the Display Width will be
917 the byte width divided by 4. The byte width of each character set is determined
918 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
919 system table. (see also
921 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
923 8. IBLookupComboEditBox: List should now always be restored to full list when the
924 control loses focus. Default Key press default interval reduced to 200ms.
926 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
927 when dataset rows are less than visible rows.
929 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
930 does not exist or DataSet is empty. More responsive on dataset open. New event
931 OnRestorePosition. Column sort disabled if no header row.
933 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
934 while dataset state is dsInsert. Avoids posting errors.
936 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
937 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
939 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
941 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
942 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
943 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
944 always "posts" the current record regardless or whether or not it may be more appropriate
945 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
946 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
947 as the first action of the "Post" method and allows the handler to convert the Post
948 into a Cancel if that is the appropriate action on moving to a different row. This is
949 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
950 raised here, but it may still be more appropriate to validate a post and signal
951 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
953 15. On Unix derived systems, the Firebird library name can now be given as a colon
954 separated list. Each library name on the list is tried in turn, in left to right
955 order with the first found being used as the firebird library. By default, on Linux,
956 the library name list is ''. This can be
957 overidden by the FBLIB environment variable or the OnGetLibraryName function.
959 Note: when using the, if you prefix the database name with "localhost:"
960 then it will still attempt to access the database via the Firebird Server and will
961 require a username and password. If only the pathname is given, then the username
962 and password should be omitted and the unix file permissions are used to grant
963 access.
965 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
967 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
968 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
969 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
970 corresponds to a row of the linked DataSource. Any data aware control on the
971 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
973 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
974 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
975 takes place during database access. This may be useful when there are performance issues with
976 the change of cursor. Setting the property to false suppresses the change of cursor.
978 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
979 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
980 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
981 making all changes permanent immediately rather than when the transaction is explicitly
982 committed.
984 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
985 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
987 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
989 Development version only.
991 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
993 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
994 This is typically used during an "OnBeforeOpen" event handler to manipulate the
995 "Where" and "Having" clauses to implement user specified filters of arbitrary
996 complexity.
998 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
999 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1000 These are:
1002 - TIBLookupComboEditBox
1003 - TIBDynamicGrid
1004 - TIBTreeview
1006 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1007 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1008 to revise the available list and restrict it to items that are prefixed by the
1009 typed text (either case sensitive or case insensitive). Autoinsert allows a
1010 newly typed entry to be added to the list dataset and included in the available
1011 list items.
1013 TIBDynamicGrid is a TDBGrid descendent that provides for:
1014 - automatic resizing of selected columns to fill the available row length
1015 - automatic positioning and sizing of a "totals" control, typically at the
1016 column footer, on a per column basis.
1017 - DataSet resorting on header row click, sorting the dataset by the selected column.
1018 A second click on the same header cell reversed the sort order.
1019 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1020 is automatically expanded and a panel superimposed on it. The panel can have any
1021 number of child controls, typically data aware controls with the same datasource
1022 as the grid allowing for editing of additional fields and more complex editors.
1023 - Reselection of the same row following resorting.
1024 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1025 Its properties are specified on a per column basis and allows for one or more
1026 columns to have their values selected from a list provided by a dataset.
1027 Autocomplete and autoinsert are also available. The existing picklist editor
1028 is unaffected by the extension.
1030 TIBTreeView is a data aware TCustomTreeView.
1032 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1033 zero scale will no longer return an error. An Int64 will be returned instead.
1035 4. TIBTransaction now has events for Before and After Transaction End and a new function
1036 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1038 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1039 repeated multiple times.
1041 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1042 check used to get in the way of using Stored Procedures, and "Update or Insert"
1043 statements.
1045 7. Insert, Modify and Delete property Editors now support Query Generation from
1046 Stored Procedures.
1048 8. Three new examples illustrate the use of the new IB Controls
1051 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1053 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1054 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1055 Gabor Boros for reporting this problem and for testing the improvements).
1057 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1058 See readme.field+param.names in the doc folder.
1060 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1061 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1063 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1065 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1066 actions.
1068 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1069 thanks to Yuriy Kopnin for pointing this out).
1071 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1073 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1074 for both fields and parameter setting.
1076 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1077 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1079 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1080 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1082 11. TIBTable now has a property editor for "MasterFields"
1084 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1085 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1087 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1088 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1091 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1093 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1095 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1097 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1098 it is null. This allows for alternative user defined setting of the generator
1100 Many thanks to Julio Jiménez for this fix
1102 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1103 and suggests that the user may have forgotten to install it.
1105 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1107 1. Conditional compilation used to limit registration of TIntegerField to
1108 Lazarus versions less than 1.1
1110 2. When a database connection is created, character set is now by default set
1111 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1112 1250 to 1254.
1115 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1117 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1120 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1122 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1123 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1125 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1126 package is changed to do this (which it should do).
1128 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1130 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1132 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1134 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1136 4. Property editors should now correctly resize.
1138 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1139 (restored original functionality)
1141 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1142 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
