1 IBX Change Log version (2.3-3 Build 11336) Fri, 28 Dec 2018 10:04:17 +0000
2
3 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
4 and is used to override the default settings in the client side "firebird.conf" This
5 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
6 Each line of the string list should be a setting in the same format as "firebird.conf".
7 For example "WireCompression = true" in order to request wire compression on the client side.
8
9 Note: explicit settings in the client side "firebird.conf" appear to take precedence
10 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
11 also require a compatible setting in the server side "firebird.conf". For example
12 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
13 compression to be used.
14
15 Whether or not WireCompression or WireCrypt are in use can be checked using the information
16 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
17 ibx/examples/dbinfo for examples of how to display this information.
18
19 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
20 is a "convenience" property. If set the "WireCompression=true" is added to the
21 ConfigOverrides. If unchecked then this setting is removed.
22
23 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
24 not "INT64".
25
26 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
27 These are:
28 property TimestampFormat: string;
29 property DateFormat: string;
30 property TimeFormat: string;
31
32 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
33 DATETIME and TIME. The format strings use the standard FPC date/time format
34 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
35
36 If any of the above properties are set to an empty string, then the locale default
37 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
38 locale default is extended by appending '.zzz' to include milliseconds.
39
40 TIBCSVDataOut by default sets these properties to the empty string, while the other
41 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
42
43 5. New published property for TIBCSVDataOut:
44 property QuoteStrings: boolean (default true)
45
46 If false then strings are unquoted, otherwise, the QuoteChar property value is
47 used to delimit each and every string in the output.
48
49 6. New published properties for TIBCSVDataOut:
50 property FieldSeparator: string;
51 property HeaderSeparator: string;
52
53 Respectively, these provide the separator character(s) used to separate fields
54 in data and header rows. Both default to ','.
55
56 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
57 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
58 property OnFormatTextString;
59
60 This event handler can be used to process text strings before they are included
61 in the output e.g. to replace unprintable characters with alternative strings.
62 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
63
64 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
65
66 9. TIBQuery now uses IBX SQL Parser instead of TParams SQL parser in order to ensure
67 consistency with SQL queries.
68
69 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
70 When true, SQL statement parameter names are parsed case sensitive. Note for
71 TIBDataSet only applies to Select query.
72
73 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
74
75 1. Remove need to check for IsMultiThread by providing access to GUI timers via
76 IBGUIInterface. Note: master/detail delay timer does not apply to console
77 mode apps.
78
79 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
80 statement. This avoids problems if "Execute Block" is used as the Query.
81
82 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
83 internal SQL tokeniser routines.
84
85 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
86 as a select statement, with or without CTEs.
87
88 5. IBSQLParser: parser now recognises the "ROWS" clause.
89
90 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
91 internal SQL tokeniser routines.
92
93 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
94 being raised for valid set statements processed by a data formatter.
95
96 8. New published property for TIBDatabase and TIBXServicesConnection. This is
97 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
98 the path of the Firebird Library used by the database/services connection.
99
100 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
101 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
102 services connection.
103
104 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
105 or param name is not a valid SQL identifier.
106
107 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
108 view of whether the text box should be editable when no DataSource is specified.
109 TIBLookupComboEditBox has been updated to workaround this problem. As long as
110 ReadOnly is false, the text box is editable when no DataSource is specified.
111
112 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
113 the FBLIB environment variable. If you do not want to permit this then you
114 must modify the Register procedure in the design/IBDBReg.pas unit to remove
115 this setting.
116
117 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
118
119 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
120 Utf8EscapeControlChars
121
122 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
123
124 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
125 all previous copies of the IBX source code tree before installing this release.
126
127 The IBX packages used by most users have not changed, with one exception. The
128 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
129 to use the IBServices unit in your applications, please add the iblegacyServices
130 to the list of dependencies. To do this, open the Project Inspector and select
131 Add->New Requirement and select "ibLegacyServices" from the list of available
132 packages.
133
134 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
135 the IBServices unit providing what is intended to be a clearer and easier to
136 use set of IB Services components. See Chapter 10 of the IBX User Guide for
137 more information and the guide to "Firebird Service Management Using IBX".
138 As indicated above, the legacy services components are still available and
139 provided in a separate package. There is no need to update working applications
140 using the older versions except for an additional package dependency.
141
142 2. The IBX packages and source code tree have been re-organised in an attempt to
143 finally get rid of the "duplicate ppu" warnings. This re-organisation should
144 not affect existing users. Section 2.3 of the IBX User Guide describes the
145 new set of IBX packages.
146
147 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
148 updated to use the new Services API components.
149
150 4. The iblocal package has been updated to use the new Services API components.
151
152 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
153 TIBXSecurityService. It had been wrongly classified in the previous version
154 as a per database configuration item. It is global to a server and hence
155 correctly positioned as part of the Security Package. In the DBAdmin example,
156 the setting has moved to the mappings page.
157
158 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
159 are ignored.
160
161 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
162 closed before the database is dropped. Before and After Disconnect event handlers
163 are also fired.
164
165 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
166 is started and not just the first time.
167
168 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
169 depenendency with comp type.
170
171 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
172
173 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
174 then this is recognised and not ignored.
175
176 12. TIBDataSet, TIBQuery, TIBTable: additions:
177 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
178 function GetPerfStatistics(var stats: TPerfCounters): boolean;
179 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
180
181 GetRowsAffected returns the affected row counts from the last insert/update/delete
182 if EnableStatistics = true then GetPerfStatistics returns the current stats
183 counters for the select query. Note: stats accumulate after each fetch from
184 the database. To get total query cost after open, call the "Last" method
185 and then GetPerfStatistics.
186
187 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
188
189 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
190 in parenthesises.
191
192 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
193 SQL identifiers are always delimited by double quotes. If false, then they are
194 only delimited if the identifier is a reserved word, contains lower case or special
195 characters. Set this property to true to retain previous behaviour.
196
197 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
198 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
199
200 16. TIBDataSet, TIBQuery, TIBTable: addition:
201 property MasterDetailDelay: integer {defaults to zero}
202
203 When non-zero and the dataset is a detail table referencing a master table
204 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
205 then a synchronisation delay is added (in milliseconds) between the master
206 row changing and the detail dataset being re-opened. If the master dataset
207 is scrolled before the delay expires then the delay is reset. This can be used
208 to avoid performance overheads when scrolling through a large master dataset.
209
210 Note: uses fptimer and hence requires a thread manager. Under Linux the
211 chreads unit must be included in your project. TTimer is not used in order
212 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
213
214 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
215 with Extract Option eoDatabase.
216
217 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
218 When a deLayoutChanged event is reported on the ListSource dataset, the
219 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
220 relationship with the control's datasource (master).
221
222 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
223
224 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
225 stubs. Pedantic fix really, as procedures output in dependency order anyway.
226
227 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
228 DDL (Firebird 3 and later only).
229
230 22. TIBLookupComboBox Autocomplete Fixes:
231 i. Only appended text is now selected after autocomplete.
232 ii. Uppercase keys no longer ignored for autocomplete.
233 iii. Retain Prefix case is now honoured correctly.
234 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
235 before autocomplete performed. i.e. behaviour now the same as when
236 no DataSource assigned.
237
238 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
239 between SQL statements.
240
241 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
242 ObjectNames are converted to upper case before matching against metadata object
243 names, unless the objectname is delimited by double quotes, in which case, the
244 double quotes are removed and the remaining string is used (unmodified) to match
245 against the metadata object name.
246
247 If true then the ObjectName is used as is without modification and matched
248 against the metadata object name. No attempt is made to remove double quotes.
249
250 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
251 with eoTrigger, these extract types can be used to select only Database Triggers,
252 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
253
254 26. TIBXScript: If an exception occurs during the processing of a statement, the
255 statement separate character is now reset to the default (';').
256
257 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
258
259 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
260 a commit or reconnect statement and instead activated only when next SQL statement
261 is executed.
262
263 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
264
265 30. TIBXScript: case insensitive regex now used when matching statements instead of
266 converting statement to upper case.
267
268 31. TIBExtract: metadata comments now supported. New published property
269 IncludeMetaDataComments (default true). If true then metadata comments included
270 in extracted DDL. New Extract Object member eoComments. This may be used with
271 ExtractObject method to list all metadata comments.
272
273 32. TIBExtract: ListObjectNames method added.
274
275 33. Updated Database component editor to support additional connection string
276 types.
277
278 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
279
280 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
281 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
282 RELEASE.
283
284 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
285
286 1. IBExtract: Identity columns - add additional check for null column for generator name.
287
288 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
289 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
290 information). However, this is also a very useful mechanism for returning updated computed by
291 column values. Values returned as a result of executing an Insert or Update statement
292 replace existing values in the current row for each corresponding column.
293
294 Previously, if a dataset's select query included read only (computed by) fields then
295 an automatic row refresh was performed after an insert or update query had been processed,
296 irrespective of the setting of the "ForcedUpdates" property. This has changed such
297 that an automatic refresh is no longer performed if an insert or update query contains
298 a returning clause that updates one or more fields on the current row. A full row
299 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
300 field values and the select query contains read only fields. Use of Insert/update
301 returning should be significantly more efficient than executing a refresh query.
302
303 This behaviour change is intended to be backwards compatible and there should be no need to change
304 existing programs, other than to improve performance by using the new capability.
305
306 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
307 they are called when the dataset row is being deleted, there is no value in
308 updating the current record from the query result. Instead, a new event handler
309 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
310 an OnDeleteReturning event handler is provided then it is called with the IResults returned
311 by the query. The event handler can then interrogate the query results and
312 perform whatever action is necessary. For example to confirm, to the user,
313 the deletion of a row with the returned values.
314
315 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
316 any Computed By or Identity Columns. The IBTables example has been updated to
317 illustrate the computation of the employee Full Name on update.
318
319 5. TIBTable: The GeneratorField property is now published.
320
321 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
322 When InsertSQL is generated, the Identity columns are not included in the list of values to
323 be inserted. A RETURNING clause is added to the insert statement to return the value of
324 each Identity column after the insert is executed.
325
326 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
327 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
328 Insert..Returning clause.
329
330 8. TIBGenerator: small performance improvement by not preparing query each time
331 a new value is generated.
332
333 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
334
335 10. Property editors will now sync table name to a System Table when "Include System
336 Tables" is selected and the query is for a System Table.
337
338 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
339 values are no longer converted to milliseconds from TDateTime and then back again
340 to TDateTime (the conversion to milliseconds is the default TDataset approach).
341
342 12. Property Editors handling of Stored Procedures.
343 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
344 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
345 query).
346 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
347
348 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
349 can be used to select a package. If non-empty, the stored procedure name is
350 expected to be a stored procedure defined in the specified package and the
351 generated SQL will be as required for a stored procedure located in a package.
352
353 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
354 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
355 which a stored procedure can be selected. With no package name selected, non-package
356 stored procedures are listed.
357
358 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
359 for password on reconnect.
360
361 16. TIBDatabase: use IAttachment for connection default character set id, code page
362 and character set name.
363
364 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
365 DB info lookups"
366
367 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
368
369 19. Add a property Editor for TIBUpdate.RefreshSQL.
370
371 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
372 parameters. This stops an exception being raised when the field cannot be
373 located in the record buffer.
374
375 21. Property Editors now automatically include System Tables when opened and when the query table
376 is a System Table.
377
378 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
379 This avoids errors due to a stale SQRB or SRB being used for the next query.
380
381 23. IBServices: Service attach parameters now include "expected_db". This is used to
382 add the SPB item isc_spb_expected_db. This names a database using
383 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
384 database. examples/services re-written to illustrate use of "expected_db".
385
386 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
387 This avoids truncated backups when the server returns a timeout (busy) response.
388
389 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
390
391 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
392 databasenames. These are respectively expanded to the local system's temp directory
393 (including trailing delimiter) or to a prescribed data directory (including
394 trailing delimiter). Under Unix systems the data directory is a hidden directory
395 in the user's home directory. The hidden directory name is either the string returned
396 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
397 Under Windows, the directory is the same as the Data Directory as decribed
398 above but instead prefixed by the User's application data path. These may be
399 used to improve application portability for Personal Databases.
400
401 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
402 this has not worked for a long time and is not useful either. FieldDefs should be
403 managed using the Fields Editor as with any other dataset. To access the fields
404 editor for a TIBTable component, double click on the component. The fields editor
405 is then displayed.
406
407 28. TIBDatabaseInfo: new properties/function
408 * DateDBCreated (returns date/time database created)
409 * TransactionCount (returns no. of active transactions)
410 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
411 * PagesFree (Firebird 3 or later)
412 * PagesUsed (Firebird 3 or later)
413 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
414 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
415
416 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
417
418 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
419
420 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
421 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
422
423 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
424 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
425 firing during backup and restore.
426
427 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
428 for verbose output using the new property "StatisticsRequested".
429 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
430
431 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
432
433 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
434 palette. This uses the online validation feature added in Firebird 2.5. The
435 services's properties enable inclusion/exclusion of tables and indexes using
436 regular expressions. See.
437 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
438
439 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
440 option on a database.
441
442 37. TIBCustomService: Assign method implemented to allow copying of service login
443 context between service API components. "Detach" method now only detaches
444 service when last reference to the service interface detaches. Tidy up of
445 code for SetActive and Attach methods including password hiding.
446
447 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
448 and used to determine the auth method and protocol used for the connection.
449
450 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
451 a Create Database Statement generated by IBX.
452
453 40. All IBServices now have an additional published property "PortNo". This may
454 be set to a non-standard port number when necessary. If zero then the default
455 port number is used.
456
457 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
458 and not just the mouse.
459
460 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
461
462 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
463 image index and selected image index for each node to be set from a database field.
464
465 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
466 then database schema includes grants to all users. If not present then the
467 only user grants included are those to User PUBLIC.
468
469 45. TIBTreeView: performance improvement. When expanding include both expanded node
470 and child nodes in dataset.
471

473 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
474
475 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
476 changes.
477
478 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
479 Bug could result in truncated multi-byte character set values.
480
481 3. Changes consequential on moving fbintf character set utility functions from
482 IFirebirdAPI to IAttachment.
483
484 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
485
486 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
487 results in autocomplete ignoring prefix text.
488
489 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
490 entering a new name into the text box.
491
492 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
493 Firebird rather than recomputing it.
494
495 8. Property Editor positioning tidy up: All IBX Property editors should now be
496 screen centre. Previously some were "poDesigned" which may be inappropriate
497 for multi monitor desktops.
498
499 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
500
501 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
502 a transaction and always reset the object.
503
504 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
505
506 13. TIBXScript: Allow for override of database filename in Create Database statements.
507
508 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
509 to a gbak format archive.
510
511 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
512
513 16. IBLocaldb: Drop database if error creating an empty database.
514
515 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
516 unless selected node not in current dataset.
517
518 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
519 to TIBCustomService, and IBlocalDB code tidy up.
520
521 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
522 behaviour due to uninitialised variable.
523
524 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
525 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
526
527 21. IBSQL: When Database changed ensure that all resources are freed.
528
529 22. IBCustomDataset: When database changed ensure that queries an unprepared.
530
531 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
532 * Line Wrap on SQL Token boundaries (on user command)
533 * auto-complete table names in drop down list of table names
534 * Double click on tablename or field name adds to SQL text
535
536 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
537
538 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
539 TVariantArray. Seems to avoid memory corruption in Windows (probably a
540 workaround for a problem in fpc 3.0.4 win64).
541
542 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
543
544 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
545
546 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
547
548 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
549 include remote system name.
550
551 2. TIBExtract: No longer include comment header and COMMIT statement for empty
552 tables when data included in output.
553
554 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
555 and timing information to be written to stdout. This may be used to locate
556 performance bottlenecks.
557
558 4. SQLParser: only call "OnChanging" event handler when value is different.
559
560 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
561
562 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
563 that BindFields is called when the query is next activated. Avoids FieldName
564 not found error.
565
566 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
567 purpose and allows the programmer to define any action they want for Update, Insert
568 or Delete. This may be complex SQL (similar to a Trigger), application specific
569 filtering of updates, or use of statements such as Grant or Revoke instead of
570 normal DML. See User Manual for more information.
571
572 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
573
574 1. TIBEvents: Fix uninitialised variable that could result in lost events.
575
576 2. TIBExtract: Added support for FB3 "USAGE" privilege.
577
578 3. TIBExtract: data formatted as Charset set "octets" is now output using
579 hexadecimal notation.
580
581 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
582 using a simple XML format.
583
584 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
585 grants to these objects.
586
587 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
588 dependency problems restoring complex databases.
589
590 7. TIBXScript: This component has been restructured to allow for the processing of
591 embedded XML in INSERT statements and to support interactive sources in addition
592 to non-interactive data sources such as files.
593
594 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
595
596 9. TIBXScript: ISQL compatiable Set statements are now supported:
597 SET SQL DIALECT
598 SET TERM
599 SET AUTODDL
600 SET BAIL
601 SET ECHO
602 SET COUNT
603 SET STATS
604 SET NAMES <character set>
605
606 10. IBVersion unit added to hold current IBX Version Number information.
607
608 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
609 and domain definitions.
610
611 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
612 fully supported.
613
614 13. TIBExtract: when a database dump includes data, the generator values are now also set.
615
616 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
617
618 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
619
620 See also doc/IBX4LazarusGuide.pdf for important information on
621 upgrading to IBX2.
622
623 1. Size property of TIBStringField is now the width in characters of the field
624 and not the byte length. This applies only to multi-byte character sets such
625 as UTF8. The original approach aligned with TStringField. However, the TStringField
626 code is not recognised as a bug and hence this change to align the behaviour.
627 The TStringField change is expected in fpc 3.2.0.
628
629 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
630 true (default) then Size property value saved in the lfm is ignored. Size is
631 always set from the dynamic information read from the database. It is unclear
632 why anyone would want to override this and set Size to false.
633
634 3. ibxscript: should now handle correctly a Case..End statement within a procedure
635 block.
636
637 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
638 exist when an attempt is made to connect to it (run time only) then an attempt
639 is made to create the database.
640
641 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
642 has been successfully created as a result of a call to CreateDatabase or when
643 creating a database after it was found not to exist.
644
645 6. DBControlGrid: a race condition could result in the wrong row image being
646 written to the cache. This has been avoided by a trip round the message
647 loop before rendering the row image.
648
649 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
650 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
651 known to risk corrupt rendering of row images when the control is first
652 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
653 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
654
655 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
656 a TDateEdit control located on an editor panel.
657
658 9. TIBExtract: brought up-to-date plus many bug fixes.
659
660 10. DBControlGrid: Removed memory leak when updating rows.
661
662 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
663
664 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
665
666 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
667 when target codepage is CP_NONE. This is a workaround for
668 http://bugs.freepascal.org/view.php?id=30622.
669
670 2. DBLog option removed from TIBStatisticalService - not supported by server
671 since Firebird 1.5.
672
673 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
674 similar.
675
676 4. IBCodePage: updated mapping between codepages and character id.
677
678 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
679 Firebird. Character sets with a char width of two are not UTF16.
680
681 6. Strings received from the database are now always transliterated into UTF8
682 regardless of the database character set or connection character set. This
683 is for compatibility with the LCL.
684
685 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
686
687 1. IBBlob: Defer reading of blob until read method called. This avoids having to
688 read in an entire blob just to get the size of the blob. General performance
689 improvement when opening datasets containing blobs.
690
691 2. Clearing a Blob now sets the corresponding field's modified flag.
692
693 3. IBLookupCombo: When not performing auto-complete, original query sort order
694 is now used.
695
696 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
697 determined.
698
699 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
700
701 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
702 lazarus 1.6.0
703
704 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
705 compilation error.
706
707 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
708
709 1. No character set specified for connection: when a text blob is retrieved, the
710 character set is determined by looking up the native character set using then
711 Firebird API. Otherwise a text mode blob is assumed to have the same character
712 set as the connection.
713
714 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
715 for Login Dialog returing a change to the database path.
716
717 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
718 to be changed from that given in the TIBDatabase/TIBServer component and for the
719 entered value to be saved on a project specific basis (design time only).
720
721 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
722 column fieldname. If they are the same then it is acts as a look up for the KeyValue
723 Otherwise, it sets the column text to the selected ListField Value.
724
725 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
726 column width.
727
728 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
729 and a case insensitive search is requested.
730
731 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
732 or column ListSource.
733
734 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
735 unprepare) when closing and the text has not changed.
736
737 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
738 Less likely to cause a cursor re-use error on Windows.
739
740 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
741 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
742
743 11. TIBTreeView: Guard against nil destination on record changed
744
745 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
746 string type with the code page set to reflect the returned field encoding after
747 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
748 earlier versions.
749
750 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
751 will now result in transliteration to the code page specified for the Firebird driver
752 if the assigned string has a different code page. FPC 3.0.0 onwards only.
753
754 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
755 is ignored and the lc_ctype value, when the database is opened, is set to align with
756 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
757 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
758 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
759 the GETACP is used to determine the Windows code page.
760
761 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
762 name used as the lc_ctype when the database was opened. Only valid while the
763 Database is connected.
764
765 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
766 id that corresponds to the DefaultCharSetName.
767
768 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
769
770 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
771 path is given and database attach fails due to access permission issues on the
772 temp directory or security database, then the attach is retried with "localhost:"
773 prefixing the databasename. This should avoid problems when the database has to
774 be accessed by a local (e.g. classic) server and libfbembed is used.
775
776 2. Windows: revised search order for Firebird DLL:
777 i. The Firebird Embedded Server in the application Directory.
778 ii. If the FIREBIRD environment variable is set then the directory this
779 points to is searched for the FB Client DLL and then then underlying
780 "bin" directory.
781 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
782 is used to locate the Firebird installation directory and the underlying
783 "bin" directory is searched for the FB Client DLL.
784 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
785 are searched for the FB Client DLL.
786 v. The PATH Environment variable is used to search for the FB Client DLL.
787 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
788
789 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
790 See doc/readme.scriptengine and example applications.
791
792 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
793 simplify the use of the embedded firebird server on both Linux and Windows platforms.
794 See dpc/readme.localdatabase and example applications.
795
796 5. IBDynamicGrid: Reordering on column header click should now also work for
797 dynamic columns.
798
799 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
800 between incrementing/decrementing the lock count and signalling the event.
801
802 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
803
804 1.3.2 was never formally released and only made available as beta copies.
805
806 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
807
808 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
809
810 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
811
812 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
813 i.e. when it is a calculated field
814
815 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
816 This problem was due to a race condition between recalculating row heights and
817 determining which row was selected by the mouse click. The row height calculation
818 is now deferred by an extra trip round the message loop allowing the row to
819 be always calculated on the current grid layout rather than risking it being
820 calculated on the grid layout after the expanded row has been shrunk.
821
822 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
823 Windows.
824
825 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
826 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
827 to be determined at runtime. See doc/readme.charactersets.html.
828
829 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
830 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
831
832 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
833 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
834 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
835
836 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
837 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
838 implies no truncation.
839
840 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
841
842 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
843 (avoids "Not in Edit Mode" error).
844
845 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
846
847 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
848 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
849
850 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
851
852 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
853
854 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
855
856 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
857
858 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
859
860 1. OnCloseUp Event Handler added to TDBLookupProperties
861
862 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
863 problem with row size when exception is called.
864
865 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
866
867 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
868 in a TCustomComboBox and ignores return key if in a TCustomMemo
869
870 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
871 keyed in i.e. when autocomplete not performed
872
873 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
874 console mode applications with all LCL required functions (builtin dialogs and
875 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
876 not included in your project, IBX should compile and link with a console mode program.
877 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
878 console mode application or the IDE will automatically assume that your
879 application is GUI based. Instead, you should include the ibexpressconsolemode package.
880
881 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
882 to use the built in dialogs and cursor management. IBDialogs is
883 included by default if "ibexpress" is in your project source's "uses" clause.
884 This should be the case for all projects created through the IDE. This is why
885 you do not want to add the ibexpress package to console mode applications. The
886 ibexpressconsolemode package has been created to allow console mode programs
887 to avoid adding LCL dependencies when using IBX, while still having the
888 unit search paths set up correctly.
889
890 Existing users should check to ensure that the "ibexpress" unit is included in
891 each project's source file (*.lpr).
892
893 You may find that in order for the IDE to recognise that ibexpressconsolemode
894 exists, you have to first open the package in the IDE and then close it. This
895 adds it to the most recently accessed packages list. To make it permanently
896 available, add the package name to lazarus' staticpackages.inc file.
897
898 Thanks to Julio Jiménez for suggesting support of console mode.
899
900 7. SQL Parser can now accept quoted strings that include new lines
901
902 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
903 of text on start of edit. This is particularly useful when tabbing to a
904 column and then inserting text.
905
906 9. New Examples provided for IB Services and ISQLMonitor.
907
908 10. Fix error when writing to blob streams that recorded only the last buffer
909 write in the blob stream. In most cases, this did not cause a problem as the
910 IB Blob Stream is written in a single write. However, with the TDBImage, write
911 of a graphic type prefix was lost which caused a problem when the image could
912 not be automatically recognised.
913
914 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
915 already open" errors due to random numbers used for the cursor name being identical.
916
917 12. IBTable: corrected error that could result in an "Index out of bounds" error
918 when opening the table and the Primary Key is the last or only column in the
919 table. Thanks to Rick Hoover for the fix.
920
921 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
922 of "UTF-8", and update list of available database character sets. Existing
923 users should check the current lc_ctype setting in their applications.
924
925 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
926
927 1. Firebird Services: avoid List Index error when opening a service with an
928 empty Params property.
929
930 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
931 Link now set up in Loaded method - avoids occasional failure to apply
932 SQL markup on initial open.
933
934 3. "Employees" example performance improvements when scrolling.
935
936 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
937 TFrame. Force recaching of selected frame to avoid GTK race (results in a
938 random image cached).
939
940 5. DBControlGrid: Should now react to changes in panel height at run time.
941
942 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
943 even when further rows exist.
944
945 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
946 always be derived from panel height and setting this property can cause confusion.
947 Note for existing projects: to avoid a missing property error at run time,
948 each form using the DBControlGrid must be opened, updated and saved in the IDE
949 in order to remove the property value from the lfm.

952 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
953
954 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
955 call Prepare before setting parameter values.
956
957 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
958
959 3. Code tidyup and more robust handling of dsql information result vector.
960
961 4. Support for centralised handling of transaction status changes. TIBTransaction
962 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
963 and "AfterExecQuery". The first three are called after the same event is called
964 for an IBCustomDataSet descendent using the Transaction. The fourth is called
965 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
966 enable monitoring of transaction status changes for a given transaction to be
967 handled in a single place. For example, when a change to the dataset occurs
968 an indicator can be set that shows the user that in order to save changes,
969 the transaction should be committed. Rather than doing this per dataset, this
970 can now be done per transaction.
971
972 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
973 the dataset is scrolled. However, any changes to the current row are, by default,
974 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
975 have a new property "DataSetCloseAction" that adds automatic posting of changes
976 on dataset close. If this property is set to dcDiscardChanges (default) then the
977 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
978 then IBX will attempt to post any unsaved changes before the dataset is closed
979 (and after the BeforeClose event handler is called). The exception is when the
980 dataset is being closed as a result of a transaction rollback. In this case,
981 no action is taken and any unsaved changes are discarded. This avoids both
982 unnecessary overhead and the risk that a validation error may occur in the Post
983 raising an exception and thereby preventing a rollback.
984
985 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
986 In earlier versions, the Display Width was set to the maximum byte width rather than the character
987 width. Display Widths are now corrected by dividing by the max byte width per character.
988 For UTF8 character sets, the byte width is four and hence the Display Width will be
989 the byte width divided by 4. The byte width of each character set is determined
990 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
991 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
992
993 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
994
995 8. IBLookupComboEditBox: List should now always be restored to full list when the
996 control loses focus. Default Key press default interval reduced to 200ms.
997
998 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
999 when dataset rows are less than visible rows.
1000
1001 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1002 does not exist or DataSet is empty. More responsive on dataset open. New event
1003 OnRestorePosition. Column sort disabled if no header row.
1004
1005 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1006 while dataset state is dsInsert. Avoids posting errors.
1007
1008 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1009 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1010
1011 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1012
1013 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1014 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1015 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1016 always "posts" the current record regardless or whether or not it may be more appropriate
1017 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1018 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1019 as the first action of the "Post" method and allows the handler to convert the Post
1020 into a Cancel if that is the appropriate action on moving to a different row. This is
1021 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1022 raised here, but it may still be more appropriate to validate a post and signal
1023 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1024
1025 15. On Unix derived systems, the Firebird library name can now be given as a colon
1026 separated list. Each library name on the list is tried in turn, in left to right
1027 order with the first found being used as the firebird library. By default, on Linux,
1028 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1029 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1030
1031 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1032 then it will still attempt to access the database via the Firebird Server and will
1033 require a username and password. If only the pathname is given, then the username
1034 and password should be omitted and the unix file permissions are used to grant
1035 access.
1036
1037 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1038
1039 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1040 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1041 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1042 corresponds to a row of the linked DataSource. Any data aware control on the
1043 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1044
1045 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1046 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1047 takes place during database access. This may be useful when there are performance issues with
1048 the change of cursor. Setting the property to false suppresses the change of cursor.
1049
1050 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1051 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1052 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1053 making all changes permanent immediately rather than when the transaction is explicitly
1054 committed.
1055
1056 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1057 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.

1061 Development version only.
1062
1063 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1064
1065 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1066 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1067 "Where" and "Having" clauses to implement user specified filters of arbitrary
1068 complexity.
1069
1070 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1071 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1072 These are:
1073
1074 - TIBLookupComboEditBox
1075 - TIBDynamicGrid
1076 - TIBTreeview
1077
1078 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1079 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1080 to revise the available list and restrict it to items that are prefixed by the
1081 typed text (either case sensitive or case insensitive). Autoinsert allows a
1082 newly typed entry to be added to the list dataset and included in the available
1083 list items.
1084
1085 TIBDynamicGrid is a TDBGrid descendent that provides for:
1086 - automatic resizing of selected columns to fill the available row length
1087 - automatic positioning and sizing of a "totals" control, typically at the
1088 column footer, on a per column basis.
1089 - DataSet resorting on header row click, sorting the dataset by the selected column.
1090 A second click on the same header cell reversed the sort order.
1091 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1092 is automatically expanded and a panel superimposed on it. The panel can have any
1093 number of child controls, typically data aware controls with the same datasource
1094 as the grid allowing for editing of additional fields and more complex editors.
1095 - Reselection of the same row following resorting.
1096 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1097 Its properties are specified on a per column basis and allows for one or more
1098 columns to have their values selected from a list provided by a dataset.
1099 Autocomplete and autoinsert are also available. The existing picklist editor
1100 is unaffected by the extension.
1101
1102 TIBTreeView is a data aware TCustomTreeView.
1103
1104 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1105 zero scale will no longer return an error. An Int64 will be returned instead.
1106
1107 4. TIBTransaction now has events for Before and After Transaction End and a new function
1108 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1109
1110 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1111 repeated multiple times.
1112
1113 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1114 check used to get in the way of using Stored Procedures, and "Update or Insert"
1115 statements.
1116
1117 7. Insert, Modify and Delete property Editors now support Query Generation from
1118 Stored Procedures.
1119
1120 8. Three new examples illustrate the use of the new IB Controls
1121
1122
1123 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1124
1125 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1126 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1127 Gabor Boros for reporting this problem and for testing the improvements).
1128
1129 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1130 See readme.field+param.names in the doc folder.
1131
1132 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1133 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1134
1135 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1136
1137 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1138 actions.
1139
1140 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1141 thanks to Yuriy Kopnin for pointing this out).
1142
1143 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1144
1145 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1146 for both fields and parameter setting.
1147
1148 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1149 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1150
1151 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1152 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1153
1154 11. TIBTable now has a property editor for "MasterFields"
1155
1156 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1157 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1158
1159 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1160 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1161

1163 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1164
1165 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1166
1167 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1168
1169 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1170 it is null. This allows for alternative user defined setting of the generator
1171
1172 Many thanks to Julio Jiménez for this fix
1173
1174 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1175 and suggests that the user may have forgotten to install it.
1176
1177 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1178
1179 1. Conditional compilation used to limit registration of TIntegerField to
1180 Lazarus versions less than 1.1
1181
1182 2. When a database connection is created, character set is now by default set
1183 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1184 1250 to 1254.
1185
1186
1187 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1188
1189 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1190
1191
1192 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1193
1194 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1195 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1196
1197 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1198 package is changed to do this (which it should do).
1199
1200 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1201
1202 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1203
1204 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1205
1206 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1207
1208 4. Property editors should now correctly resize.
1209
1210 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1211 (restored original functionality)
1212
1213 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1214 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
