1 IBX Change Log version (2.3-4 Build 11661) Thu, 11 Apr 2019 09:43:38 +0100
2
3 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
4 not SQL Identifiers are now supported.
5
6 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
7 passed to the Firebird engine for execution.

9 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
10
11
12 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
13 and is used to override the default settings in the client side "firebird.conf" This
14 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
15 Each line of the string list should be a setting in the same format as "firebird.conf".
16 For example "WireCompression = true" in order to request wire compression on the client side.
17
18 Note: explicit settings in the client side "firebird.conf" appear to take precedence
19 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
20 also require a compatible setting in the server side "firebird.conf". For example
21 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
22 compression to be used.
23
24 Whether or not WireCompression or WireCrypt are in use can be checked using the information
25 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
26 ibx/examples/dbinfo for examples of how to display this information.
27
28 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
29 is a "convenience" property. If set the "WireCompression=true" is added to the
30 ConfigOverrides. If unchecked then this setting is removed.
31
32 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
33 not "INT64".
34
35 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
36 These are:
37 property TimestampFormat: string;
38 property DateFormat: string;
39 property TimeFormat: string;
40
41 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
42 DATETIME and TIME. The format strings use the standard FPC date/time format
43 characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
44
45 If any of the above properties are set to an empty string, then the locale default
46 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
47 locale default is extended by appending '.zzz' to include milliseconds.
48
49 TIBCSVDataOut by default sets these properties to the empty string, while the other
50 two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
51
52 5. New published property for TIBCSVDataOut:
53 property QuoteStrings: boolean (default true)
54
55 If false then strings are unquoted, otherwise, the QuoteChar property value is
56 used to delimit each and every string in the output.
57
58 6. New published properties for TIBCSVDataOut:
59 property FieldSeparator: string;
60 property HeaderSeparator: string;
61
62 Respectively, these provide the separator character(s) used to separate fields
63 in data and header rows. Both default to ','.
64
65 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
66 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
67 property OnFormatTextString;
68
69 This event handler can be used to process text strings before they are included
70 in the output e.g. to replace unprintable characters with alternative strings.
71 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
72
73 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
74 Uses "FindParam" if in order to find out if a parameter with a given name exists
75 and without raising and exception if it does not.
76
77 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
78 consistency with SQL queries.
79
80 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
81 When true, SQL statement parameter names are parsed case sensitive. Note for
82 TIBDataSet only applies to Select query.
83
84 11. IBEvents: removing a TIBEvent component from a form should no longer result in
85 an IDE exception.
86
87 12. LocalDBSupport: initial database creation should now work correctly
88 when the schema source is an sql file.
89
90 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
91 when defined, this handler will be called by the internal TIBXScript during
92 initial database creation when the schema source is an sql file and may be used
93 to provide a visual indication of progress in console mode.
94
95 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
96 to true while a new local database is being created and its schema populated.
97 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
98 when the database is disconnected/connected during the create DB procedure.
99
100 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
101 are now always ignored and replaced by the user name and password provided as
102 the login parameters for the TIBDatabase referenced from the TIBXScript. The
103 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
104 completely ignored if this property is true.
105
106 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
107 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
108 ImageIndex and SelectImageIndex values on AddNode.
109
110 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
111 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
112 the same database connection.
113
114 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
115 if provided, this should be an conditional SQL expression suitable for
116 including in an SQL Select statement "where" clause. If non-empty and the
117 "Filtered" property is true then the SQL expression provided as the value of
118 the "Filter" property is "ANDed" with any existing condition statement
119 in the SQL statement's "Where" clause.
120
121 If the "Filter" property is set at run time, the "Filtered" property is true
122 and the dataset is already open, then the dataset is closed and re-opened automatically.
123
124 The "Filter" condition may include IBX style parameters. In which case, their
125 value must be set by the dataset's "OnBeforeOpen" event handler.
126
127 This is a public property for TIBDataSet and TIBQuery query and intended for
128 use at run time.
129
130 Note: The property is a published property of TIBTable. The TIBTable functionality
131 is unaffected by this change.
132
133 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
134
135 1. Remove need to check for IsMultiThread by providing access to GUI timers via
136 IBGUIInterface. Note: master/detail delay timer does not apply to console
137 mode apps.
138
139 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
140 statement. This avoids problems if "Execute Block" is used as the Query.
141
142 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
143 internal SQL tokeniser routines.
144
145 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
146 as a select statement, with or without CTEs.
147
148 5. IBSQLParser: parser now recognises the "ROWS" clause.
149
150 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
151 internal SQL tokeniser routines.
152
153 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
154 being raised for valid set statements processed by a data formatter.
155
156 8. New published property for TIBDatabase and TIBXServicesConnection. This is
157 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
158 the path of the Firebird Library used by the database/services connection.
159
160 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
161 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
162 services connection.
163
164 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
165 or param name is not a valid SQL identifier.
166
167 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
168 view of whether the text box should be editable when no DataSource is specified.
169 TIBLookupComboEditBox has been updated to workaround this problem. As long as
170 ReadOnly is false, the text box is editable when no DataSource is specified.
171
172 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
173 the FBLIB environment variable. If you do not want to permit this then you
174 must modify the Register procedure in the design/IBDBReg.pas unit to remove
175 this setting.
176
177 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
178
179 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
180 Utf8EscapeControlChars
181
182 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
183
184 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
185 all previous copies of the IBX source code tree before installing this release.
186
187 The IBX packages used by most users have not changed, with one exception. The
188 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
189 to use the IBServices unit in your applications, please add the iblegacyServices
190 to the list of dependencies. To do this, open the Project Inspector and select
191 Add->New Requirement and select "ibLegacyServices" from the list of available
192 packages.
193
194 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
195 the IBServices unit providing what is intended to be a clearer and easier to
196 use set of IB Services components. See Chapter 10 of the IBX User Guide for
197 more information and the guide to "Firebird Service Management Using IBX".
198 As indicated above, the legacy services components are still available and
199 provided in a separate package. There is no need to update working applications
200 using the older versions except for an additional package dependency.
201
202 2. The IBX packages and source code tree have been re-organised in an attempt to
203 finally get rid of the "duplicate ppu" warnings. This re-organisation should
204 not affect existing users. Section 2.3 of the IBX User Guide describes the
205 new set of IBX packages.
206
207 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
208 updated to use the new Services API components.
209
210 4. The iblocal package has been updated to use the new Services API components.
211
212 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
213 TIBXSecurityService. It had been wrongly classified in the previous version
214 as a per database configuration item. It is global to a server and hence
215 correctly positioned as part of the Security Package. In the DBAdmin example,
216 the setting has moved to the mappings page.
217
218 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
219 are ignored.
220
221 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
222 closed before the database is dropped. Before and After Disconnect event handlers
223 are also fired.
224
225 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
226 is started and not just the first time.
227
228 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
229 depenendency with comp type.
230
231 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
232
233 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
234 then this is recognised and not ignored.
235
236 12. TIBDataSet, TIBQuery, TIBTable: additions:
237 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
238 function GetPerfStatistics(var stats: TPerfCounters): boolean;
239 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
240
241 GetRowsAffected returns the affected row counts from the last insert/update/delete
242 if EnableStatistics = true then GetPerfStatistics returns the current stats
243 counters for the select query. Note: stats accumulate after each fetch from
244 the database. To get total query cost after open, call the "Last" method
245 and then GetPerfStatistics.
246
247 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
248
249 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
250 in parenthesises.
251
252 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
253 SQL identifiers are always delimited by double quotes. If false, then they are
254 only delimited if the identifier is a reserved word, contains lower case or special
255 characters. Set this property to true to retain previous behaviour.
256
257 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
258 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
259
260 16. TIBDataSet, TIBQuery, TIBTable: addition:
261 property MasterDetailDelay: integer {defaults to zero}
262
263 When non-zero and the dataset is a detail table referencing a master table
264 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
265 then a synchronisation delay is added (in milliseconds) between the master
266 row changing and the detail dataset being re-opened. If the master dataset
267 is scrolled before the delay expires then the delay is reset. This can be used
268 to avoid performance overheads when scrolling through a large master dataset.
269
270 Note: uses fptimer and hence requires a thread manager. Under Linux the
271 chreads unit must be included in your project. TTimer is not used in order
272 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
273
274 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
275 with Extract Option eoDatabase.
276
277 18. TIBLookupComboEditBox: Workaround added for https://bugs.freepascal.org/view.php?id=33428
278 When a deLayoutChanged event is reported on the ListSource dataset, the
279 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
280 relationship with the control's datasource (master).
281
282 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
283
284 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
285 stubs. Pedantic fix really, as procedures output in dependency order anyway.
286
287 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
288 DDL (Firebird 3 and later only).
289
290 22. TIBLookupComboBox Autocomplete Fixes:
291 i. Only appended text is now selected after autocomplete.
292 ii. Uppercase keys no longer ignored for autocomplete.
293 iii. Retain Prefix case is now honoured correctly.
294 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
295 before autocomplete performed. i.e. behaviour now the same as when
296 no DataSource assigned.
297
298 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
299 between SQL statements.
300
301 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
302 ObjectNames are converted to upper case before matching against metadata object
303 names, unless the objectname is delimited by double quotes, in which case, the
304 double quotes are removed and the remaining string is used (unmodified) to match
305 against the metadata object name.
306
307 If true then the ObjectName is used as is without modification and matched
308 against the metadata object name. No attempt is made to remove double quotes.
309
310 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
311 with eoTrigger, these extract types can be used to select only Database Triggers,
312 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
313
314 26. TIBXScript: If an exception occurs during the processing of a statement, the
315 statement separate character is now reset to the default (';').
316
317 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
318
319 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
320 a commit or reconnect statement and instead activated only when next SQL statement
321 is executed.
322
323 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
324
325 30. TIBXScript: case insensitive regex now used when matching statements instead of
326 converting statement to upper case.
327
328 31. TIBExtract: metadata comments now supported. New published property
329 IncludeMetaDataComments (default true). If true then metadata comments included
330 in extracted DDL. New Extract Object member eoComments. This may be used with
331 ExtractObject method to list all metadata comments.
332
333 32. TIBExtract: ListObjectNames method added.
334
335 33. Updated Database component editor to support additional connection string
336 types.
337
338 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
339
340 NOTE: THE LOCATIONS OF SOME OF THE UNIT DIRECTORIES HAS CHANGED FROM IBX 2.1. THIS IS TO
341 AVOID DUPLICATE PPU WARNINGS. PLEASE REMOVE EARLIER VERSIONS OF IBX BEFORE INSTALLING THIS
342 RELEASE.
343
344 NOTE: THE DBADMIN DEMO REQUIRES THAT THE MemDSLaz PACKAGE IS INSTALLED IN THE LAZARUS IDE.
345
346 1. IBExtract: Identity columns - add additional check for null column for generator name.
347
348 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
349 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
350 information). However, this is also a very useful mechanism for returning updated computed by
351 column values. Values returned as a result of executing an Insert or Update statement
352 replace existing values in the current row for each corresponding column.
353
354 Previously, if a dataset's select query included read only (computed by) fields then
355 an automatic row refresh was performed after an insert or update query had been processed,
356 irrespective of the setting of the "ForcedUpdates" property. This has changed such
357 that an automatic refresh is no longer performed if an insert or update query contains
358 a returning clause that updates one or more fields on the current row. A full row
359 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
360 field values and the select query contains read only fields. Use of Insert/update
361 returning should be significantly more efficient than executing a refresh query.
362
363 This behaviour change is intended to be backwards compatible and there should be no need to change
364 existing programs, other than to improve performance by using the new capability.
365
366 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
367 they are called when the dataset row is being deleted, there is no value in
368 updating the current record from the query result. Instead, a new event handler
369 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
370 an OnDeleteReturning event handler is provided then it is called with the IResults returned
371 by the query. The event handler can then interrogate the query results and
372 perform whatever action is necessary. For example to confirm, to the user,
373 the deletion of a row with the returned values.
374
375 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
376 any Computed By or Identity Columns. The IBTables example has been updated to
377 illustrate the computation of the employee Full Name on update.
378
379 5. TIBTable: The GeneratorField property is now published.
380
381 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
382 When InsertSQL is generated, the Identity columns are not included in the list of values to
383 be inserted. A RETURNING clause is added to the insert statement to return the value of
384 each Identity column after the insert is executed.
385
386 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
387 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
388 Insert..Returning clause.
389
390 8. TIBGenerator: small performance improvement by not preparing query each time
391 a new value is generated.
392
393 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
394
395 10. Property editors will now sync table name to a System Table when "Include System
396 Tables" is selected and the query is for a System Table.
397
398 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
399 values are no longer converted to milliseconds from TDateTime and then back again
400 to TDateTime (the conversion to milliseconds is the default TDataset approach).
401
402 12. Property Editors handling of Stored Procedures.
403 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
404 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
405 query).
406 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
407
408 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
409 can be used to select a package. If non-empty, the stored procedure name is
410 expected to be a stored procedure defined in the specified package and the
411 generated SQL will be as required for a stored procedure located in a package.
412
413 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
414 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
415 which a stored procedure can be selected. With no package name selected, non-package
416 stored procedures are listed.
417
418 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
419 for password on reconnect.
420
421 16. TIBDatabase: use IAttachment for connection default character set id, code page
422 and character set name.
423
424 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
425 DB info lookups"
426
427 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
428
429 19. Add a property Editor for TIBUpdate.RefreshSQL.
430
431 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
432 parameters. This stops an exception being raised when the field cannot be
433 located in the record buffer.
434
435 21. Property Editors now automatically include System Tables when opened and when the query table
436 is a System Table.
437
438 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
439 This avoids errors due to a stale SQRB or SRB being used for the next query.
440
441 23. IBServices: Service attach parameters now include "expected_db". This is used to
442 add the SPB item isc_spb_expected_db. This names a database using
443 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
444 database. examples/services re-written to illustrate use of "expected_db".
445
446 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
447 This avoids truncated backups when the server returns a timeout (busy) response.
448
449 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
450
451 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
452 databasenames. These are respectively expanded to the local system's temp directory
453 (including trailing delimiter) or to a prescribed data directory (including
454 trailing delimiter). Under Unix systems the data directory is a hidden directory
455 in the user's home directory. The hidden directory name is either the string returned
456 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
457 Under Windows, the directory is the same as the Data Directory as decribed
458 above but instead prefixed by the User's application data path. These may be
459 used to improve application portability for Personal Databases.
460
461 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
462 this has not worked for a long time and is not useful either. FieldDefs should be
463 managed using the Fields Editor as with any other dataset. To access the fields
464 editor for a TIBTable component, double click on the component. The fields editor
465 is then displayed.
466
467 28. TIBDatabaseInfo: new properties/function
468 * DateDBCreated (returns date/time database created)
469 * TransactionCount (returns no. of active transactions)
470 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
471 * PagesFree (Firebird 3 or later)
472 * PagesUsed (Firebird 3 or later)
473 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
474 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
475
476 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
477
478 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
479
480 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
481 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
482
483 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
484 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
485 firing during backup and restore.
486
487 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
488 for verbose output using the new property "StatisticsRequested".
489 see https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-util-gbak.html#rnfb25-util-gbakstats
490
491 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
492
493 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
494 palette. This uses the online validation feature added in Firebird 2.5. The
495 services's properties enable inclusion/exclusion of tables and indexes using
496 regular expressions. See.
497 https://firebirdsql.org/file/documentation/release_notes/html/en/2_5/rnfb25-apiods-api.html#rnfb25-apiods-api-onlinevalidation
498
499 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
500 option on a database.
501
502 37. TIBCustomService: Assign method implemented to allow copying of service login
503 context between service API components. "Detach" method now only detaches
504 service when last reference to the service interface detaches. Tidy up of
505 code for SetActive and Attach methods including password hiding.
506
507 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
508 and used to determine the auth method and protocol used for the connection.
509
510 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
511 a Create Database Statement generated by IBX.
512
513 40. All IBServices now have an additional published property "PortNo". This may
514 be set to a non-standard port number when necessary. If zero then the default
515 port number is used.
516
517 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
518 and not just the mouse.
519
520 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
521
522 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
523 image index and selected image index for each node to be set from a database field.
524
525 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
526 then database schema includes grants to all users. If not present then the
527 only user grants included are those to User PUBLIC.
528
529 45. TIBTreeView: performance improvement. When expanding include both expanded node
530 and child nodes in dataset.
531
532
533 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
534
535 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
536 changes.
537
538 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
539 Bug could result in truncated multi-byte character set values.
540
541 3. Changes consequential on moving fbintf character set utility functions from
542 IFirebirdAPI to IAttachment.
543
544 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
545
546 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
547 results in autocomplete ignoring prefix text.
548
549 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
550 entering a new name into the text box.
551
552 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
553 Firebird rather than recomputing it.
554
555 8. Property Editor positioning tidy up: All IBX Property editors should now be
556 screen centre. Previously some were "poDesigned" which may be inappropriate
557 for multi monitor desktops.
558
559 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
560
561 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
562 a transaction and always reset the object.
563
564 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
565
566 13. TIBXScript: Allow for override of database filename in Create Database statements.
567
568 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
569 to a gbak format archive.
570
571 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
572
573 16. IBLocaldb: Drop database if error creating an empty database.
574
575 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
576 unless selected node not in current dataset.
577
578 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
579 to TIBCustomService, and IBlocalDB code tidy up.
580
581 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
582 behaviour due to uninitialised variable.
583
584 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
585 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
586
587 21. IBSQL: When Database changed ensure that all resources are freed.
588
589 22. IBCustomDataset: When database changed ensure that queries an unprepared.
590
591 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
592 * Line Wrap on SQL Token boundaries (on user command)
593 * auto-complete table names in drop down list of table names
594 * Double click on tablename or field name adds to SQL text
595
596 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
597
598 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
599 TVariantArray. Seems to avoid memory corruption in Windows (probably a
600 workaround for a problem in fpc 3.0.4 win64).
601
602 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
603
604 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
605
606 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
607
608 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
609 include remote system name.
610
611 2. TIBExtract: No longer include comment header and COMMIT statement for empty
612 tables when data included in output.
613
614 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
615 and timing information to be written to stdout. This may be used to locate
616 performance bottlenecks.
617
618 4. SQLParser: only call "OnChanging" event handler when value is different.
619
620 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
621
622 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
623 that BindFields is called when the query is next activated. Avoids FieldName
624 not found error.
625
626 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
627 purpose and allows the programmer to define any action they want for Update, Insert
628 or Delete. This may be complex SQL (similar to a Trigger), application specific
629 filtering of updates, or use of statements such as Grant or Revoke instead of
630 normal DML. See User Manual for more information.
631
632 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
633
634 1. TIBEvents: Fix uninitialised variable that could result in lost events.
635
636 2. TIBExtract: Added support for FB3 "USAGE" privilege.
637
638 3. TIBExtract: data formatted as Charset set "octets" is now output using
639 hexadecimal notation.
640
641 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
642 using a simple XML format.
643
644 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
645 grants to these objects.
646
647 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
648 dependency problems restoring complex databases.
649
650 7. TIBXScript: This component has been restructured to allow for the processing of
651 embedded XML in INSERT statements and to support interactive sources in addition
652 to non-interactive data sources such as files.
653
654 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
655
656 9. TIBXScript: ISQL compatiable Set statements are now supported:
657 SET SQL DIALECT
658 SET TERM
659 SET AUTODDL
660 SET BAIL
661 SET ECHO
662 SET COUNT
663 SET STATS
664 SET NAMES <character set>
665
666 10. IBVersion unit added to hold current IBX Version Number information.
667
668 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
669 and domain definitions.
670
671 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
672 fully supported.
673
674 13. TIBExtract: when a database dump includes data, the generator values are now also set.
675
676 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
677
678 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
679
680 See also doc/IBX4LazarusGuide.pdf for important information on
681 upgrading to IBX2.
682
683 1. Size property of TIBStringField is now the width in characters of the field
684 and not the byte length. This applies only to multi-byte character sets such
685 as UTF8. The original approach aligned with TStringField. However, the TStringField
686 code is not recognised as a bug and hence this change to align the behaviour.
687 The TStringField change is expected in fpc 3.2.0.
688
689 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
690 true (default) then Size property value saved in the lfm is ignored. Size is
691 always set from the dynamic information read from the database. It is unclear
692 why anyone would want to override this and set Size to false.
693
694 3. ibxscript: should now handle correctly a Case..End statement within a procedure
695 block.
696
697 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
698 exist when an attempt is made to connect to it (run time only) then an attempt
699 is made to create the database.
700
701 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
702 has been successfully created as a result of a call to CreateDatabase or when
703 creating a database after it was found not to exist.
704
705 6. DBControlGrid: a race condition could result in the wrong row image being
706 written to the cache. This has been avoided by a trip round the message
707 loop before rendering the row image.
708
709 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
710 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
711 known to risk corrupt rendering of row images when the control is first
712 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
713 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
714
715 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
716 a TDateEdit control located on an editor panel.
717
718 9. TIBExtract: brought up-to-date plus many bug fixes.
719
720 10. DBControlGrid: Removed memory leak when updating rows.
721
722 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
723
724 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
725
726 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
727 when target codepage is CP_NONE. This is a workaround for
728 http://bugs.freepascal.org/view.php?id=30622.
729
730 2. DBLog option removed from TIBStatisticalService - not supported by server
731 since Firebird 1.5.
732
733 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
734 similar.
735
736 4. IBCodePage: updated mapping between codepages and character id.
737
738 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
739 Firebird. Character sets with a char width of two are not UTF16.
740
741 6. Strings received from the database are now always transliterated into UTF8
742 regardless of the database character set or connection character set. This
743 is for compatibility with the LCL.
744
745 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
746
747 1. IBBlob: Defer reading of blob until read method called. This avoids having to
748 read in an entire blob just to get the size of the blob. General performance
749 improvement when opening datasets containing blobs.
750
751 2. Clearing a Blob now sets the corresponding field's modified flag.
752
753 3. IBLookupCombo: When not performing auto-complete, original query sort order
754 is now used.
755
756 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
757 determined.
758
759 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
760
761 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
762 lazarus 1.6.0
763
764 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
765 compilation error.
766
767 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
768
769 1. No character set specified for connection: when a text blob is retrieved, the
770 character set is determined by looking up the native character set using then
771 Firebird API. Otherwise a text mode blob is assumed to have the same character
772 set as the connection.
773
774 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
775 for Login Dialog returing a change to the database path.
776
777 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
778 to be changed from that given in the TIBDatabase/TIBServer component and for the
779 entered value to be saved on a project specific basis (design time only).
780
781 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
782 column fieldname. If they are the same then it is acts as a look up for the KeyValue
783 Otherwise, it sets the column text to the selected ListField Value.
784
785 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
786 column width.
787
788 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
789 and a case insensitive search is requested.
790
791 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
792 or column ListSource.
793
794 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
795 unprepare) when closing and the text has not changed.
796
797 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
798 Less likely to cause a cursor re-use error on Windows.
799
800 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
801 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
802
803 11. TIBTreeView: Guard against nil destination on record changed
804
805 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
806 string type with the code page set to reflect the returned field encoding after
807 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
808 earlier versions.
809
810 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
811 will now result in transliteration to the code page specified for the Firebird driver
812 if the assigned string has a different code page. FPC 3.0.0 onwards only.
813
814 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
815 is ignored and the lc_ctype value, when the database is opened, is set to align with
816 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
817 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
818 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
819 the GETACP is used to determine the Windows code page.
820
821 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
822 name used as the lc_ctype when the database was opened. Only valid while the
823 Database is connected.
824
825 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
826 id that corresponds to the DefaultCharSetName.
827
828 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
829
830 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
831 path is given and database attach fails due to access permission issues on the
832 temp directory or security database, then the attach is retried with "localhost:"
833 prefixing the databasename. This should avoid problems when the database has to
834 be accessed by a local (e.g. classic) server and libfbembed is used.
835
836 2. Windows: revised search order for Firebird DLL:
837 i. The Firebird Embedded Server in the application Directory.
838 ii. If the FIREBIRD environment variable is set then the directory this
839 points to is searched for the FB Client DLL and then then underlying
840 "bin" directory.
841 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
842 is used to locate the Firebird installation directory and the underlying
843 "bin" directory is searched for the FB Client DLL.
844 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
845 are searched for the FB Client DLL.
846 v. The PATH Environment variable is used to search for the FB Client DLL.
847 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
848
849 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
850 See doc/readme.scriptengine and example applications.
851
852 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
853 simplify the use of the embedded firebird server on both Linux and Windows platforms.
854 See dpc/readme.localdatabase and example applications.
855
856 5. IBDynamicGrid: Reordering on column header click should now also work for
857 dynamic columns.
858
859 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
860 between incrementing/decrementing the lock count and signalling the event.
861
862 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
863
864 1.3.2 was never formally released and only made available as beta copies.
865
866 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
867
868 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
869
870 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
871
872 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
873 i.e. when it is a calculated field
874
875 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
876 This problem was due to a race condition between recalculating row heights and
877 determining which row was selected by the mouse click. The row height calculation
878 is now deferred by an extra trip round the message loop allowing the row to
879 be always calculated on the current grid layout rather than risking it being
880 calculated on the grid layout after the expanded row has been shrunk.
881
882 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
883 Windows.
884
885 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
886 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
887 to be determined at runtime. See doc/readme.charactersets.html.
888
889 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
890 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
891
892 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
893 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
894 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
895
896 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
897 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
898 implies no truncation.
899
900 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
901
902 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
903 (avoids "Not in Edit Mode" error).
904
905 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
906
907 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
908 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
909
910 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
911
912 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
913
914 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
915
916 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
917
918 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
919
920 1. OnCloseUp Event Handler added to TDBLookupProperties
921
922 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
923 problem with row size when exception is called.
924
925 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
926
927 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
928 in a TCustomComboBox and ignores return key if in a TCustomMemo
929
930 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
931 keyed in i.e. when autocomplete not performed
932
933 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
934 console mode applications with all LCL required functions (builtin dialogs and
935 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
936 not included in your project, IBX should compile and link with a console mode program.
937 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
938 console mode application or the IDE will automatically assume that your
939 application is GUI based. Instead, you should include the ibexpressconsolemode package.
940
941 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
942 to use the built in dialogs and cursor management. IBDialogs is
943 included by default if "ibexpress" is in your project source's "uses" clause.
944 This should be the case for all projects created through the IDE. This is why
945 you do not want to add the ibexpress package to console mode applications. The
946 ibexpressconsolemode package has been created to allow console mode programs
947 to avoid adding LCL dependencies when using IBX, while still having the
948 unit search paths set up correctly.
949
950 Existing users should check to ensure that the "ibexpress" unit is included in
951 each project's source file (*.lpr).
952
953 You may find that in order for the IDE to recognise that ibexpressconsolemode
954 exists, you have to first open the package in the IDE and then close it. This
955 adds it to the most recently accessed packages list. To make it permanently
956 available, add the package name to lazarus' staticpackages.inc file.
957
958 Thanks to Julio Jiménez for suggesting support of console mode.
959
960 7. SQL Parser can now accept quoted strings that include new lines
961
962 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
963 of text on start of edit. This is particularly useful when tabbing to a
964 column and then inserting text.
965
966 9. New Examples provided for IB Services and ISQLMonitor.
967
968 10. Fix error when writing to blob streams that recorded only the last buffer
969 write in the blob stream. In most cases, this did not cause a problem as the
970 IB Blob Stream is written in a single write. However, with the TDBImage, write
971 of a graphic type prefix was lost which caused a problem when the image could
972 not be automatically recognised.
973
974 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
975 already open" errors due to random numbers used for the cursor name being identical.
976
977 12. IBTable: corrected error that could result in an "Index out of bounds" error
978 when opening the table and the Primary Key is the last or only column in the
979 table. Thanks to Rick Hoover for the fix.
980
981 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
982 of "UTF-8", and update list of available database character sets. Existing
983 users should check the current lc_ctype setting in their applications.
984
985 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
986
987 1. Firebird Services: avoid List Index error when opening a service with an
988 empty Params property.
989
990 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
991 Link now set up in Loaded method - avoids occasional failure to apply
992 SQL markup on initial open.
993
994 3. "Employees" example performance improvements when scrolling.
995
996 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
997 TFrame. Force recaching of selected frame to avoid GTK race (results in a
998 random image cached).
999
1000 5. DBControlGrid: Should now react to changes in panel height at run time.
1001
1002 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1003 even when further rows exist.
1004
1005 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1006 always be derived from panel height and setting this property can cause confusion.
1007 Note for existing projects: to avoid a missing property error at run time,
1008 each form using the DBControlGrid must be opened, updated and saved in the IDE
1009 in order to remove the property value from the lfm.
1010
1011
1012 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1013
1014 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1015 call Prepare before setting parameter values.
1016
1017 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1018
1019 3. Code tidyup and more robust handling of dsql information result vector.
1020
1021 4. Support for centralised handling of transaction status changes. TIBTransaction
1022 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1023 and "AfterExecQuery". The first three are called after the same event is called
1024 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1025 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1026 enable monitoring of transaction status changes for a given transaction to be
1027 handled in a single place. For example, when a change to the dataset occurs
1028 an indicator can be set that shows the user that in order to save changes,
1029 the transaction should be committed. Rather than doing this per dataset, this
1030 can now be done per transaction.
1031
1032 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1033 the dataset is scrolled. However, any changes to the current row are, by default,
1034 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1035 have a new property "DataSetCloseAction" that adds automatic posting of changes
1036 on dataset close. If this property is set to dcDiscardChanges (default) then the
1037 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1038 then IBX will attempt to post any unsaved changes before the dataset is closed
1039 (and after the BeforeClose event handler is called). The exception is when the
1040 dataset is being closed as a result of a transaction rollback. In this case,
1041 no action is taken and any unsaved changes are discarded. This avoids both
1042 unnecessary overhead and the risk that a validation error may occur in the Post
1043 raising an exception and thereby preventing a rollback.
1044
1045 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1046 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1047 width. Display Widths are now corrected by dividing by the max byte width per character.
1048 For UTF8 character sets, the byte width is four and hence the Display Width will be
1049 the byte width divided by 4. The byte width of each character set is determined
1050 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1051 system table. (see also http://bugs.freepascal.org/view.php?id=27766).
1052
1053 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1054
1055 8. IBLookupComboEditBox: List should now always be restored to full list when the
1056 control loses focus. Default Key press default interval reduced to 200ms.
1057
1058 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1059 when dataset rows are less than visible rows.
1060
1061 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1062 does not exist or DataSet is empty. More responsive on dataset open. New event
1063 OnRestorePosition. Column sort disabled if no header row.
1064
1065 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1066 while dataset state is dsInsert. Avoids posting errors.
1067
1068 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1069 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1070
1071 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1072
1073 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1074 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1075 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1076 always "posts" the current record regardless or whether or not it may be more appropriate
1077 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1078 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1079 as the first action of the "Post" method and allows the handler to convert the Post
1080 into a Cancel if that is the appropriate action on moving to a different row. This is
1081 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1082 raised here, but it may still be more appropriate to validate a post and signal
1083 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1084
1085 15. On Unix derived systems, the Firebird library name can now be given as a colon
1086 separated list. Each library name on the list is tried in turn, in left to right
1087 order with the first found being used as the firebird library. By default, on Linux,
1088 the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be
1089 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1090
1091 Note: when using the libfbembed.so, if you prefix the database name with "localhost:"
1092 then it will still attempt to access the database via the Firebird Server and will
1093 require a username and password. If only the pathname is given, then the username
1094 and password should be omitted and the unix file permissions are used to grant
1095 access.
1096
1097 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1098
1099 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1100 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1101 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1102 corresponds to a row of the linked DataSource. Any data aware control on the
1103 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1104
1105 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1106 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1107 takes place during database access. This may be useful when there are performance issues with
1108 the change of cursor. Setting the property to false suppresses the change of cursor.
1109
1110 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1111 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1112 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1113 making all changes permanent immediately rather than when the transaction is explicitly
1114 committed.
1115
1116 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1117 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1118
1119 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1120
1121 Development version only.
1122
1123 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1124
1125 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1126 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1127 "Where" and "Having" clauses to implement user specified filters of arbitrary
1128 complexity.
1129
1130 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1131 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1132 These are:
1133
1134 - TIBLookupComboEditBox
1135 - TIBDynamicGrid
1136 - TIBTreeview
1137
1138 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1139 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1140 to revise the available list and restrict it to items that are prefixed by the
1141 typed text (either case sensitive or case insensitive). Autoinsert allows a
1142 newly typed entry to be added to the list dataset and included in the available
1143 list items.
1144
1145 TIBDynamicGrid is a TDBGrid descendent that provides for:
1146 - automatic resizing of selected columns to fill the available row length
1147 - automatic positioning and sizing of a "totals" control, typically at the
1148 column footer, on a per column basis.
1149 - DataSet resorting on header row click, sorting the dataset by the selected column.
1150 A second click on the same header cell reversed the sort order.
1151 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1152 is automatically expanded and a panel superimposed on it. The panel can have any
1153 number of child controls, typically data aware controls with the same datasource
1154 as the grid allowing for editing of additional fields and more complex editors.
1155 - Reselection of the same row following resorting.
1156 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1157 Its properties are specified on a per column basis and allows for one or more
1158 columns to have their values selected from a list provided by a dataset.
1159 Autocomplete and autoinsert are also available. The existing picklist editor
1160 is unaffected by the extension.
1161
1162 TIBTreeView is a data aware TCustomTreeView.
1163
1164 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1165 zero scale will no longer return an error. An Int64 will be returned instead.
1166
1167 4. TIBTransaction now has events for Before and After Transaction End and a new function
1168 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1169
1170 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1171 repeated multiple times.
1172
1173 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1174 check used to get in the way of using Stored Procedures, and "Update or Insert"
1175 statements.
1176
1177 7. Insert, Modify and Delete property Editors now support Query Generation from
1178 Stored Procedures.
1179
1180 8. Three new examples illustrate the use of the new IB Controls
1181
1182
1183 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1184
1185 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1186 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1187 Gabor Boros for reporting this problem and for testing the improvements).
1188
1189 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1190 See readme.field+param.names in the doc folder.
1191
1192 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1193 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1194
1195 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1196
1197 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1198 actions.
1199
1200 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1201 thanks to Yuriy Kopnin for pointing this out).
1202
1203 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1204
1205 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1206 for both fields and parameter setting.
1207
1208 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1209 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1210
1211 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1212 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1213
1214 11. TIBTable now has a property editor for "MasterFields"
1215
1216 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1217 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1218
1219 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1220 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1221

1223 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1224
1225 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1226
1227 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1228
1229 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1230 it is null. This allows for alternative user defined setting of the generator
1231
1232 Many thanks to Julio Jiménez for this fix
1233
1234 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1235 and suggests that the user may have forgotten to install it.
1236
1237 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1238
1239 1. Conditional compilation used to limit registration of TIntegerField to
1240 Lazarus versions less than 1.1
1241
1242 2. When a database connection is created, character set is now by default set
1243 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1244 1250 to 1254.
1245
1246
1247 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1248
1249 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1250
1251
1252 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1253
1254 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1255 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1256
1257 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1258 package is changed to do this (which it should do).
1259
1260 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1261
1262 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1263
1264 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1265
1266 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1267
1268 4. Property editors should now correctly resize.
1269
1270 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1271 (restored original functionality)
1272
1273 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1274 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
