1 IBX Change Log version (2.3-5 Build 12234) Sat, 18 Jul 2020 11:13:30 +0100
3 1. TIBStringField: when a string value is read from a dataset buffer, if the
4 number of UTF8 characters exceeds the string size then string is truncated
5 to the maximum string size. This is usually a problem with fixed width columns
6 right padded with white space.
8 2. SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 If SQLFiltered is set then when a dataset is opened, each line in the
10 SQLFilterParams property is assumed to be a SQL condition clause and
11 ANDed into the Where clause of the SQL Select statement provided as a
12 dataset property. Each such SQL condition thus acts as an additional filter
13 on the dataset. (Not yet tested)
15 3. The Filtered property inherited from TDataset is no longer used for SQL (server
16 side filters).
18 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
20 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
21 not SQL Identifiers are now supported.
23 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
24 passed to the Firebird engine for execution.
26 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
27 is made to scroll back.
29 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
31 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
32 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
34 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
35 validated. If no match is found in the list of field names and the database has
36 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
37 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
39 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
40 with fpc 3.2.
42 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
45 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
46 and is used to override the default settings in the client side "firebird.conf" This
47 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
48 Each line of the string list should be a setting in the same format as "firebird.conf".
49 For example "WireCompression = true" in order to request wire compression on the client side.
51 Note: explicit settings in the client side "firebird.conf" appear to take precedence
52 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
53 also require a compatible setting in the server side "firebird.conf". For example
54 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
55 compression to be used.
57 Whether or not WireCompression or WireCrypt are in use can be checked using the information
58 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
59 ibx/examples/dbinfo for examples of how to display this information.
61 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
62 is a "convenience" property. If set the "WireCompression=true" is added to the
63 ConfigOverrides. If unchecked then this setting is removed.
65 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
66 not "INT64".
68 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
69 These are:
70 property TimestampFormat: string;
71 property DateFormat: string;
72 property TimeFormat: string;
74 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
75 DATETIME and TIME. The format strings use the standard FPC date/time format
76 characters (see
78 If any of the above properties are set to an empty string, then the locale default
79 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
80 locale default is extended by appending '.zzz' to include milliseconds.
82 TIBCSVDataOut by default sets these properties to the empty string, while the other
83 two use: ' hh:nn:ss.zzz', '' and 'hh:nn:ss.zzz' respectively.
85 5. New published property for TIBCSVDataOut:
86 property QuoteStrings: boolean (default true)
88 If false then strings are unquoted, otherwise, the QuoteChar property value is
89 used to delimit each and every string in the output.
91 6. New published properties for TIBCSVDataOut:
92 property FieldSeparator: string;
93 property HeaderSeparator: string;
95 Respectively, these provide the separator character(s) used to separate fields
96 in data and header rows. Both default to ','.
98 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
99 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
100 property OnFormatTextString;
102 This event handler can be used to process text strings before they are included
103 in the output e.g. to replace unprintable characters with alternative strings.
104 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
106 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
107 Uses "FindParam" if in order to find out if a parameter with a given name exists
108 and without raising and exception if it does not.
110 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
111 consistency with SQL queries.
113 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
114 When true, SQL statement parameter names are parsed case sensitive. Note for
115 TIBDataSet only applies to Select query.
117 11. IBEvents: removing a TIBEvent component from a form should no longer result in
118 an IDE exception.
120 12. LocalDBSupport: initial database creation should now work correctly
121 when the schema source is an sql file.
123 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
124 when defined, this handler will be called by the internal TIBXScript during
125 initial database creation when the schema source is an sql file and may be used
126 to provide a visual indication of progress in console mode.
128 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
129 to true while a new local database is being created and its schema populated.
130 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
131 when the database is disconnected/connected during the create DB procedure.
133 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
134 are now always ignored and replaced by the user name and password provided as
135 the login parameters for the TIBDatabase referenced from the TIBXScript. The
136 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
137 completely ignored if this property is true.
139 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
140 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
141 ImageIndex and SelectImageIndex values on AddNode.
143 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
144 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
145 the same database connection.
147 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
148 if provided, this should be an conditional SQL expression suitable for
149 including in an SQL Select statement "where" clause. If non-empty and the
150 "Filtered" property is true then the SQL expression provided as the value of
151 the "Filter" property is "ANDed" with any existing condition statement
152 in the SQL statement's "Where" clause.
154 If the "Filter" property is set at run time, the "Filtered" property is true
155 and the dataset is already open, then the dataset is closed and re-opened automatically.
157 The "Filter" condition may include IBX style parameters. In which case, their
158 value must be set by the dataset's "OnBeforeOpen" event handler.
160 This is a public property for TIBDataSet and TIBQuery query and intended for
161 use at run time.
163 Note: The property is a published property of TIBTable. The TIBTable functionality
164 is unaffected by this change.
166 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
168 1. Remove need to check for IsMultiThread by providing access to GUI timers via
169 IBGUIInterface. Note: master/detail delay timer does not apply to console
170 mode apps.
172 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
173 statement. This avoids problems if "Execute Block" is used as the Query.
175 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
176 internal SQL tokeniser routines.
178 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
179 as a select statement, with or without CTEs.
181 5. IBSQLParser: parser now recognises the "ROWS" clause.
183 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
184 internal SQL tokeniser routines.
186 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
187 being raised for valid set statements processed by a data formatter.
189 8. New published property for TIBDatabase and TIBXServicesConnection. This is
190 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
191 the path of the Firebird Library used by the database/services connection.
193 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
194 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
195 services connection.
197 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
198 or param name is not a valid SQL identifier.
200 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
201 view of whether the text box should be editable when no DataSource is specified.
202 TIBLookupComboEditBox has been updated to workaround this problem. As long as
203 ReadOnly is false, the text box is editable when no DataSource is specified.
205 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
206 the FBLIB environment variable. If you do not want to permit this then you
207 must modify the Register procedure in the design/IBDBReg.pas unit to remove
208 this setting.
210 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
212 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
213 Utf8EscapeControlChars
215 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
217 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
218 all previous copies of the IBX source code tree before installing this release.
220 The IBX packages used by most users have not changed, with one exception. The
221 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
222 to use the IBServices unit in your applications, please add the iblegacyServices
223 to the list of dependencies. To do this, open the Project Inspector and select
224 Add->New Requirement and select "ibLegacyServices" from the list of available
225 packages.
227 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
228 the IBServices unit providing what is intended to be a clearer and easier to
229 use set of IB Services components. See Chapter 10 of the IBX User Guide for
230 more information and the guide to "Firebird Service Management Using IBX".
231 As indicated above, the legacy services components are still available and
232 provided in a separate package. There is no need to update working applications
233 using the older versions except for an additional package dependency.
235 2. The IBX packages and source code tree have been re-organised in an attempt to
236 finally get rid of the "duplicate ppu" warnings. This re-organisation should
237 not affect existing users. Section 2.3 of the IBX User Guide describes the
238 new set of IBX packages.
240 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
241 updated to use the new Services API components.
243 4. The iblocal package has been updated to use the new Services API components.
245 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
246 TIBXSecurityService. It had been wrongly classified in the previous version
247 as a per database configuration item. It is global to a server and hence
248 correctly positioned as part of the Security Package. In the DBAdmin example,
249 the setting has moved to the mappings page.
251 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
252 are ignored.
254 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
255 closed before the database is dropped. Before and After Disconnect event handlers
256 are also fired.
258 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
259 is started and not just the first time.
261 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
262 depenendency with comp type.
264 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
266 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
267 then this is recognised and not ignored.
269 12. TIBDataSet, TIBQuery, TIBTable: additions:
270 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
271 function GetPerfStatistics(var stats: TPerfCounters): boolean;
272 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
274 GetRowsAffected returns the affected row counts from the last insert/update/delete
275 if EnableStatistics = true then GetPerfStatistics returns the current stats
276 counters for the select query. Note: stats accumulate after each fetch from
277 the database. To get total query cost after open, call the "Last" method
278 and then GetPerfStatistics.
280 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
282 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
283 in parenthesises.
285 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
286 SQL identifiers are always delimited by double quotes. If false, then they are
287 only delimited if the identifier is a reserved word, contains lower case or special
288 characters. Set this property to true to retain previous behaviour.
290 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
291 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
293 16. TIBDataSet, TIBQuery, TIBTable: addition:
294 property MasterDetailDelay: integer {defaults to zero}
296 When non-zero and the dataset is a detail table referencing a master table
297 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
298 then a synchronisation delay is added (in milliseconds) between the master
299 row changing and the detail dataset being re-opened. If the master dataset
300 is scrolled before the delay expires then the delay is reset. This can be used
301 to avoid performance overheads when scrolling through a large master dataset.
303 Note: uses fptimer and hence requires a thread manager. Under Linux the
304 chreads unit must be included in your project. TTimer is not used in order
305 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
307 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
308 with Extract Option eoDatabase.
310 18. TIBLookupComboEditBox: Workaround added for
311 When a deLayoutChanged event is reported on the ListSource dataset, the
312 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
313 relationship with the control's datasource (master).
315 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
317 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
318 stubs. Pedantic fix really, as procedures output in dependency order anyway.
320 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
321 DDL (Firebird 3 and later only).
323 22. TIBLookupComboBox Autocomplete Fixes:
324 i. Only appended text is now selected after autocomplete.
325 ii. Uppercase keys no longer ignored for autocomplete.
326 iii. Retain Prefix case is now honoured correctly.
327 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
328 before autocomplete performed. i.e. behaviour now the same as when
329 no DataSource assigned.
331 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
332 between SQL statements.
334 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
335 ObjectNames are converted to upper case before matching against metadata object
336 names, unless the objectname is delimited by double quotes, in which case, the
337 double quotes are removed and the remaining string is used (unmodified) to match
338 against the metadata object name.
340 If true then the ObjectName is used as is without modification and matched
341 against the metadata object name. No attempt is made to remove double quotes.
343 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
344 with eoTrigger, these extract types can be used to select only Database Triggers,
345 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
347 26. TIBXScript: If an exception occurs during the processing of a statement, the
348 statement separate character is now reset to the default (';').
350 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
352 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
353 a commit or reconnect statement and instead activated only when next SQL statement
354 is executed.
356 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
358 30. TIBXScript: case insensitive regex now used when matching statements instead of
359 converting statement to upper case.
361 31. TIBExtract: metadata comments now supported. New published property
362 IncludeMetaDataComments (default true). If true then metadata comments included
363 in extracted DDL. New Extract Object member eoComments. This may be used with
364 ExtractObject method to list all metadata comments.
366 32. TIBExtract: ListObjectNames method added.
368 33. Updated Database component editor to support additional connection string
369 types.
371 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
379 1. IBExtract: Identity columns - add additional check for null column for generator name.
381 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
382 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
383 information). However, this is also a very useful mechanism for returning updated computed by
384 column values. Values returned as a result of executing an Insert or Update statement
385 replace existing values in the current row for each corresponding column.
387 Previously, if a dataset's select query included read only (computed by) fields then
388 an automatic row refresh was performed after an insert or update query had been processed,
389 irrespective of the setting of the "ForcedUpdates" property. This has changed such
390 that an automatic refresh is no longer performed if an insert or update query contains
391 a returning clause that updates one or more fields on the current row. A full row
392 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
393 field values and the select query contains read only fields. Use of Insert/update
394 returning should be significantly more efficient than executing a refresh query.
396 This behaviour change is intended to be backwards compatible and there should be no need to change
397 existing programs, other than to improve performance by using the new capability.
399 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
400 they are called when the dataset row is being deleted, there is no value in
401 updating the current record from the query result. Instead, a new event handler
402 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
403 an OnDeleteReturning event handler is provided then it is called with the IResults returned
404 by the query. The event handler can then interrogate the query results and
405 perform whatever action is necessary. For example to confirm, to the user,
406 the deletion of a row with the returned values.
408 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
409 any Computed By or Identity Columns. The IBTables example has been updated to
410 illustrate the computation of the employee Full Name on update.
412 5. TIBTable: The GeneratorField property is now published.
414 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
415 When InsertSQL is generated, the Identity columns are not included in the list of values to
416 be inserted. A RETURNING clause is added to the insert statement to return the value of
417 each Identity column after the insert is executed.
419 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
420 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
421 Insert..Returning clause.
423 8. TIBGenerator: small performance improvement by not preparing query each time
424 a new value is generated.
426 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
428 10. Property editors will now sync table name to a System Table when "Include System
429 Tables" is selected and the query is for a System Table.
431 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
432 values are no longer converted to milliseconds from TDateTime and then back again
433 to TDateTime (the conversion to milliseconds is the default TDataset approach).
435 12. Property Editors handling of Stored Procedures.
436 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
437 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
438 query).
439 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
441 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
442 can be used to select a package. If non-empty, the stored procedure name is
443 expected to be a stored procedure defined in the specified package and the
444 generated SQL will be as required for a stored procedure located in a package.
446 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
447 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
448 which a stored procedure can be selected. With no package name selected, non-package
449 stored procedures are listed.
451 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
452 for password on reconnect.
454 16. TIBDatabase: use IAttachment for connection default character set id, code page
455 and character set name.
457 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
458 DB info lookups"
460 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
462 19. Add a property Editor for TIBUpdate.RefreshSQL.
464 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
465 parameters. This stops an exception being raised when the field cannot be
466 located in the record buffer.
468 21. Property Editors now automatically include System Tables when opened and when the query table
469 is a System Table.
471 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
472 This avoids errors due to a stale SQRB or SRB being used for the next query.
474 23. IBServices: Service attach parameters now include "expected_db". This is used to
475 add the SPB item isc_spb_expected_db. This names a database using
476 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
477 database. examples/services re-written to illustrate use of "expected_db".
479 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
480 This avoids truncated backups when the server returns a timeout (busy) response.
482 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
484 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
485 databasenames. These are respectively expanded to the local system's temp directory
486 (including trailing delimiter) or to a prescribed data directory (including
487 trailing delimiter). Under Unix systems the data directory is a hidden directory
488 in the user's home directory. The hidden directory name is either the string returned
489 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
490 Under Windows, the directory is the same as the Data Directory as decribed
491 above but instead prefixed by the User's application data path. These may be
492 used to improve application portability for Personal Databases.
494 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
495 this has not worked for a long time and is not useful either. FieldDefs should be
496 managed using the Fields Editor as with any other dataset. To access the fields
497 editor for a TIBTable component, double click on the component. The fields editor
498 is then displayed.
500 28. TIBDatabaseInfo: new properties/function
501 * DateDBCreated (returns date/time database created)
502 * TransactionCount (returns no. of active transactions)
503 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
504 * PagesFree (Firebird 3 or later)
505 * PagesUsed (Firebird 3 or later)
506 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
507 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
509 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
511 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
513 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
514 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
516 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
517 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
518 firing during backup and restore.
520 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
521 for verbose output using the new property "StatisticsRequested".
522 see
524 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
526 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
527 palette. This uses the online validation feature added in Firebird 2.5. The
528 services's properties enable inclusion/exclusion of tables and indexes using
529 regular expressions. See.
532 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
533 option on a database.
535 37. TIBCustomService: Assign method implemented to allow copying of service login
536 context between service API components. "Detach" method now only detaches
537 service when last reference to the service interface detaches. Tidy up of
538 code for SetActive and Attach methods including password hiding.
540 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
541 and used to determine the auth method and protocol used for the connection.
543 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
544 a Create Database Statement generated by IBX.
546 40. All IBServices now have an additional published property "PortNo". This may
547 be set to a non-standard port number when necessary. If zero then the default
548 port number is used.
550 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
551 and not just the mouse.
553 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
555 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
556 image index and selected image index for each node to be set from a database field.
558 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
559 then database schema includes grants to all users. If not present then the
560 only user grants included are those to User PUBLIC.
562 45. TIBTreeView: performance improvement. When expanding include both expanded node
563 and child nodes in dataset.
566 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
568 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
569 changes.
571 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
572 Bug could result in truncated multi-byte character set values.
574 3. Changes consequential on moving fbintf character set utility functions from
575 IFirebirdAPI to IAttachment.
577 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
579 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
580 results in autocomplete ignoring prefix text.
582 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
583 entering a new name into the text box.
585 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
586 Firebird rather than recomputing it.
588 8. Property Editor positioning tidy up: All IBX Property editors should now be
589 screen centre. Previously some were "poDesigned" which may be inappropriate
590 for multi monitor desktops.
592 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
594 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
595 a transaction and always reset the object.
597 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
599 13. TIBXScript: Allow for override of database filename in Create Database statements.
601 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
602 to a gbak format archive.
604 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
606 16. IBLocaldb: Drop database if error creating an empty database.
608 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
609 unless selected node not in current dataset.
611 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
612 to TIBCustomService, and IBlocalDB code tidy up.
614 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
615 behaviour due to uninitialised variable.
617 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
618 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
620 21. IBSQL: When Database changed ensure that all resources are freed.
622 22. IBCustomDataset: When database changed ensure that queries an unprepared.
624 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
625 * Line Wrap on SQL Token boundaries (on user command)
626 * auto-complete table names in drop down list of table names
627 * Double click on tablename or field name adds to SQL text
629 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
631 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
632 TVariantArray. Seems to avoid memory corruption in Windows (probably a
633 workaround for a problem in fpc 3.0.4 win64).
635 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
637 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
639 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
641 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
642 include remote system name.
644 2. TIBExtract: No longer include comment header and COMMIT statement for empty
645 tables when data included in output.
647 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
648 and timing information to be written to stdout. This may be used to locate
649 performance bottlenecks.
651 4. SQLParser: only call "OnChanging" event handler when value is different.
653 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
655 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
656 that BindFields is called when the query is next activated. Avoids FieldName
657 not found error.
659 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
660 purpose and allows the programmer to define any action they want for Update, Insert
661 or Delete. This may be complex SQL (similar to a Trigger), application specific
662 filtering of updates, or use of statements such as Grant or Revoke instead of
663 normal DML. See User Manual for more information.
665 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
667 1. TIBEvents: Fix uninitialised variable that could result in lost events.
669 2. TIBExtract: Added support for FB3 "USAGE" privilege.
671 3. TIBExtract: data formatted as Charset set "octets" is now output using
672 hexadecimal notation.
674 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
675 using a simple XML format.
677 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
678 grants to these objects.
680 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
681 dependency problems restoring complex databases.
683 7. TIBXScript: This component has been restructured to allow for the processing of
684 embedded XML in INSERT statements and to support interactive sources in addition
685 to non-interactive data sources such as files.
687 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
689 9. TIBXScript: ISQL compatiable Set statements are now supported:
697 SET NAMES <character set>
699 10. IBVersion unit added to hold current IBX Version Number information.
701 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
702 and domain definitions.
704 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
705 fully supported.
707 13. TIBExtract: when a database dump includes data, the generator values are now also set.
709 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
711 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
713 See also doc/IBX4LazarusGuide.pdf for important information on
714 upgrading to IBX2.
716 1. Size property of TIBStringField is now the width in characters of the field
717 and not the byte length. This applies only to multi-byte character sets such
718 as UTF8. The original approach aligned with TStringField. However, the TStringField
719 code is not recognised as a bug and hence this change to align the behaviour.
720 The TStringField change is expected in fpc 3.2.0.
722 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
723 true (default) then Size property value saved in the lfm is ignored. Size is
724 always set from the dynamic information read from the database. It is unclear
725 why anyone would want to override this and set Size to false.
727 3. ibxscript: should now handle correctly a Case..End statement within a procedure
728 block.
730 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
731 exist when an attempt is made to connect to it (run time only) then an attempt
732 is made to create the database.
734 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
735 has been successfully created as a result of a call to CreateDatabase or when
736 creating a database after it was found not to exist.
738 6. DBControlGrid: a race condition could result in the wrong row image being
739 written to the cache. This has been avoided by a trip round the message
740 loop before rendering the row image.
742 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
743 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
744 known to risk corrupt rendering of row images when the control is first
745 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
746 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
748 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
749 a TDateEdit control located on an editor panel.
751 9. TIBExtract: brought up-to-date plus many bug fixes.
753 10. DBControlGrid: Removed memory leak when updating rows.
755 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
757 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
759 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
760 when target codepage is CP_NONE. This is a workaround for
763 2. DBLog option removed from TIBStatisticalService - not supported by server
764 since Firebird 1.5.
766 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
767 similar.
769 4. IBCodePage: updated mapping between codepages and character id.
771 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
772 Firebird. Character sets with a char width of two are not UTF16.
774 6. Strings received from the database are now always transliterated into UTF8
775 regardless of the database character set or connection character set. This
776 is for compatibility with the LCL.
778 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
780 1. IBBlob: Defer reading of blob until read method called. This avoids having to
781 read in an entire blob just to get the size of the blob. General performance
782 improvement when opening datasets containing blobs.
784 2. Clearing a Blob now sets the corresponding field's modified flag.
786 3. IBLookupCombo: When not performing auto-complete, original query sort order
787 is now used.
789 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
790 determined.
792 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
794 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
795 lazarus 1.6.0
797 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
798 compilation error.
800 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
802 1. No character set specified for connection: when a text blob is retrieved, the
803 character set is determined by looking up the native character set using then
804 Firebird API. Otherwise a text mode blob is assumed to have the same character
805 set as the connection.
807 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
808 for Login Dialog returing a change to the database path.
810 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
811 to be changed from that given in the TIBDatabase/TIBServer component and for the
812 entered value to be saved on a project specific basis (design time only).
814 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
815 column fieldname. If they are the same then it is acts as a look up for the KeyValue
816 Otherwise, it sets the column text to the selected ListField Value.
818 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
819 column width.
821 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
822 and a case insensitive search is requested.
824 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
825 or column ListSource.
827 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
828 unprepare) when closing and the text has not changed.
830 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
831 Less likely to cause a cursor re-use error on Windows.
833 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
834 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
836 11. TIBTreeView: Guard against nil destination on record changed
838 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
839 string type with the code page set to reflect the returned field encoding after
840 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
841 earlier versions.
843 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
844 will now result in transliteration to the code page specified for the Firebird driver
845 if the assigned string has a different code page. FPC 3.0.0 onwards only.
847 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
848 is ignored and the lc_ctype value, when the database is opened, is set to align with
849 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
850 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
851 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
852 the GETACP is used to determine the Windows code page.
854 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
855 name used as the lc_ctype when the database was opened. Only valid while the
856 Database is connected.
858 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
859 id that corresponds to the DefaultCharSetName.
861 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
863 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
864 path is given and database attach fails due to access permission issues on the
865 temp directory or security database, then the attach is retried with "localhost:"
866 prefixing the databasename. This should avoid problems when the database has to
867 be accessed by a local (e.g. classic) server and libfbembed is used.
869 2. Windows: revised search order for Firebird DLL:
870 i. The Firebird Embedded Server in the application Directory.
871 ii. If the FIREBIRD environment variable is set then the directory this
872 points to is searched for the FB Client DLL and then then underlying
873 "bin" directory.
874 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
875 is used to locate the Firebird installation directory and the underlying
876 "bin" directory is searched for the FB Client DLL.
877 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
878 are searched for the FB Client DLL.
879 v. The PATH Environment variable is used to search for the FB Client DLL.
880 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
882 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
883 See doc/readme.scriptengine and example applications.
885 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
886 simplify the use of the embedded firebird server on both Linux and Windows platforms.
887 See dpc/readme.localdatabase and example applications.
889 5. IBDynamicGrid: Reordering on column header click should now also work for
890 dynamic columns.
892 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
893 between incrementing/decrementing the lock count and signalling the event.
895 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
897 1.3.2 was never formally released and only made available as beta copies.
899 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
901 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
903 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
905 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
906 i.e. when it is a calculated field
908 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
909 This problem was due to a race condition between recalculating row heights and
910 determining which row was selected by the mouse click. The row height calculation
911 is now deferred by an extra trip round the message loop allowing the row to
912 be always calculated on the current grid layout rather than risking it being
913 calculated on the grid layout after the expanded row has been shrunk.
915 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
916 Windows.
918 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
919 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
920 to be determined at runtime. See doc/readme.charactersets.html.
922 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
923 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
925 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
926 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
927 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
929 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
930 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
931 implies no truncation.
933 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
935 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
936 (avoids "Not in Edit Mode" error).
938 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
940 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
941 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
943 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
945 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
947 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
949 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
951 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
953 1. OnCloseUp Event Handler added to TDBLookupProperties
955 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
956 problem with row size when exception is called.
958 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
960 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
961 in a TCustomComboBox and ignores return key if in a TCustomMemo
963 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
964 keyed in i.e. when autocomplete not performed
966 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
967 console mode applications with all LCL required functions (builtin dialogs and
968 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
969 not included in your project, IBX should compile and link with a console mode program.
970 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
971 console mode application or the IDE will automatically assume that your
972 application is GUI based. Instead, you should include the ibexpressconsolemode package.
974 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
975 to use the built in dialogs and cursor management. IBDialogs is
976 included by default if "ibexpress" is in your project source's "uses" clause.
977 This should be the case for all projects created through the IDE. This is why
978 you do not want to add the ibexpress package to console mode applications. The
979 ibexpressconsolemode package has been created to allow console mode programs
980 to avoid adding LCL dependencies when using IBX, while still having the
981 unit search paths set up correctly.
983 Existing users should check to ensure that the "ibexpress" unit is included in
984 each project's source file (*.lpr).
986 You may find that in order for the IDE to recognise that ibexpressconsolemode
987 exists, you have to first open the package in the IDE and then close it. This
988 adds it to the most recently accessed packages list. To make it permanently
989 available, add the package name to lazarus' file.
991 Thanks to Julio Jiménez for suggesting support of console mode.
993 7. SQL Parser can now accept quoted strings that include new lines
995 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
996 of text on start of edit. This is particularly useful when tabbing to a
997 column and then inserting text.
999 9. New Examples provided for IB Services and ISQLMonitor.
1001 10. Fix error when writing to blob streams that recorded only the last buffer
1002 write in the blob stream. In most cases, this did not cause a problem as the
1003 IB Blob Stream is written in a single write. However, with the TDBImage, write
1004 of a graphic type prefix was lost which caused a problem when the image could
1005 not be automatically recognised.
1007 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
1008 already open" errors due to random numbers used for the cursor name being identical.
1010 12. IBTable: corrected error that could result in an "Index out of bounds" error
1011 when opening the table and the Primary Key is the last or only column in the
1012 table. Thanks to Rick Hoover for the fix.
1014 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
1015 of "UTF-8", and update list of available database character sets. Existing
1016 users should check the current lc_ctype setting in their applications.
1018 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1020 1. Firebird Services: avoid List Index error when opening a service with an
1021 empty Params property.
1023 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1024 Link now set up in Loaded method - avoids occasional failure to apply
1025 SQL markup on initial open.
1027 3. "Employees" example performance improvements when scrolling.
1029 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1030 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1031 random image cached).
1033 5. DBControlGrid: Should now react to changes in panel height at run time.
1035 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1036 even when further rows exist.
1038 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1039 always be derived from panel height and setting this property can cause confusion.
1040 Note for existing projects: to avoid a missing property error at run time,
1041 each form using the DBControlGrid must be opened, updated and saved in the IDE
1042 in order to remove the property value from the lfm.
1045 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1047 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1048 call Prepare before setting parameter values.
1050 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1052 3. Code tidyup and more robust handling of dsql information result vector.
1054 4. Support for centralised handling of transaction status changes. TIBTransaction
1055 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1056 and "AfterExecQuery". The first three are called after the same event is called
1057 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1058 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1059 enable monitoring of transaction status changes for a given transaction to be
1060 handled in a single place. For example, when a change to the dataset occurs
1061 an indicator can be set that shows the user that in order to save changes,
1062 the transaction should be committed. Rather than doing this per dataset, this
1063 can now be done per transaction.
1065 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1066 the dataset is scrolled. However, any changes to the current row are, by default,
1067 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1068 have a new property "DataSetCloseAction" that adds automatic posting of changes
1069 on dataset close. If this property is set to dcDiscardChanges (default) then the
1070 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1071 then IBX will attempt to post any unsaved changes before the dataset is closed
1072 (and after the BeforeClose event handler is called). The exception is when the
1073 dataset is being closed as a result of a transaction rollback. In this case,
1074 no action is taken and any unsaved changes are discarded. This avoids both
1075 unnecessary overhead and the risk that a validation error may occur in the Post
1076 raising an exception and thereby preventing a rollback.
1078 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1079 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1080 width. Display Widths are now corrected by dividing by the max byte width per character.
1081 For UTF8 character sets, the byte width is four and hence the Display Width will be
1082 the byte width divided by 4. The byte width of each character set is determined
1083 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1084 system table. (see also
1086 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1088 8. IBLookupComboEditBox: List should now always be restored to full list when the
1089 control loses focus. Default Key press default interval reduced to 200ms.
1091 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1092 when dataset rows are less than visible rows.
1094 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1095 does not exist or DataSet is empty. More responsive on dataset open. New event
1096 OnRestorePosition. Column sort disabled if no header row.
1098 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1099 while dataset state is dsInsert. Avoids posting errors.
1101 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1102 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1104 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1106 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1107 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1108 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1109 always "posts" the current record regardless or whether or not it may be more appropriate
1110 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1111 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1112 as the first action of the "Post" method and allows the handler to convert the Post
1113 into a Cancel if that is the appropriate action on moving to a different row. This is
1114 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1115 raised here, but it may still be more appropriate to validate a post and signal
1116 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1118 15. On Unix derived systems, the Firebird library name can now be given as a colon
1119 separated list. Each library name on the list is tried in turn, in left to right
1120 order with the first found being used as the firebird library. By default, on Linux,
1121 the library name list is ''. This can be
1122 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1124 Note: when using the, if you prefix the database name with "localhost:"
1125 then it will still attempt to access the database via the Firebird Server and will
1126 require a username and password. If only the pathname is given, then the username
1127 and password should be omitted and the unix file permissions are used to grant
1128 access.
1130 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1132 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1133 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1134 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1135 corresponds to a row of the linked DataSource. Any data aware control on the
1136 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1138 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1139 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1140 takes place during database access. This may be useful when there are performance issues with
1141 the change of cursor. Setting the property to false suppresses the change of cursor.
1143 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1144 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1145 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1146 making all changes permanent immediately rather than when the transaction is explicitly
1147 committed.
1149 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1150 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1152 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1154 Development version only.
1156 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1158 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1159 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1160 "Where" and "Having" clauses to implement user specified filters of arbitrary
1161 complexity.
1163 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1164 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1165 These are:
1167 - TIBLookupComboEditBox
1168 - TIBDynamicGrid
1169 - TIBTreeview
1171 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1172 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1173 to revise the available list and restrict it to items that are prefixed by the
1174 typed text (either case sensitive or case insensitive). Autoinsert allows a
1175 newly typed entry to be added to the list dataset and included in the available
1176 list items.
1178 TIBDynamicGrid is a TDBGrid descendent that provides for:
1179 - automatic resizing of selected columns to fill the available row length
1180 - automatic positioning and sizing of a "totals" control, typically at the
1181 column footer, on a per column basis.
1182 - DataSet resorting on header row click, sorting the dataset by the selected column.
1183 A second click on the same header cell reversed the sort order.
1184 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1185 is automatically expanded and a panel superimposed on it. The panel can have any
1186 number of child controls, typically data aware controls with the same datasource
1187 as the grid allowing for editing of additional fields and more complex editors.
1188 - Reselection of the same row following resorting.
1189 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1190 Its properties are specified on a per column basis and allows for one or more
1191 columns to have their values selected from a list provided by a dataset.
1192 Autocomplete and autoinsert are also available. The existing picklist editor
1193 is unaffected by the extension.
1195 TIBTreeView is a data aware TCustomTreeView.
1197 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1198 zero scale will no longer return an error. An Int64 will be returned instead.
1200 4. TIBTransaction now has events for Before and After Transaction End and a new function
1201 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1203 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1204 repeated multiple times.
1206 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1207 check used to get in the way of using Stored Procedures, and "Update or Insert"
1208 statements.
1210 7. Insert, Modify and Delete property Editors now support Query Generation from
1211 Stored Procedures.
1213 8. Three new examples illustrate the use of the new IB Controls
1216 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1218 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1219 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1220 Gabor Boros for reporting this problem and for testing the improvements).
1222 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1223 See readme.field+param.names in the doc folder.
1225 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1226 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1228 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1230 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1231 actions.
1233 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1234 thanks to Yuriy Kopnin for pointing this out).
1236 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1238 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1239 for both fields and parameter setting.
1241 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1242 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1244 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1245 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1247 11. TIBTable now has a property editor for "MasterFields"
1249 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1250 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1252 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1253 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1256 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1258 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1260 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1262 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1263 it is null. This allows for alternative user defined setting of the generator
1265 Many thanks to Julio Jiménez for this fix
1267 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1268 and suggests that the user may have forgotten to install it.
1270 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1272 1. Conditional compilation used to limit registration of TIntegerField to
1273 Lazarus versions less than 1.1
1275 2. When a database connection is created, character set is now by default set
1276 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1277 1250 to 1254.
1280 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1282 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1285 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1287 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1288 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1290 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1291 package is changed to do this (which it should do).
1293 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1295 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1297 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1299 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1301 4. Property editors should now correctly resize.
1303 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1304 (restored original functionality)
1306 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1307 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
