1 IBX Change Log version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
3 1. TIBXDataSet and Generators: Generator Names that are not all upper case or
4 not SQL Identifiers are now supported.
6 2. TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
7 passed to the Firebird engine for execution.
9 3. TIBDataSet: Unidirectional datasets now give an error message if an attempt
10 is made to scroll back.
12 4. New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
14 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
15 only enclosed in double quotes in SQL dialect 3 and when it needs to be.
17 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
18 validated. If no match is found in the list of field names and the database has
19 been opened in SQL Dialect 3, then the ListField Name is converted to upper case
20 if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
22 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
23 with fpc 3.2.
25 IBX Change Log version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
28 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
29 and is used to override the default settings in the client side "firebird.conf" This
30 includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
31 Each line of the string list should be a setting in the same format as "firebird.conf".
32 For example "WireCompression = true" in order to request wire compression on the client side.
34 Note: explicit settings in the client side "firebird.conf" appear to take precedence
35 over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
36 also require a compatible setting in the server side "firebird.conf". For example
37 "WireCompression = true" must also be set in the server's "firebird.conf" for wire
38 compression to be used.
40 Whether or not WireCompression or WireCrypt are in use can be checked using the information
41 returned with the Client/Server protocol version. See ibx/examples/dbadmin and
42 ibx/examples/dbinfo for examples of how to display this information.
44 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
45 is a "convenience" property. If set the "WireCompression=true" is added to the
46 ConfigOverrides. If unchecked then this setting is removed.
48 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
49 not "INT64".
51 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
52 These are:
53 property TimestampFormat: string;
54 property DateFormat: string;
55 property TimeFormat: string;
57 Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
58 DATETIME and TIME. The format strings use the standard FPC date/time format
59 characters (see
61 If any of the above properties are set to an empty string, then the locale default
62 is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
63 locale default is extended by appending '.zzz' to include milliseconds.
65 TIBCSVDataOut by default sets these properties to the empty string, while the other
66 two use: ' hh:nn:ss.zzz', '' and 'hh:nn:ss.zzz' respectively.
68 5. New published property for TIBCSVDataOut:
69 property QuoteStrings: boolean (default true)
71 If false then strings are unquoted, otherwise, the QuoteChar property value is
72 used to delimit each and every string in the output.
74 6. New published properties for TIBCSVDataOut:
75 property FieldSeparator: string;
76 property HeaderSeparator: string;
78 Respectively, these provide the separator character(s) used to separate fields
79 in data and header rows. Both default to ','.
81 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
82 TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
83 property OnFormatTextString;
85 This event handler can be used to process text strings before they are included
86 in the output e.g. to replace unprintable characters with alternative strings.
87 This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
89 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
90 Uses "FindParam" if in order to find out if a parameter with a given name exists
91 and without raising and exception if it does not.
93 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
94 consistency with SQL queries.
96 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
97 When true, SQL statement parameter names are parsed case sensitive. Note for
98 TIBDataSet only applies to Select query.
100 11. IBEvents: removing a TIBEvent component from a form should no longer result in
101 an IDE exception.
103 12. LocalDBSupport: initial database creation should now work correctly
104 when the schema source is an sql file.
106 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
107 when defined, this handler will be called by the internal TIBXScript during
108 initial database creation when the schema source is an sql file and may be used
109 to provide a visual indication of progress in console mode.
111 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
112 to true while a new local database is being created and its schema populated.
113 Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
114 when the database is disconnected/connected during the create DB procedure.
116 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
117 are now always ignored and replaced by the user name and password provided as
118 the login parameters for the TIBDatabase referenced from the TIBXScript. The
119 IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
120 completely ignored if this property is true.
122 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
123 to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
124 ImageIndex and SelectImageIndex values on AddNode.
126 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
127 read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
128 the same database connection.
130 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
131 if provided, this should be an conditional SQL expression suitable for
132 including in an SQL Select statement "where" clause. If non-empty and the
133 "Filtered" property is true then the SQL expression provided as the value of
134 the "Filter" property is "ANDed" with any existing condition statement
135 in the SQL statement's "Where" clause.
137 If the "Filter" property is set at run time, the "Filtered" property is true
138 and the dataset is already open, then the dataset is closed and re-opened automatically.
140 The "Filter" condition may include IBX style parameters. In which case, their
141 value must be set by the dataset's "OnBeforeOpen" event handler.
143 This is a public property for TIBDataSet and TIBQuery query and intended for
144 use at run time.
146 Note: The property is a published property of TIBTable. The TIBTable functionality
147 is unaffected by this change.
149 IBX Change Log version (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
151 1. Remove need to check for IsMultiThread by providing access to GUI timers via
152 IBGUIInterface. Note: master/detail delay timer does not apply to console
153 mode apps.
155 2. TIBCustomDataSet: SQLParser ignored if it does not contain a valid select
156 statement. This avoids problems if "Execute Block" is used as the Query.
158 3. IBSQLParser now uses the common SQL tokeniser from fbintf. This replaces the
159 internal SQL tokeniser routines.
161 4. IBSQLParser: new property NotaSelectStmt. Set to true if SQL fails to parse
162 as a select statement, with or without CTEs.
164 5. IBSQLParser: parser now recognises the "ROWS" clause.
166 6. TIBXScript now uses the common SQL tokeniser from fbintf. This replaces the
167 internal SQL tokeniser routines.
169 7. Fix error in TIBXScript processing of "set" statements. This avoids exceptions
170 being raised for valid set statements processed by a data formatter.
172 8. New published property for TIBDatabase and TIBXServicesConnection. This is
173 FirebirdLibraryPathName: string. If not empty it is used to explicitly specify
174 the path of the Firebird Library used by the database/services connection.
176 9. New read only public property for TIBDatabase and TIBXServicesConnection. This
177 is FirebirdAPI and returns the IFirebirdAPI interface used by the database/
178 services connection.
180 10.SQL Property editors now quote parameter names if "Quote identifier" is selected
181 or param name is not a valid SQL identifier.
183 11. IBLookupComboEditBox: In Lazarus 2.0, TDBLookupComboBox takes a more restrictive
184 view of whether the text box should be editable when no DataSource is specified.
185 TIBLookupComboEditBox has been updated to workaround this problem. As long as
186 ReadOnly is false, the text box is editable when no DataSource is specified.
188 12. AllowUseOfFBLIB is now set to "true" at design time. This is to allow use of
189 the FBLIB environment variable. If you do not want to permit this then you
190 must modify the Register procedure in the design/IBDBReg.pas unit to remove
191 this setting.
193 IBX Change Log version (2.3-1) Thu, 25 Oct 2018 14:39:45 +0100
195 1. IBCustomDataset: replace deprecated function ValidUTF8String with call to
196 Utf8EscapeControlChars
198 IBX Change Log version (2.3-0) Mon, 16 Apr 2018 09:48:06 +0100
200 IMPORTANT: the source code tree has been re-organised for IBX 2.3. Please remove
201 all previous copies of the IBX source code tree before installing this release.
203 The IBX packages used by most users have not changed, with one exception. The
204 IBServices unit has been moved to the package iblegacyServices.lpk. To continue
205 to use the IBServices unit in your applications, please add the iblegacyServices
206 to the list of dependencies. To do this, open the Project Inspector and select
207 Add->New Requirement and select "ibLegacyServices" from the list of available
208 packages.
210 1. New unit IBXServices. The IBXServices unit is a re-architectured update of
211 the IBServices unit providing what is intended to be a clearer and easier to
212 use set of IB Services components. See Chapter 10 of the IBX User Guide for
213 more information and the guide to "Firebird Service Management Using IBX".
214 As indicated above, the legacy services components are still available and
215 provided in a separate package. There is no need to update working applications
216 using the older versions except for an additional package dependency.
218 2. The IBX packages and source code tree have been re-organised in an attempt to
219 finally get rid of the "duplicate ppu" warnings. This re-organisation should
220 not affect existing users. Section 2.3 of the IBX User Guide describes the
221 new set of IBX packages.
223 3. The ibx/examples/DBAdmin and the ibx/examples/services example have been
224 updated to use the new Services API components.
226 4. The iblocal package has been updated to use the new Services API components.
228 5. procedure SetAutoAdmin; in the new IBX Services this method is now a member of
229 TIBXSecurityService. It had been wrongly classified in the previous version
230 as a per database configuration item. It is global to a server and hence
231 correctly positioned as part of the Security Package. In the DBAdmin example,
232 the setting has moved to the mappings page.
234 6. TIBXScript: IgnoreCreateDatabase added. If true then CREATE DATABASE statements
235 are ignored.
237 7. TIBDatabase: DropDatabase now ensures that all transactions have been properly
238 closed before the database is dropped. Before and After Disconnect event handlers
239 are also fired.
241 8. TIBTransaction: OnStartTransaction event now fires every time the transaction
242 is started and not just the first time.
244 9. IBDataOutput: Use FormatFloat for all performance statistics to avoid platform
245 depenendency with comp type.
247 10. IBDataOutput: select query data output is now sent to stdout instead of stderr.
249 11. TIBDatabase: Remove regression. If a user login dialog changes the DatabaseName
250 then this is recognised and not ignored.
252 12. TIBDataSet, TIBQuery, TIBTable: additions:
253 function GetRowsAffected(var SelectCount, InsertCount, UpdateCount, DeleteCount: integer): boolean;
254 function GetPerfStatistics(var stats: TPerfCounters): boolean;
255 property EnableStatistics: boolean read FEnableStatistics write SetEnableStatistics;
257 GetRowsAffected returns the affected row counts from the last insert/update/delete
258 if EnableStatistics = true then GetPerfStatistics returns the current stats
259 counters for the select query. Note: stats accumulate after each fetch from
260 the database. To get total query cost after open, call the "Last" method
261 and then GetPerfStatistics.
263 See ibx/examples/consolemode for an example of the use of GetPerfStatistics
265 13. TIBExtract: Identity columns DDL. "Start with clause" now correctly encapsulated
266 in parenthesises.
268 14. TIBExtract: new published property "AlwaysQuoteIdentifiers". If true then in dialect 3
269 SQL identifiers are always delimited by double quotes. If false, then they are
270 only delimited if the identifier is a reserved word, contains lower case or special
271 characters. Set this property to true to retain previous behaviour.
273 15. Insert SQL Property Editor. In Insert Returning Clause, Identity column names
274 are now inserted in double quotes if not Reserved Words or valid SQL Identifiers.
276 16. TIBDataSet, TIBQuery, TIBTable: addition:
277 property MasterDetailDelay: integer {defaults to zero}
279 When non-zero and the dataset is a detail table referencing a master table
280 through either a MasterSource (TIBTable) or a DataSource (TIBDataSet, TIBQuery)
281 then a synchronisation delay is added (in milliseconds) between the master
282 row changing and the detail dataset being re-opened. If the master dataset
283 is scrolled before the delay expires then the delay is reset. This can be used
284 to avoid performance overheads when scrolling through a large master dataset.
286 Note: uses fptimer and hence requires a thread manager. Under Linux the
287 chreads unit must be included in your project. TTimer is not used in order
288 to avoid an LCL dependency. Requires FPC 3.0.2 or later.
290 17. TIBExtract: User role grants now excluded when etGrantsToUser not specified
291 with Extract Option eoDatabase.
293 18. TIBLookupComboEditBox: Workaround added for
294 When a deLayoutChanged event is reported on the ListSource dataset, the
295 combobox text is updated. This allows a listsource (detail) to be in a Master/Detail
296 relationship with the control's datasource (master).
298 19. TIBExtract: Full BigInt value range now supported for Generators/Sequences.
300 20. TIBExtract: Select Procedures (Procedure type 1) now include "SUSPEND;" clause in their
301 stubs. Pedantic fix really, as procedures output in dependency order anyway.
303 21. TIBExtract: Package Headers and Package Bodies are now included in the extracted
304 DDL (Firebird 3 and later only).
306 22. TIBLookupComboBox Autocomplete Fixes:
307 i. Only appended text is now selected after autocomplete.
308 ii. Uppercase keys no longer ignored for autocomplete.
309 iii. Retain Prefix case is now honoured correctly.
310 iv. When a DataSource is assigned, typing after autocomplete now extends prefix
311 before autocomplete performed. i.e. behaviour now the same as when
312 no DataSource assigned.
314 23. TIBXScript: Single Line Comments starting with '--' are now ignored when occurring
315 between SQL statements.
317 24. TIBExtract: New published property CaseSensitiveObjectNames. If false (default) then
318 ObjectNames are converted to upper case before matching against metadata object
319 names, unless the objectname is delimited by double quotes, in which case, the
320 double quotes are removed and the remaining string is used (unmodified) to match
321 against the metadata object name.
323 If true then the ObjectName is used as is without modification and matched
324 against the metadata object name. No attempt is made to remove double quotes.
326 25. TIBExtract: New Extract Types: etDatabaseTriggers and etDDLTriggers. When used
327 with eoTrigger, these extract types can be used to select only Database Triggers,
328 or DDL Triggers or both. Ignored when etTable or etTrigger included in Extract Types.
330 26. TIBXScript: If an exception occurs during the processing of a statement, the
331 statement separate character is now reset to the default (';').
333 27. TIBDatabase: Reconnect method added and used by TIBXScript for reconnect.
335 28. TIBXScript: Transaction is no longer automatically reactivated immediately processing
336 a commit or reconnect statement and instead activated only when next SQL statement
337 is executed.
339 29. TIBSQL.HasField should no longer generate and exception when the field does not exist.
341 30. TIBXScript: case insensitive regex now used when matching statements instead of
342 converting statement to upper case.
344 31. TIBExtract: metadata comments now supported. New published property
345 IncludeMetaDataComments (default true). If true then metadata comments included
346 in extracted DDL. New Extract Object member eoComments. This may be used with
347 ExtractObject method to list all metadata comments.
349 32. TIBExtract: ListObjectNames method added.
351 33. Updated Database component editor to support additional connection string
352 types.
354 IBX Change Log version (2.2-0) Wed, 28 Feb 2018 10:57:45 +0000
362 1. IBExtract: Identity columns - add additional check for null column for generator name.
364 2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses.
365 The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further
366 information). However, this is also a very useful mechanism for returning updated computed by
367 column values. Values returned as a result of executing an Insert or Update statement
368 replace existing values in the current row for each corresponding column.
370 Previously, if a dataset's select query included read only (computed by) fields then
371 an automatic row refresh was performed after an insert or update query had been processed,
372 irrespective of the setting of the "ForcedUpdates" property. This has changed such
373 that an automatic refresh is no longer performed if an insert or update query contains
374 a returning clause that updates one or more fields on the current row. A full row
375 refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any
376 field values and the select query contains read only fields. Use of Insert/update
377 returning should be significantly more efficient than executing a refresh query.
379 This behaviour change is intended to be backwards compatible and there should be no need to change
380 existing programs, other than to improve performance by using the new capability.
382 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as
383 they are called when the dataset row is being deleted, there is no value in
384 updating the current record from the query result. Instead, a new event handler
385 "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and
386 an OnDeleteReturning event handler is provided then it is called with the IResults returned
387 by the query. The event handler can then interrogate the query results and
388 perform whatever action is necessary. For example to confirm, to the user,
389 the deletion of a row with the returned values.
391 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for
392 any Computed By or Identity Columns. The IBTables example has been updated to
393 illustrate the computation of the employee Full Name on update.
395 5. TIBTable: The GeneratorField property is now published.
397 6. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List.
398 When InsertSQL is generated, the Identity columns are not included in the list of values to
399 be inserted. A RETURNING clause is added to the insert statement to return the value of
400 each Identity column after the insert is executed.
402 7. The Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause.
403 Similarly Insert Property Editor now generates Insert SQL with Computed By fields in
404 Insert..Returning clause.
406 8. TIBGenerator: small performance improvement by not preparing query each time
407 a new value is generated.
409 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used.
411 10. Property editors will now sync table name to a System Table when "Include System
412 Tables" is selected and the query is for a System Table.
414 11. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field
415 values are no longer converted to milliseconds from TDateTime and then back again
416 to TDateTime (the conversion to milliseconds is the default TDataset approach).
418 12. Property Editors handling of Stored Procedures.
419 * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and
420 which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select
421 query).
422 * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2).
424 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName
425 can be used to select a package. If non-empty, the stored procedure name is
426 expected to be a stored procedure defined in the specified package and the
427 generated SQL will be as required for a stored procedure located in a package.
429 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include
430 a "Package Name" drop down box to allow selection of a Firebird 3 Package from
431 which a stored procedure can be selected. With no package name selected, non-package
432 stored procedures are listed.
434 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting
435 for password on reconnect.
437 16. TIBDatabase: use IAttachment for connection default character set id, code page
438 and character set name.
440 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise
441 DB info lookups"
443 18. IBExtract: now supports DDL Triggers and Grants to DDL objects.
445 19. Add a property Editor for TIBUpdate.RefreshSQL.
447 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input
448 parameters. This stops an exception being raised when the field cannot be
449 located in the record buffer.
451 21. Property Editors now automatically include System Tables when opened and when the query table
452 is a System Table.
454 22. IBServices: SQRB and SRB buffers are now reset when service query throws an exception.
455 This avoids errors due to a stale SQRB or SRB being used for the next query.
457 23. IBServices: Service attach parameters now include "expected_db". This is used to
458 add the SPB item isc_spb_expected_db. This names a database using
459 an alternative Security Database (FB3 onwards) and allows (e.g. backup/restore) using such a
460 database. examples/services re-written to illustrate use of "expected_db".
462 24. IBServices: TIBControlAndQueryService.WriteNextChunk no longer ignores isc_info_svc_timeout.
463 This avoids truncated backups when the server returns a timeout (busy) response.
465 25. TIBDatabase: isc_dpb_page_size now supported as a database parameter when using TIBDatabase.CreateDatabase.
467 26. TIBDatabase: DatabaseName property may now be prefixed by $TEMP$ or $DATADIR$ for local
468 databasenames. These are respectively expanded to the local system's temp directory
469 (including trailing delimiter) or to a prescribed data directory (including
470 trailing delimiter). Under Unix systems the data directory is a hidden directory
471 in the user's home directory. The hidden directory name is either the string returned
472 from the SysUtils "Vendor Name" or "IBX" if empty. In either case prefixed by a '.'.
473 Under Windows, the directory is the same as the Data Directory as decribed
474 above but instead prefixed by the User's application data path. These may be
475 used to improve application portability for Personal Databases.
477 27. TIBTable: FieldDefs property is no longer published. Due to the use of TIBFieldDef
478 this has not worked for a long time and is not useful either. FieldDefs should be
479 managed using the Fields Editor as with any other dataset. To access the fields
480 editor for a TIBTable component, double click on the component. The fields editor
481 is then displayed.
483 28. TIBDatabaseInfo: new properties/function
484 * DateDBCreated (returns date/time database created)
485 * TransactionCount (returns no. of active transactions)
486 * GetDatabasePage(PageNo: integer) (returns contents of specified database page - SYSDBA only).
487 * PagesFree (Firebird 3 or later)
488 * PagesUsed (Firebird 3 or later)
489 * Encrypted (returns true if database encrypted. (Firebird 3.0.3 or later only)
490 * EncryptionKeyName (returns the name of the encryption key if any (Firebird 3.0.3 or later only)
492 29. IBServices classes now provided the decoded release number in the (array) property ServerVersionNo.
494 30. TIBSecurityService now supports display/modification of the User Admin Role (Firebird 2.5 and later).
496 31. TIBConfigService now has a procedure SetAutoAdmin(Value: boolean) to enable/disable
497 the automtic mapping of privileged OS users to the RDB$ADMIN role (Firebird 2.5 and later).
499 32. TIBBackupService: New Option - NoDBTriggers equivalent to -nodbtriggers switch introduced
500 in the gbak utility at V.2.1 to prevent database-level and transaction-level triggers from
501 firing during backup and restore.
503 33. Both TIBBackupService and TIBRestoreService now support backup/restore statistics options
504 for verbose output using the new property "StatisticsRequested".
505 see
507 34. TIBRestoreService: now supports new options RestoreMetaDataOnly (Firebird 2.5 and later).
509 35. TIBOnlineValidationService component added to the IBServices and the "Firebird Admin"
510 palette. This uses the online validation feature added in Firebird 2.5. The
511 services's properties enable inclusion/exclusion of tables and indexes using
512 regular expressions. See.
515 36. IBServices: procedure TIBConfigService.SetNoLinger added to set no linger
516 option on a database.
518 37. TIBCustomService: Assign method implemented to allow copying of service login
519 context between service API components. "Detach" method now only detaches
520 service when last reference to the service interface detaches. Tidy up of
521 code for SetActive and Attach methods including password hiding.
523 38. TIBDatabase: new properties: AuthenticationMethod and RemoteProtocol. Read only
524 and used to determine the auth method and protocol used for the connection.
526 39. TIBDatabase: ensure that SQLDialect setting is used when creating a database using
527 a Create Database Statement generated by IBX.
529 40. All IBServices now have an additional published property "PortNo". This may
530 be set to a non-standard port number when necessary. If zero then the default
531 port number is used.
533 41: TIBLookupComboeditBox: Ensure dataset updated when change selected with the keyboard
534 and not just the mouse.
536 42. TIBCustomDataset: reopen query if already active when a TIBControlLink is added.
538 43. TIBTreeview: new ImageIndexField and SelectedIndexField Property allows the
539 image index and selected image index for each node to be set from a database field.
541 44. TIBExtract: new extract type (etGrantsToUser) for use with eoDatabase. If included
542 then database schema includes grants to all users. If not present then the
543 only user grants included are those to User PUBLIC.
545 45. TIBTreeView: performance improvement. When expanding include both expanded node
546 and child nodes in dataset.
549 IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000
551 1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf
552 changes.
554 2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString.
555 Bug could result in truncated multi-byte character set values.
557 3. Changes consequential on moving fbintf character set utility functions from
558 IFirebirdAPI to IAttachment.
560 4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true
562 5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally
563 results in autocomplete ignoring prefix text.
565 6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when
566 entering a new name into the text box.
568 7. IBCustomDataset: ensure that TIBStringField uses the field size reported by
569 Firebird rather than recomputing it.
571 8. Property Editor positioning tidy up: All IBX Property editors should now be
572 screen centre. Previously some were "poDesigned" which may be inappropriate
573 for multi monitor desktops.
575 10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node.
577 11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending
578 a transaction and always reset the object.
580 12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows.
582 13. TIBXScript: Allow for override of database filename in Create Database statements.
584 14. IBLocaldb: Support initialisation of the database from an SQL script in addition
585 to a gbak format archive.
587 15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised.
589 16. IBLocaldb: Drop database if error creating an empty database.
591 17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset
592 unless selected node not in current dataset.
594 18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package)
595 to TIBCustomService, and IBlocalDB code tidy up.
597 19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable
598 behaviour due to uninitialised variable.
600 20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from
601 integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode.
603 21. IBSQL: When Database changed ensure that all resources are freed.
605 22. IBCustomDataset: When database changed ensure that queries an unprepared.
607 23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include:
608 * Line Wrap on SQL Token boundaries (on user command)
609 * auto-complete table names in drop down list of table names
610 * Double click on tablename or field name adds to SQL text
612 24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d).
614 25. IBTreeView: Call to FindNode: param type change from "array of Variant" to
615 TVariantArray. Seems to avoid memory corruption in Windows (probably a
616 workaround for a problem in fpc 3.0.4 win64).
618 26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open.
620 27. IBDatabaseInfo: Remove memory leak when accessing database operation counts.
622 IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000
624 1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to
625 include remote system name.
627 2. TIBExtract: No longer include comment header and COMMIT statement for empty
628 tables when data included in output.
630 3. Profiling: IBSQL now has conditional compilation flags to enable query performance
631 and timing information to be written to stdout. This may be used to locate
632 performance bottlenecks.
634 4. SQLParser: only call "OnChanging" event handler when value is different.
636 5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit
638 6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures
639 that BindFields is called when the query is next activated. Avoids FieldName
640 not found error.
642 7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general
643 purpose and allows the programmer to define any action they want for Update, Insert
644 or Delete. This may be complex SQL (similar to a Trigger), application specific
645 filtering of updates, or use of statements such as Grant or Revoke instead of
646 normal DML. See User Manual for more information.
648 IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000
650 1. TIBEvents: Fix uninitialised variable that could result in lost events.
652 2. TIBExtract: Added support for FB3 "USAGE" privilege.
654 3. TIBExtract: data formatted as Charset set "octets" is now output using
655 hexadecimal notation.
657 4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements
658 using a simple XML format.
660 5. TIBExtract: extract of individual Triggers and Stored Procedures can now include
661 grants to these objects.
663 6. TIBExtract: Stored Procedures and Views output in dependency order to avoid
664 dependency problems restoring complex databases.
666 7. TIBXScript: This component has been restructured to allow for the processing of
667 embedded XML in INSERT statements and to support interactive sources in addition
668 to non-interactive data sources such as files.
670 8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported.
672 9. TIBXScript: ISQL compatiable Set statements are now supported:
680 SET NAMES <character set>
682 10. IBVersion unit added to hold current IBX Version Number information.
684 11. TIBExtract: Use character rather than byte length for VarChar procedure arguments.,
685 and domain definitions.
687 12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers
688 fully supported.
690 13. TIBExtract: when a database dump includes data, the generator values are now also set.
692 14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later.
694 IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000
696 See also doc/IBX4LazarusGuide.pdf for important information on
697 upgrading to IBX2.
699 1. Size property of TIBStringField is now the width in characters of the field
700 and not the byte length. This applies only to multi-byte character sets such
701 as UTF8. The original approach aligned with TStringField. However, the TStringField
702 code is not recognised as a bug and hence this change to align the behaviour.
703 The TStringField change is expected in fpc 3.2.0.
705 2. A new property AutoFieldSize: boolean has been added to TIBStringField. When
706 true (default) then Size property value saved in the lfm is ignored. Size is
707 always set from the dynamic information read from the database. It is unclear
708 why anyone would want to override this and set Size to false.
710 3. ibxscript: should now handle correctly a Case..End statement within a procedure
711 block.
713 4. IBDatabase: new property - CreateIfNotExists. If true and database does not
714 exist when an attempt is made to connect to it (run time only) then an attempt
715 is made to create the database.
717 5. IBDatabase: new event - OnCreateDatabase. This event is called after a database
718 has been successfully created as a result of a call to CreateDatabase or when
719 creating a database after it was found not to exist.
721 6. DBControlGrid: a race condition could result in the wrong row image being
722 written to the cache. This has been avoided by a trip round the message
723 loop before rendering the row image.
725 7. DBControlGrid: It is strongly recommended not to open the source DataSet for
726 a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is
727 known to risk corrupt rendering of row images when the control is first
728 displayed. If necessary use "Application.QueueAsyncCall" to delay opening
729 of the dataset (see DBControlGrid examples) until the Form's Window has been created.
731 8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with
732 a TDateEdit control located on an editor panel.
734 9. TIBExtract: brought up-to-date plus many bug fixes.
736 10. DBControlGrid: Removed memory leak when updating rows.
738 11. TIBCMLocalDBSupport: fixed invalid free on upgrade.
740 IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100
742 1. IBCustomDataset: When calling SetCodePage, no longer request transliteration
743 when target codepage is CP_NONE. This is a workaround for
746 2. DBLog option removed from TIBStatisticalService - not supported by server
747 since Firebird 1.5.
749 3. ibxscript: An error is no longer generated for "on commit preserve rows" or
750 similar.
752 4. IBCodePage: updated mapping between codepages and character id.
754 5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in
755 Firebird. Character sets with a char width of two are not UTF16.
757 6. Strings received from the database are now always transliterated into UTF8
758 regardless of the database character set or connection character set. This
759 is for compatibility with the LCL.
761 IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100
763 1. IBBlob: Defer reading of blob until read method called. This avoids having to
764 read in an entire blob just to get the size of the blob. General performance
765 improvement when opening datasets containing blobs.
767 2. Clearing a Blob now sets the corresponding field's modified flag.
769 3. IBLookupCombo: When not performing auto-complete, original query sort order
770 is now used.
772 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically
773 determined.
775 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened.
777 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post
778 lazarus 1.6.0
780 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages"
781 compilation error.
783 IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100
785 1. No character set specified for connection: when a text blob is retrieved, the
786 character set is determined by looking up the native character set using then
787 Firebird API. Otherwise a text mode blob is assumed to have the same character
788 set as the connection.
790 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow
791 for Login Dialog returing a change to the database path.
793 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name
794 to be changed from that given in the TIBDatabase/TIBServer component and for the
795 entered value to be saved on a project specific basis (design time only).
797 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the
798 column fieldname. If they are the same then it is acts as a look up for the KeyValue
799 Otherwise, it sets the column text to the selected ListField Value.
801 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating
802 column width.
804 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given
805 and a case insensitive search is requested.
807 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls
808 or column ListSource.
810 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an
811 unprepare) when closing and the text has not changed.
813 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer.
814 Less likely to cause a cursor re-use error on Windows.
816 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin.
817 Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0.
819 11. TIBTreeView: Guard against nil destination on record changed
821 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a
822 string type with the code page set to reflect the returned field encoding after
823 Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for
824 earlier versions.
826 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString
827 will now result in transliteration to the code page specified for the Firebird driver
828 if the assigned string has a different code page. FPC 3.0.0 onwards only.
830 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter
831 is ignored and the lc_ctype value, when the database is opened, is set to align with
832 the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure
833 platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC
834 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when
835 the GETACP is used to determine the Windows code page.
837 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set
838 name used as the lc_ctype when the database was opened. Only valid while the
839 Database is connected.
841 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage
842 id that corresponds to the DefaultCharSetName.
844 IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000
846 1. Unix: If Firebird Embedded Server shared object is loaded and a local database
847 path is given and database attach fails due to access permission issues on the
848 temp directory or security database, then the attach is retried with "localhost:"
849 prefixing the databasename. This should avoid problems when the database has to
850 be accessed by a local (e.g. classic) server and libfbembed is used.
852 2. Windows: revised search order for Firebird DLL:
853 i. The Firebird Embedded Server in the application Directory.
854 ii. If the FIREBIRD environment variable is set then the directory this
855 points to is searched for the FB Client DLL and then then underlying
856 "bin" directory.
857 iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances
858 is used to locate the Firebird installation directory and the underlying
859 "bin" directory is searched for the FB Client DLL.
860 iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x
861 are searched for the FB Client DLL.
862 v. The PATH Environment variable is used to search for the FB Client DLL.
863 vi. Finally the PATH Environment variable is used to search for IBASE.DLL.
865 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine.
866 See doc/readme.scriptengine and example applications.
868 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to
869 simplify the use of the embedded firebird server on both Linux and Windows platforms.
870 See dpc/readme.localdatabase and example applications.
872 5. IBDynamicGrid: Reordering on column header click should now also work for
873 dynamic columns.
875 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition
876 between incrementing/decrementing the lock count and signalling the event.
878 IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000
880 1.3.2 was never formally released and only made available as beta copies.
882 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo
884 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column
886 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early
888 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset
889 i.e. when it is a calculated field
891 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid.
892 This problem was due to a race condition between recalculating row heights and
893 determining which row was selected by the mouse click. The row height calculation
894 is now deferred by an extra trip round the message loop allowing the row to
895 be always calculated on the current grid layout rather than risking it being
896 calculated on the grid layout after the expanded row has been shrunk.
898 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on
899 Windows.
901 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer;
902 These properties allow the (Firebird) character set name for the field and the max number of bytes per character
903 to be determined at runtime. See doc/readme.charactersets.html.
905 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from
906 TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html.
908 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from
909 TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of
910 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html.
912 Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated
913 from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero
914 implies no truncation.
916 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active.
918 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state
919 (avoids "Not in Edit Mode" error).
921 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator.
923 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling
924 DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control.
926 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent.
928 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls
930 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked.
932 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened.
934 IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100
936 1. OnCloseUp Event Handler added to TDBLookupProperties
938 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids
939 problem with row size when exception is called.
941 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit.
943 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if
944 in a TCustomComboBox and ignores return key if in a TCustomMemo
946 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text
947 keyed in i.e. when autocomplete not performed
949 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support
950 console mode applications with all LCL required functions (builtin dialogs and
951 cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is
952 not included in your project, IBX should compile and link with a console mode program.
953 See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a
954 console mode application or the IDE will automatically assume that your
955 application is GUI based. Instead, you should include the ibexpressconsolemode package.
957 IMPORTANT NOTE: IBDialogs must be included in GUI applications in order
958 to use the built in dialogs and cursor management. IBDialogs is
959 included by default if "ibexpress" is in your project source's "uses" clause.
960 This should be the case for all projects created through the IDE. This is why
961 you do not want to add the ibexpress package to console mode applications. The
962 ibexpressconsolemode package has been created to allow console mode programs
963 to avoid adding LCL dependencies when using IBX, while still having the
964 unit search paths set up correctly.
966 Existing users should check to ensure that the "ibexpress" unit is included in
967 each project's source file (*.lpr).
969 You may find that in order for the IDE to recognise that ibexpressconsolemode
970 exists, you have to first open the package in the IDE and then close it. This
971 adds it to the most recently accessed packages list. To make it permanently
972 available, add the package name to lazarus' file.
974 Thanks to Julio Jiménez for suggesting support of console mode.
976 7. SQL Parser can now accept quoted strings that include new lines
978 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end
979 of text on start of edit. This is particularly useful when tabbing to a
980 column and then inserting text.
982 9. New Examples provided for IB Services and ISQLMonitor.
984 10. Fix error when writing to blob streams that recorded only the last buffer
985 write in the blob stream. In most cases, this did not cause a problem as the
986 IB Blob Stream is written in a single write. However, with the TDBImage, write
987 of a graphic type prefix was lost which caused a problem when the image could
988 not be automatically recognised.
990 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor
991 already open" errors due to random numbers used for the cursor name being identical.
993 12. IBTable: corrected error that could result in an "Index out of bounds" error
994 when opening the table and the Primary Key is the last or only column in the
995 table. Thanks to Rick Hoover for the fix.
997 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead
998 of "UTF-8", and update list of available database character sets. Existing
999 users should check the current lc_ctype setting in their applications.
1001 IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100
1003 1. Firebird Services: avoid List Index error when opening a service with an
1004 empty Params property.
1006 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3.
1007 Link now set up in Loaded method - avoids occasional failure to apply
1008 SQL markup on initial open.
1010 3. "Employees" example performance improvements when scrolling.
1012 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a
1013 TFrame. Force recaching of selected frame to avoid GTK race (results in a
1014 random image cached).
1016 5. DBControlGrid: Should now react to changes in panel height at run time.
1018 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid
1019 even when further rows exist.
1021 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should
1022 always be derived from panel height and setting this property can cause confusion.
1023 Note for existing projects: to avoid a missing property error at run time,
1024 each form using the DBControlGrid must be opened, updated and saved in the IDE
1025 in order to remove the property value from the lfm.
1028 IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100
1030 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always
1031 call Prepare before setting parameter values.
1033 2. Error message on ParamByName (all cases) not found now includes name of missing parameter.
1035 3. Code tidyup and more robust handling of dsql information result vector.
1037 4. Support for centralised handling of transaction status changes. TIBTransaction
1038 has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost"
1039 and "AfterExecQuery". The first three are called after the same event is called
1040 for an IBCustomDataSet descendent using the Transaction. The fourth is called
1041 after a call to TIBSQL.ExecQuery, again using this transaction. These new events
1042 enable monitoring of transaction status changes for a given transaction to be
1043 handled in a single place. For example, when a change to the dataset occurs
1044 an indicator can be set that shows the user that in order to save changes,
1045 the transaction should be committed. Rather than doing this per dataset, this
1046 can now be done per transaction.
1048 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when
1049 the dataset is scrolled. However, any changes to the current row are, by default,
1050 discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now
1051 have a new property "DataSetCloseAction" that adds automatic posting of changes
1052 on dataset close. If this property is set to dcDiscardChanges (default) then the
1053 behaviour is unchanged from previous versions. if the value is set to dcSaveChanges
1054 then IBX will attempt to post any unsaved changes before the dataset is closed
1055 (and after the BeforeClose event handler is called). The exception is when the
1056 dataset is being closed as a result of a transaction rollback. In this case,
1057 no action is taken and any unsaved changes are discarded. This avoids both
1058 unnecessary overhead and the risk that a validation error may occur in the Post
1059 raising an exception and thereby preventing a rollback.
1061 6. String Field sizes and Display Widths should now be correct for multi-byte character sets.
1062 In earlier versions, the Display Width was set to the maximum byte width rather than the character
1063 width. Display Widths are now corrected by dividing by the max byte width per character.
1064 For UTF8 character sets, the byte width is four and hence the Display Width will be
1065 the byte width divided by 4. The byte width of each character set is determined
1066 dynamically when the database connection is estabished from the RDB$CHARACTER_SETS
1067 system table. (see also
1069 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string.
1071 8. IBLookupComboEditBox: List should now always be restored to full list when the
1072 control loses focus. Default Key press default interval reduced to 200ms.
1074 9. DBControlGrid: Ensure that selection is changed to newly appended row, even
1075 when dataset rows are less than visible rows.
1077 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource
1078 does not exist or DataSet is empty. More responsive on dataset open. New event
1079 OnRestorePosition. Column sort disabled if no header row.
1081 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset
1082 while dataset state is dsInsert. Avoids posting errors.
1084 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to
1085 avoid conflict with DisableControls/EnableControls with Master/Detail linked tables.
1087 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes.
1089 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced
1090 to solve a specific problem. That is when the dataset cursor is moved (e.g. by
1091 a grid mouse click and the current row is being edited or inserted. In this case, TDataset
1092 always "posts" the current record regardless or whether or not it may be more appropriate
1093 to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the
1094 "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called
1095 as the first action of the "Post" method and allows the handler to convert the Post
1096 into a Cancel if that is the appropriate action on moving to a different row. This is
1097 achieved by returning with "CancelPost" argument set to true. Note that an exception could be
1098 raised here, but it may still be more appropriate to validate a post and signal
1099 a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml)
1101 15. On Unix derived systems, the Firebird library name can now be given as a colon
1102 separated list. Each library name on the list is tried in turn, in left to right
1103 order with the first found being used as the firebird library. By default, on Linux,
1104 the library name list is ''. This can be
1105 overidden by the FBLIB environment variable or the OnGetLibraryName function.
1107 Note: when using the, if you prefix the database name with "localhost:"
1108 then it will still attempt to access the database via the Firebird Server and will
1109 require a username and password. If only the pathname is given, then the username
1110 and password should be omitted and the unix file permissions are used to grant
1111 access.
1113 IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000
1115 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike
1116 rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid
1117 that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row
1118 corresponds to a row of the linked DataSource. Any data aware control on the
1119 replicated (e.g.) TPanel will then appear to have the appropriate value for the row.
1121 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase.
1122 When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change
1123 takes place during database access. This may be useful when there are performance issues with
1124 the change of cursor. Setting the property to false suppresses the change of cursor.
1126 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery
1127 and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to
1128 Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of
1129 making all changes permanent immediately rather than when the transaction is explicitly
1130 committed.
1132 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still
1133 using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature.
1135 IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000
1137 Development version only.
1139 IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000
1141 1. An internal select SQL Parser is now available for TIBCustomDataset descendents.
1142 This is typically used during an "OnBeforeOpen" event handler to manipulate the
1143 "Where" and "Having" clauses to implement user specified filters of arbitrary
1144 complexity.
1146 2. A new Component Palette entry "Firebird Data Controls" is now available. This has
1147 three new data aware controls dependent on IBX and which make use of the SQL Parser.
1148 These are:
1150 - TIBLookupComboEditBox
1151 - TIBDynamicGrid
1152 - TIBTreeview
1154 TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete"
1155 of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation
1156 to revise the available list and restrict it to items that are prefixed by the
1157 typed text (either case sensitive or case insensitive). Autoinsert allows a
1158 newly typed entry to be added to the list dataset and included in the available
1159 list items.
1161 TIBDynamicGrid is a TDBGrid descendent that provides for:
1162 - automatic resizing of selected columns to fill the available row length
1163 - automatic positioning and sizing of a "totals" control, typically at the
1164 column footer, on a per column basis.
1165 - DataSet resorting on header row click, sorting the dataset by the selected column.
1166 A second click on the same header cell reversed the sort order.
1167 - Support for a "Panel Editor". That is on clicking the indicator column, the row
1168 is automatically expanded and a panel superimposed on it. The panel can have any
1169 number of child controls, typically data aware controls with the same datasource
1170 as the grid allowing for editing of additional fields and more complex editors.
1171 - Reselection of the same row following resorting.
1172 - A new cell editor that provides the same functionality as TIBLookupComboEditBox.
1173 Its properties are specified on a per column basis and allows for one or more
1174 columns to have their values selected from a list provided by a dataset.
1175 Autocomplete and autoinsert are also available. The existing picklist editor
1176 is unaffected by the extension.
1178 TIBTreeView is a data aware TCustomTreeView.
1180 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a
1181 zero scale will no longer return an error. An Int64 will be returned instead.
1183 4. TIBTransaction now has events for Before and After Transaction End and a new function
1184 "GetEndAction" allowing the EndAction to be accessed by these event handlers.
1186 5. TIBQuery can now handle correctly queries which contain the same keyword parameter
1187 repeated multiple times.
1189 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error
1190 check used to get in the way of using Stored Procedures, and "Update or Insert"
1191 statements.
1193 7. Insert, Modify and Delete property Editors now support Query Generation from
1194 Stored Procedures.
1196 8. Three new examples illustrate the use of the new IB Controls
1199 IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100
1201 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter
1202 setting performance. See "readme.field+param.names in the doc folder.(Thanks to
1203 Gabor Boros for reporting this problem and for testing the improvements).
1205 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case.
1206 See readme.field+param.names in the doc folder.
1208 3. IBX SQL Editors will now automatically add double quotes around column names when the database
1209 dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word.
1211 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc
1213 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once"
1214 actions.
1216 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with
1217 thanks to Yuriy Kopnin for pointing this out).
1219 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet.
1221 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types
1222 for both fields and parameter setting.
1224 9. Changes to the Select SQL in an IBCustomDataset descendent should now be
1225 visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property.
1227 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test,
1228 when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true.
1230 11. TIBTable now has a property editor for "MasterFields"
1232 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the
1233 GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters.
1235 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination
1236 of settings is unrecognised. Selecting this radio button has no effect on the settings.
1239 IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000
1241 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change.
1243 IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000
1245 1. In a TIBCustomDataset descendent, a generator now only sets the value when
1246 it is null. This allows for alternative user defined setting of the generator
1248 Many thanks to Julio Jiménez for this fix
1250 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library
1251 and suggests that the user may have forgotten to install it.
1253 IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000
1255 1. Conditional compilation used to limit registration of TIntegerField to
1256 Lazarus versions less than 1.1
1258 2. When a database connection is created, character set is now by default set
1259 to UTF8 (Unix) or to the current Windows code page (Windows) if in the range
1260 1250 to 1254.
1263 IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100
1265 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change.
1268 IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100
1270 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0
1271 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1
1273 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB
1274 package is changed to do this (which it should do).
1276 IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100
1278 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close).
1280 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance)
1282 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes
1284 4. Property editors should now correctly resize.
1286 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox
1287 (restored original functionality)
1289 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird
1290 library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
