IBExtract: Identity columns - add addition check for null column for generator name. + +2. IBCustomDataSet: Insert and Modify (Update) queries now recognise and process SQL RETURNING clauses. + The main use for this is for Firebird 3 Identity columns (see IBXDocumentation 6.6.8 for further + information). Values returned as a result of executing an Insert or Update statement + replace existing values in the current row for each corresponding column. + +3. The InsertSQL property editor now shows Firebird 3 Identity columns separate from the Field List. + When InsertSQL is generated, the Identity columns are not included in the list of values to + be inserted. A RETURNING clause is added to the insert statement to return the value of + each Identity column after the insert is executed. + +4. TIBGenerator: small performance improvement by not preparing query each time + a new number is generated. + +5. TIBSQL: Free resources when transaction changed. + +6. Property editor will now sync table name to a System Table when "Include System + Tables" is selected and the query is for a System Table. + +7. Modify Property Editor now generates Update SQL with Computed By fields in Update..Returning clause. + Similarly Insert Property Editor now generates Insert SQL with Computed By fields in + Insert..Returning clause. + +8. Minor Performance improvement to handling of Date/Time types in IBX datasets. Field + values are no longer converted to milliseconds from TDateTime and then back again + the TDateTime (the TDataset approach). + +IBX Change Log version (2.1-0) Fri, 15 Dec 2017 12:20:11 +0000 + +1. IBCustomDataset: Minor change of PChar to PByte for compatibility with fbintf + changes. + +2. IBCustomDataset: Fixed use of incorrect datasize in TIBStringField.SetAsString. + Bug could result in truncated multi-byte character set values. + +3. Changes consequential on moving fbintf character set utility functions from + IFirebirdAPI to IAttachment. + +4. Avoid "Object is nil" error when opening a database with DefaultSystemCodePage = true + +5. IBLookupComboEditBox: avoid race condition when autocompleting text that occasionally + results in autocomplete ignoring prefix text. + +6. IBLookupComboEditBox: Ensure that cursor is not reset to start of text when + entering a new name into the text box. + +7. IBCustomDataset: ensure that TIBStringField uses the field size reported by + Firebird rather than recomputing it. + +8. Property Editor positioning tidy up: All IBX Property editors should now be + screen centre. Previously some were "poDesigned" which may be inappropriate + for multi monitor desktops. + +10. TIBTreeView.FindNode: protect against error if zero length path or empty tree node. + +11. TIBTransaction: On Force Disconnect do not raise an exception when problem ending + a transaction and always reset the object. + +12. TIBQuery tidyup: remove unnecessary call to GetAffectedRows. + +13. TIBXScript: Allow for override of database filename in Create Database statements. + +14. IBLocaldb: Support initialisation of the database from an SQL script in addition + to a gbak format archive. + +15. IBLocaldb: fix problem that stopped the OnSharedDataDir event from being recognised. + +16. IBLocaldb: Drop database if error creating an empty database. + +17. TIBTreeView: improve performance when selecting node - avoid refreshing dataset + unless selected node not in current dataset. + +18. IBServices: SetDBParams method moved from TCustomIBLocalDBSupport (in IBLocalDB package) + to TIBCustomService, and IBlocalDB code tidy up. + +19. IBTreeView: Initialise TIBTreeNode KeyValue to null to avoid unpredictable + behaviour due to uninitialised variable. + +20. IBServices: Correct encoding of isc_spb_prp_write_mode in TIBConfigService from + integer to byte. Ditto isc_spb_prp_reserve_space and isc_spb_prp_access_mode. + +21. IBSQL: When Database changed ensure that all resources are freed. + +22. IBCustomDataset: When database changed ensure that queries an unprepared. + +23. SQL Property Editors now use SynEdit with SQL Highlighter. New features include: + * Line Wrap on SQL Token boundaries (on user command) + * auto-complete table names in drop down list of table names + * Double click on tablename or field name adds to SQL text + +24. IBDataOutput: print statistics using float (%f) format instead of decimal (%d). + +25. IBTreeView: Call to FindNode: param type change from "array of Variant" to + TVariantArray. Seems to avoid memory corruption in Windows (probably a + workaround for a problem in fpc 3.0.4 win64). + +26. IBDatabaseInfo: Code tidy up. Add check for database not assigned or not open. + +27. IBDatabaseInfo: Remove memory leak when accessing database operation counts. + +IBX Change Log version (2.0-2) Fri, 24 Feb 2017 12:17:53 +0000 + +1. TIBDatabase.CreateDatabase: extract full DB Name from SQL using reg ex in order to + include remote system name. + +2. TIBExtract: No longer include comment header and COMMIT statement for empty + tables when data included in output. + +3. Profiling: IBSQL now has conditional compilation flags to enable query performance + and timing information to be written to stdout. This may be used to locate + performance bottlenecks. + +4. SQLParser: only call "OnChanging" event handler when value is different. + +5. IBDynamicGrid: Update handling of navigation keys for a TDateEdit + +6. IBCustomDataset: Set internalunprepared flag when transaction ends. This ensures + that BindFields is called when the query is next activated. Avoids FieldName + not found error. + +7. IBUpdate: This is a new IBX component similar to TIBUpdateSQL. It is more general + purpose and allows the programmer to define any action they want for Update, Insert + or Delete. This may be complex SQL (similar to a Trigger), application specific + filtering of updates, or use of statements such as Grant or Revoke instead of + normal DML. See User Manual for more information. + +IBX Change Log version (2.0-1) Mon, 09 Jan 2017 15:31:49 +0000 + +1. TIBEvents: Fix uninitialised variable that could result in lost events. + +2. TIBExtract: Added support for FB3 "USAGE" privilege. + +3. TIBExtract: data formatted as Charset set "octets" is now output using + hexadecimal notation. + +4. TIBExtract: Binary Blobs and array data can now be embedded in INSERT statements + using a simple XML format. + +5. TIBExtract: extract of individual Triggers and Stored Procedures can now include + grants to these objects. + +6. TIBExtract: Stored Procedures and Views output in dependency order to avoid + dependency problems restoring complex databases. + +7. TIBXScript: This component has been restructured to allow for the processing of + embedded XML in INSERT statements and to support interactive sources in addition + to non-interactive data sources such as files. + +8. TIBXScript: CREATE DATABASE, DROP DATABASE, CONNECT statements are now supported. + +9. TIBXScript: ISQL compatiable Set statements are now supported: + SET SQL DIALECT + SET TERM + SET AUTODDL + SET BAIL + SET ECHO + SET COUNT + SET STATS + SET NAMES + +10. IBVersion unit added to hold current IBX Version Number information. + +11. TIBExtract: Use character rather than byte length for VarChar procedure arguments., + and domain definitions. + +12. TIBExtract: Triggers now use SQL2003 syntax and database and transaction triggers + fully supported. + +13. TIBExtract: when a database dump includes data, the generator values are now also set. + +14: IBSQLEdit: Unit LCLPlatformDef added to uses clauses for lazarus 1.7 and later. + +IBX Change Log version (2.0-0) Tue, 06 Dec 2016 10:33:44 +0000 + +See also doc/IBX4LazarusGuide.pdf for important information on +upgrading to IBX2. + +1. Size property of TIBStringField is now the width in characters of the field + and not the byte length. This applies only to multi-byte character sets such + as UTF8. The original approach aligned with TStringField. However, the TStringField + code is not recognised as a bug and hence this change to align the behaviour. + The TStringField change is expected in fpc 3.2.0. + +2. A new property AutoFieldSize: boolean has been added to TIBStringField. When + true (default) then Size property value saved in the lfm is ignored. Size is + always set from the dynamic information read from the database. It is unclear + why anyone would want to override this and set Size to false. + +3. ibxscript: should now handle correctly a Case..End statement within a procedure + block. + +4. IBDatabase: new property - CreateIfNotExists. If true and database does not + exist when an attempt is made to connect to it (run time only) then an attempt + is made to create the database. + +5. IBDatabase: new event - OnCreateDatabase. This event is called after a database + has been successfully created as a result of a call to CreateDatabase or when + creating a database after it was found not to exist. + +6. DBControlGrid: a race condition could result in the wrong row image being + written to the cache. This has been avoided by a trip round the message + loop before rendering the row image. + +7. DBControlGrid: It is strongly recommended not to open the source DataSet for + a DBControlGrid during a Form's "OnShow" event handler. Under GTK2 this is + known to risk corrupt rendering of row images when the control is first + displayed. If necessary use "Application.QueueAsyncCall" to delay opening + of the dataset (see DBControlGrid examples) until the Form's Window has been created. + +8. DBControlGrid & IBDynamicGrid: Navigation keys should now work correctly with + a TDateEdit control located on an editor panel. + +9. TIBExtract: brought up-to-date plus many bug fixes. + +10. DBControlGrid: Removed memory leak when updating rows. + +11. TIBCMLocalDBSupport: fixed invalid free on upgrade. + +IBX Change Log version (1.4-3) Thu, 22 Sep 2016 18:10:15 +0100 + +1. IBCustomDataset: When calling SetCodePage, no longer request transliteration + when target codepage is CP_NONE. This is a workaround for + http://bugs.freepascal.org/view.php?id=30622. + +2. DBLog option removed from TIBStatisticalService - not supported by server + since Firebird 1.5. + +3. ibxscript: An error is no longer generated for "on commit preserve rows" or + similar. + +4. IBCodePage: updated mapping between codepages and character id. + +5. ftWideString and ftWideMemo withdrawn. There is no UTF16 character set in + Firebird. Character sets with a char width of two are not UTF16. + +6. Strings received from the database are now always transliterated into UTF8 + regardless of the database character set or connection character set. This + is for compatibility with the LCL. + +IBX Change Log version (1.4-2) Thu, 22 Sep 2016 15:25:27 +0100 1. IBBlob: Defer reading of blob until read method called. This avoids having to read in an entire blob just to get the size of the blob. General performance
