IBX Change Log version (2.2-0) Thu, 25 Jan 2018 13:56:39 +0000 1. IBExtract: Identity columns - add additional 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). However, this is also a very useful mechanism for returning updated computed by column values. Values returned as a result of executing an Insert or Update statement replace existing values in the current row for each corresponding column. Previously, if a dataset's select query included read only (computed by) fields then an automatic row refresh was performed after an insert or update query had been processed, irrespective of the setting of the "ForcedUpdates" property. This has changed such that an automatic refresh is no longer performed if an insert or update query contains a returning clause that updates one or more fields on the current row. A full row refresh is only performed if (a) ForcedRefresh is true or (b) the query does not return any field values and the select query contains read only fields. Use of Insert/update returning should be significantly more efficient than executing a refresh query. This behaviour change is intended to be backwards compatible and there should be no need to change existing programs, other than to improve performance by using the new capability. 3. IBCustomDataSet: DELETE...RETURNING queries are now also recognised. However, as they are called when the dataset row is being deleted, there is no value in updating the current record from the query result. Instead, a new event handler "OnDeleteReturning" is provided. If a DELETE...RETURNING query is execute and an OnDeleteReturning event handler is provided then it is called with the IResults returned by the query. The event handler can then interrogate the query results and perform whatever action is necessary. For example to confirm, to the user, the deletion of a row with the returned values. 4. TIBTable: generated Insert and Update SQL now include a RETURNING clause for any Computed By or Identity Columns. The IBTables example has been updated to illustrate the computation of the employee Full Name on update. 5. TIBTable: The GeneratorField property is now published. 6. 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. 7. The 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. TIBGenerator: small performance improvement by not preparing query each time a new value is generated. 9. TIBSQL: Free resources when transaction changed - ensures new transaction is used. 10. Property editors will now sync table name to a System Table when "Include System Tables" is selected and the query is for a System Table. 11. 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 to TDateTime (the conversion to milliseconds is the default TDataset approach). 12. Property Editors handling of Stored Procedures. * Select and Refresh: only show a list of stored procedures that return multiple rows (proc type 1) and which have a non-empty list of output parameters (i.e. stored procedures that may be used in a select query). * Modify and Insert: only show a list of stored procedures that return at most a singleton row (proc type 2). 13. IBStoredProc: Now supports Firebird 3 Package Names. A new published property PackageName can be used to select a package. If non-empty, the stored procedure name is expected to be a stored procedure defined in the specified package and the generated SQL will be as required for a stored procedure located in a package. 14. Select, Refresh, Insert, Modify, Delete and TIBSQL SQL Property Editors now include a "Package Name" drop down box to allow selection of a Firebird 3 Package from which a stored procedure can be selected. With no package name selected, non-package stored procedures are listed. 15. TIBXScript: turn off database login prompt when reconnecting - this avoids prompting for password on reconnect. 16. IBDatabase: use IAttachment for connection default character set id, code page and character set name. 17. TIBDatabaseInfo: cache ODS Version information on first request in order to minimise DB info lookups" 18. IBExtract: now supports DDL Triggers. 19. Add a property Editor for TIBUpdate.RefreshSQL. 20. IBUpdate: Ignore non-data (e.g. calculated) fields when assembling list of input parameters. This stops an exception being raised when the field cannot be located in the record buffer. 21. Property Editors now automatically include System Tables when opened and when the query table is a System Table. 22. FB3UserManager example added to illustrate use if IBX for managing user logins, passwords and connections using IBX and with single or multiple security databases. 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 improvement when opening datasets containing blobs. 2. Clearing a Blob now sets the corresponding field's modified flag. 3. IBLookupCombo: When not performing auto-complete, original query sort order is now used. 4. IBDynamicGrid: Add OnSelectEditor event. Allows editor panel to be dynamically determined. 5. IBDynamicGrid: Recompute column widths after dataset closed and re-opened. 6. IBLookupCombo: LazUTF8 added to uses clause to avoid compilation problems post lazarus 1.6.0 7. IBControls. Removed "runtime" from list of paths to avoid "multiple packages" compilation error. IBX Change Log version (1.4-1) Tue, 17 May 2016 09:14:51 +0100 1. No character set specified for connection: when a text blob is retrieved, the character set is determined by looking up the native character set using then Firebird API. Otherwise a text mode blob is assumed to have the same character set as the connection. 2. TIBGUIInterface: this is an internal interface. Minor type changes to allow for Login Dialog returing a change to the database path. 3. Design Time Database and Server login Dialogs now allow the Database Name/Server Name to be changed from that given in the TIBDatabase/TIBServer component and for the entered value to be saved on a project specific basis (design time only). 4. IBDynamicGrid: TDBLookupCellEditor now compares its DataFieldName with the column fieldname. If they are the same then it is acts as a look up for the KeyValue Otherwise, it sets the column text to the selected ListField Value. 5. IBDynamicGrid: Only visible columns are now taken into account When recalculating column width. 6. IBLookupComboEditBox: Fix error with autocomplete query when a RelationName is given and a case insensitive search is requested. 7. IBDynamicGrid: No longer ignores notifications removing Column Totals controls or column ListSource. 8. IBQuery: no longer performs unnecessary refresh of SQL Text (and hence avoids an unprepare) when closing and the text has not changed. 9. IBSQL: Base the cursor name on a GUID instead of a hexstr version of the class pointer. Less likely to cause a cursor re-use error on Windows. 10.SV5IPC: include workaround for OSX. FPC 3.0.0 has broken ipc module for darwin. Expected to be fixed in 3.0.2. Hence workaround only applies to 3.0.0. 11. TIBTreeView: Guard against nil destination on record changed 12. AnsiString Code page support: TIBStringField.AsString and TIBMemoField.AsString now return a string type with the code page set to reflect the returned field encoding after Firebird driver transliteration, if any. FPC 3.0.0 onwards only. Behaviour unchanged for earlier versions. 13. AnsiString Code page support: Assigning to TIBStringField.AsString and TIBMemoField.AsString will now result in transliteration to the code page specified for the Firebird driver if the assigned string has a different code page. FPC 3.0.0 onwards only. 14. TIBDatabase: new property UseDefaultSystemCodePage. When set any lc_ctype parameter is ignored and the lc_ctype value, when the database is opened, is set to align with the DefaultSystemCodePage (FPC 3.0.0 onwards). Normally, this is what you want and should ensure platform independence. Note: this applies to FPC 3.0.0 and earlier versions. Pre FPC 3.0.0, when this property is true, the lc_ctype is UTF8 except under windows when the GETACP is used to determine the Windows code page. 15. TIBDatabase: new property DefaultCharSetName. This is the Firebird character set name used as the lc_ctype when the database was opened. Only valid while the Database is connected. 16. TIBDatabase: new property DefaultCodePage (FPC >=3.0.0 only). This is the codepage id that corresponds to the DefaultCharSetName. IBX Change Log version (1.4-0) Mon, 15 Feb 2016 14:44:24 +0000 1. Unix: If Firebird Embedded Server shared object is loaded and a local database path is given and database attach fails due to access permission issues on the temp directory or security database, then the attach is retried with "localhost:" prefixing the databasename. This should avoid problems when the database has to be accessed by a local (e.g. classic) server and libfbembed is used. 2. Windows: revised search order for Firebird DLL: i. The Firebird Embedded Server in the application Directory. ii. If the FIREBIRD environment variable is set then the directory this points to is searched for the FB Client DLL and then then underlying "bin" directory. iii. Registry Key HKEY_LOCAL_MACHINE\SOFTWARE\Firebird Project\Firebird Server\Instances is used to locate the Firebird installation directory and the underlying "bin" directory is searched for the FB Client DLL. iv. The Default installation directories C:\Program Files\Firebird\Firebird_2_x are searched for the FB Client DLL. v. The PATH Environment variable is used to search for the FB Client DLL. vi. Finally the PATH Environment variable is used to search for IBASE.DLL. 3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine. See doc/readme.scriptengine and example applications. 4. New Component: TIBlocalDBSupport. This is a TIBDatabase support component intended to simplify the use of the embedded firebird server on both Linux and Windows platforms. See dpc/readme.localdatabase and example applications. 5. IBDynamicGrid: Reordering on column header click should now also work for dynamic columns. 6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition between incrementing/decrementing the lock count and signalling the event. IBX Change Log version (1.3-2) Tue, 26 Jan 2016 14:39:54 +0000 1.3.2 was never formally released and only made available as beta copies. 1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo 2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column 3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early 4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset i.e. when it is a calculated field 5. IBDynamicGrid: Fix problem selecting a different row when expanded row at end of grid. This problem was due to a race condition between recalculating row heights and determining which row was selected by the mouse click. The row height calculation is now deferred by an extra trip round the message loop allowing the row to be always calculated on the current grid layout rather than risking it being calculated on the grid layout after the expanded row has been shrunk. 6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on Windows. 7. TIBStringField: Now has two new public properties: CharacterSetName: string and CharacterSetSize: integer; These properties allow the (Firebird) character set name for the field and the max number of bytes per character to be determined at runtime. See doc/readme.charactersets.html. 8. TIBWideStringField: This is a new field type with the same additional public properties as above and subclassed from TWideStringField. This field type is used with the character size reported by Firebird is two. See doc/readme.charactersets.html. 9. TIBMemoField and TIBWideMemoField: new field types with the same additional public properties as above and subclassed from TMemoField and TWideMemoField respectively. These field types are used with Blob subtype 1 and a characterset size of 1, 3 or 4 (TIBMemoField) or 2 (TIBWideMemoField). See doc/readme.charactersets.html. Both also have a new published property "DisplayTextAsClassName". If false (default) the displaytext is generated from the blob text by truncating the string to the displaywidth (in characters not bytes). A displaywidth of zero implies no truncation. 10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active. 11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state (avoids "Not in Edit Mode" error). 12. IBDynamicGrid: Correctly resize grid when one column width plus indicator. 13. IBDynamicGrid: Ensure Editor Panel has focus when shown - avoids Windows API calling DBGrid.DoExit on subsequent mouse click (e.g. on child control such as a tabbed page control. 14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent. 15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls 16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked. 17. IBCustomDataSet: On close, parser is now freed and Select SQL reverts to value before DataSet Opened. IBX Change Log version (1.3-1) Sat, 18 Jul 2015 13:30:50 +0100 1. OnCloseUp Event Handler added to TDBLookupProperties 2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids problem with row size when exception is called. 3. IBLookupComboEditBox: Force pending autocomplete on combobox exit. 4. IBDynamicGrid and DBControlGrid: Keyhandler now ignores up, down, escape and return keys if in a TCustomComboBox and ignores return key if in a TCustomMemo 5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text keyed in i.e. when autocomplete not performed 6. Cleanup of "Uses" clauses and add console mode support. IBX should now support console mode applications with all LCL required functions (builtin dialogs and cursor management) centralised in the IBDialogs unit. As long as "IBDialogs" is not included in your project, IBX should compile and link with a console mode program. See consolemode example and its "readme"for further guidence. DO NOT add the ibexpress package to a console mode application or the IDE will automatically assume that your application is GUI based. Instead, you should include the ibexpressconsolemode package. IMPORTANT NOTE: IBDialogs must be included in GUI applications in order to use the built in dialogs and cursor management. IBDialogs is included by default if "ibexpress" is in your project source's "uses" clause. This should be the case for all projects created through the IDE. This is why you do not want to add the ibexpress package to console mode applications. The ibexpressconsolemode package has been created to allow console mode programs to avoid adding LCL dependencies when using IBX, while still having the unit search paths set up correctly. Existing users should check to ensure that the "ibexpress" unit is included in each project's source file (*.lpr). You may find that in order for the IDE to recognise that ibexpressconsolemode exists, you have to first open the package in the IDE and then close it. This adds it to the most recently accessed packages list. To make it permanently available, add the package name to lazarus' staticpackages.inc file. Thanks to Julio Jiménez for suggesting support of console mode. 7. SQL Parser can now accept quoted strings that include new lines 8. IBDynamicGrid: Lookup Cell Editor - the cursor is now positioned at end of text on start of edit. This is particularly useful when tabbing to a column and then inserting text. 9. New Examples provided for IB Services and ISQLMonitor. 10. Fix error when writing to blob streams that recorded only the last buffer write in the blob stream. In most cases, this did not cause a problem as the IB Blob Stream is written in a single write. However, with the TDBImage, write of a graphic type prefix was lost which caused a problem when the image could not be automatically recognised. 11. Improve generation of random cursor names in TIBSQL - avoid risk of "cursor already open" errors due to random numbers used for the cursor name being identical. 12. IBTable: corrected error that could result in an "Index out of bounds" error when opening the table and the Primary Key is the last or only column in the table. Thanks to Rick Hoover for the fix. 13. Fix TIBDatabase initialisation of lc_ctype under unix. Set to "UTF8" instead of "UTF-8", and update list of available database character sets. Existing users should check the current lc_ctype setting in their applications. IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100 1. Firebird Services: avoid List Index error when opening a service with an empty Params property. 2. IBControls: Fix problem with new link mechanism introduced in 1.2.3. Link now set up in Loaded method - avoids occasional failure to apply SQL markup on initial open. 3. "Employees" example performance improvements when scrolling. 4. DBControlGrid: Correctly handle edit panel removal when panel is child control of a TFrame. Force recaching of selected frame to avoid GTK race (results in a random image cached). 5. DBControlGrid: Should now react to changes in panel height at run time. 6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid even when further rows exist. 7. DBControlGrid: DefaultRowHeight is no longer a published property as it should always be derived from panel height and setting this property can cause confusion. Note for existing projects: to avoid a missing property error at run time, each form using the DBControlGrid must be opened, updated and saved in the IDE in order to remove the property value from the lfm. IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100 1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always call Prepare before setting parameter values. 2. Error message on ParamByName (all cases) not found now includes name of missing parameter. 3. Code tidyup and more robust handling of dsql information result vector. 4. Support for centralised handling of transaction status changes. TIBTransaction has been given additional events "AfterEdit", "AfterInsert", "AfterDelete", "AfterPost" and "AfterExecQuery". The first three are called after the same event is called for an IBCustomDataSet descendent using the Transaction. The fourth is called after a call to TIBSQL.ExecQuery, again using this transaction. These new events enable monitoring of transaction status changes for a given transaction to be handled in a single place. For example, when a change to the dataset occurs an indicator can be set that shows the user that in order to save changes, the transaction should be committed. Rather than doing this per dataset, this can now be done per transaction. 5. TDataSet.CheckBrowseMode automatically posts changes to the current row when the dataset is scrolled. However, any changes to the current row are, by default, discarded when the dataset is closed. TIBDataSet, TIBQuery and TIBTable now have a new property "DataSetCloseAction" that adds automatic posting of changes on dataset close. If this property is set to dcDiscardChanges (default) then the behaviour is unchanged from previous versions. if the value is set to dcSaveChanges then IBX will attempt to post any unsaved changes before the dataset is closed (and after the BeforeClose event handler is called). The exception is when the dataset is being closed as a result of a transaction rollback. In this case, no action is taken and any unsaved changes are discarded. This avoids both unnecessary overhead and the risk that a validation error may occur in the Post raising an exception and thereby preventing a rollback. 6. String Field sizes and Display Widths should now be correct for multi-byte character sets. In earlier versions, the Display Width was set to the maximum byte width rather than the character width. Display Widths are now corrected by dividing by the max byte width per character. For UTF8 character sets, the byte width is four and hence the Display Width will be the byte width divided by 4. The byte width of each character set is determined dynamically when the database connection is estabished from the RDB$CHARACTER_SETS system table. (see also http://bugs.freepascal.org/view.php?id=27766). 7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string. 8. IBLookupComboEditBox: List should now always be restored to full list when the control loses focus. Default Key press default interval reduced to 200ms. 9. DBControlGrid: Ensure that selection is changed to newly appended row, even when dataset rows are less than visible rows. 10. IBDynamicGrid: Editor Panel is not shown on indicator click if Datasource does not exist or DataSet is empty. More responsive on dataset open. New event OnRestorePosition. Column sort disabled if no header row. 11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset while dataset state is dsInsert. Avoids posting errors. 12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to avoid conflict with DisableControls/EnableControls with Master/Detail linked tables. 13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes. 14. TIBDataSet and TIBQuery: new Event - OnValidatePost. This event has been introduced to solve a specific problem. That is when the dataset cursor is moved (e.g. by a grid mouse click and the current row is being edited or inserted. In this case, TDataset always "posts" the current record regardless or whether or not it may be more appropriate to cancel any changes; the post occurs before the "BeforeScroll" event fires due to the way the "MoveBy" function is implemented by TDataSet. The OnValidatePost event is called as the first action of the "Post" method and allows the handler to convert the Post into a Cancel if that is the appropriate action on moving to a different row. This is achieved by returning with "CancelPost" argument set to true. Note that an exception could be raised here, but it may still be more appropriate to validate a post and signal a problem in the "BeforePost" event handler. See readme.automaticposts.xhtml) 15. On Unix derived systems, the Firebird library name can now be given as a colon separated list. Each library name on the list is tried in turn, in left to right order with the first found being used as the firebird library. By default, on Linux, the library name list is 'libfbembed.so.2.5:libfbembed.so.2.1:libfbclient.so.2'. This can be overidden by the FBLIB environment variable or the OnGetLibraryName function. Note: when using the libfbembed.so, if you prefix the database name with "localhost:" then it will still attempt to access the database via the Firebird Server and will require a username and password. If only the pathname is given, then the username and password should be omitted and the unix file permissions are used to grant access. IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000 1. A new IBControl - TDBControlGrid has been added. TDBControlGrid a lookalike rather than a clone for the Delphi TDBCrtlGrid. TDBControlGrid is a single column grid that replicates a TWinControl - typically a TPanel or a TFrame in each row. Each row corresponds to a row of the linked DataSource. Any data aware control on the replicated (e.g.) TPanel will then appear to have the appropriate value for the row. 2. As suggested by Julio Jiménez, a new property "SQLHourGlass" has been added to TIBDatabase. When set to false (default true), the Hour Glass cursor is supcpressed and no cursor change takes place during database access. This may be useful when there are performance issues with the change of cursor. Setting the property to false suppresses the change of cursor. 3. As suggested by Julio Jiménez, a new property "AutoCommit" has been added to TIBDataSet, TIBQuery and TIBTable. When set to acCommitRetaining (Default: acDisabled), a call is made to Transaction.CommitRetaining immediately after every Post or Delete. This has the effect of making all changes permanent immediately rather than when the transaction is explicitly committed. 4. Experimental support for the Firebird 3 SQL_BOOLEAN type has been added while still using the legacy Firebird API. Thanks to Gabor Boros for helping to test this feature. IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000 Development version only. IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000 1. An internal select SQL Parser is now available for TIBCustomDataset descendents. This is typically used during an "OnBeforeOpen" event handler to manipulate the "Where" and "Having" clauses to implement user specified filters of arbitrary complexity. 2. A new Component Palette entry "Firebird Data Controls" is now available. This has three new data aware controls dependent on IBX and which make use of the SQL Parser. These are: - TIBLookupComboEditBox - TIBDynamicGrid - TIBTreeview TIBLookupComboEditBox is a TDBLookupComboBox descendent that implements "autocomplete" of typed in text and "autoinsert" of new entries. Autocomplete uses SQL manipulation to revise the available list and restrict it to items that are prefixed by the typed text (either case sensitive or case insensitive). Autoinsert allows a newly typed entry to be added to the list dataset and included in the available list items. TIBDynamicGrid is a TDBGrid descendent that provides for: - automatic resizing of selected columns to fill the available row length - automatic positioning and sizing of a "totals" control, typically at the column footer, on a per column basis. - DataSet resorting on header row click, sorting the dataset by the selected column. A second click on the same header cell reversed the sort order. - Support for a "Panel Editor". That is on clicking the indicator column, the row is automatically expanded and a panel superimposed on it. The panel can have any number of child controls, typically data aware controls with the same datasource as the grid allowing for editing of additional fields and more complex editors. - Reselection of the same row following resorting. - A new cell editor that provides the same functionality as TIBLookupComboEditBox. Its properties are specified on a per column basis and allows for one or more columns to have their values selected from a list provided by a dataset. Autocomplete and autoinsert are also available. The existing picklist editor is unaffected by the extension. TIBTreeView is a data aware TCustomTreeView. 3. When getting a field value using FieldByName.AsVariant, an SQL_INT64 with a zero scale will no longer return an error. An Int64 will be returned instead. 4. TIBTransaction now has events for Before and After Transaction End and a new function "GetEndAction" allowing the EndAction to be accessed by these event handlers. 5. TIBQuery can now handle correctly queries which contain the same keyword parameter repeated multiple times. 6. TIBUpdateSQL will no longer return an error when "RowsAffected" is <> 1. This error check used to get in the way of using Stored Procedures, and "Update or Insert" statements. 7. Insert, Modify and Delete property Editors now support Query Generation from Stored Procedures. 8. Three new examples illustrate the use of the new IB Controls IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100 1. TIBXSQLVAR code clean up and optimisation to improve client side "prepare" and parameter setting performance. See "readme.field+param.names in the doc folder.(Thanks to Gabor Boros for reporting this problem and for testing the improvements). 2. IBX can now support dialect 3 quoted column names that contain spaces and which differ only in their case. See readme.field+param.names in the doc folder. 3. IBX SQL Editors will now automatically add double quotes around column names when the database dialect is "3" and the column name contains spaces or is a Firebird 2.5 SQL Reserved Word. 4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc 5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once" actions. 6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with thanks to Yuriy Kopnin for pointing this out). 7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet. 8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types for both fields and parameter setting. 9. Changes to the Select SQL in an IBCustomDataset descendent should now be visible in the Fields Editor immediately afterwards - rather than only after cycling the "active" property. 10. TIBSQL SQL editor will operate correctly and not report an SQL syntax error on SQL test, when DSQL ('?') parameter placeholders are used and the TIBSQL.GenerateParamNames property is set to true. 11. TIBTable now has a property editor for "MasterFields" 12. SQL Property Editors now include a checkbox "Allow DSQL Placeholder". This corresponds to the GenerateParamNames property and should be set when using DSQL (i.e. '?') style parameters. 13. The IBTransaction editor now has a radio button ("Unspecified") which is set when the combination of settings is unrecognised. Selecting this radio button has no effect on the settings. IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000 1. TBookmark change conditional compile changed to >= 2.7.0 to match revised availability of change. IBX Change Log version (1.0-4) Thu, 28 Feb 2013 16:56:13 +0000 1. In a TIBCustomDataset descendent, a generator now only sets the value when it is null. This allows for alternative user defined setting of the generator Many thanks to Julio Jiménez for this fix 2. An Error Dialog is now displayed in the Lazarus IDE if IBX cannot find the Firebird Library and suggests that the user may have forgotten to install it. IBX Change Log version (1.0-3) Thu, 22 Nov 2012 22:53:39 +0000 1. Conditional compilation used to limit registration of TIntegerField to Lazarus versions less than 1.1 2. When a database connection is created, character set is now by default set to UTF8 (Unix) or to the current Windows code page (Windows) if in the range 1250 to 1254. IBX Change Log version (1.0-2) Tue, 09 Oct 2012 09:10:30 +0100 1. TBookmark change conditional compile changed to > 2.6.2 to match expected availability of change. IBX Change Log version (1.0-1) Sun, 05 Aug 2012 20:00:04 +0100 1. In IBCustomDataset. Changed CurBookmark from string to TBookmark for compiler versions > 2.6.0 Necessary because of TBookmark type and TDataSet.Bookmark property change in fpc 2.7.1 2. IBX now registers TIntegerField as a "No Icon" component. This may be removed if the fpc DB package is changed to do this (which it should do). IBX Change Log version (1.0-0) Sat, 28 Apr 2012 16:43:00 +0100 1. Add "if active then active := false" to TIBCustomDataset destructor. (Avoid error on database close). 2. Make use of $STATIC conditional in IBSQLMonitor (Needed for FPC 2.6.0 compliance) 3. Database Property Editor: Character Set drop down box now uses "OnChange" rather than "OnCloseUp" to react to changes 4. Property editors should now correctly resize. 5. In IBDatabaseEdit.TestClick, the LoginPrompt is now set to the state of the LoginPrompt Checkbox (restored original functionality) 6. Under OSX, if IBX fails to load libfbclient.dylib, it will now try and load the firebird library using the absolute path /Library/Frameworks/Firebird.framework/Firebird.
