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. +1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API + with a Firebrid 3 client library. -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. +2. Linux Only: FIREBIRD environment variable is now checked when loading the client library. + If a client library path is not explicitly provided and the FIREBIRD environment + variable is set then the directory given by this variable and any 'lib' subdirectory + are searched for the Firebird client library. Only if none is found, is the default + client library used. -3. New Component: TIBXScript. This is an ISQL compatible SQL script execution engine. - See doc/readme.scriptengine and example applications. +3. IUtil.FormatStatus now used to format error messages when using new API -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. +4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer. -5. IBDynamicGrid: Reordering on column header click should now also work for - dynamic columns. +5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is + returned using GetAsString and the string codepage is UTF8, the string is truncated so + that the byte length corresponds to the number of characters specified for the column. + SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is + correct behaviour but may affect some implementations that relied upon automatic + trimming of trailing white space. -6. ISQLMonitor: (Windows only). Mutex added to TMultilockGate to avoid race condition - between incrementing/decrementing the lock count and signalling the event. +6. New IFirebirdAPI Calls: + function GetClientMajor: integer; + function GetClientMinor: integer; -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. +FBINTF Change Log version (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100 -1. DBControlGrid,IBDynamicGrid: Ignore down arrow and up arrow in TCustomMemo +1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are + case sensitive -2. IBDynamicGrid: Now deals correctly with a single column grid which has no indicator and autosize column +2. Single line SQL comments starting with '--' are now recognised by SQL Parser. -3. IBLookupComboEditBox: reset timer on each key press - avoids timer going off too early +3. New API Calls: + IColumnMetaData.GetStatement + IColumnMetaData.GetTransaction + ISQLData.GetStrLength + IResults.GetStatement + IAttachment.OpenBlob (using Blob metadata) + IAttachment.OpenArray (using array metadata) -4. IBDynamicGrid: Call event OnUpdateSortOrder even when aliasname not found in dataset - i.e. when it is a calculated field +4. FBMessages: removal of unused messages -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. +5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set. -6. IBLookupComboEditBox: avoid race condition between cm_killfocus and cm_exit on - Windows. +6. TIBSQLStatementType: SQLSavePoint added to end of enumeration. -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. +FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000 -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. +1. Fix a problem with the SQL parameter parser that failed to recognise parameters + where the second character of the parameter name is a numeric. -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. +2. New method for IAttachment: procedure getFBVersion(version: TStrings); + This returns the isc_version connection information as one or more lines. + This is the same information as returned by isql with the -z option. - 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. +3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API + is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a + compiler option then the Firebird 3 API is no longer compiled in. -10. IBLookupComboEditBox: Force autocomplete when EditingDone called and timer active. +4. IColumnMetaData: new method. -11. IBDynamicGrid: Call DataSet.Append when entering edit mode and dataset empty and not in insert state - (avoids "Not in Edit Mode" error). + TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP} + dfDateTime, {SQL DATETIME} + dfTime); -12. IBDynamicGrid: Correctly resize grid when one column width plus indicator. + function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer; -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. + This returns the max. number of characters returned by the "AsString" method + when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME. -14. IBDynamicGrid: ignore up, down tab and return when editorpanel open and focus in a TCustomGrid descendent. +5. Additional argument for IAttachment.PrepareWithNamedParameters - + CaseSensitiveParams: boolean = false -15. DBControlGrid: Stop flashing grid when dataset closed and then re-opened while DisabledControls + If this argument is set to true then SQL parameter names are assumed to be case + sensitive and must be referenced (using ISQLParams.ByName) using the case + sensitive name. -16. IBQuery: Bug fixed that prevented SQL being set programmatically once the Parser had been invoked. +6. Bug fix: when setting a query parameter, it is now possible, when the parameter + is of type VarChar or Char to set the parameter to a numeric value (e.g. using + .AsCurrency) and then subsequently to update the value to a non-numeric string + using .AsString. -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 +FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000 -2. IBDynamicGrid: Call to OnEditorPanelHide is now last editor hide action - avoids - problem with row size when exception is called. +1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary -3. IBLookupComboEditBox: Force pending autocomplete on combobox exit. +2. Restrict IsMultiThread check to Unix only for compatibility with + https://bugs.freepascal.org/view.php?id=30535 -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 +3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with + named parameters and is intended to avoid problems with (e.g.) Execute Block + and processing internal parameters as statement parameters. -5. IBLookupComboEditBox: Ensure that KeyValue is set correctly when full text - keyed in i.e. when autocomplete not performed +4. New interface IFirebirdLibrary provides access to the underlying firebird DLL + or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI. -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. +5. New function added to IB.pas - 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. + function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary - Existing users should check to ensure that the "ibexpress" unit is included in - each project's source file (*.lpr). + This allows a Firebird Library to be loaded from an explicit path. use the + IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using + the library. It is possible to load Firebird libraries from different locations + simultaneously, each with a distinct IFirebirdAPI. - 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. +FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100 - Thanks to Julio Jiménez for suggesting support of console mode. +1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when + program compiled with -CR command line switch. -7. SQL Parser can now accept quoted strings that include new lines +2. IServiceManager additions (informational): + function getProtocol: TProtocol; + function getPortNo: AnsiString; -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. +3. IServiceManager improved error handling. Interfaces changed: + function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean; + function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; + function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; -9. New Examples provided for IB Services and ISQLMonitor. +4. IAttachment addition (informational) + function GetSecurityDatabase: AnsiString; -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. +5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics + thus now returns accumulated stats for a select statement from opening a cursor + up to the last fetch. -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. +6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting + the problem. -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. +7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64" + replaces deprecated "comp" type. -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. +10. Testsuite Test10 updated to include thread synchronisation for event reporting. -IBX Change Log version (1.2-4) Sat, 09 May 2015 12:38:29 +0100 +11. URL Connection Strings: inet4 and inet6 now recognised. -1. Firebird Services: avoid List Index error when opening a service with an - empty Params property. +12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax. -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. +13. IAttachment.CharSetName2CharSetID is now performed case insensitive. -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). +FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000 -5. DBControlGrid: Should now react to changes in panel height at run time. +1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character. -6. IBDynamicGrid: Redraws rows below on panel editor hide - avoids blank space at end of grid - even when further rows exist. +2. IAttachment: add two new methods + function HasDefaultCharSet: boolean; + function GetDefaultCharSetID: integer; -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. + These return, respectively, true if a connection default character set was + specified and the character set id of the connection default character set. + The DefaultCharSetID is cached when the connection is opened and hence does not + require a database lookup. +3. Avoid exception when a text blob is a stored procedure parameter. -IBX Change Log version (1.2-3) Tue, 14 Apr 2015 14:11:17 +0100 +4. Update test suite to include a test for a stored proc returning a text blob. -1. TIBStoredProc. Prepare now called by ParamByName to avoid need to always - call Prepare before setting parameter values. +5. IAttachment: add + function GetRemoteProtocol: AnsiString; + function GetODSMajorVersion: integer; + function GetODSMinorVersion: integer; + function GetAuthenticationMethod: AnsiString; -2. Error message on ParamByName (all cases) not found now includes name of missing parameter. + These results are cached when the connection is opened and hence do not + require a database lookup. -3. Code tidyup and more robust handling of dsql information result vector. +6. IAttachment: add "function GetConnectString: AnsiString;" This returns the + connect string used to create/connect to the database. -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. +7. IAttachment: Create Database using SQL statement. The username and password + are now extracted and used to populate a DPB made available via IAttachment.getDPB. + It is now possible to use IAttachment disconnect/connect to reconnect to + a database for which the initial connection was established by a create + database sql statement. Available in FPC only. -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. +8. Update Test 1 to test 5, 6 and 7 above. -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). +9. IBUtils code tidy up. -7. SQLParser will now correctly parse SQL Text which contains ':' within quoted string. +10. Parameter Block interfaces "find" method. As documented, this should have + returned a nil interface when the item could not be found. Instead, an empty + interface item was returned. "Find" now works as documented and will return + a nil interface if the item cannot be found. -8. IBLookupComboEditBox: List should now always be restored to full list when the - control loses focus. Default Key press default interval reduced to 200ms. +11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date. -9. DBControlGrid: Ensure that selection is changed to newly appended row, even - when dataset rows are less than visible rows. +12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information + requests with additional parameters. This is to enable support for fb_info_page_contents + (return of page contents). Response to fb_info_page_contents returned as + a string with code page CP_NONE. -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. +13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus + test suite updated. -11. IBTreeView: improved handling of response to "Add Node". Avoid scrolling dataset - while dataset state is dsInsert. Avoids posting errors. +14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as + a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type. -12. IBControls: New mechanism for distributing UpdateSQL and UpdateParams events. This is to - avoid conflict with DisableControls/EnableControls with Master/Detail linked tables. +15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet. + An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non + default connection port to be specified. -13. IBLookupComboEditBox: Now avoids SQL Errors when combo box text contains single quotes. +FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000 -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) +1. Fix issues with setting SQL Param values using SetAsString with Numeric types. + Scale is no longer ignored. -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. +2. Fix issues with setting SQL Param values using SetAsString with Date values + not in locale format but which are recognised by Firebird. Date values that + cannot be converted to a string using Pascal library are now passed through + to Firebird as Text Strings. - 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. +3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns + UTF8 and not UNICODE_FSS. -IBX Change Log version (1.2-2) Sat, 14 Mar 2015 11:35:04 +0000 +4. Charset ID problem. When using Firebird 3, with no default database character set + and a column has a non-default collation specified, an incorrect character set + id was being reported that could result in a 'division by zero' error when + used by IBX. This has now been fixed. -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. +5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID, + CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as + the character sets supported can be updated on a per database basis. That is + it is possible to add a (Firebird) user defined character set to a database. -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. +6. Add RegisterCharSet to IAttachment. This is used to register a user defined character + set supported by Firebird with the API. -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. +7. Add missing isc_info_db_read_only to list of decoded Database Information items + in FBOutputBlock.pas and update test suite to include this item. -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. +8. FB30Client: avoid always using "StartMultiple" when only a single database attachment. -IBX Change Log version (1.2-1) Fri, 13 Mar 2015 11:14:15 +0000 +9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client + library or finding it by disk location, the PATH environment variable is now also set to + include the FIREBIRD directory. This is to ensure that the correct dlls in the + firebird client library dependencies are loaded. -Development version only. +10. Testsuite: Ensure consistent UTF-8 output on Windows console. -IBX Change Log version (1.2-0) Thu, 26 Feb 2015 10:34:04 +0000 +11. Testsuite: Update Windows script to include FPC 3.0.4 in search path. -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. +12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer -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: +13. FB30Statement: A check has been added to ensure that all SQL Parameters + have been given a value (including NULL). Previously, failing to set the + value of an SQL Parameter could give rise to unpredictable results or + an SQLDA error. - - TIBLookupComboEditBox - - TIBDynamicGrid - - TIBTreeview +14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set. - 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. +15. FBAttachment: Avoid string reference count error when processing an Ansistring + parameter in an array of const passed to IAttachment.OpenCursor, etc. - 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. +16. FBAttachment: Allow for WideString and UnicodeString parameters in an array + of const passed to IAttachment.OpenCursor, etc. - 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. +FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000 -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. +1. Change syntax to Mode Delphi -5. TIBQuery can now handle correctly queries which contain the same keyword parameter - repeated multiple times. +2. Change all uses of string type to explicit AnsiString in order to ensure + compatibility between Delphi and FPC. -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. +3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs + defined for each interface. -7. Insert, Modify and Delete property Editors now support Query Generation from - Stored Procedures. +4. Generics syntax variations for Delphi added -8. Three new examples illustrate the use of the new IB Controls +5. PChar replaced with PByte expect where an actual string is being referenced, + where PAnsiChar is used instead. +6. Review of type definitions in IBExternals to ensure Delphi compatibility -IBX Change Log version (1.1-0) Mon, 07 Jul 2014 14:01:07 +0100 +7. Testsuite updated for Delphi -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). +FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000 -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. +1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with + large blobs and the FB3 API. -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. +2. Update Event Handling algorithm to avoid looping due to recreation of the + event block. -4. Param Type LargeInt now supported in TIBQuery and TIBStoredProc +3. Avoid invalid XSQLDA error when the only parameter is updated to null -5. TIBSQL.ExecQuery retry on failure removed to avoid problems with "at most once" - actions. +4. Array Handling: fix problem with text arrays with character set none. When the + DB connection has a default character set (e.g. UTF8), an error is raised by + Firebird if the space allocated is not enough to allow for transliteration, even + though it is not required for character set none. -6. TIBTransaction.SetDefaultDatabase uses SetObjectProp instead of mis-using SetOrdProp (with - thanks to Yuriy Kopnin for pointing this out). +5. IBUtils: List of reserved words brought up-to-date -7. GenerateParamName is now a published property of TIBSQL, TIBQuery and TIBDataSet. +6. Add ISQL style performance statistics collection to IStatement -8. varWord, varShortInt and varInt64 added to TIBXSQLVAR.SetAsVariant and hence now available as variant types - for both fields and parameter setting. +7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided + CREATE DATABASE statement. -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. +8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in + an array dimension is not mistaken for a named parameter prefix. -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. +9. Trim function no longer applied to result of GetAsString for SQL_TEXT + when Character set is octets. Avoids loss of non printable characters at start of string. -11. TIBTable now has a property editor for "MasterFields" +10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance + statistics for the last action. Requires use of procedure IStatement.EnableStatistics + to enable stats gathering. -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. +11. API Version information added as constants to IB.pas -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. - +12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID -IBX Change Log version (1.0-5) Sat, 28 Dec 2013 19:22:23 +0000 +13.

Initial Release -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.

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.
