+FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
-+
-+
+. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
-+
-+
+. Remove constraint in IAttachment.HasScollableCursors that returned false when
-+
+   using remote protocol. Scrollable cursors with remote database expected to
-+
+   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
-+
+   a not supported error.
-+
-+
+. IStatement: new function;
-+
+    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
-+
+    TStatementFlags = set of TStatementFlag;
-+
+    function GetFlags: TStatementFlags;
-+
-+
+. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
-+
+   compatibility.
-+
+   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
-+
+   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
-+
+   to be used with Update...Retruning statements that return a singleton row,
-+
+   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
-+
+   it will open the cursor and return the first row only.
-+
-+
+. ITransaction: new functions:
-+
+    function GetIsReadOnly: boolean;
-+
+    function GetTransactionID: integer;
-+
+    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
-+
+    function GetTrInformation(Request: byte): ITrInformation; overload;
-+
-+
+   The latter two return the Transaction Information block. The first two extract
-+
+   information the Transaction Information block
-+
-+
+. New function TSQLTokeniser.ReadCharacters
-+
+   Used internally.
-+
-+
+. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
-+
+   parameter placeholders instead of named parameters.
-+
-+
+. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
-+
+   transaction handle is now ignored if Rollback/Commit is called with Force=true
-+
-+
+FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
-+
-+
+. TFBClientAPI.GetProcAddr. Add check for nil reference.
-+
-+
+. IStatement: new methods:
-+
+    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
-+
+    function GetStaleReferenceChecks: boolean;
-+
-+
+   In previous versions, stale reference checks were always enabled. This allows the
-+
+   user to disable them on a per statement basis. Note this can risk out-of-date
-+
+   statement BLR. See User Guide.
-+
-+
+. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
-+
+   stored procedure and hence avoids replacing named parameters within a containing
-+
+   BEGIN..END block.
-+
-+
+. ISQLParam: using a string value to set an integer field with a scale factor of
-+
+   zero is now treated as a special case to avoid the risk of floating point
-+
+   rounding errors affecting pure integers.
-+
-+
+. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
-+
-+
+. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
-+
+   SQL Parameter metadata (methods moved from ISQLParam).
-+
-+
+. ISQLParam: new method
-+
+     function getColMetadata: IParamMetaData;
-+
+   This instance of IParamMetaData returns the original column metadata which is unmutable.
-+
+   Note: ISQLParam metadata can change after a parameter value has been set e.g when
-+
+   setting a VARCHAR column to an integer value.
-+
-+
+. IStatement: can now set cursor name when opening a cursor. New overloaded method:
-+
+    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
-+
+   also IAttachment:
-+
+    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
-+
+    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
-+
+    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
-+
+                       aSQLDialect: integer; GenerateParamNames: boolean=false;
-+
+                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
-+
+    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
-+
+                       GenerateParamNames: boolean=false;
-+
+                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
-+
-+
+. Support for scrollable cursors added. New/updated methods:
-+
+   IAttachment:
-+
+    function HasScollableCursors: boolean;
-+
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
-+
+                             Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
-+
+                             params: array of const): IResultSet; overload;
-+
+    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
-+
+                             params: array of const): IResultSet; overload;
-+
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
-+
+                             params: array of const): IResultSet; overload;
-+
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
-+
+                             Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
-+
+                             params: array of const): IResultSet; overload;
-+
+    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
-+
+    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
-+
+                             params: array of const): IResultSet; overload;
-+
+   IStatement:
-+
+     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
-+
+   IResultSet:
-+
+    function FetchPrior: boolean; {fetch previous record}
-+
+    function FetchFirst:boolean; {fetch first record}
-+
+    function FetchLast: boolean; {fetch last record}
-+
+    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
-+
+    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
-+
+    function IsBof: boolean;
-+
-+
+. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
-+
-+
+. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
-+
+    may be noticeable when a line separator occurs inside quoted text. The quoted text
-+
+    output by the tokeniser will now use the platform specific lineEnding regardless
-+
+    of whether the input uses the CRLF or LF as a line separator.
-+
-+
+. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
-+
-+
-+
+FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
-+
-+
+. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
-+
-+
+. Support for inline blob encoding. Blob values pass using the "SetAsString" method
-+
+   will now be encoded inline (i.e. as part of the parameter buffer) if they are
-+
+   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
-+
+   separate server interaction. This is intended as a performance optimisation.
-+
-+
+   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
-+
+   IAttachment interface functions:
-+
-+
+    function GetInlineBlobLimit: integer;
-+
+    procedure SetInlineBlobLimit(limit: integer);
-+
-+
+. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
-+
+   user as the functionality is embedded in the implementation of the IStatement
-+
+   interface. Three new functions are defined:
-+
-+
+    procedure AddToBatch;
-+
+    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
-+
+    procedure CancelBatch;
-+
+    function GetBatchCompletion: IBatchCompletion;
-+
+    function GetBatchRowLimit: integer;
-+
+    procedure SetBatchRowLimit(aLimit: integer);
-+
-+
+   Also
-+
-+
+    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
-+
+    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
-+
-+
+   For more information see the User Guide.
-+
-+
+. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
-+
+   provided with the EIBInterBaseError now include all three parts.
-+
-+
+. Firebird.pas and include files updated to Firebird 4.0.0
-+
-+
+. New IStatement method: function GetSQLStatementTypeName: AnsiString;
-+
+   Returns SQL Statement type as a text string;
-+
-+
+. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
-+
+   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
-+
-+
+FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
-+
-+
+. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
-+
+   typo in FB30Statement.pas that caused an unknown parameter error.
-+
+FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
+. Imported (Firebird) constants updated for Firebird 4.
