+FBINTF Change Log  version          (1.4-1 Build 14019) Sat, 05 Aug 2023 13:21:51 +0100
-+
-+
+. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error
-+
+   checks for range checking.
-+
-+
+FBINTF Change Log  version          (1.4-0 Build 14011) Sat, 05 Aug 2023 11:09:09 +0100
-+
-+
+. Support package fbudr added for support of User Defined Routines (UDRs), and package
-+
+   fbudrtestbed for client side debugging of UDR libraries.
-+
-+
+. Package layout changed with introduction of udr support. IB*.pas files moved from
-+
+    root directory to "client". IBHeader moved to "Client".
-+
-+
+. Delphi packages: all packages now compile .dcp and .bpi files to either
-+
+   fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing
-+
+   fbintf.dcp and fbintf.bpi files from other locations.
-+
-+
+. Client side journaling support added. Interface changes
-+
+   IAttachment
-+
+    function JournalingActive: boolean;
-+
+    function GetJournalOptions: TJournalOptions;
-+
+    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
-+
+    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
-+
+    function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
-+
+    procedure StopJournaling(RetainJournal: boolean);
-+
-+
+. Transactions may now be given a local transaction name:
-+
+   IFirebirdAPI
-+
+     function StartTransaction(Attachments: array of IAttachment;
-+
+             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
-+
+             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
-+
+             aName: AnsiString=''): ITransaction; overload;
-+
+     function StartTransaction(Attachments: array of IAttachment;
-+
+             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
-+
+             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
-+
+             aName: AnsiString=''): ITransaction; overload;
-+
-+
+   IAttachment
-+
+    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
-+
+    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
-+
+    function StartTransaction(TPB: array of byte;
-+
+                              DefaultCompletion: TTransactionCompletion=taCommit;
-+
+                              aName: AnsiString=''): ITransaction; overload;
-+
+    function StartTransaction(TPB: ITPB;
-+
+                              DefaultCompletion: TTransactionCompletion=taCommit;
-+
+                              aName: AnsiString=''): ITransaction; overload;
-+
-+
+  ITransaction
-+
+    function GetTransactionName: AnsiString;
-+
+    procedure SetTransactionName(aValue: AnsiString);
-+
-+
+. Additional Transaction information
-+
+     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
-+
-+
+   ITransaction
-+
+     function GetDefaultCompletion: TTransactionCompletion;
-+
+     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
-+
-+
+. New IAttachment helper functions
-+
+     function HasTable(aTableName: AnsiString): boolean;
-+
+     function HasFunction(aFunctionName: AnsiString): boolean;
-+
+     function HasProcedure(aProcName: AnsiString): boolean;
-+
+     function GetAttachmentID: integer;
-+
+     function GetCharSetID: integer;
-+
-+
+. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
-+
+   will be allocated for batch operations.
-+
-+
+. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
-+
+    function GetStatement: IStatement;
-+
+    function GetTransaction: ITransaction;
-+
+    function GetAttachment: IAttachment;
-+
-+
+. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
-+
+    interfaces.
-+
-+
+. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
-+
+    and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
-+
+    functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
-+
+    of numerics without loss of precision.
-+
-+
+. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
-+
-+
+. ISQLParams new method "Clear"
-+
-+
+. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
-+
+    request rather than on attachment connect.
-+
-+
+. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the
-+
+    fact that SQLCodes are soon to be deprecated. In the future, the other options
-+
+    will be silently ignored if SQLCode support is not present in the Firebird
-+
+    Client library.
-+
-+
+. ITransaction changes Rollback and Commit from procedures to functions:
-+
+      function Commit(Force: boolean=false): TTrCompletionState;
-+
+      function Rollback(Force: boolean=false): TTrCompletionState;
-+
-+
+    Specifically, this is to allow the functions to report back a failed commit or
-+
+    rollback when Force = true. In the case, the transaction handle has been
-+
+    released, while the transaction remains in limbo.
-+
-+
+. IAttachment ExecImmediate.
-+
+    When the transaction parameters are provided as an array of const and the
-+
+    statement fails, the transaction is rolledback (forced) before the exception
-+
+    is raised.
-+
-+
+. In Firebird 3 and later API: the status vector is now a thread var, as was
-+
+    already the case with the legacy API. Avoids problems when calling underlying
-+
+    Firebird API in multiple threads.
-+
-+
+. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility
-+
+    reasons.
-+
-+
+. IDBInformation.DecodeVersionString now supported isc_info_firebird_version.
-+
-+
+. TSQLXMLReader: handle 'blob' as a reserved word
-+
-+
+. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString).
-+
-+
-+
+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
-+
-+
+. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
-+
+   used to get an IBError Message instead of isc_interprete.
-+
-+
+. Internal tidyup. Native code now used for decoding integers and the events
-+
+    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
-+
+    isc_event_block and isc_event_counts.
-+
-+
+. New IAttachment function
-+
+     function GetAttachmentID: integer;
-+
-+
+. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
-+
+    subclasses to enable UDR support.
-+
-+
+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.
