11     statement BLR. See User Guide.

13 + 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
14 +   stored procedure and hence avoids replacing named parameters within a containing
15 +   BEGIN..END block.
16 +
17 + 4. ISQLParam: using a string value to set an integer field with a scale factor of
18 +   zero is now treated as a special case to avoid the risk of floating point
19 +   rounding errors affecting pure integers.
20 +
21 + 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
22 +
23 + 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
24 +   SQL Parameter metadata (methods moved from ISQLParam).
25 +
26 + 7. ISQLParam: new method
27 +     function getColMetadata: IParamMetaData;
28 +   This instance of IParamMetaData returns the original column metadata which is unmutable.
29 +   Note: ISQLParam metadata can change after a parameter value has been set e.g when
30 +   setting a VARCHAR column to an integer value.
31 +
32 + 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
33 +    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
34 +   also IAttachment:
35 +    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
36 +    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
37 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
38 +                       aSQLDialect: integer; GenerateParamNames: boolean=false;
39 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
40 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
41 +                       GenerateParamNames: boolean=false;
42 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
43 +
44 + 9. Support for scrollable cursors added. New/updated methods:
45 +   IAttachment:
46 +    function HasScollableCursors: boolean;
47 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
48 +                             Scrollable: boolean=false): IResultSet; overload;
49 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
50 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
51 +                             params: array of const): IResultSet; overload;
52 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
53 +                             params: array of const): IResultSet; overload;
54 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
55 +                             params: array of const): IResultSet; overload;
56 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
57 +                             Scrollable: boolean=false): IResultSet; overload;
58 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
59 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
60 +                             params: array of const): IResultSet; overload;
61 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
62 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
63 +                             params: array of const): IResultSet; overload;
64 +   IStatement:
65 +     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
66 +   IResultSet:
67 +    function FetchPrior: boolean; {fetch previous record}
68 +    function FetchFirst:boolean; {fetch first record}
69 +    function FetchLast: boolean; {fetch last record}
70 +    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
71 +    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
72 +    function IsBof: boolean;
73 +
