2 >
3 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
4 >
5 > 2. IStatement: new methods:
6 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
7 >    function GetStaleReferenceChecks: boolean;
8 >
9 >   In previous versions, stale reference checks were always enabled. This allows the
10 >   user to disable them on a per statement basis. Note this can risk out-of-date
11 >   statement BLR. See User Guide.
12 >
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 >
74 > 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
75 >
76 > 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
77 >    may be noticeable when a line separator occurs inside quoted text. The quoted text
78 >    output by the tokeniser will now use the platform specific lineEnding regardless
79 >    of whether the input uses the CRLF or LF as a line separator.
80 >
81 > 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
82 >
83 >
84 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
85 >
86 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
87 >
88 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
89 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
90 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
91 >   separate server interaction. This is intended as a performance optimisation.
92 >
93 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
94 >   IAttachment interface functions:
95 >
96 >    function GetInlineBlobLimit: integer;
97 >    procedure SetInlineBlobLimit(limit: integer);
98 >
99 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
100 >   user as the functionality is embedded in the implementation of the IStatement
101 >   interface. Three new functions are defined:
102 >
103 >    procedure AddToBatch;
104 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
105 >    procedure CancelBatch;
106 >    function GetBatchCompletion: IBatchCompletion;
107 >    function GetBatchRowLimit: integer;
108 >    procedure SetBatchRowLimit(aLimit: integer);
109 >
110 >   Also
111 >
112 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
113 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
114 >
115 >   For more information see the User Guide.
116 >
117 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
118 >   provided with the EIBInterBaseError now include all three parts.
119 >
120 > 5. Firebird.pas and include files updated to Firebird 4.0.0
121 >
122 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
123 >   Returns SQL Statement type as a text string;
124 >
125 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
126 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
127 >
128 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
129 >
130 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
131 >   typo in FB30Statement.pas that caused an unknown parameter error.
132 >
