1 + FBINTF Change Log  version          (1.3-2 Build 12878) Sat, 23 Oct 2021 13:23:39 +0100
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 Note this can risk out-of-date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 +
