48	>
49	>	1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
50	>
51	>	2. Remove constraint in IAttachment.HasScollableCursors that returned false when
52	>	using remote protocol. Scrollable cursors with remote database expected to
53	>	be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
54	>	a not supported error.
55	>
56	>	3. IStatement: new function;
57	>	TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
58	>	TStatementFlags = set of TStatementFlag;
59	>	function GetFlags: TStatementFlags;
60	>
61	>	4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
62	>	compatibility.
63	>	In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
64	>	type changes from ExecProcedure to Select. So that ExecuteQuery can continue
65	>	to be used with Update...Retruning statements that return a singleton row,
66	>	instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
67	>	it will open the cursor and return the first row only.
68	>
69	>	5. ITransaction: new functions:
70	>	function GetIsReadOnly: boolean;
71	>	function GetTransactionID: integer;
72	>	function GetTrInformation(Requests: array of byte): ITrInformation; overload;
73	>	function GetTrInformation(Request: byte): ITrInformation; overload;
74	>
75	>	The latter two return the Transaction Information block. The first two extract
76	>	information the Transaction Information block
77	>
78	>	6. New function TSQLTokeniser.ReadCharacters
79	>	Used internally.
80	>
81	>	7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
82	>	parameter placeholders instead of named parameters.
83	>
84	>	8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
85	>	transaction handle is now ignored if Rollback/Commit is called with Force=true
86	>
87	>	FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
88	>
89	>	1. TFBClientAPI.GetProcAddr. Add check for nil reference.
90	>
91	>	2. IStatement: new methods:
92	>	procedure SetStaleReferenceChecks(Enable:boolean); {default true}
93	>	function GetStaleReferenceChecks: boolean;
94	>
95	>	In previous versions, stale reference checks were always enabled. This allows the
96	>	user to disable them on a per statement basis. Note this can risk out-of-date
97	>	statement BLR. See User Guide.
98	>
99	>	3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
100	>	stored procedure and hence avoids replacing named parameters within a containing
101	>	BEGIN..END block.
102	>
103	>	4. ISQLParam: using a string value to set an integer field with a scale factor of
104	>	zero is now treated as a special case to avoid the risk of floating point
105	>	rounding errors affecting pure integers.
106	>
107	>	5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
108	>
109	>	6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
110	>	SQL Parameter metadata (methods moved from ISQLParam).
111	>
112	>	7. ISQLParam: new method
113	>	function getColMetadata: IParamMetaData;
114	>	This instance of IParamMetaData returns the original column metadata which is unmutable.
115	>	Note: ISQLParam metadata can change after a parameter value has been set e.g when
116	>	setting a VARCHAR column to an integer value.
117	>
118	>	8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
119	>	procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
120	>	also IAttachment:
121	>	function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
122	>	function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
123	>	function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
124	>	aSQLDialect: integer; GenerateParamNames: boolean=false;
125	>	CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
126	>	function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
127	>	GenerateParamNames: boolean=false;
128	>	CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
129	>
130	>	9. Support for scrollable cursors added. New/updated methods:
131	>	IAttachment:
132	>	function HasScollableCursors: boolean;
133	>	function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
134	>	Scrollable: boolean=false): IResultSet; overload;
135	>	function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
136	>	function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
137	>	params: array of const): IResultSet; overload;
138	>	function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
139	>	params: array of const): IResultSet; overload;
140	>	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
141	>	params: array of const): IResultSet; overload;
142	>	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
143	>	Scrollable: boolean=false): IResultSet; overload;
144	>	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
145	>	function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
146	>	params: array of const): IResultSet; overload;
147	>	function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
148	>	function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
149	>	params: array of const): IResultSet; overload;
150	>	IStatement:
151	>	function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
152	>	IResultSet:
153	>	function FetchPrior: boolean; {fetch previous record}
154	>	function FetchFirst:boolean; {fetch first record}
155	>	function FetchLast: boolean; {fetch last record}
156	>	function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
157	>	function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
158	>	function IsBof: boolean;
159	>
160	>	10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
161	>
162	>	11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
163	>	may be noticeable when a line separator occurs inside quoted text. The quoted text
164	>	output by the tokeniser will now use the platform specific lineEnding regardless
165	>	of whether the input uses the CRLF or LF as a line separator.
166	>
167	>	12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
168	>
169	>
170	>	FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
171	>
172	>	1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
173	>
174	>	2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
175	>	will now be encoded inline (i.e. as part of the parameter buffer) if they are
176	>	shorter than a pre-set limit. Longer values continue to be saved as blobs as a
177	>	separate server interaction. This is intended as a performance optimisation.
178	>
179	>	The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
180	>	IAttachment interface functions:
181	>
182	>	function GetInlineBlobLimit: integer;
183	>	procedure SetInlineBlobLimit(limit: integer);
184	>
185	>	3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
186	>	user as the functionality is embedded in the implementation of the IStatement
187	>	interface. Three new functions are defined:
188	>
189	>	procedure AddToBatch;
190	>	function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
191	>	procedure CancelBatch;
192	>	function GetBatchCompletion: IBatchCompletion;
193	>	function GetBatchRowLimit: integer;
194	>	procedure SetBatchRowLimit(aLimit: integer);
195	>
196	>	Also
197	>
198	>	function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
199	>	function HasBatchMode: boolean;         {true if and only if IBatch Supported}
200	>
201	>	For more information see the User Guide.
202	>
203	>	4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
204	>	provided with the EIBInterBaseError now include all three parts.
205	>
206	>	5. Firebird.pas and include files updated to Firebird 4.0.0
207	>
208	>	6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
209	>	Returns SQL Statement type as a text string;
210	>
211	>	7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
212	>	an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
213	>

215
216		1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
217		typo in FB30Statement.pas that caused an unknown parameter error.
