54 > 6. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
55 >    function GetStatement: IStatement;
56 >    function GetTransaction: ITransaction;
57 >    function GetAttachment: IAttachment;
58 >
59 > 7. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
60 >   interfaces.
61 >
62 > 8. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
63 >   and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
64 >   functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
65 >   of numerics without loss of precision.
66 >
67 > 9. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
68 >
69 > 10. ISQLParams new method "Clear"
70 >
71 > 11. Support package fbudr added for support of User Defined Routines (UDRs).
72 >
73 > 12. Package layout changed with introduction of udr support. IB*.pas files moved from
74 >    root directory to "client".

76 >
77 > FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
78 >
79 > 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
80 >
81 > 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
82 >   using remote protocol. Scrollable cursors with remote database expected to
83 >   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
84 >   a not supported error.
85 >
86 > 3. IStatement: new function;
87 >    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
88 >    TStatementFlags = set of TStatementFlag;
89 >    function GetFlags: TStatementFlags;
90 >
91 > 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
92 >   compatibility.
93 >   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
94 >   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
95 >   to be used with Update...Retruning statements that return a singleton row,
96 >   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
97 >   it will open the cursor and return the first row only.
98 >
99 > 5. ITransaction: new functions:
100 >    function GetIsReadOnly: boolean;
101 >    function GetTransactionID: integer;
102 >    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
103 >    function GetTrInformation(Request: byte): ITrInformation; overload;
104 >
105 >   The latter two return the Transaction Information block. The first two extract
106 >   information the Transaction Information block
107 >
108 > 6. New function TSQLTokeniser.ReadCharacters
109 >   Used internally.
110 >
111 > 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
112 >   parameter placeholders instead of named parameters.
113 >
114 > 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
115 >   transaction handle is now ignored if Rollback/Commit is called with Force=true
116 >
117 > 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
118 >   used to get an IBError Message instead of isc_interprete.
119 >
120 > 10. Internal tidyup. Native code now used for decoding integers and the events
121 >    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
122 >    isc_event_block and isc_event_counts.
123 >
124 > 11. New IAttachment function
125 >     function GetAttachmentID: integer;
126 >
127 > 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
128 >    subclasses to enable UDR support.
129 >
130 > FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
131 >
132 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
133 >
134 > 2. IStatement: new methods:
135 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
136 >    function GetStaleReferenceChecks: boolean;
137 >
138 >   In previous versions, stale reference checks were always enabled. This allows the
139 >   user to disable them on a per statement basis. Note this can risk out-of-date
140 >   statement BLR. See User Guide.
141 >
142 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
143 >   stored procedure and hence avoids replacing named parameters within a containing
144 >   BEGIN..END block.
145 >
146 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
147 >   zero is now treated as a special case to avoid the risk of floating point
148 >   rounding errors affecting pure integers.
149 >
150 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
151 >
152 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
153 >   SQL Parameter metadata (methods moved from ISQLParam).
154 >
155 > 7. ISQLParam: new method
156 >     function getColMetadata: IParamMetaData;
157 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
158 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
159 >   setting a VARCHAR column to an integer value.
160 >
161 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
162 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
163 >   also IAttachment:
164 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
165 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
166 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
167 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
168 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
169 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
170 >                       GenerateParamNames: boolean=false;
171 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
172 >
173 > 9. Support for scrollable cursors added. New/updated methods:
174 >   IAttachment:
175 >    function HasScollableCursors: boolean;
176 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
177 >                             Scrollable: boolean=false): IResultSet; overload;
178 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
179 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
180 >                             params: array of const): IResultSet; overload;
181 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
182 >                             params: array of const): IResultSet; overload;
183 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
184 >                             params: array of const): IResultSet; overload;
185 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
186 >                             Scrollable: boolean=false): IResultSet; overload;
187 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
188 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
189 >                             params: array of const): IResultSet; overload;
190 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
191 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
192 >                             params: array of const): IResultSet; overload;
193 >   IStatement:
194 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
195 >   IResultSet:
196 >    function FetchPrior: boolean; {fetch previous record}
197 >    function FetchFirst:boolean; {fetch first record}
198 >    function FetchLast: boolean; {fetch last record}
199 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
200 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
201 >    function IsBof: boolean;
202 >
203 > 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
204 >
205 > 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
206 >    may be noticeable when a line separator occurs inside quoted text. The quoted text
207 >    output by the tokeniser will now use the platform specific lineEnding regardless
208 >    of whether the input uses the CRLF or LF as a line separator.
209 >
210 > 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
211 >
212 >
213 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
214 >
215 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
216 >
217 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
218 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
219 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
220 >   separate server interaction. This is intended as a performance optimisation.
221 >
222 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
223 >   IAttachment interface functions:
224 >
225 >    function GetInlineBlobLimit: integer;
226 >    procedure SetInlineBlobLimit(limit: integer);
227 >
228 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
229 >   user as the functionality is embedded in the implementation of the IStatement
230 >   interface. Three new functions are defined:
231 >
232 >    procedure AddToBatch;
233 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
234 >    procedure CancelBatch;
235 >    function GetBatchCompletion: IBatchCompletion;
236 >    function GetBatchRowLimit: integer;
237 >    procedure SetBatchRowLimit(aLimit: integer);
238 >
239 >   Also
240 >
241 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
242 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
243 >
244 >   For more information see the User Guide.
245 >
246 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
247 >   provided with the EIBInterBaseError now include all three parts.
248 >
249 > 5. Firebird.pas and include files updated to Firebird 4.0.0
250 >
251 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
252 >   Returns SQL Statement type as a text string;
253 >
254 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
255 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
256 >
257 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
258 >
259 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
260 >   typo in FB30Statement.pas that caused an unknown parameter error.
261 >
262 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
