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 Note this can risk out-of-date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 >
214 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
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.
218 >
219 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
220 >
221 > 1. Imported (Firebird) constants updated for Firebird 4.
222 >
223 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
224 >
225 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
226 >
227 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
228 >
229 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
230 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
231 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
232 >   type safe access to the Firebird IMaster interface and avoids the need to turn
233 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
234 >
235 > 6. New IFirebirdAPI Calls:
236 >    function HasLocalTZDB: boolean;
237 >    function HasTimeZoneSupport: boolean;
238 >    function HasExtendedTZSupport: boolean;
239 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
240 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
241 >
242 > 7. New IAttachment Calls:
243 >    function HasDecFloatSupport: boolean;
244 >    function GetTimeZoneServices: ITimeZoneServices;
245 >    function HasTimeZoneSupport: boolean;
246 >
247 > 8. New Interface ITimeZoneServices.
248 >
249 > 9. New ISQLData API Calls:
250 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
251 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

253 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
254 >    function GetAsUTCDateTime: TDateTime;
255 >    function GetAsBCD: tBCD;

270 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
271 >    procedure SetAsBcd(aValue: tBCD);
272 >
273 > 11. New IArray API Calls
274 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
275 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

294 >      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
295 >    This is used to add a parameter block item by the string equivalent of its

305 >
306 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
307 >   with a Firebrid 3 client library.
308 >
309 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
310 >    If a client library path is not explicitly provided and the FIREBIRD environment
311 >    variable is set then the directory given by this variable and any 'lib' subdirectory
312 >    are searched for the Firebird client library. Only if none is found, is the default

314 >
315 > 3.  IUtil.FormatStatus now used to format error messages when using new API
316 >
317 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
318 >
319 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
320 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
321 >    that the byte length corresponds to the number of characters specified for the column.
