6 > 2. Package layout changed with introduction of udr support. IB*.pas files moved from
7 >    root directory to "client". IBHeader moved to "Client".
8 >
9 > 3. Delphi packages: all packages now compile .dcp and .bpi files to either
10 >   fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing
11 >   fbintf.dcp and fbintf.bpi files from other locations.
12 >
13 > 4. Client side journaling support added. Interface changes
14 >   IAttachment
15 >    function JournalingActive: boolean;
16 >    function GetJournalOptions: TJournalOptions;
17 >    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
18 >    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
19 >    function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
20 >    procedure StopJournaling(RetainJournal: boolean);
21 >

23 >   IFirebirdAPI
24 >     function StartTransaction(Attachments: array of IAttachment;
25 >             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;

28 >     function StartTransaction(Attachments: array of IAttachment;
29 >             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
30 >             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
31 >             aName: AnsiString=''): ITransaction; overload;
32 >
33 >   IAttachment
34 >    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
35 >    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
36 >    function StartTransaction(TPB: array of byte;
37 >                              DefaultCompletion: TTransactionCompletion=taCommit;
38 >                              aName: AnsiString=''): ITransaction; overload;
39 >    function StartTransaction(TPB: ITPB;
40 >                              DefaultCompletion: TTransactionCompletion=taCommit;
41 >                              aName: AnsiString=''): ITransaction; overload;
42 >
43 >  ITransaction
44 >    function GetTransactionName: AnsiString;
45 >    procedure SetTransactionName(aValue: AnsiString);
46 >
47 > 6. Additional Transaction information
48 >     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
49 >
50 >   ITransaction
51 >     function GetDefaultCompletion: TTransactionCompletion;
52 >     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
53 >
54 > 7. New IAttachment helper functions
55 >     function HasTable(aTableName: AnsiString): boolean;
56 >     function HasFunction(aFunctionName: AnsiString): boolean;
57 >     function HasProcedure(aProcName: AnsiString): boolean;
58 >     function GetAttachmentID: integer;
59 >     function GetCharSetID: integer;
60 >
61 > 8. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
62 >   will be allocated for batch operations.
63 >
64 > 9. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
65 >    function GetStatement: IStatement;
66 >    function GetTransaction: ITransaction;
67 >    function GetAttachment: IAttachment;
68 >
69 > 10. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
70 >    interfaces.
71 >
72 > 11. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
73 >    and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
74 >    functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
75 >    of numerics without loss of precision.
76 >
77 > 12. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
78 >
79 > 13. ISQLParams new method "Clear"
80 >
81 > 14. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
82 >    request rather than on attachment connect.
83 >
84 > 15. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the
85 >    fact that SQLCodes are soon to be deprecated. In the future, the other options
86 >    will be silently ignored if SQLCode support is not present in the Firebird
87 >    Client library.
88 >
89 > 16. ITransaction changes Rollback and Commit from procedures to functions:
90 >      function Commit(Force: boolean=false): TTrCompletionState;
91 >      function Rollback(Force: boolean=false): TTrCompletionState;
92 >
93 >    Specifically, this is to allow the functions to report back a failed commit or
94 >    rollback when Force = true. In the case, the transaction handle has been
95 >    released, while the transaction remains in limbo.
96 >
97 > 17. IAttachment ExecImmediate.
98 >    When the transaction parameters are provided as an array of const and the
99 >    statement fails, the transaction is rolledback (forced) before the exception
100 >    is raised.
101 >
102 > 18. In Firebird 3 and later API: the status vector is now a thread var, as was
103 >    already the case with the legacy API. Avoids problems when calling underlying
104 >    Firebird API in multiple threads.
105 >
106 > 19. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility
107 >    reasons.
108 >
109 > 20. IDBInformation.DecodeVersionString now supported isc_info_firebird_version.
110 >
111 > 21. TSQLXMLReader: handle 'blob' as a reserved word
112 >
113 > 22. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString).
114 >
115 >
116 > FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
117 >
118 > 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
119 >
120 > 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
121 >   using remote protocol. Scrollable cursors with remote database expected to
122 >   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
123 >   a not supported error.
124 >
125 > 3. IStatement: new function;
126 >    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
127 >    TStatementFlags = set of TStatementFlag;
128 >    function GetFlags: TStatementFlags;
129 >
130 > 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
131 >   compatibility.
132 >   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
133 >   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
134 >   to be used with Update...Retruning statements that return a singleton row,
135 >   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
136 >   it will open the cursor and return the first row only.
137 >
138 > 5. ITransaction: new functions:
139 >    function GetIsReadOnly: boolean;
140 >    function GetTransactionID: integer;
141 >    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
142 >    function GetTrInformation(Request: byte): ITrInformation; overload;
143 >
144 >   The latter two return the Transaction Information block. The first two extract
145 >   information the Transaction Information block
146 >
147 > 6. New function TSQLTokeniser.ReadCharacters
148 >   Used internally.
149 >
150 > 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
151 >   parameter placeholders instead of named parameters.
152 >
153 > 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
154 >   transaction handle is now ignored if Rollback/Commit is called with Force=true
155 >
156 > 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
157 >   used to get an IBError Message instead of isc_interprete.
158 >
159 > 10. Internal tidyup. Native code now used for decoding integers and the events
160 >    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
161 >    isc_event_block and isc_event_counts.
162 >
163 > 11. New IAttachment function
164 >     function GetAttachmentID: integer;
165 >
166 > 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
167 >    subclasses to enable UDR support.
168 >
169 > FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
170 >
171 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
172 >
173 > 2. IStatement: new methods:
174 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
175 >    function GetStaleReferenceChecks: boolean;
176 >
177 >   In previous versions, stale reference checks were always enabled. This allows the
178 >   user to disable them on a per statement basis. Note this can risk out-of-date
179 >   statement BLR. See User Guide.
180 >
181 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
182 >   stored procedure and hence avoids replacing named parameters within a containing
183 >   BEGIN..END block.
184 >
185 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
186 >   zero is now treated as a special case to avoid the risk of floating point
187 >   rounding errors affecting pure integers.
188 >
189 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
190 >
191 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
192 >   SQL Parameter metadata (methods moved from ISQLParam).
193 >
194 > 7. ISQLParam: new method
195 >     function getColMetadata: IParamMetaData;
196 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
197 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
198 >   setting a VARCHAR column to an integer value.
199 >
200 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
201 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
202 >   also IAttachment:
203 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
204 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
205 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
206 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
207 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
208 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
209 >                       GenerateParamNames: boolean=false;
210 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
211 >
212 > 9. Support for scrollable cursors added. New/updated methods:
213 >   IAttachment:
214 >    function HasScollableCursors: boolean;
215 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
216 >                             Scrollable: boolean=false): IResultSet; overload;
217 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
218 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
219 >                             params: array of const): IResultSet; overload;
220 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
221 >                             params: array of const): IResultSet; overload;
222 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
223 >                             params: array of const): IResultSet; overload;
224 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
225 >                             Scrollable: boolean=false): IResultSet; overload;
226 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
227 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
228 >                             params: array of const): IResultSet; overload;
229 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
230 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
231 >                             params: array of const): IResultSet; overload;
232 >   IStatement:
233 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
234 >   IResultSet:
235 >    function FetchPrior: boolean; {fetch previous record}
236 >    function FetchFirst:boolean; {fetch first record}
237 >    function FetchLast: boolean; {fetch last record}
238 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
239 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
240 >    function IsBof: boolean;
241 >
242 > 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
243 >
244 > 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
245 >    may be noticeable when a line separator occurs inside quoted text. The quoted text
246 >    output by the tokeniser will now use the platform specific lineEnding regardless
247 >    of whether the input uses the CRLF or LF as a line separator.
248 >
249 > 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
250 >
251 >
252 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
253 >
254 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
255 >
256 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
257 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
258 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
259 >   separate server interaction. This is intended as a performance optimisation.
260 >
261 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
262 >   IAttachment interface functions:
263 >
264 >    function GetInlineBlobLimit: integer;
265 >    procedure SetInlineBlobLimit(limit: integer);
266 >
267 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
268 >   user as the functionality is embedded in the implementation of the IStatement
269 >   interface. Three new functions are defined:
270 >
271 >    procedure AddToBatch;
272 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
273 >    procedure CancelBatch;
274 >    function GetBatchCompletion: IBatchCompletion;
275 >    function GetBatchRowLimit: integer;
276 >    procedure SetBatchRowLimit(aLimit: integer);
277 >
278 >   Also
279 >
280 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
281 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
282 >
283 >   For more information see the User Guide.
284 >
285 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
286 >   provided with the EIBInterBaseError now include all three parts.
287 >
288 > 5. Firebird.pas and include files updated to Firebird 4.0.0
289 >
290 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
291 >   Returns SQL Statement type as a text string;
292 >
293 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
294 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
295 >
296 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
297 >
298 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
299 >   typo in FB30Statement.pas that caused an unknown parameter error.
300 >
301 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
302 >
303 > 1. Imported (Firebird) constants updated for Firebird 4.
304 >
305 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
306 >
307 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
308 >
309 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
310 >
311 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
312 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
313 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
314 >   type safe access to the Firebird IMaster interface and avoids the need to turn
315 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
316 >
317 > 6. New IFirebirdAPI Calls:
318 >    function HasLocalTZDB: boolean;
319 >    function HasTimeZoneSupport: boolean;
320 >    function HasExtendedTZSupport: boolean;
321 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
322 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
323 >
324 > 7. New IAttachment Calls:
325 >    function HasDecFloatSupport: boolean;
326 >    function GetTimeZoneServices: ITimeZoneServices;
327 >    function HasTimeZoneSupport: boolean;
328 >
329 > 8. New Interface ITimeZoneServices.
330 >
331 > 9. New ISQLData API Calls:
332 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
333 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
334 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
335 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
336 >    function GetAsUTCDateTime: TDateTime;
337 >    function GetAsBCD: tBCD;
338 >
339 > 10. New ISQLParam API Calls
340 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
341 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
342 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
343 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
344 >    function GetAsUTCDateTime: TDateTime;
345 >    function GetAsBCD: tBCD;
346 >    function GetStatement: IStatement;
347 >    function GetTransaction: ITransaction;
348 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
349 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
350 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
351 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
352 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
353 >    procedure SetAsBcd(aValue: tBCD);
354 >
355 > 11. New IArray API Calls
356 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
357 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
358 >    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

363 >    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
364 >    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
365 >
366 > 12. Utility functions in IBUtils
367 >    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
368 >              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
369 >    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
370 >    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
371 >    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
372 >    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
373 >    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
374 >
375 > 13. IDPB, ITPB and ISPB: new interface method
376 >      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
377 >    This is used to add a parameter block item by the string equivalent of its
378 >    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
379 >
380 > 14. IDPBItem/ITPBItem/ISPBItem: new interface method:

387 >
388 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
389 >   with a Firebrid 3 client library.
390 >
391 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
392 >    If a client library path is not explicitly provided and the FIREBIRD environment
393 >    variable is set then the directory given by this variable and any 'lib' subdirectory
394 >    are searched for the Firebird client library. Only if none is found, is the default
395 >    client library used.
396 >
397 > 3.  IUtil.FormatStatus now used to format error messages when using new API
398 >
399 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
400 >
401 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
402 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
403 >    that the byte length corresponds to the number of characters specified for the column.
404 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
405 >    correct behaviour but may affect some implementations that relied upon automatic
406 >    trimming of trailing white space.
407 >
408 > 6.  New IFirebirdAPI Calls:
409 >      function GetClientMajor: integer;
410 >      function GetClientMinor: integer;
411 >
412 > 7.  IColumnMetaData and IArrayMetaData: new method

417 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
