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 >
85 > FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
86 >
87 > 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
88 >
89 > 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
90 >   using remote protocol. Scrollable cursors with remote database expected to
91 >   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
92 >   a not supported error.
93 >
94 > 3. IStatement: new function;
95 >    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
96 >    TStatementFlags = set of TStatementFlag;
97 >    function GetFlags: TStatementFlags;
98 >
99 > 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
100 >   compatibility.
101 >   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
102 >   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
103 >   to be used with Update...Retruning statements that return a singleton row,
104 >   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
105 >   it will open the cursor and return the first row only.
106 >
107 > 5. ITransaction: new functions:
108 >    function GetIsReadOnly: boolean;
109 >    function GetTransactionID: integer;
110 >    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
111 >    function GetTrInformation(Request: byte): ITrInformation; overload;
112 >
113 >   The latter two return the Transaction Information block. The first two extract
114 >   information the Transaction Information block
115 >
116 > 6. New function TSQLTokeniser.ReadCharacters
117 >   Used internally.
118 >
119 > 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
120 >   parameter placeholders instead of named parameters.
121 >
122 > 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
123 >   transaction handle is now ignored if Rollback/Commit is called with Force=true
124 >
125 > 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
126 >   used to get an IBError Message instead of isc_interprete.
127 >
128 > 10. Internal tidyup. Native code now used for decoding integers and the events
129 >    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
130 >    isc_event_block and isc_event_counts.
131 >
132 > 11. New IAttachment function
133 >     function GetAttachmentID: integer;
134 >
135 > 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
136 >    subclasses to enable UDR support.
137 >
138 > FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
139 >
140 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
141 >
142 > 2. IStatement: new methods:
143 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
144 >    function GetStaleReferenceChecks: boolean;
145 >
146 >   In previous versions, stale reference checks were always enabled. This allows the
147 >   user to disable them on a per statement basis. Note this can risk out-of-date
148 >   statement BLR. See User Guide.
149 >
150 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
151 >   stored procedure and hence avoids replacing named parameters within a containing
152 >   BEGIN..END block.
153 >
154 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
155 >   zero is now treated as a special case to avoid the risk of floating point
156 >   rounding errors affecting pure integers.
157 >
158 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
159 >
160 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
161 >   SQL Parameter metadata (methods moved from ISQLParam).
162 >
163 > 7. ISQLParam: new method
164 >     function getColMetadata: IParamMetaData;
165 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
166 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
167 >   setting a VARCHAR column to an integer value.
168 >
169 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
170 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
171 >   also IAttachment:
172 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
173 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
174 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
175 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
176 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
177 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
178 >                       GenerateParamNames: boolean=false;
179 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
180 >
181 > 9. Support for scrollable cursors added. New/updated methods:
182 >   IAttachment:
183 >    function HasScollableCursors: boolean;
184 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
185 >                             Scrollable: boolean=false): IResultSet; overload;
186 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
187 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
188 >                             params: array of const): IResultSet; overload;
189 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
190 >                             params: array of const): IResultSet; overload;
191 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
192 >                             params: array of const): IResultSet; overload;
193 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
194 >                             Scrollable: boolean=false): IResultSet; overload;
195 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
196 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
197 >                             params: array of const): IResultSet; overload;
198 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
199 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
200 >                             params: array of const): IResultSet; overload;
201 >   IStatement:
202 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
203 >   IResultSet:
204 >    function FetchPrior: boolean; {fetch previous record}
205 >    function FetchFirst:boolean; {fetch first record}
206 >    function FetchLast: boolean; {fetch last record}
207 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
208 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
209 >    function IsBof: boolean;
210 >
211 > 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
212 >
213 > 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
214 >    may be noticeable when a line separator occurs inside quoted text. The quoted text
215 >    output by the tokeniser will now use the platform specific lineEnding regardless
216 >    of whether the input uses the CRLF or LF as a line separator.
217 >
218 > 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
219 >
220 >
221 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
222 >
223 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
224 >
225 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
226 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
227 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
228 >   separate server interaction. This is intended as a performance optimisation.
229 >
230 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
231 >   IAttachment interface functions:
232 >
233 >    function GetInlineBlobLimit: integer;
234 >    procedure SetInlineBlobLimit(limit: integer);
235 >
236 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
237 >   user as the functionality is embedded in the implementation of the IStatement
238 >   interface. Three new functions are defined:
239 >
240 >    procedure AddToBatch;
241 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
242 >    procedure CancelBatch;
243 >    function GetBatchCompletion: IBatchCompletion;
244 >    function GetBatchRowLimit: integer;
245 >    procedure SetBatchRowLimit(aLimit: integer);
246 >
247 >   Also
248 >
249 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
250 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
251 >
252 >   For more information see the User Guide.
253 >
254 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
255 >   provided with the EIBInterBaseError now include all three parts.
256 >
257 > 5. Firebird.pas and include files updated to Firebird 4.0.0
258 >
259 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
260 >   Returns SQL Statement type as a text string;
261 >
262 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
263 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
264 >
265 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
266 >
267 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
268 >   typo in FB30Statement.pas that caused an unknown parameter error.
269 >
270 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
271 >
272 > 1. Imported (Firebird) constants updated for Firebird 4.
273 >
274 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
275 >
276 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
277 >
278 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
279 >
280 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
281 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
282 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
283 >   type safe access to the Firebird IMaster interface and avoids the need to turn
284 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
285 >
286 > 6. New IFirebirdAPI Calls:
287 >    function HasLocalTZDB: boolean;
288 >    function HasTimeZoneSupport: boolean;
289 >    function HasExtendedTZSupport: boolean;
290 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
291 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
292 >
293 > 7. New IAttachment Calls:
294 >    function HasDecFloatSupport: boolean;
295 >    function GetTimeZoneServices: ITimeZoneServices;
296 >    function HasTimeZoneSupport: boolean;
297 >
298 > 8. New Interface ITimeZoneServices.
299 >
300 > 9. New ISQLData API Calls:
301 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
302 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
303 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
304 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
305 >    function GetAsUTCDateTime: TDateTime;
306 >    function GetAsBCD: tBCD;
307 >
308 > 10. New ISQLParam API Calls
309 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
310 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

320 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
321 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
322 >    procedure SetAsBcd(aValue: tBCD);
323 >
324 > 11. New IArray API Calls
325 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
326 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
327 >    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

329 >    function GetAsUTCDateTime(index: array of integer): TDateTime;
330 >    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
331 >    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
332 >    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
333 >    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
334 >
335 > 12. Utility functions in IBUtils
336 >    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
337 >              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
338 >    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
339 >    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
340 >    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
341 >    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
342 >    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
343 >
344 > 13. IDPB, ITPB and ISPB: new interface method
345 >      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
346 >    This is used to add a parameter block item by the string equivalent of its
347 >    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
348 >
349 > 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
350 >      function getParamTypeName: AnsiString;
351 >
352 > 15. fb_shutdown now called before unloading Firebird library. This can avoid a
353 >     SIGEVENT error when a programme using the embeded server is unloaded.
354 >
355 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
356 >
357 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
358 >   with a Firebrid 3 client library.
359 >
360 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
361 >    If a client library path is not explicitly provided and the FIREBIRD environment
362 >    variable is set then the directory given by this variable and any 'lib' subdirectory
363 >    are searched for the Firebird client library. Only if none is found, is the default
364 >    client library used.
365 >
366 > 3.  IUtil.FormatStatus now used to format error messages when using new API
367 >
368 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
369 >
370 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
371 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
372 >    that the byte length corresponds to the number of characters specified for the column.
373 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
374 >    correct behaviour but may affect some implementations that relied upon automatic
375 >    trimming of trailing white space.
376 >

407 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
408 >   where the second character of the parameter name is a numeric.
409 >
410 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
411 >   This returns the isc_version connection information as one or more lines.
412 >   This is the same information as returned by isql with the -z option.

436 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
437 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
438 >   .AsCurrency) and then subsequently to update the value to a non-numeric string

452 >   and processing internal parameters as statement parameters.
453 >
454 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
455 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
456 >
457 > 5. New function added to IB.pas
458 >
459 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary

461 >   This allows a Firebird Library to be loaded from an explicit path. use the
462 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
463 >   the library. It is possible to load Firebird libraries from different locations
464 >   simultaneously, each with a distinct IFirebirdAPI.

480 > 4. IAttachment addition (informational)
481 >    function GetSecurityDatabase: AnsiString;
482 >
483 > 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
484 >   thus now returns accumulated stats for a select statement from opening a cursor
485 >   up to the last fetch.
486 >
487 > 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting

506 > 2. IAttachment: add two new methods
507 >     function HasDefaultCharSet: boolean;
508 >     function GetDefaultCharSetID: integer;
509 >
510 >   These return, respectively, true if a connection default character set was

513 >   require a database lookup.
514 >
515 > 3. Avoid exception when a text blob is a stored procedure parameter.
516 >
517 > 4. Update test suite to include a test for a stored proc returning a text blob.
518 >
519 > 5. IAttachment: add
520 >      function GetRemoteProtocol: AnsiString;
521 >      function GetODSMajorVersion: integer;
522 >      function GetODSMinorVersion: integer;
523 >      function GetAuthenticationMethod: AnsiString;
524 >
525 >   These results are cached when the connection is opened and hence do not
526 >   require a database lookup.
527 >
528 > 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
529 >   connect string used to create/connect to the database.
530 >
531 > 7. IAttachment: Create Database using SQL statement. The username and password
532 >   are now extracted and used to populate a DPB made available via IAttachment.getDPB.
533 >   It is now possible to use IAttachment disconnect/connect to reconnect to
534 >   a database for which the initial connection was established by a create
535 >   database sql statement. Available in FPC only.
536 >
537 > 8. Update Test 1 to test 5, 6 and 7 above.
538 >
539 > 9. IBUtils code tidy up.
540 >
541 > 10. Parameter Block interfaces "find" method. As documented, this should have
542 >   returned a nil interface when the item could not be found. Instead, an empty
543 >   interface item was returned. "Find" now works as documented and will return
544 >   a nil interface if the item cannot be found.
545 >
546 > 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
547 >
548 > 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
549 >    requests with additional parameters. This is to enable support for fb_info_page_contents
550 >    (return of page contents). Response to fb_info_page_contents returned as
551 >    a string with code page CP_NONE.
552 >
553 > 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
554 >    test suite updated.
555 >
556 > 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
557 >    a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
558 >
559 > 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
560 >    An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
561 >    default connection port to be specified.
