36 >             aName: AnsiString=''): ITransaction; overload;
37 >
38 >   IAttachment
39 >    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
40 >    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
41 >    function StartTransaction(TPB: array of byte;
42 >                              DefaultCompletion: TTransactionCompletion=taCommit;
43 >                              aName: AnsiString=''): ITransaction; overload;
44 >    function StartTransaction(TPB: ITPB;

54 >
55 >   ITransaction
56 >     function GetDefaultCompletion: TTransactionCompletion;
57 >     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}

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

356 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
357 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
358 >    procedure SetAsBcd(aValue: tBCD);
359 >
360 > 11. New IArray API Calls
361 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
362 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

369 >    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
370 >
371 > 12. Utility functions in IBUtils
372 >    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
373 >              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
374 >    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
375 >    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
376 >    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
377 >    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
378 >    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
379 >

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

601   1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
602     Scale is no longer ignored.
# Line 24 | Line 622 | FBINTF Change Log  version             (
622   6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
623     set supported by Firebird with the API.
624  
625 + 7. Add missing isc_info_db_read_only to list of decoded Database Information items
626 +   in FBOutputBlock.pas and update test suite to include this item.
627 +
628 + 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
629 +
630 + 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
631 +   library or finding it by disk location, the PATH environment variable is now also set to
632 +   include the FIREBIRD directory. This is to ensure that the correct dlls in the
633 +   firebird client library dependencies are loaded.
634 +
635 + 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
636 +
637 + 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
638 +
639 + 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
640 +
641 + 13. FB30Statement: A check has been added to ensure that all SQL Parameters
642 +    have been given a value (including NULL). Previously, failing to set the
643 +    value of an SQL Parameter could give rise to unpredictable results or
644 +    an SQLDA error.
645 +
646 + 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
647 +
648 + 15. FBAttachment: Avoid string reference count error when processing an Ansistring
649 +    parameter in an array of const passed to IAttachment.OpenCursor, etc.
650 +
651 + 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
652 +    of const passed to IAttachment.OpenCursor, etc.
