1 FBINTF Change Log version (1.4-1 Build 14103) Mon, 27 Nov 2023 14:26:35 +0000
2
3 1. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error
4 checks for range checking.
5
6 2. FB25Client: In GetIBMessage, fb_interpret is now called multiple times such that
7 any additional error information is decoded.
8
9 3. FB25Statement: When changing a param type from Blob sub_type 1 to SQL_TEXT or SQL_VARYING
10 charsetid is now preserved and size is set to default blob size. Now aligns with
11 FB3 and later.
12
13 4. DDL and DML string literals are now explicitly set to the connection character
14 set rather than the default character set provided by the compiler.
15
16 5. General tidy up of transliteration functions, now centralised in IBUtils. FPC testing
17 now makes use of the RTL fpwidestring unit for support of international character
18 sets.
19
20 6. Database exception handling (see section 9.3 in user guide).
21 * For FB3 and later API: Connection Character set now applied to message returned
22 by fb_interpret and message then transliterated if necessary to the system character set.
23 * For Legacy API: The message character set is guessed as UTF8 unless invalid
24 UTF8 characters found when connection character set is assumed. Message then
25 transliterated if necessary to system character set.
26 Note: this difference of behaviour is because legacy API presents exception messages
27 "as is", while FB3 server attempts to transliterate to connection character set.
28
29 FBINTF Change Log version (1.4-0 Build 14011) Sat, 05 Aug 2023 11:09:09 +0100
30
31 1. Support package fbudr added for support of User Defined Routines (UDRs), and package
32 fbudrtestbed for client side debugging of UDR libraries.
33
34 2. Package layout changed with introduction of udr support. IB*.pas files moved from
35 root directory to "client". IBHeader moved to "Client".
36
37 3. Delphi packages: all packages now compile .dcp and .bpi files to either
38 fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing
39 fbintf.dcp and fbintf.bpi files from other locations.
40
41 4. Client side journaling support added. Interface changes
42 IAttachment
43 function JournalingActive: boolean;
44 function GetJournalOptions: TJournalOptions;
45 function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
46 function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
47 function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
48 procedure StopJournaling(RetainJournal: boolean);
49
50 5. Transactions may now be given a local transaction name:
51 IFirebirdAPI
52 function StartTransaction(Attachments: array of IAttachment;
53 TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
54 TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
55 aName: AnsiString=''): ITransaction; overload;
56 function StartTransaction(Attachments: array of IAttachment;
57 TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
58 TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
59 aName: AnsiString=''): ITransaction; overload;
60
61 IAttachment
62 function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
63 function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
64 function StartTransaction(TPB: array of byte;
65 DefaultCompletion: TTransactionCompletion=taCommit;
66 aName: AnsiString=''): ITransaction; overload;
67 function StartTransaction(TPB: ITPB;
68 DefaultCompletion: TTransactionCompletion=taCommit;
69 aName: AnsiString=''): ITransaction; overload;
70
71 ITransaction
72 function GetTransactionName: AnsiString;
73 procedure SetTransactionName(aValue: AnsiString);
74
75 6. Additional Transaction information
76 ITPB.function AsText: AnsiString; {Returns TPB as a text string}
77
78 ITransaction
79 function GetDefaultCompletion: TTransactionCompletion;
80 function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
81
82 7. New IAttachment helper functions
83 function HasTable(aTableName: AnsiString): boolean;
84 function HasFunction(aFunctionName: AnsiString): boolean;
85 function HasProcedure(aProcName: AnsiString): boolean;
86 function GetAttachmentID: integer;
87 function GetCharSetID: integer;
88
89 8. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
90 will be allocated for batch operations.
91
92 9. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
93 function GetStatement: IStatement;
94 function GetTransaction: ITransaction;
95 function GetAttachment: IAttachment;
96
97 10. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
98 interfaces.
99
100 11. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
101 and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
102 functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
103 of numerics without loss of precision.
104
105 12. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
106
107 13. ISQLParams new method "Clear"
108
109 14. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
110 request rather than on attachment connect.
111
112 15. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the
113 fact that SQLCodes are soon to be deprecated. In the future, the other options
114 will be silently ignored if SQLCode support is not present in the Firebird
115 Client library.
116
117 16. ITransaction changes Rollback and Commit from procedures to functions:
118 function Commit(Force: boolean=false): TTrCompletionState;
119 function Rollback(Force: boolean=false): TTrCompletionState;
120
121 Specifically, this is to allow the functions to report back a failed commit or
122 rollback when Force = true. In the case, the transaction handle has been
123 released, while the transaction remains in limbo.
124
125 17. IAttachment ExecImmediate.
126 When the transaction parameters are provided as an array of const and the
127 statement fails, the transaction is rolledback (forced) before the exception
128 is raised.
129
130 18. In Firebird 3 and later API: the status vector is now a thread var, as was
131 already the case with the legacy API. Avoids problems when calling underlying
132 Firebird API in multiple threads.
133
134 19. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility
135 reasons.
136
137 20. IDBInformation.DecodeVersionString now supported isc_info_firebird_version.
138
139 21. TSQLXMLReader: handle 'blob' as a reserved word
140
141 22. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString).
142
143
144 FBINTF Change Log version (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
145
146 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
147
148 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
149 using remote protocol. Scrollable cursors with remote database expected to
150 be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
151 a not supported error.
152
153 3. IStatement: new function;
154 TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
155 TStatementFlags = set of TStatementFlag;
156 function GetFlags: TStatementFlags;
157
158 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
159 compatibility.
160 In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
161 type changes from ExecProcedure to Select. So that ExecuteQuery can continue
162 to be used with Update...Retruning statements that return a singleton row,
163 instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
164 it will open the cursor and return the first row only.
165
166 5. ITransaction: new functions:
167 function GetIsReadOnly: boolean;
168 function GetTransactionID: integer;
169 function GetTrInformation(Requests: array of byte): ITrInformation; overload;
170 function GetTrInformation(Request: byte): ITrInformation; overload;
171
172 The latter two return the Transaction Information block. The first two extract
173 information the Transaction Information block
174
175 6. New function TSQLTokeniser.ReadCharacters
176 Used internally.
177
178 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
179 parameter placeholders instead of named parameters.
180
181 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
182 transaction handle is now ignored if Rollback/Commit is called with Force=true
183
184 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
185 used to get an IBError Message instead of isc_interprete.
186
187 10. Internal tidyup. Native code now used for decoding integers and the events
188 buffer. Avoids dependencies on fbclient functions isc_portable_integer,
189 isc_event_block and isc_event_counts.
190
191 11. New IAttachment function
192 function GetAttachmentID: integer;
193
194 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
195 subclasses to enable UDR support.
196
197 FBINTF Change Log version (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
198
199 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
200
201 2. IStatement: new methods:
202 procedure SetStaleReferenceChecks(Enable:boolean); {default true}
203 function GetStaleReferenceChecks: boolean;
204
205 In previous versions, stale reference checks were always enabled. This allows the
206 user to disable them on a per statement basis. Note this can risk out-of-date
207 statement BLR. See User Guide.
208
209 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
210 stored procedure and hence avoids replacing named parameters within a containing
211 BEGIN..END block.
212
213 4. ISQLParam: using a string value to set an integer field with a scale factor of
214 zero is now treated as a special case to avoid the risk of floating point
215 rounding errors affecting pure integers.
216
217 5. ISQLParam: Review and tidy-up of SetAsString for numeric types.
218
219 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
220 SQL Parameter metadata (methods moved from ISQLParam).
221
222 7. ISQLParam: new method
223 function getColMetadata: IParamMetaData;
224 This instance of IParamMetaData returns the original column metadata which is unmutable.
225 Note: ISQLParam metadata can change after a parameter value has been set e.g when
226 setting a VARCHAR column to an integer value.
227
228 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
229 procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
230 also IAttachment:
231 function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
232 function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
233 function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
234 aSQLDialect: integer; GenerateParamNames: boolean=false;
235 CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
236 function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
237 GenerateParamNames: boolean=false;
238 CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
239
240 9. Support for scrollable cursors added. New/updated methods:
241 IAttachment:
242 function HasScollableCursors: boolean;
243 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
244 Scrollable: boolean=false): IResultSet; overload;
245 function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
246 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
247 params: array of const): IResultSet; overload;
248 function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
249 params: array of const): IResultSet; overload;
250 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
251 params: array of const): IResultSet; overload;
252 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
253 Scrollable: boolean=false): IResultSet; overload;
254 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
255 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
256 params: array of const): IResultSet; overload;
257 function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
258 function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
259 params: array of const): IResultSet; overload;
260 IStatement:
261 function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
262 IResultSet:
263 function FetchPrior: boolean; {fetch previous record}
264 function FetchFirst:boolean; {fetch first record}
265 function FetchLast: boolean; {fetch last record}
266 function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
267 function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
268 function IsBof: boolean;
269
270 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
271
272 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
273 may be noticeable when a line separator occurs inside quoted text. The quoted text
274 output by the tokeniser will now use the platform specific lineEnding regardless
275 of whether the input uses the CRLF or LF as a line separator.
276
277 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
278
279
280 FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
281
282 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
283
284 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
285 will now be encoded inline (i.e. as part of the parameter buffer) if they are
286 shorter than a pre-set limit. Longer values continue to be saved as blobs as a
287 separate server interaction. This is intended as a performance optimisation.
288
289 The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
290 IAttachment interface functions:
291
292 function GetInlineBlobLimit: integer;
293 procedure SetInlineBlobLimit(limit: integer);
294
295 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
296 user as the functionality is embedded in the implementation of the IStatement
297 interface. Three new functions are defined:
298
299 procedure AddToBatch;
300 function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
301 procedure CancelBatch;
302 function GetBatchCompletion: IBatchCompletion;
303 function GetBatchRowLimit: integer;
304 procedure SetBatchRowLimit(aLimit: integer);
305
306 Also
307
308 function IsInBatchMode: boolean; {true after call to execute(eaDefer)}
309 function HasBatchMode: boolean; {true if and only if IBatch Supported}
310
311 For more information see the User Guide.
312
313 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
314 provided with the EIBInterBaseError now include all three parts.
315
316 5. Firebird.pas and include files updated to Firebird 4.0.0
317
318 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
319 Returns SQL Statement type as a text string;
320
321 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
322 an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
323
324 FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
325
326 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
327 typo in FB30Statement.pas that caused an unknown parameter error.
328
329 FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
330
331 1. Imported (Firebird) constants updated for Firebird 4.
332
333 2. Firebird.pas from Firebird 4 integrated into source code tree.
334
335 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
336
337 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
338
339 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
340 QueryInterface may be used to coerce this interface from IFirebirdAPI. The
341 interface provides a single method "function GetIMasterIntf: IMaster". This provides
342 type safe access to the Firebird IMaster interface and avoids the need to turn
343 off object checks when coercing "function GetIMaster: TObject" to IMaster.
344
345 6. New IFirebirdAPI Calls:
346 function HasLocalTZDB: boolean;
347 function HasTimeZoneSupport: boolean;
348 function HasExtendedTZSupport: boolean;
349 procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
350 function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
351
352 7. New IAttachment Calls:
353 function HasDecFloatSupport: boolean;
354 function GetTimeZoneServices: ITimeZoneServices;
355 function HasTimeZoneSupport: boolean;
356
357 8. New Interface ITimeZoneServices.
358
359 9. New ISQLData API Calls:
360 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
361 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
362 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
363 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
364 function GetAsUTCDateTime: TDateTime;
365 function GetAsBCD: tBCD;
366
367 10. New ISQLParam API Calls
368 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
369 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
370 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
371 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
372 function GetAsUTCDateTime: TDateTime;
373 function GetAsBCD: tBCD;
374 function GetStatement: IStatement;
375 function GetTransaction: ITransaction;
376 procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
377 procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
378 procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
379 procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
380 procedure SetAsUTCDateTime(aUTCTime: TDateTime);
381 procedure SetAsBcd(aValue: tBCD);
382
383 11. New IArray API Calls
384 procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
385 procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
386 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
387 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
388 function GetAsUTCDateTime(index: array of integer): TDateTime;
389 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
390 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
391 procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
392 procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
393
394 12. Utility functions in IBUtils
395 function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
396 var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
397 procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
398 function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
399 function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
400 function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
401 function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
402
403 13. IDPB, ITPB and ISPB: new interface method
404 function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
405 This is used to add a parameter block item by the string equivalent of its
406 symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
407
408 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
409 function getParamTypeName: AnsiString;
410
411 15. fb_shutdown now called before unloading Firebird library. This can avoid a
412 SIGEVENT error when a programme using the embeded server is unloaded.
413
414 FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
415
416 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
417 with a Firebrid 3 client library.
418
419 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
420 If a client library path is not explicitly provided and the FIREBIRD environment
421 variable is set then the directory given by this variable and any 'lib' subdirectory
422 are searched for the Firebird client library. Only if none is found, is the default
423 client library used.
424
425 3. IUtil.FormatStatus now used to format error messages when using new API
426
427 4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
428
429 5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
430 returned using GetAsString and the string codepage is UTF8, the string is truncated so
431 that the byte length corresponds to the number of characters specified for the column.
432 SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
433 correct behaviour but may affect some implementations that relied upon automatic
434 trimming of trailing white space.
435
436 6. New IFirebirdAPI Calls:
437 function GetClientMajor: integer;
438 function GetClientMinor: integer;
439
440 7. IColumnMetaData and IArrayMetaData: new method

443 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
444
445 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
446 case sensitive
447
448 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
449
450 3. New API Calls:
451 IColumnMetaData.GetStatement
452 IColumnMetaData.GetTransaction
453 ISQLData.GetStrDataLength
454 IResults.GetStatement
455 IAttachment.OpenBlob (using Blob metadata)
456 IAttachment.OpenArray (using array metadata)
457
458 4. FBMessages: removal of unused messages
459
460 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
461
462 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
463
464 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
465
466 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
467 where the second character of the parameter name is a numeric.
468
469 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
470 This returns the isc_version connection information as one or more lines.
471 This is the same information as returned by isql with the -z option.
472
473 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
474 is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
475 compiler option then the Firebird 3 API is no longer compiled in.
476
477 4. IColumnMetaData: new method.
478
479 TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
480 dfDateTime, {SQL DATETIME}
481 dfTime);
482
483 function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
484
485 This returns the max. number of characters returned by the "AsString" method
486 when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
487
488 5. Additional argument for IAttachment.PrepareWithNamedParameters -
489 CaseSensitiveParams: boolean = false
490
491 If this argument is set to true then SQL parameter names are assumed to be case
492 sensitive and must be referenced (using ISQLParams.ByName) using the case
493 sensitive name.
494
495 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
496 is of type VarChar or Char to set the parameter to a numeric value (e.g. using
497 .AsCurrency) and then subsequently to update the value to a non-numeric string
498 using .AsString.

502 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
503
504 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
505
506 2. Restrict IsMultiThread check to Unix only for compatibility with
507 https://bugs.freepascal.org/view.php?id=30535
508
509 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
510 named parameters and is intended to avoid problems with (e.g.) Execute Block
511 and processing internal parameters as statement parameters.
512
513 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
514 or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
515
516 5. New function added to IB.pas
517
518 function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
519
520 This allows a Firebird Library to be loaded from an explicit path. use the
521 IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
522 the library. It is possible to load Firebird libraries from different locations
523 simultaneously, each with a distinct IFirebirdAPI.
524
525 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
526
527 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
528 program compiled with -CR command line switch.
529
530 2. IServiceManager additions (informational):
531 function getProtocol: TProtocol;
532 function getPortNo: AnsiString;
533
534 3. IServiceManager improved error handling. Interfaces changed:
535 function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
536 function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
537 function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
538
539 4. IAttachment addition (informational)
540 function GetSecurityDatabase: AnsiString;
541
542 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
543 thus now returns accumulated stats for a select statement from opening a cursor
544 up to the last fetch.
545
546 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
547 the problem.
548
549 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
550 replaces deprecated "comp" type.
551
552 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
553
554 11. URL Connection Strings: inet4 and inet6 now recognised.
555
556 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
557
558 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
559
560
561 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
562
563 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
564
565 2. IAttachment: add two new methods
566 function HasDefaultCharSet: boolean;
567 function GetDefaultCharSetID: integer;
568
569 These return, respectively, true if a connection default character set was
570 specified and the character set id of the connection default character set.
571 The DefaultCharSetID is cached when the connection is opened and hence does not
572 require a database lookup.
573
574 3. Avoid exception when a text blob is a stored procedure parameter.
575
576 4. Update test suite to include a test for a stored proc returning a text blob.
577
578 5. IAttachment: add
579 function GetRemoteProtocol: AnsiString;
580 function GetODSMajorVersion: integer;
581 function GetODSMinorVersion: integer;
582 function GetAuthenticationMethod: AnsiString;
583
584 These results are cached when the connection is opened and hence do not
585 require a database lookup.
586
587 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
588 connect string used to create/connect to the database.
589
590 7. IAttachment: Create Database using SQL statement. The username and password
591 are now extracted and used to populate a DPB made available via IAttachment.getDPB.
592 It is now possible to use IAttachment disconnect/connect to reconnect to
593 a database for which the initial connection was established by a create
594 database sql statement. Available in FPC only.
595
596 8. Update Test 1 to test 5, 6 and 7 above.
597
598 9. IBUtils code tidy up.
599
600 10. Parameter Block interfaces "find" method. As documented, this should have
601 returned a nil interface when the item could not be found. Instead, an empty
602 interface item was returned. "Find" now works as documented and will return
603 a nil interface if the item cannot be found.
604
605 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
606
607 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
608 requests with additional parameters. This is to enable support for fb_info_page_contents
609 (return of page contents). Response to fb_info_page_contents returned as
610 a string with code page CP_NONE.
611
612 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
613 test suite updated.
614
615 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
616 a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
617
618 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
619 An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
620 default connection port to be specified.
621
622 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
623
624 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
625 Scale is no longer ignored.
626
627 2. Fix issues with setting SQL Param values using SetAsString with Date values
628 not in locale format but which are recognised by Firebird. Date values that
629 cannot be converted to a string using Pascal library are now passed through
630 to Firebird as Text Strings.
631
632 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
633 UTF8 and not UNICODE_FSS.
634
635 4. Charset ID problem. When using Firebird 3, with no default database character set
636 and a column has a non-default collation specified, an incorrect character set
637 id was being reported that could result in a 'division by zero' error when
638 used by IBX. This has now been fixed.
639
640 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
641 CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
642 the character sets supported can be updated on a per database basis. That is
643 it is possible to add a (Firebird) user defined character set to a database.
644
645 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
646 set supported by Firebird with the API.
647
648 7. Add missing isc_info_db_read_only to list of decoded Database Information items
649 in FBOutputBlock.pas and update test suite to include this item.
650
651 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
652
653 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
654 library or finding it by disk location, the PATH environment variable is now also set to
655 include the FIREBIRD directory. This is to ensure that the correct dlls in the
656 firebird client library dependencies are loaded.
657
658 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
659
660 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
661
662 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
663
664 13. FB30Statement: A check has been added to ensure that all SQL Parameters
665 have been given a value (including NULL). Previously, failing to set the
666 value of an SQL Parameter could give rise to unpredictable results or
667 an SQLDA error.
668
669 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
670
671 15. FBAttachment: Avoid string reference count error when processing an Ansistring
672 parameter in an array of const passed to IAttachment.OpenCursor, etc.
673
674 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
675 of const passed to IAttachment.OpenCursor, etc.
676
677
678 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
679
680 1. Change syntax to Mode Delphi
681
682 2. Change all uses of string type to explicit AnsiString in order to ensure
683 compatibility between Delphi and FPC.
684
685 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
686 defined for each interface.
687
688 4. Generics syntax variations for Delphi added
689
690 5. PChar replaced with PByte expect where an actual string is being referenced,
691 where PAnsiChar is used instead.
692
693 6. Review of type definitions in IBExternals to ensure Delphi compatibility
694
695 7. Testsuite updated for Delphi
696
697 FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
698
699 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
700 large blobs and the FB3 API.
701
702 2. Update Event Handling algorithm to avoid looping due to recreation of the
703 event block.
704
705 3. Avoid invalid XSQLDA error when the only parameter is updated to null
706
707 4. Array Handling: fix problem with text arrays with character set none. When the
708 DB connection has a default character set (e.g. UTF8), an error is raised by
709 Firebird if the space allocated is not enough to allow for transliteration, even
710 though it is not required for character set none.
711
712 5. IBUtils: List of reserved words brought up-to-date
713
714 6. Add ISQL style performance statistics collection to IStatement
715
716 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
717 CREATE DATABASE statement.
718
719 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
720 an array dimension is not mistaken for a named parameter prefix.
721
722 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
723 when Character set is octets. Avoids loss of non printable characters at start of string.
724
725 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
726 statistics for the last action. Requires use of procedure IStatement.EnableStatistics
727 to enable stats gathering.
728
729 11. API Version information added as constants to IB.pas
730
731 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
732
733 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
734
