1 FBINTF Change Log version (1.4-1 Build 14019) Sat, 05 Aug 2023 13:21:51 +0100
2
3 1. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error
4 checks for range checking.
5
6 FBINTF Change Log version (1.4-0 Build 14011) Sat, 05 Aug 2023 11:09:09 +0100
7
8 1. Support package fbudr added for support of User Defined Routines (UDRs), and package
9 fbudrtestbed for client side debugging of UDR libraries.
10
11 2. Package layout changed with introduction of udr support. IB*.pas files moved from
12 root directory to "client". IBHeader moved to "Client".
13
14 3. Delphi packages: all packages now compile .dcp and .bpi files to either
15 fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing
16 fbintf.dcp and fbintf.bpi files from other locations.
17
18 4. Client side journaling support added. Interface changes
19 IAttachment
20 function JournalingActive: boolean;
21 function GetJournalOptions: TJournalOptions;
22 function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
23 function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
24 function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
25 procedure StopJournaling(RetainJournal: boolean);
26
27 5. Transactions may now be given a local transaction name:
28 IFirebirdAPI
29 function StartTransaction(Attachments: array of IAttachment;
30 TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
31 TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
32 aName: AnsiString=''): ITransaction; overload;
33 function StartTransaction(Attachments: array of IAttachment;
34 TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
35 TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
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;
45 DefaultCompletion: TTransactionCompletion=taCommit;
46 aName: AnsiString=''): ITransaction; overload;
47
48 ITransaction
49 function GetTransactionName: AnsiString;
50 procedure SetTransactionName(aValue: AnsiString);
51
52 6. Additional Transaction information
53 ITPB.function AsText: AnsiString; {Returns TPB as a text string}
54
55 ITransaction
56 function GetDefaultCompletion: TTransactionCompletion;
57 function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
58
59 7. New IAttachment helper functions
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;
348 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
349 function GetAsUTCDateTime: TDateTime;
350 function GetAsBCD: tBCD;
351 function GetStatement: IStatement;
352 function GetTransaction: ITransaction;
353 procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
354 procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
355 procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); 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;
363 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
364 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
365 function GetAsUTCDateTime(index: array of integer): TDateTime;
366 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
367 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
368 procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); 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
380 13. IDPB, ITPB and ISPB: new interface method
381 function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
382 This is used to add a parameter block item by the string equivalent of its
383 symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
384
385 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
386 function getParamTypeName: AnsiString;
387
388 15. fb_shutdown now called before unloading Firebird library. This can avoid a
389 SIGEVENT error when a programme using the embeded server is unloaded.
390
391 FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
392
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;
415 function GetClientMinor: integer;
416
417 7. IColumnMetaData and IArrayMetaData: new method
418 function GetCharSetWidth: integer;
419
420 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
421
422 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
423 case sensitive
424
425 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
426
427 3. New API Calls:
428 IColumnMetaData.GetStatement
429 IColumnMetaData.GetTransaction
430 ISQLData.GetStrDataLength
431 IResults.GetStatement
432 IAttachment.OpenBlob (using Blob metadata)
433 IAttachment.OpenArray (using array metadata)
434
435 4. FBMessages: removal of unused messages
436
437 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
438
439 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
440
441 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
442
443 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
444 where the second character of the parameter name is a numeric.
445
446 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
447 This returns the isc_version connection information as one or more lines.
448 This is the same information as returned by isql with the -z option.
449
450 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
451 is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
452 compiler option then the Firebird 3 API is no longer compiled in.
453
454 4. IColumnMetaData: new method.
455
456 TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
457 dfDateTime, {SQL DATETIME}
458 dfTime);
459
460 function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
461
462 This returns the max. number of characters returned by the "AsString" method
463 when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
464
465 5. Additional argument for IAttachment.PrepareWithNamedParameters -
466 CaseSensitiveParams: boolean = false
467
468 If this argument is set to true then SQL parameter names are assumed to be case
469 sensitive and must be referenced (using ISQLParams.ByName) using the case
470 sensitive name.
471
472 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
473 is of type VarChar or Char to set the parameter to a numeric value (e.g. using
474 .AsCurrency) and then subsequently to update the value to a non-numeric string
475 using .AsString.

479 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
480
481 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
482
483 2. Restrict IsMultiThread check to Unix only for compatibility with
484 https://bugs.freepascal.org/view.php?id=30535
485
486 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
487 named parameters and is intended to avoid problems with (e.g.) Execute Block
488 and processing internal parameters as statement parameters.
489
490 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
491 or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
492
493 5. New function added to IB.pas
494
495 function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
496
497 This allows a Firebird Library to be loaded from an explicit path. use the
498 IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
499 the library. It is possible to load Firebird libraries from different locations
500 simultaneously, each with a distinct IFirebirdAPI.
501
502 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
503
504 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
505 program compiled with -CR command line switch.
506
507 2. IServiceManager additions (informational):
508 function getProtocol: TProtocol;
509 function getPortNo: AnsiString;
510
511 3. IServiceManager improved error handling. Interfaces changed:
512 function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
513 function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
514 function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
515
516 4. IAttachment addition (informational)
517 function GetSecurityDatabase: AnsiString;
518
519 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
520 thus now returns accumulated stats for a select statement from opening a cursor
521 up to the last fetch.
522
523 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
524 the problem.
525
526 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
527 replaces deprecated "comp" type.
528
529 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
530
531 11. URL Connection Strings: inet4 and inet6 now recognised.
532
533 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
534
535 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
536
537
538 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
539
540 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
541
542 2. IAttachment: add two new methods
543 function HasDefaultCharSet: boolean;
544 function GetDefaultCharSetID: integer;
545
546 These return, respectively, true if a connection default character set was
547 specified and the character set id of the connection default character set.
548 The DefaultCharSetID is cached when the connection is opened and hence does not
549 require a database lookup.
550
551 3. Avoid exception when a text blob is a stored procedure parameter.
552
553 4. Update test suite to include a test for a stored proc returning a text blob.
554
555 5. IAttachment: add
556 function GetRemoteProtocol: AnsiString;
557 function GetODSMajorVersion: integer;
558 function GetODSMinorVersion: integer;
559 function GetAuthenticationMethod: AnsiString;
560
561 These results are cached when the connection is opened and hence do not
562 require a database lookup.
563
564 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
565 connect string used to create/connect to the database.
566
567 7. IAttachment: Create Database using SQL statement. The username and password
568 are now extracted and used to populate a DPB made available via IAttachment.getDPB.
569 It is now possible to use IAttachment disconnect/connect to reconnect to
570 a database for which the initial connection was established by a create
571 database sql statement. Available in FPC only.
572
573 8. Update Test 1 to test 5, 6 and 7 above.
574
575 9. IBUtils code tidy up.
576
577 10. Parameter Block interfaces "find" method. As documented, this should have
578 returned a nil interface when the item could not be found. Instead, an empty
579 interface item was returned. "Find" now works as documented and will return
580 a nil interface if the item cannot be found.
581
582 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
583
584 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
585 requests with additional parameters. This is to enable support for fb_info_page_contents
586 (return of page contents). Response to fb_info_page_contents returned as
587 a string with code page CP_NONE.
588
589 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
590 test suite updated.
591
592 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
593 a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
594
595 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
596 An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
597 default connection port to be specified.
598
599 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
600
601 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
602 Scale is no longer ignored.
603
604 2. Fix issues with setting SQL Param values using SetAsString with Date values
605 not in locale format but which are recognised by Firebird. Date values that
606 cannot be converted to a string using Pascal library are now passed through
607 to Firebird as Text Strings.
608
609 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
610 UTF8 and not UNICODE_FSS.
611
612 4. Charset ID problem. When using Firebird 3, with no default database character set
613 and a column has a non-default collation specified, an incorrect character set
614 id was being reported that could result in a 'division by zero' error when
615 used by IBX. This has now been fixed.
616
617 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
618 CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
619 the character sets supported can be updated on a per database basis. That is
620 it is possible to add a (Firebird) user defined character set to a database.
621
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.
653
654
655 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
656
657 1. Change syntax to Mode Delphi
658
659 2. Change all uses of string type to explicit AnsiString in order to ensure
660 compatibility between Delphi and FPC.
661
662 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
663 defined for each interface.
664
665 4. Generics syntax variations for Delphi added
666
667 5. PChar replaced with PByte expect where an actual string is being referenced,
668 where PAnsiChar is used instead.
669
670 6. Review of type definitions in IBExternals to ensure Delphi compatibility
671
672 7. Testsuite updated for Delphi
673
674 FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
675
676 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
677 large blobs and the FB3 API.
678
679 2. Update Event Handling algorithm to avoid looping due to recreation of the
680 event block.
681
682 3. Avoid invalid XSQLDA error when the only parameter is updated to null
683
684 4. Array Handling: fix problem with text arrays with character set none. When the
685 DB connection has a default character set (e.g. UTF8), an error is raised by
686 Firebird if the space allocated is not enough to allow for transliteration, even
687 though it is not required for character set none.
688
689 5. IBUtils: List of reserved words brought up-to-date
690
691 6. Add ISQL style performance statistics collection to IStatement
692
693 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
694 CREATE DATABASE statement.
695
696 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
697 an array dimension is not mistaken for a named parameter prefix.
698
699 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
700 when Character set is octets. Avoids loss of non printable characters at start of string.
701
702 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
703 statistics for the last action. Requires use of procedure IStatement.EnableStatistics
704 to enable stats gathering.
705
706 11. API Version information added as constants to IB.pas
707
708 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
709
710 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
711
