1 FBINTF Change Log version (1.4-0 Build 12952) Tue, 07 Dec 2021 11:53:46 +0000
2
3 1. Client side journaling support added. Interface changes
4 IAttachment
5 function JournalingActive: boolean;
6 function GetJournalOptions: TJournalOptions;
7 function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
8 function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
9 function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
10 procedure StopJournaling(RetainJournal: boolean);
11
12 2. Transactions may now be given a local transaction name:
13 IFirebirdAPI
14 function StartTransaction(Attachments: array of IAttachment;
15 TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
16 TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
17 aName: AnsiString=''): ITransaction; overload;
18 function StartTransaction(Attachments: array of IAttachment;
19 TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
20 TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
21 aName: AnsiString=''): ITransaction; overload;
22
23 IAttachment
24 function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
25 function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
26 function StartTransaction(TPB: array of byte;
27 DefaultCompletion: TTransactionCompletion=taCommit;
28 aName: AnsiString=''): ITransaction; overload;
29 function StartTransaction(TPB: ITPB;
30 DefaultCompletion: TTransactionCompletion=taCommit;
31 aName: AnsiString=''): ITransaction; overload;
32
33 ITransaction
34 function GetTransactionName: AnsiString;
35 procedure SetTransactionName(aValue: AnsiString);
36
37 3. Additional Transaction information
38 ITPB.function AsText: AnsiString; {Returns TPB as a text string}
39
40 ITransaction
41 function GetDefaultCompletion: TTransactionCompletion;
42 function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
43
44 4. New IAttachment helper functions
45 function HasTable(aTableName: AnsiString): boolean;
46 function HasFunction(aFunctionName: AnsiString): boolean;
47 function HasProcedure(aProcName: AnsiString): boolean;
48 function GetAttachmentID: integer;
49 function GetCharSetID: integer;
50
51 5. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
52 will be allocted for batch operations.
53
54 6. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
55 function GetStatement: IStatement;
56 function GetTransaction: ITransaction;
57 function GetAttachment: IAttachment;
58
59 7. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
60 interfaces.
61
62 8. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
63 and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
64 functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
65 of numerics without loss of precision.
66
67 9. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
68
69 10. ISQLParams new method "Clear"
70
71 11. Support package fbudr added for support of User Defined Routines (UDRs).
72
73 12. Package layout changed with introduction of udr support. IB*.pas files moved from
74 root directory to "client".
75
76
77 FBINTF Change Log version (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
78
79 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
80
81 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
82 using remote protocol. Scrollable cursors with remote database expected to
83 be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
84 a not supported error.
85
86 3. IStatement: new function;
87 TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
88 TStatementFlags = set of TStatementFlag;
89 function GetFlags: TStatementFlags;
90
91 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
92 compatibility.
93 In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
94 type changes from ExecProcedure to Select. So that ExecuteQuery can continue
95 to be used with Update...Retruning statements that return a singleton row,
96 instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
97 it will open the cursor and return the first row only.
98
99 5. ITransaction: new functions:
100 function GetIsReadOnly: boolean;
101 function GetTransactionID: integer;
102 function GetTrInformation(Requests: array of byte): ITrInformation; overload;
103 function GetTrInformation(Request: byte): ITrInformation; overload;
104
105 The latter two return the Transaction Information block. The first two extract
106 information the Transaction Information block
107
108 6. New function TSQLTokeniser.ReadCharacters
109 Used internally.
110
111 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
112 parameter placeholders instead of named parameters.
113
114 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
115 transaction handle is now ignored if Rollback/Commit is called with Force=true
116
117 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
118 used to get an IBError Message instead of isc_interprete.
119
120 10. Internal tidyup. Native code now used for decoding integers and the events
121 buffer. Avoids dependencies on fbclient functions isc_portable_integer,
122 isc_event_block and isc_event_counts.
123
124 11. New IAttachment function
125 function GetAttachmentID: integer;
126
127 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
128 subclasses to enable UDR support.
129
130 FBINTF Change Log version (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
131
132 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
133
134 2. IStatement: new methods:
135 procedure SetStaleReferenceChecks(Enable:boolean); {default true}
136 function GetStaleReferenceChecks: boolean;
137
138 In previous versions, stale reference checks were always enabled. This allows the
139 user to disable them on a per statement basis. Note this can risk out-of-date
140 statement BLR. See User Guide.
141
142 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
143 stored procedure and hence avoids replacing named parameters within a containing
144 BEGIN..END block.
145
146 4. ISQLParam: using a string value to set an integer field with a scale factor of
147 zero is now treated as a special case to avoid the risk of floating point
148 rounding errors affecting pure integers.
149
150 5. ISQLParam: Review and tidy-up of SetAsString for numeric types.
151
152 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
153 SQL Parameter metadata (methods moved from ISQLParam).
154
155 7. ISQLParam: new method
156 function getColMetadata: IParamMetaData;
157 This instance of IParamMetaData returns the original column metadata which is unmutable.
158 Note: ISQLParam metadata can change after a parameter value has been set e.g when
159 setting a VARCHAR column to an integer value.
160
161 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
162 procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
163 also IAttachment:
164 function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
165 function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
166 function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
167 aSQLDialect: integer; GenerateParamNames: boolean=false;
168 CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
169 function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
170 GenerateParamNames: boolean=false;
171 CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
172
173 9. Support for scrollable cursors added. New/updated methods:
174 IAttachment:
175 function HasScollableCursors: boolean;
176 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
177 Scrollable: boolean=false): IResultSet; overload;
178 function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
179 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
180 params: array of const): IResultSet; overload;
181 function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
182 params: array of const): IResultSet; overload;
183 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
184 params: array of const): IResultSet; overload;
185 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
186 Scrollable: boolean=false): IResultSet; overload;
187 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
188 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
189 params: array of const): IResultSet; overload;
190 function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
191 function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
192 params: array of const): IResultSet; overload;
193 IStatement:
194 function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
195 IResultSet:
196 function FetchPrior: boolean; {fetch previous record}
197 function FetchFirst:boolean; {fetch first record}
198 function FetchLast: boolean; {fetch last record}
199 function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
200 function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
201 function IsBof: boolean;
202
203 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
204
205 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
206 may be noticeable when a line separator occurs inside quoted text. The quoted text
207 output by the tokeniser will now use the platform specific lineEnding regardless
208 of whether the input uses the CRLF or LF as a line separator.
209
210 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
211
212
213 FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
214
215 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
216
217 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
218 will now be encoded inline (i.e. as part of the parameter buffer) if they are
219 shorter than a pre-set limit. Longer values continue to be saved as blobs as a
220 separate server interaction. This is intended as a performance optimisation.
221
222 The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
223 IAttachment interface functions:
224
225 function GetInlineBlobLimit: integer;
226 procedure SetInlineBlobLimit(limit: integer);
227
228 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
229 user as the functionality is embedded in the implementation of the IStatement
230 interface. Three new functions are defined:
231
232 procedure AddToBatch;
233 function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
234 procedure CancelBatch;
235 function GetBatchCompletion: IBatchCompletion;
236 function GetBatchRowLimit: integer;
237 procedure SetBatchRowLimit(aLimit: integer);
238
239 Also
240
241 function IsInBatchMode: boolean; {true after call to execute(eaDefer)}
242 function HasBatchMode: boolean; {true if and only if IBatch Supported}
243
244 For more information see the User Guide.
245
246 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
247 provided with the EIBInterBaseError now include all three parts.
248
249 5. Firebird.pas and include files updated to Firebird 4.0.0
250
251 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
252 Returns SQL Statement type as a text string;
253
254 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
255 an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
256
257 FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
258
259 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
260 typo in FB30Statement.pas that caused an unknown parameter error.
261
262 FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
263
264 1. Imported (Firebird) constants updated for Firebird 4.
265
266 2. Firebird.pas from Firebird 4 integrated into source code tree.
267
268 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
269
270 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
271
272 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
273 QueryInterface may be used to coerce this interface from IFirebirdAPI. The
274 interface provides a single method "function GetIMasterIntf: IMaster". This provides
275 type safe access to the Firebird IMaster interface and avoids the need to turn
276 off object checks when coercing "function GetIMaster: TObject" to IMaster.
277
278 6. New IFirebirdAPI Calls:
279 function HasLocalTZDB: boolean;
280 function HasTimeZoneSupport: boolean;
281 function HasExtendedTZSupport: boolean;
282 procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
283 function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
284
285 7. New IAttachment Calls:
286 function HasDecFloatSupport: boolean;
287 function GetTimeZoneServices: ITimeZoneServices;
288 function HasTimeZoneSupport: boolean;
289
290 8. New Interface ITimeZoneServices.
291
292 9. New ISQLData API Calls:
293 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
294 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
295 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
296 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
297 function GetAsUTCDateTime: TDateTime;
298 function GetAsBCD: tBCD;
299
300 10. New ISQLParam API Calls
301 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
302 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
303 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
304 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
305 function GetAsUTCDateTime: TDateTime;
306 function GetAsBCD: tBCD;
307 function GetStatement: IStatement;
308 function GetTransaction: ITransaction;
309 procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
310 procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
311 procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
312 procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
313 procedure SetAsUTCDateTime(aUTCTime: TDateTime);
314 procedure SetAsBcd(aValue: tBCD);
315
316 11. New IArray API Calls
317 procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
318 procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
319 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
320 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
321 function GetAsUTCDateTime(index: array of integer): TDateTime;
322 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
323 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
324 procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
325 procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
326
327 12. Utility functions in IBUtils
328 function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
329 var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
330 procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
331 function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
332 function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
333 function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
334 function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
335
336 13. IDPB, ITPB and ISPB: new interface method
337 function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
338 This is used to add a parameter block item by the string equivalent of its
339 symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
340
341 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
342 function getParamTypeName: AnsiString;
343
344 15. fb_shutdown now called before unloading Firebird library. This can avoid a
345 SIGEVENT error when a programme using the embeded server is unloaded.
346
347 FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
348
349 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
350 with a Firebrid 3 client library.
351
352 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
353 If a client library path is not explicitly provided and the FIREBIRD environment
354 variable is set then the directory given by this variable and any 'lib' subdirectory
355 are searched for the Firebird client library. Only if none is found, is the default
356 client library used.
357
358 3. IUtil.FormatStatus now used to format error messages when using new API
359
360 4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
361
362 5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
363 returned using GetAsString and the string codepage is UTF8, the string is truncated so
364 that the byte length corresponds to the number of characters specified for the column.
365 SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
366 correct behaviour but may affect some implementations that relied upon automatic
367 trimming of trailing white space.
368
369 6. New IFirebirdAPI Calls:
370 function GetClientMajor: integer;
371 function GetClientMinor: integer;
372
373 7. IColumnMetaData and IArrayMetaData: new method
374 function GetCharSetWidth: integer;
375
376 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
377
378 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
379 case sensitive
380
381 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
382
383 3. New API Calls:
384 IColumnMetaData.GetStatement
385 IColumnMetaData.GetTransaction
386 ISQLData.GetStrDataLength
387 IResults.GetStatement
388 IAttachment.OpenBlob (using Blob metadata)
389 IAttachment.OpenArray (using array metadata)
390
391 4. FBMessages: removal of unused messages
392
393 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
394
395 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
396
397 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
398
399 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
400 where the second character of the parameter name is a numeric.
401
402 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
403 This returns the isc_version connection information as one or more lines.
404 This is the same information as returned by isql with the -z option.
405
406 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
407 is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
408 compiler option then the Firebird 3 API is no longer compiled in.
409
410 4. IColumnMetaData: new method.
411
412 TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
413 dfDateTime, {SQL DATETIME}
414 dfTime);
415
416 function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
417
418 This returns the max. number of characters returned by the "AsString" method
419 when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
420
421 5. Additional argument for IAttachment.PrepareWithNamedParameters -
422 CaseSensitiveParams: boolean = false
423
424 If this argument is set to true then SQL parameter names are assumed to be case
425 sensitive and must be referenced (using ISQLParams.ByName) using the case
426 sensitive name.
427
428 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
429 is of type VarChar or Char to set the parameter to a numeric value (e.g. using
430 .AsCurrency) and then subsequently to update the value to a non-numeric string
431 using .AsString.
432
433
434
435 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
436
437 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
438
439 2. Restrict IsMultiThread check to Unix only for compatibility with
440 https://bugs.freepascal.org/view.php?id=30535
441
442 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
443 named parameters and is intended to avoid problems with (e.g.) Execute Block
444 and processing internal parameters as statement parameters.
445
446 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
447 or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
448
449 5. New function added to IB.pas
450
451 function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
452
453 This allows a Firebird Library to be loaded from an explicit path. use the
454 IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
455 the library. It is possible to load Firebird libraries from different locations
456 simultaneously, each with a distinct IFirebirdAPI.

458 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
459
460 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
461 program compiled with -CR command line switch.
462
463 2. IServiceManager additions (informational):
464 function getProtocol: TProtocol;
465 function getPortNo: AnsiString;
466
467 3. IServiceManager improved error handling. Interfaces changed:
468 function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
469 function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
470 function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
471
472 4. IAttachment addition (informational)
473 function GetSecurityDatabase: AnsiString;
474
475 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
476 thus now returns accumulated stats for a select statement from opening a cursor
477 up to the last fetch.
478
479 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
480 the problem.
481
482 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
483 replaces deprecated "comp" type.
484
485 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
486
487 11. URL Connection Strings: inet4 and inet6 now recognised.
488
489 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
490
491 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
492
493
494 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
495
496 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
497
498 2. IAttachment: add two new methods
499 function HasDefaultCharSet: boolean;
500 function GetDefaultCharSetID: integer;
501
502 These return, respectively, true if a connection default character set was
503 specified and the character set id of the connection default character set.
504 The DefaultCharSetID is cached when the connection is opened and hence does not
505 require a database lookup.
506
507 3. Avoid exception when a text blob is a stored procedure parameter.
508
509 4. Update test suite to include a test for a stored proc returning a text blob.
510
511 5. IAttachment: add
512 function GetRemoteProtocol: AnsiString;
513 function GetODSMajorVersion: integer;
514 function GetODSMinorVersion: integer;
515 function GetAuthenticationMethod: AnsiString;
516
517 These results are cached when the connection is opened and hence do not
518 require a database lookup.
519
520 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
521 connect string used to create/connect to the database.
522
523 7. IAttachment: Create Database using SQL statement. The username and password
524 are now extracted and used to populate a DPB made available via IAttachment.getDPB.
525 It is now possible to use IAttachment disconnect/connect to reconnect to
526 a database for which the initial connection was established by a create
527 database sql statement. Available in FPC only.
528
529 8. Update Test 1 to test 5, 6 and 7 above.
530
531 9. IBUtils code tidy up.
532
533 10. Parameter Block interfaces "find" method. As documented, this should have
534 returned a nil interface when the item could not be found. Instead, an empty
535 interface item was returned. "Find" now works as documented and will return
536 a nil interface if the item cannot be found.
537
538 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
539
540 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
541 requests with additional parameters. This is to enable support for fb_info_page_contents
542 (return of page contents). Response to fb_info_page_contents returned as
543 a string with code page CP_NONE.
544
545 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
546 test suite updated.
547
548 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
549 a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
550
551 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
552 An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
553 default connection port to be specified.
554
555 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
556
557 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
558 Scale is no longer ignored.
559
560 2. Fix issues with setting SQL Param values using SetAsString with Date values
561 not in locale format but which are recognised by Firebird. Date values that
562 cannot be converted to a string using Pascal library are now passed through
563 to Firebird as Text Strings.
564
565 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
566 UTF8 and not UNICODE_FSS.
567
568 4. Charset ID problem. When using Firebird 3, with no default database character set
569 and a column has a non-default collation specified, an incorrect character set
570 id was being reported that could result in a 'division by zero' error when
571 used by IBX. This has now been fixed.
572
573 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
574 CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
575 the character sets supported can be updated on a per database basis. That is
576 it is possible to add a (Firebird) user defined character set to a database.
577
578 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
579 set supported by Firebird with the API.
580
581 7. Add missing isc_info_db_read_only to list of decoded Database Information items
582 in FBOutputBlock.pas and update test suite to include this item.
583
584 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
585
586 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
587 library or finding it by disk location, the PATH environment variable is now also set to
588 include the FIREBIRD directory. This is to ensure that the correct dlls in the
589 firebird client library dependencies are loaded.
590
591 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
592
593 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
594
595 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
596
597 13. FB30Statement: A check has been added to ensure that all SQL Parameters
598 have been given a value (including NULL). Previously, failing to set the
599 value of an SQL Parameter could give rise to unpredictable results or
600 an SQLDA error.
601
602 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
603
604 15. FBAttachment: Avoid string reference count error when processing an Ansistring
605 parameter in an array of const passed to IAttachment.OpenCursor, etc.
606
607 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
608 of const passed to IAttachment.OpenCursor, etc.
609
610
611 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
612
613 1. Change syntax to Mode Delphi
614
615 2. Change all uses of string type to explicit AnsiString in order to ensure
616 compatibility between Delphi and FPC.
617
618 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
619 defined for each interface.
620
621 4. Generics syntax variations for Delphi added
622
623 5. PChar replaced with PByte expect where an actual string is being referenced,
624 where PAnsiChar is used instead.
625
626 6. Review of type definitions in IBExternals to ensure Delphi compatibility
627
628 7. Testsuite updated for Delphi
629
630 FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
631
632 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
633 large blobs and the FB3 API.
634
635 2. Update Event Handling algorithm to avoid looping due to recreation of the
636 event block.
637
638 3. Avoid invalid XSQLDA error when the only parameter is updated to null
639
640 4. Array Handling: fix problem with text arrays with character set none. When the
641 DB connection has a default character set (e.g. UTF8), an error is raised by
642 Firebird if the space allocated is not enough to allow for transliteration, even
643 though it is not required for character set none.
644
645 5. IBUtils: List of reserved words brought up-to-date
646
647 6. Add ISQL style performance statistics collection to IStatement
648
649 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
650 CREATE DATABASE statement.
651
652 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
653 an array dimension is not mistaken for a named parameter prefix.
654
655 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
656 when Character set is octets. Avoids loss of non printable characters at start of string.
657
658 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
659 statistics for the last action. Requires use of procedure IStatement.EnableStatistics
660 to enable stats gathering.
661
662 11. API Version information added as constants to IB.pas
663
664 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
665
666 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
667
