1 FBINTF Change Log version (1.3-2 Build 12860) Thu, 21 Oct 2021 13:16:09 +0100
2
3 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
4
5 2. IStatement: new methods:
6 procedure SetStaleReferenceChecks(Enable:boolean); {default true}
7 function GetStaleReferenceChecks: boolean;
8
9 In previous versions, stale reference checks were always enabled. This allows the
10 user to disable them on a per statement basis. Note this can risk out-of-date
11 statement BLR. See User Guide.
12
13 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
14 stored procedure and hence avoids replacing named parameters within a containing
15 BEGIN..END block.
16
17 4. ISQLParam: using a string value to set an integer field with a scale factor of
18 zero is now treated as a special case to avoid the risk of floating point
19 rounding errors affecting pure integers.
20
21 5. ISQLParam: Review and tidy-up of SetAsString for numeric types.
22
23 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
24 SQL Parameter metadata (methods moved from ISQLParam).
25
26 7. ISQLParam: new method
27 function getColMetadata: IParamMetaData;
28 This instance of IParamMetaData returns the original column metadata which is unmutable.
29 Note: ISQLParam metadata can change after a parameter value has been set e.g when
30 setting a VARCHAR column to an integer value.
31
32 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
33 procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
34 also IAttachment:
35 function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
36 function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
37 function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
38 aSQLDialect: integer; GenerateParamNames: boolean=false;
39 CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
40 function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
41 GenerateParamNames: boolean=false;
42 CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
43
44 9. Support for scrollable cursors added. New/updated methods:
45 IAttachment:
46 function HasScollableCursors: boolean;
47 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
48 Scrollable: boolean=false): IResultSet; overload;
49 function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
50 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
51 params: array of const): IResultSet; overload;
52 function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
53 params: array of const): IResultSet; overload;
54 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
55 params: array of const): IResultSet; overload;
56 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
57 Scrollable: boolean=false): IResultSet; overload;
58 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
59 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
60 params: array of const): IResultSet; overload;
61 function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
62 function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
63 params: array of const): IResultSet; overload;
64 IStatement:
65 function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
66 IResultSet:
67 function FetchPrior: boolean; {fetch previous record}
68 function FetchFirst:boolean; {fetch first record}
69 function FetchLast: boolean; {fetch last record}
70 function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
71 function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
72 function IsBof: boolean;

76 FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
77
78 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
79
80 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
81 will now be encoded inline (i.e. as part of the parameter buffer) if they are
82 shorter than a pre-set limit. Longer values continue to be saved as blobs as a
83 separate server interaction. This is intended as a performance optimisation.
84
85 The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
86 IAttachment interface functions:
87
88 function GetInlineBlobLimit: integer;
89 procedure SetInlineBlobLimit(limit: integer);
90
91 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
92 user as the functionality is embedded in the implementation of the IStatement
93 interface. Three new functions are defined:
94
95 procedure AddToBatch;
96 function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
97 procedure CancelBatch;
98 function GetBatchCompletion: IBatchCompletion;
99 function GetBatchRowLimit: integer;
100 procedure SetBatchRowLimit(aLimit: integer);
101
102 Also
103
104 function IsInBatchMode: boolean; {true after call to execute(eaDefer)}
105 function HasBatchMode: boolean; {true if and only if IBatch Supported}
106
107 For more information see the User Guide.
108
109 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
110 provided with the EIBInterBaseError now include all three parts.
111
112 5. Firebird.pas and include files updated to Firebird 4.0.0
113
114 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
115 Returns SQL Statement type as a text string;
116
117 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
118 an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
119
120 FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
121
122 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
123 typo in FB30Statement.pas that caused an unknown parameter error.
124
125 FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
126
127 1. Imported (Firebird) constants updated for Firebird 4.
128
129 2. Firebird.pas from Firebird 4 integrated into source code tree.
130
131 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
132
133 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
134
135 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
136 QueryInterface may be used to coerce this interface from IFirebirdAPI. The
137 interface provides a single method "function GetIMasterIntf: IMaster". This provides
138 type safe access to the Firebird IMaster interface and avoids the need to turn
139 off object checks when coercing "function GetIMaster: TObject" to IMaster.
140
141 6. New IFirebirdAPI Calls:
142 function HasLocalTZDB: boolean;
143 function HasTimeZoneSupport: boolean;
144 function HasExtendedTZSupport: boolean;
145 procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
146 function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
147
148 7. New IAttachment Calls:
149 function HasDecFloatSupport: boolean;
150 function GetTimeZoneServices: ITimeZoneServices;
151 function HasTimeZoneSupport: boolean;
152
153 8. New Interface ITimeZoneServices.
154
155 9. New ISQLData API Calls:
156 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
157 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
158 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
159 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
160 function GetAsUTCDateTime: TDateTime;
161 function GetAsBCD: tBCD;
162
163 10. New ISQLParam API Calls
164 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
165 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
166 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
167 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
168 function GetAsUTCDateTime: TDateTime;
169 function GetAsBCD: tBCD;
170 function GetStatement: IStatement;
171 function GetTransaction: ITransaction;
172 procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
173 procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
174 procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
175 procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
176 procedure SetAsUTCDateTime(aUTCTime: TDateTime);
177 procedure SetAsBcd(aValue: tBCD);
178
179 11. New IArray API Calls
180 procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
181 procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
182 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
183 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
184 function GetAsUTCDateTime(index: array of integer): TDateTime;
185 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
186 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
187 procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
188 procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
189
190 12. Utility functions in IBUtils
191 function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
192 var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
193 procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
194 function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
195 function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
196 function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
197 function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
198
199 13. IDPB, ITPB and ISPB: new interface method
200 function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
201 This is used to add a parameter block item by the string equivalent of its
202 symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
203
204 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
205 function getParamTypeName: AnsiString;
206
207 15. fb_shutdown now called before unloading Firebird library. This can avoid a
208 SIGEVENT error when a programme using the embeded server is unloaded.
209
210 FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
211
212 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
213 with a Firebrid 3 client library.
214
215 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
216 If a client library path is not explicitly provided and the FIREBIRD environment
217 variable is set then the directory given by this variable and any 'lib' subdirectory
218 are searched for the Firebird client library. Only if none is found, is the default
219 client library used.
220
221 3. IUtil.FormatStatus now used to format error messages when using new API
222
223 4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
224
225 5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
226 returned using GetAsString and the string codepage is UTF8, the string is truncated so
227 that the byte length corresponds to the number of characters specified for the column.
228 SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
229 correct behaviour but may affect some implementations that relied upon automatic
230 trimming of trailing white space.
231
232 6. New IFirebirdAPI Calls:
233 function GetClientMajor: integer;
234 function GetClientMinor: integer;
235
236 7. IColumnMetaData and IArrayMetaData: new method
237 function GetCharSetWidth: integer;
238
239 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
240
241 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
242 case sensitive
243
244 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
245
246 3. New API Calls:
247 IColumnMetaData.GetStatement
248 IColumnMetaData.GetTransaction
249 ISQLData.GetStrDataLength
250 IResults.GetStatement
251 IAttachment.OpenBlob (using Blob metadata)
252 IAttachment.OpenArray (using array metadata)
253
254 4. FBMessages: removal of unused messages
255
256 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
257
258 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
259
260 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
261
262 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
263 where the second character of the parameter name is a numeric.
264
265 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
266 This returns the isc_version connection information as one or more lines.
267 This is the same information as returned by isql with the -z option.
268
269 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
270 is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
271 compiler option then the Firebird 3 API is no longer compiled in.
272
273 4. IColumnMetaData: new method.
274
275 TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
276 dfDateTime, {SQL DATETIME}
277 dfTime);
278
279 function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
280
281 This returns the max. number of characters returned by the "AsString" method
282 when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
283
284 5. Additional argument for IAttachment.PrepareWithNamedParameters -
285 CaseSensitiveParams: boolean = false
286
287 If this argument is set to true then SQL parameter names are assumed to be case
288 sensitive and must be referenced (using ISQLParams.ByName) using the case
289 sensitive name.
290
291 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
292 is of type VarChar or Char to set the parameter to a numeric value (e.g. using
293 .AsCurrency) and then subsequently to update the value to a non-numeric string
294 using .AsString.
295
296
297
298 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
299
300 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
301
302 2. Restrict IsMultiThread check to Unix only for compatibility with
303 https://bugs.freepascal.org/view.php?id=30535
304
305 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
306 named parameters and is intended to avoid problems with (e.g.) Execute Block
307 and processing internal parameters as statement parameters.
308
309 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
310 or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
311
312 5. New function added to IB.pas
313
314 function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
315
316 This allows a Firebird Library to be loaded from an explicit path. use the
317 IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
318 the library. It is possible to load Firebird libraries from different locations
319 simultaneously, each with a distinct IFirebirdAPI.
320
321 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
322
323 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
324 program compiled with -CR command line switch.
325
326 2. IServiceManager additions (informational):
327 function getProtocol: TProtocol;
328 function getPortNo: AnsiString;
329
330 3. IServiceManager improved error handling. Interfaces changed:
331 function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
332 function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
333 function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
334
335 4. IAttachment addition (informational)
336 function GetSecurityDatabase: AnsiString;
337
338 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
339 thus now returns accumulated stats for a select statement from opening a cursor
340 up to the last fetch.
341
342 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
343 the problem.
344
345 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
346 replaces deprecated "comp" type.
347
348 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
349
350 11. URL Connection Strings: inet4 and inet6 now recognised.
351
352 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
353
354 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
355
356
357 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
358
359 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
360
361 2. IAttachment: add two new methods
362 function HasDefaultCharSet: boolean;
363 function GetDefaultCharSetID: integer;
364
365 These return, respectively, true if a connection default character set was
366 specified and the character set id of the connection default character set.
367 The DefaultCharSetID is cached when the connection is opened and hence does not
368 require a database lookup.
369
370 3. Avoid exception when a text blob is a stored procedure parameter.
371
372 4. Update test suite to include a test for a stored proc returning a text blob.
373
374 5. IAttachment: add
375 function GetRemoteProtocol: AnsiString;
376 function GetODSMajorVersion: integer;
377 function GetODSMinorVersion: integer;
378 function GetAuthenticationMethod: AnsiString;
379
380 These results are cached when the connection is opened and hence do not
381 require a database lookup.
382
383 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
384 connect string used to create/connect to the database.
385
386 7. IAttachment: Create Database using SQL statement. The username and password
387 are now extracted and used to populate a DPB made available via IAttachment.getDPB.
388 It is now possible to use IAttachment disconnect/connect to reconnect to
389 a database for which the initial connection was established by a create
390 database sql statement. Available in FPC only.
391
392 8. Update Test 1 to test 5, 6 and 7 above.
393
394 9. IBUtils code tidy up.
395
396 10. Parameter Block interfaces "find" method. As documented, this should have
397 returned a nil interface when the item could not be found. Instead, an empty
398 interface item was returned. "Find" now works as documented and will return
399 a nil interface if the item cannot be found.
400
401 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
402
403 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
404 requests with additional parameters. This is to enable support for fb_info_page_contents
405 (return of page contents). Response to fb_info_page_contents returned as
406 a string with code page CP_NONE.
407
408 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
409 test suite updated.
410
411 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
412 a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
413
414 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
415 An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
416 default connection port to be specified.
417
418 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
419
420 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
421 Scale is no longer ignored.
422
423 2. Fix issues with setting SQL Param values using SetAsString with Date values
424 not in locale format but which are recognised by Firebird. Date values that
425 cannot be converted to a string using Pascal library are now passed through
426 to Firebird as Text Strings.
427
428 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
429 UTF8 and not UNICODE_FSS.
430
431 4. Charset ID problem. When using Firebird 3, with no default database character set
432 and a column has a non-default collation specified, an incorrect character set
433 id was being reported that could result in a 'division by zero' error when
434 used by IBX. This has now been fixed.
435
436 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
437 CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
438 the character sets supported can be updated on a per database basis. That is
439 it is possible to add a (Firebird) user defined character set to a database.
440
441 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
442 set supported by Firebird with the API.
443
444 7. Add missing isc_info_db_read_only to list of decoded Database Information items
445 in FBOutputBlock.pas and update test suite to include this item.
446
447 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
448
449 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
450 library or finding it by disk location, the PATH environment variable is now also set to
451 include the FIREBIRD directory. This is to ensure that the correct dlls in the
452 firebird client library dependencies are loaded.
453
454 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
455
456 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
457
458 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
459
460 13. FB30Statement: A check has been added to ensure that all SQL Parameters
461 have been given a value (including NULL). Previously, failing to set the
462 value of an SQL Parameter could give rise to unpredictable results or
463 an SQLDA error.
464
465 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
466
467 15. FBAttachment: Avoid string reference count error when processing an Ansistring
468 parameter in an array of const passed to IAttachment.OpenCursor, etc.
469
470 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
471 of const passed to IAttachment.OpenCursor, etc.

474 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
475
476 1. Change syntax to Mode Delphi
477
478 2. Change all uses of string type to explicit AnsiString in order to ensure
479 compatibility between Delphi and FPC.
480
481 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
482 defined for each interface.
483
484 4. Generics syntax variations for Delphi added
485
486 5. PChar replaced with PByte expect where an actual string is being referenced,
487 where PAnsiChar is used instead.
488
489 6. Review of type definitions in IBExternals to ensure Delphi compatibility
490
491 7. Testsuite updated for Delphi
492
493 FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
494
495 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
496 large blobs and the FB3 API.
497
498 2. Update Event Handling algorithm to avoid looping due to recreation of the
499 event block.
500
501 3. Avoid invalid XSQLDA error when the only parameter is updated to null
502
503 4. Array Handling: fix problem with text arrays with character set none. When the
504 DB connection has a default character set (e.g. UTF8), an error is raised by
505 Firebird if the space allocated is not enough to allow for transliteration, even
506 though it is not required for character set none.
507
508 5. IBUtils: List of reserved words brought up-to-date
509
510 6. Add ISQL style performance statistics collection to IStatement
511
512 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
513 CREATE DATABASE statement.
514
515 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
516 an array dimension is not mistaken for a named parameter prefix.
517
518 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
519 when Character set is octets. Avoids loss of non printable characters at start of string.
520
521 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
522 statistics for the last action. Requires use of procedure IStatement.EnableStatistics
523 to enable stats gathering.
524
525 11. API Version information added as constants to IB.pas
526
527 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
528
529 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
