1 FBINTF Change Log version (1.3-2 Build 12850) Wed, 20 Oct 2021 15:12:15 +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 Note this can risk out-of-date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 IFirebirdAPI:
46 function HasScollableCursors: boolean;
47 IAttachment:
48 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
49 Scrollable: boolean=false): IResultSet; overload;
50 function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
51 function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
52 params: array of const): IResultSet; overload;
53 function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
54 params: array of const): IResultSet; overload;
55 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
56 params: array of const): IResultSet; overload;
57 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
58 Scrollable: boolean=false): IResultSet; overload;
59 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
60 function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
61 params: array of const): IResultSet; overload;
62 function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
63 function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
64 params: array of const): IResultSet; overload;
65 IStatement:
66 function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
67 IResultSet:
68 function FetchPrior: boolean; {fetch previous record}
69 function FetchFirst:boolean; {fetch first record}
70 function FetchLast: boolean; {fetch last record}
71 function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
72 function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
73 function IsBof: boolean;

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

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