1 FBINTF Change Log version (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +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 Note this can risk out-of-date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;
73
74 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
75
76 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
77 may be noticeable when a line separator occurs inside quoted text. The quoted text
78 output by the tokeniser will now use the platform specific lineEnding regardless
79 of whether the input uses the CRLF or LF as a line separator.
80
81 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
82
83
84 FBINTF Change Log version (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
85
86 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
87
88 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
89 will now be encoded inline (i.e. as part of the parameter buffer) if they are
90 shorter than a pre-set limit. Longer values continue to be saved as blobs as a
91 separate server interaction. This is intended as a performance optimisation.
92
93 The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
94 IAttachment interface functions:
95
96 function GetInlineBlobLimit: integer;
97 procedure SetInlineBlobLimit(limit: integer);
98
99 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
100 user as the functionality is embedded in the implementation of the IStatement
101 interface. Three new functions are defined:
102
103 procedure AddToBatch;
104 function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
105 procedure CancelBatch;
106 function GetBatchCompletion: IBatchCompletion;
107 function GetBatchRowLimit: integer;
108 procedure SetBatchRowLimit(aLimit: integer);
109
110 Also
111
112 function IsInBatchMode: boolean; {true after call to execute(eaDefer)}
113 function HasBatchMode: boolean; {true if and only if IBatch Supported}
114
115 For more information see the User Guide.
116
117 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
118 provided with the EIBInterBaseError now include all three parts.
119
120 5. Firebird.pas and include files updated to Firebird 4.0.0
121
122 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
123 Returns SQL Statement type as a text string;
124
125 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
126 an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
127
128 FBINTF Change Log version (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
129
130 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
131 typo in FB30Statement.pas that caused an unknown parameter error.
132
133 FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
134
135 1. Imported (Firebird) constants updated for Firebird 4.
136
137 2. Firebird.pas from Firebird 4 integrated into source code tree.
138
139 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
140
141 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
142
143 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
144 QueryInterface may be used to coerce this interface from IFirebirdAPI. The
145 interface provides a single method "function GetIMasterIntf: IMaster". This provides
146 type safe access to the Firebird IMaster interface and avoids the need to turn
147 off object checks when coercing "function GetIMaster: TObject" to IMaster.
148
149 6. New IFirebirdAPI Calls:
150 function HasLocalTZDB: boolean;
151 function HasTimeZoneSupport: boolean;
152 function HasExtendedTZSupport: boolean;
153 procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
154 function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
155
156 7. New IAttachment Calls:
157 function HasDecFloatSupport: boolean;
158 function GetTimeZoneServices: ITimeZoneServices;
159 function HasTimeZoneSupport: boolean;
160
161 8. New Interface ITimeZoneServices.
162

167 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
168 function GetAsUTCDateTime: TDateTime;
169 function GetAsBCD: tBCD;
170
171 10. New ISQLParam API Calls
172 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
173 procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
174 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
175 procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;

184 procedure SetAsUTCDateTime(aUTCTime: TDateTime);
185 procedure SetAsBcd(aValue: tBCD);
186
187 11. New IArray API Calls
188 procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
189 procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
190 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
191 procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
192 function GetAsUTCDateTime(index: array of integer): TDateTime;
193 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
194 procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;

196 procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
197
198 12. Utility functions in IBUtils
199 function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
200 var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
201 procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
202 function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
203 function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
204 function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
205 function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
206
207 13. IDPB, ITPB and ISPB: new interface method
208 function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
209 This is used to add a parameter block item by the string equivalent of its
210 symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
211
212 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
213 function getParamTypeName: AnsiString;
214
215 15. fb_shutdown now called before unloading Firebird library. This can avoid a
216 SIGEVENT error when a programme using the embeded server is unloaded.
217
218 FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
219
220 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
221 with a Firebrid 3 client library.
222
223 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
224 If a client library path is not explicitly provided and the FIREBIRD environment
225 variable is set then the directory given by this variable and any 'lib' subdirectory
226 are searched for the Firebird client library. Only if none is found, is the default
227 client library used.
228
229 3. IUtil.FormatStatus now used to format error messages when using new API
230
231 4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
232
233 5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
234 returned using GetAsString and the string codepage is UTF8, the string is truncated so
235 that the byte length corresponds to the number of characters specified for the column.
236 SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
237 correct behaviour but may affect some implementations that relied upon automatic
238 trimming of trailing white space.
239
240 6. New IFirebirdAPI Calls:
241 function GetClientMajor: integer;
242 function GetClientMinor: integer;
243
244 7. IColumnMetaData and IArrayMetaData: new method
245 function GetCharSetWidth: integer;
246
247 FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
248
249 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
250 case sensitive
251
252 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
253
254 3. New API Calls:
255 IColumnMetaData.GetStatement
256 IColumnMetaData.GetTransaction
257 ISQLData.GetStrDataLength
258 IResults.GetStatement
259 IAttachment.OpenBlob (using Blob metadata)
260 IAttachment.OpenArray (using array metadata)
261
262 4. FBMessages: removal of unused messages
263
264 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
265
266 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
267
268 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
269
270 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
271 where the second character of the parameter name is a numeric.
272
273 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
274 This returns the isc_version connection information as one or more lines.
275 This is the same information as returned by isql with the -z option.
276
277 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
278 is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
279 compiler option then the Firebird 3 API is no longer compiled in.
280
281 4. IColumnMetaData: new method.
282
283 TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
284 dfDateTime, {SQL DATETIME}
285 dfTime);
286
287 function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
288
289 This returns the max. number of characters returned by the "AsString" method
290 when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
291
292 5. Additional argument for IAttachment.PrepareWithNamedParameters -
293 CaseSensitiveParams: boolean = false
294
295 If this argument is set to true then SQL parameter names are assumed to be case
296 sensitive and must be referenced (using ISQLParams.ByName) using the case
297 sensitive name.
298
299 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
300 is of type VarChar or Char to set the parameter to a numeric value (e.g. using
301 .AsCurrency) and then subsequently to update the value to a non-numeric string
302 using .AsString.
303
304
305
306 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
307
308 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
309
310 2. Restrict IsMultiThread check to Unix only for compatibility with
311 https://bugs.freepascal.org/view.php?id=30535
312
313 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
314 named parameters and is intended to avoid problems with (e.g.) Execute Block
315 and processing internal parameters as statement parameters.
316
317 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
318 or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
319
320 5. New function added to IB.pas
321
322 function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
323
324 This allows a Firebird Library to be loaded from an explicit path. use the
325 IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
326 the library. It is possible to load Firebird libraries from different locations
327 simultaneously, each with a distinct IFirebirdAPI.
328
329 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
330
331 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
332 program compiled with -CR command line switch.
333
334 2. IServiceManager additions (informational):
335 function getProtocol: TProtocol;
336 function getPortNo: AnsiString;
337
338 3. IServiceManager improved error handling. Interfaces changed:
339 function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
340 function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
341 function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
342
343 4. IAttachment addition (informational)
344 function GetSecurityDatabase: AnsiString;
345
346 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
347 thus now returns accumulated stats for a select statement from opening a cursor
348 up to the last fetch.
349
350 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
351 the problem.
352
353 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
354 replaces deprecated "comp" type.
355
356 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
357
358 11. URL Connection Strings: inet4 and inet6 now recognised.
359
360 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
361
362 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
363
364
365 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
366
367 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
368
369 2. IAttachment: add two new methods
370 function HasDefaultCharSet: boolean;
371 function GetDefaultCharSetID: integer;
372
373 These return, respectively, true if a connection default character set was
374 specified and the character set id of the connection default character set.
375 The DefaultCharSetID is cached when the connection is opened and hence does not
376 require a database lookup.
377
378 3. Avoid exception when a text blob is a stored procedure parameter.
379
380 4. Update test suite to include a test for a stored proc returning a text blob.
381
382 5. IAttachment: add
383 function GetRemoteProtocol: AnsiString;
384 function GetODSMajorVersion: integer;
385 function GetODSMinorVersion: integer;
386 function GetAuthenticationMethod: AnsiString;
387
388 These results are cached when the connection is opened and hence do not
389 require a database lookup.
390
391 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
392 connect string used to create/connect to the database.
393
394 7. IAttachment: Create Database using SQL statement. The username and password
395 are now extracted and used to populate a DPB made available via IAttachment.getDPB.
396 It is now possible to use IAttachment disconnect/connect to reconnect to
397 a database for which the initial connection was established by a create
398 database sql statement. Available in FPC only.
399
400 8. Update Test 1 to test 5, 6 and 7 above.
401
402 9. IBUtils code tidy up.
403
404 10. Parameter Block interfaces "find" method. As documented, this should have
405 returned a nil interface when the item could not be found. Instead, an empty
406 interface item was returned. "Find" now works as documented and will return
407 a nil interface if the item cannot be found.
408
409 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
410
411 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
412 requests with additional parameters. This is to enable support for fb_info_page_contents
413 (return of page contents). Response to fb_info_page_contents returned as
414 a string with code page CP_NONE.
415
416 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
417 test suite updated.
418
419 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
420 a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
421
422 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
423 An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
424 default connection port to be specified.
425
426 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
427
428 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
429 Scale is no longer ignored.
430
431 2. Fix issues with setting SQL Param values using SetAsString with Date values
432 not in locale format but which are recognised by Firebird. Date values that
433 cannot be converted to a string using Pascal library are now passed through
434 to Firebird as Text Strings.
435
436 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
437 UTF8 and not UNICODE_FSS.
438
439 4. Charset ID problem. When using Firebird 3, with no default database character set
440 and a column has a non-default collation specified, an incorrect character set
441 id was being reported that could result in a 'division by zero' error when
442 used by IBX. This has now been fixed.
443
444 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
445 CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
446 the character sets supported can be updated on a per database basis. That is
447 it is possible to add a (Firebird) user defined character set to a database.
448
449 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
450 set supported by Firebird with the API.
451
452 7. Add missing isc_info_db_read_only to list of decoded Database Information items
453 in FBOutputBlock.pas and update test suite to include this item.
454
455 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
456
457 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
458 library or finding it by disk location, the PATH environment variable is now also set to
459 include the FIREBIRD directory. This is to ensure that the correct dlls in the
460 firebird client library dependencies are loaded.
461
462 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
463
464 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
465
466 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
467
468 13. FB30Statement: A check has been added to ensure that all SQL Parameters
469 have been given a value (including NULL). Previously, failing to set the
470 value of an SQL Parameter could give rise to unpredictable results or
471 an SQLDA error.
472
473 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
474
475 15. FBAttachment: Avoid string reference count error when processing an Ansistring
476 parameter in an array of const passed to IAttachment.OpenCursor, etc.
477
478 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
479 of const passed to IAttachment.OpenCursor, etc.

482 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
483
484 1. Change syntax to Mode Delphi
485
486 2. Change all uses of string type to explicit AnsiString in order to ensure
487 compatibility between Delphi and FPC.
488
489 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
490 defined for each interface.
491
492 4. Generics syntax variations for Delphi added
493
494 5. PChar replaced with PByte expect where an actual string is being referenced,
495 where PAnsiChar is used instead.
496
497 6. Review of type definitions in IBExternals to ensure Delphi compatibility
498
499 7. Testsuite updated for Delphi

501 FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
502
503 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
504 large blobs and the FB3 API.
505
506 2. Update Event Handling algorithm to avoid looping due to recreation of the
507 event block.
508
509 3. Avoid invalid XSQLDA error when the only parameter is updated to null
510
511 4. Array Handling: fix problem with text arrays with character set none. When the
512 DB connection has a default character set (e.g. UTF8), an error is raised by
513 Firebird if the space allocated is not enough to allow for transliteration, even
514 though it is not required for character set none.
515
516 5. IBUtils: List of reserved words brought up-to-date
517
518 6. Add ISQL style performance statistics collection to IStatement
519
520 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
521 CREATE DATABASE statement.
522
523 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
524 an array dimension is not mistaken for a named parameter prefix.
525
526 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
527 when Character set is octets. Avoids loss of non printable characters at start of string.
528
529 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
530 statistics for the last action. Requires use of procedure IStatement.EnableStatistics
531 to enable stats gathering.
532
533 11. API Version information added as constants to IB.pas
534
535 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
536
537 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
