|
3 |
1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a |
4 |
typo in FB30Statement.pas that caused an unknown parameter error. |

FBINTF Change Log version (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000 |
7 |
|
8 |
1. Imported (Firebird) constants updated for Firebird 4. |
9 |
|
10 |
2. Firebird.pas from Firebird 4 integrated into source code tree. |
11 |
|
12 |
3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types. |
13 |
|
14 |
4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision. |
15 |
|
16 |
5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider. |
17 |
QueryInterface may be used to coerce this interface from IFirebirdAPI. The |
18 |
interface provides a single method "function GetIMasterIntf: IMaster". This provides |
19 |
type safe access to the Firebird IMaster interface and avoids the need to turn |
20 |
off object checks when coercing "function GetIMaster: TObject" to IMaster. |
21 |
|
22 |
6. New IFirebirdAPI Calls: |
23 |
function HasLocalTZDB: boolean; |

28 |
|
29 |
7. New IAttachment Calls: |
30 |

56 |
procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload; |
57 |
procedure SetAsUTCDateTime(aUTCTime: TDateTime); |
58 |
procedure SetAsBcd(aValue: tBCD); |
59 |
|
60 |
11. New IArray API Calls |
61 |
procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload; |
62 |
procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload; |

70 |
|
71 |
12. Utility functions in IBUtils |
72 |
function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime; |
73 |
var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean; |
74 |

79 |
|
80 |
13. IDPB, ITPB and ISPB: new interface method |
81 |
function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem; |
82 |
This is used to add a parameter block item by the string equivalent of its |
83 |
symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...' |
84 |
|
85 |
14. IDPBItem/ITPBItem/ISPBItem: new interface method: |
86 |
function getParamTypeName: AnsiString; |
87 |
|
88 |
15. fb_shutdown now called before unloading Firebird library. This can avoid a |
89 |
SIGEVENT error when a programme using the embeded server is unloaded. |
90 |
|
91 |
FBINTF Change Log version (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100 |
92 |
|
93 |
1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API |
94 |
with a Firebrid 3 client library. |
95 |
|
96 |
2. Linux Only: FIREBIRD environment variable is now checked when loading the client library. |
97 |
If a client library path is not explicitly provided and the FIREBIRD environment |
98 |
variable is set then the directory given by this variable and any 'lib' subdirectory |
99 |
are searched for the Firebird client library. Only if none is found, is the default |
100 |
client library used. |
101 |
|
102 |
3. IUtil.FormatStatus now used to format error messages when using new API |
103 |
|
104 |
4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer. |
105 |
|
106 |
5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is |
107 |
returned using GetAsString and the string codepage is UTF8, the string is truncated so |
108 |
that the byte length corresponds to the number of characters specified for the column. |
109 |
SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is |
110 |
correct behaviour but may affect some implementations that relied upon automatic |
111 |
trimming of trailing white space. |
112 |
|
113 |
6. New IFirebirdAPI Calls: |
114 |
function GetClientMajor: integer; |
115 |
function GetClientMinor: integer; |
116 |
|
117 |
7. IColumnMetaData and IArrayMetaData: new method |
118 |
function GetCharSetWidth: integer; |
119 |
|
120 |
FBINTF Change Log version (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100 |
121 |
|
122 |
1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are |
123 |
case sensitive |
124 |
|
125 |
2. Single line SQL comments starting with '--' are now recognised by SQL Parser. |
126 |
|
127 |
3. New API Calls: |
128 |
IColumnMetaData.GetStatement |
129 |
IColumnMetaData.GetTransaction |
130 |
ISQLData.GetStrDataLength |
131 |
IResults.GetStatement |
132 |
IAttachment.OpenBlob (using Blob metadata) |
133 |
IAttachment.OpenArray (using array metadata) |
134 |
|
135 |
4. FBMessages: removal of unused messages |
136 |
|
137 |
5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set. |
138 |
|
139 |
6. TIBSQLStatementType: SQLSavePoint added to end of enumeration. |
140 |
|
141 |
FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000 |
142 |
|
143 |
1. Fix a problem with the SQL parameter parser that failed to recognise parameters |
144 |
where the second character of the parameter name is a numeric. |
145 |
|
146 |
2. New method for IAttachment: procedure getFBVersion(version: TStrings); |
147 |
This returns the isc_version connection information as one or more lines. |
148 |
This is the same information as returned by isql with the -z option. |
149 |
|
150 |
3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API |
151 |
is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a |
152 |
compiler option then the Firebird 3 API is no longer compiled in. |
153 |
|
154 |
4. IColumnMetaData: new method. |
155 |
|
156 |
TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP} |
157 |
dfDateTime, {SQL DATETIME} |
158 |
dfTime); |
159 |
|
160 |
function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer; |
161 |
|
162 |
This returns the max. number of characters returned by the "AsString" method |
163 |
when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME. |
164 |
|
165 |
5. Additional argument for IAttachment.PrepareWithNamedParameters - |
166 |
CaseSensitiveParams: boolean = false |
167 |
|
168 |
If this argument is set to true then SQL parameter names are assumed to be case |
169 |
sensitive and must be referenced (using ISQLParams.ByName) using the case |
170 |
sensitive name. |
171 |
|
172 |
6. Bug fix: when setting a query parameter, it is now possible, when the parameter |
173 |
is of type VarChar or Char to set the parameter to a numeric value (e.g. using |
174 |
.AsCurrency) and then subsequently to update the value to a non-numeric string |
175 |
using .AsString. |
176 |
|
177 |
|
178 |
|
179 |
FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000 |
180 |
|
181 |
1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary |
182 |
|
183 |
2. Restrict IsMultiThread check to Unix only for compatibility with |
184 |
https://bugs.freepascal.org/view.php?id=30535 |
185 |
|
186 |
3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with |
187 |
named parameters and is intended to avoid problems with (e.g.) Execute Block |
188 |
and processing internal parameters as statement parameters. |
189 |
|
190 |
4. New interface IFirebirdLibrary provides access to the underlying firebird DLL |
191 |
or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI. |
192 |
|
193 |
5. New function added to IB.pas |
194 |
|
195 |
function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary |
196 |
|
197 |
This allows a Firebird Library to be loaded from an explicit path. use the |
198 |
IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using |
199 |
the library. It is possible to load Firebird libraries from different locations |
200 |
simultaneously, each with a distinct IFirebirdAPI. |
201 |
|
202 |
FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100 |
203 |
|
204 |
1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when |
205 |
program compiled with -CR command line switch. |
206 |
|
207 |
2. IServiceManager additions (informational): |
208 |
function getProtocol: TProtocol; |
209 |
function getPortNo: AnsiString; |
210 |
|
211 |
3. IServiceManager improved error handling. Interfaces changed: |
212 |
function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean; |
213 |
function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; |
214 |
function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload; |
215 |
|
216 |
4. IAttachment addition (informational) |
217 |
function GetSecurityDatabase: AnsiString; |
218 |
|
219 |
5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics |
220 |
thus now returns accumulated stats for a select statement from opening a cursor |
221 |
up to the last fetch. |
222 |
|
223 |
6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting |
224 |
the problem. |
225 |
|
226 |
7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64" |
227 |
replaces deprecated "comp" type. |
228 |
|
229 |
10. Testsuite Test10 updated to include thread synchronisation for event reporting. |
230 |
|
231 |
11. URL Connection Strings: inet4 and inet6 now recognised. |
232 |
|
233 |
12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax. |
234 |
|
235 |
13. IAttachment.CharSetName2CharSetID is now performed case insensitive. |
236 |
|
237 |
|
238 |
FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000 |
239 |
|
240 |
1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character. |
241 |
|
242 |
2. IAttachment: add two new methods |
243 |
function HasDefaultCharSet: boolean; |
244 |
function GetDefaultCharSetID: integer; |
245 |
|
246 |
These return, respectively, true if a connection default character set was |
247 |
specified and the character set id of the connection default character set. |
248 |
The DefaultCharSetID is cached when the connection is opened and hence does not |
249 |
require a database lookup. |
250 |
|
251 |
3. Avoid exception when a text blob is a stored procedure parameter. |
252 |
|
253 |
4. Update test suite to include a test for a stored proc returning a text blob. |
254 |
|
255 |
5. IAttachment: add |
256 |
function GetRemoteProtocol: AnsiString; |
257 |
function GetODSMajorVersion: integer; |
258 |
function GetODSMinorVersion: integer; |
259 |
function GetAuthenticationMethod: AnsiString; |
260 |
|
261 |
These results are cached when the connection is opened and hence do not |
262 |
require a database lookup. |
263 |
|
264 |
6. IAttachment: add "function GetConnectString: AnsiString;" This returns the |
265 |
connect string used to create/connect to the database. |
266 |
|
267 |
7. IAttachment: Create Database using SQL statement. The username and password |
268 |
are now extracted and used to populate a DPB made available via IAttachment.getDPB. |
269 |
It is now possible to use IAttachment disconnect/connect to reconnect to |
270 |
a database for which the initial connection was established by a create |
271 |
database sql statement. Available in FPC only. |
272 |
|
273 |
8. Update Test 1 to test 5, 6 and 7 above. |
274 |
|
275 |
9. IBUtils code tidy up. |
276 |
|
277 |
10. Parameter Block interfaces "find" method. As documented, this should have |
278 |
returned a nil interface when the item could not be found. Instead, an empty |
279 |
interface item was returned. "Find" now works as documented and will return |
280 |
a nil interface if the item cannot be found. |
281 |
|
282 |
11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date. |
283 |
|
284 |
12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information |
285 |
requests with additional parameters. This is to enable support for fb_info_page_contents |
286 |
(return of page contents). Response to fb_info_page_contents returned as |
287 |
a string with code page CP_NONE. |
288 |
|
289 |
13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus |
290 |
test suite updated. |
291 |
|
292 |
14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as |
293 |
a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type. |
294 |
|
295 |
15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet. |
296 |
An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non |
297 |
default connection port to be specified. |
298 |
|
299 |
FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000 |
300 |
|
301 |
1. Fix issues with setting SQL Param values using SetAsString with Numeric types. |
302 |
Scale is no longer ignored. |
303 |
|
304 |
2. Fix issues with setting SQL Param values using SetAsString with Date values |
305 |
not in locale format but which are recognised by Firebird. Date values that |
306 |
cannot be converted to a string using Pascal library are now passed through |
307 |
to Firebird as Text Strings. |
308 |
|
309 |
3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns |
310 |
UTF8 and not UNICODE_FSS. |
311 |
|
312 |
4. Charset ID problem. When using Firebird 3, with no default database character set |
313 |
and a column has a non-default collation specified, an incorrect character set |
314 |
id was being reported that could result in a 'division by zero' error when |
315 |
used by IBX. This has now been fixed. |
316 |
|
317 |
5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID, |
318 |
CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as |
319 |
the character sets supported can be updated on a per database basis. That is |
320 |
it is possible to add a (Firebird) user defined character set to a database. |
321 |
|
322 |
6. Add RegisterCharSet to IAttachment. This is used to register a user defined character |
323 |
set supported by Firebird with the API. |
324 |
|
325 |
7. Add missing isc_info_db_read_only to list of decoded Database Information items |
326 |
in FBOutputBlock.pas and update test suite to include this item. |
327 |
|
328 |
8. FB30Client: avoid always using "StartMultiple" when only a single database attachment. |
329 |
|
330 |
9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client |
331 |
library or finding it by disk location, the PATH environment variable is now also set to |
332 |
include the FIREBIRD directory. This is to ensure that the correct dlls in the |
333 |
firebird client library dependencies are loaded. |
334 |
|
335 |
10. Testsuite: Ensure consistent UTF-8 output on Windows console. |
336 |
|
337 |
11. Testsuite: Update Windows script to include FPC 3.0.4 in search path. |
338 |
|
339 |
12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer |
340 |
|
341 |
13. FB30Statement: A check has been added to ensure that all SQL Parameters |
342 |
have been given a value (including NULL). Previously, failing to set the |
343 |
value of an SQL Parameter could give rise to unpredictable results or |
344 |
an SQLDA error. |
345 |
|
346 |
14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set. |
347 |
|
348 |
15. FBAttachment: Avoid string reference count error when processing an Ansistring |
349 |
parameter in an array of const passed to IAttachment.OpenCursor, etc. |
350 |
|
351 |
16. FBAttachment: Allow for WideString and UnicodeString parameters in an array |
352 |
of const passed to IAttachment.OpenCursor, etc. |
353 |
|
354 |
|
355 |
FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000 |
356 |
|
357 |
1. Change syntax to Mode Delphi |
358 |
|
359 |
2. Change all uses of string type to explicit AnsiString in order to ensure |
360 |
compatibility between Delphi and FPC. |
361 |
|
362 |
3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs |
363 |
defined for each interface. |
364 |
|
365 |
4. Generics syntax variations for Delphi added |
366 |
|
367 |
5. PChar replaced with PByte expect where an actual string is being referenced, |
368 |
where PAnsiChar is used instead. |
369 |
|
370 |
6. Review of type definitions in IBExternals to ensure Delphi compatibility |
371 |
|
372 |
7. Testsuite updated for Delphi |
373 |
|
374 |
FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000 |
375 |
|
376 |
1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with |
377 |
large blobs and the FB3 API. |
378 |

|
382 |
3. Avoid invalid XSQLDA error when the only parameter is updated to null |
383 |
|
384 |
4. Array Handling: fix problem with text arrays with character set none. When the |
385 |
DB connection has a default character set (e.g. UTF8), an error is raised by |
386 |
Firebird if the space allocated is not enough to allow for transliteration, even |
387 |
though it is not required for character set none. |

an array dimension is not mistaken for a named parameter prefix. |
398 |
|
399 |
9. Trim function no longer applied to result of GetAsString for SQL_TEXT |
400 |
when Character set is octets. Avoids loss of non printable characters at start of string. |
401 |
|
402 |
10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance |
403 |
statistics for the last action. Requires use of procedure IStatement.EnableStatistics |
404 |
to enable stats gathering. |
