1 FBINTF Change Log version (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
2
3 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
4 case sensitive
5
6 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
7
8 3. New API Calls:
9 IColumnMetaData.GetStatement
10 IColumnMetaData.GetTransaction
11 ISQLData.GetStrLength
12 IResults.GetStatement
13 IAttachment.OpenBlob (using Blob metadata)
14 IAttachment.OpenArray (using array metadata)
15
16 4. FBMessages: removal of unused messages
17
18 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19
20 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21
22 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
23
24 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
25 where the second character of the parameter name is a numeric.
26
27 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
28 This returns the isc_version connection information as one or more lines.
29 This is the same information as returned by isql with the -z option.
30
31 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
32 is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
33 compiler option then the Firebird 3 API is no longer compiled in.
34
35 4. IColumnMetaData: new method.
36
37 TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38 dfDateTime, {SQL DATETIME}
39 dfTime);
40
41 function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42
43 This returns the max. number of characters returned by the "AsString" method
44 when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
45
46 5. Additional argument for IAttachment.PrepareWithNamedParameters -
47 CaseSensitiveParams: boolean = false
48
49 If this argument is set to true then SQL parameter names are assumed to be case
50 sensitive and must be referenced (using ISQLParams.ByName) using the case
51 sensitive name.
52
53 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
54 is of type VarChar or Char to set the parameter to a numeric value (e.g. using
55 .AsCurrency) and then subsequently to update the value to a non-numeric string
56 using .AsString.

60 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61
62 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63
64 2. Restrict IsMultiThread check to Unix only for compatibility with
65 https://bugs.freepascal.org/view.php?id=30535
66
67 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
68 named parameters and is intended to avoid problems with (e.g.) Execute Block
69 and processing internal parameters as statement parameters.
70
71 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72 or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
73
74 5. New function added to IB.pas
75
76 function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77
78 This allows a Firebird Library to be loaded from an explicit path. use the
79 IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
80 the library. It is possible to load Firebird libraries from different locations
81 simultaneously, each with a distinct IFirebirdAPI.
82
83 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84
85 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86 program compiled with -CR command line switch.
87
88 2. IServiceManager additions (informational):
89 function getProtocol: TProtocol;
90 function getPortNo: AnsiString;
91
92 3. IServiceManager improved error handling. Interfaces changed:
93 function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
94 function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
95 function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
96
97 4. IAttachment addition (informational)
98 function GetSecurityDatabase: AnsiString;
99
100 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
101 thus now returns accumulated stats for a select statement from opening a cursor
102 up to the last fetch.
103
104 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105 the problem.
106
107 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108 replaces deprecated "comp" type.
109
110 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111
112 11. URL Connection Strings: inet4 and inet6 now recognised.
113
114 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115
116 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117
118
119 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120
121 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122
123 2. IAttachment: add two new methods
124 function HasDefaultCharSet: boolean;
125 function GetDefaultCharSetID: integer;
126
127 These return, respectively, true if a connection default character set was
128 specified and the character set id of the connection default character set.
129 The DefaultCharSetID is cached when the connection is opened and hence does not
130 require a database lookup.
131
132 3. Avoid exception when a text blob is a stored procedure parameter.
133
134 4. Update test suite to include a test for a stored proc returning a text blob.
135
136 5. IAttachment: add
137 function GetRemoteProtocol: AnsiString;
138 function GetODSMajorVersion: integer;
139 function GetODSMinorVersion: integer;
140 function GetAuthenticationMethod: AnsiString;
141
142 These results are cached when the connection is opened and hence do not
143 require a database lookup.
144
145 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146 connect string used to create/connect to the database.
147
148 7. IAttachment: Create Database using SQL statement. The username and password
149 are now extracted and used to populate a DPB made available via IAttachment.getDPB.
150 It is now possible to use IAttachment disconnect/connect to reconnect to
151 a database for which the initial connection was established by a create
152 database sql statement. Available in FPC only.
153
154 8. Update Test 1 to test 5, 6 and 7 above.
155
156 9. IBUtils code tidy up.
157
158 10. Parameter Block interfaces "find" method. As documented, this should have
159 returned a nil interface when the item could not be found. Instead, an empty
160 interface item was returned. "Find" now works as documented and will return
161 a nil interface if the item cannot be found.
162
163 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164
165 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
166 requests with additional parameters. This is to enable support for fb_info_page_contents
167 (return of page contents). Response to fb_info_page_contents returned as
168 a string with code page CP_NONE.
169
170 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171 test suite updated.
172
173 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
174 a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
175
176 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
177 An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
178 default connection port to be specified.
179
180 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181
182 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183 Scale is no longer ignored.
184
185 2. Fix issues with setting SQL Param values using SetAsString with Date values
186 not in locale format but which are recognised by Firebird. Date values that
187 cannot be converted to a string using Pascal library are now passed through
188 to Firebird as Text Strings.
189
190 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191 UTF8 and not UNICODE_FSS.
192
193 4. Charset ID problem. When using Firebird 3, with no default database character set
194 and a column has a non-default collation specified, an incorrect character set
195 id was being reported that could result in a 'division by zero' error when
196 used by IBX. This has now been fixed.
197
198 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
199 CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
200 the character sets supported can be updated on a per database basis. That is
201 it is possible to add a (Firebird) user defined character set to a database.
202
203 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204 set supported by Firebird with the API.
205
206 7. Add missing isc_info_db_read_only to list of decoded Database Information items
207 in FBOutputBlock.pas and update test suite to include this item.
208
209 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210
211 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
212 library or finding it by disk location, the PATH environment variable is now also set to
213 include the FIREBIRD directory. This is to ensure that the correct dlls in the
214 firebird client library dependencies are loaded.
215
216 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217
218 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219
220 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221
222 13. FB30Statement: A check has been added to ensure that all SQL Parameters
223 have been given a value (including NULL). Previously, failing to set the
224 value of an SQL Parameter could give rise to unpredictable results or
225 an SQLDA error.
226
227 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228
229 15. FBAttachment: Avoid string reference count error when processing an Ansistring
230 parameter in an array of const passed to IAttachment.OpenCursor, etc.
231
232 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233 of const passed to IAttachment.OpenCursor, etc.
234
235
236 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
237
238 1. Change syntax to Mode Delphi
239
240 2. Change all uses of string type to explicit AnsiString in order to ensure
241 compatibility between Delphi and FPC.
242
243 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244 defined for each interface.
245
246 4. Generics syntax variations for Delphi added
247
248 5. PChar replaced with PByte expect where an actual string is being referenced,
249 where PAnsiChar is used instead.
250
251 6. Review of type definitions in IBExternals to ensure Delphi compatibility
252
253 7. Testsuite updated for Delphi
254
255 FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
256
257 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258 large blobs and the FB3 API.
259
260 2. Update Event Handling algorithm to avoid looping due to recreation of the
261 event block.
262
263 3. Avoid invalid XSQLDA error when the only parameter is updated to null
264
265 4. Array Handling: fix problem with text arrays with character set none. When the
266 DB connection has a default character set (e.g. UTF8), an error is raised by
267 Firebird if the space allocated is not enough to allow for transliteration, even
268 though it is not required for character set none.
269
270 5. IBUtils: List of reserved words brought up-to-date
271
272 6. Add ISQL style performance statistics collection to IStatement
273
274 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
275 CREATE DATABASE statement.
276
277 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
278 an array dimension is not mistaken for a named parameter prefix.
279
280 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
281 when Character set is octets. Avoids loss of non printable characters at start of string.
282
283 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
284 statistics for the last action. Requires use of procedure IStatement.EnableStatistics
285 to enable stats gathering.
286
287 11. API Version information added as constants to IB.pas
288
289 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
290
291 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
292
