1 tony 305 FBINTF Change Log version (1.1-5 Build 12044) Fri, 17 Apr 2020 12:30:01 +0100
2 tony 287
3 tony 305 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
4     case sensitive
5 tony 287
6 tony 305 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
7 tony 287
8 tony 305 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 tony 291
16 tony 305 4. FBMessages: removal of unused messages
17 tony 291
18 tony 305 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
19 tony 291
20 tony 305 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
21 tony 291
22 tony 305 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
23 tony 291
24 tony 305 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 tony 266
27 tony 305 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 tony 272
31 tony 305 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 tony 266
35 tony 305 4. IColumnMetaData: new method.
36 tony 266
37 tony 305 TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
38     dfDateTime, {SQL DATETIME}
39     dfTime);
40 tony 263
41 tony 305 function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
42 tony 267
43 tony 305 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 tony 270
46 tony 305 5. Additional argument for IAttachment.PrepareWithNamedParameters -
47     CaseSensitiveParams: boolean = false
48 tony 270
49 tony 305 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 tony 270
53 tony 305 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 tony 305 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
61 tony 270
62 tony 305 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
63 tony 270
64 tony 305 2. Restrict IsMultiThread check to Unix only for compatibility with
65     https://bugs.freepascal.org/view.php?id=30535
66 tony 270
67 tony 305 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 tony 270
71 tony 305 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
72     or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
73 tony 270
74 tony 305 5. New function added to IB.pas
75 tony 270
76 tony 305 function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
77 tony 270
78 tony 305 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 tony 270
83 tony 305 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
84 tony 271
85 tony 305 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
86     program compiled with -CR command line switch.
87 tony 272
88 tony 305 2. IServiceManager additions (informational):
89     function getProtocol: TProtocol;
90     function getPortNo: AnsiString;
91 tony 272
92 tony 305 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 tony 272
97 tony 305 4. IAttachment addition (informational)
98     function GetSecurityDatabase: AnsiString;
99 tony 272
100 tony 305 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 tony 272
104 tony 305 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
105     the problem.
106 tony 272
107 tony 305 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
108     replaces deprecated "comp" type.
109 tony 272
110 tony 305 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
111 tony 272
112 tony 305 11. URL Connection Strings: inet4 and inet6 now recognised.
113 tony 272
114 tony 305 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
115 tony 272
116 tony 305 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
117 tony 272
118 tony 267
119 tony 305 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
120 tony 263
121 tony 305 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
122 tony 263
123 tony 305 2. IAttachment: add two new methods
124     function HasDefaultCharSet: boolean;
125     function GetDefaultCharSetID: integer;
126 tony 263
127 tony 305 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 tony 263
132 tony 305 3. Avoid exception when a text blob is a stored procedure parameter.
133 tony 263
134 tony 305 4. Update test suite to include a test for a stored proc returning a text blob.
135 tony 263
136 tony 305 5. IAttachment: add
137     function GetRemoteProtocol: AnsiString;
138     function GetODSMajorVersion: integer;
139     function GetODSMinorVersion: integer;
140     function GetAuthenticationMethod: AnsiString;
141 tony 263
142 tony 305 These results are cached when the connection is opened and hence do not
143     require a database lookup.
144 tony 263
145 tony 305 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
146     connect string used to create/connect to the database.
147 tony 263
148 tony 305 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 tony 263
154 tony 305 8. Update Test 1 to test 5, 6 and 7 above.
155 tony 263
156 tony 305 9. IBUtils code tidy up.
157 tony 263
158 tony 305 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 tony 241
163 tony 305 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
164 tony 241
165 tony 305 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 tony 101
170 tony 305 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
171     test suite updated.
172 tony 209
173 tony 305 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 tony 209
176 tony 305 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 tony 209
180 tony 305 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
181 tony 209
182 tony 305 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
183     Scale is no longer ignored.
184 tony 209
185 tony 305 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 tony 209
190 tony 305 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
191     UTF8 and not UNICODE_FSS.
192 tony 209
193 tony 305 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 tony 209
198 tony 305 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 tony 209
203 tony 305 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
204     set supported by Firebird with the API.
205 tony 209
206 tony 305 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 tony 209
209 tony 305 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
210 tony 209
211 tony 305 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 tony 209
216 tony 305 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
217 tony 209
218 tony 305 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
219 tony 209
220 tony 305 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
221 tony 209
222 tony 305 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 tony 209
227 tony 305 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
228 tony 209
229 tony 305 15. FBAttachment: Avoid string reference count error when processing an Ansistring
230     parameter in an array of const passed to IAttachment.OpenCursor, etc.
231 tony 209
232 tony 305 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
233     of const passed to IAttachment.OpenCursor, etc.
234 tony 209
235    
236 tony 305 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
237 tony 209
238 tony 305 1. Change syntax to Mode Delphi
239 tony 209
240 tony 305 2. Change all uses of string type to explicit AnsiString in order to ensure
241     compatibility between Delphi and FPC.
242 tony 209
243 tony 305 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
244     defined for each interface.
245 tony 221
246 tony 305 4. Generics syntax variations for Delphi added
247 tony 221
248 tony 305 5. PChar replaced with PByte expect where an actual string is being referenced,
249     where PAnsiChar is used instead.
250 tony 221
251 tony 305 6. Review of type definitions in IBExternals to ensure Delphi compatibility
252 tony 225
253 tony 305 7. Testsuite updated for Delphi
254 tony 225
255 tony 305 FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
256 tony 225
257 tony 305 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
258     large blobs and the FB3 API.
259 tony 225
260 tony 305 2. Update Event Handling algorithm to avoid looping due to recreation of the
261     event block.
262 tony 226
263 tony 305 3. Avoid invalid XSQLDA error when the only parameter is updated to null
264 tony 227
265 tony 305 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 tony 229
270 tony 305 5. IBUtils: List of reserved words brought up-to-date
271 tony 229
272 tony 305 6. Add ISQL style performance statistics collection to IStatement
273 tony 229
274 tony 305 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
275     CREATE DATABASE statement.
276 tony 229
277 tony 305 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 tony 229
280 tony 305 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 tony 229
283 tony 305 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 tony 231
287 tony 305 11. API Version information added as constants to IB.pas
288 tony 209
289 tony 305 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
290 tony 151
291 tony 305 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
292 tony 151
293 tony 305 FBINTF Change Log version (1.0-0) Tue, 06 Dec 2016 10:33:47 +0000
294 tony 101
295 tony 305 1. Initial Release
296 tony 101
