1 FBINTF Change Log version (1.1-5 Build 11664) Thu, 11 Apr 2019 09:43:40 +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 FBINTF Change Log version (1.1-4 Build 11515) Fri, 28 Dec 2018 10:04:19 +0000
9
10 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
11 where the second character of the parameter name is a numeric.
12
13 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
14 This returns the isc_version connection information as one or more lines.
15 This is the same information as returned by isql with the -z option.
16
17 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
18 is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
19 compiler option then the Firebird 3 API is no longer compiled in.
20
21 4. IColumnMetaData: new method.
22
23 TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
24 dfDateTime, {SQL DATETIME}
25 dfTime);
26
27 function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
28
29 This returns the max. number of characters returned by the "AsString" method
30 when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
31
32 5. Additional argument for IAttachment.PrepareWithNamedParameters -
33 CaseSensitiveParams: boolean = false
34
35 If this argument is set to true then SQL parameter names are assumed to be case
36 sensitive and must be referenced (using ISQLParams.ByName) using the case
37 sensitive name.
38
39 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
40 is of type VarChar or Char to set the parameter to a numeric value (e.g. using
41 .AsCurrency) and then subsequently to update the value to a non-numeric string
42 using .AsString.

46 FBINTF Change Log version (1.1-3) Wed, 05 Dec 2018 14:28:10 +0000
47
48 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
49
50 2. Restrict IsMultiThread check to Unix only for compatibility with
51 https://bugs.freepascal.org/view.php?id=30535
52
53 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
54 named parameters and is intended to avoid problems with (e.g.) Execute Block
55 and processing internal parameters as statement parameters.
56
57 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
58 or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
59
60 5. New function added to IB.pas
61
62 function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
63
64 This allows a Firebird Library to be loaded from an explicit path. use the
65 IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
66 the library. It is possible to load Firebird libraries from different locations
67 simultaneously, each with a distinct IFirebirdAPI.
68
69 FBINTF Change Log version (1.1-2) Mon, 16 Apr 2018 09:30:32 +0100
70
71 1. Firebird.pas: {$OBJECTCHECKS OFF} added to file to avoid runtime error when
72 program compiled with -CR command line switch.
73
74 2. IServiceManager additions (informational):
75 function getProtocol: TProtocol;
76 function getPortNo: AnsiString;
77
78 3. IServiceManager improved error handling. Interfaces changed:
79 function Start(Request: ISRB; RaiseExceptionOnError: boolean=true): boolean;
80 function Query(SQPB: ISQPB; Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
81 function Query(Request: ISRB; RaiseExceptionOnError: boolean=true) :IServiceQueryResults; overload;
82
83 4. IAttachment addition (informational)
84 function GetSecurityDatabase: AnsiString;
85
86 5. IStatement: performance counters now updated after each Fetch. GetPerfStatistics
87 thus now returns accumulated stats for a select statement from opening a cursor
88 up to the last fetch.
89
90 6. DARWIN: uloadlibrary.inc bug fix. Many thanks to Luigi Naimi for correcting
91 the problem.
92
93 7. Type change: "TPerfCounters = array[TPerfStats] of Int64". Note "Int64"
94 replaces deprecated "comp" type.
95
96 10. Testsuite Test10 updated to include thread synchronisation for event reporting.
97
98 11. URL Connection Strings: inet4 and inet6 now recognised.
99
100 12. IBUtils: Parse and Make Connect String now recognise URL style loopback syntax.
101
102 13. IAttachment.CharSetName2CharSetID is now performed case insensitive.
103
104
105 FBINTF Change Log version (1.1-1) Tue, 27 Feb 2018 16:51:16 +0000
106
107 1. IBUtils.QuoteIdentifierIfNeeded: Add check for space character.
108
109 2. IAttachment: add two new methods
110 function HasDefaultCharSet: boolean;
111 function GetDefaultCharSetID: integer;
112
113 These return, respectively, true if a connection default character set was
114 specified and the character set id of the connection default character set.
115 The DefaultCharSetID is cached when the connection is opened and hence does not
116 require a database lookup.
117
118 3. Avoid exception when a text blob is a stored procedure parameter.
119
120 4. Update test suite to include a test for a stored proc returning a text blob.
121
122 5. IAttachment: add
123 function GetRemoteProtocol: AnsiString;
124 function GetODSMajorVersion: integer;
125 function GetODSMinorVersion: integer;
126 function GetAuthenticationMethod: AnsiString;
127
128 These results are cached when the connection is opened and hence do not
129 require a database lookup.
130
131 6. IAttachment: add "function GetConnectString: AnsiString;" This returns the
132 connect string used to create/connect to the database.
133
134 7. IAttachment: Create Database using SQL statement. The username and password
135 are now extracted and used to populate a DPB made available via IAttachment.getDPB.
136 It is now possible to use IAttachment disconnect/connect to reconnect to
137 a database for which the initial connection was established by a create
138 database sql statement. Available in FPC only.
139
140 8. Update Test 1 to test 5, 6 and 7 above.
141
142 9. IBUtils code tidy up.
143
144 10. Parameter Block interfaces "find" method. As documented, this should have
145 returned a nil interface when the item could not be found. Instead, an empty
146 interface item was returned. "Find" now works as documented and will return
147 a nil interface if the item cannot be found.
148
149 11. DBInformation: support added for isc_info_active_tran_count and isc_info_creation_date.
150
151 12. DBInformation: New interfaces: IDIRB and IDIRBItem added to support DB Information
152 requests with additional parameters. This is to enable support for fb_info_page_contents
153 (return of page contents). Response to fb_info_page_contents returned as
154 a string with code page CP_NONE.
155
156 13. DBInformation: Support for fb_info_pages_used and fb_info_pages_free added, plus
157 test suite updated.
158
159 14. DBInformation: Support for fb_info_crypt_key (Firebird 3.0.3 onwards) added as
160 a string type, and fb_info_conn_flags (Firebird 3.0.3 onwards) added as an integer type.
161
162 15. Service Manager: List of protocols supported expanded to include inet, wnet and xnet.
163 An overloaded version of IIFirebirdAPI.GetServiceManager also allows a non
164 default connection port to be specified.
165
166 FBINTF Change Log version (1.1-0) Sun, 07 Jan 2018 15:20:02 +0000
167
168 1. Fix issues with setting SQL Param values using SetAsString with Numeric types.
169 Scale is no longer ignored.
170
171 2. Fix issues with setting SQL Param values using SetAsString with Date values
172 not in locale format but which are recognised by Firebird. Date values that
173 cannot be converted to a string using Pascal library are now passed through
174 to Firebird as Text Strings.
175
176 3. Lookup character set name by codepage amended to ensure that CP_UTF8 returns
177 UTF8 and not UNICODE_FSS.
178
179 4. Charset ID problem. When using Firebird 3, with no default database character set
180 and a column has a non-default collation specified, an incorrect character set
181 id was being reported that could result in a 'division by zero' error when
182 used by IBX. This has now been fixed.
183
184 5. Move GetCharsetName, CharSetID2CodePage, CodePage2CharSetID, CharSetName2CharSetID,
185 CharSetWidth from IFirebirdAPI to IAttachment. This is a better data model as
186 the character sets supported can be updated on a per database basis. That is
187 it is possible to add a (Firebird) user defined character set to a database.
188
189 6. Add RegisterCharSet to IAttachment. This is used to register a user defined character
190 set supported by Firebird with the API.
191
192 7. Add missing isc_info_db_read_only to list of decoded Database Information items
193 in FBOutputBlock.pas and update test suite to include this item.
194
195 8. FB30Client: avoid always using "StartMultiple" when only a single database attachment.
196
197 9. Loading Windows fbclient.dll: when using the FIREBIRD variable to locate the client
198 library or finding it by disk location, the PATH environment variable is now also set to
199 include the FIREBIRD directory. This is to ensure that the correct dlls in the
200 firebird client library dependencies are loaded.
201
202 10. Testsuite: Ensure consistent UTF-8 output on Windows console.
203
204 11. Testsuite: Update Windows script to include FPC 3.0.4 in search path.
205
206 12. FB30Statement: Protect call to "Move" and avoid calling with a nil pointer
207
208 13. FB30Statement: A check has been added to ensure that all SQL Parameters
209 have been given a value (including NULL). Previously, failing to set the
210 value of an SQL Parameter could give rise to unpredictable results or
211 an SQLDA error.
212
213 14. FB30Statement/FB25Statement: Set SQLParam "modified" when string value set.
214
215 15. FBAttachment: Avoid string reference count error when processing an Ansistring
216 parameter in an array of const passed to IAttachment.OpenCursor, etc.
217
218 16. FBAttachment: Allow for WideString and UnicodeString parameters in an array
219 of const passed to IAttachment.OpenCursor, etc.
220
221
222 FBINTF Change Log version (1.0-2) Sat, 04 Mar 2017 14:43:56 +0000
223
224 1. Change syntax to Mode Delphi
225
226 2. Change all uses of string type to explicit AnsiString in order to ensure
227 compatibility between Delphi and FPC.
228
229 3. Various syntax changes to ensure Delphi and FPC compilation including GUIDs
230 defined for each interface.
231
232 4. Generics syntax variations for Delphi added
233
234 5. PChar replaced with PByte expect where an actual string is being referenced,
235 where PAnsiChar is used instead.
236
237 6. Review of type definitions in IBExternals to ensure Delphi compatibility
238
239 7. Testsuite updated for Delphi
240
241 FBINTF Change Log version (1.0-1) Fri, 24 Feb 2017 12:17:57 +0000
242
243 1. Limit maximum Blob segment read/write to MaxuShort. Avoids data loss with
244 large blobs and the FB3 API.
245
246 2. Update Event Handling algorithm to avoid looping due to recreation of the
247 event block.
248
249 3. Avoid invalid XSQLDA error when the only parameter is updated to null
250
251 4. Array Handling: fix problem with text arrays with character set none. When the
252 DB connection has a default character set (e.g. UTF8), an error is raised by
253 Firebird if the space allocated is not enough to allow for transliteration, even
254 though it is not required for character set none.
255
256 5. IBUtils: List of reserved words brought up-to-date
257
258 6. Add ISQL style performance statistics collection to IStatement
259
260 7. Add IFirebirdAPI.CreateDatabase variant to allow execution of user provided
261 CREATE DATABASE statement.
262
263 8. Update SQL Statement parsing to allow for Array Dimensions. That is so that the ':' in
264 an array dimension is not mistaken for a named parameter prefix.
265
266 9. Trim function no longer applied to result of GetAsString for SQL_TEXT
267 when Character set is octets. Avoids loss of non printable characters at start of string.
268
269 10. Add function GetPerfStatistics to IStatement. This returns ISQL like performance
270 statistics for the last action. Requires use of procedure IStatement.EnableStatistics
271 to enable stats gathering.
272
273 11. API Version information added as constants to IB.pas
274
275 12. BlobMetaData character set id should now be the same as that given by IColumnMetaData.GetCharSetID
276
277 13. Firebird Character set "NONE" now interpreted as codepage CP_ACP.
278
