1 > FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
2 >
3 > 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
4 >
5 > 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
6 >   using remote protocol. Scrollable cursors with remote database expected to
7 >   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
8 >   a not supported error.
9 >
10 > 3. IStatement: new function;
11 >    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
12 >    TStatementFlags = set of TStatementFlag;
13 >    function GetFlags: TStatementFlags;
14 >
15 > 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
16 >   compatibility.
17 >   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
18 >   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
19 >   to be used with Update...Retruning statements that return a singleton row,
20 >   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
21 >   it will open the cursor and return the first row only.
22 >
23 > 5. ITransaction: new functions:
24 >    function GetIsReadOnly: boolean;
25 >    function GetTransactionID: integer;
26 >    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
27 >    function GetTrInformation(Request: byte): ITrInformation; overload;
28 >
29 >   The latter two return the Transaction Information block. The first two extract
30 >   information the Transaction Information block
31 >
32 > 6. New function TSQLTokeniser.ReadCharacters
33 >   Used internally.
34 >
35 > 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
36 >   parameter placeholders instead of named parameters.
37 >
38 > 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
39 >   transaction handle is now ignored if Rollback/Commit is called with Force=true
40 >
41 > FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
42 >
43 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
44 >
45 > 2. IStatement: new methods:
46 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
47 >    function GetStaleReferenceChecks: boolean;
48 >
49 >   In previous versions, stale reference checks were always enabled. This allows the
50 >   user to disable them on a per statement basis. Note this can risk out-of-date
51 >   statement BLR. See User Guide.
52 >
53 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
54 >   stored procedure and hence avoids replacing named parameters within a containing
55 >   BEGIN..END block.
56 >
57 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
58 >   zero is now treated as a special case to avoid the risk of floating point
59 >   rounding errors affecting pure integers.
60 >
61 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
62 >
63 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
64 >   SQL Parameter metadata (methods moved from ISQLParam).
65 >
66 > 7. ISQLParam: new method
67 >     function getColMetadata: IParamMetaData;
68 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
69 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
70 >   setting a VARCHAR column to an integer value.
71 >
72 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
73 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
74 >   also IAttachment:
75 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
76 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
77 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
78 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
79 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
80 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
81 >                       GenerateParamNames: boolean=false;
82 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
83 >
84 > 9. Support for scrollable cursors added. New/updated methods:
85 >   IAttachment:
86 >    function HasScollableCursors: boolean;
87 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
88 >                             Scrollable: boolean=false): IResultSet; overload;
89 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
90 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
91 >                             params: array of const): IResultSet; overload;
92 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
93 >                             params: array of const): IResultSet; overload;
94 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
95 >                             params: array of const): IResultSet; overload;
96 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
97 >                             Scrollable: boolean=false): IResultSet; overload;
98 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
99 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
100 >                             params: array of const): IResultSet; overload;
101 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
102 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
103 >                             params: array of const): IResultSet; overload;
104 >   IStatement:
105 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
106 >   IResultSet:
107 >    function FetchPrior: boolean; {fetch previous record}
108 >    function FetchFirst:boolean; {fetch first record}
109 >    function FetchLast: boolean; {fetch last record}
110 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
111 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
112 >    function IsBof: boolean;
113 >
114 > 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
115 >
116 > 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
117 >    may be noticeable when a line separator occurs inside quoted text. The quoted text
118 >    output by the tokeniser will now use the platform specific lineEnding regardless
119 >    of whether the input uses the CRLF or LF as a line separator.
120 >
121 > 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
122 >
123 >
124 > FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
125 >
126 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
127 >
128 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
129 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
130 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
131 >   separate server interaction. This is intended as a performance optimisation.
132 >
133 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
134 >   IAttachment interface functions:
135 >
136 >    function GetInlineBlobLimit: integer;
137 >    procedure SetInlineBlobLimit(limit: integer);
138 >
139 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
140 >   user as the functionality is embedded in the implementation of the IStatement
141 >   interface. Three new functions are defined:
142 >
143 >    procedure AddToBatch;
144 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
145 >    procedure CancelBatch;
146 >    function GetBatchCompletion: IBatchCompletion;
147 >    function GetBatchRowLimit: integer;
148 >    procedure SetBatchRowLimit(aLimit: integer);
149 >
150 >   Also
151 >
152 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
153 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
154 >
155 >   For more information see the User Guide.
156 >
157 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
158 >   provided with the EIBInterBaseError now include all three parts.
159 >
160 > 5. Firebird.pas and include files updated to Firebird 4.0.0
161 >
162 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
163 >   Returns SQL Statement type as a text string;
164 >
165 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
166 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
167 >
168 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
169 >
170 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
171 >   typo in FB30Statement.pas that caused an unknown parameter error.
172 >
173 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
174 >
175 > 1. Imported (Firebird) constants updated for Firebird 4.
176 >
177 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
178 >
179 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
180 >
181 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
182 >
183 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
184 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
185 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
186 >   type safe access to the Firebird IMaster interface and avoids the need to turn
187 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
188 >
189 > 6. New IFirebirdAPI Calls:
190 >    function HasLocalTZDB: boolean;
191 >    function HasTimeZoneSupport: boolean;
192 >    function HasExtendedTZSupport: boolean;
193 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
194 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
195 >
196 > 7. New IAttachment Calls:
197 >    function HasDecFloatSupport: boolean;
198 >    function GetTimeZoneServices: ITimeZoneServices;
199 >    function HasTimeZoneSupport: boolean;
200 >
201 > 8. New Interface ITimeZoneServices.
202 >
203 > 9. New ISQLData API Calls:
204 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
205 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
206 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
207 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
208 >    function GetAsUTCDateTime: TDateTime;
209 >    function GetAsBCD: tBCD;
210 >
211 > 10. New ISQLParam API Calls
212 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
213 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
214 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

220 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
221 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
222 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
223 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
224 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
225 >    procedure SetAsBcd(aValue: tBCD);
226 >
227 > 11. New IArray API Calls
228 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
229 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
230 >    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

236 >    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
237 >
238 > 12. Utility functions in IBUtils
239 >    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
240 >              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
241 >    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
242 >    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;

245 >    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
246 >
247 > 13. IDPB, ITPB and ISPB: new interface method
248 >      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
249 >    This is used to add a parameter block item by the string equivalent of its
250 >    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'

252 > 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
253 >      function getParamTypeName: AnsiString;
254 >
255 > 15. fb_shutdown now called before unloading Firebird library. This can avoid a
256 >     SIGEVENT error when a programme using the embeded server is unloaded.
257 >
258 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
259 >
260 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
261 >   with a Firebrid 3 client library.
262 >
263 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
264 >    If a client library path is not explicitly provided and the FIREBIRD environment
265 >    variable is set then the directory given by this variable and any 'lib' subdirectory
266 >    are searched for the Firebird client library. Only if none is found, is the default
267 >    client library used.
268 >
269 > 3.  IUtil.FormatStatus now used to format error messages when using new API
270 >
271 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
272 >
273 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
274 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
275 >    that the byte length corresponds to the number of characters specified for the column.
276 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
277 >    correct behaviour but may affect some implementations that relied upon automatic
278 >    trimming of trailing white space.
279 >
280 > 6.  New IFirebirdAPI Calls:
281 >      function GetClientMajor: integer;
282 >      function GetClientMinor: integer;
283 >
284 > 7.  IColumnMetaData and IArrayMetaData: new method
285 >      function GetCharSetWidth: integer;
286 >
287 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
288 >
289 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
290 >   case sensitive
291 >
292 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
293 >
294 > 3. New API Calls:
295 >        IColumnMetaData.GetStatement
296 >        IColumnMetaData.GetTransaction
297 >        ISQLData.GetStrDataLength
298 >        IResults.GetStatement
299 >        IAttachment.OpenBlob (using Blob metadata)
300 >        IAttachment.OpenArray (using array metadata)
301 >
302 > 4. FBMessages: removal of unused messages
303 >
304 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
305 >
306 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
307 >
308 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
309 >
310 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
311 >   where the second character of the parameter name is a numeric.
312 >
313 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
314 >   This returns the isc_version connection information as one or more lines.
315 >   This is the same information as returned by isql with the -z option.
316 >
317 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
318 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
319 >   compiler option then the Firebird 3 API is no longer compiled in.
320 >
321 > 4. IColumnMetaData: new method.
322 >
323 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
324 >                        dfDateTime,   {SQL DATETIME}
325 >                        dfTime);
326 >
327 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
328 >
329 >   This returns the max. number of characters returned by the "AsString" method
330 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
331 >
332 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
333 >     CaseSensitiveParams: boolean = false
334 >
335 >   If this argument is set to true then SQL parameter names are assumed to be case
336 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
337 >   sensitive name.
338 >
339 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
340 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
341 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
342 >   using .AsString.

347 >
348 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
349 >
350 > 2. Restrict IsMultiThread check to Unix only for compatibility with
351 >   https://bugs.freepascal.org/view.php?id=30535
352 >
353 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
354 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
355 >   and processing internal parameters as statement parameters.
356 >
357 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
358 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
359 >
360 > 5. New function added to IB.pas
361 >
362 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
363 >
364 >   This allows a Firebird Library to be loaded from an explicit path. use the
365 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
366 >   the library. It is possible to load Firebird libraries from different locations
367 >   simultaneously, each with a distinct IFirebirdAPI.
