2 >
3 > 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
4 >
5 > 2. IStatement: new methods:
6 >    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
7 >    function GetStaleReferenceChecks: boolean;
8 >
9 >   In previous versions, stale reference checks were always enabled. This allows the
10 >   user to disable them on a per statement basis. Note this can risk out-of-date
11 >   statement BLR. See User Guide.
12 >
13 > 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
14 >   stored procedure and hence avoids replacing named parameters within a containing
15 >   BEGIN..END block.
16 >
17 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
18 >   zero is now treated as a special case to avoid the risk of floating point
19 >   rounding errors affecting pure integers.
20 >
21 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
22 >
23 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
24 >   SQL Parameter metadata (methods moved from ISQLParam).
25 >
26 > 7. ISQLParam: new method
27 >     function getColMetadata: IParamMetaData;
28 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
29 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
30 >   setting a VARCHAR column to an integer value.
31 >
32 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
33 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
34 >   also IAttachment:
35 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
36 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
37 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
38 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
39 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
40 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
41 >                       GenerateParamNames: boolean=false;
42 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
43 >
44 > 9. Support for scrollable cursors added. New/updated methods:
45 >   IFirebirdAPI:
46 >     function HasScollableCursors: boolean;
47 >   IAttachment:
48 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
49 >                             Scrollable: boolean=false): IResultSet; overload;
50 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
51 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
52 >                             params: array of const): IResultSet; overload;
53 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
54 >                             params: array of const): IResultSet; overload;
55 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
56 >                             params: array of const): IResultSet; overload;
57 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
58 >                             Scrollable: boolean=false): IResultSet; overload;
59 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
60 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
61 >                             params: array of const): IResultSet; overload;
62 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
63 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
64 >                             params: array of const): IResultSet; overload;
65 >   IStatement:
66 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
67 >   IResultSet:
68 >    function FetchPrior: boolean; {fetch previous record}
69 >    function FetchFirst:boolean; {fetch first record}
70 >    function FetchLast: boolean; {fetch last record}
71 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
72 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
73 >    function IsBof: boolean;

78 >
79 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
80 >
81 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
82 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
83 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
84 >   separate server interaction. This is intended as a performance optimisation.
85 >
86 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
87 >   IAttachment interface functions:
88 >
89 >    function GetInlineBlobLimit: integer;
90 >    procedure SetInlineBlobLimit(limit: integer);
91 >
92 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
93 >   user as the functionality is embedded in the implementation of the IStatement
94 >   interface. Three new functions are defined:
95 >
96 >    procedure AddToBatch;
97 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
98 >    procedure CancelBatch;
99 >    function GetBatchCompletion: IBatchCompletion;
100 >    function GetBatchRowLimit: integer;
101 >    procedure SetBatchRowLimit(aLimit: integer);
102 >
103 >   Also
104 >
105 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
106 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
107 >
108 >   For more information see the User Guide.
109 >
110 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
111 >   provided with the EIBInterBaseError now include all three parts.
112 >
113 > 5. Firebird.pas and include files updated to Firebird 4.0.0
114 >
115 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
116 >   Returns SQL Statement type as a text string;
117 >
118 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
119 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
120 >
121 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
122 >
123 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
124 >   typo in FB30Statement.pas that caused an unknown parameter error.
125 >
126 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
127 >
128 > 1. Imported (Firebird) constants updated for Firebird 4.
129 >
130 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
131 >
132 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
133 >
134 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
135 >
136 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
137 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
138 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
139 >   type safe access to the Firebird IMaster interface and avoids the need to turn
140 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
141 >
142 > 6. New IFirebirdAPI Calls:
143 >    function HasLocalTZDB: boolean;
144 >    function HasTimeZoneSupport: boolean;
145 >    function HasExtendedTZSupport: boolean;
146 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
147 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
148 >
149 > 7. New IAttachment Calls:
150 >    function HasDecFloatSupport: boolean;
151 >    function GetTimeZoneServices: ITimeZoneServices;
152 >    function HasTimeZoneSupport: boolean;
153 >
154 > 8. New Interface ITimeZoneServices.
155 >
156 > 9. New ISQLData API Calls:
157 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
158 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
159 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
160 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
161 >    function GetAsUTCDateTime: TDateTime;
162 >    function GetAsBCD: tBCD;
163 >
164 > 10. New ISQLParam API Calls
165 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
166 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

177 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
178 >    procedure SetAsBcd(aValue: tBCD);
179 >
180 > 11. New IArray API Calls
181 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
182 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

201 >      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
202 >    This is used to add a parameter block item by the string equivalent of its
203 >    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
204 >

210 >
211 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
212 >
213 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
214 >   with a Firebrid 3 client library.
215 >
216 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
217 >    If a client library path is not explicitly provided and the FIREBIRD environment
218 >    variable is set then the directory given by this variable and any 'lib' subdirectory
219 >    are searched for the Firebird client library. Only if none is found, is the default
220 >    client library used.
221 >
222 > 3.  IUtil.FormatStatus now used to format error messages when using new API
223 >
224 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
225 >
226 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
227 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
228 >    that the byte length corresponds to the number of characters specified for the column.
229 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
230 >    correct behaviour but may affect some implementations that relied upon automatic
231 >    trimming of trailing white space.
232 >
233 > 6.  New IFirebirdAPI Calls:
234 >      function GetClientMajor: integer;
235 >      function GetClientMinor: integer;
236 >
237 > 7.  IColumnMetaData and IArrayMetaData: new method
238 >      function GetCharSetWidth: integer;
239 >
240 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
241 >
242 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
243 >   case sensitive
244 >
245 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
246 >
247 > 3. New API Calls:
248 >        IColumnMetaData.GetStatement
249 >        IColumnMetaData.GetTransaction
250 >        ISQLData.GetStrDataLength
251 >        IResults.GetStatement
252 >        IAttachment.OpenBlob (using Blob metadata)
253 >        IAttachment.OpenArray (using array metadata)
254 >
255 > 4. FBMessages: removal of unused messages
256 >
257 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
258 >
259 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
260 >
261 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
262 >
263 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
264 >   where the second character of the parameter name is a numeric.
265 >
266 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
267 >   This returns the isc_version connection information as one or more lines.
268 >   This is the same information as returned by isql with the -z option.
269 >
270 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
271 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
272 >   compiler option then the Firebird 3 API is no longer compiled in.
273 >
274 > 4. IColumnMetaData: new method.
275 >
276 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
277 >                        dfDateTime,   {SQL DATETIME}
278 >                        dfTime);
279 >
280 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
281 >
282 >   This returns the max. number of characters returned by the "AsString" method
283 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
284 >
285 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
286 >     CaseSensitiveParams: boolean = false
287 >
288 >   If this argument is set to true then SQL parameter names are assumed to be case
289 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
290 >   sensitive name.
291 >
292 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
293 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
294 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
295 >   using .AsString.

301 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
302 >
303 > 2. Restrict IsMultiThread check to Unix only for compatibility with
304 >   https://bugs.freepascal.org/view.php?id=30535
305 >
306 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
307 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
308 >   and processing internal parameters as statement parameters.
309 >
310 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
311 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
312 >
313 > 5. New function added to IB.pas
