1 + FBINTF Change Log  version          (1.3-2 Build 12806) Wed, 06 Oct 2021 09:07:03 +0100
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 Note this can risk out-of-date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 + FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
18 +
19 + 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
20 +
21 + 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
22 +   will now be encoded inline (i.e. as part of the parameter buffer) if they are
23 +   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
24 +   separate server interaction. This is intended as a performance optimisation.
25 +
26 +   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
27 +   IAttachment interface functions:
28 +
29 +    function GetInlineBlobLimit: integer;
30 +    procedure SetInlineBlobLimit(limit: integer);
31 +
32 + 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
33 +   user as the functionality is embedded in the implementation of the IStatement
34 +   interface. Three new functions are defined:
35 +
36 +    procedure AddToBatch;
37 +    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
38 +    procedure CancelBatch;
39 +    function GetBatchCompletion: IBatchCompletion;
40 +    function GetBatchRowLimit: integer;
41 +    procedure SetBatchRowLimit(aLimit: integer);
42 +
43 +   Also
44 +
45 +    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
46 +    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
47 +
48 +   For more information see the User Guide.
49 +
50 + 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
51 +   provided with the EIBInterBaseError now include all three parts.
52 +
53 + 5. Firebird.pas and include files updated to Firebird 4.0.0
54 +
55 + 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
56 +   Returns SQL Statement type as a text string;
57 +
58 + 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
59 +   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
60 +
61 + FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
62 +
63 + 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
64 +   typo in FB30Statement.pas that caused an unknown parameter error.
65 +
66 + FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
67 +
68 + 1. Imported (Firebird) constants updated for Firebird 4.
69 +
70 + 2. Firebird.pas from Firebird 4 integrated into source code tree.
71 +
72 + 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
73 +
74 + 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
75 +
76 + 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
77 +   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
78 +   interface provides a single method "function GetIMasterIntf: IMaster". This provides
79 +   type safe access to the Firebird IMaster interface and avoids the need to turn
80 +   off object checks when coercing "function GetIMaster: TObject" to IMaster.
81 +
82 + 6. New IFirebirdAPI Calls:
83 +    function HasLocalTZDB: boolean;
84 +    function HasTimeZoneSupport: boolean;
85 +    function HasExtendedTZSupport: boolean;
86 +    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
87 +    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
88 +
89 + 7. New IAttachment Calls:
90 +    function HasDecFloatSupport: boolean;
91 +    function GetTimeZoneServices: ITimeZoneServices;
92 +    function HasTimeZoneSupport: boolean;
93 +
94 + 8. New Interface ITimeZoneServices.
95 +
96 + 9. New ISQLData API Calls:
97 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
98 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
99 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
100 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
101 +    function GetAsUTCDateTime: TDateTime;
102 +    function GetAsBCD: tBCD;
103 +
104 + 10. New ISQLParam API Calls
105 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
106 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
107 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
108 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
109 +    function GetAsUTCDateTime: TDateTime;
110 +    function GetAsBCD: tBCD;
111 +    function GetStatement: IStatement;
112 +    function GetTransaction: ITransaction;
113 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
114 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
115 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
116 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
117 +    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
118 +    procedure SetAsBcd(aValue: tBCD);
119 +
120 + 11. New IArray API Calls
121 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
122 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
123 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
124 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
125 +    function GetAsUTCDateTime(index: array of integer): TDateTime;
126 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
127 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
128 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
129 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
130 +
131 + 12. Utility functions in IBUtils
132 +    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
133 +              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
134 +    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
135 +    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
136 +    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
137 +    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
138 +    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
139 +
140 + 13. IDPB, ITPB and ISPB: new interface method
141 +      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
142 +    This is used to add a parameter block item by the string equivalent of its
143 +    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
144 +
145 + 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
146 +      function getParamTypeName: AnsiString;
147 +
148 + 15. fb_shutdown now called before unloading Firebird library. This can avoid a
149 +     SIGEVENT error when a programme using the embeded server is unloaded.
150 +
151 + FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
152 +
153 + 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
154 +   with a Firebrid 3 client library.
155 +
156 + 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
157 +    If a client library path is not explicitly provided and the FIREBIRD environment
158 +    variable is set then the directory given by this variable and any 'lib' subdirectory
159 +    are searched for the Firebird client library. Only if none is found, is the default
160 +    client library used.
161 +
162 + 3.  IUtil.FormatStatus now used to format error messages when using new API
163 +
164 + 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
165 +
166 + 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
167 +    returned using GetAsString and the string codepage is UTF8, the string is truncated so
168 +    that the byte length corresponds to the number of characters specified for the column.
169 +    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
170 +    correct behaviour but may affect some implementations that relied upon automatic
171 +    trimming of trailing white space.
172 +
173 + 6.  New IFirebirdAPI Calls:
174 +      function GetClientMajor: integer;
175 +      function GetClientMinor: integer;
176 +
177 + 7.  IColumnMetaData and IArrayMetaData: new method
178 +      function GetCharSetWidth: integer;
179 +
180 + FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
181 +
182 + 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
183 +   case sensitive
184 +
185 + 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
186 +
187 + 3. New API Calls:
188 +        IColumnMetaData.GetStatement
189 +        IColumnMetaData.GetTransaction
190 +        ISQLData.GetStrDataLength
191 +        IResults.GetStatement
192 +        IAttachment.OpenBlob (using Blob metadata)
193 +        IAttachment.OpenArray (using array metadata)
194 +
195 + 4. FBMessages: removal of unused messages
196 +
197 + 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
198 +
199 + 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
200 +
201 + FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
202 +
203 + 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
204 +   where the second character of the parameter name is a numeric.
205 +
206 + 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
207 +   This returns the isc_version connection information as one or more lines.
208 +   This is the same information as returned by isql with the -z option.
209 +
210 + 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
211 +   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
212 +   compiler option then the Firebird 3 API is no longer compiled in.
213 +
214 + 4. IColumnMetaData: new method.
215 +
216 +   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
217 +                        dfDateTime,   {SQL DATETIME}
218 +                        dfTime);
219 +
220 +   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
221 +
222 +   This returns the max. number of characters returned by the "AsString" method
223 +   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
224 +
225 + 5. Additional argument for IAttachment.PrepareWithNamedParameters -
226 +     CaseSensitiveParams: boolean = false
227 +
228 +   If this argument is set to true then SQL parameter names are assumed to be case
229 +   sensitive and must be referenced (using ISQLParams.ByName) using the case
230 +   sensitive name.
231 +
232 + 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
233 +   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
234 +   .AsCurrency) and then subsequently to update the value to a non-numeric string
235 +   using .AsString.
236 +
237 +
238 +
