1 + FBINTF Change Log  version          (1.3-2 Build 12798) Mon, 20 Sep 2021 12:42:46 +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 Note this can risk out-of-date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 + FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
14 +
15 + 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
16 +
17 + 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
18 +   will now be encoded inline (i.e. as part of the parameter buffer) if they are
19 +   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
20 +   separate server interaction. This is intended as a performance optimisation.
21 +
22 +   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
23 +   IAttachment interface functions:
24 +
25 +    function GetInlineBlobLimit: integer;
26 +    procedure SetInlineBlobLimit(limit: integer);
27 +
28 + 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
29 +   user as the functionality is embedded in the implementation of the IStatement
30 +   interface. Three new functions are defined:
31 +
32 +    procedure AddToBatch;
33 +    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
34 +    procedure CancelBatch;
35 +    function GetBatchCompletion: IBatchCompletion;
36 +    function GetBatchRowLimit: integer;
37 +    procedure SetBatchRowLimit(aLimit: integer);
38 +
39 +   Also
40 +
41 +    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
42 +    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
43 +
44 +   For more information see the User Guide.
45 +
46 + 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
47 +   provided with the EIBInterBaseError now include all three parts.
48 +
49 + 5. Firebird.pas and include files updated to Firebird 4.0.0
50 +
51 + 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
52 +   Returns SQL Statement type as a text string;
53 +
54 + 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
55 +   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
56 +
57 + FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
58 +
59 + 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
60 +   typo in FB30Statement.pas that caused an unknown parameter error.
61 +
62 + FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
63 +
64 + 1. Imported (Firebird) constants updated for Firebird 4.
65 +
66 + 2. Firebird.pas from Firebird 4 integrated into source code tree.
67 +
68 + 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
69 +
70 + 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
71 +
72 + 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
73 +   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
74 +   interface provides a single method "function GetIMasterIntf: IMaster". This provides
75 +   type safe access to the Firebird IMaster interface and avoids the need to turn
76 +   off object checks when coercing "function GetIMaster: TObject" to IMaster.
77 +
78 + 6. New IFirebirdAPI Calls:
79 +    function HasLocalTZDB: boolean;
80 +    function HasTimeZoneSupport: boolean;
81 +    function HasExtendedTZSupport: boolean;
82 +    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
83 +    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
84 +
85 + 7. New IAttachment Calls:
86 +    function HasDecFloatSupport: boolean;
87 +    function GetTimeZoneServices: ITimeZoneServices;
88 +    function HasTimeZoneSupport: boolean;
89 +
90 + 8. New Interface ITimeZoneServices.
91 +
92 + 9. New ISQLData API Calls:
93 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
94 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
95 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
96 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
97 +    function GetAsUTCDateTime: TDateTime;
98 +    function GetAsBCD: tBCD;
99 +
100 + 10. New ISQLParam API Calls
101 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
102 +    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
103 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
104 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
105 +    function GetAsUTCDateTime: TDateTime;
106 +    function GetAsBCD: tBCD;
107 +    function GetStatement: IStatement;
108 +    function GetTransaction: ITransaction;
109 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
110 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
111 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
112 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
113 +    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
114 +    procedure SetAsBcd(aValue: tBCD);
115 +
116 + 11. New IArray API Calls
117 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
118 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
119 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
120 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
121 +    function GetAsUTCDateTime(index: array of integer): TDateTime;
122 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
123 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
124 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
125 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
126 +
127 + 12. Utility functions in IBUtils
128 +    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
129 +              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
130 +    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
131 +    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
132 +    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
133 +    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
134 +    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
135 +
136 + 13. IDPB, ITPB and ISPB: new interface method
137 +      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
138 +    This is used to add a parameter block item by the string equivalent of its
139 +    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
140 +
141 + 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
142 +      function getParamTypeName: AnsiString;
143 +
144 + 15. fb_shutdown now called before unloading Firebird library. This can avoid a
145 +     SIGEVENT error when a programme using the embeded server is unloaded.
146 +
147 + FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
148 +
149 + 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
150 +   with a Firebrid 3 client library.
151 +
152 + 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
153 +    If a client library path is not explicitly provided and the FIREBIRD environment
154 +    variable is set then the directory given by this variable and any 'lib' subdirectory
155 +    are searched for the Firebird client library. Only if none is found, is the default
156 +    client library used.
157 +
158 + 3.  IUtil.FormatStatus now used to format error messages when using new API
159 +
160 + 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
161 +
162 + 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
163 +    returned using GetAsString and the string codepage is UTF8, the string is truncated so
164 +    that the byte length corresponds to the number of characters specified for the column.
165 +    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
166 +    correct behaviour but may affect some implementations that relied upon automatic
167 +    trimming of trailing white space.
168 +
169 + 6.  New IFirebirdAPI Calls:
170 +      function GetClientMajor: integer;
171 +      function GetClientMinor: integer;
172 +
173 + 7.  IColumnMetaData and IArrayMetaData: new method
174 +      function GetCharSetWidth: integer;
175 +
176 + FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
177 +
178 + 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
179 +   case sensitive
180 +
181 + 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
182 +
183 + 3. New API Calls:
184 +        IColumnMetaData.GetStatement
185 +        IColumnMetaData.GetTransaction
186 +        ISQLData.GetStrDataLength
187 +        IResults.GetStatement
188 +        IAttachment.OpenBlob (using Blob metadata)
189 +        IAttachment.OpenArray (using array metadata)
190 +
191 + 4. FBMessages: removal of unused messages
192 +
193 + 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
194 +
195 + 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
196 +
197 + FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
198 +
199 + 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
200 +   where the second character of the parameter name is a numeric.
201 +
202 + 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
203 +   This returns the isc_version connection information as one or more lines.
204 +   This is the same information as returned by isql with the -z option.
205 +
206 + 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
207 +   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
208 +   compiler option then the Firebird 3 API is no longer compiled in.
209 +
210 + 4. IColumnMetaData: new method.
211 +
212 +   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
213 +                        dfDateTime,   {SQL DATETIME}
214 +                        dfTime);
215 +
216 +   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
217 +
218 +   This returns the max. number of characters returned by the "AsString" method
219 +   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
220 +
221 + 5. Additional argument for IAttachment.PrepareWithNamedParameters -
222 +     CaseSensitiveParams: boolean = false
223 +
224 +   If this argument is set to true then SQL parameter names are assumed to be case
225 +   sensitive and must be referenced (using ISQLParams.ByName) using the case
226 +   sensitive name.
227 +
228 + 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
229 +   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
230 +   .AsCurrency) and then subsequently to update the value to a non-numeric string
231 +   using .AsString.
232 +
233 +
234 +
