2 >
3 > 1. Imported (Firebird) constants updated for Firebird 4.
4 >
5 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
6 >
7 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
8 >
9 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
10 >
11 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
12 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
13 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
14 >   type safe access to the Firebird IMaster interface and avoids the need to turn
15 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
16 >
17 > 6. New IFirebirdAPI Calls:
18 >    function HasLocalTZDB: boolean;
19 >    function HasTimeZoneSupport: boolean;
20 >    function HasExtendedTZSupport: boolean;
21 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
22 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
23 >
24 > 7. New IAttachment Calls:
25 >    function HasDecFloatSupport: boolean;
26 >    function GetTimeZoneServices: ITimeZoneServices;
27 >    function HasTimeZoneSupport: boolean;
28 >
29 > 8. New Interface ITimeZoneServices.
30 >
31 > 9. New ISQLData API Calls:
32 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
33 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
34 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
35 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
36 >    function GetAsUTCDateTime: TDateTime;
37 >    function GetAsBCD: tBCD;
38 >
39 > 10. New ISQLParam API Calls
40 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
41 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

87 >
88 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
89 >   with a Firebrid 3 client library.
90 >
91 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
92 >    If a client library path is not explicitly provided and the FIREBIRD environment
93 >    variable is set then the directory given by this variable and any 'lib' subdirectory
94 >    are searched for the Firebird client library. Only if none is found, is the default
95 >    client library used.
96 >
97 > 3.  IUtil.FormatStatus now used to format error messages when using new API
98 >
99 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
100 >
101 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
102 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
103 >    that the byte length corresponds to the number of characters specified for the column.
104 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
105 >    correct behaviour but may affect some implementations that relied upon automatic
106 >    trimming of trailing white space.
107 >
108 > 6.  New IFirebirdAPI Calls:
109 >      function GetClientMajor: integer;
110 >      function GetClientMinor: integer;
111 >
112 > 7.  IColumnMetaData and IArrayMetaData: new method
113 >      function GetCharSetWidth: integer;
114 >

116 >
117 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
118 >   case sensitive
119 >
120 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
121 >
122 > 3. New API Calls:
123 >        IColumnMetaData.GetStatement
124 >        IColumnMetaData.GetTransaction
125 >        ISQLData.GetStrDataLength
126 >        IResults.GetStatement
127 >        IAttachment.OpenBlob (using Blob metadata)
128 >        IAttachment.OpenArray (using array metadata)
129 >
130 > 4. FBMessages: removal of unused messages
131 >
132 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
133 >
134 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.

137  
138   1. Fix a problem with the SQL parameter parser that failed to recognise parameters
139     where the second character of the parameter name is a numeric.
# Line 7 | Line 142 | FBINTF Change Log  version          (1.1
142     This returns the isc_version connection information as one or more lines.
143     This is the same information as returned by isql with the -z option.
144  
145 + 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
146 +   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
147 +   compiler option then the Firebird 3 API is no longer compiled in.
148 +
149 + 4. IColumnMetaData: new method.
150 +
151 +   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
152 +                        dfDateTime,   {SQL DATETIME}
153 +                        dfTime);
154 +
155 +   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
156 +
157 +   This returns the max. number of characters returned by the "AsString" method
158 +   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
159 +
160 + 5. Additional argument for IAttachment.PrepareWithNamedParameters -
161 +     CaseSensitiveParams: boolean = false
162 +
163 +   If this argument is set to true then SQL parameter names are assumed to be case
164 +   sensitive and must be referenced (using ISQLParams.ByName) using the case
165 +   sensitive name.
166 +
167 + 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
168 +   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
169 +   .AsCurrency) and then subsequently to update the value to a non-numeric string
170 +   using .AsString.
171 +
172 +
