1 > FBINTF Change Log  version          (1.2-1 Build 12546) Wed, 09 Jun 2021 11:57:29 +0100
2 >
3 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
4 >   typo in FB30Statement.pas that caused an unknown parameter error.
5 >
6 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
7 >
8 > 1. Imported (Firebird) constants updated for Firebird 4.
9 >
10 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
11 >
12 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
13 >
14 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
15 >
16 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
17 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
18 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
19 >   type safe access to the Firebird IMaster interface and avoids the need to turn
20 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
21 >
22 > 6. New IFirebirdAPI Calls:
23 >    function HasLocalTZDB: boolean;
24 >    function HasTimeZoneSupport: boolean;
25 >    function HasExtendedTZSupport: boolean;
26 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
27 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
28 >
29 > 7. New IAttachment Calls:
30 >    function HasDecFloatSupport: boolean;
31 >    function GetTimeZoneServices: ITimeZoneServices;
32 >    function HasTimeZoneSupport: boolean;
33 >
34 > 8. New Interface ITimeZoneServices.
35 >
36 > 9. New ISQLData API Calls:
37 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
38 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
39 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
40 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
41 >    function GetAsUTCDateTime: TDateTime;
42 >    function GetAsBCD: tBCD;
43 >
44 > 10. New ISQLParam API Calls
45 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
46 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
47 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
48 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
49 >    function GetAsUTCDateTime: TDateTime;
50 >    function GetAsBCD: tBCD;
51 >    function GetStatement: IStatement;
52 >    function GetTransaction: ITransaction;
53 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
54 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
55 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
56 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
57 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
58 >    procedure SetAsBcd(aValue: tBCD);
59 >
60 > 11. New IArray API Calls
61 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
62 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
63 >    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

84 >
85 > 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
86 >      function getParamTypeName: AnsiString;

90 >
91 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
92 >
93 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
94 >   with a Firebrid 3 client library.
95 >
96 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
97 >    If a client library path is not explicitly provided and the FIREBIRD environment
98 >    variable is set then the directory given by this variable and any 'lib' subdirectory
99 >    are searched for the Firebird client library. Only if none is found, is the default
100 >    client library used.
101 >
102 > 3.  IUtil.FormatStatus now used to format error messages when using new API
103 >
104 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
105 >
106 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
107 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
108 >    that the byte length corresponds to the number of characters specified for the column.
109 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
110 >    correct behaviour but may affect some implementations that relied upon automatic
111 >    trimming of trailing white space.
112 >
113 > 6.  New IFirebirdAPI Calls:
114 >      function GetClientMajor: integer;
115 >      function GetClientMinor: integer;
116 >
117 > 7.  IColumnMetaData and IArrayMetaData: new method
118 >      function GetCharSetWidth: integer;
119 >
120 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
121 >
122 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
123 >   case sensitive
124 >
125 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
126 >
127 > 3. New API Calls:
128 >        IColumnMetaData.GetStatement
129 >        IColumnMetaData.GetTransaction
130 >        ISQLData.GetStrDataLength
131 >        IResults.GetStatement
132 >        IAttachment.OpenBlob (using Blob metadata)
133 >        IAttachment.OpenArray (using array metadata)
134 >
135 > 4. FBMessages: removal of unused messages
136 >
137 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
138 >
139 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
140 >
141 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
142 >
143 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
144 >   where the second character of the parameter name is a numeric.
145 >
146 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
147 >   This returns the isc_version connection information as one or more lines.
148 >   This is the same information as returned by isql with the -z option.
149 >
150 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
151 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
152 >   compiler option then the Firebird 3 API is no longer compiled in.
153 >
154 > 4. IColumnMetaData: new method.
155 >
156 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
157 >                        dfDateTime,   {SQL DATETIME}
158 >                        dfTime);
159 >
160 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
161 >
162 >   This returns the max. number of characters returned by the "AsString" method
163 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
164 >
165 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
166 >     CaseSensitiveParams: boolean = false
167 >
168 >   If this argument is set to true then SQL parameter names are assumed to be case
169 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
170 >   sensitive name.
171 >
172 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
173 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
174 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
175 >   using .AsString.

180 >
181 > 1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
182 >
183 > 2. Restrict IsMultiThread check to Unix only for compatibility with
184 >   https://bugs.freepascal.org/view.php?id=30535
185 >
186 > 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
187 >   named parameters and is intended to avoid problems with (e.g.) Execute Block
188 >   and processing internal parameters as statement parameters.
189 >
190 > 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
191 >   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
192 >
193 > 5. New function added to IB.pas
194 >
195 >   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
196 >
197 >   This allows a Firebird Library to be loaded from an explicit path. use the
198 >   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
199 >   the library. It is possible to load Firebird libraries from different locations
200 >   simultaneously, each with a distinct IFirebirdAPI.
