1 + FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
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;
42 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
43 +    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
44 +    function GetAsUTCDateTime: TDateTime;
45 +    function GetAsBCD: tBCD;
46 +    function GetStatement: IStatement;
47 +    function GetTransaction: ITransaction;
48 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
49 +    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
50 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
51 +    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
52 +    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
53 +    procedure SetAsBcd(aValue: tBCD);
54 +
55 + 11. New IArray API Calls
56 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
57 +    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
58 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
59 +    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
60 +    function GetAsUTCDateTime(index: array of integer): TDateTime;
61 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
62 +    procedure SetAsDateTime(index: array of integer; aValue: TDateTime; aTimeZone: AnsiString); overload;
63 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
64 +    procedure SetAsTime(index: array of integer; aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
65 +
66 + 12. Utility functions in IBUtils
67 +    function ParseDateTimeTZString(aDateTimeStr: Ansistring; var aDateTime: TDateTime;
68 +              var aTimezone: AnsiString; aFormatSettings: TFormatSettings; TimeOnly: boolean=false): boolean;
69 +    procedure FBDecodeTime(aTime: TDateTime; var Hour, Minute, Second: word; var DeciMillisecond: cardinal);
70 +    function FBEncodeTime(Hour, Minute, Second, DeciMillisecond: cardinal): TDateTime;
71 +    function FBFormatDateTime(fmt: AnsiString; aDateTime: TDateTime): AnsiString;
72 +    function FormatTimeZoneOffset(EffectiveTimeOffsetMins: integer): AnsiString;
73 +    function DecodeTimeZoneOffset(TZOffset: AnsiString; var dstOffset: integer): boolean;
74 +
75 + 13. IDPB, ITPB and ISPB: new interface method
76 +      function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
77 +    This is used to add a parameter block item by the string equivalent of its
78 +    symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'
79 +
80 + 14. IDPBItem/ITPBItem/ISPBItem: new interface method:
81 +      function getParamTypeName: AnsiString;
82 +
83 + 15. fb_shutdown now called before unloading Firebird library. This can avoid a
84 +     SIGEVENT error when a programme using the embeded server is unloaded.
85 +
86 + FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
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 +
115 + FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
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.
135 +
136 + FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
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.
140 +
141 + 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
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 +
173 +
