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 Note this can risk out-of-date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 > 4. ISQLParam: using a string value to set an integer field with a scale factor of
18 >   zero is now treated as a special case to avoid the risk of floating point
19 >   rounding errors affecting pure integers.
20 >
21 > 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
22 >
23 > 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
24 >   SQL Parameter metadata (methods moved from ISQLParam).
25 >
26 > 7. ISQLParam: new method
27 >     function getColMetadata: IParamMetaData;
28 >   This instance of IParamMetaData returns the original column metadata which is unmutable.
29 >   Note: ISQLParam metadata can change after a parameter value has been set e.g when
30 >   setting a VARCHAR column to an integer value.
31 >
32 > 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
33 >    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
34 >   also IAttachment:
35 >    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
36 >    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
37 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
38 >                       aSQLDialect: integer; GenerateParamNames: boolean=false;
39 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
40 >    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
41 >                       GenerateParamNames: boolean=false;
42 >                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
43 >
44 > 9. Support for scrollable cursors added. New/updated methods:
45 >   IAttachment:
46 >    function HasScollableCursors: boolean;
47 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
48 >                             Scrollable: boolean=false): IResultSet; overload;
49 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
50 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
51 >                             params: array of const): IResultSet; overload;
52 >    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
53 >                             params: array of const): IResultSet; overload;
54 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
55 >                             params: array of const): IResultSet; overload;
56 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
57 >                             Scrollable: boolean=false): IResultSet; overload;
58 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
59 >    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
60 >                             params: array of const): IResultSet; overload;
61 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
62 >    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
63 >                             params: array of const): IResultSet; overload;
64 >   IStatement:
65 >     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
66 >   IResultSet:
67 >    function FetchPrior: boolean; {fetch previous record}
68 >    function FetchFirst:boolean; {fetch first record}
69 >    function FetchLast: boolean; {fetch last record}
70 >    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
71 >    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
72 >    function IsBof: boolean;

77 >
78 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
79 >
80 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
81 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
82 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
83 >   separate server interaction. This is intended as a performance optimisation.
84 >
85 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
86 >   IAttachment interface functions:
87 >
88 >    function GetInlineBlobLimit: integer;
89 >    procedure SetInlineBlobLimit(limit: integer);
90 >
91 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
92 >   user as the functionality is embedded in the implementation of the IStatement
93 >   interface. Three new functions are defined:
94 >
95 >    procedure AddToBatch;
96 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
97 >    procedure CancelBatch;
98 >    function GetBatchCompletion: IBatchCompletion;
99 >    function GetBatchRowLimit: integer;
100 >    procedure SetBatchRowLimit(aLimit: integer);
101 >
102 >   Also
103 >
104 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
105 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
106 >
107 >   For more information see the User Guide.
108 >
109 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
110 >   provided with the EIBInterBaseError now include all three parts.
111 >
112 > 5. Firebird.pas and include files updated to Firebird 4.0.0
113 >
114 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
115 >   Returns SQL Statement type as a text string;
116 >
117 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
118 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
119 >
120 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
121 >
122 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
123 >   typo in FB30Statement.pas that caused an unknown parameter error.
124 >
125 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
126 >
127 > 1. Imported (Firebird) constants updated for Firebird 4.
128 >
129 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
130 >
131 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
132 >
133 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
134 >
135 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
136 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
137 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
138 >   type safe access to the Firebird IMaster interface and avoids the need to turn
139 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
140 >
141 > 6. New IFirebirdAPI Calls:
142 >    function HasLocalTZDB: boolean;
143 >    function HasTimeZoneSupport: boolean;
144 >    function HasExtendedTZSupport: boolean;
145 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
146 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
147 >
148 > 7. New IAttachment Calls:
149 >    function HasDecFloatSupport: boolean;
150 >    function GetTimeZoneServices: ITimeZoneServices;
151 >    function HasTimeZoneSupport: boolean;
152 >
153 > 8. New Interface ITimeZoneServices.
154 >
155 > 9. New ISQLData API Calls:
156 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
157 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
158 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
159 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
160 >    function GetAsUTCDateTime: TDateTime;
161 >    function GetAsBCD: tBCD;
162 >
163 > 10. New ISQLParam API Calls
164 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
165 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

176 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
177 >    procedure SetAsBcd(aValue: tBCD);
178 >
179 > 11. New IArray API Calls
180 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
181 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;

209 >
210 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
211 >
212 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
213 >   with a Firebrid 3 client library.
214 >
215 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
216 >    If a client library path is not explicitly provided and the FIREBIRD environment
217 >    variable is set then the directory given by this variable and any 'lib' subdirectory
218 >    are searched for the Firebird client library. Only if none is found, is the default
219 >    client library used.
220 >
221 > 3.  IUtil.FormatStatus now used to format error messages when using new API
222 >
223 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
224 >
225 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
226 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
227 >    that the byte length corresponds to the number of characters specified for the column.
228 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
229 >    correct behaviour but may affect some implementations that relied upon automatic
230 >    trimming of trailing white space.
231 >
232 > 6.  New IFirebirdAPI Calls:
233 >      function GetClientMajor: integer;
234 >      function GetClientMinor: integer;
235 >
236 > 7.  IColumnMetaData and IArrayMetaData: new method
237 >      function GetCharSetWidth: integer;
238 >
239 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100

246   3. New API Calls:
247          IColumnMetaData.GetStatement
248          IColumnMetaData.GetTransaction
249 <        ISQLData.GetStrLength
249 >        ISQLData.GetStrDataLength
250          IResults.GetStatement
251          IAttachment.OpenBlob (using Blob metadata)
252          IAttachment.OpenArray (using array metadata)
