2 >
3 > 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
4 >
5 > 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
6 >   will now be encoded inline (i.e. as part of the parameter buffer) if they are
7 >   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
8 >   separate server interaction. This is intended as a performance optimisation.
9 >
10 >   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
11 >   IAttachment interface functions:
12 >
13 >    function GetInlineBlobLimit: integer;
14 >    procedure SetInlineBlobLimit(limit: integer);
15 >
16 > 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
17 >   user as the functionality is embedded in the implementation of the IStatement
18 >   interface. Three new functions are defined:
19 >
20 >    procedure AddToBatch;
21 >    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
22 >    procedure CancelBatch;
23 >    function GetBatchCompletion: IBatchCompletion;
24 >    function GetBatchRowLimit: integer;
25 >    procedure SetBatchRowLimit(aLimit: integer);
26 >
27 >   Also
28 >
29 >    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
30 >    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
31 >
32 >   For more information see the User Guide.
33 >
34 > 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
35 >   provided with the EIBInterBaseError now include all three parts.
36 >
37 > 5. Firebird.pas and include files updated to Firebird 4.0.0
38 >
39 > 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
40 >   Returns SQL Statement type as a text string;
41 >
42 > 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
43 >   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
44 >
45 > FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
46 >
47 > 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
48 >   typo in FB30Statement.pas that caused an unknown parameter error.
49 >
50 > FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
51 >
52 > 1. Imported (Firebird) constants updated for Firebird 4.
53 >
54 > 2. Firebird.pas from Firebird 4 integrated into source code tree.
55 >
56 > 3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types.
57 >
58 > 4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision.
59 >
60 > 5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider.
61 >   QueryInterface may be used to coerce this interface from IFirebirdAPI. The
62 >   interface provides a single method "function GetIMasterIntf: IMaster". This provides
63 >   type safe access to the Firebird IMaster interface and avoids the need to turn
64 >   off object checks when coercing "function GetIMaster: TObject" to IMaster.
65 >
66 > 6. New IFirebirdAPI Calls:
67 >    function HasLocalTZDB: boolean;
68 >    function HasTimeZoneSupport: boolean;
69 >    function HasExtendedTZSupport: boolean;
70 >    procedure SQLDecFloatEncode(aValue: tBCD; SQLType: cardinal; bufptr: PByte);
71 >    function SQLDecFloatDecode(SQLType: cardinal; scale: integer; bufptr: PByte): tBCD;
72 >
73 > 7. New IAttachment Calls:
74 >    function HasDecFloatSupport: boolean;
75 >    function GetTimeZoneServices: ITimeZoneServices;
76 >    function HasTimeZoneSupport: boolean;
77 >
78 > 8. New Interface ITimeZoneServices.
79 >
80 > 9. New ISQLData API Calls:
81 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
82 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
83 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
84 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;
85 >    function GetAsUTCDateTime: TDateTime;
86 >    function GetAsBCD: tBCD;
87 >
88 > 10. New ISQLParam API Calls
89 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
90 >    procedure GetAsDateTime(var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
91 >    procedure GetAsTime(var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;

94 >    function GetAsBCD: tBCD;
95 >    function GetStatement: IStatement;
96 >    function GetTransaction: ITransaction;
97 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
98 >    procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
99 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
100 >    procedure SetAsDateTime(aValue: TDateTime; aTimeZone: AnsiString); overload;
101 >    procedure SetAsUTCDateTime(aUTCTime: TDateTime);
102 >    procedure SetAsBcd(aValue: tBCD);
103 >
104 > 11. New IArray API Calls
105 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID); overload;
106 >    procedure GetAsDateTime(index: array of integer; var aDateTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString); overload;
107 >    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezoneID: TFBTimeZoneID; OnDate: TDateTime); overload;
108 >    procedure GetAsTime(index: array of integer; var aTime: TDateTime; var dstOffset: smallint; var aTimezone: AnsiString; OnDate: TDateTime); overload;

134 >
135 > FBINTF Change Log  version          (1.1-6 Build 12237) Tue, 21 Jul 2020 08:54:21 +0100
136 >
137 > 1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API
138 >   with a Firebrid 3 client library.
139 >
140 > 2. Linux Only: FIREBIRD environment variable is now checked when loading the client library.
141 >    If a client library path is not explicitly provided and the FIREBIRD environment
142 >    variable is set then the directory given by this variable and any 'lib' subdirectory
143 >    are searched for the Firebird client library. Only if none is found, is the default
144 >    client library used.
145 >
146 > 3.  IUtil.FormatStatus now used to format error messages when using new API
147 >
148 > 4.  Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer.
149 >
150 > 5.  SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is
151 >    returned using GetAsString and the string codepage is UTF8, the string is truncated so
152 >    that the byte length corresponds to the number of characters specified for the column.
153 >    SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is
154 >    correct behaviour but may affect some implementations that relied upon automatic
155 >    trimming of trailing white space.
156 >
157 > 6.  New IFirebirdAPI Calls:
158 >      function GetClientMajor: integer;
159 >      function GetClientMinor: integer;
160 >
161 > 7.  IColumnMetaData and IArrayMetaData: new method
162 >      function GetCharSetWidth: integer;
163 >
164 > FBINTF Change Log  version          (1.1-5 Build 12022) Fri, 17 Apr 2020 10:35:55 +0100
165 >
166 > 1. ISQLParams.GetHasCaseSensitiveParams added. Returns true if param names are
167 >   case sensitive
168 >
169 > 2. Single line SQL comments starting with '--' are now recognised by SQL Parser.
170 >
171 > 3. New API Calls:
172 >        IColumnMetaData.GetStatement
173 >        IColumnMetaData.GetTransaction
174 >        ISQLData.GetStrDataLength
175 >        IResults.GetStatement
176 >        IAttachment.OpenBlob (using Blob metadata)
177 >        IAttachment.OpenArray (using array metadata)
178 >
179 > 4. FBMessages: removal of unused messages
180 >
181 > 5. TFBArray.Create (2nd case): ensure that FFirebirdClientAPI is correctly set.
182 >
183 > 6. TIBSQLStatementType: SQLSavePoint added to end of enumeration.
184 >
185 > FBINTF Change Log  version          (1.1-4 Build 11515)  Fri, 28 Dec 2018 10:04:19 +0000
186 >
187 > 1. Fix a problem with the SQL parameter parser that failed to recognise parameters
188 >   where the second character of the parameter name is a numeric.
189 >
190 > 2. New method for IAttachment: procedure getFBVersion(version: TStrings);
191 >   This returns the isc_version connection information as one or more lines.
192 >   This is the same information as returned by isql with the -z option.
193 >
194 > 3. If -dFIREBIRD3APIONLY is used as a compiler option then the legacy Firebird API
195 >   is no longer compiled in. Likewise, if -dLEGACYFIREBIRDAPIONLY is used as a
196 >   compiler option then the Firebird 3 API is no longer compiled in.
197 >
198 > 4. IColumnMetaData: new method.
199 >
200 >   TIBDateTimeFormats = (dfTimestamp, {SQL TIMESTAMP}
201 >                        dfDateTime,   {SQL DATETIME}
202 >                        dfTime);
203 >
204 >   function GetDateTimeStrLength(DateTimeFormat: TIBDateTimeFormats): integer;
205 >
206 >   This returns the max. number of characters returned by the "AsString" method
207 >   when the SQL type of the column is respectively TIMESTAMP, DATETIME or TIME.
208 >
209 > 5. Additional argument for IAttachment.PrepareWithNamedParameters -
210 >     CaseSensitiveParams: boolean = false
211 >
212 >   If this argument is set to true then SQL parameter names are assumed to be case
213 >   sensitive and must be referenced (using ISQLParams.ByName) using the case
214 >   sensitive name.
215 >
216 > 6. Bug fix: when setting a query parameter, it is now possible, when the parameter
217 >   is of type VarChar or Char to set the parameter to a numeric value (e.g. using
218 >   .AsCurrency) and then subsequently to update the value to a non-numeric string
219 >   using .AsString.

224  
225   1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary
226  
227 + 2. Restrict IsMultiThread check to Unix only for compatibility with
228 +   https://bugs.freepascal.org/view.php?id=30535
229 +
230 + 3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with
231 +   named parameters and is intended to avoid problems with (e.g.) Execute Block
232 +   and processing internal parameters as statement parameters.
233 +
234 + 4. New interface IFirebirdLibrary provides access to the underlying firebird DLL
235 +   or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI.
236 +
237 + 5. New function added to IB.pas
238 +
239 +   function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary
240 +
241 +   This allows a Firebird Library to be loaded from an explicit path. use the
242 +   IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using
243 +   the library. It is possible to load Firebird libraries from different locations
244 +   simultaneously, each with a distinct IFirebirdAPI.
