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 Note this can risk out-of-date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;
73	>
74	>

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;

168	>	function GetAsUTCDateTime: TDateTime;
169	>	function GetAsBCD: tBCD;
170	>	function GetStatement: IStatement;
171	>	function GetTransaction: ITransaction;
172	>	procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
173	>	procedure SetAsTime(aValue: TDateTime; OnDate: TDateTime; aTimeZone: AnsiString); overload;
174	>	procedure SetAsDateTime(aValue: TDateTime; aTimeZoneID: TFBTimeZoneID); overload;
175	>	procedure SetAsDateTime(aValue: TDateTime; 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;

200	>	function AddByTypeName(ParamTypeName: AnsiString): IDPBItem/ITPBItem/ISPBItem;
201	>	This is used to add a parameter block item by the string equivalent of its
202	>	symbolic type name. e.g. DPB.AddByTypeName('isc_dpb_user_name').AsString := '...'

205	>	function getParamTypeName: AnsiString;
206	>

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	>
