1 + FBINTF Change Log  version          (1.4-0 Build 12952) Tue, 07 Dec 2021 11:53:46 +0000
2 +
3 + 1. Client side journaling support added. Interface changes
4 +   IAttachment
5 +    function JournalingActive: boolean;
6 +    function GetJournalOptions: TJournalOptions;
7 +    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
8 +    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
9 +    procedure StopJournaling(RetainJournal: boolean);
10 +
11 + 2. Transactions may now be given a local transaction name:
12 +   IFirebirdAPI
13 +     function StartTransaction(Attachments: array of IAttachment;
14 +             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
15 +             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
16 +             aName: AnsiString=''): ITransaction; overload;
17 +     function StartTransaction(Attachments: array of IAttachment;
18 +             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
19 +             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
20 +             aName: AnsiString=''): ITransaction; overload;
21 +
22 +   IAttachment
23 +    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
24 +    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
25 +    function StartTransaction(TPB: array of byte;
26 +                              DefaultCompletion: TTransactionCompletion=taCommit;
27 +                              aName: AnsiString=''): ITransaction; overload;
28 +    function StartTransaction(TPB: ITPB;
29 +                              DefaultCompletion: TTransactionCompletion=taCommit;
30 +                              aName: AnsiString=''): ITransaction; overload;
31 +
32 +  ITransaction
33 +    function GetTransactionName: AnsiString;
34 +    procedure SetTransactionName(aValue: AnsiString);
35 +
36 + 3. Additional Transaction information
37 +     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
38 +
39 +   ITransaction
40 +     function GetDefaultCompletion: TTransactionCompletion;
41 +     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
42 +
43 + 4. New IAttachment helper functions
44 +     function HasTable(aTableName: AnsiString): boolean;
45 +     function GetAttachmentID: integer;
46 +
47 + FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
48 +
49 + 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
50 +
51 + 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
52 +   using remote protocol. Scrollable cursors with remote database expected to
53 +   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
54 +   a not supported error.
55 +
56 + 3. IStatement: new function;
57 +    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
58 +    TStatementFlags = set of TStatementFlag;
59 +    function GetFlags: TStatementFlags;
60 +
61 + 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
62 +   compatibility.
63 +   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
64 +   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
65 +   to be used with Update...Retruning statements that return a singleton row,
66 +   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
67 +   it will open the cursor and return the first row only.
68 +
69 + 5. ITransaction: new functions:
70 +    function GetIsReadOnly: boolean;
71 +    function GetTransactionID: integer;
72 +    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
73 +    function GetTrInformation(Request: byte): ITrInformation; overload;
74 +
75 +   The latter two return the Transaction Information block. The first two extract
76 +   information the Transaction Information block
77 +
78 + 6. New function TSQLTokeniser.ReadCharacters
79 +   Used internally.
80 +
81 + 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
82 +   parameter placeholders instead of named parameters.
83 +
84 + 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
85 +   transaction handle is now ignored if Rollback/Commit is called with Force=true
86 +
87 + FBINTF Change Log  version          (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100
88 +
89 + 1. TFBClientAPI.GetProcAddr. Add check for nil reference.
90 +
91 + 2. IStatement: new methods:
92 +    procedure SetStaleReferenceChecks(Enable:boolean); {default true}
93 +    function GetStaleReferenceChecks: boolean;
94 +
95 +   In previous versions, stale reference checks were always enabled. This allows the
96 +   user to disable them on a per statement basis. Note this can risk out-of-date
97 +   statement BLR. See User Guide.
98 +
99 + 3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a
100 +   stored procedure and hence avoids replacing named parameters within a containing
101 +   BEGIN..END block.
102 +
103 + 4. ISQLParam: using a string value to set an integer field with a scale factor of
104 +   zero is now treated as a special case to avoid the risk of floating point
105 +   rounding errors affecting pure integers.
106 +
107 + 5. ISQLParam:  Review and tidy-up of SetAsString for numeric types.
108 +
109 + 6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable
110 +   SQL Parameter metadata (methods moved from ISQLParam).
111 +
112 + 7. ISQLParam: new method
113 +     function getColMetadata: IParamMetaData;
114 +   This instance of IParamMetaData returns the original column metadata which is unmutable.
115 +   Note: ISQLParam metadata can change after a parameter value has been set e.g when
116 +   setting a VARCHAR column to an integer value.
117 +
118 + 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
119 +    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
120 +   also IAttachment:
121 +    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
122 +    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
123 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
124 +                       aSQLDialect: integer; GenerateParamNames: boolean=false;
125 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
126 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
127 +                       GenerateParamNames: boolean=false;
128 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
129 +
130 + 9. Support for scrollable cursors added. New/updated methods:
131 +   IAttachment:
132 +    function HasScollableCursors: boolean;
133 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
134 +                             Scrollable: boolean=false): IResultSet; overload;
135 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
136 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
137 +                             params: array of const): IResultSet; overload;
138 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
139 +                             params: array of const): IResultSet; overload;
140 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
141 +                             params: array of const): IResultSet; overload;
142 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
143 +                             Scrollable: boolean=false): IResultSet; overload;
144 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
145 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
146 +                             params: array of const): IResultSet; overload;
147 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
148 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
149 +                             params: array of const): IResultSet; overload;
150 +   IStatement:
151 +     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
152 +   IResultSet:
153 +    function FetchPrior: boolean; {fetch previous record}
154 +    function FetchFirst:boolean; {fetch first record}
155 +    function FetchLast: boolean; {fetch last record}
156 +    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
157 +    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
158 +    function IsBof: boolean;
159 +
160 + 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
161 +
162 + 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
163 +    may be noticeable when a line separator occurs inside quoted text. The quoted text
164 +    output by the tokeniser will now use the platform specific lineEnding regardless
165 +    of whether the input uses the CRLF or LF as a line separator.
166 +
167 + 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
168 +
169 +
170 + FBINTF Change Log  version          (1.3-1 Build 12776) Mon, 23 Aug 2021 11:09:33 +0100
171 +
172 + 1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers.
173 +
174 + 2. Support for inline blob encoding. Blob values pass using the "SetAsString" method
175 +   will now be encoded inline (i.e. as part of the parameter buffer) if they are
176 +   shorter than a pre-set limit. Longer values continue to be saved as blobs as a
177 +   separate server interaction. This is intended as a performance optimisation.
178 +
179 +   The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new
180 +   IAttachment interface functions:
181 +
182 +    function GetInlineBlobLimit: integer;
183 +    procedure SetInlineBlobLimit(limit: integer);
184 +
185 + 3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API
186 +   user as the functionality is embedded in the implementation of the IStatement
187 +   interface. Three new functions are defined:
188 +
189 +    procedure AddToBatch;
190 +    function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion;
191 +    procedure CancelBatch;
192 +    function GetBatchCompletion: IBatchCompletion;
193 +    function GetBatchRowLimit: integer;
194 +    procedure SetBatchRowLimit(aLimit: integer);
195 +
196 +   Also
197 +
198 +    function IsInBatchMode: boolean;        {true after call to execute(eaDefer)}
199 +    function HasBatchMode: boolean;         {true if and only if IBatch Supported}
200 +
201 +   For more information see the User Guide.
202 +
203 + 4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages
204 +   provided with the EIBInterBaseError now include all three parts.
205 +
206 + 5. Firebird.pas and include files updated to Firebird 4.0.0
207 +
208 + 6. New IStatement method: function GetSQLStatementTypeName: AnsiString;
209 +   Returns SQL Statement type as a text string;
210 +
211 + 7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to
212 +   an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger.
213 +
214 + FBINTF Change Log  version          (1.2-1 Build 12552) Wed, 09 Jun 2021 13:05:40 +0100
215 +
216 + 1. Big fix for Firebird 4.0. A internal change in Firebird 4.0.0 from RC1 flushed out a
217 +   typo in FB30Statement.pas that caused an unknown parameter error.
218 +
219   FBINTF Change Log  version          (1.2-0 Build 12520) Fri, 19 Feb 2021 13:27:23 +0000
220  
221   1. Imported (Firebird) constants updated for Firebird 4.
