2 >
3 > 1. IBUtils.FormatTimeZoneOffset A zero offset now includes a preceding '+' sign.
4 >
5 > 2. TFBStatement.DoJournaling now exits immediately if journaling is not active. The
6 >   motivation for this is to avoid calling the Firebird API function 'getInfo'
7 >   unnecesarily. This function can return an error if an incompatible parameter type was
8 >   applied to the statement and hence can confuse resolving the bug. Note: a
9 >   specific case is in (e.g.) OpenCursorAtStart method when the array of const includes a
10 >   TDateTime. In this case, the param is set to a floating point type rather than
11 >   a Firebird datetime (array of const loses the distinction).
12 >
13 > 3. TFBAttachment.SetParameters. if an attempt is made to set a parameter with a float
14 >   value, the metadata type is checked to see if the parameter is a Date/Time type. If so then
15 >   the value is assumed to be a TDateTime and the parameter is set using the AsDateTime
16 >   property. Otherwise, the value is assumed to be a floating point type and the AsDouble
17 >   property is used to set the property. This avoids the specific example given above.

20 >
21 > 1. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error
22 >   checks for range checking.
23 >
24 > 2. FB25Client: In GetIBMessage, fb_interpret is now called multiple times such that
25 >   any additional error information is decoded.
26 >
27 > 3. FB25Statement: When changing a param type from Blob sub_type 1 to SQL_TEXT or SQL_VARYING
28 >   charsetid is now preserved and size is set to default blob size. Now aligns with
29 >   FB3 and later.
30 >
31 > 4. DDL and DML string literals are now explicitly set to the connection character
32 >   set rather than the default character set provided by the compiler.
33 >
34 > 5. General tidy up of transliteration functions, now centralised in IBUtils. FPC testing
35 >   now makes use of the RTL fpwidestring unit for support of international character
36 >   sets.
37 >
38 > 6. Database exception handling (see section 9.3 in user guide).
39 >    * For FB3 and later API: Connection Character set now applied to message returned
40 >      by fb_interpret and message then transliterated if necessary to the system character set.
41 >    * For Legacy API: The message character set is guessed as UTF8 unless invalid
42 >      UTF8 characters found when connection character set is assumed. Message then
43 >      transliterated if necessary to system character set.
44 >      Note: this difference of behaviour is because legacy API presents exception messages
45 >      "as is", while FB3 server attempts to transliterate to connection character set.

47 > FBINTF Change Log  version          (1.4-0 Build 14011) Sat, 05 Aug 2023 11:09:09 +0100
48 >
49 > 1. Support package fbudr added for support of User Defined Routines (UDRs), and package
50 >   fbudrtestbed for client side debugging of UDR libraries.
51 >
52 > 2. Package layout changed with introduction of udr support. IB*.pas files moved from
53 >    root directory to "client". IBHeader moved to "Client".
54 >
55 > 3. Delphi packages: all packages now compile .dcp and .bpi files to either
56 >   fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing
57 >   fbintf.dcp and fbintf.bpi files from other locations.
58 >
59 > 4. Client side journaling support added. Interface changes
60 >   IAttachment
61 >    function JournalingActive: boolean;
62 >    function GetJournalOptions: TJournalOptions;
63 >    function StartJournaling(aJournalLogFile: AnsiString): integer; overload;
64 >    function StartJournaling(aJournalLogFile: AnsiString; Options: TJournalOptions): integer; overload;
65 >    function StartJournaling(S: TStream; Options: TJournalOptions): integer; overload;
66 >    procedure StopJournaling(RetainJournal: boolean);
67 >
68 > 5. Transactions may now be given a local transaction name:
69 >   IFirebirdAPI
70 >     function StartTransaction(Attachments: array of IAttachment;
71 >             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
72 >             TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit;
73 >             aName: AnsiString=''): ITransaction; overload;
74 >     function StartTransaction(Attachments: array of IAttachment;
75 >             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
76 >             TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit;
77 >             aName: AnsiString=''): ITransaction; overload;
78 >
79 >   IAttachment
80 >    function StartTransaction(TPB: array of byte; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
81 >    function StartTransaction(TPB: ITPB; DefaultCompletion: TTransactionCompletion=taCommit): ITransaction; overload;
82 >    function StartTransaction(TPB: array of byte;
83 >                              DefaultCompletion: TTransactionCompletion=taCommit;
84 >                              aName: AnsiString=''): ITransaction; overload;
85 >    function StartTransaction(TPB: ITPB;
86 >                              DefaultCompletion: TTransactionCompletion=taCommit;
87 >                              aName: AnsiString=''): ITransaction; overload;
88 >
89 >  ITransaction
90 >    function GetTransactionName: AnsiString;
91 >    procedure SetTransactionName(aValue: AnsiString);
92 >
93 > 6. Additional Transaction information
94 >     ITPB.function AsText: AnsiString; {Returns TPB as a text string}
95 >
96 >   ITransaction
97 >     function GetDefaultCompletion: TTransactionCompletion;
98 >     function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction}
99 >
100 > 7. New IAttachment helper functions
101 >     function HasTable(aTableName: AnsiString): boolean;
102 >     function HasFunction(aFunctionName: AnsiString): boolean;
103 >     function HasProcedure(aProcName: AnsiString): boolean;
104 >     function GetAttachmentID: integer;
105 >     function GetCharSetID: integer;
106 >
107 > 8. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size
108 >   will be allocated for batch operations.
109 >
110 > 9. IStatement, IColumnMetaData and ISQLParam all now consistently provide:
111 >    function GetStatement: IStatement;
112 >    function GetTransaction: ITransaction;
113 >    function GetAttachment: IAttachment;
114 >
115 > 10. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted
116 >    interfaces.
117 >
118 > 11. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric
119 >    and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam
120 >    functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation
121 >    of numerics without loss of precision.
122 >
123 > 12. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric.
124 >
125 > 13. ISQLParams new method "Clear"
126 >
127 > 14. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first
128 >    request rather than on attachment connect.
129 >
130 > 15. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the
131 >    fact that SQLCodes are soon to be deprecated. In the future, the other options
132 >    will be silently ignored if SQLCode support is not present in the Firebird
133 >    Client library.
134 >
135 > 16. ITransaction changes Rollback and Commit from procedures to functions:
136 >      function Commit(Force: boolean=false): TTrCompletionState;
137 >      function Rollback(Force: boolean=false): TTrCompletionState;
138 >
139 >    Specifically, this is to allow the functions to report back a failed commit or
140 >    rollback when Force = true. In the case, the transaction handle has been
141 >    released, while the transaction remains in limbo.
142 >
143 > 17. IAttachment ExecImmediate.
144 >    When the transaction parameters are provided as an array of const and the
145 >    statement fails, the transaction is rolledback (forced) before the exception
146 >    is raised.
147 >
148 > 18. In Firebird 3 and later API: the status vector is now a thread var, as was
149 >    already the case with the legacy API. Avoids problems when calling underlying
150 >    Firebird API in multiple threads.
151 >
152 > 19. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility
153 >    reasons.
154 >
155 > 20. IDBInformation.DecodeVersionString now supported isc_info_firebird_version.
156 >
157 > 21. TSQLXMLReader: handle 'blob' as a reserved word
158 >
159 > 22. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString).
160 >
161 >
162 > FBINTF Change Log  version          (1.3-3 Build 12935) Mon, 06 Dec 2021 23:17:13 +0000
163 >
164 > 1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit.
165 >
166 > 2. Remove constraint in IAttachment.HasScollableCursors that returned false when
167 >   using remote protocol. Scrollable cursors with remote database expected to
168 >   be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return
169 >   a not supported error.
170 >
171 > 3. IStatement: new function;
172 >    TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable);
173 >    TStatementFlags = set of TStatementFlag;
174 >    function GetFlags: TStatementFlags;
175 >
176 > 4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards
177 >   compatibility.
178 >   In Firebird 5, Update..Returning may returns multiple rows and hence the statemen
179 >   type changes from ExecProcedure to Select. So that ExecuteQuery can continue
180 >   to be used with Update...Retruning statements that return a singleton row,
181 >   instead of raising an exception when ExecuteQuery is used with a (SELECT) statement,
182 >   it will open the cursor and return the first row only.
183 >
184 > 5. ITransaction: new functions:
185 >    function GetIsReadOnly: boolean;
186 >    function GetTransactionID: integer;
187 >    function GetTrInformation(Requests: array of byte): ITrInformation; overload;
188 >    function GetTrInformation(Request: byte): ITrInformation; overload;
189 >
190 >   The latter two return the Transaction Information block. The first two extract
191 >   information the Transaction Information block
192 >
193 > 6. New function TSQLTokeniser.ReadCharacters
194 >   Used internally.
195 >
196 > 7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains
197 >   parameter placeholders instead of named parameters.
198 >
199 > 8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying
200 >   transaction handle is now ignored if Rollback/Commit is called with Force=true
201 >
202 > 9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now
203 >   used to get an IBError Message instead of isc_interprete.
204 >
205 > 10. Internal tidyup. Native code now used for decoding integers and the events
206 >    buffer. Avoids dependencies on fbclient functions isc_portable_integer,
207 >    isc_event_block and isc_event_counts.
208 >
209 > 11. New IAttachment function
210 >     function GetAttachmentID: integer;
211 >
212 > 12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30
213 >    subclasses to enable UDR support.

217   1. TFBClientAPI.GetProcAddr. Add check for nil reference.
218  
# Line 29 | Line 243 | FBINTF Change Log  version          (1.3
243     Note: ISQLParam metadata can change after a parameter value has been set e.g when
244     setting a VARCHAR column to an integer value.
245  
246 + 8. IStatement: can now set cursor name when opening a cursor. New overloaded method:
247 +    procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload;
248 +   also IAttachment:
249 +    function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload;
250 +    function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload;
251 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
252 +                       aSQLDialect: integer; GenerateParamNames: boolean=false;
253 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
254 +    function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString;
255 +                       GenerateParamNames: boolean=false;
256 +                       CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload;
257 +
258 + 9. Support for scrollable cursors added. New/updated methods:
259 +   IAttachment:
260 +    function HasScollableCursors: boolean;
261 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
262 +                             Scrollable: boolean=false): IResultSet; overload;
263 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
264 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
265 +                             params: array of const): IResultSet; overload;
266 +    function OpenCursor(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false;
267 +                             params: array of const): IResultSet; overload;
268 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; Scrollable: boolean;
269 +                             params: array of const): IResultSet; overload;
270 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer;
271 +                             Scrollable: boolean=false): IResultSet; overload;
272 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
273 +    function OpenCursorAtStart(transaction: ITransaction; sql: AnsiString; Scrollable: boolean;
274 +                             params: array of const): IResultSet; overload;
275 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean=false): IResultSet; overload;
276 +    function OpenCursorAtStart(sql: AnsiString; Scrollable: boolean;
277 +                             params: array of const): IResultSet; overload;
278 +   IStatement:
279 +     function OpenCursor(Scrollable: boolean; CursorName: AnsiString =''; aTransaction: ITransaction=nil): IResultSet; overload;
280 +   IResultSet:
281 +    function FetchPrior: boolean; {fetch previous record}
282 +    function FetchFirst:boolean; {fetch first record}
283 +    function FetchLast: boolean; {fetch last record}
284 +    function FetchAbsolute(position: Integer): boolean; {fetch record by its absolute position in result set}
285 +    function FetchRelative(offset: Integer): boolean; {fetch record by position relative to current}
286 +    function IsBof: boolean;
287 +
288 + 10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers.
289 +
290 + 11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This
291 +    may be noticeable when a line separator occurs inside quoted text. The quoted text
292 +    output by the tokeniser will now use the platform specific lineEnding regardless
293 +    of whether the input uses the CRLF or LF as a line separator.
294 +
295 + 12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only)
296 +
