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. |
| 18 |
> |
|
| 19 |
> |
4. IBHeader (legacy interface only) Definition of Start_Transaction changed to use |
| 20 |
> |
varargs - win64 compatibility issue. |
| 21 |
> |
|
| 22 |
> |
5. FB25Blob: last parameter of call to isc_blob_lookup_desc is now set to nil. This |
| 23 |
> |
avoids memory corruption with Firebird 4 when using the legacy interface. |

> |
1. FBSQLData: ensure that TResults.getSQLData and TResults.GetData use same error |
| 28 |
> |
checks for range checking. |
| 29 |
> |
|
| 30 |
> |
2. FB25Client: In GetIBMessage, fb_interpret is now called multiple times such that |
| 31 |
> |
any additional error information is decoded. |
| 32 |
> |
|
| 33 |
> |
3. FB25Statement: When changing a param type from Blob sub_type 1 to SQL_TEXT or SQL_VARYING |
| 34 |
> |
charsetid is now preserved and size is set to default blob size. Now aligns with |
| 35 |
> |
FB3 and later. |
| 36 |
> |
|
| 37 |
> |
4. DDL and DML string literals are now explicitly set to the connection character |
| 38 |
> |
set rather than the default character set provided by the compiler. |
| 39 |
> |
|
| 40 |
> |
5. General tidy up of transliteration functions, now centralised in IBUtils. FPC testing |
| 41 |
> |
now makes use of the RTL fpwidestring unit for support of international character |
| 42 |
> |
sets. |
| 43 |
> |
|
| 44 |
> |
6. Database exception handling (see section 9.3 in user guide). |
| 45 |
> |
* For FB3 and later API: Connection Character set now applied to message returned |
| 46 |
> |
by fb_interpret and message then transliterated if necessary to the system character set. |
| 47 |
> |
* For Legacy API: The message character set is guessed as UTF8 unless invalid |
| 48 |
> |
UTF8 characters found when connection character set is assumed. Message then |
| 49 |
> |
transliterated if necessary to system character set. |
| 50 |
> |
Note: this difference of behaviour is because legacy API presents exception messages |
| 51 |
> |
"as is", while FB3 server attempts to transliterate to connection character set. |

1. Support package fbudr added for support of User Defined Routines (UDRs), and package |
| 56 |
> |
fbudrtestbed for client side debugging of UDR libraries. |
| 57 |
> |
|
| 58 |
> |
2. Package layout changed with introduction of udr support. IB*.pas files moved from |
| 59 |
> |
root directory to "client". IBHeader moved to "Client". |
| 60 |
> |
|
| 61 |
> |
3. Delphi packages: all packages now compile .dcp and .bpi files to either |
| 62 |
> |
fbintf\Win32\Debug or fbintf\Win64\Debug by default. Please remove any pre-existing |
| 63 |
> |
fbintf.dcp and fbintf.bpi files from other locations. |
| 64 |
> |
|
| 65 |

IAttachment |
| 67 |

IFirebirdAPI |
| 76 |

6. Additional Transaction information |
| 100 |
> |
ITPB.function AsText: AnsiString; {Returns TPB as a text string} |
| 101 |
> |
|
| 102 |
> |
ITransaction |
| 103 |
> |
function GetDefaultCompletion: TTransactionCompletion; |
| 104 |
> |
function GetJournalingActive(attachment: IAttachment): boolean; {attachment must be specified when multi-database transaction} |
| 105 |
> |
|
| 106 |
> |
7. New IAttachment helper functions |
| 107 |
> |
function HasTable(aTableName: AnsiString): boolean; |
| 108 |
> |
function HasFunction(aFunctionName: AnsiString): boolean; |
| 109 |
> |
function HasProcedure(aProcName: AnsiString): boolean; |
| 110 |
> |
function GetAttachmentID: integer; |
| 111 |
> |
function GetCharSetID: integer; |
| 112 |
> |
|
| 113 |
> |
8. IStatement: if the BatchRowLimit is set to maxint, the maximum possible buffer size |
| 114 |
> |
will be allocated for batch operations. |
| 115 |
> |
|
| 116 |
> |
9. IStatement, IColumnMetaData and ISQLParam all now consistently provide: |
| 117 |
> |
function GetStatement: IStatement; |
| 118 |
> |
function GetTransaction: ITransaction; |
| 119 |
> |
function GetAttachment: IAttachment; |
| 120 |
> |
|
| 121 |
> |
10. Internal: a more disciplined approach to the handling of Firebird.IReferenceCounted |
| 122 |
> |
interfaces. |
| 123 |
> |
|
| 124 |
> |
11. New interface type: IFBNumeric. IFBNumeric is implemented in the unit FBNumeric |
| 125 |
> |
and concentrates all handling of Fixed Point numbers. New ISQLItem and ISQLParam |
| 126 |
> |
functions getAsNumeric and setAsNumeric allow for direct retrival and manipulation |
| 127 |
> |
of numerics without loss of precision. |
| 128 |
> |
|
| 129 |
> |
12. TryStrToNumeric and NumericToDouble moved from IBUtils to FBNumeric. |
| 130 |
> |
|
| 131 |
> |
13. ISQLParams new method "Clear" |
| 132 |
> |
|
| 133 |
> |
14. Connection Info (e.g. ODS Version, Remote Protocol) now retrieved on first |
| 134 |
> |
request rather than on attachment connect. |
| 135 |
> |
|
| 136 |
> |
15. IStatus.IBDataBaseErrorMessages now defaults to [ShowIBMessage]. This reflects the |
| 137 |
> |
fact that SQLCodes are soon to be deprecated. In the future, the other options |
| 138 |
> |
will be silently ignored if SQLCode support is not present in the Firebird |
| 139 |
> |
Client library. |
| 140 |
> |
|
| 141 |
> |
16. ITransaction changes Rollback and Commit from procedures to functions: |
| 142 |
> |
function Commit(Force: boolean=false): TTrCompletionState; |
| 143 |
> |
function Rollback(Force: boolean=false): TTrCompletionState; |
| 144 |
> |
|
| 145 |
> |
Specifically, this is to allow the functions to report back a failed commit or |
| 146 |
> |
rollback when Force = true. In the case, the transaction handle has been |
| 147 |
> |
released, while the transaction remains in limbo. |
| 148 |
> |
|
| 149 |
> |
17. IAttachment ExecImmediate. |
| 150 |
> |
When the transaction parameters are provided as an array of const and the |
| 151 |
> |
statement fails, the transaction is rolledback (forced) before the exception |
| 152 |
> |
is raised. |
| 153 |
> |
|
| 154 |
> |
18. In Firebird 3 and later API: the status vector is now a thread var, as was |
| 155 |
> |
already the case with the legacy API. Avoids problems when calling underlying |
| 156 |
> |
Firebird API in multiple threads. |
| 157 |
> |
|
| 158 |
> |
19. IBUtils: TSQLXMLReader: "string" type changed to "AnsiString" for compatibility |
| 159 |
> |
reasons. |
| 160 |
> |
|
| 161 |
> |
20. IDBInformation.DecodeVersionString now supported isc_info_firebird_version. |
| 162 |
> |
|
| 163 |
> |
21. TSQLXMLReader: handle 'blob' as a reserved word |
| 164 |
> |
|
| 165 |
> |
22. ISQLParam.SetAsVariant now accepts a vartype of varUString (UnicodeString). |

|
| 170 |
> |
1. Fix compile error with fpc trunk (3.3.1 and later), due to type change to tzname in "unix" unit. |
| 171 |
> |
|
| 172 |
> |
2. Remove constraint in IAttachment.HasScollableCursors that returned false when |
| 173 |
> |
using remote protocol. Scrollable cursors with remote database expected to |
| 174 |
> |
be support for Firebird 4.0.1 onwards. Note: Firebird 4.0.0 will return |
| 175 |
> |
a not supported error. |
| 176 |
> |
|
| 177 |
> |
3. IStatement: new function; |
| 178 |
> |
TStatementFlag = (stHasCursor,stRepeatExecute,stScrollable); |
| 179 |
> |
TStatementFlags = set of TStatementFlag; |
| 180 |
> |
function GetFlags: TStatementFlags; |
| 181 |
> |
|
| 182 |
> |
4. Revised behaviour for IStatement.ExecuteQuery in order to preserve backwards |
| 183 |
> |
compatibility. |
| 184 |
> |
In Firebird 5, Update..Returning may returns multiple rows and hence the statemen |
| 185 |
> |
type changes from ExecProcedure to Select. So that ExecuteQuery can continue |
| 186 |
> |
to be used with Update...Retruning statements that return a singleton row, |
| 187 |
> |
instead of raising an exception when ExecuteQuery is used with a (SELECT) statement, |
| 188 |
> |
it will open the cursor and return the first row only. |
| 189 |
> |
|
| 190 |
> |
5. ITransaction: new functions: |
| 191 |
> |
function GetIsReadOnly: boolean; |
| 192 |
> |
function GetTransactionID: integer; |
| 193 |
> |
function GetTrInformation(Requests: array of byte): ITrInformation; overload; |
| 194 |
> |
function GetTrInformation(Request: byte): ITrInformation; overload; |
| 195 |
> |
|
| 196 |
> |
The latter two return the Transaction Information block. The first two extract |
| 197 |
> |
information the Transaction Information block |
| 198 |
> |
|
| 199 |
> |
6. New function TSQLTokeniser.ReadCharacters |
| 200 |
> |
Used internally. |
| 201 |
> |
|
| 202 |
> |
7. IStatement: GetProcessedSQL bug fix. No longer raises and error if SQL contains |
| 203 |
> |
parameter placeholders instead of named parameters. |
| 204 |
> |
|
| 205 |
> |
8. ITransaction (Firebird 3 and later): An exception raised when freeing an underlying |
| 206 |
> |
transaction handle is now ignored if Rollback/Commit is called with Force=true |
| 207 |
> |
|
| 208 |
> |
9. Tidy up of exception handling code. Under the legacy API, fb_interpret is now |
| 209 |
> |
used to get an IBError Message instead of isc_interprete. |
| 210 |
> |
|
| 211 |
> |
10. Internal tidyup. Native code now used for decoding integers and the events |
| 212 |
> |
buffer. Avoids dependencies on fbclient functions isc_portable_integer, |
| 213 |
> |
isc_event_block and isc_event_counts. |
| 214 |
> |
|
| 215 |
> |
11. New IAttachment function |
| 216 |
> |
function GetAttachmentID: integer; |
| 217 |
> |
|
| 218 |
> |
12. Internal changes to TFBClientAPI, TFBAttachment and TFBTransaction and TFB30 |
| 219 |
> |
subclasses to enable UDR support. |
| 220 |
> |
|

FBINTF Change Log version (1.3-2 Build 12889) Sun, 24 Oct 2021 13:49:28 +0100 |
| 222 |
> |
|
| 223 |
> |
1. TFBClientAPI.GetProcAddr. Add check for nil reference. |
| 224 |
> |
|
| 225 |
> |
2. IStatement: new methods: |
| 226 |
> |
procedure SetStaleReferenceChecks(Enable:boolean); {default true} |
| 227 |
> |
function GetStaleReferenceChecks: boolean; |
| 228 |
> |
|
| 229 |
> |
In previous versions, stale reference checks were always enabled. This allows the |
| 230 |
> |
user to disable them on a per statement basis. Note this can risk out-of-date |
| 231 |
> |
statement BLR. See User Guide. |
| 232 |
> |
|
| 233 |
> |
3. IBUtils: TSQLwithNamedParamsTokeniser now recognises a CASE...END block within a |
| 234 |
> |
stored procedure and hence avoids replacing named parameters within a containing |
| 235 |
> |
BEGIN..END block. |
| 236 |
> |
|
| 237 |
> |
4. ISQLParam: using a string value to set an integer field with a scale factor of |
| 238 |
> |
zero is now treated as a special case to avoid the risk of floating point |
| 239 |
> |
rounding errors affecting pure integers. |
| 240 |
> |
|
| 241 |
> |
5. ISQLParam: Review and tidy-up of SetAsString for numeric types. |
| 242 |
> |
|
| 243 |
> |
6. ISQLParam is now subclassed from IParamMetaData, which provides access to the mutable |
| 244 |
> |
SQL Parameter metadata (methods moved from ISQLParam). |
| 245 |
> |
|
| 246 |
> |
7. ISQLParam: new method |
| 247 |
> |
function getColMetadata: IParamMetaData; |
| 248 |
> |
This instance of IParamMetaData returns the original column metadata which is unmutable. |
| 249 |
> |
Note: ISQLParam metadata can change after a parameter value has been set e.g when |
| 250 |
> |
setting a VARCHAR column to an integer value. |
| 251 |
> |
|
| 252 |
> |
8. IStatement: can now set cursor name when opening a cursor. New overloaded method: |
| 253 |
> |
procedure Prepare(CursorName: AnsiString; aTransaction: ITransaction=nil); overload; |
| 254 |
> |
also IAttachment: |
| 255 |
> |
function Prepare(transaction: ITransaction; sql: AnsiString; aSQLDialect: integer; CursorName: AnsiString=''): IStatement; overload; |
| 256 |
> |
function Prepare(transaction: ITransaction; sql: AnsiString; CursorName: AnsiString=''): IStatement; overload; |
| 257 |
> |
function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; |
| 258 |
> |
aSQLDialect: integer; GenerateParamNames: boolean=false; |
| 259 |
> |
CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; |
| 260 |
> |
function PrepareWithNamedParameters(transaction: ITransaction; sql: AnsiString; |
| 261 |
> |
GenerateParamNames: boolean=false; |
| 262 |
> |
CaseSensitiveParams: boolean = false; CursorName: AnsiString=''): IStatement; overload; |
| 263 |
> |
|
| 264 |
> |
9. Support for scrollable cursors added. New/updated methods: |
| 265 |
> |
IAttachment: |
| 266 |
> |
function HasScollableCursors: boolean; |
| 267 |
> |

| 292 |
> |
function IsBof: boolean; |
| 293 |
> |
|
| 294 |
> |
10. IArray: tidyup of SetAsString method to ensure correct handling of fixed point numbers. |
| 295 |
> |
|
| 296 |
> |
11. IBUtils: TSQLTokeniser. CRLF now combined by low level parser into sqltEOL token. This |
| 297 |
> |
may be noticeable when a line separator occurs inside quoted text. The quoted text |
| 298 |
> |
output by the tokeniser will now use the platform specific lineEnding regardless |
| 299 |
> |
of whether the input uses the CRLF or LF as a line separator. |
| 300 |
> |
|
| 301 |
> |
12. IStatement, IResultsSet: Support for scrollable cursors added (note: local databases only) |

1. Integer decodes in information blocks (e.g. IDBInfoItem) widened from 32 bit to 64-bit integers. |
| 307 |
> |
|
| 308 |
> |
2. Support for inline blob encoding. Blob values pass using the "SetAsString" method |
| 309 |
> |
will now be encoded inline (i.e. as part of the parameter buffer) if they are |
| 310 |
> |
shorter than a pre-set limit. Longer values continue to be saved as blobs as a |
| 311 |
> |
separate server interaction. This is intended as a performance optimisation. |
| 312 |
> |
|
| 313 |
> |
The pre-set limit defaults to 8192 bytes and can be inspected/modified using the new |
| 314 |
> |
IAttachment interface functions: |
| 315 |
> |
|
| 316 |
> |
function GetInlineBlobLimit: integer; |
| 317 |
> |
procedure SetInlineBlobLimit(limit: integer); |
| 318 |
> |
|
| 319 |
> |
3. Support for Firebird 4 IBatch interface added. This is largely transparent to the API |
| 320 |
> |
user as the functionality is embedded in the implementation of the IStatement |
| 321 |
> |
interface. Three new functions are defined: |
| 322 |
> |
|
| 323 |
> |
procedure AddToBatch; |
| 324 |
> |
function ExecuteBatch(aTransaction: ITransaction=nil): IBatchCompletion; |
| 325 |
> |
procedure CancelBatch; |
| 326 |
> |
function GetBatchCompletion: IBatchCompletion; |
| 327 |
> |
function GetBatchRowLimit: integer; |
| 328 |
> |
procedure SetBatchRowLimit(aLimit: integer); |
| 329 |
> |
|
| 330 |
> |
Also |
| 331 |
> |
|
| 332 |
> |
function IsInBatchMode: boolean; {true after call to execute(eaDefer)} |
| 333 |
> |
function HasBatchMode: boolean; {true if and only if IBatch Supported} |
| 334 |

4. Default error message contents. Now aligned with User Guide section 10.2 i.e. error messages |
| 338 |
> |
provided with the EIBInterBaseError now include all three parts. |
| 339 |
> |
|
| 340 |

5. Firebird.pas and include files updated to Firebird 4.0.0 |
| 341 |

|
| 342 |

6. New IStatement method: function GetSQLStatementTypeName: AnsiString; |
| 343 |
> |
Returns SQL Statement type as a text string; |
| 344 |
> |
|
| 345 |
> |
7. ISQLData.AsInteger and AsInt64 now use "Round" to convert a float field to |
| 346 |

an integer instead of "trunc". This is for compatibility with TFloatField.AsInteger. |

1. Imported (Firebird) constants updated for Firebird 4. |
| 356 |
> |
|
| 357 |
> |
2. Firebird.pas from Firebird 4 integrated into source code tree. |
| 358 |
> |
|
| 359 |
> |
3. Added Support for TIMETAMP WITH TIME ZONE and TIME WITH TIME ZONE data types. |
| 360 |

|
| 361 |
> |
4. Added Support for SQL_DEC16, SQL_DEC34 and extended NUMERIC precision. |
| 362 |
> |
|
| 363 |
> |
5. New unit 'FBClientLib.pas' added and provides new interface IFBIMasterProvider. |
| 364 |
> |
QueryInterface may be used to coerce this interface from IFirebirdAPI. The |
| 365 |
> |
interface provides a single method "function GetIMasterIntf: IMaster". This provides |
| 366 |
> |
type safe access to the Firebird IMaster interface and avoids the need to turn |

off object checks when coercing "function GetIMaster: TObject" to IMaster. |

1. GetImplementationVersion now correctly returns '3.0' for Firebird 3 API |
| 441 |
> |
with a Firebrid 3 client library. |
| 442 |
> |
|
| 443 |
> |
2. Linux Only: FIREBIRD environment variable is now checked when loading the client library. |
| 444 |
> |
If a client library path is not explicitly provided and the FIREBIRD environment |
| 445 |
> |
variable is set then the directory given by this variable and any 'lib' subdirectory |
| 446 |
> |
are searched for the Firebird client library. Only if none is found, is the default |
| 447 |
> |
client library used. |
| 448 |
> |
|
| 449 |
> |
3. IUtil.FormatStatus now used to format error messages when using new API |
| 450 |
> |
|
| 451 |
> |
4. Fixed Array SDL: array_desc_scale now correctly encoded as a signed integer. |
| 452 |
> |
|
| 453 |
> |
5. SQL_TEXT handling changed. When the value of an SQL_TEXT (i.e. fixed width string) column is |
| 454 |
> |
returned using GetAsString and the string codepage is UTF8, the string is truncated so |
| 455 |
> |
that the byte length corresponds to the number of characters specified for the column. |
| 456 |
> |
SQL_TEXT strings are no longer automatically trimmed to remove all trailing white space. This is |
| 457 |
> |
correct behaviour but may affect some implementations that relied upon automatic |
| 458 |
> |
trimming of trailing white space. |
| 459 |

| 491 |
> |
where the second character of the parameter name is a numeric. |

2. New method for IAttachment: procedure getFBVersion(version: TStrings); |

| 513 |
> |
CaseSensitiveParams: boolean = false |
| 514 |

|
| 515 |
> |
If this argument is set to true then SQL parameter names are assumed to be case |

| 517 |

sensitive name. |

6. Bug fix: when setting a query parameter, it is now possible, when the parameter |
| 520 |
> |
is of type VarChar or Char to set the parameter to a numeric value (e.g. using |
| 521 |
> |
.AsCurrency) and then subsequently to update the value to a non-numeric string |

1. DARWIN only syntax error: fix missing semi-colon in TFBClientAPI.LoadIBLibrary |
| 529 |
|
|
| 530 |
+ |
2. Restrict IsMultiThread check to Unix only for compatibility with |

3. New SQL Tokeniser added to IBUtils. This is used to pre-process SQL with |
| 534 |
+ |
named parameters and is intended to avoid problems with (e.g.) Execute Block |
| 535 |
+ |
and processing internal parameters as statement parameters. |
| 536 |
+ |
|
| 537 |
+ |
4. New interface IFirebirdLibrary provides access to the underlying firebird DLL |
| 538 |
+ |
or shared object. Available via a new member (GetFBLibrary) of IFirebirdAPI. |
| 539 |
+ |
|
| 540 |

|
| 542 |
+ |
function LoadFBLibrary(aLibPathName: string): IFirebirdLibrary |
| 543 |
+ |

| 545 |
+ |
IFirebirdLibrary.GetFirebirdAPI member function to get the Firebird API using |
