ODBC_SQLGetDiagRec 


 

ODBC_SQLGetDiagRec ( handleType ; handleID ; recNb ; sqlState ; nativeError ; messageText ; TextLänge ) -> Funktionsergebnis 
Parameter Typ   Beschreibung
handleType  Lange Ganzzahl in Type of ID to pass to handleID
handleID  Lange Ganzzahl in Handle ID for the diagnostic data structure
recNb  Lange Ganzzahl in Indicates the status record from which information is sought. Status records are numbered from 1
sqlState  String in Five-character SQLSTATE code pertaining to the diagnostic record recNb
nativeError  Lange Ganzzahl in Native error code, specific to the data source
messageText  Text in Diagnostic message text string
TextLänge  Lange Ganzzahl in Length of the string returned in messageText
Funktionsergebnis  Lange Ganzzahl in Returns the result of the MS ODBC API function SQLGetDiagRec

The ODBC_SQLGetDiagRec command returns the current values of multiple fields of a diagnostic record that contains error, warning, and status information. Call this command any time one of the other 4D ODBC PRO commands does not return SQL_SUCCESS.

handleType defines the type of ID to pass to handleID, which can be one of the following:

ConstantDescription
SQL_HANDLE_ENVEnvironment ID
SQL_HANDLE_DBCConnection ID
SQL_HANDLE_STMTStatement ID
SQL_HANDLE_DESCDescriptor ID

handleID is a handle ID for the diagnostic data structure, of the type indicated by handleType. If handleType is SQL_HANDLE_ENV, this parameter is taken into account and the constant SQL_DEFAULT_ID can be then used.

handleID is the connectionID if handleType is equal to SQL_HANDLE_DBC. connectionID is a valid connection ID returned by ODBC_SQLAllocConnect and a connection must be established using the ODBC_SQLConnect command.

Otherwise, handleID is the stmtID, which is a valid statement ID returned by ODBC_SQLAllocStmt.

recNb indicates the status record from which information is sought. Status records are numbered from 1.

sqlState is the five-character SQLSTATE code pertaining to recNb. The first two characters indicate the class; the next three indicate the subclass. This value comes from the SQL_DIAG_SQLSTATE diagnostic field.

nativeError is the native error code specific to the data source, from the SQL_DIAG_NATIVE diagnostic field.

messageText is the diagnostic message text string, which comes from the SQL_DIAG_MESSAGE_TEXT field.

For more information, please see the SQLGetDiagRec function in the MS ODBC API Reference at http://msdn.microsoft.com/en-us/library/ms716256(VS.85).aspx.

SQL_SUCCESS, SQL_SUCCESS_WITH_INFO, SQL_ERROR, or SQL_INVALID_HANDLE.

The following method is called after the result from calling ODBC_SQLExecute is not equal to SQL_SUCCESS. The debugMessage variable will contain the error message:

 If($result#SQL_SUCCESS)
    $resultDiag:=ODBC_SQLGetDiagRec(SQL_HANDLE_STMT;$statementID;1;SQLState;nativeError;
    debugMessage;vTextLen)
 End if
