SQLExecute

Description

If a statement contains a parameter marker, the SQLExecute function uses the current value of the parameter marker to execute a prepared SQL statement.

Prototype

1

SQLRETURN SQLExecute(SQLHSTMT    StatementHandle);

Parameters

Return Values

• SQL_SUCCESS indicates that the call succeeded.
• SQL_SUCCESS_WITH_INFO indicates that some warning information is displayed.
• SQL_NEED_DATA indicates that parameters provided before executing the SQL statement are insufficient.
• SQL_ERROR indicates major errors, such as memory allocation and connection failures.
• SQL_NO_DATA indicates that the SQL statement does not return a result set.
• SQL_INVALID_HANDLE indicates that invalid handles are called. This value may also be returned by other APIs.
• SQL_STILL_EXECUTING indicates that the statement is being executed.

Precautions

If SQLExecute returns SQL_ERROR or SQL_SUCCESS_WITH_INFO, the application can call SQLGetDiagRec, with HandleType and Handle set to SQL_HANDLE_STMT and StatementHandle, respectively, to obtain the SQLSTATE value. The SQLSTATE value provides the detailed function calling information.
