Return Values
- SQL_SUCCESS indicates that the call succeeded.
- SQL_SUCCESS_WITH_INFO indicates some warning information is displayed.
- 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 were called. Values returned by other APIs are similar to the preceding values.
- SQL_STILL_EXECUTING indicates that the statement is being executed.
Precautions
If SQLFetch returns SQL_ERROR or SQL_SUCCESS_WITH_INFO, the application can then call SQLGetDiagRec, set HandleType and Handle to SQL_HANDLE_STMT and StatementHandle, and obtain the SQLSTATE value. The SQLSTATE value provides the detailed function calling information.
