6. A simple stored procedure is successful. This is just a demonstration. The stored procedure can execute multiple SQL statements at a time. Therefore, the php tutorial can query multiple statements only once when connected to the database; however, to return multiple result sets, you must use the mysqli extension for query. Otherwise, the error can't return a result set in the given context will be prompted.
