如何正确选择然后将结果插入$ result？

$result = mysql_query("SELECT AVG(answervalue) 
                        FROM `tblanswer` 
                        WHERE questiontype = 'Methods' 
                         AND studentid = '$username' 
                         AND subjectname = '$server_subject' 
                         AND professorname = '$server_name', $connect);

$Query = "INSERT INTO tblevaluationgrade (result) VALUES ('$result')";
