如何通过SQL找出2个表里值不同的列的方法_MySQL

以下有两个表，他们的结构完全相同，请通过SQL找出值不同的列。

Student_1

Student_2

方法一 -- NOT EXISTS：


SELECT *
FROM Student_1 S1
WHERE NOT EXISTS
(SELECT *
FROM Student_2 S2
WHERE S1.name = S2.name
AND S1.age = S2.age
AND S1.score = S2.score
)
UNION ALL
SELECT *
FROM STUDENT_2 S2
WHERE NOT EXISTS
(SELECT *
FROM STUDENT_1 S1
WHERE S1.name = S2.name
AND S1.age = S2.age
AND S1.score = S2.score
);

方法二 -- MINUS

(SELECT * FROM Student_1
MINUS
SELECT * FROM Student_2)
UNION ALL
(SELECT * FROM Student_2
MINUS
SELECT * FROM Student_1)

方法三 -- HAVING GROUP BY

SELECT DISTINCT name, age, score FROM (
SELECT * FROM Student_1
UNION ALL
SELECT * FROM Student_2
)GROUP BY name, age, score HAVING COUNT(*)=1 ;
