如何通過SQL找出2個表裡值不同的列的方法

以下有兩個表，他們的結構完全相同，請通過SQL找出值不同的列。

Student_1

NAME	AGE	SCORE
peter	26	100
jack	25	96
daniel	26	48
bark	21	69

Student_2

NAME	AGE	SCORE
peter	26	89
jack	25	96
daniel	26	48
bark	21	69

方法一 -- NOT EXISTS：

複製代碼 代碼如下: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

複製代碼 代碼如下:(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

複製代碼 代碼如下:SELECT DISTINCT name, age, score FROM (
SELECT * FROM Student_1
UNION ALL
SELECT * FROM Student_2
)GROUP BY name, age, score HAVING COUNT(*)=1 ;
