在WHERE子句中使用AND和OR进行MySQL查询

Question

I am creating a student records search query. The school has three clubs (maths, english and science). What i want to do is to select student by the club they have joined in this order. Student who are in -- Maths Only -- Maths and English only -- Maths and Science Only -- English Only -- English and Science Only -- Science Only

Student table (studentTB)

id | student_name | date_join
-----------------------------
 1 | Daniel Addo  | 2012-01-05
 2 |David Polles  | 2013-05-11
 3 | Grace Amorno | ---------
 4 | Zein Akill   | ---------

Club table (studentCLUB)

id | studentID | club
----------------------
1  | 1         | maths
2  | 1         | science
3  | 2         | science
4  | 2         | english
5  | 3         | science
6  | 4         | maths
7  | 4         | science
8  | 4         | english


SELECT *
    FROM studentTB
    INNER JOIN studentCLUB
    ON studentTB.id = studentCLUB.studentID
    WHERE (club = 'maths') OR (club = 'science') OR (day = 'english')
    GROUP BY studentTB.id

This is what i have so far and it is selecting student when they fall within one of the club. But when i change the OR to AND it gives me null. I will be glad if anyone can help me. Thank you

Answer 1

So it you need to find students who belongs to all the given club you can do as below. It will check the students having all the given 3 clubs.

SELECT *
FROM studentTB
INNER JOIN studentCLUB
ON studentTB.id = studentCLUB.studentID
WHERE
club in ('maths','science','english') 
GROUP BY studentTB.id
having count(*) = 3 

Answer 2

SELECT * FROM studentTB
WHERE EXISTS(SELECT * FROM studentCLUB
WHERE studentTB.id = studentCLUB.studentID)
