MySQL SELECT一个表中的多行，使用WHERE语句在不同表上求和

Question

I'm trying to figure out how create a MySQL SELECT statement that will select users from one table, get the SUM of their payments in another table for each user, and set a conditional statement on that SUM . Something like this:

SELECT member_id
FROM users_table
WHERE SUM(payments) FROM payments_table > 100;

Any help would be greatly appreciated.

Answer 1

something like

select member_id from payments_table 
group by member_id 
having sum(payments) > 100 

or

select u.member_id, u.name 
from payments_table p 
join users_table u
on p.member_id = u.member_id
group by u.member_id, u.name 
having sum(p.payments) > 100
