So here we have transaction date also....what if in 1st transaction only he has made transction greater than limit
84 days to go
which software are you using.. i am using mysql software i cant update the tables from your github its show some error
its postgres. You need to change the syntax as er mysql
SELECT u.user_id, u.user_name, u.credit_limit, SUM(t.amount) AS total_spent
FROM users u
JOIN trans t ON u.user_id = t.paid_by
GROUP BY u.user_id, u.user_name, u.credit_limit
HAVING SUM(t.amount) > u.credit_limit;
Is it right ?
