There are three tables Users, Lists, Details. Here it is my table structure and data sample
userid username | list_id list_val user_id | detail_id list_id multipler
1 user1 | 1 500 1 | 1 1 3
2 user2 | 2 300 1 | 2 1 2
3 user3 | 3 600 1 | 3 2 1
4 100 2 4 2 1
5 3 4
SELECT
users.username,
SUM(lists.lists_var),
FROM
users
INNER JOIN lists ON users.userid = lists.user_id
GROUP BY
users.username
HAVING
(SELECT (exp(sum(log(COALESCE(details.multipler, 1))))) FROM details WHERE
details.list_id = lists.list_id) > 3
This query gives me result
user1 - 1400
But I want something IF multipler_total > 3 THEN SUM(list_val) so result must be:
user1 - 1100
try this:
SELECT
users.username,
SUM(lists.lists_var),
FROM
users
INNER JOIN lists ON users.userid = lists.user_id
INNER JOIN (SELECT list_id, SUM(multiplier) mult_total FROM details GROUP BY list_id) d
ON d.list_id = lists.list_id and d.mult_total > 3
GROUP BY
users.username
