Question

My query:

SELECT *
FROM ranks
WHERE
    (price = 25.00 AND accumulate = 0)
    OR
    (price <= (SELECT SUM(amount) FROM donations WHERE username = 'username' AND amount IN (SELECT price FROM ranks WHERE accumulate = 1)))
ORDER BY price
DESC LIMIT 1

Basically I want to return the first where clause if it finds a match, otherwise return the second clause.

Answer 1

This query will work

SELECT *
FROM ranks
WHERE price = 25.00 AND accumulate = 0

UNION ALL

SELECT *
FROM ranks
WHERE NOT EXISTS(SELECT *
                  FROM ranks
                  WHERE price = 25.00 AND accumulate = 0)
      AND (price <= (SELECT SUM(amount) FROM donations WHERE username = 'username' AND        amount IN (SELECT price FROM ranks WHERE accumulate = 1)))
ORDER BY price
DESC LIMIT 1
