Using DISTINCT, COUNT and HAVING in a MySQL Query

Question

I want to count all players that have a sum of at least 300 points after a given date. I have this:

SELECT
    COUNT(DISTINCT playerID)
FROM
    table
WHERE
    game_date > '$date'
HAVING
    SUM(points) >= 300

Which is counting also the players that have a sum of less than 300 points. How can I solve this?

Answer 1

As pointed out by Andre Bossard:

To get the list of all players with points>=300:

SELECT * FROM (SELECT playerID, SUM(points) points FROM table WHERE game_date>'$date' GROUP BY playerID) a WHERE points>=300

To get the count:

SELECT COUNT(*) FROM (SELECT playerID, SUM(points) points FROM table WHERE game_date>'$date' GROUP BY playerID) a WHERE points>=300

Answer 2

Use a subquery for that:

SELECT COUNT(*) FROM
(
  SELECT playerID, SUM(points) AS `total`
  FROM `table`
  WHERE game_date > '$date'
  GROUP BY playerID
) tmp
WHERE total>=300
