Hi, I decide to open new topic for this:
Top quality users in last six months
Well, for the Top quality users in last six months, I used the 2nd version from query.
And I added the username; and a :limit param.
-- [params]
-- int :limit = 20
SELECT
sum(p.score) / count(p) as "average score per post",
count(p.id) as post_count,
-- p.user_id,
u.username
FROM posts p
JOIN users u ON u.id = p.user_id
WHERE p.created_at >= CURRENT_DATE - INTERVAL '6 month'
AND NOT u.admin
AND u.active
GROUP by user_id, u.views, u.username
HAVING count(p.id) > 50
ORDER BY sum(p.score) / count(p) DESC
LIMIT :limit
Top 50 posters
For the “Top 50 posters”'s query, I used this version, and I added param for limit, and the username you need.
-- [params]
-- int :months_ago = 1
-- int :limit = 50
WITH query_period AS (
SELECT
date_trunc('month', CURRENT_DATE) - INTERVAL ':months_ago months' as period_start,
date_trunc('month', CURRENT_DATE) - INTERVAL ':months_ago months' + INTERVAL '1 month' - INTERVAL '1 second' as period_end
),
user_posts_in_period AS (
SELECT
p.user_id, u.username
FROM users u, posts p
INNER JOIN query_period qp
ON p.created_at >= qp.period_start
AND p.created_at <= qp.period_end
WHERE p.user_id > 0
AND u.id = p.user_id
)
SELECT
up.username,
-- up.user_id,
count(1) as post_count
FROM user_posts_in_period up
GROUP BY up.user_id, up.username
ORDER BY post_count DESC
LIMIT :limit
Let me know if it works as you want.
Regards
