How can i find total of article for each user and for each status from this table.

From table:
user with id 1 , have 2 accepted article and 1 rejected article.
user with id 2 , have 1 accepted article and 0 rejected article.

If i make something like:

SELECT count(*) total FROM article_reviewers ar
INNER JOIN articles a
ON ar.article_id = a.id
GROUP BY ar.user_id

I got total article for each user, how can i find for each status?
Can someone show me light on how to do this, im quite clueless.

Answer 1

You're nearly there:

SELECT ar.user_id, a.status, count(*) total
FROM article_reviewers ar
INNER JOIN articles a
ON ar.article_id = a.id
GROUP BY ar.user_id, a.status
