I’ve adapted a report to create this query to see which users have posted the most X months ago & how many users in total have posted within that time period.
-- [params]
-- int :months_ago = 1
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
)
SELECT
ua.user_id,
count(1) AS post_count
FROM user_actions ua
INNER JOIN query_period qp
ON ua.created_at >= qp.period_start
AND ua.created_at <= qp.period_end
INNER JOIN users u
ON u.id = ua.user_id
AND u.admin = 'f'
AND u.moderator = 'f'
GROUP BY ua.user_id
ORDER BY post_count DESC
But I’m struggling to get the latter - the total number of users who posted within the time period. I think I just need a count of the number of users who’re included in the report. I’d be grateful if anyone has some pointers.
Edit - Scrap that, I can see that I can just get this from the total number of results -
