Topics solved by regular users

(There is probably a way to combine this query with the staff query.)

The number of topics solved by staff for a given time period, broken down by categories. The categories array can be altered by editing this line: WHERE t.category_id = ANY ('{46,25,43,40,44,35,22,7,20,17,6,12}'::int[]). It is possible to alter the query so that it returns results for all categories, or so that the categories array is supplied as a string parameter in the form {1, 2, 3}.

-- 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
t.category_id,
COUNT(1) AS solved_count
FROM user_actions ua
JOIN topics t
ON t.id = ua.target_topic_id
