I have a table called ratings
, and a column called item_id
. I simply would like to group each individual item together and count them.
For example:
if there are 1000 rows, and item_id
51 has been rated 20 times, and item_id
14 has been rated 7 times and item_id
33 has been rated 2 times, I simply want it to be grouped in DESC
like:
item_id 51 item_id 7 item_id 33
I tried to follow something like this question , but could not get it to work.
SELECT item_id, COUNT(*) AS count
FROM ratings
GROUP BY item_id
ORDER BY count DESC;
SELECT count(*) AS counter, item_id
FROM ratings
GROUP BY item_id
ORDER BY counter DESC
SELECT *
FROM (
SELECT item_id, COUNT(rating) AS rating
FROM ratings GROUP BY item_id
) a
GROUP BY a.rating DESC
