is is possible to order by multiple rows?
I want my users to be sorted by last_activity, but at the same time, i want the users with pictures to appear before the ones without
Something like this:
SELECT some_cols
FROM `prefix_users`
WHERE (some conditions)
ORDER BY last_activity, pic_set DESC;
SELECT some_cols
FROM prefix_users
WHERE (some conditions)
ORDER BY pic_set DESC, last_activity;
