sql - MySQL order results by total by weights -


i have following query:

select   p.`id`,   (select count(`id`) `comments` c c.`post_id` = p.`id`) `comments`,   (select count(`id`) `likes` l l.`post_id` = p.`id`) `likes` `posts` p

i want order results according third column, calculated following way:

order = comments * 6 + likes * 4

how can create "virtual" column , use results of other 2 in calculation?

thanks!

i rewrite query way:

select     p.id,     count(distinct comments.id) comments,     count(distinct likes.id) likes,     count(distinct comments.id)* 6 + count(distinct likes.id)* 4 `order`     posts p left join comments on p.id = comments.post_id     left join likes` on likes.`post_id` = p.`id` group     p.id order     `order`
