用mysql中的數學公式排序

Question

我想在最流行的索引頁面上顯示用戶的帖子。

而且我有（喜歡+意見，不喜歡）/（今天的日期，posteddate）計算它

我可以通過數學公式ORDER BY子句中的MySQL？

編輯：

確定這裏是我使用的是現在查詢：

SELECT Posts.PostId, Posts.PostTitle, Posts.TextContent,Posts.PostType, PostedAs, CONCAT(PostedDate,' ',PostedTime) AS Date, 
COUNT(PostLikes.PostId) AS Likes, COUNT(PostViews.PostId) AS Views, 

(CASE Posts.PostType 
WHEN 'media' 
THEN (SELECT MediaContent FROM PostsMedia WHERE PostsMedia.PostId = Posts.PostId GROUP BY PostsMedia.PostId) 
ELSE 
'non-media' 
END 
) AS MediaContent, 

(CASE Posts.PostType 
WHEN 'media' 
THEN (SELECT MediaType FROM PostsMedia WHERE PostsMedia.PostId = Posts.PostId GROUP BY PostsMedia.PostId) 
ELSE 
'non-media' 
END 
) AS MediaType 
FROM Posts, PostLikes, PostViews 
WHERE Posts.PostId = PostLikes.PostId AND PostLikes.Liked = 1 AND Posts.Classification <> 'sales_related' AND (LOWER(Posts.PostType) != 'text' AND LOWER(Posts.PostType) != 'shout') 
AND Posts.Filter<>'HOME' GROUP BY PostLikes.PostId, PostViews.PostId ORDER BY Likes DESC, Views DESC $limitClause 

Answer 1

是。您沒有提供任何實際的代碼，但它近似：

SELECT (likes+views-dislikes)/(today's date-posteddate) AS popularity 
FROM thetable 
ORDER BY popularity DESC 

或

SELECT item1, item2 
FROM thetable 
ORDER BY (likes+views-dislikes)/(today's date-posteddate) DESC
