通過在mysql中查詢的雙重排序

Question

我想要從表中發佈8條最高評級的帖子（posts.rates）和8條最多查看的（posts.views）對同一個查詢，所以我得到16結果。這兩個字段在同一張桌子上。 所以很晚，實際上不知道該怎麼做。提前致謝。

我wan't不這樣做下面一個查詢，得到16行：

SELECT id FROM posts 
ORDER BY rates DESC 
LIMIT 0,8; 


SELECT id FROM posts 
ORDER BY views DESC 
LIMIT 0,8; 

編輯：答：

SELECT id FROM (SELECT id FROM posts ORDER BY views DESC LIMIT 0,8) AS a 
UNION ALL 
SELECT id FROM (SELECT id FROM posts ORDER BY rates DESC LIMIT 0,8) AS b 

Answer 1

嘗試UNION

(SELECT id FROM posts ORDER BY rates DESC LIMIT 0,8) 
UNION ALL 
(SELECT id FROM posts ORDER BY views DESC LIMIT 0,8)
