从mysql中选择数学并按它们排序

Question

我尝试通过选择ORDER结果。那可能吗？

SELECT *,(row1/row2/row3/row4) as order111 FROM `ad` ORDER BY `order111` ASC

Answer 1

不确定您要实现的目标，但这应该有效：

SELECT *,(row1/row2/row3/row4) as order111 
FROM `ad` 
ORDER BY (row1/row2/row3/row4) ASC

Answer 2

你试过吗？

SELECT *
     , (row1/row2/row3/row4) AS order111
FROM ad
ORDER BY order111 ASC

在MySQL中是可以接受的。
