MySQL ORDER BY x-y/x ASC 排序

Question

我想按此规则对 MySQL 查询进行升序排序:x-y/x

x = 价格

y = 价格 2

price 和 price2 是 MySQL 表中的列。

我有这个查询，但不幸的是它不起作用。

SELECT * 
FROM albums 
WHERE price2 > 1 
ORDER BY price - price2 / price ASC

感谢关注。

Answer 1

试试这个:

$SQLquery = "SELECT * FROM albums WHERE price2 > 1 ORDER BY (price-price2)/price ASC";

或

$SQLquery = "SELECT * FROM albums WHERE price2 > 1 ORDER BY ((price-price2)/price) ASC";
