php - Multiplication within SQL statements?

Question

$query = mysql_query('SELECT * FROM submissions ORDER BY (votes * id) DESC');

This gives me an error. Is there any way to do this?

Answer 1

我邀请您按投票数和 ID 获取提交顺序列表。
你可以使用这样的代码：

$query = mysql_query('SELECT * FROM submissions ORDER BY votes DESC, id DESC');

Answer 2

SELECT *, (votes * id) AS x FROM submissions ORDER BY x DESC

你会多写一列，但我想我会工作=|

Answer 3

只要类型正确，您提供的 SQL 就有效。至少在 Postgres 中。你用的是什么数据库？
