PHP MySQL返回除法结果

我有疑问：

SELECT * FROM members ORDER BY ( firstColumn / anotherColumn ) DESC

现在我打印这个：

return $query['firstColumn'] / $query['anotherColumn'];

---

是否可以在不使用任何php技巧的情况下打印分割结果？例如

return$query['dividedColumns']
列别名将解决您的问题，您可以将查询更改为：

SELECT members.*, 
      ( firstColumn / anotherColumn ) AS `divided_amount`  
FROM members 
ORDER BY divived_amount DESC;

列别名将解决您的问题，您可以将查询更改为：

SELECT members.*, 
      ( firstColumn / anotherColumn ) AS `divided_amount`  
FROM members 
ORDER BY divived_amount DESC;

您可以直接在查询中执行此操作，并将该结果用作
orderby
参数

SELECT *, firstColumn/anotherColumn as dividedColumns 
FROM members 
ORDER BY dividedColumns DESC

现在您可以在PHP中将其用作
$query['dividedColumns']

你可以试试这个

SELECT *, (firstColumn/anotherColumn) AS dividedColumns FROM members ORDER BY ( firstColumn / anotherColumn ) DESC
