Mysql 错误代码：1054。未知列'；喜欢'；在'；字段列表'；

我的要求是得到平均水平的喜欢

SELECT 
    COALESCE(SUM(type = 1), 0) AS likes,
    COALESCE(SUM(type = 2), 0) AS dislikes,
    count(type) as total_like,
    likes / dislikes, // Error on this line
    e_id  
FROM `e_rating` 
group by e_id 
order by e_id ASC

注意：仅使用单个查询获得平均值。

您需要填写完整的语句：

SELECT 
    COALESCE(SUM(type = 1), 0) AS likes,
    COALESCE(SUM(type = 2), 0) AS dislikes,
    count(type) as total_like,
    COALESCE(SUM(type = 1), 0) / COALESCE(SUM(type = 1), 0) AS average,
    e_id  
FROM `e_rating` 
group by e_id 
order by e_id ASC
