统计子查询的结果并在查询中使用

Question

我有两个表 information_business 和 business_likes。

Table-1 :- information_business 有字段id , name , address , dt_added 等。

Table-2 :- business_likes 有字段id , business_id , user_id , status(1=> like , 0 => unlike)

如果有人喜欢一家企业，我将在 business_likes 表中插入新数据作为 business_id、user_id 和 status = 1，并且如果同一个人不喜欢该行，则更新该行。

现在我的问题是我想选择所有点赞数最高的商家，点赞数最低的商家在最后。

如果任何企业的计数为零，则所有计数为零的企业都排在最后。

我尝试了很多查询，但对我没有任何帮助。

查询：

SELECT *, (SELECT COUNT(status)
FROM business_likes) AS business_likes_count
FROM `business_likes`
LEFT JOIN information_business ON information_business.id = business_likes.business_id
ORDER BY business_likes.id

Answer 1

试试这个 sql：如果你想把最高值放在第一位，你可以使用 group by on business id 和 ORDER BY business_likes_count DESC。

     SELECT information_business.*,COUNT(status) as business_likes_count FROM `business_likes` JOIN information_business 
ON information_business.id= business_likes.business_id group by  business_likes.business_id ORDER BY business_likes_count DESC;
