Question

我有以下查询

SELECT * FROM table WHERE id IN (5,4,3,1,6)

我想再次从SELECT中获得该值“ 5,4,3,1,6”。

SELECT * FROM table WHERE id IN (SELECT popuplarList FROM Settinng WHERE id =1 )

但是我只得到5号帖子。我想从“ 5,4,3,1,6”中获取所有帖子。

是否可以通过其他逻辑或其他方式解决此问题？

非常感谢

Answer 1

尝试FIND_IN_SET方法

SELECT * FROM table WHERE FIND_IN_SET(id, (SELECT popuplarList FROM Settinng WHERE id =1 ))

Answer 2

请尝试以下操作：

第一个解决方案：

    select * 
    from table 
    where (
        select CONCAT(",", popuplarList, ",")
        from Settinng where id = 1
    ) like concat("%,", id, ",%")

第二种解决方案：

    select * from table WHERE FIND_IN_SET(`id`, (
       select CONCAT(",", popuplarList, ",") from Settinng where id = 1)
    )

MySQL-SELECT…WHERE ID IN（SELECT ...）
