IN运算符(MySQL)的逗号分隔参数

问题描述

我有一个可以在其中执行以下查询的表:

I have a table in which the following query works fine:

select *
from session_actions
where action_type IN ('login_failed','channel_recorded')

现在，我很期待以下内容:

Now I'm looking forward to some thing like the following:

select *
from session_actions
where action_type IN ('login_failed,channel_recorded')

如您所见，我想给IN运算符一个逗号分隔的参数，但这是不可能的

As you see I want to give the IN operator one single comma separated parameter, but it is not possible

如何将该逗号分隔的字符串转换为IN运算符可接受的参数列表?

How can I convert this comma separated string into a list of parameters which is acceptable to IN operator?

推荐答案

您可能正在寻找 FIND_IN_SET() 函数.

You might be looking for FIND_IN_SET() function.

select *
from session_actions
where find_in_set(`action_type`,'login_failed,channel_recorded');
