comma separated argument for IN operator, MySQL

Question

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

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


        

Answer 1

You might be looking for FIND_IN_SET() function.

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

Answer 2

I tried FIND_IN_SET but it was super slow. I rather use haystack REGEXP CONCAT('[[:<:]]', needle, '[[:>:]]') since then.
