Find value in comma delimited string mysql

Question

I have a table in my DB that looks like so:

member_id    name    mgroup_others    member_group_id
    1        Name1      2,3,10              1
    2                 


        

Answer 1

SELECT * FROM table WHERE FIND_IN_SET(10,mgoup_others)>0

This is a temp solution,in a production db this will be slower than a turbo snail.

Answer 2

Use LIKE

SELECT * 
FROM yourtable 
WHERE mgroup_others LIKE '%10%'

Answer 3

Since mgroup_others is a varchar column what if you simply use LIKE operator other than FIND_IN_SET() like

select * from table1
where mgroup_others like '%10'

You can as well use FIND_IN_SET() like below

select * from table1
where find_in_set(10,mgroup_others)
