Question

I have a table with column name LIST_CODE where data like this A101,A102,B101.

How can I find all the data where LIST_CODE equal A102 OR B101

I try bellow sql but it returns 0

SELECT count(*) FROM details_user WHERE list_code IN ('A102','C101')

Answer 1

If you mean that list_code can contain ‘A101, A102,B101’ in one row then

select * from details_user
where list_code like'%A102%' 
or list_code like '%B101%'

But this would be a bad database design.

if list_code can contain

A101
A102
B101

(one value per row)

Then your code is correct, and it’s just mean that you have no row with A102 or C101.
