Suppose we have store data like 1,2,3,4
and find with single record like 1
than we can use select query
select * from table where id=1 .
when run query your result set return 0 but if you can use select query with FIND_IN_SET than you will get result. like this query
select * from table where FIND_IN_SET(‘1’,id) // here id is field name.
Hope you help..cheers!.
