something like this

Now when

Answer 1

For most versions of SQL, you need to escape the single quote, for example.

select * from emp where empname like ('john,1,devil''s,corn')

Also, the above example is looking for a very specific string value, you need to include * or ? as wildcard characters, so to look for all empname's like devil's, use

select * from emp where empname like '%devil''s%'

Another example

select * from emp where empname like 'john,1%'
