I have a where condition in my query checking long column

where long_type IN (4,5)

m creating "str = (4,5)" in my code and setting to positional parameter using

q.setString(0,str);

but the query fails ,it says

Invalid character string format for type INTEGER.

Any clue how to make it work?

Thanks in advance
