Search on raw field

Can I search on raw field? If so, what is the correct statement. I tried the following statements and none of them returns any rows. It should return some rows.

The field ID is defined as raw(255)

select ID from tableA where rawtohex(ID) > 1 select ID from tableA where rawtohex(ID) > rawtohex(1) select ID from tableA where ID > Hextoraw(1)

Thank you,
