        Creates the SQL for this query. Returns the SQL string and list
        of parameters.  This is overridden from the original Query class
        to handle the additional SQL Oracle requires to emulate LIMIT
        and OFFSET.

        If 'with_limits' is False, any limit/offset information is not
        included in the query.
