            ResultSet rs = st.executeQuery(sql);
            ResultSetMetaData rmeta = rs.getMetaData();
            int numColumns = rmeta.getColumnCount();  
            while ( rs.next() ) {
                for (int i = 0; i < numColumns; i++) {
                    System.out.println(rs.getString(i));
                }
                System.out.println();
            }


        } catch(SQLException sqe) {
