try {
stmt = conn.createStatement();
rs = stmt.executeQuery("select count(*) from customer");
System.out.println(rs.next());
System.out.println(rs.getInt(1));
} catch (SQLException e) {
System.err.println(e.getMessage());
} finally {
System.out.println("close start");
if (rs != null) rs.close();
System.out.println("rs close end");
