Given the code fragment:

9. Connection conn = DriveManager.getConnection(dbURL, userName, passWord);
10. String query = “SELECT id FROM Employee”;
11. try (Statement stmt = conn.createStatement()) {
12. ResultSet rs = stmt.executeQuery(query);
13. stmt.executeQuery(“SELECT id FROM Customer”);
14. while (rs.next()) {
15. //process the results
16. System.out.println(“Employee ID: “+ rs.getInt(“id”));
17. }
18. } catch (Exception e) {
19. System.out.println (“Error”);
