    String user = "myuser";
    String password = "mypassword";

    try (Connection conn = DriverManager.getConnection(url, user, password)) {
      // Check the database version
      DatabaseMetaData meta = conn.getMetaData();
      System.out.println("Driver name: " + meta.getDriverName());
      System.out.println("Driver version: " + meta.getDriverVersion());
      System.out.println("Product name: " + meta.getDatabaseProductName());
      System.out.println("Product version: " + meta.getDatabaseProductVersion());
    } catch (SQLException e) {
      System.err.println("Error: " + e.getMessage());
