Holds a field value. The {@code Value} methods attempt to convert the field value to Java types. @author Mike Heath


      // Make sure we can select the row
      rs = connection.executeQuery("SELECT id FROM updates").get();
      assertNotNull(rs);
      assertEquals(rs.size(), 1);
      Value value = rs.get(0).get(0);
      assertEquals(value.getInt(), 1);


      // Rollback transaction
      connection.rollback().get();


      // select query should now be empty
