        return queryRunner.query(sql, new BeanListHandler<Order>(Order.class), user_id, paystate);
    }
    
    

}

3.OrderitemDaoImpl

        String sql = "delete from `order` where order_id = ?";
        queryRunner.update(sql, order_id);
    }

}

4.orderitem_insert觸發器

代碼

orderitem中每增長一項，將他對應的order_id的訂單的錢增長上他的書的價格乘以數量。

DROP TRIGGER IF EXISTS `orderitem_insert`;
DELIMITER ;;
CREATE TRIGGER `orderitem_insert` AFTER INSERT ON `orderitem` FOR EACH ROW begin
    update `order` set money = money + new.price * new.count where order_id = new.order_id;
end
;;
DELIMITER ;
