如何使用mysql获得总订单价格？

Question

有两个表，一个是订单，第二个是order_details，

order 表

order_id    order_name
1           shoes
2           wallet
3           socks
4           bats

order_details 表

order_details_no  order_id(foregin key)  order_price
        1              1                   25
        2              1                   55
        3              2                   65
        4              4                   30
        5              4                   60

我的问题是，我想要的结果集包括order_id，订单总价格按升序排列（例如，订单总数为80，订单总数为90）

如何获得这个？

Answer 1

select order_id, 
       sum(order_price) as total_sum
from order_details
group by order_id
order by total_sum asc

Answer 2

Select 
    order.order_name, 
    sum(order_details.order_price) as price 
from order 
     join order_details 
       on order_details.order_id=order.order_id 
group by 
    order.order_id 
order by 
    price desc
