每个订单的最新状态以及何时设置为该值

Question

我正在尝试查找每个订单的最新状态以及设置为该值的时间。我尝试了下面的查询，但结果是 this。我只是希望它显示最新状态而不是全部。太感谢了！

select order_id, updated_at, order_status
from (select order_id, 
        updated_at, 
        order_status,
        row_number() over(partition by order_id, order_status order by updated_at desc)
          as rn
     from fishtownanalytics.order_status_history) as x
where rn = 1

Answer 1

只需从分区中删除状态即可

select order_id, updated_at, order_status
from (select order_id, 
        updated_at, 
        order_status,
        row_number() over(partition by order_id  order by updated_at desc)
          as rn
     from fishtownanalytics.order_status_history) as x
where rn = 1

每个订单的最新状态以及何时设置为该值

Most recent status for each order and when was it set to that value
