Question

我正在尝试查找每个订单的最新状态以及将其设置为该值时的状态。我在下面尝试了查询，但是发生了this。我只希望它显示最新状态，而不是全部显示。非常感谢！

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，它将起作用

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
