假设我有些武断的话 INT
-类型 ORDER_SIZE
. 我需要一个额外的专栏 FILLED
这说明 ORDER_SIZE
以及 AMOUNT
使得 FILLED
等于 ORDER_SIZE
.
它将需要 PARTITION BY
-埃德 PAIR
, TIMESTAMP
,和 SIDE
.
例如,如果我的 ORDER_SIZE
是 5
,我会得到以下结果:

因此 FILLED
下到第十个最深的订单是我们的原始订单 ORDER_SIZE
(5).
我怎样才能在一个小时内完成这一点 SELECT
? 我需要它在一个表函数中返回。我实际上是在snowflake中实现的,但是假设我可以访问所有常见的sql窗口函数(例如。 LEAD
, LAG
, RANK
等)
谢谢!!
