使用两个 with 子句创建 table

Question

我想创建 table 并使用两个，这是我的代码：

Create Table profitTry
As
With ctsWithSplit as (select c.Tdate, c.Symbol, c.close * coalesce(s.post/s.pre, 1) as new_close
 from ctsTry c left join splits s 
on c.Tdate = s.Tdate and c.symbol = s.symbol),

delta as
( select a.Tdate as TDate,  a.Symbol as Symbol, a.price-b.price as Pdelta, b.price as oldPrice
   from ctsWithSplit a, ctsWithSplit b
   where a.TDate-b.TDate=1 and a.Symbol=b.Symbol)

select  a.TDate,a.Symbol, (a.delta-coalesce(b.dividend,0))/delta.oldPrice as percentage
From delta a left join dividend b
On a.Tdate=b.Tdate and a.Symbol=b.Symbol

"table not existed" 出现错误，请问是因为我的第 2 个 with 子句吗？

Answer 1

一个明显的问题是你的外层 select:

select  a.TDate,a.Symbol, (a.delta-coalesce(b.dividend,0))/delta.oldPrice as percentage
-----------------------------------------------------------^
From delta a left join dividend b
On a.Tdate=b.Tdate and a.Symbol=b.Symbol

没有delta。你是说 a.
