Question

我在下面有一个查询。但是在最后选择的两个字段中，USDVal＆amp;运行查询时，cp是无效的列名。我不明白为什么呢？

因为如果我运行下面的查询而不包括最后一行（“as source ..”），那么查询就会运行。

;with s as
(
   select cp, mktVal, date 
   from tblDaily
   where date = '2017-01-30' and id = 'SFAB'
), h as 
(
    select idMK, name, cp, wgt 
    from tblDrift 
    where date = '2017-03-30' and idSub = 'V12' and wgt <> 0
), m as
(
   select h.idMK, h.name, h.wgt * s.mktVal  as USDVal, h.cp
   from h left join s on h.cp = s.cp
)   
select idMK, name, USDVal, cp from m 
as source pivot(max(USDVal) for cp in ([BPP],[NCV])) as pvt

Answer 1

尝试将最后两行更改为以下内容：

SELECT pvt.*
FROM
(
    select idMK, name, USDVal, cp from m 
) as source 
pivot(max(USDVal) for cp in ([BPP],[NCV])) as pvt

source pivot不喜欢列名
