数据仓库多维数据集 MDX查询的问题

我的MDX语句(查询每天24小时中的最大值):
with member [Dim Date Of Hour].[Date Of Hour Key].[最大值] as MAX({[Dim Date Of Hour].[Date Of Hour Key].&[0]:[Dim Date Of Hour].[Date Of Hour Key].&[23]})
select [Dim User Type].[Type Name].children on columns,
NonEmpty([Dim Date].[Full Date].children*[Dim Date Of Hour].[Date Of Hour Key].[最大值]) on rows
from [Kysd Statistics V2DB]
where [Dim User Type].[Parent User Type Key].&[2]
查询结果:

我想把[Dim Date Of Hour].[Date Of Hour Key].[最大值] 中的'最大值'换成MAX函数里具体的小时数该怎么写??

Answer 1

再用笛卡儿积乘下试试，你的计算度量 [Dim Date Of Hour].[Date Of Hour Key].[最大值] 本身是一个计算结果，最大值是不能换的，只能考虑通过其他写法实现。

with member [Dim Date Of Hour].[Date Of Hour Key].[最大值] as MAX({[Dim Date Of Hour].[Date Of Hour Key].&[0]:[Dim Date Of Hour].[Date Of Hour Key].&[23]})
select [Dim User Type].[Type Name].children on columns,
NonEmpty([Dim Date].[Full Date].children*[Dim Date Of Hour].[Date Of Hour Key].[最大值]*[Dim Date Of Hour].[Date Of Hour Key]) on rows
from [Kysd Statistics V2DB]
where [Dim User Type].[Parent User Type Key].&[2]
