iccube：如何计算mdx中where子句的成员数？

Question

使用以下mdx，如果我使用或不使用where子句运行它，结果是相同的：它返回层次结构中的总年数。

with member nbYears as [Time].[Year].[Year].count
select nbYears on 0
from [Sales]
where [Time].[2007]

Answer 1

您可以使用Existing MDX功能

WITH 
   member nbYears as (Existing [Time].[Year].[Year]).count
SELECT nbYears on 0
FROM [Sales]
WHERE [Time].[2007]
