检查MDX中是否存在尺寸

Question

如何检查MDX状态下轴上是否存在一个尺寸？

我需要检查axis1上有多少时间单位（天，周，月......），并用它来计算度量。下面是例子，我应该怎么做，我会采取一些尺寸：

days -> [Measures].[A] = [Measures].[B]/number of members in axis 1, from only date dimension (365) 

months -> [Measures].[A] = [Measures].[B]/number of members in axis 1, from only date dimension (12) 

months, product group -> [Measures].[A] = [Measures].[B]/number of members in axis 1, from only date dimension (12) 

所以维度不同于日期维度不应该影响计算。我只需要从[日期]维度中指定成员。

一个简单的例子计算天数：

With 
Member [Measures].[Members on rows] AS 
Axis(1).Count 

Select 
Non Empty [Measures].[Members on rows] on columns, 
Non Empty [Date].[Day].[Day].Members on rows 
From [Sales] 
Where [Date].[Month].[Month].&[201701] 

但是，你得到的只是行数，你无法预知这是怎么回事用的轴。您还可以检查整个属性是否算=报告属性计数：

Count(existing [Date].[Day].[Day].Members) = Count([Date].[Day].[Day].Members) 

如果返回真，最有可能的，这意味着你不使用过滤器[日期]在[日]层次你报告。
