在 MDX WITH 子句中过滤层次结构

Question

通过使用MDX on multiple hierarchical dimensions 的答案，我有以下 MDX 查询：

with
member L1Y1 as ([Dim Location].[Hierarchy].[Center].&[1],
        [Dim Date].[Calendar Date].[Year].&[2010],
        [Measures].[x])                 
select ([Dim Attribute].[Parent Code].&[10000]) on 0, 
       ({L1Y1}) on 1
from DS

现在的问题是如何根据其子级过滤 L1Y1。例如，假设我们想要过滤它，以便查询中只包含第 2 季和第 7 个月。以下查询输出同上，where子句无效：

with
member L1Y1 as ([Dim Location].[Hierarchy].[Center].&[1],
        [Dim Date].[Calendar Date].[Year].&[2010],
        [Measures].[x])                 
select ([Dim Attribute].[Parent Code].&[10000]) on 0, 
       ({L1Y1}) on 1
from DS
where [Dim Date].[Calendar Date].[Season].&[2] and 
      [Dim Date].[Calendar Date].[Month].&[7]

Answer 1

除非您删除了属性，否则您的时间维度中应该有多个可用的层次结构。你可以试试这个：

with
member L1Y1 as ([Dim Location].[Hierarchy].[Center].&[1],
    [Dim Date].[Calendar Date].[Year].&[2010],
    [Measures].[x])                 
select ([Dim Attribute].[Parent Code].&[10000]) on 0, 
   ({L1Y1}) on 1
from DS
where [Dim Date].[Season].&[2] and [Dim Date].[Month].&[7]

注意，由于我们不使用层次结构[日历日期]时间成员不会被覆盖而是被过滤。

Answer 2

怎么样：

with
member L1Y1 as ([Dim Location].[Hierarchy].[Center].&[1],
        [Dim Date].[Calendar Date].[Year].&[2010],
        [Measures].[x])
member S2 as ([Dim Location].[Hierarchy].[Center].&[1],
        [Dim Date].[Calendar Date].[Season].&[2],
        [Measures].[x])
member M7 as ([Dim Location].[Hierarchy].[Center].&[1],
        [Dim Date].[Calendar Date].[Month].&[7],
        [Measures].[x])     
select ([Dim Attribute].[Parent Code].&[10000]) on 0, 
       (L1Y1, S2, M7) on 1
from DS

我知道这是一种更费力的方法，但您会得到结果。如果您只想获得单个值，则可以尝试仅保留 M7 度量。
