Question

我有来自同一个多维数据集的2个MDX查询。两者都使用相同的度量，但具有不同的时间集（时间集都是相同的维度但不同的层次结构）。

我希望将它们加入到相同的表结果中，因此它将呈现2个度量（由不同集合切割）和另一个时间维度（“星期几”），它们也使用相同的时间维度。查询可以单独运行，如下所示：

   with member [Measures].[AVG_6_WEEKS] as 
     [Measures].[Number of Answered Comms] /6
    select 
    nonempty([Comm Date UTC].[Day of Week].children)
    on 0, 
    [Measures].[AVG_6_WEEKS]
    on 1 
    from (select {LASTPERIODS( 42,[Comm Date UTC].[Year Month Day].lastsibling.lastchild.lastchild.lastchild.prevmember )}
    on 0 from comms)

;
 with member [Measures].[Answered Comms] as 
 [Measures].[Number of Answered Comms] 
select 
nonempty([Comm Date UTC].[Day of Week].children)
on 0, 
[Measures].[Answered Comms]
on 1 
from (select {LASTPERIODS( 7,[Comm Date UTC].[Year Month 
Day].lastsibling.lastchild.lastchild.lastchild.prevmember )}
    on 0 from comms)

可以吗？我总是得到一个错误，我不能在查询中使用相同的时间层次结构... 任何的想法？像SQL这样的东西我可以加入2个视图吗？

谢谢

以下MDX应该这样做：

with member [Measures].[AVG_6_WEEKS] as 
     Aggregate({LASTPERIODS( 42,[Comm Date UTC].[Year Month Day].lastsibling.lastchild.lastchild.lastchild.prevmember )},
               [Measures].[Number of Answered Comms] /6
              )
     member [Measures].[Answered Comms] as 
     Aggregate({LASTPERIODS( 7,[Comm Date UTC].[Year Month Day].lastsibling.lastchild.lastchild.lastchild.prevmember )},
               [Measures].[Number of Answered Comms]
              ) 
select 
nonempty([Comm Date UTC].[Day of Week].children)
on 0, 
{ [Measures].[AVG_6_WEEKS], [Measures].[Answered Comms] }
on 1 
from comms

我使用Aggregate函数将查询中的子选择的上下文移动到成员定义。

结合2个mdx查询
