Question

I’m stuck on a MDX query… I have a table which looks like:

Date         Client        Amount
---------------------------------
2010-01-01        1          1000
2010-01-01        2           500
2010-01-02        1          1100
       ...      ...           ...
2011-09-30        3          2000

Basically, I’d like to have a MDX equivalent of the following T-SQL:

SELECT [Year], [Month], AVG(DailyTotal)
FROM (
    SELECT [Year], [Month], [Day], SUM(Amount) as DailyTotal
    FROM Table
    GROUP BY [Year], [Month], [Day]
)
GROUP BY [Year], [Month]

I’m trying to get as result like

        Jan    ...   Sept
2010    AVG    ...    AVG
2011    AVG    ...    AVG

Thanks in advance

Answer 1

I have a query using Adventure Works:

with member [measures].[Average] as Avg({Descendants([Date].[Calendar].CurrentMember, [Date].[Calendar].[Date])*[Date].[Month of Year].CurrentMember}, [Measures].[Internet Sales Amount])
select 
{{[Date].[Month of Year].[Month of Year]}*{[Measures].[Internet Sales Amount], [measures].[Average]}} on columns,
{[Date].[Calendar].[Calendar Year]} on rows
From    [Adventure Works]    

In this query I’m using 2 hierarchies ([Date].[Calendar] and [Date].[Month of Year]). Maybe, in your case, you could need do something else if your time dimension have others hierarchies.
