How to use operator "in" with MDX in SSRS? - sql

Question

I'm building an ssrs report with this MDX query:
SELECT
NON EMPTY { ([KeyWords Dim].[Keywords].[Keyword].ALLMEMBERS *
[Ad Dim].[Countries].[Countries].ALLMEMBERS *
[Creative Dim].[Creatives].[Title].ALLMEMBERS ) } ON ROWS,
[Measures].[Clicks] ON COLUMNS
FROM [CubeName]
WHERE ([Time Dim].[Day ID].&[20140701]:[Time Dim].[Day ID].&[20140701])
I want to add another where clause to get only result for specific countries, something like that:
Where [Getways Dim].[Countries].[Countries].ALLMEMBERS IN ([Getways Dim].[Country].[Countries].&["Germany"],[Getways Dim].[Country].[Countries].&["US"]...)
How to do the "IN" part?
Thanks

In MDX, you do not use IN, you specify a set. The easiest way to specify a set is to just a list of members on braces like this:
WHERE {
[Getways Dim].[Country].[Countries].&["Germany"],
[Getways Dim].[Country].[Countries].&["US"]
}
and to combine conditions on two different hierarchies like Time and country, you build a cross product like this (* is the cross product operator in MDX):
WHERE ([Time Dim].[Day ID].&[20140701]:[Time Dim].[Day ID].&[20140701])
*
{
[Getways Dim].[Country].[Countries].&["Germany"],
[Getways Dim].[Country].[Countries].&["US"]
}
