## Combine BottomCount() with Other MDX Functions to Add Sophistication - Page 2November 21, 2008 As we might have expected, this simple beginning hardly
achieves our ultimate objectives: it returns the
Descendants() function, see my article, a member
of the MDX
Member Functions: The "Family" FunctionsMDX Essentials series at Database Journal. For an
introduction to the .CurrentMember function, see , another
article in the same monthly column.MDX
Member Functions: "Relative" Member Functions3.
Select 4. Leave the query open for the next section. Next, we need to add logic to generate the same “bottom four”
data, but for an 5.
Within the
query we have saved as -- MDX072-1-2, BottomCount(), combined with Ancestor() -- and .Name in a calculated member, to provide -- U. S. States with each of "Bottom 4 Least Performing -- (with regard to Total Reseller Sales Amounts) Cities -- in Adventure Works Organization in CY 2003" 6.
Save the query
as 7.
Add the
following lines to the query, between the top comment line we just replaced,
and the WITH MEMBER [Measures].[State] AS 'ANCESTOR([Geography].[Geography].CURRENTMEMBER, [Geography].[Geography].[State-Province]).NAME' This
will create the calculated member
Ancestor() function, see my article,

Re-save the file as 12. Leave the query open for the next step. At this point, all that remains is to generate the “bottom

Substitute the

introductory article, BottomCount() function, and
then extended our examination of BottomCount() to include a somewhat
more sophisticated use. We defined an illustrative business need, as posed to us by
hypothetical groups of information consumers, and, after discussing the need in
general, with regard to challenges inherent to meeting them with the ## About the MDX Essentials Series ...This article is a member of the For more information about the column in general, as well as
