Distinct (MDX)
Evaluates a specified set, removes duplicate tuples from the set, and returns the resulting set.
The following example query shows how to use the Distinct function with a named set, as well as how to use it with the Count function to find the number of distinct tuples in a set:
WITH SET MySet AS
{[Customer].[Customer Geography].[Country].&[Australia],[Customer].[Customer Geography].[Country].&[Australia],
[Customer].[Customer Geography].[Country].&[Canada],[Customer].[Customer Geography].[Country].&[France],
[Customer].[Customer Geography].[Country].&[United Kingdom],[Customer].[Customer Geography].[Country].&[United Kingdom]}
MEMBER MEASURES.SETCOUNT AS
COUNT(MySet)
MEMBER MEASURES.SETDISTINCTCOUNT AS
COUNT(DISTINCT(MySet))
SELECT {MEASURES.SETCOUNT, MEASURES.SETDISTINCTCOUNT} ON 0,
DISTINCT(MySet) ON 1
FROM [Adventure Works]
