I have a measure where the data in the column is based on currency.  The results of the stored procedure which creates this column and inserts data looks like this:

<blank>  Stored Procedure uses a CASE statement and the ELSE is NULL (is <blank> correct?)
   0.00
130.00

I want to perform a count on everything that IS NOT NULL.
How can I do this in my cube?

COUNT,  like all aggregate functions, ignores nulls


select count(your_column) from your_table

will ignore the null values in your_column
0

yes

count (and all aggregates)  operate on all non-null values.  including 0 (zero)

if you want your count to ignore zero values as well as null's then try something like this...



select count(case when your_column = 0 then null else your_column end) from your_table
