You will need to shorten the memo
field to be able to use it in this manner. Try:
CAST(Desc AS NVARCHAR(2000))
Question
I'm working on a crystal report and I want to insert a pie chart that shows percentages. I have a view that contains the field that I'm interested in : Descr(descrtiption) (NVARCHAR), I successfully added a command that gets the number of occurences of each Description. The problem is that when I try to add that field to the chart I can't see it,
here is the query that gets the values
here is the chart expert window I get
and as you can see the field is not checked in the field explorer

OTHER TIPS
Use Having clause instead of where condition in query.
Select count(*) as NBoccurrence,descr
From tbl_nm
Group by descr
Having your condition
