Current:
Select  Company_Id ci, count (distinct Order_Number) cnt
From TableA
Having  Count(Order_Number) >1

Order Number is a alpha numeric, example PQR0725102115, and is nvarchar.

Yields:

Ci            cnt
1               10
2                 2
3                 6
4               15

Desired result:

I need the sum of the cnt column:

cnt
33

The problem is in the nvarchar.

Don't think the problem really is the nvarchar. You're definitely on the right track, but simply may need to sum what you just queried.

Try this:

Select  ci,
        SUM(cnt) AS cntSum
From  ( Select  Company_Id AS ci,
                count (distinct Order_Number) AS cnt
        From    TableA
        Having  Count(Order_Number) >1 ) t1
Group By ci

I added the "AS" simply for readability.

Hey dsacker thanks for the help.

After implementing your solution I still get

Ci            cnt
1               10
2                 2
3                 6
4               15

I need just one row sum result on cnt:

cnt
33
0

This should work. :)

Select  SUM(cnt) AS cntSum
From  ( Select  Company_Id AS ci,
                count (distinct Order_Number) AS cnt
        From    TableA
        Having  Count(Order_Number) >1 ) t1
