How do I sum only negative field values in MS SQL reports

Hi Xperts.

This might be an easy answer for you guys, but its a tough question for me!

I've built a simple SQL report which needs to total wirless accounts which have negative message balances on their unit's.

and then sum only the negative values in order to produce a total of the negative numbers ignoring the positive numbers.

EXAMPLE of what I need:

Record 1 Value  2
Record 2 Value -2
Record 3 Value -2

SUM of ALL records =  -4 which ignores the positive numbers

My current formula doesn't work because it 'sums' everything instead of just negative numbers.


Thank you very much for your help.

Without seeing your table structure it is a little difficult to know, but something like this should work:

Select Account, SUM(OverageRemain)
From  TableName
Where SIGN(OverageRemain)  != 1
Group By Account
=  Sum(iif(Fields!OverageRemain.Value >= 0, 0, Fields!OverageRemain.Value))
