SQL SUM Questions

[Mike]

I am using the follwoing SQL query:

SELECT RECID, PATNUMBER, Sum(amount) As Amount
FROM PAT_Transactions
Group By recid, patnumber
Having patnumber = 374757 AND recid = 'C'
Order By patnumber

My problem is that there are rows that have a a negative amount. I want to
add only the positive amount rows together. This query adds all the rows for
each patient number positive and negitive to give me the total.

How do I tell SQL to add only the positive row amounts together?

Thanks in advance!!

Hi Mike

Put in Where amount > 0

SELECT RECID, PATNUMBER, Sum(amount) As Amount
FROM PAT_Transactions
WHERE Amount>0
Group By recid, patnumber
Having patnumber = 374757 AND recid = 'C'
Order By patnumber
