Question

I am trying to create an payment report which lists the sum in each account.
The table is in SQL SERVER 2005 and it has the following table

[Account]    [Amount]   [Type]

1111     10     C

1111     10     C

1111     15     D

1111     5     D

1112     10     C

1112     15     C

1112     10     D

1112     10     D

I need to create report that will sum the Credit and Debit for each account
Output

1111    0

1112    5

Is there a single SELECT statement that I can use to generate the output? I can do this by creating temp tables but I was wondering if I can do it in a single SELECT statement

Answer 1

select Account, 
    sum(case when Type='D' then Amount * -1 else Amount end) as AmountSum
from Payment
group by Account
