Subject: [SQL] two sums in one query
hi
i have a table like this:
serialno varchar,
debit integer,
credit integer,
amount numeric
the columns 'debit' and 'credit' refer to the acount number. I want to
query the table to select all the rows where either debit = account
or credit=account and to get two sums - one of the amounts where the
account is on the debit side and the other on the credit side. Can i
do this in one query? if so, how?
