Hi all.
I have a table with members and a table with payments. Each payment is
related to a member by memberID and each payment has (among other things) a
year paid.
I can create a join to find a list of members who have paid for a given year
(2002 in this case):
select member.memberID,member.name from member, payment where
payment.memberID = member.memberID and payment.yearPaid = 2002
I would like to be able to get a list of members who have not paid for a
given year.
I would also like to combine the two criteria, for example to generate a list
of members who have paid for 2002 but not 2003.
Thanks in advance!
--->Nathan
