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
