SELECT first, last, username || '@' || dom.domain as emailaddress
FROM cust_main cm
LEFT OUTER JOIN cust_pkg cp ON ( cm.custnum = cp.custnum )
LEFT OUTER JOIN cust_svc cs ON ( cp.pkgnum = cs.pkgnum )
LEFT OUTER JOIN svc_email em ON ( cs.svcnum = em.svcnum )
LEFT OUTER JOIN svc_domain dom ON ( em.domain = dom.svcnum )
WHERE zip = '99999'
AND username || '@' || dom.domain != '@'
Which worked until I added one more table with a one-to-one relation to
cust_main.custnum. Then I got several tuples (2+) for each row above.
