Subject: SELECT question.
I am stuck on a select query and was wondering if someone could help.
I
have I've written a database app. that helps me run my business
(trucking). I need however to write a query that shows me all of the
loads that are delivered but not billed (invoiced). Which means that I
have to select the loads that are delivered but do not have an entry in
the INVOICED table -- since an entry is made in the INVOICED table
whenever a load is billed.
I know the query below won't work. Can someone please help me fix it?
SELECT l.load_no l.date FROM loads l, invoiced i
WHERE l.dlvr_date > 0
AND l.load_no != i.load_no
Thanks,
Richard
