Hello, I have a table which contains 5 columns the last 3 indicate wether the employer worked with given project or not. The values are simply Yes and No. What I need is a list of people who haven't worked in at least one project. So for example we have data: John Smith Yes No Yes Tim Robins No No Yes Joe Bar Yes Yes Yes Ben Finch Yes No No So the SQL statement should retrieve: Finch,Robins and Smith. -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
