I had a suspicion that JOIN was going to be part of the answer. I guess I had not found documentation that really helped. I have been searching for more information. I found this: 11.2. Controlling the Planner with Explicit JOINs I guess I am just slow.... It mentions 'inner joins', outer joins, left joins. .... I get lost. Where can I get more info. I really want to understand. Thanks for your time. I guess it's back to the bookstore. -----Original Message----- From: "Joseph Syjuco" <joseph@asti.dost.gov.ph> To: "postgresql" <pgsql@symcom.com> Date: Fri, 7 Sep 2001 08:50:20 +0800 Subject: RE: [SQL] > select i.cname from fc_client_info i inner join fc_communication c on i.acode=c.acode where c.contactdate='090601' order by cname > > -----Original Message----- > From: pgsql-sql-owner@postgresql.org > [mailto:pgsql-sql-owner@postgresql.org]On Behalf Of postgresql > Sent: Friday, September 07, 2001 1:12 AM > To: PgSQL-SQL > Subject: [SQL] > > > I am basically self taught with sql.
