I didn't see a response for this, so here goes... I believe you can implement joins using the followng syntax: select t1.value from table_one t1, table_two t2 where t1.key = t2.key; So this would be a straight LEFT join in my understanding. Now, I'm venturing beyond my experience with PostgreSQL here, but you may be able to use the associated SQL syntaxes: select ... where t1.key *= t2.key select ... where t1.key =* t2.key etc... I hope I'm right here :) Regards, Joe.
