Be gentle as I come from an Oracle background a long time ago. I am trying to join several tables with a couple of tables having a one to many relationship. I got one query working pretty well but the issue comes about when I add one more table with a one-to-one relationship. I get a semi/pseudo Cartesian join. I'm not asking for the exact solution but a pointer to a _good_ reference on complex joins. My searching on the PostgreSQL site and Google only turn up examples of simple joins. I did forget to look at the two PostgreSQL books I have at home -- Bruce's and Practical PostgreSQL -- last night so if there are some in them a light tap with the clue-stick will suffice.
