A good rule with WebObjects is "If you are thinking about SQL, you are doing it
wrong." There are times (i.e. when optimizing) when you do need to think about
the SQL, but thinking in terms of objects is usually the better way.

WebObjects (EOF) does not do mixed table selects like this (unless you are
selecting Raw Rows). It selects whole rows of tables and makes them into
related Java objects.

What are the relationships in the model between A, B, C, and D? What are you
trying to fetch?
