Re: Recursive use

I think it is not administration thing, but SQL language problem.
PostgreSQL is SQL92 compatible and has many very good and useful addons.
Generally, PostgreSQL gives You tools to analyze all, what You want,
when You hava data in tables.
You've explained in to short way You problem. The best is for example,
to give example project of tables, relations and their contents. Without
this I must build taht's all personally.
I suppose, You have to use construction:
select .... from (select ...) as foo;
or You can use views
or use cursor - first learn a little bit PLPGSQL language - it's very
simple and it is the best way; You can build with PLPGSQL the function,
what can return the result for You.
All about PosgreSQL SQL implementation and PGPLSQL You can find in
PostgreSQL doc's. I think it is very good written.
