help - JOIN problem

[KeithR]

Hi all,
I have 3 tables; USER, ACCESS_PATH, and ACCESS (All of the
generation scripts are at the end). USER contains users information,
ACCESS_PATH contains a URL and an ID, and ACCESS contains USER ids and
ACCESS ids
I am basically trying to adminster my home website with access
levels. So user1 can see some stuff, and user2 can see some other
stuff, while I (admin) can see everything.
Here's my problem I'd like to have a query that does a left join on
the cartesian product of USER and ACCESS, thus showing me what users
do and do not have access to, so when a NULL value comes up for some
column ex:
'enabled', the user does not have access otherwise they do.

Any help appreciated,
Keith
