Perhaps you need to tell us what your problem is instead of your
solution. What exactly are you trying to accomplish here? Don't
describe it in database terms. Tell us what the real world situation
is and what result you want to see. For example;
I have a list of people related to each other in a parent/child
relationship to any level (e.g. parents, grandparents, etc.) and I want
to list everyone who is a descendant of anyone in the database.
Try for that level of detail and you will probably get more useful
answers. Also, see http://www.catb.org/~esr/faqs/smart-questions.html
for some useful hints on asking questions.
