as a relatively unsophisticated dbms user (just dynamic web site back
end),
i thought it was very interesting to see the kinds of things oracle users
do
that i'd never have imagined.
more than 61 joins in a query?! man, those guys are hardcore.
Hardcore stupid if you ask me. I suppose it is "possible" to have a valid
reason (can't imagine what it might be) for using more than 61 joins. But
I would be willing to bet that 99.99% of the time if you get even close to
that many joins you have a very poorly designed database. I would also
bet that 80% of the people who are actually writing queries with that many
joins don't have a solid grasp of the fundamental principles of relational
database design.
Why not? Normalizing gets you -more- tables, not less.
That being said, try joining several complex views and you'll get more
joins...
