Hi Stephane
I am asking this simply because I was thinking if Oracle is capable to eliminate join from 11gR1 why it cannot eliminate redundant outer joins. That's all. I am not meaning we should not use outer join nor write proper queries. I simply wanted to prove that my thinking about outerjoin+fk+not null, if all 3 conditions are met outer join is not needed
