I think what Michel is trying to say is that so-called "Brain dumps" are illegal and considered cheating. OraFAQ has a very strict policy in this regard: zero tolerance.

I'll give you the benefit of the doubt but keep the forum guidelines in mind. Anyway, most of the questions could be answered by yourself. If you download Oracle 10g XE (200MB) from otn.oracle.com you have a working version of the Oracle database and you can test for yourself. Good luck!

PS: The statement in the second question is not valid in Oracle.
