But this would be an Oracle forum, correct? ;-)

Robert,
Oracle wasn't mentioned in the original question. And as you have said default
transaction isolation level is different from database to database. Person with
Sybase background might answer yes, but that doesn't mean he is bad.

I expect them to understand that Oracle does not do dirty reads (unlike, DB2 or
SQL Server by default). That user a will not see user b's changes until user b

of this process.
I'd like to know how you think the answer to this could be wrong answers in
general? Dirty reads do not exist in Oracle, period.
