Oracle 10g does not support the ANSI EXCEPT operator. It does support 
UNION and INTERSECT. However, it does not support the use of the ALL 
keyword with those set operators. However, Oracle does intend to support 
all the ANSI set operators and their keywords in a future release.

A minor note -- you really meant Oracle 10g, not 10i
