The create view does not access the data at all. It just create an object in
the data dictionary.
What you need to compare is 'select * from view' against doing the select
from sqlplus.

So why would the sql statement used to create a view run faster

David,
A view is a STORED object, which means that it executes using a plan
which was
Run autotrace or sql_trace and determine if the execution plans are
different. If they are the same, increase the sql_trace level and find
out what the wait events are.
