I think that a view _is_, in fact, the same as a static select/omit access
path, sans ordering, since it is a logical file, whose access path will be
maintained as any other logical file. Couldn't the implementation, then, be
SELECT * FROM view ORDER BY fieldlist, where the ORDER BY matches the index
(or some other keyed logical file)? I don't know what the SQL engine will
do under the covers.
