I am just curious if its common for an Explain Plan of a view to have a totally different response than an explain plan of the SQL behind the view.
Reason being, we have a very simple view made of of 3 tables that, when you explain it, it shows full table scans on all three tables. But, in the mean time, if you explain plan the SQL behind the view, you get index range scans on all three tables.
Just makes no sense to me (which seems to be happneing more and more these days).
