What is the difference between derived table and views?
which one gives better performance?

Answer Posted / pradeep mishra

Always View is better than Derived Tabels because it
fetches the Data Directly through the Database So as per
the Performance related it's too good.
But,When we want to use @Function (@variable,@prompt) in
your Query that time it's only possible in Derived
Table,not in the VIEWS.
