Answer to Question 1

FALSE

Answer to Question 2

A derived table can be created by placing a subquery within the FROM clause. The derived table is simply a temporary table in memory which can be accessed just like a table or view. Sometimes, these are referred to as inline views. A derived table is useful for situations where you need to create aggregate values (such as a sum) and then use these in another query. A derived table would be used instead of a subquery in cases where you need to display results from multiple tables. If the results need to come from a subselect, this is not possible, so we would have to use a derived table.
