Answer 1

seems to be working in 5.0.27, what is your version?

A view can be created from many kinds of SELECT statements. It can refer to base tables or other views. It can use joins, UNION, and subqueries. The SELECT need not even refer to any tables. The following example defines a view that selects two columns from another table, as well as an expression calculated from those columns: — http://dev.mysql.com/doc/refman/5.0/en/create-view.html
