Redefining a view

Unlike inserting and updating, redefining a view doesn't mean modifying the actual data a view holds. Rather, it means modifying the underlying query that makes the view. In the last video, we learned of two ways to redefine a view: (1) CREATE OR REPLACE and (2) DROP then CREATE. CREATE OR REPLACE can only be used under certain conditions.

The artist_title view needs to be appended to include a column for the label field from the labels table.
