Syntax:
DROP VIEW [IF EXISTS]
    view_name [, view_name] ...
    [RESTRICT | CASCADE]

DROP VIEW removes one or more views. You must have the DROP privilege
for each view.

If any views named in the argument list do not exist, the statement
returns an error indicating by name which nonexisting views it was
unable to drop, but also drops all views in the list that do exist.

The IF EXISTS clause prevents an error from occurring for views that
don't exist. When this clause is given, a NOTE is generated for each
nonexistent view. See [HELP SHOW WARNINGS].

RESTRICT and CASCADE, if given, are parsed and ignored.
