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 of the views named in the argument list do not
exist, MySQL returns an error indicating by name which non-existing
views it was unable to drop, but it also drops all of the 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
non-existent view. See [HELP SHOW WARNINGS].

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