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.

*Note*:

In MySQL 8.0, DROP VIEW fails if any views named in the argument list
do not exist. Due to the change in behavior, a partially completed DROP
VIEW operation on a MySQL 5.7 source fails when replicated to a MySQL
8.0 replica. To avoid this failure scenario, use IF EXISTS syntax in
DROP VIEW statements to prevent an error from occurring for views that
do not exist. For more information, see Atomic Data Definition
Statement Support
(https://dev.mysql.com/doc/refman/8.0/en/atomic-ddl.html).

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.
