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
fails with an error indicating by name which nonexisting views it was
unable to drop, and no changes are made.

*Note*:

In MySQL 8.3 and earlier, DROP VIEW returns an error if any views named
in the argument list do not exist, but also drops all views in the list
that do exist. Due to the change in behavior in MySQL 8.4, a partially
completed DROP VIEW operation on a MySQL 8.3 replication source server
fails when replicated on a MySQL 8.4 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 https://dev.mysql.com/doc/refman/8.4/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.
