DROP VIEW Syntax
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, MariaDB returns an error indicating by name which nonexisting 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 nonexistent view. See , "SHOW WARNINGS Syntax".
RESTRICT and CASCADE, if given, are parsed and ignored.
