15.1.35 DROP VIEW Statement

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 completedDROP 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 inDROP VIEW statements to prevent an error from occurring for views that do not exist. For more information, see Section 15.1.1, “Atomic Data Definition Statement Support”.

The IF EXISTS clause prevents an error from occurring for views that don't exist. When this clause is given, aNOTE is generated for each nonexistent view. See Section 15.7.7.42, “SHOW WARNINGS Statement”.

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