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.
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.
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 Section 13.7.5.40, “SHOW WARNINGS Statement”.
RESTRICT
and CASCADE
, if
given, are parsed and ignored.
