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.
In MySQL 8.4 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 9.0, a partially completed
DROP VIEW
operation on a MySQL
8.4 replication source server fails when
replicated on a MySQL 9.0 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 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, a
NOTE
is generated for each nonexistent view.
See Section 15.7.7.41, “SHOW WARNINGS Statement”.
RESTRICT
and CASCADE
, if
given, are parsed and ignored.
