Removes a materialized view.

Synopsis

DROP MATERIALIZED VIEW [ IF EXISTS ] <name> [, ...] [ CASCADE | RESTRICT ]

DROP MATERIALIZED VIEW drops an existing materialized view. To run this command, you must be the owner of the materialized view.

IF EXISTS
- Do not throw an error if the materialized view does not exist. A notice is issued in this case.
name
- The name (optionally schema-qualified) of a materialized view to be dropped.
CASCADE
- Automatically drop objects that depend on the materialized view (such as other materialized views, or regular views), and in turn all objects that depend on those objects.
RESTRICT
- Refuse to drop the materialized view if any objects depend on it. This is the default.

This command removes the materialized view called order_summary.

DROP MATERIALIZED VIEW order_summary;
