"Example of DROP MATERIALIZED VIEW"
The DROP MATERIALIZED VIEW statement drops a materialized view. You cannot drop a
materialized view that is used by other materialized views or by regular views unless the
CASCADE option is used. This command removes the materialized view from all the MVGROUPs
it belongs to. It could cause recompilation of SQL statements that used the materialized view,
as well as any of its base tables.
DROP { MATERIALIZED VIEW | MV } mv-name [CASCADE]
Syntax Description of DROP MATERIALIZED VIEW
mv-name
specifies the ANSI logical name for the materialized view to drop of the form:
[schema-name.]mv-name
where each part of the name is a valid SQL identifier with a maximum of 128 characters.
mv-name must be unique among table, view, and procedure names in the schema. For more
information, see
CASCADE
any objects that depend on the materialized view are dropped. This includes materialized
views and views.
Authorization and Availability Requirements
To drop a materialized view, you must be the owner of the schema or the owner of the
materialized view.
