Removes a view.
DROP VIEW [IF EXISTS] name [, ...] [CASCADE | RESTRICT]
DROP VIEW will remove an existing view. Only the owner of a view can remove it.
- IF EXISTS
- Do not throw an error if the view does not exist. A notice is issued in this case.
- The name (optionally schema-qualified) of the view to remove.
- Automatically drop objects that depend on the view (such as other views).
- Refuse to drop the view if any objects depend on it. This is the default.
Remove the view topten;
DROP VIEW topten;
DROP VIEW is fully conforming with the SQL standard, except that the standard only allows one view to be dropped per command. Also, the IF EXISTS option is a Greenplum Database extension.
