Removes a view.
DROP VIEW [IF EXISTS] <name> [, ...] [CASCADE | RESTRICT]
DROP VIEW removes 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. Apache Cloudberry issues a notice in this case.
name
The name (optionally schema-qualified) of the view to remove.
CASCADE
Automatically drop objects that depend on the view (such as other views), and in turn all objects that depend on those objects.
RESTRICT
Refuse to drop the view if any objects depend on it. This is the default.
Remove the view topten:
DROP VIEW topten;
DROP VIEW fully conforms to the SQL standard, except that the standard only allows one view to be dropped per command. Also, the IF EXISTS option is a Apache Cloudberry extension.
