移除书签DROP VIEW
Removes a view.
Synopsis
DROP VIEW [IF EXISTS] <name. [, ...] [CASCADE | RESTRICT]
Description
DROP VIEW will remove an existing view. Only the owner of a view can remove it.
Parameters
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.
CASCADE
Automatically drop objects that depend on the view (such as other views).
RESTRICT
Refuse to drop the view if any objects depend on it. This is the default.
Examples
Remove the view topten;
DROP VIEW topten;
Compatibility
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 HAWQ extension.
