DROP VIEW

Function

DROP VIEW forcibly deletes a view from the database.

Precautions

Only the view owner or a user granted with the DROP permission can run the DROP VIEW command. The system administrator has this permission by default.

Syntax

DROP VIEW [ IF EXISTS ] view_name [, ...] [ CASCADE | RESTRICT ];

Parameter Description

• IF EXISTS

  Reports a notice instead of an error if the specified view does not exist.

• view_name

  Specifies the name of the view to be deleted.

  Value range: an existing view name

• CASCADE | RESTRICT

  • CASCADE: automatically deletes the objects (such as other views) that depend on the view.
  • RESTRICT: refuses to delete the view if any objects depend on it. This is the default action.
