DROP VIEW

Function

DROP VIEW forcibly deletes an existing view in a database.

Precautions

• Only a view owner or a system administrator can run DROP VIEW command.
• The database stores only the definition of a view, but does not store the data corresponding to the view. If the base table remains unchanged, you can run the CREATE VIEW command to recreate a view that is deleted by mistake.

Syntax

1

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

Parameter Description

• IF EXISTS

  Sends 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.

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

Examples
