DROP_VIEW(l)                                         DROP_VIEW(l)

NAME
       DROP VIEW - Removes an existing view from a database

SYNOPSIS
       DROP VIEW name

   INPUTS
       name   The name of an existing view.

   OUTPUTS
       DROP   The  message returned if the command is successful.

       ERROR: RewriteGetRuleEventRel: rule "_RETname" not found
              This message occurs if the specified view does  not
              exist in the database.

DESCRIPTION
       DROP  VIEW  drops  an existing view from the database.  To
       execute this command you must be the owner of the view.

   NOTES
       The Postgres DROP TABLE statement also drops views.

       Refer to CREATE VIEW for  information  on  how  to  create
       views.

USAGE
       This command will remove the view called kinds:

       DROP VIEW kinds;

COMPATIBILITY
   SQL92
       SQL92  specifies  some  additional  capabilities  for DROP
       VIEW:

       DROP VIEW view { RESTRICT | CASCADE }

   INPUTS
       RESTRICT
              Ensures that only a view with no dependent views or
              integrity constraints can be destroyed.

       CASCADE
              Any  referencing  views  and  integrity constraints
              will be dropped as well.

   NOTES
       At present, to remove a referenced view  from  a  Postgres
       database, you must drop it explicitly.
