DROP 
VIEW(7)						  PostgreSQL 9.2.7 Documentation					      DROP VIEW(7)

NAME

       DROP_VIEW - remove a view

SYNOPSIS

       DROP VIEW [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

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

PARAMETERS

       IF EXISTS
	   Do not throw an error if the view does not exist. A notice is issued 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).

       RESTRICT
	   Refuse to drop the view if any objects depend on it. This is the default.

EXAMPLES

       This command will remove the view called kinds:

	   DROP VIEW kinds;

COMPATIBILITY

       This command conforms to the SQL standard, except that the standard only allows one view to be dropped per command, and apart from the IF
       EXISTS option, which is a PostgreSQL extension.

NAME

       ALTER_VIEW - change the definition of a view

SYNOPSIS

       ALTER VIEW [ IF EXISTS ] name ALTER [ COLUMN ] column_name SET DEFAULT expression
       ALTER VIEW [ IF EXISTS ] name ALTER [ COLUMN ] column_name DROP DEFAULT
       ALTER VIEW [ IF EXISTS ] name OWNER TO new_owner
       ALTER VIEW [ IF EXISTS ] name RENAME TO new_name
       ALTER VIEW [ IF EXISTS ] name SET SCHEMA new_schema
       ALTER VIEW [ IF EXISTS ] name SET ( view_option_name [= view_option_value] [, ... ] )
       ALTER VIEW [ IF EXISTS ] name RESET ( view_option_name [, ... ] )

DESCRIPTION

       ALTER VIEW changes various auxiliary properties of a view. (If you want to modify the view's defining query, use CREATE OR REPLACE VIEW.)

       You must own the view to use ALTER VIEW. To change a view's schema, you must also have CREATE privilege on the new schema. To alter the
       owner, you must also be a direct or indirect member of the new owning role, and that role must have CREATE privilege on the view's schema.
       (These restrictions enforce that altering the owner doesn't do anything you couldn't do by dropping and recreating the view. However, a
       superuser can alter ownership of any view anyway.)

PARAMETERS

       name
	   The name (optionally schema-qualified) of an existing view.

       IF EXISTS
	   Do not throw an error if the view does not exist. A notice is issued in this case.

       SET/DROP DEFAULT
	   These forms set or remove the default value for a column. A default value associated with a view column is inserted into INSERT
	   statements on the view before the view's ON INSERT rule is applied, if the INSERT does not specify a value for the column.

       new_owner
	   The user name of the new owner of the view.

       new_name
	   The new name for the view.

       new_schema
	   The new schema for the view.

       view_option_name
	   The name of a view option to be set or reset.

       view_option_value
	   The new value for a view option.

NOTES

       For historical reasons, ALTER TABLE can be used with views too; but the only variants of ALTER TABLE that are allowed with views are
       equivalent to the ones shown above.

EXAMPLES

       To rename the view foo to bar:

	   ALTER VIEW foo RENAME TO bar;

COMPATIBILITY

       ALTER VIEW is a PostgreSQL extension of the SQL standard.
