NAME

       ALTER VIEW - change the definition of a view

SYNOPSIS

       ALTER VIEW name ALTER [ COLUMN ] column SET DEFAULT expression
       ALTER VIEW name ALTER [ COLUMN ] column DROP DEFAULT
       ALTER VIEW name OWNER TO new_owner
       ALTER VIEW name RENAME TO new_name
       ALTER VIEW name SET SCHEMA new_schema

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.

       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.

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.
