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.
