# DROP DOMAIN

## Name

DROP DOMAIN -- remove a domain

## Description

`DROP DOMAIN` will remove a domain. Only the owner of a domain can remove it.

## Parameters

`name`

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

`CASCADE`

  Automatically drop objects that depend on the domain (such as table columns).

`RESTRICT`

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

## Examples
