Deletes the field from the relation. This option deletes the field only from the relation definition. The global field definition by this name is still defined for the database as a whole, and other relations can still refer to it. If an existing view, index, constraint, or computed field refers to the field, Oracle Rdb returns an error when you try to delete it.
