If the action be one in which the defendant might have been arrested, as provided in ch. 818, an execution against the person of the judgment debtor may be issued after the return of an execution against the defendant's property unsatisfied in whole or in part; but if the defendant be imprisoned on execution in another action, or upon mesne process in the same action, an execution may issue against the defendant's body without any previous execution against the defendant's property.
