Come utilizzare l'API Table?

Supponiamo ora di voler eliminare un record dipendente dalla tabella Employees, quindi utilizzare la procedura API del pacchetto EMPLOYEES_TAPI.DEL come segue:

DECLARE 
  P_EMPLOYEE_ID NUMBER;

BEGIN 
  P_EMPLOYEE_ID := 105;

  EMPLOYEES_TAPI.DEL ( P_EMPLOYEE_ID );
  COMMIT; 
END;
