Jak korzystać z API tabel?

Załóżmy teraz, że chcesz usunąć rekord pracownika z tabeli Pracownicy, a następnie użyć procedury API pakietu EMPLOYEES_TAPI.DEL w następujący sposób:

DECLARE 
  P_EMPLOYEE_ID NUMBER;

BEGIN 
  P_EMPLOYEE_ID := 105;

  EMPLOYEES_TAPI.DEL ( P_EMPLOYEE_ID );
  COMMIT; 
END;
