想知道在ORACLE中是否有更好的方法来编写以下PL/SQL代码?
IF(p_c_courtesies_cd is not null
OR p_c_language_cd is not null
OR v_c_name is not null
OR v_c_firstname is not null
OR v_c_function is not null
OR p_c_phone is not null
OR p_c_mobile is not null
OR p_c_fax is not null
OR v_c_email is not null
) THEN
-- Do something
END IF;
