怎么调用oracle存储过程，需要参数化

CREATE OR REPLACE procedure sp_score_pm(
p_in_stuid in varchar2,--学号
p_in_courseid in  varchar2, --课程ID
p_out_pm out number--排名
)
is
ls_score number:=0;

begin

  select t.score into ls_score from score t
   where t.stuid = p_in_stuid
     and t.courseid = p_in_courseid;

  select count(1) into ls_pm from score t
   where t.courseid = p_in_courseid
   and  t.score>ls_score;
   p_out_pm:=ls_pm+1;
exception
  when no_data_found  then
     dbms_output.put_line('该学生的课程：'||p_in_courseid|| '的成绩在成绩表中找不到');
end;
