--使用存储过程
--创建无参存储过程
create or replace procedure showAllStudentInfo
--参数变量
as
--自定义变量
s_name varchar(20);
s_score number(6);
cursor cur_student is select * from student;
begin
  dbms_output.put_line('您调用了showAllStudentInfo...');
  for c_student in cur_student loop

    dbms_output.put_line(s_name||':'||s_score);
  end loop;
