第一步：通过考号，判断是否有此考生的信息
create or replace procedure logon ( temp in int)
as
a1 int:=0;
begin
select distinct sid*1 into a1 from stu_info where sid=temp;
if a1>0 then
dbms_output.put_line('login success !');
end if;
end;
/
第二步：通过考号，查询考生的总分
create or replace procedure sumscore( temp in int)
as
a1 int:=0;
begin
select sum(oscore) into a1 from stu_score where sid=temp;
dbms_output.put_line('sum:'||a1);
end;
/
第三步：通过考号得到总分，能够查询到够分数线的学校信息（未安省份查询）
create or replace procedure school( temp in int)
as
begin
declare
cursor cur is (select * from sch_info where hscore<(select sum(oscore) from stu_score where sid=temp));
school sch_info%rowtype;
begin
open cur;
loop
fetch cur into school;
exit when cur%notfound;
dbms_output.put_line(school.hname);
end loop;
close cur;
end;
end;

以后会有新的功能代码添加到本博客中，请大家谅解，一个人不能把一个系统在短时间内完成它
