如果存储过程编译错误，用什么命令获得错误信息
create or replace procedure proc_count_age
as
count1 tb_stu_info%type;
begin
declare cursor c_count is select (case when a.age>=30 and a.age<=39 then '30-39'
when a.age>=40 and a.age<=50 then '40-50'
when a.age<30 then '<30'
else '>50' end) age,count(*)人数
from (select to_number(to_char(sysdate,'yyyy'))-to_number(substr(birth,1,4)) age
from tb_stu_info,dual)a group by
(case when a.age>=30 and a.age<=39 then '30-39'
when a.age>=40 and a.age<=50 then '40-50'
when a.age<30 then '<30'
else '>50' end);
begin
DBMS_OUTPUT.PUT_LINE('年龄段 人数');
for count1 in c_count loop
DBMS_OUTPUT.PUT_LINE(count1.age||' '||count1.人数);
end loop;
end;
end;
/
过程是这样的，哪不对呀
