建表：

create table student ( username varchar(20), pass varchar(20) );



--插入数据存贮过程
create or  replace procedure test_stu( param1  IN varchar2)  as

begin 


   insert into student(username) values (param1);

end test_stu;


--有返回字段值的存贮过程
create or  replace procedure test_stu_backpass(param_in IN varchar2,param_out OUT varchar2)  as

begin 

   select pass into param_out from student where username= param_in; 

end test_stu_backpass;
