Java 返回结果集的存储过程

--返回结果集的存储过程
--1.创建一个包
create package myTestPackage as
type test_cursor is ref cursor;
end myTestPackage;

--2.创建存储过程
create procedure sp_pro9(
       spNo in number,
       p_cursor out myTestPackage.test_cursor) is
begin
  open p_cursor for 
       select * from student where classId=spNo; 
end;

--3.在Java中调用
