一、任务提出
JAVA操作oracle11g存储过程实验需要完成以下几个实例：
1.调用没有返回参数的过程（插入记录、更新记录）
2.有返回参数的过程
3.返回列表的过程
4.返回带分页的列表的过程。
二、建立表和相应的存储过程
create table student (sno int ,sname varchar2(20),sage int);
--创建存储过程testa1
create or replace procedure testa1(para1 in int,para2 in varchar2,para3 in int)
is
begin
insert into student(sno,sname,sage) values(para1,para2,para3);
commit;
end;
/
--创建存储过程testa2
create or replace procedure testa2(para1 in int,para2 in int)
is
begin
update student set sage=para2 where sno=para1;
commit;
end;
/
--创建有返回参数的存储过程testb
create or replace procedure testb(para1 in int ,para2 out varchar2,para3 out int)
is
begin
select sname,sage into para2,para3 from student where sno=para1;
end;
--创建返回集合的存储过程：
--在oracle中，如果要返回集合必须是返回游标，不能是一张二维表。所以，要先建立包。
create or replace package testpack
is
type test_cursor is ref cursor;
end testpack;
/
create or replace procedure testc(p_cursor out testpack.test_cursor)
is
begin
open p_cursor for select * from student;
end;
/
--实现分页的存储过程
---ps 每页几个记录，cs第几页
create or replace procedure testd(ps int ,cs int ,p_cursor out testpack.test_cursor)
is
begin
open p_cursor for
select * from (select student.*,rownum rn from student) where rn>ps*(cs-1) and rn<=ps*cs;
end;
/
三、java操作调用上述存储过程
package com.oaj;
import java.sql.*;
import com.sun.org.apache.xalan.internal.xsltc.compiler.util.Type;

String driver="oracle.jdbc.driver.OracleDriver";

{

}

{
try
{
Class.forName(driver);
conn=DriverManager.getConnection(strUrl,"scott","scott");
cstmt=conn.prepareCall("{ call scott.testd(?,?,?)}");
cstmt.registerOutParameter(3, oracle.jdbc.OracleTypes.CURSOR);//指定是oracle里规定的类型
cstmt.setInt(1,recordPerPage);
cstmt.setInt(2, currentPage);
cstmt.execute();
rs=(ResultSet)cstmt.getObject(3);
while(rs.next())
{
