JAVA操作ORACLE数据库的存储过程

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;

public class Test {
    String driver="oracle.jdbc.driver.OracleDriver";
    String strUrl="jdbc:oracle:thin:@localhost:1521:orcl";
    ResultSet rs=null;
    Connection conn=null;

    CallableStatement cstmt=null;

    public static void main(String[] args)
    {
        new Test().testPageSet(3,1);
    }
    public void testPageSet(int recordPerPage,int currentPage)
    {
        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())
            {
                System.out.print("学号是："+rs.getInt(1)+"的学生的名字是："+rs.getString(2)+",年龄是："+rs.getInt(3)+"\r\n");
            }
        }
        catch(SQLException ex)
        {
            ex.printStackTrace();
        }
        catch(Exception ex)
        {
            ex.printStackTrace();

        }
        finally
        {
            try
            {
                if(cstmt!=null)
                    cstmt.close();
                if(conn!=null)
                {
                    conn.close();
                    conn=null;
                }

            }
            catch(SQLException ex)
            {
                ex.printStackTrace();
            }
        }
    }
    public void testOutResult()
    {
        try
        {
            Class.forName(driver);
            conn=DriverManager.getConnection(strUrl,"scott","scott");
            cstmt=conn.prepareCall("{ call scott.testc(?)}");
