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.zhwy;

import java.sql.*;

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);
    }

    /**
     * 没有返回参数的存储过程
     * @param inputeSno
     * @param inputSage
     */
    public void testNoOutParameterUpdate(int inputeSno, int inputSage) {
        try {
            Class.forName(driver);
            conn = DriverManager.getConnection(strUrl, "scott", "scott");
            cstmt = conn.prepareCall("{ call scott.testa2(?,?)}");
            cstmt.setInt(1, inputeSno);
            cstmt.setInt(2, inputSage);
            cstmt.execute();
            System.out.println("执行成功！");
        } 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();
            }
        }
    }
    
    /**
     * 没有返回参数的存储过程
     * @param inputeSno
     * @param inputSage
     */
    public void testNoOutParameterInsert(int a, String b, int c) {
        try {
            Class.forName(driver);
            conn = DriverManager.getConnection(strUrl, "scott", "scott");
            cstmt = conn.prepareCall("{ call scott.testa1(?,?,?)}");
            cstmt.setInt(1, a);
            cstmt.setString(2, b);
            cstmt.setInt(3, c);
            cstmt.execute();
        } catch (SQLException ex) {
            ex.printStackTrace();
        } catch (Exception ex) {

        }
    }
