JAVA操作ORACLE數據庫的存儲過程

一、任務提出

JAVA操作oracle11g存儲過程實驗需要完成以下幾個實例：

1.調用沒有返回參數的過程（插入記錄、更新記錄）

2.有返回參數的過程

3.返回列表的過程

4.返回帶分頁的列表的過程。

二、建立表和相應的存儲過程

 

create table student (sno int ,sname varchar2(20),sage int);

--創建存儲過程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;
/
--創建存儲過程testa2
create or replace procedure testa2(para1 in int,para2 in int)
is
begin
     update student set sage=para2 where sno=para1;
     commit;
end;
/
--創建有返回參數的存儲過程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;
--創建返回集合的存儲過程：
--在oracle中，如果要返回集合必須是返回游標，不能是一張二維表。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;
/

 

--實現分頁的存儲過程
---ps 每頁幾個記錄，cs第幾頁
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操作調用上述存儲過程

 

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";

    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里規定的類型
            cstmt.setInt(1,recordPerPage);
            cstmt.setInt(2, currentPage);
            cstmt.execute();
            rs=(ResultSet)cstmt.getObject(3);
            
            while(rs.next())
            {
                System.out.print("學號是："+rs.getInt(1)+"的學生的名字是："+rs.getString(2)+",年齡是："+rs.getInt(3)+"\r\n");
            }
        }
        catch(SQLException ex)
        {

        }
        catch(Exception ex)
        {

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

            {
                ex.printStackTrace();
            }
        }
    }

            }
