四、JDBC JAVA调用 oracle存储过程 返回游标

出自http://blog.csdn.net/zhaoweitco/article/details/5479200


1.创建测试表

create table users(
userid int primary key,
username varchar2(20),
userpwd  varchar2(20)
);

insert into users values(1,'test','test');
insert into users values(2,'test','test');
insert into users values(3,'test','test');
insert into users values(4,'test','test');
insert into users values(5,'test','test');
insert into users values(6,'test','test');
insert into users values(7,'test','test');



2.创建存储过程

创建包

create or replace package pkg_test
as
  type cursor0 is ref cursor;
  procedure get(p_id int,p_rc out cursor0);
end pkg_test;



创建包的内容
create or replace package body pkg_test as
  procedure get(p_id int, p_rc out cursor0) is
  begin
    dbms_output.put_line(p_id);
    open p_rc for
      select userid, username, userpwd from users;
  end get;
end pkg_test;



3.java调用

package com.wei;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;

/***
*
* 测试 jdbc 连接 oracle 存储过程 返回游标
*
* @author wei
*
*/
public class Main {

public static void main(String[] args) {
  try {
   DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
   Class.forName("oracle.jdbc.driver.OracleDriver");
   String url = "jdbc:oracle:thin:@127.0.0.1:1521:wei";
   String username = "test";
   String password = "admin";
   Connection conn = DriverManager.getConnection(url, username,
     password);
   String sql = "{call pkg_test.get(?,?)}";
   CallableStatement cstmt = conn.prepareCall(sql);
   cstmt.setInt(1, 1);
   cstmt.registerOutParameter(2, oracle.jdbc.OracleTypes.CURSOR);
   cstmt.execute();
   ResultSet rs = (ResultSet) cstmt.getObject(2);
   while (rs.next()) {
    System.out.println(rs.getInt(1) + "/t" + rs.getString(2) + "/t"
      + rs.getString(3));
   }
  } catch (SQLException e) {
   e.printStackTrace();
  } catch (ClassNotFoundException e) {
   e.printStackTrace();
  }
}

}

输出结果：

1 test test
2 test test
3 test test
4 test test
5 test test
6 test test
7 test test
