procedure can't return a result set in the given context

调用存储过程失败！出现如下错误：PROCEDURE ipbx.qu_ery can't return a result set in the given context，

ipbx是数据库，
qu_ery是自己写的存储过程的名字；

原因：连接数据库的方式不正确。

导致报错的连接方式： 

<?php
if(!mysql_real_connect(&mysql,"localhost","root","123456","ipbx",0,NULL,0))
        {
                printf("mysql_real_connect() failed!/n");
                mysql_close(&mysql);
                return 0;
        }
正确的连接方式：

<?php
if(!mysql_real_connect(&mysql,"localhost","root","123456","ipbx",0,NULL,CLIENT_MULTI_STATEMENTS))
         {
                printf("mysql_real_connect() failed!/n");
                mysql_close(&mysql);
                return 0;
        }
修改一下连接数据库的方式的参数就OK了！

你修改一下
system/database/drivers/mysql/mysql_driver.php

function db_connect()
    {
    define("CLIENT_MULTI_RESULTS",131072);//Enable/disable multi-results
    define("CLIENT_MULTI_STATEMENTS",65536);//Enable/disable multi-statement support

    return @mysql_connect($this->hostname, $this->username, $this->password, TRUE,CLIENT_MULTI_STATEMENTS);
    }

To retrieve multiple resultsets from the stored procs, you should use a client which supports multiple queries.

If you use PHP, use MySQLi extension and call the procedure using mysqli_multi_query.

MySQL extension is only able to retrieve the first recordset returned by the proc. To be able to use ti, you should set CLIENT_MULTI_RESULTS (decimal 131072) in the parameter $client_flags tomysql_connect

codeigniter 调用存储过程出错 

关键就是两点
　　1）define('CLIENT_MULTI_RESULTS', 131072);
　　2）$link = mysql_connect("127.0.0.1", "root", "",1,CLIENT_MULTI_RESULTS) or die("Could not connect: ".mysql_error());
