php - 尝试使用 CodeIgniter 存储过程 'call'

Question

我有 CI 的工作代码:

$this->db->query("call nameOfProcedure('param1', @param2)");
$query = $this->db->query('SELECT @param2 as results');
$row = $query->row();

它有效，但如果我尝试使用:

$this->db->call_function('nameOfProcedure', 'param1', '@param2');

我得到错误:

This feature is not available for the database you are using.

到底出了什么问题？

谢谢

以防万一它能帮助到任何人。我使用这个库在 CI 中处理存储过程，它也支持多个结果集。

这是代码

我称之为Mydb.php

<?php #if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Mydb
{
   private $CI, $Data, $mysqli, $ResultSet;

   /**
   * The constructor
   */

   function __construct()
   {
     $this->CI =& get_instance();
     $this->Data = '';
     $this->ResultSet = array();
     $this->mysqli = $this->CI->db->conn_id;
   }

    public function GetMultiResults($SqlCommand)
    {
    /* execute multi query */
    if (mysqli_multi_query($this->mysqli, $SqlCommand)) {
        $i=0;
        do
        {

             if ($result = $this->mysqli->store_result()) 
             {
                while ($row = $result->fetch_assoc())
                {
                    $this->Data[$i][] = $row;
                }
                mysqli_free_result($result);
             }
            $i++; 
        }
        while ($this->mysqli->next_result());
    }
    return $this->Data;

   }   
}
?>  

从 Controller 中这样调用它

$this->load->library('mydb');
$arr  = $this->mydb->GetMultiResults("CALL GetReferrals()");

此外，确保设置 mysqli 驱动程序在 application/config/database.php

$db['default']['dbdriver'] = 'mysqli';
