Question

我已将SQL Server 2014与CodeIgniter连接。但是当我运行查询时，就会出现该错误。

这是给出错误的代码。

 function index()
  {
    $this->form_validation->set_rules('username', 'Username','required');
    $this->form_validation->set_rules('password', 'Password','required');
    if($this->form_validation->run() == TRUE)
    {
        $username = $_POST['username'];
        $password = $_POST['password'];
        $this->db->select('*');
        $this->db->from('student');
        $this->db->where(array('student_id'=>$username,'password'=>$password));
        $query = $this->db->get();
        $data = $this->db->result();
        if($data)
        {
          echo "<pre> ";
          print_r($data);
        }
    }
  $this->login('login');
  }
}

错误是

致命错误：调用未定义方法CI_DB_sqlsrv_driver :: result（）第14行上的D：\ Xampp \ htdocs \ CI_Portal \ application \ models \ my_model.php

Answer 1

尝试将$this->db->result();更改为$query->result();

$this->db->select('*');
$this->db->from('student');
$this->db->where(array('student_id' => $username, 'password' => $password));
$query = $this->db->get();
$data = $query->result();

实际获得表结果之后，结果资源就存在了。

或者您可以将其用作：

$data = $this->db->get()->result();

Answer 2

我尝试在application / config / database.php中进行配置更改

   $active_group = "default";
   $active_record = TRUE;
   $query_builder = TRUE;

并尝试使用清除缓存并尝试。

PHP Codeigniter调用未定义的方法CI_DB_sqlsrv_driver :: result（）
