php - 在codeigniter中获取不同数据库的select查询结果

Question

我在我的database.php中声明了两个数据库，我如何访问db和db2实例的用户列表

        //database initialisation 
        $CI =& get_instance();
        $CI->db1 = $CI->load->database('default', TRUE);
        $CI->db2 = $CI->load->database('stylior_db', TRUE);
         //select query for db2
    $this->$db2->from('users');
    // $this->$CI->db2->where('id',1312);

    $query = $this->$CI->db2->get();
    print_r($query);

    if ( $query->num_rows() > 0 )
    {
        $row = $query->row_array();
        return $row;
    }

试试这个方法

    $db_result = $this->db->get("table_users"); // here default database connected
    $this->db1 = $this->load->database('db1', TRUE);    
    $db1_result = $this->db1->get("table_users")
