function sess_write()
    {
        // Are we saving custom data to the DB?  If not, all we do is update the cookie
        if ($this->sess_use_database === FALSE)
        {
            $this->_set_cookie();
            return;
        }

        // set the custom userdata, the session data we will set in a second
        $custom_userdata = $this->userdata;
        $cookie_userdata = array();

        // Before continuing, we need to determine if there is any custom data to deal with.
        // Let's determine this by removing the default indexes to see if there's anything left in the array
        // and set the session data while we're at it
        foreach (array('session_id','ip_address','user_agent','last_activity') as $val)
        {
            unset($custom_userdata[$val]);
            $cookie_userdata[$val] = $this->userdata[$val];
        }

        // Did we find any custom data?  If not, we turn the empty array into a string
        // since there's no reason to serialize and store an empty array in the DB
        if (count($custom_userdata) === 0)
        {
            $custom_userdata = '';
        }
        else
        {
            // Serialize the custom data array so we can store it
            $custom_userdata = $this->_serialize($custom_userdata);
        }
        // Run the update query
        $this->CI->db->where('session_id', $this->userdata['session_id']);
        $this->CI->db->update($this->sess_table_name, array('last_activity' => $this->userdata['last_activity'], 'user_data' => $custom_userdata));

        // Write the cookie.  Notice that we manually pass the cookie data array to the
        // _set_cookie() function. Normally that function will store $this->userdata, but
        // in this case that array contains custom data, which we do not want in the cookie.
        $this->_set_cookie($cookie_userdata);
    }

Answer 1

创建一个名为ci_sessions 的表，然后重试

Answer 2

 $this->CI->load->database('databasename', TRUE);
