It looks like you're using database sessions but haven't loaded your database. Normally the session library will load the database for you. In ./application/config/config.php, make sure that $config['sess_table_name'] is not empty.

The query is executed very well, and who is deceive me that this error is showed only when I use the Hmvc architecture
thisis the session variables located in the config.php file:

$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_expire_on_close'] = TRUE;
$config['sess_encrypt_cookie'] = TRUE;
$config['sess_use_database'] = TRUE;
$config['sess_table_name'] = 'ci_sessions';
$config['sess_match_ip'] = FALSE;
$config['sess_match_useragent'] = TRUE;
$config['sess_time_to_update'] = 300;

Please post your controller code. I suspect you're not extending MX_Controller.
