Dalam application/config/database.php atur

// suppress error output to the screen
$db['default']['db_debug'] = FALSE;

Dalam model atau pengontrol Anda:

// try the select.
$dbRet = $this->db->select($table, $dataArray);
// select has had some problem.
if( !$dbRet )
{
   $errNo   = $this->db->_error_number();
   $errMess = $this->db->_error_message();
   // Do something with the error message or just show_404();
}
