You are right.

I have re-organise the code and use db transactions to fitful my needs.

Anyway, I need sometimes to handle MySQL error (for example, handling duplicated username insert) and those two function do the job:

Code:

$errtxt = $this->db->_error_message();
$errno = $this->db->_error_number();

Thank You all for support.
