dbx

hi there , i am interested to know more about dbx, especially the error handling $link = dbx_connect(DBX_MYSQL, "localhost", "db", "username", "password") or die ("Could not connect"); is there such an error feature where it can die to the screen with a custom error message instead of doing the error checking for every single query and connection ? and there is also no example of how to get a list of results like while ($row = $result->fetchRow()) { }
