[MySQL][PHP] problem z zapytaniem Opcje

[jjarkus]

Dręczy mnie pewien problem z moim kodem (IMG:style_emoticons/default/blinksmiley.gif)
Mianowicie tworzę sobie taką małą grę i problem jest następujący:
Podczas rejestracji nowego użytkownika wyskakuje taki błąd:

Kod

         Warning:  mysql_fetch_row(): supplied argument is not a valid MySQL result resource in c:\usr\krasnal\www\gra\stats.php on line 43
         Warning:  mysql_fetch_row(): supplied argument is not a valid MySQL result resource in c:\usr\krasnal\www\gra\stats.php on line 43
         Warning:  mysql_fetch_row(): supplied argument is not a valid MySQL result resource in c:\usr\krasnal\www\gra\stats.php on line 43

Skorzystałem też z

[PHP] pobierz, plaintext 
 echo mysql_error();
[PHP] pobierz, plaintext 

i pokazał taki komunikat:

Kod

         Something is wrong in your syntax obok 'SELECT id FROM stats WHERE display_name = 'mag' OR short_name = ' w linii 1

Wychodzi na to, że chyba wykonanie zapytania się nie powiodło.
W czym może tkwić błąd?

Dobra zrobiłem tak i wszystko działa teraz pięknie:
stats.php

[PHP] pobierz, plaintext 
function getAvatar($avatar,$userID) {
        $query = sprintf("SELECT avatar FROM users WHERE UPPER(username) = UPPER('%s')",
        mysql_real_escape_string($_SESSION['username']),
        mysql_real_escape_string($query));
        $result = mysql_query($query);
        list($avatar) = mysql_fetch_row($result);
        return $avatar;
}

index.php

[PHP] pobierz, plaintext 
$smarty->assign('avatar',getAvatar($avatar,$userID));
[PHP] pobierz, plaintext 

index.tpl

[XML] pobierz, plaintext 
<img src="{$avatar}"/>
[XML] pobierz, plaintext 

I awatary się wyświetlają (IMG:style_emoticons/default/guitar.gif)
A jak zrobić żeby przy rejestracji, jak się nic nie wpisze w pole awatar, aby w tablicy został podany adres domyślny awatara dla nowego usera?
