[piero.mac]

hai capito malissimo.

mysql_query("set @value = 0"); 

$update = mysql_query("UPDATE tracklist 
                       SET countview=countview+1 
                       WHERE trackid='".$_GET['trackid']."' 
                       AND
                       @value := countview+1"); 

$res = mysql_query("select @value");

$row = mysql_fetch_row($res);

echo $row[0];
