Can I combine these 2 queries into 1?

[Erwin]

Thanks for helping in advance.

PHP Code:


$top=$DB_site->query_first("SELECT userid,field10 FROM userfield WHERE userid!=0 ORDER BY field10 desc LIMIT 5");

$topname=$DB_site->query_first("SELECT username,userid FROM user WHERE userid=$top[userid]"); 


I tried to use the JOIN command, but I keep ending up making loops. Thanks for helping again.
