in thread nested dbi queries question

i think i've narrows the problem to this line
$sql = "SELECT * FROM sp WHERE NOT EXISTS (SELECT * FROM SP,SUPPLIER WHERE SUPPLIER.snum = SP.snum)";
it's not finding any results. it's supposed to find all rows in table sp where sp.snum does not exist in table supplier
