solve nested .. not in (select ..) ?!

I can read in the manual that these nested queries cannot be made. However there is no example on how to solve my problem w/o nesting:

select * from product where prodId not in (select catProdId from categoryMember)

What I want, obviously, is to show all products not being member of any category.

Thnx for any tips,

It is possible to rewrite this subselect as a left join....

select product.*
from product LEFT JOIN categoryMember
ON product.prodID=categoryMember.catProdID
WHERE categoryMember.catProdID IS NULL;
