How to find products without manufacturer?

[matteoraggi]

In the past I was deleting a manufacturer, leaving the products on the cart, but now I would like to add back these products to them manufacturer, but I can't find them easily between many others.
These products are different from others, because without manufacturer. Is there a tip or module to find them quickly?

For products without a manufacturer set you could go to phpMyAdmin and run the SQL statement for:

SELECT * FROM products WHERE manufacturers_id = 0;
