Select product, enter productivity on the product. Productivity = orderline.producted where not present (orderline from orderline. Select the product type) Order by the producer

You can only export PRODUCT. PRODUCT WITH LEFT JOINSERLINE USING (productid) WHERE orderline.productid is the order of by product. All of the rows in productid

LEFT JOIN list product , even if the orderline . In that case, orderline contains all the columns in the NULL values ​​that are the ones that you want in the result.
