SQL Selecting multiple sums?

Question

Let\'s say I have a table:

SELECT  SUM(quantity) AS items_sold_since_date,
        product_ID
FROM    Sales
WHERE order_date >= \'01/01/09\'
GROUP BY product_         


        

Answer 1

If you like to see total sales alongside, then you would use sum(sale_amt), and in the group by add the sale_amt. I hope it helps.
