You need to SUM

this summary value:
SELECT TOP 3 ProductID, SUM(Quantity) as qSum
FROM Table
GROUP BY ProductID
ORDER BY qSum DESC

I would like to display the top 3 records from the existing Orders table. In order to accomplish this, I need to calculate the sum of each product's quantity.
Existing Records:
OrderNo ProductID Quantity 1 1 50 1 2 30 1 3 20 2 2 30 3 1 100 3 4 50 4 1 20 4 5 10 5 2 10
Expected Output
ProductID Quantity 1 170 2 70 4 50
