在选择语句SQL中使用TOP

Question

I'm trying to return only 10 rows, corresponding to the 10 vendors who've been paid the most but I can't seem to figure out how to use the TOP clause to grab the top 10 vendors who've been paid the most.

Select Top 10 SUM(PaymentTotal) AS PaymentSum, VendorName
From Invoices JOIN Vendors
On Vendors.VendorID = Invoices.VendorID
Group By VendorName;

;
