For every order that has been received, display the order ID, the total dollar amount owed on that order (you'll have to calculate this total from attributes in one or more tables; label this result TotalDue), and the amount received in payments on that order (assume that there is only one payment made on each order). To make this query a little simpler, you don't have to include those orders for which no payment has yet been received. List the results in decreasing order of the difference between total due and amount paid.
