For each Sales Order, show how many days it took to ship the order in order by the longest order, then by Sales Order Number. Display Sales Order Number and the number of days to ship. Include the orders that have not yet shipped. Hint: Look at the DATEDIFF function to return the difference between two dates. The two dates in this problem are the Order Date and the Shipment Date.
