Sort the order of the results from OrderId.
NOT depend on the default schema of a user.
Use an alias of TotalSales for the calculated ExtendedAmount.
Display only the OrderId column and the calculated TotalSales column.
Which code segment should you use?
To answer, type the correct code in the answer area.
