You have a database that contains the tables shown in the exhibit. (Click the Exhibit button.)
You deploy a new server that has SQL Server 2012 installed. You need to create a table
named
Sales.OrderDetails on the new server. Sales.OrderDetails must meet the following
requirements:
• Write the results to a disk.
• Contain a new column named LineItemTotal that stores the product of ListPrice and
Quantity for each row.
• The code must NOT use any object delimiters.
The solution must ensure that LineItemTotal is stored as the last column in the table. Which
code segment should you use?

One thing is strange in this question: “You have a database that contains the tables shown in the exhibit. ”
So the table Sales.OrderDetails already exist, so maybe is not correct just create, or drop before create, or alter…

But ‘you deploy a new server’ and ‘need to create a table named Sales.OrderDetails on the new server’. So there’s no need for dropping or altering.
