You develop a Microsoft SQL Server 2012 server database that supports an application. The application contains a table that has the following definition:
CREATE TABLE Inventory
(ItemID int NOT NULL PRIMARY KEY,
ItemsInStore int NOT NULL,
ItemsInWarehouse int NOT NULL)
You need to create a computed column that returns the sum total of the ItemsInStore and ItemsInWarehouse values for each row.
Which Transact-SQL statement should you use?
A. ALTER TABLE Inventory
ADD TotalItems AS ItemsInStore + ItemsInWarehouse
B. ALTER TABLE Inventory
ADD ItemsInStore – ItemsInWarehouse = TotalItemss
C. ALTER TABLE Inventory
ADD TotalItems = ItemsInStore + ItemsInWarehouse
D. ALTER TABLE Inventory
ADD TotalItems AS SUM(ItemsInStore, ItemslnWarehouse);
