Question 1
You develop a Microsoft SQL Server 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?
ALTER TABLE Inventory
ADD TotalItems AS ItemsInStore + ItemsInWarehouse
ALTER TABLE Inventory
ADD ItemsInStore - ItemsInWarehouse = TotalItemss
ALTER TABLEInventory
ADD TotalItems = ItemsInStore + ItemsInWarehouse
ALTER TABLE Inventory
ADD TotalItems AS SUM(ItemsInStore, ItemsInWarehouse);
