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); 

Answer:

Q62. Your database contains a table named SalesOrders. The table includes a DATETIME column named OrderTime that stores the date and time each order is placed. There is a non-clustered index on the OrderTime column. 

The business team wants a report that displays the total number of orders placed on the current day. 

You need to write a query that will return the correct results in the most efficient manner. 

Which Transact-SQL query should you use? 

A. SELECT COUNT(*) FROM SalesOrders 

WHERE OrderTime = CONVERT(DATE, GETDATE()) 

B. SELECT COUNT(*) FROM SalesOrders 

WHERE OrderTime = GETDATE() 

C. SELECT COUNT(*) FROM SalesOrders 

WHERE CONVERT(VARCHAR, OrderTime, 112) = CONVERT(VARCHAR, GETDATE(I, 

112)) 

D. SELECT COUNT(*) FROM SalesOrders 

WHERE OrderTime >= CONVERT(DATE, GETDATE()) 

AND OrderTime < DATEADD(DAY, 1, CONVERT(DATE, GETDATE())) 

Answer:

Q63. You administer a Microsoft SQL Server 2012 database named ContosoDb. Tables are defined as shown in the exhibit. (Click the Exhibit button.)

<row OrderId="2" OrderDate="2001-01-01T00:00:00" Amount="4300.00" Name="Customer 

A" Country="Australia" /> 

Which Transact-SQL query should you use? 

A. SELECT OrderId, OrderDate, Amount, Name, Country FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML RAW 

B. SELECT OrderId, OrderDate, Amount, Name, Country FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML RAW, ELEMENTS 

C. SELECT OrderId, OrderDate, Amount, Name, Country FROM Orders INNER JOIN Customers ON Orders.CustomerId = Customers.CustomerId WHERE Customers.CustomerId = 1 FOR XML AUTO 

D. SELECT OrderId, OrderDate, Amount, Name, Country FROM Orders INNER JOIN Customers ON Orders.CustomerId – Customers.CustomerId WHERE Customers.CustomerId= 1 FOR XML AUTO, ELEMENTS 

E. SELECT Name, Country, OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId- 1 FOR XML AUTO 

F. SELECT Name, Country, Orderld, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId= 1 FOR XML AUTO, ELEMENTS 

G. SELECT Name AS '@Name', Country AS '@Country', OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId= 1 FOR XML PATH ('Customers') 

H. SELECT Name AS 'Customers/Name', Country AS 'Customers/Country', OrderId, OrderDate, Amount FROM Orders INNER JOIN Customers ON Orders.CustomerId= Customers.CustomerId WHERE Customers.CustomerId= 1 FOR XML PATH ('Customers')
