Q18. You develop a Microsoft SQL Server 2012 database. The database is used by two web 

applications that access a table named Products. 

You want to create an object that will prevent the applications from accessing the table directly while still providing access to the required data. 

You need to ensure that the following requirements are met: 

. Future modifications to the table definition will not affect the applications' ability to access data. . The new object can accommodate data retrieval and data modification. 

You need to achieve this goal by using the minimum amount of changes to the applications. 

What should you create for each application? 

A. Synonyms 

B. Common table expressions 

C. Views 

D. Temporary tables 

Answer: C 

Q19. 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: D 

Q20. CORRECT TEXT

Use one-part names to reference columns. 

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.

You write the following Transact-SQL query: 

You discover that the performance of the query is slow. Analysis of the query plan shows table scans where the estimated rows do not match the actual rows for SalesOrderHeader by using an unexpected index on SalesOrderDetail.
