Q48. You generate a daily report according to the following query: 

You need to improve the performance of the query. 

What should you do? 

A. Drop the UDF and rewrite the report query as follows: 

WITH cte(CustomerID, LastOrderDate) AS ( 

SELECT CustomerID, MAX(OrderDate) AS [LastOrderDate] 

FROM Sales.SalesOrder 

GROUP BY CustomerID 

) 

SELECT c.CustomerName 

FROM cte 

INNER JOIN Sales.Customer c 

ON cte.CustomerID = c.CustomerID 

WHERE cte.LastOrderDate < DATEADD(DAY, -90, GETDATE()) 

B. Drop the UDF and rewrite the report query as follows: 

SELECT c.CustomerName 

FROM Sales.Customer c 

WHERE NOT EXISTS ( 

SELECT s.OrderDate 

FROM Sales.SalesOrder 

WHERE s.OrderDate > DATEADD(DAY, -90, GETDATE()) 

AND s.CustomerID = c.CustomerID) 

C. Drop the UDF and rewrite the report query as follows:

CREATE FUNCTION Sales.ufnGetRecentOrders(@CustomerID int, @MaxAge datetime)
