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: 

SELECT DISTINCT c.CustomerName 

FROM Sales.Customer c 

INNER JOIN Sales.SalesOrder s 

ON c.CustomerID = s.CustomerID

D. Rewrite the report query as follows: 

SELECT c.CustomerName 

FROM Sales.Customer c 

WHERE NOT EXISTS (SELECT OrderDate FROM 

Sales.ufnGetRecentOrders(c.CustomerID, 90)) 

Rewrite the UDF as follows: 

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

RETURNS TABLE AS RETURN ( 

SELECT OrderDate 

FROM Sales.SalesOrder 

WHERE s.CustomerID = @CustomerID 

AND s.OrderDate > DATEADD(DAY, -@MaxAge, GETDATE())
