Which Transact-SQL query do you use? 

A. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c INNER JOIN (SELECT CustomerID, ShippingCountry, RANK() OVER (PARTITION BY CustomerID ORDER BY COUNT(OrderAmount) DESC) AS Rnk FROM Orders GROUP BY CustomerID, ShippingCountry) AS o ON c.CustomerID = o.CustomerID WHERE o.Rnk = 1

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 

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

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())
