Q2. You create a table that has the StudentCode, SubjectCode, and Marks columns to record mid-year marks for students. The table has marks obtained by 50 students for various subjects. 

You need to ensure that the top half of the students arranged by their average marks must be given a rank of 1 and the remaining students must be given a rank of 2.

A. SELECT StudentCode as Code, 

RANK() OVER (ORDER BY AVG (Marks) DESC) AS Value 

FROM StudentMarks 

GROUP BY StudentCode 

B. SELECT Id, Name, Marks, 

DENSE_RANK() OVER (ORDER BY Marks DESC) AS Rank 

FROM StudentMarks 

C. SELECT StudentCode as Code, 

DENSE_RANK() OVER (ORDER BY AVG (Marks) DESC) AS Value 

FROM StudentMarks 

GROUP BY StudentCode 

D. SELECT StudentCode as Code, 

NTILE (2) OVER (ORDER BY AVG (Marks) DESC) AS Value 

FROM StudentMarks 

GROUP BY StudentCode 

E. SELECT StudentCode AS Code,Marks AS Value FROM ( 

SELECT StudentCode, Marks AS Marks, 

RANK() OVER (PARTITION BY SubjectCode ORDER BY Marks ASC) AS Rank 

FROM StudentMarks) tmp 

WHERE Rank = 1 

F. SELECT StudentCode AS Code,Marks AS Value FROM ( 

SELECT StudentCode, Marks AS Marks, 

RANK() OVER (PARTITION BY SubjectCode ORDER BY Marks DESC) AS Rank 

FROM StudentMarks) tmp 

WHERE Rank = 1 

G. SELECT StudentCode AS Code,Marks AS Value FROM ( SELECT StudentCode, Marks AS Marks, RANK () OVER (PARTITION BY StudentCode ORDER BY Marks ASC) AS Rank FROM StudentMarks) tmp WHERE Rank = 1 

H. SELECT StudentCode AS Code,Marks AS Value FROM ( SELECT StudentCode, Marks AS Marks, RANXO OVER (PARTITION BY StudentCode ORDER BY Marks DESC) AS Rank FROM StudentMarks) tmp WHERE Rank = 1 

Answer: D

Q3. You are a database developer for an application hosted on a Microsoft SQL Server 2012 server. The database contains two tables that have the following definitions: 

Global customers place orders from several countries. You need to view the country from which each customer has placed the most orders. 

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 

B. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM (SELECT c.CustomerID, c.CustomerName, o.ShippingCountry, 

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

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

D. SELECT c.CustomerID, c.CustomerName, o.ShippingCountry FROM Customer c INNER JOIN (SELECT CustomerID, ShippingCountry, COUNT(OrderAmount) DESC) AS OrderAmount FROM Orders GROUP BY CustomerID, ShippingCountry) AS o ON c.CustomerID = o.CustomerID ORDER BY OrderAmount DESC 

Answer: A
