Q1. You are a database developer of a Microsoft SQL Server 2012 database. 

You are designing a table that will store Customer data from different sources. The table will include a column that contains the CustomerID from the source system and a column that contains the SourceID. 

A sample of this data is as shown in the following table. 

You need to ensure that the table has no duplicate CustomerID within a SourceID. You also need to ensure that the data in the table is in the order of SourceID and then CustomerID. 

Which Transact- SQL statement should you use? 

A. CREATE TABLE Customer 

(SourceID int NOT NULL IDENTITY, 

CustomerID int NOT NULL IDENTITY, 

CustomerName varchar(255) NOT NULL); 

B. CREATE TABLE Customer 

(SourceID int NOT NULL, 

CustomerID int NOT NULL PRIMARY KEY CLUSTERED, 

CustomerName varchar(255) NOT NULL); 

C. CREATE TABLE Customer 

(SourceID int NOT NULL PRIMARY KEY CLUSTERED, 

CustomerID int NOT NULL UNIQUE, 

CustomerName varchar(255) NOT NULL); 

D. CREATE TABLE Customer 

(SourceID int NOT NULL, 

CustomerID int NOT NULL, 

CustomerName varchar(255) NOT NULL, 

CONSTRAINT PK_Customer PRIMARY KEY CLUSTERED 

(SourceID, CustomerID));

Q2. 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 

existing applications. 

What should you create for each application? 

A. views 

B. table partitions 

C. table-valued functions 

D. stored procedures

A. SET XACT_ABORT ON 

B. SET ARITHABORT ON 

C. TRY 

D. BEGIN 

E. SET ARITHABORT OFF

Q5. 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: 

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())

Q9. 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

Q10. You develop a Microsoft SQL Server 2012 server database that supports an application. 

The application contains a table that has the following definition: 

CREATE TABLE Inventory ( 

ItemID int NOT NULL PRIMARY KEY, 

ItemsInStore int NOT NULL, 

ItemsInWarehouse int NOT NULL) 

You need to create a computed column that returns the sum total of the ItemsInStore and ItemsInWarehouse values for each row. 

The new column is expected to be queried heavily, and you need to be able to index the column. Which Transact-SQL statement should you use? 

A. ALTER TABLE Inventory 

ADD TotalItems AS ItemslnStore + ItemsInWarehouse 

B. ALTER TABLE Inventory 

ADD TotalItems AS ItemsInStore + ItemsInWarehouse PERSISTED 

C. ALTER TABLE Inventory 

ADD TotalItems AS SUM(ItemsInStore, ItemsInWarehouse) PERSISTED 

D. ALTER TABLE Inventory 

ADD TotalItems AS SUM(ItemsInStore, ItemsInWarehouse)
