Q1. You develop three Microsoft SQL Server 2012 databases named Database1, Database2, and Database3.
You have permissions on both Database1 and Database2. You plan to write and deploy a stored procedure named dbo.usp_InsertEvent in Database3. dbo.usp_InsertEvent must execute other stored procedures in the other databases.
You need to ensure that callers that do not have permissions on Database1 or Database2 can execute the stored procedure.
Which Transact-SQL statement should you use?
A. USE Database2
B. EXECUTE AS OWNER
C. USE Database1
D. EXECUTE AS CALLER
Answer: B
Q2. CORRECT TEXT
You have a database that contains the tables as shown below:
You have a stored procedure named Procedure1. Procedure1 retrieves all order ids after a specific date. The rows for Procedure1 are not sorted. Procedure1 has a single parameter named Parameter1. Parameter1 uses the varchar type and is configured to pass the specific date to Procedure1. A database administrator discovers that OrderDate is not being compared correctly to Parameter1 after the data type of the column is changed to datetime. You need to update the SELECT statement to meet the following requirements:
The code must NOT use aliases.
The code must NOT use object delimiters.
The objects called in Procedure1 must be able to be resolved by all users.
OrderDate must be compared to Parameter1 after the data type of Parameter1 is
changed to datetime.
Which SELECT statement should you use?

Q3. You are writing a set of queries against a FILESTREAM-enabled database.
You create a stored procedure that will update multiple tables within a transaction.

transaction is terminated and rolled back.
Which Transact-SQL statement should you include at the beginning of the stored
procedure?
A. SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
B. SET XACT_ABORT OFF
C. SET TRANSACTION ISOLATION LEVEL SNAPSHOT
D. SET IMPLICIT_TRANSACTIONS ON

Q4. 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
Q5. Your database contains two tables named DomesticSalesOrders and InternationalSalesOrders. Both tables contain more than 100 million rows. Each table has a Primary Key column named SalesOrderId. The data in the two tables is distinct from one another.
Business users want a report that includes aggregate information about the total number of global sales and total sales amounts.
You need to ensure that your query executes in the minimum possible time.
Which query should you use?
A. SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM ( SELECT SalesOrderId, SalesAmount FROM DomesticSalesOrders UNION ALL SELECT SalesOrderId, SalesAmount FROM InternationalSalesOrders ) AS p
B. SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM ( SELECT SalesOrderId, SalesAmount FROM DomesticSalesOrders UNION SELECT SalesOrderId, SalesAmount FROM InternationalSalesOrders ) AS p
C. SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM DomesticSalesOrders UNION SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM InternationalSalesOrders
D. SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM DomesticSalesOrders UNION ALL SELECT COUNT(*) AS NumberOfSales, SUM(SalesAmount) AS TotalSalesAmount FROM InternationalSalesOrders
Answer: A
Q6. You use Microsoft SQL Server 2012 to develop a database application.
You create a stored procedure named dbo.ModifyData that can modify rows.
You need to ensure that when the transaction fails, dbo.ModifyData meets the following requirements:
. Does not return an error
. Closes all opened transactions
Which Transact-SQL statement should you use?
A. BEGIN TRANSACTION BEGIN TRY EXEC dbo.ModifyData COMMIT TRANSACTION END TRY BEGIN CATCH IF @@ TRANCOUNT = 0 ROLLBACK TRANSACTION; END CATCH
B. BEGIN TRANSACTION BEGIN TRY EXEC dbo.ModifyData COMMIT TRANSACTION END TRY BEGIN CATCH IF @@ERROR != 0 ROLLBACK TRANSACTION; THROW; END CATCH
C. BEGIN TRANSACTION BEGIN TRY EXEC dbo.ModifyData
COMMIT TRANSACTION END TRY BEGIN CATCH IF @@TRANCOUNT = 0 ROLLBACK TRANSACTION; THROW; END CATCH
D. BEGIN TRANSACTION BEGIN TRY EXEC dbo.ModifyData COMMIT TRANSACTION END TRY BEGIN CATCH IF @@ERROR != 0 ROLLBACK TRANSACTION; END CATCH
Answer: D
Q7. DRAG DROP
You develop a database application for a university. You need to create a view that will be indexed that meets the following requirements:
. Displays the details of only students from Canada.

Q8. Your database contains tables named Products and ProductsPriceLog. The Products table contains columns named ProductCode and Price. The ProductsPriceLog table contains columns named ProductCode, OldPrice, and NewPrice.
The ProductsPriceLog table stores the previous price in the OldPrice column and the new price in the NewPrice column.
You need to increase the values in the Price column of all products in the Products table by 5 percent. You also need to log the changes to the ProductsPriceLog table.
Which Transact-SQL query should you use?
A. UPDATE Products SET Price = Price * 1.05
OUTPUT inserted.ProductCode, deleted.Price, inserted.Price
INTO ProductsPriceLog(ProductCode, OldPrice, NewPrice)
B. UPDATE Products SET Price = Price * 1.05
OUTPUT inserted.ProductCode, inserted.Price, deleted.Price
INTO ProductsPriceLog(ProductCode, OldPrice, NewPrice)
C. UPDATE Products SET Price = Price * 1.05
OUTPUT inserted.ProductCode, deleted.Price, inserted.Price *
INTO ProductsPriceLog(ProductCode, OldPrice, NewPrice)
D. UPDATE Products SET Price = Price * 1.05
INSERT INTO ProductsPriceLog (ProductCode, CldPnce, NewPrice;
SELECT ProductCode, Price, Price * 1.05 FROM Products
Answer: A
