Microsoft Transition Your MCTS on SQL Server 2008 to MCSA: SQL Server 2012, Part 1 認定 70-457 試験問題:

1. You use Microsoft SQL Server 2012 to develop a database application. Your application sends data to an NVARCHAR(MAX) variable named @var. You need to write a Transact-SQL statement that will find out the success of a cast to a decimal (36,9). Which code segment should you use?select

A) BEGIN TRY
SELECT convert(decimal(36,9), @var) AS Value, 'True' AS BadCast
END TRY
BEGIN CATCH
SELECT convert(decimal(36,9), @var) AS Value, 'False' AS BadCast
END CATCH
B) SELECT
CASE
WHEN convert(decimal(36,9), @var) IS NULL
THEN 'True'
ELSE 'False'
END
AS BadCast
C) SELECT
IIF(TRY_PARSE(@var AS decimal(36,9)) IS NULL, 'True', 'False')
AS BadCast
D) TRY( SELECT convert(decimal(36,9), @var) SELECT 'True' AS BadCast
)
CATCH(
SELECT 'False' AS BadCast
)

2. You have a database that contains the tables as shown in the exhibit. (Click the Exhibit button.)

You need to create a query that returns a list of products from Sales.ProductCatalog. The solution must meet the following requirements:
UnitPrice must be returned in descending order.
The query must use two-part names to reference the table.
The query must use the RANK function to calculate the results.
The query must return the ranking of rows in a column named PriceRank.
The list must display the columns in the order that they are defined in the table.
PriceRank must appear last.
Which code segment should you use?
To answer, type the correct code in the answer area.

A) SELECT ProductCatalog.CatID, ProductCatalog.CatName, ProductCatalog. ProductID, ProductCatalog.ProdName, ProductCatalog.UnitPrice, RANK() OVER (ORDER BY ProductCatalog.UnitPrice DESC) AS PriceRank FROM Sales.ProductCatalog ORDER BY ProductCatalog.UnitPrice DESC
B) SELECT ProductCatalog.CatID, ProductCatalog.CatName, ProductCatalog. ProductID, ProductCatalog.ProdName, ProductCatalog.UnitPrice, RANK() OVER (PARTITION BY ProductCatalog.UnitPrice ORDER BY ProductCatalog. UnitPrice DESC) AS PriceRank FROM Sales.ProductCatalog ORDER BY ProductCatalog.UnitPrice DESC

3. You have a database that contains the tables shown in the exhibit. (Click the Exhibit button).

You need to create a query for a report. The query must meet the following requirements:
NOT use object delimiters.
Return the most recent orders first.
Use the first initial of the table as an alias.
Return the most recent order date for each customer.
Retrieve the last name of the person who placed the order.
Return the order date in a column named MostRecentOrderDate that appears as the last column in the report.
The solution must support the ANSI SQL-99 standard.
Which code segment should you use?
To answer, type the correct code in the answer area.

A) SELECT LastName, O.OrderDate AS MostRecentOrderDate FROM Customers AS C INNER JOIN Orders AS O ON CustomerID = O.CustomerID ORDER BY O.OrderDate DESC
B) select C.Lastname, P.MostRecentOrderDate from customers AS C inner join ( select customID, MostRecentOrderDate=max(orderDate) from orders group by customID
)P
on C.customerID=P.CustomerID
order by P.MostRecentOrderDate desc
C) SELECT c.CustomerID --optional c.LastName, max(o.OrderDate) 'MostRecentOrderDate' FROM Customer c LEFT OUTER JOIN Orders o ON o.CustomerID = c.CustomerID GROUP BY c.CustomerID, c.LastName ORDER BY 3 DESC

4. You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area network (SAN). The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D).
A transaction log of 10 GB is located on a dedicated LUN (drive E).
Drive D has 1 terabyte of free disk space.
Drive E has 5 GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between
09:00
hours and 17:00 hours. Five percent of the existing data is modified each day. The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database. These data load operations must occur in the minimum amount of time. A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours. You need to ensure that your backup will continue if any invalid checksum is encountered. Which backup option should you use?

A) NORECOVERY
B) CONTINUE_AFTER_ERROR
C) Differential
D) SKIP
E) STANDBY
F) NO_CHECKSUM
G) DBO_ONLY
H) COPY_ONLY
I) Transaction log
J) RESTART
K) FULL
L) SIMPLE
M) BULK_LOGGED
N) CHECKSUM

5. You administer a Microsoft SQL Server 2012 server that has a database named Contoso. The Contoso database has a table named EmployeeSalary in a schema named HumanResources.
