Question 1:

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while

others might not have a correct solution.

After you answer a question in this section. You will NOT be able to return to it. As a result, these questions will not appear in the review screen.

You create a table named Products by running the following Transact-SQL statement:

You have the following stored procedure:

You need to modify the stored procedure to meet the following new requirements:

Insert product records as a single unit of work.

Return error number 51000 when a product fails to insert into the database.

If a product record insert operation fails, the product information must not be permanently written to the database.

Solution: You run the following Transact-SQL statement: Does the solution meet the goal?

A. Yes

B. No

Correct Answer: B

A transaction is correctly defined for the INSERT INTO ..VALUES statement, and if there is an error in the transaction it will be caught ant he transaction will be rolled back. However, error number 51000 will not be returned, as it is only used

in an IF @ERROR = 51000 statement.

Note: @@TRANCOUNT returns the number of BEGIN TRANSACTION statements that have occurred on the current connection.

Question 2:

Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.

You create a table by running the following Transact-SQL statement:

You need to develop a query that meets the following requirements:

Output data by using a tree-like structure.

Allow mixed content types.

Use custom metadata attributes.

Which Transact-SQL statement should you run?

A. B. C. D. E. F. G. H.

Correct Answer: F

In a FOR XML clause, you specify one of these modes: RAW, AUTO, EXPLICIT, and PATH.

The EXPLICIT mode allows more control over the shape of the XML. You can mix attributes and elements at will in deciding the shape of the XML. It requires a specific format for the resulting rowset that is generated because of query execution. This row set format is then mapped into XML shape. The power of EXPLICIT mode is to mix attributes and elements at will, create wrappers and nested complex properties, create space-separated values (for example, OrderID attribute may have a list of order ID values), and mixed contents.

The PATH mode together with the nested FOR XML query capability provides the flexibility of the EXPLICIT mode in a simpler manner.

Correct Answer: C

Question 9:

DRAG DROP

You need to create a stored procedure that meets the following requirements:

Produces a warning if the credit limit parameter is greater than 7,000

Propagates all unexpected errors to the calling process How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQL segments to the correct locations. Each Transact-SQL segments may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

Select and Place:

Correct Answer:

Box 1: THROW 51000, \’Warning: Credit limit isover 7,000!”,1

THROW raises an exception and transfers execution to a CATCH block of a TRY…CATCH construct in SQL Server.

THROW syntax:

THROW [ { error_number | @local_variable },

{ message | @local_variable },

{ state | @local_variable } ]

[ ; ]

Box2: RAISERROR (@ErrorMessage, 16,1)

RAISERROR generates an error message and initiates error processing for the session. RAISERROR can either reference a user-defined message stored in the sys.messages catalog view or build a message dynamically. The message is

returned as a server error message to the calling application or to an associated CATCH block of a TRY…CATCH construct. New applications should use THROW instead. Severity levels from 0 through 18 can be specified by any user.

Severity levels from 19through 25 can only be specified by members of the sysadmin fixed server role or users with ALTER TRACE permissions. For severity levels from 19 through 25, the WITH LOG option is required.

On Severity level 16. Using THROW to raise an exception

The following example shows how to use the THROW statement to raise an exception.

Transact-SQL

THROW 51000, \’The record does not exist.\’, 1;

Here is the result set.

Msg 51000, Level 16, State 1, Line 1

The record does not exist.

Note: RAISERROR syntax:

RAISERROR( { msg_id | msg_str | @local_variable }

{ ,severity ,state }

[ ,argument [ ,…n ] ] )

[ WITH option [ ,…n ] ]

Note: The ERROR_MESSAGE function returns the message text of the error that caused the CATCH block of a TRY…CATCH construct to be run.

Question 10:

DRAG DROP

Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is

exactly the same in each question on this series.

You have a database that tracks orders and deliveries for customers in North America. System versioning is enabled for all tables. The database contains the Sales.Customers, Application.Cities, and Sales.CustomerCategories tables.

Details for the Sales.Customers table are shown in the following table:

Details for the Application.Cities table are shown in the following table:

Details for the Sales.CustomerCategories table are shown in the following table:

The marketing department is performing an analysis of how discount affect credit limits. They need to know the average credit limit per standard discount percentage for customers whose standard discount percentage is between zero and four.

You need to create a query that returns the data for the analysis.

How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQL segments to the correct locations. Each Transact-SQL segments may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

Select and Place:

Correct Answer:

Box 1: 0, 1, 2, 3, 4

Pivot example:

— Pivot table with one rowand five columns

SELECT \’AverageCost\’ AS Cost_Sorted_By_Production_Days,

[0], [1], [2], [3], [4]

FROM

(SELECT DaysToManufacture, StandardCost

FROM Production.Product) AS SourceTable

PIVOT

(

AVG(StandardCost)

FOR DaysToManufacture IN ([0], [1], [2], [3], [4])

) AS PivotTable;

Box 2: [CreditLimit]

Box 3: PIVOT

You can use the PIVOT and UNPIVOT relational operators to change a table-valued expression into another table. PIVOT rotates a table-valued expression by turning the unique values from one column in the expression into multiple

columns in the output, and performs aggregations where they are required on any remaining column values that are wanted in the final output.

Box 4: 0, 1, 2, 3, 4

The IN clause determines whether a specified value matches any value in a subquery or a list.

Syntax: test_expression [ NOT ] IN ( subquery | expression [ ,…n ] )

Where expression[ ,… n ] is a list of expressions to test for a match. All expressions must be of the same type as test_expression.
