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 have a database that tracks orders and deliveries for customers in North America. The database contains the following tables:

Sales.Customers

Application.Cities

Sales.CustomerCategories

The company\’s development team is designing a customer directory application. The application must list customers by the area code of their phone number. The area code is defined as the first three characters of the phone number.

The main page of the application will be based on an indexed view that contains the area and phone number for all customers.

You need to return the area code from the PhoneNumber field.

Solution: You run the following Transact-SQL statement:

Does the solution meet the goal?

A. Yes

B. No

Correct Answer: B

As the result of the function will be used in an indexed view we should use schemabinding. References: https://sqlstudies.com/2014/08/06/schemabinding-what-why/


Question 2:

You need to create a table named MiscellaneousPayment that meets the following requirements:

Which Transact-SQL statement should you run?

A. B. C. D.

Correct Answer: D

Incorrect Answers:

A: For column Reason we must use nvarchar, not varchar, as multilingual values must be supported.

B: We cannot use INT for the Id column as new values must be automatically generated.

C: For column Reason we must use nvarchar, not varchar, as multilingual values must be supported.

Note: Nvarchar stores UNICODE data. If you have requirements to store UNICODE or multilingual data, nvarchar is the choice. Varchar stores ASCII data and should be your data type of choice for normal use.

Select and Place:

Correct Answer:

Box 1: SELECT CAST (NULL AS INT) AS ParentTaskID, etc.

This statement selects all tasks with task level 0.

The ParentTaskID could be null so we should use CAST (NULL AS INT) AS ParentTaskID.

Box 2: UNION

We should use UNION and not UNION ALL as we do not went duplicate rows.

UNION specifies that multiple result sets are to be combined and returned as a single result set.

Incorrect Answers:

Not UNION ALL: ALL incorporates all rows into the results. This includes duplicates. If not specified, duplicate rows are removed.

Box 3, Box 4, Box 5:

Question 9:

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.

The Task table includes the following columns:

You need to find all projects that have at least one task that took more than 50 hours to complete. You must also determine the average duration of the tasks that took more that took more than 50 hours to complete for each project.

How should you complete the Transact-SQL statement? To answer, drag the appropriate Transact-SQL segments to the correct locations. Each Transact-SQL segment 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.
