Question 1:

You need to create an indexed view that requires logic statements to manipulate the data that the view displays. Which two database objects should you use? Each correct answer presents a complete solution.

A. a user-defined table-valued function

B. a CRL function

C. a stored procedure

D. a user-defined scalar function

Correct Answer: AC

You can create a database object inside an instance of SQL Server that is programmed in an assembly created in the Microsoft .NET Framework common language runtime (CLR). Database objects that can leverage the rich programming model provided by the common language runtime include aggregate functions, functions, stored procedures, triggers, and types.


Question 2:

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.

A database has two tables as shown in the following database diagram:

You need to list all provinces that have at least two large cities. A large city is defined as having a population of at least one million residents. The query must return the following columns: tblProvince.ProvinceId tblProvince.ProvinceName a derived column named LargeCityCount that presents the total count of large cities for the province

Solution: You run the following Transact-SQL statement:

Does the solution meet the goal?

A. Yes

B. No

Correct Answer: B

The SQL CROSS JOIN produces a result set which is the number of rowsin the first table multiplied by the number of rows in the second table if no WHERE clause is used along with CROSS JOIN. This kind of result is called as Cartesian

Product.

This is not what is required in this scenario.

Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question.

You have a table named Person that contains information about employees. Users are requesting a way to access specific columns from the Person table without specifying the Person table in the query statement. The columns that users can access will be determined when the query is running against the data. There are some records that are restricted, and a trigger will evaluate whether the request is attempting to access a restricted record.

You need to ensure that users can access the needed columns while minimizing storage on the database server.

What should you implement?

A. the COALESCE function

B. a view

C. a table-valued function

D. the TRY_PARSE function

E. a stored procedure

F. the ISNULL function

G. a scalar function

Question 6:

SIMULATION

You have a table named Cities that has the following two columns: CityID and CityName. The CityID column uses the int data type, and CityName uses nvarchar(max).

You have a table named RawSurvey. Each row includes an identifier for a question and the number of persons that responded to that question from each of four cities. The table contains the following representative data:

A reporting table named SurveyReport has the following columns: CityID, QuestionID, and RawCount, where RawCount is the value from the RawSurvey table.

You need to write a Transact-SQL query to meet the following requirements:

Retrieve data from the RawSurvey table in the format of the SurveyReport table.

The CityID must contain the CityID of the city that was surveyed.

The order of cities in all SELECT queries must match the order in the RawSurvey table.

The order of cities in all IN statements must match the order in the RawSurvey table.

Construct the query using the following guidelines:

Use one-part names to reference tables and columns, except where not possible.

ALL SELECT statements must specify columns.

Do not use column or table aliases, except those provided.

Do not surround object names with square brackets.

Part of the correct Transact-SQL has been provided in the answer area below. Enter the code in the answer area that resolves the problem and meets the stated goals or requirements. You can add code within the code that has been provided as well as below it.

Use the Check Syntax button to verify your work. Any syntax or spelling errors will be reported by line and character position.

Correct Answer: explanation

Please see explanation

1 SELECT Rawcount

2 from (select cityid,questioned,rawcount) AS t1

3 unpivot

4 (rawcount for questioned in (QuestionID)) AS t2

5 JOIN t2

6. ON t1.CityName = t2.cityName

UNPIVOT must be used to rotate columns of the Rawsurvey table into column values.

Question 7:

HOTSPOT

You need to develop a Transact-SQL statement that meets the following requirements:

The statement must return a custom error when there are problems updating a table.

The error number must be the value 50555.

The error severity level must be 14.

A Microsoft SQL Server alert must be triggered when the error condition occurs.

Which Transact-SQL segment should you use for each requirement? To answer, select the appropriate Transact-SQL segments in the answer area.

Hot Area:

Correct Answer:

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.

Note: RAISERROR syntax:

RAISERROR( { msg_id | msg_str | @local_variable }

{ ,severity ,state }

[ ,argument [ ,…n ] ] )

[ WITH option [ ,…n ] ]

The LOG option logs the error in the error log and the application log for the instance of the Microsoft SQL Server Database Engine.
