Question 4:

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 datetime datetype defines a date that is combined with a time of day with fractional seconds that is based on a 24-hour clock. The DATEFROMPARTS function returns a date value for the specified year, month, and day.

Question 5:

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 have a database that stores sales and order information.

Users must be able to extract information from the tables on an ad hoc basis. They must also be able to reference the extracted information as a single table.

You need to implement a solution that allows users to retrieve the data required, based on variables defined at the time of the query.

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

H. the TRY_CONVERT function

Correct Answer: C

User-defined functions that return a table data type can be powerful alternatives to views. These functions are referred to as table-valued functions. A table-valued user-defined function can be used where table or view expressions are

allowed in Transact-SQL queries. While views are limited to a single SELECT statement, user-defined functions can contain additional statements that allow more powerful logic than is possible in views.

A table-valued user-defined function can also replace stored procedures that return a single result set.

You are developing a report that displays the following values and column headers in the order listed below:

average price of a product named Average

the smallest number of products in stock named LowestNumber

the highest product price named HighestPrice

Use the Check Syntax button to verify your work. Any syntax or spelling errors will be reported by line and character position. You may check syntax as many times as needed.

A. Check the answer in explanation.

Correct Answer: A

Question 8:

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 9:

SIMULATION

You work for an organization that monitors seismic activity around volcanos. You have a table named GroundSensors. The table stored data collected from seismic sensors. It includes the columns describes in the following table:

The database also contains a scalar value function named NearestMountain that returns the name of the mountain that is nearest to the sensor.

You need to create a query that shows the average of the normalized readings from the sensors for each mountain. The query must meet the following requirements:

Include the average normalized readings and nearest mountain name.

Exclude sensors for which no normalized reading exists.

Exclude those sensors with value of zero for tremor.

Construct the query using the following guidelines:

Use one part names to reference tables, columns and functions.

Do not use parentheses unless required.

Do not use aliases for column names and table names.

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

SELECT Average(NormalizedReading), NearestMountain(SensorID)

FROM GroundSensors

GROUP BY NearestMountain(SensorID)

WHERE TREMOR IS NOT 0 AND NormalizedReading IS NOT NULL

GROUP BY is a SELECT statement clause that divides the query result into groups of rows, usually for the purpose of performing one or more aggregations on each group. The SELECT statement returns one row per group. Reference: https://msdn.microsoft.com/en-us/library/ms177673.aspx

Question 10:

HOTSPOT

You have the following Transact-SQL query:

What type of functions are used in the query? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

Hot Area:

Correct Answer:

Box 1: Scalar

The return value of a function can either be a scalar (single) value or a table.

Box 2: Table-Valued

The APPLY operator allows you to invoke a table-valued function for each row returned by an outer table expression of a query. The table-valued function acts as the right input and the outer table expression acts as the left input. The right

input is evaluated for each row from the left input and the rows produced are combined for the final output. The list of columns produced by the APPLY operator is the set of columns in the left input followed by the list of columns returned by

the right input.
