QUESTION 1
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.

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 thescenario is
exactly the same in each question in this series.
You are developing a database to track customer orders. The database contains the following tables: Sales.Customers,
Sales.Orders, and Sales.OrderLines. The following table describes the columns in Sales.Customers.
The following table describes the columns in Sales.OrderLines. 
You need to create a database object that calculates the total price of an order including the sales tax. The database
object must meet the following requirements:
Reduce the compilation cost of Transact-SQL code by caching the plans and reusing them for repeated execution.
Return a value.
Be callable from a SELECT statement.
How should you complete the Transact-SQL statements? To answer, select the appropriate Transact-SQL segments in
the answer area.
Hot Area: 
Box 1: FUNCTION
To be able to return a value we should use a scalar function.
CREATE FUNCTION creates a user-defined function in SQL Server and Azure SQL Database. The return value can
either be a scalar (single) value or a table.
Box 2: RETURNS decimal(18,2)
Use the same data format as used in the UnitPrice column.
Box 3: BEGIN
Transact-SQL Scalar Function Syntax include the BEGIN ..END construct.
CREATE [ OR ALTER ] FUNCTION [ schema_name. ] function_name
( [ { @parameter_name [ AS ][ type_schema_name. ] parameter_data_type
[ = default ] [ READONLY ] }

tables. Servers
You need to return all error log messages and the server where the error occurs most often. Which Transact-SQL
statement should you run? 
C. D.
Correct Answer: C
QUESTION 4
You need to create a database object that meets the following requirements:
accepts a product identifies as input
calculates the total quantity of a specific product, including quantity on hand and quantity on order
caches and reuses execution plan
returns a value
can be called from within a SELECT statement

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 in this series.
Start of repeated scenario
You have a database that contains the tables shown in the exhibit. (Click the Exhibit button.)
You review the Employee table and make the following observations: Every record has a value in the ManagerID except
for the Chief Executive Officer (CEO). The FirstName and MiddleName columns contain null values for some records.
The valid values for the Title column are Sales Representative manager, and CEO.
You review the SalesSummary table and make the following observations: The ProductCode column contains two parts:
The first five digits represent a product code, and the last seven digits represent the unit price. The unit price uses the
following pattern: ####.##. You observe that for many records, the unit price portion of the ProductCode column
contains values. The RegionCode column contains NULL for some records. Sales data is only recorded for sales
representatives.
You are developing a series of reports and procedures to support the business. Details for each report or procedure
follow.
Sales Summary report: This report aggregates data by year and quarter. The report must resemble the following table. 
Sales Manager report: This report lists each sales manager and the total sales amount for all employees that report to
the sales manager.
Sales by Region report: This report lists the total sales amount by employee and by region. The report must include the
following columns: EmployeeCode, MiddleName, LastName, RegionCode, and SalesAmount. If MiddleName is NULL,
FirstName must be displayed. If both FirstName and MiddleName have null values, the world Unknown must be
displayed/ If RegionCode is NULL, the word Unknown must be displayed.
Report1: This report joins data from SalesSummary with the Employee table and other tables. You plan to create an
object to support Report1. The object has the following requirements:
be joinable with the SELECT statement that supplies data for the report
can be used multiple times with the SELECT statement for the report
be usable only with the SELECT statement for the report
not be saved as a permanent object
Report2: This report joins data from SalesSummary with the Employee table and other tables. You plan to create an
object to support Report1. The object has the following requirements:
be joinable with the SELECT statement that supplies data for the report
can be used multiple times for this report and other reports
accept parameters
be saved as a permanent object
Sales Hierarchy report: This report aggregates rows, creates subtotal rows, and super-aggregates rows over the
SalesAmount column in a single result-set. The report uses SaleYear, SaleQuarter, and SaleMonth as a hierarchy. The
result set must not contain a grand total or cross-tabulation aggregate rows.
Current Price Stored Procedure: This stored procedure must return the unit price for a product when a product code is
supplied. The unit price must include a dollar sign at the beginning. In addition, the unit price must contain a comma
every three digits to the left of the decimal point, and must display two digits to the left of the decimal point. The stored
procedure must not throw errors, even if the product code contains invalid data.
End of Repeated Scenario
You need to create the query for the Sales Managers report.
Which four Transact-SQL segments should you use to develop the solution? To answer, move the appropriate Transact-
SQL segments from the list of Transact-SQL segments to the answer area and arrange them in the correct order.
Select and Place: 
From scenario: Sales Manager report: This report lists each sales manager and the total sales amount for all employees
that report to the sales manager.
Box 1:..WHERE Title=\\’Sales representative\\’
The valid values for the Title column are Sales Representative manager, and CEO.
First we define the CTE expression.
Note: A common table expression (CTE) can be thought of as a temporary result set that is defined within the execution
scope of a single SELECT, INSERT, UPDATE, DELETE, or CREATE VIEW statement. A CTE is similar to a derived
table in that it is not stored as an object and lasts only for the duration of the query. Unlike a derived table, a CTE can be
self-referencing and can be referenced multiple times in the same query.
Box 2:
Use the CTE expression one time.
Box 3: UNION
Box 4:
Use the CTE expression a second time.

B. No
Correct Answer: B
With X_ABORT ON the INSERT INTO statement and the transaction will be rolled back when an error is raised, it would
then not be possible to ROLLBACK it again in the IF XACT_STATE() O ROLLBACK TRANSACTION statement.
Note: A transaction is correctly defined for the INSERT INTO ..VALUES statement, and if there is an error in the
transaction it will be caughtant he transaction will be rolled back, finally an error 51000 will be raised.
Note: When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-time error, the entire transaction is
terminated and rolled back. XACT_STATE is a scalar function thatreports the user transaction state of a current running
request. XACT_STATE indicates whether the request has an active user transaction, and whether the transaction is
capable of being committed.
The states of XACT_STATE are:
0 There is no active user transaction for the current request.
1 The current request has an active user transaction. The request can perform any actions, including writing data and
committing the transaction.
2 The current request has an active user transaction, but an error hasoccurred that has caused the transaction to be
classified as an uncommittable transaction.

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 in this series.
You are developing a database to track customer orders. The database contains the following tables: Sales.Customers,
Sales.Orders, and Sales.OrderLines. The following table describes the columns in Sales.Customers.
The following table describes the columns in Sales.OrderLines.
You need to create a stored procedure that inserts data into the Customers table. The stored procedure must meet the
following requirements:
Data changes occur as a single unit of work.
Data modifications that are successful are committed and a value of 0 is returned.
Data modifications that are unsuccessful are rolled back. The exception severity level is set to 16 and a value of -1 is
returned.
The stored procedure uses a built-it scalar function to evaluate the current condition of data modifications.
The entire unit of work is terminated and rolled back if a run-time error occurs during execution of the stored procedure.
How should complete the stored procedure definition? To answer, drag the appropriate Transact-SQL segments to the
correct targets. 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.
NOTE: Each correct selection is worth one point.
Select and Place: 
Box 1: XACT_ABORT
XACT_ABORT specifies whether SQL Server automatically rolls back the current transaction when a Transact-SQL
statement raises a run-time error. When SET XACT_ABORT is ON, if a Transact-SQL statement raises a run-timeerror,
the
entire transaction is terminated and rolled back.
Box 2: COMMIT
Commit the transaction.
Box 3: XACT_STATE
Box 4: ROLLBACK
Rollback the transaction
Box 5: THROW
THROW raises an exception and the severity is set to 16.
Requirement: Data modifications that are unsuccessful are rolled back. The exception severity level is set to 16 and a
value of -1 is returned.

QUESTION 26
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 in this series.
You query a database that includes two tables: Project and Task. The Project table includes the following columns:
When running an operation, you updated a column named EndTime for several records in the Project table, but updates
to the corresponding task records in the Task table failed.
You need to synchronize the value of the EndTime column in the Task table with the value of the EndTime column in
the project table. The solution must meet the following requirements:
If the EndTime column has a value, make no changes to the record.
If the value of the EndTime column is null and the corresponding project record is marked as completed, update the
record with the project finish time.
Which four Transact-SQL segments should you use to develop the solution? To answer, move the appropriate Transact-
SQL segments from the list of Transact-SQL segments to the answer area and arrange them in the correct order.
Select and Place: 
Box 1: UPDATE T SET T.EndTime = P.EndTime
We are updating the EndTime column in the Task table.
Box 2: FROM Task AS T
Where are updating the task table.
Box 3:INNER JOIN Project AS P on T.ProjectID = P.ProjectID
We join with the Project table (on the ProjectID columnID column).
Box 4: WHERE P.EndTime is NOT NULL AND T.EndTime is NULL
We select the columns in the Task Table where the EndTime column in the Project table has a value (NOT NULL),but
where it is NULL in the Task Table.
