QUESTION 1
You have a database that contains the following tables: 
You need to write a query that returns a list of all customers who have not placed orders. Which Transact-SQL
statement should you run?
A. SELECT c.custid FROM Sales.Customers c INNER JOIN Sales.Order oON c.custid = o.custid
B. SELECT custid FROM Sales.Customers INTERSECTSELECT custid FROM Sales.Orders
C. SELECTc.custid FROM Sales.Customers c LEFT OUTER Sales.Order oON c.custid = o.custid
D. SELECT c.custid FROM Sales.Customers c LEFT OUTER JOIN Sales.Order oON c.custid = o.custid WHERE
orderid IS NULL
E. SELECT custid FROM Sales.Customers UNION ALL SELECT custid FROM Sales.Orders
F. SELECT custid FROM Sales.Customers UNION SELECT custid FROM Sales.Orders
G. SELECT c.custid FROM Sales.Customers c RIGHT OUTER JOIN Sales.Orders o ON c.custid = o.custid
Correct Answer: D
Inner joins return rows only when there is at least one row from both tables that matches the join condition. Inner joins
eliminate the rows that do not match with a row from the other table. Outer joins, however, return all rows from at least
one of the tables or views mentioned in the FROM clause, as long as those rows meet any WHERE or HAVING search
conditions. All rows are retrieved from the left table referenced with a left outer join, and all rows from the right table
referenced in a right outer join. All rows from both tables are returned in a full outer join.

QUESTION 2
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:
You need to create a query that meets the following requirements:
For customers that are not on a credit hold, return the CustomerID and the latest recorded population for the delivery
city that is associated with the customer.
For customers that are on a credit hold, return the CustomerID and the latest recorded population for the postal city that
is associated with the customer.
Which two Transact-SQL queries will achieve the goal? Each correct answer presents a complete solution.
A. B. C. D.
Correct Answer: A
Using Cross Joins
A cross join that does not have a WHERE clause produces the Cartesian product of the tables involved in the join. The
size of a Cartesian product result set is the number of rows in the first table multiplied by the number of rows in the
second table.
However, if a WHERE clause is added, the cross join behaves as an inner join.
B: You can use the IIF in the ON-statement.
IIF returns one of two values, depending on whether the Boolean expression evaluates to true or false in SQL Server.

QUESTION 3
SIMULATION
You have a database that contains the following tables.
You need to create a query that returns each complaint, the names of the employees handling the complaint, and the
notes on each interaction. The Complaint field must be displayed first, followed by the employee’s name and the notes.
Complaints must be returned even if no interaction has occurred. Construct the query using the following guidelines:
Use two-part column names.
Use one-part table names.
Use the first letter of the table name as its alias.
Do not Transact-SQL functions.
Do not use implicit joins.
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.
1 SELECT c.Complaint, e.Name, i.Notes 2 FROM Complaints c 3 JOIN __________________ 4 JOIN
__________________
Correct Answer:
1 SELECT c.Complaint, e.Name, i.Notes
2 FROM Complaints c
3 JOIN Interactions i ON c.ComplaintID = i.ComplaintID
4 JOIN Employees e ON i.EmployeeID = E.EmployeeID
QUESTION 4
You are building a stored procedure that will update data in a table named Table1 by using a complex query as the data
source.
You need to ensure that the SELECT statement in the stored procedure meets the following requirements:
Data being processed must be usable in several statements in the stored procedure.
Data being processed must contain statistics.
What should you do?
A. Update Table1 by using a common table expression (CTE).
B. Insert the data into a temporary table, and then update Table1 from the temporary table.
C. Place the SELECT statement in a derived table, and then update Table1 by using a JOIN to the derived table.
D. Insert the data into a table variable, and then update Table1 from the table variable.
Correct Answer: B
Temp Tables… Are real materialized tables that exist in tempdb Have dedicated stats generated by the engine Can be
indexed Can have constraints Persist for the life of the current CONNECTION Can be referenced by other queries or
subproce Incorrect Answers:
A: CTEs do not have dedicated stats. They rely on stats on the underlying objects
C: Unlike a derived table, a CTE can be self-referencing and can be referenced multiple times in the same query.

QUESTION 5
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.

QUESTION 10
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 is over 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.
