A store in AdventureWorks is treated like a customer. Therefore, you need to first
create a record in the customer table by storing the territory id and specifying the
customer type as 'S'. Then you need to add the store details in the Store table.
Solution
Generate the customerId for the new store by storing the details in the Customer table as
follows:
INSERT INTO Sales.Customer VALUES (7,'S', DEFAULT, DEFAULT)
Store the details of the new store in the Store table as follows:
INSERT INTO Sales.Store VALUES(29484, 'Car store', 285,
'<StoreSurvey
xmlns=" />works/StoreSurvey">
<AnnualSales>350000</AnnualSales>
<AnnualRevenue>35000</AnnualRevenue>

Exercise 3
The address of a vendor, Comfort Road Bicycles, has changed. You need to update the
following data in the AdventureWorks database.
Address 4151 Olivera
City Atlanta
StateProvinceID 17
PostalCode 30308
Solution
To update the data, write the following statements in the Query Editor window of the
Microsoft SQL Server Management Studio window:
Update Purchasing.VendorAddress
set AddressID =
(Select AddressID from Person.Address Where AddressLine1 = '4151
Olivera'
AND City = 'Atlanta')
FROM Purchasing.VendorAddress va, Purchasing.Vendor v
WHERE va.VendorID = v.VendorID
AND v.Name = 'Comfort Road Bicycles'
Exercise 4
Delete all the records from the ProductBrand table. Ensure that you do not delete the
table.
Solution
To delete all the records, write the following statements in the Query Editor window of
the Microsoft SQL Server Management Studio window:
Truncate table ProductBrand

Exercise 5
The users of AdventureWorks need to publish the details of all the customers and their
address on the organizations website. To perform this task, you need to retrieve the data in
the XML format.
Solution
To retrieve the data in XML format, write the following statements in the Query Editor
window of the Microsoft SQL Server Management Studio window:
SELECT c.CustomerID, TerritoryID, AccountNumber, CustomerType,
AddressLine1, City,
StateProvinceID, PostalCode
FROM Sales.Customer c JOIN Sales.CustomerAddress ca
ON c.CustomerID = ca.CustomerID
JOIN Person.Address a
ON ca.AddressID = a.AddressID
FOR XML PATH('Customer')
Exercise 6
The management of AdventureWorks require a list displaying the skills of all the
candidates who have applied for a vacancy. The details of all the candidates are stored in
the XML format in the HumanResources.JobCandidate table.
Solution
To generate the list, write the following statement in the Query Editor window of the
Microsoft SQL Server Management Studio window:
SELECT JobCandidateID, Resume.value('declare namespace
ns=" />works/Resume";
(/ns:Resume/ns:Name/ns:Name.First)[1]','nvarchar(20)') AS [First
Name],
Resume.value('declare namespace
ns=" />works/Resume";
(/ns:Resume/ns:Name/ns:Name.Last)[1]','nvarchar(20)') AS [Last Name],

Resume.value('declare namespace
ns=" />works/Resume";
¤NIIT Instructor Inputs 9.7
(/ns:Resume/ns:Skills)[1]','nvarchar(max)') AS [Skills]
FROM HumanResources.JobCandidate
Exercise 7
The production of a bicycle at AdventureWorks involves a number of phases. In each
phase, the bicycle is moved to a different work center. The details of all the work centers
are stored in the Production.ProductModel table. Bicycles of different types go through
different set of work centres, depending on the components that need to be attached. The
management wants a list of all the types of bicycles that go through work center 10. How
will you generate this list?
Solution
To generate the list, write the following statement in the Query Editor window of the
Microsoft SQL Server Management Studio window:
WITH
XMLNAMESPACES ('
/>works/ProductModelManuInstructions' AS pd )
SELECT ProductModelID
FROM Production.ProductModel WHERE
Instructions.exist('/pd:root/pd:Location[@LocationID=10]' ) = 1
Exercise 8
There is a change in the production process of the bicycle with the product model id 7.
Due to this change, the bicycle will not be going to work centre 10. You need to update
this change in the database. How will you perform this task?
Solution
To update the changes, write the following statements in the Query Editor window of
the Microsoft SQL Server Management Studio window:
WITH
XMLNAMESPACES ('

/>works/ProductModelManuInstructions' AS pd )
UPDATE Production.ProductModel SET
Instructions.modify('delete (/pd:root/pd:Location)[1]' )
WHERE ProductModelID = 7

Exercise 1
The SalesOrderDetail and SalesOrderHeader tables store the details of the sales orders. To
generate a report displaying the sales order id and the total amount of all the products
purchased against an order, you are using the following query:
SELECT sd.SalesOrderID, sum(LineTotal) AS [Total Amount]
FROM Sales.SalesOrderDetail sd JOIN Sales.SalesOrderHeader sh
ON sd.SalesOrderID = sh.SalesOrderID
GROUP BY sd.SalesOrderID
The table contains a large amount of data. Create an appropriate index to optimize the
execution of this query.
Solution
To optimize the query performance, you need to create the clustered index on the
SalesOrderID attribute of the table SalesOrderHeader table as this column contains unique
and non-null values. To solve the problem, you need to execute the following statement:
CREATE NONCLUSTERED INDEX idxSalesOrderID
ON Sales.SalesOrderDetail (SalesOrderID)
Exercise 2
The Store table is often queried. The queries are based on the CustomerID attribute and
take long time to execute. Optimize the execution of the queries. In addition, ensure that
the CustomerID attribute does not contain duplicate values.
Solution
To optimize the execution of the queries, based on the CustomerID attribute of the Store
table, you need to create a unique nonclustered index on the CustomerID column. To
solve the problem, you need to execute the following statement:
CREATE UNIQUE NONCLUSTERED INDEX Idx_CustomerID

ON Sales.Store(CustomerID)

¤NIIT Instructor Inputs 9.9
Exercise 3
The SalesOrderDetail table is often queried. The queries are based on the
SalesOrderDetailID and SalesOrderID attributes. The execution of the queries takes a
long time. Optimize the execution of the queries.
Solution
You need to create the nonclustered index on the SalesOrderDetailID and SalesOrderID
attributes of the SalesOrderDetail table in order to speed up the query execution. To solve
the problem, you need to execute the following statement:
CREATE NONCLUSTERED INDEX Idx_SalesOrderId_SalesOrderDetailId
ON Sales.SalesOrderDetail(SalesOrderId, SalesOrderDetailId)
