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

SELECT JobCandidateID, Resume.value('declare namespace

ns="http://schemas.microsoft.com/sqlserver/2004/07/adventure-works/Resume";

(/ns:Resume/ns:Name/ns:Name.First)[1]','nvarchar(20)') AS [First Name],

Resume.value('declare namespace

(/ns:Resume/ns:Name/ns:Name.Last)[1]','nvarchar(20)') AS [Last Name], Resume.value('declare namespace

Trang 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 ('

http://schemas.microsoft.com/sqlserver/2004/07/adventure-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 ('

http://schemas.microsoft.com/sqlserver/2004/07/adventure-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)

Chapter 6

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)
