  7. 7. Answer: AQUESTION 12 You are a database developer and you have many years experience in database development. Now you areemployed in a company which is named Loxgo. The company uses SQL Server 2008 and all the company datais stored in the SQL Server 2008 database. There is a table named dbo.Sellings in the database. The table contains thefollowing table definition: CREATE TABLE [dbo].[Selling]( [SellingID] [int] IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED, [OrderDate] [datetime] NOT NULL, [CustomerID] [int] NOT NULL, [SellingPersonID] [int] NULL, [CommentDate] [date] NULL); Since you notice that this query takes a long time to run, you start to examine the data. You find that only 2%of rows have comment dates and the SellingPersonID is null on 10% of the rows after the examination. So youhave to improve the query performance. You have to create an index which must save disk space when optimize thequery. Of the following index, which one should you choose?A. CREATE NONCLUSTERED INDEX idx2 ON dbo.Selling (CommentDate, SellingPersonID) INCLUDE (CustomerID)WHERE CommentDate IS NOT NULLB. CREATE NONCLUSTERED INDEX idx2ON dbo.Selling (CustomerID)INCLUDE (CommentDate, SellingPersonID);C. CREATE NONCLUSTERED INDEX idx2ON dbo.Selling (SellingPersonID)INCLUDE (CommentDate, CustomerID);D.

Now you areemployed in a company which is named Loxgo. The company uses SQL Server 2008 and all the company datais stored in the SQL Server 2008 database which is named DB1. There is a table named Bill in DB1. BillID is the primarykey of the Bill table. By using the identity property, it is populated. The Bill table and the BillLineItem are relatedto each other. In order to increase load speed, all constraints are removed from the Bill table during a data load. But arow with BillId = 10 was removed from the database when you removed the constraints. Therefore you have tore-insert the row into the Bill table with the same BillId value. Of the following options, which Transact-SQL statementshould be used?A. INSERT INTO Bill(BillID, ...VALUES (10, ...B. SET IDENTITY_INSERT BillON;INSERT INTO Bill(BillID, ...VALUES (10, ...SET IDENTITY_INSERT BillOFF;C.

Now you areemployed in a company which is named Loxgo. The company uses SQL Server 2008 and all the company datais stored in the SQL server 2008 database. According to the business needs, an XML schema must be used to validateXML data in your database. So of the following code segments, which one would be used to store this XML schema?A. CREATE XML SCHEMA COLLECTION ClientSchema would be used to store this XML schemaB. CREATE DEFAULT XML INDEX ClientSchema would be used to store this XML schemaC. CREATE SCHEMA ClientSchema would be used to store this XML schemaD. CREATE DEFAULT ClientSchema AS XML would be used to store this XML schemaE. CREATE PRIMARY XML INDEX ClientSchema would be used to store this XML schema.Answer: AQUESTION 64 You are a database developer and you have many years experience in database development. Now you areemployed in a company which is named Loxgo. The company uses SQL Server 2008 and all the company datais stored in the SQL server 2008 database. A table named Client has an XML column named Places, which has an XMLfragment with details of one or more places stored. You can see it from the following examples: <Place City="Tokyo" Address="..." PhoneNumber="..." /> <Place City="Ohio" Address="..." PhoneNumber="..." /> <Place City="Paris" Address="..." PhoneNumber="..." /> Now you are assigned a task to write a query that returns a row for each of the clients places to meet thefollowing needs: Each resulting row includes an XML fragment that contains the place details. Each resulting row includes the city. Each resulting row includes the client name. So which query would be used to accomplish this task?
  29. 29. A. You should use the query that SELECT ClientName Places.query(data(/Place/@City)), Places.query(/Place) FROM ClientB. You should use the query that SELECT ClientName, Places.query(for $i in /Place return data($i/ @City)), Places.query(for $i in /Place return $i) FROM Client.C. You should use the query that SELECT ClientName, Loc.value(@City,varchar(100)), Loc.query(.) FROM Client CROSS APPLY Client.Places.nodes (/Place) Locs(Loc)D. You should use the query that SELECT ClientName, Places.query(for $i in /Place return element Place {$i/@City, $i}) FROM ClientAnswer: CQUESTION 65 You are a database developer and you have many years experience in database development. Now you areemployed in a company which is named Loxgo. The company uses SQL Server 2008 and all the company datais stored in the SQL server 2008 database. You have two tables named Clients and Bills. Bills table is related to theClients table on the ClientID by a foreign key constraint. Now according to the requirement of your manager, the XML structure that contains all clients and theirrelated bills should be generated as the following: <Root> <Client> <ClientName>Client1</ClientName> <Bills> < Bill ><BillDate>1/1/2008</BillDate><BillValue>422</BillValue></Bill> <Bill><BillDate>4/8/2008</BillDate><BillValue>300</BillValue></Bill> ... </Bills> ... </Client> <Root> So of the following queries, which one should you choose to meet your manager??s requirement?A. SELECT ClientName, (SELECT BillDate, BillValue FROM Bills FOR XML PATH (Bill)) FROM Clients FOR XML PATH(Client), ROOT(Root), TYPEB. SELECT ClientName, (SELECT BillDate, BillValue FROM Bills WHERE Bills.ClientId = Clients.ClientId FOR XML PATH(Bill), TYPE) Bills FROM Clients FOR XML PATH(Client), ROOT (Root)C. SELECT ClientName, BillDate, BillValue FROM Clients c JOIN Bills o ON o.ClientID = c. ClientID FOR XML AUTO, TYPED. SELECT * FROM (SELECT ClientName, NULL AS BillDate, NULL AS BillValue FROM Clients UNION ALL SELECT NULL, BillDate, BillValue FROM Bills) ClientBills FOR XML AUTO, ROOT(Root)Answer: B
