Cross Tab in sql 2008

I am new to SQL SERVER 2008. I have a table tblUserInterest (id, User_Id, Interest_word, Weight) And other table as tblUser (id, UserName, Password, UserType)

I have data in tblUserInterest as,
id  User_Id   Interest_word                     Weight
--------------------------------------------------------------------------------
1        3         www.cooltoad.com                   6
2        3         www.google.co.in                     3
3        2         www.cooltoad.com                   1
4        2         www.google.co.in                     18

User 2 : Swati
User 3 : Sonali
I want to attach a result to grid which should be in format


UserName       www.cooltoad.com        www.google.co.in                               
---------------------------------------------------------------------------------------------
Swati                          1                                  18
Sonali                         6                                    3

use Pivot operator   (more Using PIVOT  http://msdn.microsoft.com/en-us/library/ms177410.aspx)

try this below basic  code  (if you need more - use dynamic code)



   SELECT *
   FROM (
   select case when USER_ID=2 then 'Swati'
              when USER_ID=3 then 'Sonali ' end UserName , Interest_word ,  Weight from tblUserInterest
   ) AS PivotData
   PIVOT (
     max(Weight)
     FOR Interest_word  IN (
       [www.cooltoad.com],[www.google.co.in]
     )
   ) AS PivotTable

The only way I know without having to "hardcode" the Interest_word it's whit a loop and temp table.

I will be happy to see someone do it without a loop!!

CREATE TABLE tblUser 
(
	id int
	, username varchar(150)
)
CREATE TABLE tblUserInterest
(
	iUser_id int
	, Interest_word varchar(150)
	, Weight int
)

INSERT INTO tblUser
SELECT 1, 'TEST1' UNION ALL 
SELECT 2, 'TEST2' UNION ALL 
SELECT 3, 'TEST3' 

INSERT INTO tblUserInterest
SELECT 1, 'INTEREST1', 100 UNION ALL 
SELECT 1, 'INTEREST2', 150 UNION ALL 
SELECT 1, 'INTEREST3', 110 UNION ALL 
SELECT 2, 'INTEREST1', 110 UNION ALL 
SELECT 2, 'INTEREST3', 100 


DROP TABLE #final_Results
CREATE TABLE #final_Results
(
	iUser_id int
	, UserName varchar(150)
)

INSERT INTO #final_results
(
	iUser_id
	, UserName
)
SELECT DISTINCT
	id
	, UserName
FROM 
	tblUser 



DECLARE @Interest_word	VARCHAR(255)
DECLARE @TSQL			VARCHAR(MAX)

DECLARE cur_Interest	CURSOR
FOR 
	SELECT DISTINCT
		Interest_word
	FROM 
		tblUserInterest 

OPEN cur_Interest


FETCH NEXT FROM cur_Interest INTO @Interest_word
	


WHILE @@FETCH_STATUS = 0 
BEGIN 

	-- ADD Interest_word as column
	SET @TSQL = 'ALTER TABLE #final_Results ADD '+@Interest_word+' INT NULL'
	EXECUTE (@TSQL)
	
	-- UPDATE Weight
	SET @TSQL = 
	'
		UPDATE T
			SET '+@Interest_word+' = ISNULL(Weight,0)
		FROM 
			#final_results T
			LEFT JOIN tblUserInterest I
				ON I.iUser_Id = T.iUser_Id
				AND I.Interest_word = ''' + @Interest_word + ''' 
			
	'
	EXECUTE (@TSQL)
	

	FETCH NEXT FROM cur_Interest INTO @Interest_word
END

CLOSE cur_Interest
DEALLOCATE cur_Interest


SELECT 
	*
FROM 
	#final_results
