Thankq for your response. I need Mode column values as column name.If you mean you have more than 3 modes and don't know how many you would need to convert Mark's solution to dynamic SQL that generates the dynamic column result.
My mantra: No loops! No CURSORs! No RBAR! Hoo-uh![/I]My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.Need to UNPIVOT? Why not CROSS APPLY VALUES instead?[/url]
Since random numbers are too important to be left to chance, let's generate some![/url]

another query
select name,[Phone],[Sms],[Email]from
(
select name , mode , sum(case
when name = 'AAAAA' then 1
when name = 'BBBBB' then 1
when name = 'CCCCC' then 1 else 0 end) as cnt from @t
group by mode, name
)t
pivot
( sum (cnt)
for mode in ([Email],[Phone],[Sms])
)pvt
ORDER BY Name; but i am unable to remove NULL.

If the values in the node column can be dynamic then you can do a Dynamic Cross tab as follows :
--Creating Table
Create table Ex1
(
ID Int,
Name Varchar(30),
Mode Varchar(30)
)
--Inserting Sample Data
Insert into Ex1
Select 1, 'AAAAAAA','Phone'
Union ALL
Select 2, 'AAAAAAA','Phone'
Union ALL
Select 3, 'AAAAAAA','Phone'
Union ALL
Select 4, 'BBBBB','SMS'
Union ALL
Select 5, 'BBBBB','SMS'
Union ALL
Select 6,'CCCCC','Email'
Union ALL
Select 7, 'AAAAAAA','SMS'
--Dynamic Pivot
Declare @sql Varchar(Max)
Set @sql = 'Select Name, '
Select @sql = @sql + STUFF((Select ',SUM(Case When mode = ' + CHAR(39) + Mode + CHAR(39) + ' Then 1 Else 0 End) As ' + Mode From (Select Distinct Mode From Ex1) As a FOR XML Path('')),1,1,'')
Select @sql = @sql + ' From Ex1 Group By Name'
Execute (@sql)
