Group Data For Survey

hi,

i'm having following data:


create table survey
(
clientID int not null,
questionID int not null,
Answer int not null
)

insert into survey (clientID, questionID, Answer) values (1, 1, 1)
insert into survey (clientID, questionID, Answer) values (1, 1, 2)
insert into survey (clientID, questionID, Answer) values (1, 1, 4)
insert into survey (clientID, questionID, Answer) values (1, 1, 5)
insert into survey (clientID, questionID, Answer) values (2, 1, 1)
insert into survey (clientID, questionID, Answer) values (2, 1, 5)
insert into survey (clientID, questionID, Answer) values (2, 1, 8)
insert into survey (clientID, questionID, Answer) values (3, 1, 2)
insert into survey (clientID, questionID, Answer) values (3, 1, 4)
insert into survey (clientID, questionID, Answer) values (3, 1, 6)
insert into survey (clientID, questionID, Answer) values (3, 1, 9)
insert into survey (clientID, questionID, Answer) values (4, 1, 8)
insert into survey (clientID, questionID, Answer) values (5, 1, 1)
insert into survey (clientID, questionID, Answer) values (5, 1, 5)
insert into survey (clientID, questionID, Answer) values (5, 1, 9)


and i want to get it out like this:

ClientIDQ1_1Q1_2Q1_3Q1_4
----------------------------------------
1|1|2|4|5|
2|1|5|8|0|
3|2|4|6|9|
4|8|0|0|0|
5|1|5|9|0|

but i get the following output:

clientID Q1_1 Q1_2 Q1_3 Q1_4
----------- ----------- ----------- ----------- -----------
1 12 12 12 12
2 14 14 14 14
3 21 21 21 21
4 8 8 8 8
5 15 15 15 15

(5 row(s) affected)

with this code:



SELECT

distinct(clientID)
,Q1_1
,Q1_2
,Q1_3
,Q1_4


from
(select
distinct(clientID)
,sum(case when QuestionID = 1 and Answer in (1,2,3,4,5,6,7,8,9,10) then Answer else 0 end) as Q1_1
,sum(case when QuestionID = 1 and Answer in (1,2,3,4,5,6,7,8,9,10) then Answer else 0 end) as Q1_2
,sum(case when QuestionID = 1 and Answer in (1,2,3,4,5,6,7,8,9,10) then Answer else 0 end) as Q1_3
,sum(case when QuestionID = 1 and Answer in (1,2,3,4,5,6,7,8,9,10) then Answer else 0 end) as Q1_4


from
dbo.survey

group by clientid) as x

group by
x.clientID
,x.Q1_1
,x.Q1_2
,x.Q1_3
,x.Q1_4


order by clientID asc
