Getting Null data while using PIVOT in sql server 2008 R2 - sql

Question

I am using the following query with PIVOT:
SELECT *
FROM (
SELECT
MEMBER_PROPERTY as [MEMBER_PROPERTY],MEMBER_VALUE as MEMBER_VALUE,
MEMBER_ID as MEMBER_ID
FROM MEMBER_ATTRIBUTES) as s
PIVOT
(
max(MEMBER_PROPERTY)
FOR [MEMBER_VALUE] IN (['My main interests'], traveling,accommodation, prizedraw)
)AS test
This query returns Null for "['My main interests'], traveling,accommodation, prizedraw" columns, i am not getting why, as the table has data for these columns for each record..
Please help me how can I get data.

I think this will help you.we should use QuoteName function for space column.
CREATE Table #MEMBER_ATTRIBUTES (
MA_ID int,
MEMBER_ID int,
MEMBER_PROPERTY varchar(100),
MEMBER_VALUE varchar(100)
)
insert INTO #MEMBER_ATTRIBUTES values(1,1,'My Main Interests','traveling')
insert INTO #MEMBER_ATTRIBUTES values(2,1,'I m Most Likly to be travelling','With a parents')
insert INTO #MEMBER_ATTRIBUTES values(3,2,'My Main Interests','prizedraw')
insert INTO #MEMBER_ATTRIBUTES values(4,2,'I m Most Likly to be travelling','With my wife')
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
SELECT #cols= stuff((
SELECT ', ' +QUOTENAME(MAX(MEMBER_PROPERTY))
FROM #MEMBER_ATTRIBUTES
group by MEMBER_PROPERTY
order by MEMBER_PROPERTY
FOR XML PATH('')), 1, 2, '');
SET #query = 'SELECT MA_ID,MEMBER_ID, ' + #cols + '
from
(
SELECT MA_ID,MEMBER_PROPERTY as [MEMBER_PROPERTY],MEMBER_VALUE as MEMBER_VALUE,
MEMBER_ID as MEMBER_ID FROM #MEMBER_ATTRIBUTES
) x
pivot
(
MAX(MEMBER_VALUE)
for x.MEMBER_PROPERTY in (' + #cols + ')
) p'
execute sp_executesql #query;
