This is the actual table.
Month RCount Cond_Id Cond_desc
Jan-13 52 -1 N/A
Jan-13 194 0 NORMAL
Jan-13 86 2 ABNORMAL
Feb-13 54 -1 N/A
Feb-13 158 0 NORMAL
Feb-13 110 2 ABNORMAL
Mar-13 14 -1 N/A

Mar-13 90 2 ABNORMAL
Apr-13 3 -1 N/A

May-13 305 2 ABNORMAL
May-13 1 4 CRITICAL
Jun-13 169 0 NORMAL
Jun-13 36 2 ABNORMAL
Jun-13 1 4 CRITICAL
I need the following results.
R_id Cond_Id Cond_desc Jan-13 Feb-13 Mar-13 Apr-13 May-13 Jun-13
1 -1 N/A 51 54 14 3 10 169

3 2 ABNORMAL 86 110 90 144 305 1
4 0 CRITICAL 0 0 0 0 1 0

Answer 1

Assuming that you wont this:
Sum the values of rcount grouped by month.
The value of COND_ID in your example is wrong, for example for the case CRITICAL the value should be 4.
The field R_ID (rownumber) is only a count of the query.
The following query maybe will be useful:
DECLARE #cols AS NVARCHAR(MAX),
#query AS NVARCHAR(MAX)
select #cols = STUFF((SELECT ',' + QUOTENAME([MONTH])
from MYTABLE
group by [MONTH]
order by [MONTH]
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set #query = 'SELECT ROW_NUMBER() over (order by COND_ID) AS R_ID,COND_ID,COND_DESC,' + #cols + '
from
(
SELECT
COND_ID,
COND_DESC,
rcount,
MONTH
FROM MYTABLE
) x
pivot
(
sum(rcount)
for [MONTH] in (' + #cols + ')
) p '
execute sp_executesql #query;
Here you try this sql fiddle.
This query I've created from the bluefeet's link.
