Dynamic PIVOT in SQL Server 2005 - sql-server-2005

Question

i rare use PIVOT in sql server but now requirement is something that i have to use PIVOT.
my table structure is something like
CurDate Warranty_Info
------- -------------
01/01/2009 50
01/05/2009 30
01/03/2009 220
01/01/2010 40
01/06/2010 10
01/02/2010 0
01/01/2011 10
01/05/2012 420
01/05/2013 130
now i have to show the data in this way
Month 2009 2010 2011 2012 2013
----- ---- ---- ---- ---- -----
JAN 10 0 11 32 98
FEB 20 10 21 11 44
MAR 0 224 33 77 31
UPTO
DEC
1) data should display month wise order....so jan first
2) if no data exist in any month then month name will come with 0 as value for that month.
i tried but fail. here is my sql by which i tried.
SELECT *
FROM (SELECT DateName(month,DateAdd(month,Month(CurDate),-1)) as [Month],
YEAR(CurDate) AS WarrantyYear,
Warranty_Info
FROM eod_main) AS D
PIVOT (
SUM(Warranty_Info)
FOR WarrantyYear IN (
[2009],[2010],[2011],[2012],[2013]
)
) AS P
ORDER BY DATENAME(MONTH,DATEADD(MONTH, [Month] - 1, 0))
and i tried to generate sql dynamically this way.
DECLARE #cols AS NVARCHAR(MAX)
DECLARE #PivotTableSQL NVARCHAR(MAX)
DECLARE #StartYear AS INT,
#EndYear AS INT
SET #StartYear=2009
SET #EndYear=2013
select #cols = STUFF((SELECT ',' + QUOTENAME(Year(CurDate))
from eod_main
WHERE Year(CurDate)>=#StartYear AND Year(CurDate) <=#EndYear
group by Year(CurDate)
order by Year(CurDate)
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
SET #PivotTableSQL = N'
SELECT * FROM (
SELECT Month(CurDate), YEAR(CurDate) AS WarrantyYear,Warranty_Info FROM eod_main) AS D
PIVOT (
SUM(Warranty_Info)
FOR WarrantyYear IN (
' + #cols + '
)
) AS PivotTable
'
print #PivotTableSQL
but some where i am facing problem like
1) display month name
2) order by month no
3) null value show show 0 instead of NULL
4) if no data exist for any month then month name should display with 0 value.
please guide me how to achieve it. thanks

Hi Find the Below Solution, i hope that it is help full to you
SELECT CAST('01/01/2009' AS date) CurDate , 50 Warranty_Info INto #temp UNION all SELECT
CAST('05/01/2009' AS date) , 30 UNION all SELECT
CAST('03/01/2009' AS date) , 220 UNION all SELECT
CAST('01/01/2010' AS date) , 40 UNION all SELECT
CAST('06/01/2010' AS date) , 10 UNION all SELECT
CAST('02/01/2010' AS date) , 0 UNION all SELECT
CAST('01/01/2011' AS date) , 10 UNION all SELECT
CAST('05/01/2012' AS date) , 420 UNION all SELECT

declare #years varchar(max), #yearsColumns varchar(max)
SELECT #years=COALESCE(#years+',','') +'['+ cast(years as varchar(4))+']',
#yearsColumns=COALESCE(#yearsColumns+',','') +'isnull(['+ cast(years as varchar(4))+'],0) as ['+cast(years as varchar(4))+']'
from (select distinct YEAR(CurDate) years from #temp) as x
print #years
DECLARE #query varchar(max)= '
select months,'+#yearsColumns+' from (
select distinct mID, YEAR(CurDate) years,[MONTH] months, isnull(Warranty_Info,0) as Warranty_Info from #temp
right join #tempMonths on datename(month,CurDate ) =[month]
) as xx
PIVOT
(
SUM(xx.Warranty_Info) FOR years IN ('+#years+')
)
as pvt ORDER BY mID'
PRINT #query
EXEC(#query)
output islike below
months 2009 2010 2011 2012 2013
