FROM (SELECT CurDate, YEAR(CurDate) AS orderyear, Warranty_Info
FROM eod_main where year(CurDate)>=2009 and year(CurDate)<=2011) AS D

3 0 224 33 77 31
some kind of problem is there in my query and that is why it is returning multiple data for same month like
please help me to have the right query. thanks

Answer 1

Instead of using CurDate as the full date with year, month and day, I would suggest using the Month() function to return the numeric value of each month. This will allow you to group by month instead of the full date:
SELECT dateMonth, [2009],[2010],[2011]
FROM
(
SELECT month(CurDate) dateMonth,
YEAR(CurDate) AS orderyear, Warranty_Info
FROM eod_main
where year(CurDate)>=2009
and year(CurDate)<=2011
) AS D
PIVOT
(
SUM(Warranty_Info)
FOR orderyear IN([2009],[2010],[2011])
) AS P;
