Hi,

It's quite simple. You can do this with UNPIVOT.

Query:

SQL

SELECT [Month],
       Result
FROM
(select 
 sum (case when [Month] = 1 then forecastdemand else 0.0  end ) January,
 sum(case when [Month] = 2 then forecastdemand  else 0.0 end) February,
  sum(case when [Month] = 3 then forecastdemand  else 0.0 end) March ,
 sum(case when [Month] = 4 then forecastdemand  else 0.0 end) April ,
 sum(case when [Month] = 5 then forecastdemand  else 0.0 end) May ,
 sum(case when [Month] = 6 then forecastdemand  else 0.0 end) June ,
  sum(case when [Month] = 7 then forecastdemand  else 0.0 end) July ,
 sum(case when [Month] = 8 then forecastdemand  else 0.0 end) August ,
  sum(case when [Month] = 9 then forecastdemand  else 0.0 end) September ,
 sum(case when [Month] = 10 then forecastdemand  else 0.0 end) October ,
 sum(case when [Month] = 11 then forecastdemand  else 0.0 end) November ,
 sum(case when [Month] = 12 then forecastdemand  else 0.0 end) December 
from forecastreorder as result
where Productid = 2) AS SourceTable
       UNPIVOT (Result
               FOR [Month] IN ([January],
                               [February],
                               [March],
                               [April],
                               [May],
                               [June],
                               [July],
                               [August],
                               [September],
                               [October],
                               [November],
                               [December])) AS UnpivotTable;

Result:

XML

Month		Result
January		500.0
February	200.0
March		300.0
April		400.0
May		0.0
June		0.0
July		0.0
August		0.0
September	0.0
October		0.0
November	0.0
December	0.0

You can eliminate rows with [Result] = 0 by adding WHERE Result > 0.
