dynamic sql pivot in sql server

Question

Running this query in sql server 2008 now, but soon plan to move it in creating a report in sql reporting services:

SELECT * from ( SELECT Amount, Year, col         


        

Answer 1

You are close, but for this to work you have to construct your PIVOT using dynamic SQL and then execute it. So, after you populate your variable @Year, you need to do something like this:

DECLARE @Query VARCHAR(MAX)

SET @Query = '
SELECT * from ( SELECT Amount, FYYear, column1, column2,column3 from BUYSCTE ) BUY 
PIVOT( SUM(Amount) FOR FYYear in ('+ @Year + ') ) pvt'

EXEC(@Query)

Though before doing this, you should take a look at this link.
