    SELECT

    CASE WHEN 2009 = 2009 THEN 1

    DECLARE @a varchar(10) -- declaration of variable

    SET @a = DATEPART(YEAR,DATEADD(YEAR,0,'01/01/2009'))

    DECLARE @SQL NVARCHAR(200)

    SELECT @SQL = 'SELECT CASE WHEN 2009 = 2009 THEN 1

    ELSE 0

    END AS '+ QUOTENAME(@A) +''

    EXECUTE( @SQL)

    Just curious... why do you need to do this?

    RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
    First step towards the paradigm shift of writing Set Based code:
    ________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

    Change is inevitable... Change for the better is not.
