datepart datatype

On a paramater of datepart (like the first one in DateAdd),
can I in any chance pass a parameter?
(and not use the constants week, month etc.)
SELECT DateAdd(@.my_dt , 1 , CONVERT (DATETIME, '01/01/01')) As 'Date'
I think you would need dynamic SQL, e.g.
EXEC('SELECT DateAdd(' + @.my_dt + ', 1, ...') AS [Date];

DECLARE @.d datetime
SET @.d = GETDATE()
DECLARE @.x int
SET @.x = 7
SELECT CASE @.x
WHEN 1 THEN DATEPART(year, @.d)
WHEN 2 THEN DATEPART(quarter, @.d)
WHEN 3 THEN DATEPART(month, @.d)
WHEN 4 THEN DATEPART(dayofyear, @.d)
WHEN 5 THEN DATEPART(day, @.d)
WHEN 6 THEN DATEPART(week, @.d)
WHEN 7 THEN DATEPART(weekday, @.d)
WHEN 8 THEN DATEPART(hour, @.d)
WHEN 9 THEN DATEPART(minute, @.d)
WHEN 10 THEN DATEPART(second, @.d)
WHEN 11 THEN DATEPART(millisecond, @.d)
END as SomePart
