Doing this in SQL 2008.

Is it possible to use the results of one column to calculate another column? Example:

Select .. VERY LONG FORMULA as Results1

I need another column with a CASE so..

CASE Result1 < 100 Then something as Results2

Is it possible to do something like this or do I have to do the whole long formula again like...

CASE VERY LONG FORMULA < 100 Then something as Result2

I already have Results1 and it's silly to do it again just to calculate Results2.

God I hope this isn't too confusing.

Thanks in advance.
Phil

you can do in both ways

either

CASE VERY LONG FORMULA < 100 Then something as Result2


or make first result into derved table and then use it like

SELECT ....,
CASE Result1 < 100 Then something as Results2,
..
FROM
(
SELECT ...,
VERY LONG FORMULA as Results1
FROM
....
)t
