Need stored procedure that shows one value for null and another for not null

I have a stored sprocedure with two parameters that currently searches a table for a matching record see SQL below:

**************************************************************

@.WorkOrderNum numeric(18,0)

,@.StackNum numeric(18,0)

AS

--This procedure is used in iFIX. It looks for matching

--Work Order Number / Stack Number combination.

SELECT

work_order_no

,stack_no

FROM

dbo.prod_data

WHERE

(dbo.prod_data.work_order_no = @.WorkOrderNum)

AND (dbo.prod_data.stack_no = @.StackNum)

******************************************************************************

What I need is a stored procedure that will look for a matching criteria and if it finds some it will return a value of "2", if it does not find any criteria it needs to return a value of "1". This value does not need to be stored, for display only.

Any help would be greatly appreciated

You could do below:

Code Snippet

select case when exists(

SELECT *

FROM

dbo.prod_data as p

WHERE

p.work_order_no = @.WorkOrderNum

AND p.stack_no = @.StackNum
) then 2 else 1 end as matched
