Question

Is it possible to create a stored procedure as

CREATE PROCEDURE Dummy 
    @ID INT NOT NULL
AS
BEGIN
END

Why is it not possible to do somet

Answer 1

You could check for its NULL-ness in the sproc and RAISERROR to report the state back to the calling location.

CREATE   proc dbo.CheckForNull @i int 
as
begin
  if @i is null 
    raiserror('The value for @i should not be null', 15, 1) -- with log 

end
GO

Then call:

exec dbo.CheckForNull @i = 1 

or

exec dbo.CheckForNull @i = null
