optional parameters in SQL Server stored proc?

Question

I\'m writing some stored procs in SQL Server 2008, and wondered if the concept of optional input parameters is possible here?

I suppose I could always pass in NULL

Answer 1

2014 and above at least you can set a default and it will take that and NOT error when you do not pass that parameter. Partial Example: the 3rd parameter is added as optional. exec of the actual procedure with only the first two parameters worked fine

exec getlist 47,1,0

create procedure getlist
   @convId int,
   @SortOrder int,
   @contestantsOnly bit = 0
as
