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

Yes, it is. Declare parameter as so:

@Sort varchar(50) = NULL

Now you don't even have to pass the parameter in. It will default to NULL (or whatever you choose to default to).
