Subject: [dba-SQLServer]Help with stored procedure


In a stored procedure report, how do I allow an optional filter for a
select 
statement/

For example:

use pubs
go
CREATE PROCEDURE au_info @lastname varchar(40), @firstname varchar(20)
AS SELECT au_lname, au_fname FROM authors WHERE au_lname = @lastname and
au_fname = @firstname go EXECUTE au_info @firstname = null, @lastname =
'Ringer' GO DROP PROCEDURE au_info

I want the stored procedure to return all records where last name is 
"ringer" (there should be two of them) but right now it returns nothing.

Thanks in advance,
Billy
