    - by Andrey
    I have written an O/R database wrapper that generates some wrapper methods for stored procs it reads from the database. Now I need to produce some custom wrapper code if an input parameter of a stored proc is defaulted to NULL.

Are they stored anywhere in the database? BTW, I'm using SQL Server 2008
