Answer 1

This approach you're trying doesn't work. But if you're on SQL Server 2008, you could make use of the new features called Table Valued Parameters.

Basically, you create a user-defined table type

CREATE TYPE dbo.nIdTable AS TABLE(nID INT)

and you can then pass in multiple values in that TVP from the outside (e.g. from ADO.NET or such):

CREATE PROCEDURE abc(@idValues dbo.nIdTable READONLY)

and use that table variable inside your stored proc:

SELECT * 
FROM table 
WHERE nId NOT IN (SELECT nID FROM @idValues)
