I'm trying to insert the word "Null" (literally) in to a parameter for a stored procedure. For some reason SqlServer seems to think I mean NULL and not "Null". If I do a check for

IF @LastName IS NULL // Test: Do stuff

Then it bypasses that because the parameter isn't null.

But when I do:

INSERT INTO Person (<params>) VALUES (<stuff here>, @LastName, <more stuff here>); // LastName is 'Null'

It bombs out saying that LastName doesn't accept nulls. I would seriously hate to have this last name, but someone does... and it's bombing the application. We're using SubSonic 2.0 (yeah, it's fairly old but upgrading is painful) as our DAL and stepping through it, I see it does create the parameters properly (for what I can tell).

I've tried creating a temp table to see if I could replicate it manually but it seems to work just fine. Here is the example I create:

DECLARE @myval VARCHAR(50)
SET @myval = 'Null'
CREATE TABLE #mytable( name VARCHAR(50))
INSERT INTO #mytable VALUES (@myval)
SELECT * FROM #mytable
DROP table #mytable

Any thoughts on how I can fix this?
