    i get an error at from with the update statment.

    can't we do this with a single query? stored procedure?

    You can do this with a single query only if you're on SQL 2008. Then you can use the MERGE statement.

    Until then, you need to do the UPDATE, followed by the INSERT, to do this. Lutz gave a great example; use it.
