I'm one of those people who puts as much business logic in the database. Stored procedures, views and functions are my "middle tier". That can sometimes lead to long running procedures with little feedback from the UI. I've often wished that you could return interim status information back from SQL.
Well, it turns out you can. The MSDN blog post, "Getting feedback / progress from batches and stored procedures", details how using RAISERROR.
BTW, the article also notes why there's a missing "E" in RAISERROR.
