Hey Joe, don't you feel like you are talking for nothing sometimes???

Guys, Joe literally wrote the book on SQL, he wrote the ISO standards for SQL.  I would strongly suggest you listen to him on this one... and basically any other post he makes .

Even if it seems like overkill this time, and the next time and the time after that.  Won't you wish you had taken the time to write one when you decid to implement it the nth time... and then decid to make that the business rule to implement overall once you see the benefits??
