SQL Server Question of the Day

One of the tenants I live by is continuous learning. With my technical expertise based in SQL Server, I read the Question of the Day on SQL Server Central to test my knowledge and hopefully learn a new nugget that I can apply to my daily job. I have decided to post a few questions myself in order to share some of my experiences with the larger SQL Server crowd. Look for my next question that will be posted on Monday, October 12th, 2009. Hopefully you will participate and get the correct answer. Good luck and keep learning!
