My coworker found this interesting little SQL Server behavior today that was quite startling at first glance. It's like punching 2 + 2 into your calculator and having the result come back as 5. After pin-pointing the cause for the behavior, it ALMOST makes sense... except for the fact that it doesn't make sense at all. It involves a randomized sub-select and table variables.
