This is the story of one such time that I stumbled upon something interesting, and all because I made a mistake. I was doing testing for the previous post (mentioned above) and somehow entered an extra character, or forgot the closing quote on a string literal, or something. Either way, I submitted some T-SQL in the sqlcmd utility that should have produced a parsing error. But instead, it cancelled the entire query batch, and without returning any errors.
Read on to learn more and maybe have a little fun with co-workers.
