Back to work! A long time ago, in a galaxy not far away, one of my peers dropped a couple of the most important production tables in the most important application of our most important customer. I thought it would be a tough act to follow... till today, even if I was only working on small and relatively unimportant tables. So, when you are testing a system, ALWAYS double check which one you are working on.
Luckily, we believe in the three divinities of software: backup, backup and backup, so everything went back to normal unnoticed.
