T-SQL and Fun Puzzles

Rob Farley puzzles it out:

Back in my uni days I remember a Prolog assignment to solve “each letter represents a number” puzzles, and my solution being slow. Years later I tried it again and it worked out just fine, but by then the due date was in the past and they weren’t prepared to change my grade.

While these kinds of things can be fun (more so when there aren’t uni grades dependent on the solution), there are also times that it can be fun to rewrite some code in a way that is more intuitive, or that feels clever in a profoundly simple way.

Rob shares links to a few examples along those lines.
