Stupid Coding Tricks: The T-SQL Mandelbrot
The bar for entry into CodeSOD is pretty straight forward: professionally-developed code that elicits that certain What The— reaction. Though there have been a few exceptions over the years, generally speaking, student code, hobbyist code, and amateur code need not apply. That said, I'd like to try something a little different today. Today's example is not technically professionally-developed, it's a Stupid Coding Trick.
"So I was bored at work one day," Graeme Job explains, "and wondered, what's the most useless thing I could do with my time without actually doing anything. Then it hit me. I could use T-SQL to generate... Mandelbrot."
Graeme continued, "Following is a single T-SQL SELECT statement that generates a text-representation of a Mandelbrot Set. The results are best viewed in text-mode."
