    2005+ (as it uses PIVOT).

    It only took 11 seconds to run on my local VM, so I think you'll be alright ;)

    It was fun running it on the live production server, 12 seconds :[D

    This reminds me of when (many years ago now) we sent a postscript file to our brand-new 300dpi printer which computed and displayed the Mandelbrot set at maximum resolution, with all computations performed in the PS interpreter. I don't remember if it was an overnight job or an "over a long weekend" job, but it was definitely awesome...

    No, I don't have the code.

    A friend of mine once coded the solution to the Towes of Hanoi. In Postscript. Fully animated. Too bad he left out all the showpage commands :-) But it looked pretty in Ghostscript.

    Incidentally, here's the same query for Postgres:

    Great. Another loser heard from who has to get his kicks from criticizing typos. Yay.

    We adults with basic reading skills knew what he meant. Perhaps you should take a class.

    Well, not quite kicks, exactly. It's just that those of us with better than basic writing skills like to point and laugh. You know, peer pressure and all that.

    That's a bit harsh. Vista has proven to be a terrific platform for running many critical applications, such as Norton Antivirus, Spybot Search & Destroy, O&O Defrag, Ad-Aware, RegOptimizer, and it even comes with Windows Update and System Restore!! That's a hell of a lineup!

  • Paul Nicholls (unregistered)

    Ok, so maybe I went a little mad. I used this T-SQL as a base to construct a JS (and thus entirely client-side) ASCII-Art Mandelbrot explorer - allowing you to zoom in and out and move around the "image" at will. It's considerably quicker than the T-SQL version, though it's not instant (and speed will of course depend on your hardware). Enjoy!

    Jaw droppingly cool...

    But how do you get it to "zoom in" to one of the curls?

    Modify the values in the Cast() statements. The first value is the starting point and the second value is the step size for each of IX and IY.

  • (cs)

    It actually is pretty cool code. I'd give bonus point for the use of a CTE and PIVOT.
