Thanks for the pointer to this presentation, Oyvind. It's a pretty startling observation though I'm not sure how to use it. I'd be interested in hearing your thoughts about this some time.

Cheers,

That reminds me of a very entertaining presentation which was held at VLDB this year:

Slides: http://www.vldb2005.org/program/slides/fri/s1228-reddy.ppt
Paper: http://www.vldb2005.org/program/paper/fri/p1228-reddy.pdf

Have a look, it's worth the time.

We should definitely consider more execution plans in Derby, so that we, too, could draw such interesting pictures. ;o)
