@Andy That’s cool. This stupid post written 8 months ago is STILL my top trafficked post. It was written on a while driven by a rant :-)

JJ…

You should feel quite privileged to have Rudy comment on your blog. He’s a SQL master, and a prolific poster over at the Sitepoint forums. He’s also a Canuck, and a great frisbee golf player.

He’s helped me increase my skills in SQL over the last 7 or 8 years.

wow …
great topic
since i’m not a good trained programmer
just a learning by doing programming
so all i do just write a run programming

and rarely think about performance,
notably with a deadline

thanks

I’ve seen worse coding before…

In my first ever job, I saw an end of day process that took 30-60 minutes, I was asked to try and shave a few minutes off of this..

I managed to reduce it to 30 seconds…

All this was in a language called Uniface, something I hope to avoid ever using again…

No I don’t have a “formal” education. I started working early and have gotten a degree in real-life experience.

Hmmm … this environment sounds eerily familiar! You must not have a formal education with 10 years experience and being 28? Just an observation about your experience claim.

I agree with Sana … outer joins are not that inefficient with relevant indexes. It goes without saying that proper database design can save a few headaches.
