Unfortunately I can’t update the image as it’s outside my control.

just one cosmetic thing, on slide 48 there is a minor type while giving the hint “materialize”

When you get the pop-up window that is supposed to show the demo, but fails to find it, the URL needs to be changed so that “Demo.html” becomes “demo.html”.

Corrected URL for demo

I’ve sent an email to the person at Oracle who set up the Webcast, so this may change at some future point.

As far as NULLs go, I don’t think I could do anything better than this note,written a couple of years ago by Lex de Haan and Jonathan Gennick.

I understand how they work but I’ve seen enough people get tripped up by them…

excellent presentation. Thank you for sharing this. It’s amazing what there is to learn about a ‘simple’ join.

I made only a personal copy following more or less what Gary suggested.

For mirror I meant a download for personal use not for publication.

If someone are interested I must say that what Gary said is correct but not complete.

That’s all.

P.S.
Jonathan if you think that it’s better to edit or delete this comment…well you’re welcome! :)
