I liked it, thank you.
Neatly set out, easy to follow and it does exactly what it says on the title.

I followed the link at the bottom of the page to the other highlighted SQL tut, and it too is a good solid tut, but this one is just easier on the eye .............. [personal preference]

I've been playing with SQL for a while, and I just needed a tut like this, concise and to the point.
The books I've been reading, have had to cover all the bases, and it made it quite a struggle to get through.
