Quick comment, most database tools these days have a
graphic query builder. I have them for mySQL. It has
helped me, because even in the graphic builders you
still need to know whether it's a left right , outter
inner, full join. So, the builder gets all the other
stuff out of the way, all the code, and would let you
focus on the join type. A click of the mouse and you
can switch the join type, run the query and see the
difference in results. Kind of neat.
