I do not use join’s much, but, here are two nice tutorials on how they work.
This one is simple and down-to-earth. Press next-chapter link to continue to more and more…
http://www.w3schools.com/sql/sql_join.asp
This one has tutorials on many many different types of joins. Press on a link to a type of join and it will take you to a lot of info on it with examples. I suggest walking thru the plain “join” link first…
