... just realised - I left out the most important bit of the select SQL (can you tell I didn't actually try it out ;-)))
It should have read:
select a.name, b.street, b.state, b.post_code from one a, two b where a.id = 0 and a.address = b.id;
Otherwise, we're not 'joining' on the two tables.
Also, if you need more info on SQL, just use google to do a search on "SQL tutorial". Should come up with plenty of info. Once you're familiar with how everything works in principal, the MySQL online docs have a very extensive section on the exact SQL syntax used by MySQL - you'll never need any other SQL documentation than that ;-)
