A query in multiple tables

[eluser]earlyriser[/eluser]
ray73864: I used your approach and I got:
Error Number: 1109
Unknown table 'c' in field list
SELECT w.name, c.rating FROM (`wines` w) JOIN `wine_comments` wc ON w.id = wc.wine_id WHERE `user_id` = '2'

I wonder what w, c and wc does mean.

Thanks
