The basic difference between Id and class it that, an ID can be applied to only single type of elements no matter how many times you apply or how many ids you create but in slight edge class is same as id but can be applied to different types of elements Am I Right?

What if I want to execute "SELECT customers.Name, customers.ID, items.Name, items.Seller_id FROM customers LEFT OUTER JOIN items ON customers.ID=items.Seller_id;" Will there be two more column displayed with the customer id and seller id?

Hmm. But in the case we delete a row (toghether with the ID) there will be a gap between the sequence of the ID's. Does auto_increment fill that gap when a new user is created, or will it just add 1 to the last id in the table?
