Hello I have a system where users are able to buy tickets to shows etc.
Right now I use the MyISAM as tabletype but I would like to try InnoDB to make safe transactions. For the moment I use a TABLE LOCK to make sure that the same ticket isn't sold twise. One of the table consists on these 3 fields: (order_id, show_id, seat_id) So a normal script does this: Lock tables select to see if the tickets is already sold insert new sold ticket if no one is already there unlock Obviously I don't want another user to insert a new ticket just after if checked but right before current user inserts. Now - how would I do this with InnoDB to make it safe?
