What are the options and what each of them do? These have to do with Foreign Key Constraints. If you're using InnoDB tables, you could let MySQL automatically drop any child objects by using ON DELETE CASCADE. NO ACTION will raise an exception if there are child objects and you're trying to delete/update a parent row.
