Seriously, if you think MySQL is anywhere near as scalable as MS SQL, you are delusional. I've used all of the database softwares out there and only MS SQL is standard, scalable and fast, Oracle is scalable and fast but not standard by a long shot, killing productivity. MySQL is neither fast, scalable nor standard. I really don't understand what anyone sees in that piece of shit when at the very least they can have PostgreSQL which excels on all accounts and is open sourced. I blame popularity contests.
