Q&A > database programming > How can I secure MySQL & CGI? - Answer contributed by Zombie WebGuy

Actually, you can perform transactions on mySQL using a more complicated Q-language called T-SQL. I do it at work everyday in other applications. But I would definitely use Oracle if you are storing credit card info!

Just 2 cents from WebGuy!
