My site is database driven, which means that every post is held in tables in an SQL database. Otherwise, I'd have to have a separate web document for every post, which is upwards of about 900 or so. Nobody does that. If you write on a blog, it's very likely that you're using a database driven site as well.

In the world of database and web programming, you have to put in some security measures to prevent exploitation by way of an "SQL injection" attack.

I just spent the last 20 minutes doing just that. This is nerd-core mumbo jumbo for most of you, but for you web geeks, you know what I'm talking about.

Update: Today's xkdc is actually about SQL injection attacks. Fantastic.
