Troy Hunt

Let me demonstrate precisely the problem: have a look at this code from a blog post about how to build a password reset feature (incidentally, read the comment from me and you'll understand why I'm happy sharing this here): There are two SQL statements here: the first one is resilient to SQL injection.
