I\'ve been reading about SQL injection attacks and how to avoid them, although I can never seem to make the \"awful\" examples given work, e.g. see this post
There are a lot of different ways to perform a SQL Injection and quite a lot of ways to bypass basic safety precautions.
Those attacks have been within the top 10 web application vulnerabilities (rank #2) according to OWASP.
For more information, please refer to Top 10 2007-Injection Flaws.
