Can you offer best practices to avoid SQL (Server) injection?

. The Web site is run by Chip Andrews, the fellow who coined the phrase "SQL injection." Most of the advice follows a repeating battle cry: Sanitize all data coming in to your application (whether from human input, browser user-agent strings or cookies). Validate that when you're expecting a numeric, you receive a numeric. Most of it is simple once you get the hang of it, but it's a pain when you're trying to whip out a quick Web application. The trouble is quick Web apps tend to grow into enterprise mission-critical systems. Things that didn't seem important when you were making a quick little program to track jelly beans (such as data input validation) become monstrous issues when your application controls the worldwide inventory of a Jelly Bean factory.
