Colin's reply will help you understand the folly of your question as written. A single erb file won't connect to a MySQL database on its own, within the context of a Rails application, ever. The View is responsible for showing the data, not fetching it or responding to user input.

If you have a full Rails application there, and not just a single erb file, you may have a different question. But until you come to grips with the basics of how Rails works, I doubt you're going to get much of an answer here that makes sense to you until you can formulate your question in another manner.
