title: Empty my Sqlite3 database in RoR
body: <p>I am working on a Ruby on Rails 3 web application using sqlite3. I have been testing my application on-the-fly creating and destroying things in the Database, sometimes through the <code>new</code> and <code>edit</code> actions and sometimes through the Rails console.  </p>
  
  <p>I am interested in emptying my Database totally and having only the empty tables left. How can I achieve this?  I am working with a team so I am interested in two answers:
  1) How do I empty the Database only by me?
  2) How can I (if possible empty) it by the others (some of which are not using sqlite3 but MySql)? (we are all working on an the same project through a SVN repository)</p>
