Subject: [PATCH 2/3] SQL requests updated to support MySQL

This is a (working) temporary solution based on SQL requests provided here: https://github.com/copycopter/copycopter-server/issues/64#issuecomment-5836709. Works for MySLQ and Postres; should be updated with ActiveRecord methods calls to be database agnostic.
