Using ruby on rails with Oracle Legacy.

Great slide on SlideShare.
introduces the ruby-plsql gem, which makes it easier to preform database functions and stored procedures from ruby/rails applications (and supports bind variables).
i personally wrote a module of my own to handle this need (which supports bind variables as well).
Check out the slide and pay attention to the oracle_enhanced_adapter now available.
The slide is over here at SlideShare.
