Latest news about using Bind variables with oracle.

Whats the latest news with the use of real bind variables with Oracle?

A couple of years ago it was mentioned that it was a planned feature for rails. I haven't heard anything since about it.

The advantages of them in my organization would be massive. I have just optimized a large query in Java by making it use bind variables. This reduced the time of execution from 0.8 seconds to 0.002 seconds. This query is called often and the optimization has noticeably sped up the system.

It is a shame that its currently impossible to use bind variables. It would make my organization take rails more seriously if it would.

Thanks Chris
