I have a standalone batch program that is going to move data between two

I am taking advantage of the AR connection semantics in database.yml to
get connections to these two DBs.  But I want to do all of my DB access
at the DBI/DBD level for performance reasons.

I am having trouble getting access to the underlying DBI handle so that
I can prepare SQL statements, execute them etc.

From a connection retrieve via AR::Base.retrieve_connection, how can I
get at the DBI handle?

Is it possible that I've misunderstood that AR DB access is built on top
of DBI?

Upon further inspection, I see that AR doesn't depend on DBI.  I wonder
why not...

As it turns out, I'm in a JRuby environment, so I can just do prepared
statements via that method.
