Does anyone have an example of how this feature works? I'm
still reasonably new to JDBC and I want to get this working
properly. I'm at a loss of how to implement the driver
differently than I already have. Any and all help is
appreciated.
Basically I am trying to get the ResultSetMetaData to work.
(See the code snippet below)

I'll check the current source to make sure nothing is broken, but this
is supported (and has been for quite some time)
If you have some sample code to test this please let me know, If there
is code in the release that I am too blind to see then let me know too
