If your UDF return an ResultSet (or constructed SimpleResultSet class), that 
can be used as a table too for anything you want.

Interesting approach, but that create a new connection that don't replace 
wrapped connection in linked table.
Linked tables start unconnected until the first access and remain connected for 
session's life.

So, what's lacking here is something that can detect connection lost,reconnect 
and renew waped connection , on internal methods of linked tables that make use 
of external conn. .

Would be an useful an elegant extension of this feature.
