Pretty straightforward:

I have two different connections to two different databases, and I need to find the absolute fastest way to move the data from a table in connection 1 to an identical table in connection 2.  

I'm hoping I don't have to go row-by-row with a bajillion "UPDATE" calls to do this.

It's often easier to use the tools of the rdbms to do this but failing that you could use one update statement (PreparedStatement) in batch mode

But wouldn't the prepared statement require me to loop through the result set record-by-record still?  I was hoping for some sort of more direct "bulk" method.

Well that's how cursors work. Are you talking about Access by any chance?

Sure enough, using the RDBMS's "INSERT INTO" statement I was able to insert to an external database, and it was quite fast.
