if you're calling no-joy after implementing PL/SQL

If I'm tracking correctly I can say the java implementation of CopyManager is, to me, blindingly fast. So if the E and the T are in java then certainly the L can be also. I have not compared it to straight file-base copy because my data is conceived in Java and slammed home directly from the app (middle-ware). I write relatively large blocks (millions of records) to naked temporary tables and then let straight sql read from there and insert into final tables in chunks.
