As I said - I'd rather not have to do this many nextval calls. Also, there is a problem - I can not guarantee that the numbers are sequential by this method. Someone else can get in and make a sequencer call at the same time. I could lock them out - but then with this many calls - they might time-out and fail waiting for me. Not a good alternative, particularly since this probably an active database where there might be 100's of end users needing to enter and manipulate data at the same time. (BTW the number I cite is just illustrative - I have run tests up to 4,000,000 objects and expect the end user to do more than that).

This method of course occured to me (its the obvious method) - but has the two problems I mentioned. Its slow and it does not guarantee sequentially - thus doesn't solve all the problems. I'm vying with my manager to force the end user to have privilege to alter the sequences, but he wants me to find out if there is an other way to do this first.

And I should add I can not redesign the database. We are writing data import/export utility for an existing widely used database application product - and must live in constraints of that product's design.
