When we do batch inserts, the rows are inserted in random order

How can we control to database insertion order?
- create eo
- insert in to ec
- after doing about 20 inserts, we do ec.saveChanges()
All rows are there in the database but the insertion order is random.
Can this be controlled? How?
Works fine when you save changes after every ec insert But that is
inefficient..
The order is undefined. Are you having problems with constraint
violation? Your best option is to make the constraints DEFERRABLE
INITIALLY DEFERRED if your database supports it. If not, Wonder's
ERXEntityDependencyOrderingDelegate is your next best choice.
