Hi Michael
I have some fairly basic code which is moving data from one DB to another.
I have trapped errors on inserts just in case there were unexpected
duplicates. When I go to commit this transaction, MySQL correctly throws
an IntegrityError exception: Duplicate Entry which I trap, and perform a
rollback. However, the rollback ALSO receives an IntegrityError exception
from MySQL for the same insert query??
