Found the answer at http://qnalist.com/questions/4082996/multi-row-inserts-and-last-insert-id:

Reply-Mime-Version: 1.0 I suspect the answer is that last_insert_id() is set only once perl INSERT query. In fact, it's documented as doing so: http://www.mysql.com/doc/M/i/Miscellaneous_functions.html So it's not a bug. :-) I don't see an easy way off the top of my head. Hopefully someone else has come up with a good work-around they're willing to share. Jeremy Jeremy D. Zawodny,
