DBI and primary keysby $code or die (Deacon)

$code or die has asked for the
wisdom of the Perl Monks concerning the following question:
Hi guys. I need some help! I've been at work now for 36 hours (seen the same people come and go twice already!) and I've been stumped on a problem for a bit.
I'm trying to insert a row into a database and pull out the ID (primary key) that the database assigned automatically. I'm using DBI, but I tried the AddNew() func in ADODB.Recordset but that was no joy. Back to DBI now.
My original thought was insert the data and do a "Select MAX" on the primary key, but could end up worse than the race conditions you get in bad file-locking practices.
I am sure that there must be a way of doing this in DBI, but I can't see how - execute() returns 1 always (almost always)
It's starting to do my head in! I read through the DBI docs again but couldn't find anything - neither on usenet nor on PM Super Search. Although this could be due to my almost delirious hyper-caffeinated state. The answer is probably staring me in the face. Oh, I tried DBIx::Recordset and didn't like it much although I suspect it "might" be able to do what I want (sorry Terrence).
I appreciate any help available. Here's a bit of code I've munged over the past few hours... (I know its not terribly efficient at this stage but I'll fix that once I figure out how to do this primary key thing):
Thank you guys
