James, in which cases is it not 100% reliable? Are the CF-Talk archives searchable?
Ryan, your method seems ideal... but I think it would take me a month to do it... what DB datatype is your UUID? Cheers, Baz -----Original Message----- From: Ryan Guill [mailto:[EMAIL PROTECTED] Sent: Sunday, January 08, 2006 8:08 PM To: CF-Talk Subject: Re: Get last inserted ID What I usually do is have a column that just holds a specific timestamp or uuid of some sorts. I create a variable to hold the timestamp or uuid right before the insert query, then I select against the table looking for that timestamp or uuid. If you are using a db that stores a pretty detailed timestamp, especially down to the millisecond (not sure how mysql does it), that would work very well. And if you can use a uuid for the primary key instead of an autonumber, then you will have the id before you enven to the insert statement. Just some ideas.
