Thanks, I've heard that, but in this case won't exactly fit my needs...
..First, I'm working on a PostgreSQL 8.1.4 modification, and it would be really difficult to add all the changes I've made to the new version. ...Second, I need to do all this form the backend (Postgres Source Code). I can't use any User or Administrator defined functions or sometime like that. Well, maybe I didn't make myself clear, this is what I need to do: I need to know the values of some fields (columns) from the last inserted tuple. The problem is that I need to do this in the moment I'm inserting a new one (all from the backend code) and compare the values between the new one (N.O) and the all ready inserted (A.R.I), and if the N.O fits some properties (according to the A.R.I) it must be decided if it has to be finally inserted or not. I think there's not to much difficulty on that, but until now I haven't found how to access that information. I can reach the HeapTuple structure according the A.R.I tuple, but I don't know how to access the information (values for its attributes) stored on it. Thanks again... 2007/1/24, David Fetter <[EMAIL PROTECTED]>:

RETURNING. Perhaps you could use the 8.2 series instead :) Cheers, David. -- David Fetter <[EMAIL PROTECTED]> http://fetter.org/ phone: +1 415 235 3778 AIM: dfetter666 Skype: davidfetter Remember to vote!
