Thanks for answer Miles, I'm aware of what you wrote but have a little hope to find some way, and Robby what I'm trying to do is avoid the user for update or delete a record that other user has been already selected, so I cant tell something like: "This record is locked by another user, try later", currently I'm doing this by code but like to do by Postgres directly. Thanks in advance. ----- Original Message ----- From: "Robby Russell" <robby@xxxxxxxxxxxxxxx> To: "Norma Ramirez" <norma.ramirez@xxxxxxxxxxxxxxxx> Cc: <php-db@xxxxxxxxxxxxx> Sent: Friday, August 13, 2004 10:07 AM Subject: Re: Lock Record on Postgresql -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
