Hello, I have 2 tables: In one I log the user name of a web site user like this: Name Access time "makost0001" " 2007-04-19 15:09:19" "makost0001" " 2007-04-19 15:09:19" In the other I have the user name his group and the expiry date of his account. Name Group Expiry date "makost0001" "book" "2013-04-05 09:41:25.357677" When the user accesses the web site for the first time I need to change the expiry date to < today > + 3 years. Problem is I need to do this on a regular basis once a day to avoid table locks. And also how do I tell the program to find the earliest access time of a user? Like shown above there a multiple entries for the same time & user because of the multiple requests. :o( Should I have a field in the first table like <ignore this entry forever> when an expiry date is already set? I'm pretty new to db programming and especially to PostgreSQL. Can somebody please help? Cheers, Pete
