Adding 1 week to a timestamp, which can be NULL or expired
Started by Alexander Farberover 14 years ago2 messagesgeneral
Hello,
I'm trying to add 1 week "VIP-status" to all users in a table:
update pref_users set vip = max(vip, now()) + interval '1 week';
but max() doesn't work with timestamps.
Is there maybe still a way to solve it with a one-liner?
Thank you
Alex

max works fine with timestamps... however, its a 1 argument function
that takes an aggregate as its argument.
you perhaps want GREATEST(val1,val2)
update pref_users set vip = greatest(vip, now()) + interval '1 week';
