I'm currently using WebFOCUS at work and they have a LAST operator, referring to the value a column had in the last returned row. That's pretty good for stuff like this, so I wonder if it wouldn't be beneficial to have something like that in Postgres?
Already there since 8.4 ;) Look into the windowing functions (in Oracle they are called analytical functions) http://www.postgresql.org/docs/current/static/tutorial-window.html Thomas -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
