I have a table (x,y,z) - I'd like to take the rows with unique x values - but, when more than one row have the same x value, I want the one with the minimal z value.
How can I do that? I can imagine doing it with window functions, but also that regular SQL should be able to do it too. -- Sent via pgsql-general mailing list (pgsql-general@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
