Hello,
I am trying to return the most recently updated record from a table:
SELECT max(stopdate) FROM auction;
and this works but only returns the timestamp, however if I try to get
another column with the aggregate it fails:
SELECT title,max(stopdate) FROM auction;
ERROR: Attribute auction.title must be GROUPed or used in an aggregate function
Ok, so I group it now:
SELECT title,max(stopdate) FROM auction GROUP BY title; title | max
---------------+------------------------dfsdfsdf | 2000-07-10 05:00:00+02dssdfsdfsdfsf | 2000-07-09
16:00:00+02sdfsdfsdfsdf | 2001-04-10 15:00:00+02
(3 rows)
But the problem is that I now get three rows when I only want the max()
item.
How should I do it?
Thanks in advance,
