Hello,
I am trying to use SELECT DISTINCT ON. This works as intended:
SELECT DISTINCT ON (f1) * from table ORDER BY f1
f1 | f2 | f3
----+----+----
1 | 2 | 3
2 | 2 | 2
3 | 1 | 2
However, I am trying to order the results by non-distinct fields f2, f3
to get:
f1 | f2 | f3
----+----+----
3 | 1 | 2
2 | 2 | 2
1 | 2 | 3
Clearly this does not work:
SELECT DISTINCT ON (f1) * from table ORDER BY f2, f3, f1
So is there some other way without SELECT INTO a temporary table?
Thanks in advance.
Dave
