Hello,
Is correct to do something like?:
SELECT row1,row2 FROM mytable
WHERE (row1,row3) IN
(SELECT row1 as p1,MAX(row3) as p2 FROM mytable
WHERE row3 <= current_date
GROUP BY row1)
I mean, I don't see documentation about subselects returning more than
one column, but it seems to work...
Thanks,
Francesc.
