What I would like to do is simply get the last date_sent and it's
status for every broadcast. I can't do a GROUP BY because I can't put
an aggregate on the status column.
SELECT MAX(date_sent), status
FROM broadcast_history
GROUP BY broadcast_id
You could try the following:
select status
from broadcast_history bh
where bh.date_sent =
(select max(bh2.date_sent)
from broadcast_history bh2);
This reminds me of an interview question: I was asked how to get a
maximum column from a table without using max. How would you do that?
Thanks,
Yasir
