You need to use a join. Specifically, a left outer join. I won't
explain this in great detail; figuring out how this works can be your
research topic ;) but try this:
select a.id, a.from, a.to, a.message, a.insertdate, b.insertdate
from messages as a
left outer join messages as b on a.id = b.id
where a.status='SENT';

Hi,
I have a table which stores log traffic. The table contains these
fields:
transaction_id, from, to, message, status, insertdate
For example there is a message from A send to B, when the message sent
to B it will insert new record. And when the message is read by B, it
will also insert new record.
So the records should be something like this:
transaction_id, from, to, message, status, insertdate
20081224001, A, B, stest, SENT, 2008-12-24 01:01:01
20081224001, A, B, NULL, READ, 2008-12-24 01:01:03
My question is if I want to lookup 20081224001 and expect the result to
be like this:
transaction id, from, to, message, sent, received
20081224001, A, B, stest, 2008-12-24 01:01:01, 2008-12-24 01:01:03
How to build the query then? Please help and TIA.
