Hello,
I have the following query/result:
auction=# select max(b.lot) as quantity,max(b.price) as price,p.login from bid b, person p where b.auction_id = 84 and
p.id= b.person_id group by p.login order by max(price);quantity | price | login
----------+-------+----------- 1 | 5000 | papy 12 | 5750 | cunctator 8 | 6000 | vindex
(3 rows)
Now I would like to sum() all results from the quantity column and
return it with one SELECT statement. Is that possible?
I am trying:
auction=# select sum(b.lot) from bid b, person p where b.auction_id = 84 and p.id = b.person_id ;sum
----- 52
(1 row)
But this is wrong because it sums all quantities. I don't know how to
apply a valid WHERE clause in that case.
Thanks in advance for any help, cheers,
