Just recently post a problem on how can i see all max(dateposted) on
all of my records by doing this..
select datacount,office,filename,status, max(dateposted) from dCOPY
group by office;
now, i was wondering if i can use max() on update to update all my
current records only..
i tried this:
mysql update dCOPY set status = '1' where dateposted = max(dateposted);
ERROR : Invalid use of group function

not working.. :(
o btw.. i just opened another email topic, so it will be divided by

Hi!
That method will not work. InnoDB must be quiet long enough so that it has
time to flush all the contents of the buffer pool to the data files.

I'll try to explain correctly my idea.
I need to develop a on-line sale's website. For that, I have some dough's on how to
create the table basket.

- IDclie (PK)
- ...
Produts
- IDprod (PK)
- ...
Basket
- IDbask (PK)
- IDprod (FK)
- IDClie (FK)
- qt
- date
Sale
-
If you want to know how many sales were made to a give client (e.g. where IDclie =
99), this should see you right:
SELECT count(*)
FROM Sale, Basket
WHERE Sale.idbask = Basket.IDbask
AND Basket.IDClie = 99
