Try:
SELECT itemid, qty AS maxqty, DateStamp AS Mdate FROM mtrans WHERE qty
IN (SELECT Max(qty) AS MaxQty from mtrans AS mt where mt.itemid =
mtrans.itemid);
Of course, only use this query if the other poster's answer is
horribly wrong :-).

Hello,
I am importing data that lists rates for particular coverages for a

The table that I'm dealing with has just under 9M rows and I may need

Hello there,
In my asp.net page using VB, I have a date text field in mm/dd/yyyy

the date is greater than or equal to the current date. If not, I'd
like to display the error message to ValidationSummary.
It seems to make sense to me to use CompareValidator but the problem
is put the current date into CompareValidator. So, I created a hidden

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
