Hello,
I have a query like this: - SELECT jos_vm_orders.user_id, jos_vm_orders.cdate, sum( order_total ) AS total, count( jos_vm_orders.order_id ) AS ordercount, jos_vm_user_info.first_name, jos_vm_user_info.last_name, jos_vm_user_info.phone_1, jos_vm_user_info.user_email, jos_vm_user_info.city
-
FROM jos_vm_orders
-
LEFT JOIN jos_vm_user_info ON jos_vm_orders.user_id = jos_vm_user_info.user_id
-
WHERE jos_vm_orders.order_status = 'C'
-
GROUP BY jos_vm_orders.user_id
-
LIMIT 0 , 30
When there is more than one order for same user_id the script selects the first order cdate, but I would like to select the last one. Any ideas?

This actually an illegal query except MySQL uses an algorithm to 'guess' the fields you require where you haven't used an aggregate or a GROUP BY.
So jos_vm_orders.c date, jos_vm_user_inf o.first_name, jos_vm_user_inf o.last_name, jos_vm_user_inf o.phone_1, jos_vm_user_inf o.user_email, jos_vm_user_inf o.city are all chosen for you.
To specify the last date you could try
MAX() or use HAVING.
Well all other information for one user_id ir the same, but the cdate differs. Thank you very much for MAX(), this solved my probled because date is stored in timestamp format.

My code works perfectly 100% when adding items to my ArrayList and updating the listbox.
Works perfectly when deleting an item in the ArrayList when it is not the last entry but if it is

Funny thing is the SelectedIndex Changed routine fires off perfectly and then crash after the return

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.
