Hi all,
Could do with some help please.
I have a query that grabs details of items that have been ordered from
an ecommerce site. Order details are in "tracking" and ordered items in
"trackitem".
The query works fine and generates a row for each item, including bits
of info retrieved from other tables.
So the next thing I need to do is aggregate rows that are for the same
item, at the same price. I've looked at GROUP BY but can't figure out
how to get it to group rows with same product name and price, and
generate a column with the total of the number of aggregated rows in
each row.
Can someone please point me in the right direction?
My current query is below.
Thanks in advance.
Nigel
