Hi
Any help appreciated - I have spent 2 days trying to get this query to
work!
I have an orders database and a customer database.
The orders database has a date field for each order.
Because I want to obtain a monthly breakdown, I created a view called
monthcustomer as this select:
[EMAIL PROTECTED] writes:
> select distinct year,month,
> (select sum(monthcustomer.number_of_items) from monthcustomer where
> monthcustomer.year=m.year and monthcustomer.month=m.month) as NumPots
> from monthcustomer m;
> This goes off and never comes back -
