I am developing a database which will carry customers
billing information.
There are 2 tables: Customers and Orders

I need to run a query that will tell me the number of
outstanding debts and the amounts each customer has. I
know how to get the total amount of outstanding debts
using a calculated field [total]-[payments].

What i want the next query to do is to count the total
nubmer of calculated fields (as above) that are over 0 -
this field will tell me how many unpaid orders each
custoemr has. Ie. they have "x" number of outstanding
payments.

thanks.
 
Hi Sophie,

You can use a GroupBy query that has for the WHERE clause where whatever
the field is > 0.

Then use Count for whatever column.

You can type the calcuation into the Field row of a query, i.e.:
[total]-[payments]

In the Criteria row under this calculated field, enter:
Is Null Or <> 0
to retrieve those without a zero balance.
