I hit this issue regularly but here is an example….

I have a Order and Delivery Tables. Each order can have one to many Deliveries.

I need to report totals based on the Order Table but also show deliveries line by line.

I can write the SQL and associated Access Report for this with ease ….

SELECT xxx 
    FROM 
        Order 
    LEFT OUTER JOIN 
        Delivery on Delivery.OrderNO = Order.OrderNo

until I get to the summing element. I obviously only want to sum each Order once, not the 1-many times there are deliveries for that order.

e.g. The SQL might return the following based on 2 Orders (ignore the banalness of the report, this is very much simplified)
Region  OrderNo    Value    Delivery Date
North   1          £100     12-04-2012
North   1          £100     14-04-2012
North   2          £73      01-05-2012
North   2          £73      03-05-2012
North   2          £73      07-05-2012
South   3          £50      23-04-2012

I would want to report:

Total Sales North - £173
    Delivery 12-04-2012
    Delivery 14-04-2012
    Delivery 01-05-2012
    Delivery 03-05-2012
    Delivery 07-05-2012

Total Sales South - £50
    Delivery 23-04-2012

The bit I’m referring to is the calculation of the £173 and £50 which the first of which obviously shouldn’t be £419!

In the past I’ve used things like MAX (for a given Order) but that seems like a fudge.

Surely there must be a regular answer to this seemingly common problem but I can’t find one.

I don’t necessarily need the code – just a helpful point in the right direction.

Many thanks,

Chris.

    A roll up operator may not look pretty. However, it would do the regular aggregates that you see now, and it show the subtotals of the order. This is what you’re looking for.

    SELECT xxx 
    FROM 
        Order 
    LEFT OUTER JOIN 
        Delivery on Delivery.OrderNO = Order.OrderNo
GROUP BY xxx
WITH ROLLUP;

    I’m not exactly sure how the rest of your query is set up, but it would look something like this:

    Region  OrderNo    Value    Delivery Date
North   1          £100     12-04-2012
North   1          £100     14-04-2012
North   2          £73      01-05-2012
North   2          £73      03-05-2012
North   2          £73      07-05-2012
NULL    NULL       f419     NULL
