Left Join doesn't display the records I expected.

[Aldred]

Hi all,
I have a SQL query with all left joins. However, the left most table tClient wasn't displayed if it gets null from the right table.

The linking is something like tClient --> tPOin --> tPOItems --> tDelivered

The query is exactly like this:

SELECT EName, Sum(tPOItems.Charge*tDelivered.DQuantity) AS Amount 
FROM tClient left JOIN (tPOin left JOIN (tPOItems left JOIN tDelivered ON tPOItems.ID=tDelivered.POItemsID) ON tPOin.ID=tPOItems.POinID) ON tPOin.ClientID=tClient.ID WHERE InvoiceID Is Not Null And CalcMonth=Forms!fGenMonthlyStatement.bCalcMonth And CalcYear=Forms!fGenMonthlyStatement.bCalcYear 
GROUP BY tClient.EName;

The result is, for example:

Company A, $68012
Company C, $133000

However, I'd like to have Company B displayed but it doesn't.

Can someone please help me.

Thanks in advance.

My guess would be that it is related to the:

WHERE InvoiceID Is Not Null

Have company B placed any orders?

Try removing the grouping function SUM, and just display all the interesting columns.

Then, when you've massaged the querty to give you the desired records, then you can re-implement the grouping SUM.

Cheers!
