Re: [MS_AccessPros] Query no longer returning results



I feel really stupid. The query is working just fine. I didn't scroll down far enough. I have a lot of part numbers in my inventory without any quantity on hand. I've added criteria now that eliminates parts without quantities.

I hope your day has gone better than mine has started. Thanks for waking me up!

When there is no matching row in the Totals query for a particular part number, you should get zero for OnHandExtension because OnHand will be Null.  Are you sure there are matching rows?

Hello Pros,

I created the following query this morning and it gave me the results I wanted. The I added it to another query and now it no longer gives me any values in the onhand field or the onhandextension field. The query qryQOH is a totals query. Here is the SQL of both:


SELECT [Part Stock].PRTNUM_06, Sum(Nz([QTYOH_06],0)) AS OnHand
FROM [Part Stock]
GROUP BY [Part Stock].PRTNUM_06;


SELECT [Part Master].PRTNUM_01, [Part Master].ONHAND_01, qryQOH.OnHand, ([Cost_01]/[cstcnv_01]) AS Cost, [Part Master].TYPE_01, [Part Master].BOMUOM_01, [Part Master].PMDES1_01, Round(Nz([onhand],0)*[cost],2) AS OnHandExtension
FROM [Part Master] LEFT JOIN qryQOH ON [Part Master].PRTNUM_01 = qryQOH.PRTNUM_06;

I don't have any clue why it stopped working.
