Nz problem in select query

[Wayne Jordan]

I have a problem that involves null values that I do not know how to solve.
I have the following tables:


tblOrderDetailsKeyItemIdOrder QtyPO#001A204001002B204001003C304001

tblTransactionsKeyTransDateItemIDReceivedPO#0011/1/2014A1040010021/2/2014B2040010031/3/2014A54001

I also have a table that list the items and on that table the column ItemID is the key.
I want to create a query that will list all items ordered on a PO# and how many have been received so far. With that I will calculate the outstanding qty. I want to see:

qryOutstandingPOPO#Item IDOrder QtyReceivedOutstanding4001A201554001B202004001C30030

But all I see is this:


qryOutstandingPOPO#Item IDOrder QtyReceivedOutstanding4001A201554001B20200
It is missing item C because I have not received any yet so there are no records in the Transactions table for it to select. I don’t know how to fix it. I believe the answer has something to do with Nz but I can’t figure it out. :banghead:I don’t know VBA so I do all of my queries in Query Design. The truth is I know enough to get myself in trouble.
Thank you very much to anyone who can help.

Those tables were done in a spreadsheet for this post and they didn't look like that in excel. Let me type them out.

tblOrderDetails
Key ItemId OrderQty PO#
001 A 20 4001
002 B 20 4001
003 C 20 4001

tblTransactions
Key TransDate ItemID Received PO#
001 10/12/2014 A 10 4001
002 10/12/2014 B 20 4001
003 10/13/2014 A 5 4001

What I want to see is this:
PO# ItemID OrderQty Received Outstanding
4001 A 20 15 5
4001 B 20 20 0
4001 C 20 0 20

What I get is this:
PO# ItemID OrderQty Received Outstanding
4001 A 20 15 5
4001 B 20 20 0

Sorry about freaky looking tables in first post.

I'm not going to be able to help very much as I no longer have Access but you need to look at joins, particularly outer joins. You want to select all records from one table and matching items from the other.

Thank you very much. I rebuilt the query and made sure all the data came from tblOrderDetails and just asked for a sum of the qty Received from tblTransactions. Then I switched to SQL mode and changed the word INNER JOIN to LEFT JOIN and it gave me all I asked for but NULL for the Items that I had not received. I changed the field name in the query from Received to Nz(Received) and that changed the nulls to zeros.

Glad you got it sorted.
Note that you can change the Join in Design view by clicking on the join line , a menu appears offering options. Can't remember if it's left or right click as I used to do it automatically.
