Access 2007 Query to show all master records even when no activity

Last Modified: 2014-08-26
I have a basic query with 2 tables.

Table A
Name | Description

Table B
Name | Date | Quantity

I need a list of all descriptions in Table A with a Total Quantity from Table B

What I get is a list of all records from Table A that have activity in Table B, but I need to see ALL records in Table A and just assign a 0 to the ones that don't have anything in table B.

I have a right join on Name, so that's not the issue, any ideas how I can get all records from Table A?

Something like this ?
SELECT TableA.Description,
       Sum(TableB.Quantity) AS SumOfQuantity
  FROM TableA
    ON TableA.Name2 = TableB.Name2
 GROUP BY TableA.Description, TableA.Name2;

Open in new window

note: "name" is a reserved word, so using "name2".

I made several queries -- a Totals query to add up the quantities, one showing clients with purchases, and one showing those without purchases, and a union query to join them.

BTW, if you really have fields called Name and Date, that is not a good idea, since they are reserved names.  Also, it is best to join on a unique ID, such as an AutoNumber ClientID field (but I used ClientName in case you have to work with that field).

Here is a screen shot of the queries:

I wish it was that easy.  I have done exactly that and I still just get the records with activity.  Any other ideas?

Did you try mine?  It is more complicated, but does include the clients with no purchases.

Huh?.... seems the query shows all values from Table A in my example.  I must be misunderstanding something.
Couple things to consider ... are there any 'rules' for data on your tables ?
Maybe the IIF function can be useful;
    iif ( condition, value_if_true, value_if_false )

I'll attach the test db if you care to look at the results I'm seeing ... you have me curious.

I see where Helen is going with the Union query ... wondering if a straightforward join will work.

It is much simpler. Just use Nz() and one query:

    Nz(Sum([TableB]![Quantity]), 0) AS TotalQuantity
    TableB ON
        [TableA].[Name] = [TableB].[Name]

Thanks for the help everyone.  The Nz didn't work and just adjusting the join wouldn't do it.

I ended up doing the union query to make it work.
