What I would like to do is run a SELECT query that will display each of the Inventory columns, plus an additional column AS TotalSold which is equal to the sum of the total units sold for each row of the inventory. My ouput would look like this:

Table Inventory
CUSIP     PurchDate OrigUnits OrigPrice TotalSold
74112E109 08/05/08     15,068    3.3025     9,315
816288104 08/08/07     50,300  0.772499         0
04648X107 10/08/08    200,000     1.485   200,000
04648X107 10/09/08    200,000      1.25   150,000
023164106 12/14/00     16,500      0.58         0
023164106 06/05/03    206,786  0.723998         0
023164106 06/05/03    280,896    0.7241         0


From the Sales table, I've been able to put together a query that will give me the TotalSold.

SELECT Sales.PurchDate, Sales.CUSIP, Sum(Sales.UnitsSold) AS TotalSold
FROM Sales
GROUP BY Sales.PurchDate, Sales.CUSIP;

I'm struggling with finding a way to get the output I'm looking for though.

All you need now is to join the 'Inventory' table with  your query. 3eyes

Excellent, that worked. What does LEFT JOIN do? How is that different than a normal join? In the past, when I wanted to join two tables, I would list them both after FROM (e.g., FROM Inventory I, Sales S)

Thanks.

I see, thank you for the article. This will be good to know in the future.
