DSum in Query

[D]

In my query, I have a field: New_Cost:[AllocatedCost]+[Base]

I need to get the Total of that column and divide by each record [New_Cost]
to come up with a percentage in a new field -- New_Cost_Percentage.

Can this be done and if so, how?

 

[Michel Walsh]

SELECT itemID,
SUM(qty) AS totalForThisItem,
SUM(qty) / (SELECT SUM(qty) FROM myTable) AS percentage
FROM myTable
GROUP BY itemID


is an example about how you can do it (in SQL view of the query). change the
table name and the fields name (any thing which is not all cap), as
appropriate for your case.
