Assuming you can have multiple records per day per machine (e.g. you're
polling for information throughout the day), the following holds. However,
the output doesn't provide for a separate column per day, but rather you get
a separate row for each day/machine combination.
Attached is a file that demonstrates the behavior I think you would like. But
basically, here is the SQL statement you're looking for:
SELECT Datestamp, Machine, SUM(Withdrawls)
FROM WithdrawlsTable
GROUP BY Machine, Datestamp
ORDER BY Datestamp, Machine;
