The example you've presented is little different
from asking NorthWind to list the customers
who placed orders on a particular date. The fact
that your date field contains both date and time
information comes into play only if you're including
time criteria in your query.
Try copying/pasting this to a new query in NorthWind,
then run the query. It's fairly forgiving - when it asks
for a date, you can type 08/11/94, 8/11/94, 8 Aug 94,
08-Aug-94, and you should get a response.
Once you have this up and running, you can adapt
it to your particular situation.
PARAMETERS [enter order date] DateTime;
SELECT Customers.CompanyName, Orders.OrderID, Orders.OrderDate
FROM Customers INNER JOIN Orders ON Customers.CustomerID = Orders.CustomerID
WHERE (((Orders.OrderDate)=[enter order date]));
