Help Designing a Query to Count Classes

Hello:

tblClasses
-----------

I thought designing this query would be easy, but it's turning out to be
harder than I anticipated. Obviously I'm doing something wrong.

We need to count the number of classes between 2 dates [Class_Date] field.
That's the easy part. Then we have to count the number of classes in each
category, based on the [Class_Status] field, that were

"Completed"
"Cancelled"
"Resecheduled"
"Cancelled - No Registrants"
"Cancelled - No Attendees"

The above are all of the possible choices for the [Class_Status] field. Can
someone please point me in the right direction.

Thanks

SELECT Class_Status, Count(Class_Status) as TheCount
FROM [ClassesTable]
WHERE Class_Date Between #1/1/2007# and #12/31/2008#
GROUP BY Class_Status

In design view
-- Add your table
-- Add Class_Status field TWICE and Class_Date field once
-- Select View: Totals from the Menu
-- Change GROUP by under one Class_Status field to COUNT
-- Change GROUP BY under Class_Date to WHERE
-- Enter date range criteria under Class_Date

Hi John:

Thanks for the prompt response. That query works as designed, it gives us
the total number of classes for each status. That's what we want, but there's
still a problem.

I can design a query that gives us the total number of classes during that
time frame. Or, I can design a query that gives us the total number of
classes for each status, which is the one you designed.

However, the part I cannot figure out is how to include the total number of
classes in the SAME query. In other words, take the query you designed and
also calculate the total number of ALL classes during that time frame.

Any suggestions?

Is this the kind of thing you are after?

Completed 15 72
Cancelled 18 72
Resecheduled 12 72
Cancelled - No Registrants 13 72
Cancelled - No Attendees 14 72

If this is the case, I think DSum would work.

Except for the fact that I only need the total once, that's exactly what we
need.

So I can use DSum to create a calculated field in the same query John
designed?

Thanks,
Robert

Calculated columns don't work like that unfortunately.

I would probably use a union query if there was some reason not to use a
calculated field in a report:

SELECT Class_Status, Count(Class_Status) as TheCount
FROM [ClassesTable]
WHERE Class_Date Between #1/1/2007# and #12/31/2008#
GROUP BY Class_Status
Union
SELECT 'All Classes' as Class_Status,
Count(*) as TheCount
FROM [ClassesTable]
WHERE Class_Date Between #1/1/2007# and #12/31/2008#

Now that's what I call creative thinking.
