Can you use DSUM in CFC query?

Question

I am trying to create a query that returns,
Today, MTD, and YTD columns.  It can be done in Access like this:
SELECT G.TranDate, G.Desc
, DSum("amount","GLTest","trandate =DateSerial(2009, 2, 1)") AS Today
, DSum("amount","GLTest","trandate >=DateSerial(2009, 2, 1) AND trandate <= DateSerial(2009, 2, 15)") AS MTD
, DSum("amount","GLTest","trandate >=DateSerial(2009, 1, 1) AND trandate <= DateSerial(2009, 2, 15)") AS YTD
, DSum("amount","GLTest","trandate =DateSerial(2008, 2, 1)") AS LY_Today
, DSum("amount","GLTest","trandate >=DateSerial(2008, 2, 1) AND trandate <= DateSerial(2008, 2, 15)") AS LY_MTD
, DSum("amount","GLTest","trandate >=DateSerial(2008, 1, 1) AND trandate <= DateSerial(2008, 2, 15)") AS LY_YTD
FROM GLTest AS G
WHERE (((G.[TranDate])=#2/15/2009#))
ORDER BY 1;
But, this is the result in an actual CFC test:
Error Executing Database Query. 
[Macromedia][SequeLink JDBC Driver][ODBC Socket][Microsoft]
[ODBC Microsoft Access Driver] Too few parameters. Expected 2. 
The error occurred in C:\Inetpub\wwwroot\Daily2006NoForms\CFCS\Test.cfc:

<cfquery>
SELECT glt_trandate, glt_desc, glt_amount
, DSUM("glt_amount", "GLTrans", "glt_trandate =#createODBCDate(toDate)#") AS MTD
FROM GLTrans
WHERE ((glt_trandate) = #createODBCDate(toDate)#)
</cfquery>
This is what is actually being sent.
SELECT glt_trandate, glt_desc, glt_amount
, DSUM("glt_amount", "GLTrans", "glt_trandate ={d '2009-12-02'}") AS MTD FROM GLTrans
WHERE ((glt_trandate) = {d '2009-12-02'})

I'll first-up concede that I have't used Access since I was at polytech.  So anything I offer up here is going to be vague, and based on recollections of reading about other people's problems with it.
I'd usually strum up an Access DB and have a mess around with it, but I don't have MS Office installed on this machine, and I can't be arsed downloading a trial of the thing just to sort out one query.  I'm sure you understand ;-)
Firstly, one recollection I have is that whilst the query tool in Access is quite forgiving of non-standard SQL, JDBC drivers are not.  One thing that could cause gyp is using double-quotes instead of single-quotes.  I know the Acces query tool will accept double quotes, but they're not actually valid in SQL.  So perhaps try single quotes instead.
Also I am really surprised that you have success using CF's "ODBC date format" - eg: {d '2009-12-02'} - when Access expects dates like this: #2/12/2009#.  I know this has not worked for people in the past.  I think just '2009-12-02' might work, but don't quote me on that.  Or just do it "properly" my using a <cfqueryparam> (which as I touched on, you should be doing as a matter of course anyhow).
That "Too few parameters" error Access spits out is a fairly ubiquitous one: it seems to be what it says whenever it sees an expression it doesn't understand.  So I would not put too much stock in that actually being the problem.
Have you tried taking the SQL that CF is passing to the driver, and running that straight in Access's query tool?  It might give a better error.
Of course no post about Access problems would be complete without the caveat that Access is not intended to be used as a server-based DB solution, it's a desktop app, so it's completely inappropriate to be used as a DB for a multi-user environment such as a website back-end.  So if there's any way you could possibly stop using Access and use a proper DB system, that would be the best thing to do: if, for example, you are only just starting the project and you would not take too much of a hit from swapping Access out.  It might not be an option, or it might be outwith your control, I guess.
