Using SSRS With An ODBC Data Source (Oracle RDB)

I'm attempting to use SSRS (2005) with my Oracle RDB database (old DEC RDB), using an ODBC driver. I am able to create a report, and view data, but I need to add some report parameters to filter the data. When I attempt to use parameters in the query, I either get a syntax error, or a message that my odbc connection cannot use "named" parameters, and that I should use "unnamed" parameters.

Here is a snippet of my sql query:

SELECT Application_Notes.Lease_Application, Application_Notes.Followup_Code,

<...>
FROM
Application_Notes Join

<...>
WHERE
(Application_Notes.Tickler_date >= {ts '2008-02-08 00:00:00'} AND

Application_Notes.Tickler_Date < {ts '2008-02-09 00:00:00'} )


The "Tickler_Date" field is a binary date field. The above syntax is pulled from a Crystal Report, which I am considering moving over to SSRS. Ideally, I would like the user to enter a single RunDate parameter, and have the query do the following:

Where (Application_Notes.Tickler_Date >= @RunDate and
Application_Notes.Tickler_Date < (@RunDate + 1 day) )


If the user has to enter two dates, that will be fine, but I can't seem to get past the errors.


Thanks,


Paul
