RecordCount Error

Question

Can someone please look over this code and check for any
problems? I'm receiving the RECORDCOUNT is undefined error for the
following line:
<cfif GetStudentDetails.RecordCount eq 0>
Thanks!

<!--- Check the supplied Username and Password against the

<cfif GetStudentDetails.RecordCount eq 0>
<!---
If the query recordcount is zero, the username did not
exist. Send the user back to the login form
and show the appropriate error message.

Create the request scope structure to hold the user data.
Notice it is NOT necessary to first create the
request.User structure with StructNew(). Simply using dot
notation after the User portion will tell
ColdFusion the variable is a structure.

Answer 1

Here's my query:
<cfquery name="GetStudentDetails"
datasource="#request.datasource#">
SELECT STUDENTID, STUDENTLASTNAME, STUDENTFIRSTNAME,
STUDENTMIDDLENAME
FROM StudentClasses
WHERE STUDENTID = #FORM.Username#
</cfquery>
We have already moved the query up. :)
The error has changed from a record count error to a database
error:
Error Executing Database Query.
Data type mismatch in criteria expression.
