Cached Query

Two suggestions: first remove the dbtype attribute. There is no reason for it. Secondly, the variable application.admin_query_cache_time might have something to do with your problem.

How is the variable application.admin_query_cache_time defined? What datatype is it?

The following should help you solve the problem completely:

<cftry>

<cfquery  name="NumLogins" datasource="#application.datasource#" dbtype="ODBC"  cachedwithin="#application.admin_query_cache_time#">
select login_id from logins where company_id = #company_id# and company_login_id = #company_login_id#
</cfquery>

Number of Logins: <cfoutput>#NumLogins.recordcount#</cfoutput>

<cfcatch type="any">

<cfdump var="#cfcatch#">

</cfcatch>

</cftry>

Not sure if it's the cause of your problem, but I've had horrible luck with trying to assign cache timespans to variables and getting them to work.  I always seem to have to hard code a createtimespan() value into a cachedwithin().  Maybe you're trying to read from a cached query that isn't there.

Please check whether the variable is defined before display using IsDefined()
