Isn't it much more efficient to get all result for all the dates
in one query?
<ffset startdate = '2003-08-01'>
<cfset enddate = '2003-08-15'>
<cfquery name="countReserved" datasource="#datasource#">
SELECT dt.countDate, Count(rt.radios) as daycount
FROM (
SELECT <cfqueryparam type="cf_sql_date" value="0000-01-01"> AS
countdate
<cfloop condition="startdate LTE enddate">
UNION
SELECT <cfqueryparam type="cf_sql_date" value="#startdate#">
AS countdate
<cfset startdate = DateAdd("d",1,startdate)>
</cfloop>
) dt, reservedTable rt
WHERE rt.StartDate <= dt.countDate
AND rt.ReturnDate >= dt.countDate
GROUP BY dt.countDate
</cfquery>
