CFC Error on QoQ

Question

Error:
Error casting an object of type to an incompatible type. This usually indicates a programming error in Java, although it could also mean you have tried to use a foreign object in a different way than it was designed.
The error occurred in C:\Inetpub\wwwroot\RMS\Untitled-3.cfm: line 15

Answer 1

You can NOT mix QoQ and DB queries together...
this is QoQ
<cfquery dbtype="query" name="GetZone">
this is DB query
<cfquery name="GetZone#i#" datasource="#i#">
You will need to run your DB queries first (outside QoQ)
and then run the loop again to UNION all results...
<cfloop from="1" to ="#listlen(arguments.DSN)#" index="i">
   <cfquery name="GetZone#i#" datasource="#i#">
    SELECT ccflocationID, Location_Name
    FROM ccflocation
   </cfquery>
</cfloop>
<cfquery dbtype="query" name="GetZone">
select ccflocationID, Location_Name from myLoc
<cfloop from="1" to ="#listlen(arguments.DSN)#" index="i">
  union
select ccflocationID, Location_Name from GetZone#i#
</cfloop>
</cfquery>
