returning a struct of queries - coldfusion

Question

If a series of queries are created like so:
<cfloop list="#platform_list#" index="x">
<cfquery name="#trim(x)#" dbtype="query">
<!--- stuff to build the query --->
</cfquery>
</cfloop>
and I then return the queries in a struct like so:
<cfset queries_RET = StructNew() />
<cfloop list="#platform_list#" index="x">
<cfif StructKeyExists(args, #trim(x)#)>
<!--- here's where I think things go horribly wrong --->
<cfset queries_RET[x] = #x# />
</cfif>
</cfloop>
<cfreturn queries_RET />
And then when returned to the calling function as "graphData", I try to access it like so:
<cfloop list="#platform_list#" index="x">
<cfif StructKeyExists(url, x) and StructKeyExists(graphData, x)>
<cfloop query="graphData[x]">
I get an error at the last line:
Attribute validation error for tag cfloop.
The value of the attribute query, which is currently graphData[x], is invalid.
The value of the struct at graphData[x] is a string having the same value as the element name... so what do I do to assign the query with that name instead? I'm sure it's ridiculously obvious. :(
EDIT:
I'll give the answer to Shawn, although I finally figured out what my underlying issue(s) are. First, I didn't realize that
<cfset queries_RET[x] = #x# />
doesn't actually assign the query to the element at x, but instead a reference to it. To assign the actual query object, I need to do this:
<cfset queries_RET[x] = #Evaluate(x)# />
Second, when the struct is returned to the calling function, calling
<cfloop list="#Application.platform_list#" index="x">
<cfloop query="#graphData[x]#">
didn't work because the query attribute of cfloop is looking for a reference to a query object --- and the query object it was looking for didn't exist since it hadn't been returned.
Finally, now that I am actually returning a valid query object, that query attribute still doesn't work, because now graphData[x] isn't a reference. To make it work, I have to first assign a reference, and use that as the query attribute in the cfloop:
<cfloop list="#Application.platform_list#" index="x">
<cfset thisQuery = #graphData[x]#>
<cfloop query="thisQuery">
I think that my fundamental problem was not understanding the the query attribute isn't an actual query object, but a reference to one instead. It's been a learning curve!

Answer 1

Try
<cfloop list="#platform_list#" index="x">
<cfif StructKeyExists(url, x) and StructKeyExists(graphData, url[x])>
<cfset q = graphData[x]>
<cfloop query="q">
If this throws
The value of the attribute query, which is currently q, is invalid
Then you should cfdump the q make sure it is a query object.

Answer 2

The <CFLOOP> query attribute takes the name of a query (string), not an actual query object.
When you pass something into that attribute, CF expects it to be a string.
If it's a literal, CF will expect it to be the name of a valid query.
If it's a variable, CF will expect the value of the variable to be equal to the name of the query.
Therefore, the output you ultimately want is:
<cfloop list="#platform_list#" index="x">
<cfloop query="#x#">
Here is a full snippet of code that confirms this, which you may refer to/compare to for your own code:
<cfset query_a = QueryNew('id,name,pass') />
<cfset QueryAddRow(query_a)>
<cfset QuerySetCell(query_a,'id',1)>
<cfset QuerySetCell(query_a,'name','joe')>
<cfset QuerySetCell(query_a,'pass','joe123')>
<cfset query_b = QueryNew('id,name,pass') />
<cfset QueryAddRow(query_b)>
<cfset QuerySetCell(query_b,'id',4)>
<cfset QuerySetCell(query_b,'name','pete')>
<cfset QuerySetCell(query_b,'pass','pete123')>
<cfset query_c = QueryNew('id,name,pass') />
<cfset QueryAddRow(query_c)>
<cfset QuerySetCell(query_c,'id',7)>
<cfset QuerySetCell(query_c,'name','frank')>
<cfset QuerySetCell(query_c,'pass','frank123')>
<cfset platform_list = 'query_a,query_b,query_c' />
<cfloop list="#platform_list#" index="x">
<cfloop query="#x#">
<cfoutput>#id# #name# #pass#</cfoutput><br/>
</cfloop>
</cfloop>
You'll notice in this snippet that if you change the query attribute back to "x" (rather than #x#) you'll produce the exact same error you are encountering now.
Why?
Answer: platform_list is a comma-delimited list of strings (which x becomes via the loop), not a comma-delimited list of Query objects.
