Building a session query from multiple queries of same name

Question

I have a SQL query that runs with the name="getcamp" multiple times within a page, then uses a template to display results.
The criteria is different on each run, but the data retrieved is exactly the same.
On another page I need all of the data, so I can loop over it as if it was one query. The idea is to pass the query to the other page in a name="session.getcamp" , so that the data from the query is stored in a session.
The issue I have is that there are the 5 queries with the same name in the first page. Could anybody tell me how I would merge each one into a session query that would have the one name session.getcamp but contain the results of all 5 queries
Thanks

I would suggest the following design:
1) Indeed use the session scope to store the part-queries. However, I would store each of them in the session scope, and union them only where a union is required. You thereby achieve more power and flexibility, as each of the queries will continue to be available to requests throughout the session.
2) I would use the duplicate function to avoid any further reference to the original query. Something like:
First query, name= "getCamp"
<cfset session.getCamp1 = duplicate(getCamp)>
Second query, name= "getCamp"
<cfset session.getCamp2 = duplicate(getCamp)>
etc., etc.
3) On the page where you need to merge the 5 queries:
<cfquery name="getCamp_merged" dbtype="query">
select * from session.getCamp1
union
select * from session.getCamp2
union
select * from session.getCamp3
union
select * from session.getCamp4
union
select * from session.getCamp5
</cfquery>
It's Sunday today, at least where I am. As far as CPU consumption is concerned, whether or not what I've suggested turns out to be the devil's work is up to you to find out.
