Changing the field names in a CFQUERY object

Question

Hello, I wonder whether you know the answer to this?
I want to change the names of the fields in a CFQUERY result
set after I have retrieved the results from the database (ie. I
can't use "AS" in the original SQL statement). I can think of 2
ways to do this - use the query-a-query (CFSQL) feature or just
build and populate a new query object, as set out below:
<cfquery name="CustList" datasource="name">
SELECT CustId,CustName,CustAddress FROM Customers
WHERE OrderStatus='P'
</cfquery>
OPTION#1:
<cfqueryname="GenericList" type="query">
SELECT CustId AS Id,CustName AS Name,CustAddress AS Address
FROM CustList
</cfquery>
OPTION#2:
<cfset GenericList = QueryNew("Id,Name,Address")>
<cfloop query="CustList">
<cfset unused = QueryAddRow(GenericList)>
<cfset unused =
QuerySetCell(GenericList,"Id",CustList.CustId)>
<cfset unused =
QuerySetCell(GenericList,"Name",CustList.CustName)>
<cfset unused =
QuerySetCell(GenericList,"Address",CustList.CustAddress)>
</cfloop>
Do you know which of these would be more efficient? And is
there a better way, whereby I can maniplulate the names of the
columns in the original query (ie. so that I can rename the
"CustName" field to "Name" and then use "CustList.Name" directly)?
Thanks!

Thanks guys!
If there is a close to zero overhead to the simple
query-a-query then that seems like the way to go, with no need to
look for a means of manipulating or modifying the original query.
The reason I want to change the field names is so that the
rest of my code can contain references to "CustList.Name" whereas
otherwise I would have to do something like
"Evaluate('CustList.#NameField#')" which is horribly messy. And the
way the original query is generated means I can't use "AS" in it,
but I still want to use the same code to work with that query
result and other query results that share similar/related data with
different field names.
