Yes. My question was not stated in terms of a dynamic query, but that is,
of course, what my interest is.

I hope this is so. If it is, then naming the query Request.MyQuery
eliminates the need for a LOT of locking downstream compared to naming the
cached query Application.MyQuery.
BTW, contrary to Alliare's Best Practices, I find for CF 4.01 the option of
naming a query Application.MyQuery instead of Request.MyQuery means you
need to use CFLOCK like so:
<CFLOCK NAME="Application.AppName" etc
<CFQUERY NAME="Application.MyQuery" etc
blah, blah
</CFQUERY>
</CFLOCK>
since the Duplicate function is not available in CF4.01.
And in this same example in Best Practices, shouldn't Allaire have had
<CFSET application.qUser = Duplicate(variables.qUser)> rather than
<CFSET application.qUser = variables.qUser>?
best, paul
