Railo has exactly this setting. You can either let Railo scan all scopes
like CFML, or for example the variables scope only. In addition in Railo
you can turn off implicit query scanning as well. So you would recieve
an error when you execute the following:
<cfquery name="getAddresses" ...>
SELECT name, firstname from addresses
</cfquery>
<cfoutput query="getAddresses">
name: #firstname# #name#
</cfquery>
My two notes on this. Not only is scoping variables easier to use, it is
much more performant. Just imagine you would use a variable from the
client scope without scoping it. CF would need to scan through 8 other
scopes first in order to find it first.
So to round up the example before just use:
<cfoutput query="getAddresses">
name: #getAddresses.firstname# #getAddresses.name#
</cfquery>
