Question
Coldfusion <cfif isDefined -- I must have this setup incorrectly
I've got some logic to run or not run a query. If the query doesn't run then I don't want to show a block of cod below. I'm using the <cfif isDefined()> to test for the query. I must have this setup incorrect b/c I keep receiving the error message: Element not defined. (Element CLASS_ID is undefined in GETB.) Code below.
Thanks for help.

A cleaner way to do this is to move your code up into the same CFIF statement was the query
<cfif listFindNoCase(request.boA
<cfloop query="getBreak">
<cfquery dbtype="query" name="getB">
select class_id, breakout_id
from getBreak
WHERE breakout_id = '#getBreakouts.breakout_id
</cfquery>
</cfloop>
Hi <!===== MOVE IS UP HERE so it only runs if the query is run
</cfif>
Or, if there is a lot of code there, go ahead and run the query but ensure it returns no values. Then you don't have to test for it's existance, just for the value....
<cfloop query="getBreak">
<cfquery dbtype="query" name="getB">
select class_id, breakout_id
from getBreak
WHERE breakout_id = '#getBreakouts.breakout_id
<cfif listFindNoCase(request.boA
AND 1 = 2 -- make sure nothing is returned
</cfif>
</cfquery>
</cfloop>
Also, I suspect this is work in progress... but you are currently looping your query again and agagin without doing anything inside the loop. I suspect you're going to add some code before the </CFLOOP> ? Otherwise it's not worth looping... right?

check to see that this condition
<cfif listFindNoCase(request.boA
is being met.
the error message may actually be trying to tell you that getB is not defined ie: getB.class_id is not defined since getB isn't
