The most obvious method is to loop and use listFind()
<cfset match = "no">
<cfloop index="i" list="#list1#">
<cfif listFind(list2,i)>
<cfset match = "yes">
<cfbreak>
</cfif>
</cfloop>

Subject: Most efficient way to check if two lists
Hello,
Need to find out which way is the most efficient way to see if a value
in
list A is a value in list B.
List A = 1,2,3 VALID ListMatch
List B = 2,3,4
List A = 1,2,3 VALID ListMatch
List B = 1,4,6
List A = 1,2,3 NOT VALID ListMatch
List B = 7,4,6
As long as it has single matching values it is valid.
