Question

I’m writing a web service in ColdFusion. The problem is that I cannot figure out how to get rid of the comma after the last element. My code looks like this:

<cfoutput query="Attachments">
    #url#,
</cfoutput>

Which produces output like this (notice the trailing comma)

url1,url2,url3, 

How can I get rid of the trailing comma and produce this instead?

url1,url2,url3

Answer 1

This is an easy method:

<cfoutput>#ValueList(Attachments.url)#</cfoutput>
