Cold Fusion lang question

Hi,
I have this statement which checks to see if anything exists in the  url field.

<cfif len(associate.url)>
## Field has a value in it
</cfif>

How would I check to see if the field IS NOT populated
This:
<cfif ! len(associate.url)>

or
<cfif not len(assicate.url)>

Neither? Both? Something else?
Thanks!

gdemariaCommented:
<cfif not len(assicate.url)>  -- field has no size

or you can just do..

<cfif  len(assicate.url) eq 0>  --- field is empty


I prefer the above, but you can also test to see if its equal to an empty string

<cfif  assicate.url  is "">
0

Any of the above, incuding gdemaria's example.  They should all do the same thing. So it's a matter of personal preference.

One other thing that may or may not apply here ... if you want to ignore extra white space, like "(space)" or "(multiple spaces)" , trim() the values first.  ie

        <cfif !len(trim(associate.url))>
