Parameter

Description

list

A list or a variable that contains a list.

delimiters

A string or a variable that contains one. Character(s) that separate list elements. Default: comma.

If this parameter contains more than one character, ColdFusion processes each occurrence of each character as a delimiter.

ColdFusion ignores empty list elements; thus, the list "a,b,c,,,d" has four elements.

<h3>ListFirst Example</h3>
<!--- Find a list of users who wrote messages --->
<cfquery name = "GetMessageUser" datasource = "cfsnippets">
   SELECT Username, Subject, Posted
   FROM  Messages
</cfquery>

<cfset temp = ValueList(GetMessageUser.Username)>
<p>Before editing the list, it is:&nbsp;
<cfoutput>#ValueList(GetMessageUser.Username)#</cfoutput>. 
<p>(Users who posted more than once are listed more than once.)
<!--- Show the first user in the list --->
<p>The first user in the list is: 
<cfoutput>#ListFirst(temp)#</cfoutput>
<p>The rest of the list is:&nbsp;<cfoutput>#ListRest(temp)#</cfoutput>.
<p>(Users who posted more than once are listed more than once.)
<p>The last user in the list is: <cfoutput>#ListLast(temp)#</cfoutput>
