Parameters
 
Parameter      Description
list A list or a variable that contains one.
value An element or a list of elements.
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 uses only the first
  character.
 
Usage
ColdFusion inserts a delimiter character before value.
To add an element to the beginning or end of a list, Macromedia recommends that you do so with code such as the following, rather than with the ListAppend or ListPrepend functions:
<cfset MyValue = "another element">
<cfif listLen(myList) is 0>
   <cfset myList = MyValue>
<cfelse>
   <cfset myList = myList & ", " & MyValue>
</cfif>
The following table shows examples of ListAppend processing:
Statement Output Comment
ListAppend('elem1,elem2', '' )
elem1,elem2, Appended element is empty; delimiter is last character in list; list length is 2
ListAppend('', 'elem1,elem2' ) elem1,elem2 List length is 2
ListAppend ("one___two", "three", "___") "one___two_three" Inserted the first character of delimiters before "three."

SELECT PARKNAME,CITY,STATE
FROM PARKS WHERE PARKNAME LIKE `AL%'
</cfquery>
<cfset temp = ValueList(GetParkInfo.ParkName)>
<cfoutput>
<p>The original list: #temp#
</cfoutput>
<!--- now, append a park name to the list --->
<cfset temp2 = ListAppend(Temp, "ANOTHER PARK")>
