ListRest

Description

Gets a list, without its first element.

Return value

A copy of list, without the first element. If list has one element, returns an empty list.

Syntax

ListRest(list [, delimiters ])

Parameters

Parameter Description

list
A list or a variable that contains one.

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.

Parameter	Description
list	A list or a variable that contains one.
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.

Usage

If the list begins with one or more empty entries, this function drops them, as well as the first element.

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

<cfquery name = "GetMessageUser" datasource = "cfsnippets">
  SELECT Username, Subject, Posted
