SELECT FirstName, LastName FROM Employees
</cfquery>
<!--- create an array --->
<cfset myArray = ArrayNew(1)>
<!--- set element one to show where we are --->
<cfset myArray[1] = "Test Value">
<!--- loop through the query and append these names
successively to the last element --->
<cfloop query = "GetEmployeeNames">
   <cfset temp = ArrayAppend(myArray, "#FirstName# #LastName#")>
</cfloop>
<!--- show the resulting array as a list --->
<cfset myList = ArrayToList(myArray, ",")>
<!--- output the array as a list --->
<cfoutput>
   <p>The contents of the array are as follows:
   <p>#myList#
