ArrayResize

Resets an array to a specified minimum number of elements. This can improve performance, if used to size an array to its expected maximum. For more than 500 elements, use ArrayResize immediately after using the ArrayNew tag.

ColdFusion arrays expand dynamically as data is added.

True, on successful completion.

Array functions

ArrayResize(array, minimum_size)

<h3>ArrayResize Example</h3>
<!--- perform a query to get the list --->
<cfquery name = "GetCourses" datasource = "cfsnippets">
SELECT * FROM Courses
</cfquery>
<!--- make a new array --->
<cfset MyArray = ArrayNew(1)>
<!--- resize that array to the number of records
in the query --->
<cfset temp = ArrayResize(MyArray, GetCourses.RecordCount)>
<cfoutput>
The array is now #ArrayLen(MyArray)# elements, to match
the query of #GetCourses.RecordCount# records.
</cfoutput>
