ArraySet (arrayname, startrow, endrow, value)

ArraySet (myarray, 1, 100, "")

<cfloop index="loopcount" from=1 to=12>
<cfset months[loopcount]=MonthAsString(loopcount)>
</cfloop>

<cfloop index="loopcount" from=1 to=12>
<cfoutput>
#months[loopcount]#<br>
</cfoutput>
</cfloop>

<cfloop index="loopcount" from=1 to=12>
<cfloop index="loopcount2" from=1 to=2>
<cfset my2darray[loopcount][loopcount2]=(loopcount * loopcount2)>
</cfloop>
</cfloop>

<p>The values in my2darray are currently:</p>

<cfloop index="OuterCounter" from="1" to="#ArrayLen(my2darray)#">

<cfset arrayName[index]=queryColumn[row]>

In the following example, a cfloop tag places four columns of data from a sample data source into an array, myarray.

<cfquery name="test" datasource="cfdocexamples">
SELECT Emp_ID, LastName, FirstName, Email
FROM Employees
</cfquery>

<!--- Declare the array --->
<cfset myarray=arraynew(2)>

<!--- Populate the array row by row --->
<cfloop query="test">
<cfset myarray[CurrentRow][1]=Emp_ID>
<cfset myarray[CurrentRow][2]=LastName>
<cfset myarray[CurrentRow][3]=FirstName>
<cfset myarray[CurrentRow][4]=Email>
</cfloop>

<!--- Now, create a loop to output the array contents --->
<cfset total_records=test.recordcount>
<cfloop index="Counter" from=1 to="#Total_Records#">
<cfoutput>
ID: #MyArray[Counter][1]#,
LASTNAME: #MyArray[Counter][2]#,
FIRSTNAME: #MyArray[Counter][3]#,
EMAIL: #MyArray[Counter][4]# <br>
</cfoutput>
</cfloop>
