DEVELOPING COLDFUSION 9 APPLICATIONS
The CFML Programming Language
<!--- Do the query --->
<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>
This example uses the query object built-in variable CurrentRow to index the first dimension of the array.
