Attributes

Usage

This tag is equivalent to a return statement within a cfscript tag. It accepts one return variable argument. To return more than one value, populate a structure with name-value-pairs, and return the structure with this tag.

To access the result value from this tag, you use the variable scope that is the value of the cfinvoke tag returnVariable attribute.

You can code a maximum of one cfreturn tag within a function.

For example code, see Building and Using ColdFusion Components in the Developing ColdFusion Applications.

    <cffunction name="getEmp">

             FROM tblEmployees 
         </cfquery>
