Example
    <!--- This example shows the use of CFUPDATE to change
    records in a datasource. --->
    <!--- if course_ID has been passed to this form, then
    perform the update on that record in the datasource --->

    <cfif IsDefined("form.Course_ID")>
       <!--- check that course_id is numeric --->
          <cfif Not IsNumeric(form.Course_ID)>
             <cfabort>
          </cfif>
       <!--- Now, do the update --->
       <cfupdate datasource="cfsnippets"
          tablename="Courses"
          formfields="Course_ID,Number,Descript">
    </cfif>

    <!--- Perform a query to reflect any updated information if Course_ID is passed
    through a url, we are selecting a record to update ... select only that
    record with the WHERE clause. --->
    <cfquery name="GetCourseInfo" DATASOURCE="cfsnippets">
       SELECT Course_Number, Course_ID, Descript
       FROM Courses
          <cfif IsDefined("url.Course_ID")>
             WHERE Course_ID = #Trim(url.Course_ID)#
          </cfif>
       ORDER by Course_Number
    </cfquery>
