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
