cfabort, cfexecute, cfif, cflocation, cfloop, cfswitch, cfthrow, cftry

Example

<!--- This shows the use of cfbreak to exit a loop when a condition is met --->
<!--- select courses; use cfloop to find a condition; then break the loop --->
<!--- check that number is numeric --->
<cfif IsDefined("form.number")>
  <cfif Not IsNumeric(form.number)>
    <cfabort> 
    </cfif> 
  </cfif> 
<cfquery name="GetCourses" datasource="cfsnippets">
  SELECT * 
  FROM Courses 
  ORDER by Course_Number 
</cfquery> 
<p> This example uses CFLOOP to cycle through a query to find a value.
(In our example, a list of values corresponding to courses in the Snippets
datasource). When the conditions of the query are met, CFBREAK stops the loop.
<p> Please enter a Course Number, and hit the "submit" button: 
<form action="index.cfm" method="POST"> 
    <select name="courseNum"> 
  <cfoutput query="GetCourses"> 
    <option value="#Course_Number#">#Course_Number# 
    </cfoutput> 
    </select> 
  <input type="Submit" name="" value="Search on my Number"> 
</form> 
<!---- if the courseNum variable is not defined, don't loop through the query --->
<cfif IsDefined ("form.courseNum") IS "True">
  <!--- loop through query until value found, then use CFBREAK to exit query--->
  <cfloop query="GetCourses"> 
    <cfif GetCourses.Course_Number IS form.courseNum> 
      <cfoutput> 
        <h4>Your Desired Course was found:</h4> 
        <pre>#Course_Number# #Descript#</pre> 
      </cfoutput> 
      <cfbreak> 
    <cfelse> 
        <br> Searching... 
    </cfif> 
  </cfloop> 
</cfif>
