<h3>IsQuery Example</h3>

<cfoutput>#GetEmployees#</cfoutput>

<cfif IsSimpleValue(GetEmployees)>

SELECT *
FROM employees
</cfquery> 

<p>After the query is run, GetEmployees contains a number of rows 
that look like this (display limited to three rows):
<cfoutput QUERY = "GetEmployees" MaxRows = "3">
