Working with Documents, Charts, and Reports
Another possible use of advanced query mode is to test for passed parameters in the URL or FORM scopes and use
those parameters to retrieve data, as the following example shows:
<!--- First look for URL param. URL overrides cfreportparam. --->
<cfif isDefined("url.deptidin")>
<cfset param.deptidin = url.deptidin>
</cfif>
<!-- Then look for FORM param. Overrides URL param. --->
<cfif isDefined("form.deptidin")>
<cfset param.deptidin = form.deptidin>
</cfif>
<cfquery name="CFReportDataQuery" datasource="cfdocexamples">
SELECTLastName, FirstName, Dept_ID
FROMEmployee
WHERE (Dept_ID = #param.deptidin#)
</cfquery>
