CFParam, unless you want to go the multiline route:
<cfif structKeyExists(form, "myVar")>
<cfqueryparam type="cf_sql_integer" value="#form.myVar#" />
<cfelse>
<cfqueryparam type="cf_sql_integer" value="" isNull="Yes" />
</cfif>
But you can't go <cfqueryparam type="cf_sql_integer" value="#form.myVar#"
isNull="#NOT
isNumeric(form.myVar)#" />
because value="#form.myVar#" will fail to compile if form.myVar doesn't
exist.

Yes. This is the part that, in my initial reading, I didn't even see.
This doesn't have anything to do with CFQUERYPARAM per se, it's just
that you can't reference a variable that doesn't exist at all.
