DateDiff is probably not available in QofQ as it's a database specific function

Try putting the dateDiff inside your main SELECT statement to show the number of days difference

 select dateDiff(d,createdDate,getDate())  as NumberDays

then in your QofQ you can just check the number of days column...

 where numberOfDays <= 0

I am trying to run
Select *,( (param 1) ) AS target_date,dateDiff(d,11/22/2012,getDate()) as num from myQuery.

And I get an error message

Right. Like gdmaria said, you can't use DateDiff in a QoQ.  It's not a supported.

If you need to use dateDiff, you'll have to move it into your main databasequery instead.

Move this

   ,dateDiff(d,11/22/2012,getDate()) as num

Into your "MyQuery" 's select statement, don't do it in the query-of-query...

Actually, you don't need the database at all for this... it's a static state and current date.  Just do a cfset..

 <cfset days = dateDiff("d", "11/22/2012",  now())>
