Multiple insert statement without counter

I often have a need to write an INSERT statement that adds multiple rows to a database. Obviously you can run any ┬ánumber of inserts separately, but that’s innefficient, so I loop over a list with a counter to know when to end. Recently I learned that the counter is unnecessary and you can create a fake SELECT statement to avoid needing a counter

<cfquery>
INSERT INTO Attendees (Schedule_ID, Attendee_ID, Meeting_ID, User_ID)
<cfloop list="#variables[eventlocation]#" index="i">
  SELECT #Schedule_ID#, #i#, #Meeting_ID#, 1
  UNION ALL
</cfloop>
<!--- returns no rows --->
SELECT 0, 0, 0, 0
WHERE 1 = 0
</cfquery>

For the sake of brevity I’ve avoided omitted the cfqueryparam’s that should always be used in queries.
