Here is my first query that works fine.

SELECT count(event_log_id) as icount, cast(youth_name as varchar(max)) as yname
FROM CIRComplete
WHERE  actual_date between '2012-01-01' and '2012-04-30'
  AND is_deleted = '0' AND Closed = '1' 
GROUP BY cast(youth_name as varchar(max))

This will give me two columns, icount and yname

I want to perform a second query that will give me yname and icount where icount > 1

I have been at this for hours now and have finally decided to ask for help.

Why a second query? This should do:

SELECT
   count(event_log_id) as icount ,
   cast(youth_name as varchar(max)) as yname 
   FROM CIRComplete 
   WHERE (actual_date between '2012-01-01' and '2012-04-30') and 
         is_deleted = '0' and Closed = '1' 
   GROUP BY cast(youth_name as varchar(max))
   HAVING count(event_log_id) > 1

Thank you all for the quick response. I totally forgot about the Having clause. - Esteban Hathaway

Is using an alias in the having clause really permissible? - Mithrandir

Depends on the database, but this is non-standard and uncommon SQL. - gordon linoff
