  An example SQL statement is shown
  below:
  
  SELECT C1, COUNT(C2)
  FROM T1
  WHERE C1 = 1
        OR C1 = 2
        OR C1 = 3
  ...
        OR C1 = 99999
  GROUP BY C1
  HAVING COUNT(C2) > 8
         AND C1 > 2
  ;
  
  Db2 incorrectly moved the simple predicate 'C1 > 2' from HAVING
  to WHERE clause thus caused the abend.
  

Problem conclusion

• Db2 has been modified to correctly process the aforementioned
  SQL statement.
