DB2 does not like it.

This runs and returns data:
> SELECT INFO5FILES.APAMT.DEBAMT FROM INFO5FILES.APAMT                 SELECT statement run complete.
                   
This fails to prepare:
> SELECT INFO5FILES.APAMT.DEBAMT FROM INFO5FILES.APAMT having 1 > 2    Column DEBAMT or function specified in SELECT
listnot valid.
