Description

I was running a query from cbo_gby_empty.q:

select unionsrc.key, unionsrc.value FROM (select 'max' as key, max(c_int) as value from cbo_t3 s1
  UNION  ALL
      select 'min' as key,  min(c_int) as value from cbo_t3 s2
    UNION ALL
        select 'avg' as key,  avg(c_int) as value from cbo_t3 s3) unionsrc order by unionsrc.key;

and got the following exception:
