Hi,
This is not a bug.
I think it's a mistake in understanding
aggregate functions and grouping.
A typical example for a count/group operation
would be
Tell me about the number of employees in each department.
in SQL
select count(employee), department from employee_table group by depatment ;
AFAIK if you use an aggregate function on a column and
group by this column the result is undefined.
Re-think what you want to query.
