Re: Ordering of records in group by not possible

Hello all,

I wanted to verify what we are seeing.

Select a, aggregate(b)
from c
group by a
order by a,b

That's a rather odd query... Values in b aren't available to order by, as they have been aggregated. There is no relation to the values in b and the values in your result set.

You could order by "column 2" if you want to order on the results on your aggregate:
	Select a, aggregate(b)
	from c
	group by a
	order by a,2
