I am getting division by zero on a calculated field ( sum(sales) is 0 )
and I can't find a way around this. I figured out you can't use an
aggregate in a where, and using having the parser must (obviously)
evaluate the select fields before considering teh having clause.
Does anyone have a way around this? Thanks!
select
type,
sum(sales),
sum(cost),
(sum(sales) * sum(cost) / sum(sales)) * 100
from test
group by 1
having sum(sales) != 0
