Hi, I have a table with this columns: machine, date and area.
Now i need a view with machine an week, calculated from date, and sum(area), where date between CURRENT_DATE and now+N days. Okay, this is not the problem, it works fine. (the original table and the view is more complex) The problem is, i need also rows for machine and week with no entrys in the table. For this rows the sum(area) shold be NULL ore 0. In other words: for every machine i need M rows, and M must be constant.
