computed column with aggregate function
- by Kindson
I have seven columns in my table:
hours, weight, status, total_hours, total_weight and percentage
total_weight = weight where status = 'X'
total_hours = hours where status = 'X'
percentage = total_hours/sum(weight)
sum(weight) is an aggregate function
I would like to specify formula to generate the three computed columns.
What do i do?
