I current have attribute bar all empty with null values. I would like to fill that attribute starting from 10001, adding +1 to each of the features and having N before the number
So far I have come up with this.
This is only giving N10001 to all features. How can I tell it that it needs to go alongside the column and increment it from the value the feature above has?
I have another attribute that could be used for comparison, attribute object id already has a number sequence for all those null features.
