I have a database with of accidents in an area. I want to show a lable with the type of accident for every occurence. In the database there are multiple entries for the ID in the first column (because the database is populated according to the involvement in the accident).
I want to show only ONE lable for an accident. For every ID number I want to show one label (per accident). Without rule-based labeling the labels are of course multiple.
I don't know how to write a rule to show me what I want.
Can someone help me?
