I have a continent shapefile containing the names of its different countries. Unfortunately, many of these countries have more than one entry (i.e. more than one row in the attribute table).
Therefore, when I am trying to add labels of the country names to the map, some of country names are printed out more than one time.
I read Getting list of distinct values from shapefile field using QGIS?, but was not able to apply it to my specific problem.
What can I do about this?
