Dear List,I have a geopackage database and tried to use a spatial sql function (st_area) using the db manager in qgis 3.4 --> select st_area(geom) from polygon_filename. The function is available, but the result is Null. What is the problem?
Thanks a lot Kind regards Klaus _______________________________________________ Qgis-user mailing list Qgis-user@lists.osgeo.org List info: https://lists.osgeo.org/mailman/listinfo/qgis-user Unsubscribe: https://lists.osgeo.org/mailman/listinfo/qgis-user
