Hi,
Not sure why the ArcGis logic does not work. Any ways, try the
following for your query. (You inverted your is null... and where asking
QGIS to add 2 field in the label only when it is null and QGIS does not
seem to do that.)
Case When "name_geo" is null then "ELEV" *else* "name_geo" || "ELEV" *end*
not
CASE WHEN "name_geo" is null THEN "NAME_GEO" || "ELEV" * ELSE* "elev"
Cheers!
