[Qgis-user] Multy field labels

[Nicolas Cadieux]

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!
Nicolas
