[Qgis-user] Re : Multy field labels

[Junior]

Hi
in your last code, you use both name_geo and NAME_GEO. Field name is case sensitive.
Another approach can be to use concat function which better manages null values than ||...

For physical map need to label summits and elevation points, some of them have name some no, so I need to label them from different fields.
when I use expression :

"NAME_GEO"   ||  "elev"

It works, but summits with no names, (field "NAME_GEO" is empty), has no label at all, according to ArcGis logic they should have only elevation on labels.

I try following expression  
CASE WHEN "name_geo" is null   THEN "NAME_GEO"   ||   "ELEV"  ELSE "elev"

but it return no labels at all.

Thanks All
