I am new to QGIS and am having, what I expect to be, an easy issue. I am working with a multi-polygon shapefile of taxable property parcels in QGIS 3.16.
All it is I am trying to do is select all features whose "FieldA" is empty (or "Null")
In the expression field I have tried:
"FieldA" = 0; or
"FieldA" = NULL
Neither of these work obviously and I am at a bit of an impasse.
