I have a map of soil properties. I am trying to exclude areas that are designated for protection from a selection on this map.

I have tried to use the following query:

SOIL_TEXTURE = 'clay' AND SPA_NAME IS NULL but this does not work

Field names need to be double-quoted in your expression. See, for example, the QGIS documentation on expressions.
