In QGIS Wien, I am performing a spatial query with two layers (points and buffer areas) and receive the following error when creating a new layer with intersecting features: The query from "LayerName" using "FID" in field not possible.

Spatial query settings: - where the feature: intersects - and use the result to: create new selection

In the same file, I have performed the same spatial query with other layers (points and buffer areas) without running into this problem.

How should I go about fixing the error?

  • Have you a unique field in your layers? And what kind of layer are they? shape, postgres ecc..

  • Good questions. Yes, unique field (each column has a unique header). The layer is a shape file of hospital locations in the US (Data: geocommons.com/overlays/106078).

  • I don't know why it happens but it's improbable that it is a bug. What i can suggest is to verify topology of the layer (polygons most of all) or import the 2 layers in grass for a topology correction and then extract them as shape and do again the spatial query.
