  • What exactly are you trying to do? Update data on joined tables? – MaryBeth Apr 12 '16 at 20:34
  • Hi, how are you. What I try to do is then updated columns in a data layer with another layer. For example , I have two layers A = Poligono , B = Points . The layer B contains enterros values. Entonce would do two things. 1. Count how many points of the layers B are within the layer A. 2. From the points of the layer B that are within the polygon layer A, I need the sum of their values ​​and paste this sum in a column of created layer A. I hope I have been able to explain . greetings and thanks for your support. – Israel.am Apr 13 '16 at 17:24

The refFunctions plugin does what you want by allowing you to update the values of a field in one layer with those from another layer. Once installed, you'll see a new option in the field calculator called Reference. In your case you want to use the geomwithin function.

  • If you make this a virtual attribute, it will automatically update. – csk Apr 3 '18 at 18:56
