Hi Arnaud,

Can you try to update the statistics for this layer? (Go to the "Add Spatialite Layer" dialog, connect to your DB and click "Update Statistics")

#2 Updated by Arnaud Morvan over 7 years ago

I got an error : Error while updating internal statistics

#3 Updated by Arnaud Morvan over 7 years ago

In iterator loop, I call layer.dataProvider().changeAttributeValues({ feature.id() : attrs })
when I comment this line the iterator work correctly
