Bug report #13268
Selecting features of field name with a leading digit

For a python script I use [feature.id() for feature in layer.getFeatures(QgsFeatureRequest().setFilterExpression("8_1 IS NOT NULL"))] to get all feature id's that are not null. But it won't find any. While using the expression "8 IS NOT NULL" it will find the first feature starting with an 8. This problem does not occur when changing the layer name to for example A8_1, in that case the expression: "8_1 IS NOT NULL" works.
So I think this has to do something with using leading digits in field names.

"8_1" IS NOT NULL
You are right,
'"8_1" IS NOT NULL' works
