I don't know how to filter the attribute table in QGIS. I have two columns,
"DN_2", both with values from Corine Land Cover (111, 112, 223, etc).
I try to select the rows that have the same value. For example.
"DN": 111, and
"DN_2": 111, to erase them, and have only values that are different on the same row
Is there a way to filter this?
