I have an attribute table where one of the columns (laeskaerm) has been edited/created by checkboxes on 2 different machines.
Result: it contains both 1, 0, true, false and NULL
I'd like to replace 1 with true, and 0 with false. I've tried:
But I can't seem to make it work (QGIS 2.2.0).
Do anyone have any idea whats wrong?
