'In superset, how do I exclude results where my field contains {} values?
In superset I have a NullType field unappliedcodes that has some values that look like {"BLAH":"Some info"} and others look like {}
My goal is to exclude the {} entries and I have tried WHERE NOT unappliedcodes = '{}' and it does not work.
How do I exclude {} from my results?
