I want to create a custom column that would be true or false depending on whether a column is null or not, and not having any luck. It reproduces with sample data, too:
- Start a new question using Sample Database, Reviews table
- Try to add a new custom column
- Try to specify
isnull([Product ID] )as expression
I get the error that say "Expecting expression but found function isnull returning boolean", even though my reading of Improve Custom Expression Experience · Issue #14214 · metabase/metabase · GitHub suggests that isNull should work just fine everywhere, and the hint for isNull shows exactly the usage I'm trying to do. I am using version 0.44.
Any idea what I am doing wrong?
