@geido @niyouzhu refer from Dremio Document: https://docs.dremio.com/software/sql-reference/sql-functions/functions/istrue/?parent=boolean

There is a workaround for this case.

1. create a derived column(calculated column in Superset). the new derived column type is an integer.

CASE
  when ISTRUE(IsDeleted) then 1
  else 0
END

1. create a select in FilterBox use the derived column instead of original column.
