   @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.
   ```SQL
   CASE
     when ISTRUE(IsDeleted) then 1
     else 0
   END
   ```
   
   2. create a select in FilterBox use the derived column instead of original column.
