[GitHub] [arrow-datafusion] HaoYang670 commented on issue #4335: can't compare boolean type with NULL type

HaoYang670 commented on issue #4335:
URL: https://github.com/apache/arrow-datafusion/issues/4335#issuecomment-1324618829

   Two cases not supported yet:
   ```sql
   ❯ select null and null;
   ArrowError(ExternalError(Internal("Cannot evaluate binary expression And with types Null and Null")))
   ❯ select null or null;
   ArrowError(ExternalError(Internal("Cannot evaluate binary expression Or with types Null and Null")))
   ```
   While on Postgre, we get nulls: https://onecompiler.com/postgresql
