URL: https://github.com/apache/arrow-datafusion/issues/5646#issuecomment-1497007973

   it's related with `type coercion`, I have a job related with it.
   #5831.
   This PR contains a fix for type coercion of subquery, it will move `cast` from `expression` into `subplan`. It means that we don't `cast expression` in `eval expression` and we do cast before `eval expression`.
