      Description

      LogicalProject(EMPNO=[$0])
        LogicalSortExchange(distribution=[hash[1]], collation=[[0]])
          LogicalProject(EMPNO=[$0], ENAME=[$1], DEPTNO=[$7])
            LogicalTableScan(table=[[scott, EMP]])
      

      In this case the column `DEPTNO` is not required in LogicalSortExchange nor in the Project top on it.
