      Description

      In the following query below, SqlValidator return rowtype with the second column as NOT NULL. Since this is a left outer join, it should be nullable.

      select * from
        (select row_number() over (order by sal) from emp) as emp1(r1) 
        left outer join 
        (select  dense_rank() over(order by sal) from emp) as emp2(r2) 
        on (emp1.r1 = emp2.r2)
