The above sql executes the above result is wrong, 'MGR is null' has only one
line of data, and the 'comm' of this line is also null, the correct result is
to return empty data.
But the following sql execution results are correct.
{code:java}
select e1.*
from "scott".emp e1
inner join "scott".emp e2 on e1.COMM=e2.COMM <-- Here reduce the condition
WHERE e1.MGR is null;
