Inconsistency between oracle and mysql statement results

The same SQL results in oracle and mysql are inconsistent, oracle includes 0-super administrator, mysql does not.What is the reason for this?
Accepted answer 1:
left join will not filter left table data.That must be the where condition filter.Do you see that the values in the parents_ column of the super administrator row in the two libraries are the same?
Other Answer 1:

Other Answer 2:
Is the data exactly the same?
Other Answer 3:
Both tables have the data of super-control data, but it is very strange that one can be checked out and the other cannot be checked out
Other Answer 4:
Why do I think the data in the tables in your two libraries is inconsistent?
Other Answer 5:
Are all transactions committed?
Other Answer 6:
No, there is no transaction for the query.
Other Answer 7:
Agree with the statement of aisql upstairs and see if the data is filtered out because of the where condition
