Resolved: about using manager_id as 10022
when I M USING 10022 as manager_ID in query A .why mysql showing manager_id as null?
Hi Ayush Sahu,
Without seeing the code\screen shot for your issue with the query, the only 'hint' I got from your comment is that the 'manager_ID' number that is to be used is 110022, not '10022' which is an 'employee_ID'. Copy of screen shot from video to help you verify - if this does not fix the issue, reply with a screen shot and I will review again.
Hope this helps.
