Question

I have a table called userstbl that has supId (supervisor) and has also userID with relation: one to many -> supid has many userid (same table).

ex. 
- uid:1 
  name: john
  supid:
...... 
- uid:2 
  name: smith
  supid: 1

How do I get all users grouped by supervisor name? thanks

Answer 1

Join the table with itself. In order to do that you will need to alias the table. Something like

select sup.name, usr.name
from userstbl usr
left join userstbl sup
on sup.userId = usr.supId
order by sup.name
