Can we write recursive queries in Teradata.
I have a requirement wherein I need to display Hierarchy tree for a supervisor.
The table would have 2 fields empid and supervisor Id:-
Employee-Id Supervisor-id 1 --- 2 1 3 2 4 2 5 4 6 4
I want it to be implemented in a single query ..
Below is a pseudocode for recursive solution to same:-
DisplayTree(Supervisor_id) ( If emp_id not in ( supervisor's list) display empid exit Else Display empid CALL displayTree(emp_id) End if )
Thanks and Regards,
