I have an employee table as below
I need to select employee_id, manager_id, result. result should have true or false depends on below conditions.
- If the employee is manager for someone then true
- If the employee has a manager then true
I came up with a query, but I need to know if there are any other better way to do it. This is my query
with manager as ( select distinct manager_id from employee where manager_id is not null ) select e.employee_id, e.manager_id , m.manager_id, case when e.manager_id is not null then true when m.manager_id is not null then true else false end as Result from employee e left join manager m on e.employee_id = m.manager_id
and the result should come like this
