Question

I am trying to write a query that lists the name of a manager and the number of people they manage.

In the Manager table we have the managers name and id.

In the Employee table we have the employees name, id and managerID.

I don’t understand how to get the count of the employees that a manager manages.

Answer 1

SELECT COUNT(e.EmpID), m.ManagerID
FROM Employee e
INNER JOIN Manager m 
ON e.ManagerID= m.ManagerID
GROUP BY m.ManagerID
