##this cte will give me all the people up in the ladder
select * from EmployeeCTE;


#### DO A SELF JOIN NOW OF THIS CTE because we want names in place of ids

on CTE1.employeeid=CTE2managerid


Select E1.EmployeeName, ISNULL(E2.EmployeeName, 'No Boss') as ManagerName
From EmployeeCTE E1
LEFT Join EmployeeCTE E2
ON E1.ManagerID = E2.EmployeeId
