Sql Query for

1

In this MySQL challenge, your query should return the information for the employee with the third highest salary. Write a query that will find this employee and return that row, but then replace the DivisionID column with the corresponding DivisionName from the table cb_companydivisions. You should also replace the ManagerID column with the ManagerName if the ID exists in the table and is not NULL.

Hi,

Thanks for the answer ... I have the 3rd Highest Salary but how to solve

eplace the DivisionID column with the corresponding DivisionName from the table cb_companydivisions. You should also replace the ManagerID column with the ManagerName if the ID exists in the table and is not NULL.

FROM maintable_1YA0N E WHERE

3 =(SELECT COUNT(DISTINCT salary)

FROM maintable_1YA0N WHERE E.salary <= salary)

Hello Mo,
You are a life saver but would like to give some explanation of this please,

SELECT a.ID,a.Name,DivisionName,a.Name as ManagerName,a.Salary
FROM maintable_4EMTN as a
INNER JOIN cb_companydivisions as b
ON a.DivisionID=b.ID
ORDER BY Salary DESC
LIMIT 1
OFFSET 2

If i type this i get the correct result but with a wrong manager name (which is the same as the name of the employee instead of his manager)?Can you tell me what is your 2nd inner join doing exactly cuz i am a bit confused
Thanks in advance!

E.salary FROM maintable_SEAHL E

inner join

cb_companydivisions as i on i.ID = E.DivisionID

inner join

maintable_SEAHL as m on m.ID = E.ManagerID

where
3=(SELECT COUNT(DISTINCT SALARY)
FROM maintable_SEAHL Where E.salary <= salary)
