Question

Hoe can I do following thing without using a VIEW from one Query.

!--CREATE THE VIEW

CREATE OR REPLACE VIEW BDGTMGR
AS
  SELECT MANAGERID,SUM(BUDGET) AS BDGT FROM 
  N_DEPT GROUP BY MANAGERID ;

!-- THEN GET RESULT FROM THE VIEW

SELECT MANAGERID FROM BDGTMGR WHERE BDGT = (select MAX(BDGT) FROM BDGTMGR);

Here N_DEPT is may original Table which has columns named DID, MANAGERID and BUDGET.

I want to get MANAGERID who controls Maximum Budget. A Manager can control more than one Department. DID is the primary key for this table.

How can I do this?

Answer 1

select   MANAGERID,SUM(BDGT) 
from     N_DEPT 
group by MANAGERID 
order by SUM(BDGT) desc limit 1
