Question

I have one table with following data..

saleId amount date
-------------------------
  1     2000  10/10/2012
  2     3000  12/10/2012
  3     2000  11/12/2012
  2     3000  12/10/2012
  1     4000  11/10/2012
  4     6000  10/10/2012

From my table I want result with max of sum amount between dates 10/10/2012 and 12/10/2012 which for the data above will be:

saleId  amount 
---------------
1       6000
2       6000
4       6000

Here 6000 is the max of the sums (by saleId) so I want ids 1, 2 and 4.

Answer 1

You have to use Sub-queries like this:

SELECT saleId , SUM(amount) AS Amount
FROM Table1
GROUP BY saleId
HAVING SUM(amount) = 
( 
  SELECT MAX(AMOUNT) FROM
  (
      SELECT SUM(amount) AS AMOUNT FROM Table1
      WHERE date BETWEEN '10/10/2012' AND '12/10/2012'
      GROUP BY saleId
  ) AS A
)
