select multiple rows with highest value

Recommended Posts

I have a query it goes like this:

SELECT `person_id` , MAX(exam_score) FROM `results` GROUP BY `exam_score` 

exam_score is column and some values are double

when using query above I get 1 result for each.

So if the exam_score is 10,  8, 9 , 10, 8, 5, 3 10 , 6 it does:

10, 9, 8 , 6, 5, 3

while I would want:

10,10,10, 9, 8, 8

If you want to query multiple databases and group the results into a single result set, you need to use unions or subqueries to get the various results into a single set.
