Question

I am using mysql 5.0.51b.
I have one table named xyz.
xyz table has a columns abc,location,pqr and lmn
Everytime an information is sent to particular location, its entry is done in xyz table.
I want to have the name of the location to which maximum information is sent.

The way i tried:
First of all i count the number of entries sent to each location using count and group by.
Now, the problem is to have the name(s) of the location with maximum values.

I have used temporary solution:
I use order by clause and limit to get the first record that has max values.
But this has one problem
If two locations has same count then above solution will give only one location and the other with same count will not be returned.

I want to solve this problem
Any hint will be very helpful
Thanks in anticipation

Answer 1

Thank you very much to everyone who has responded to my question and spared time to solve my problem.

However, i have got the solution:

SELECT count( * ) AS cnt2, location
FROM sms
GROUP BY location
HAVING cnt2 = (
SELECT count( * ) AS cnt
FROM sms
GROUP BY location
ORDER BY cnt DESC
LIMIT 1 );

very important hint on http://lists.mysql.com/mysql/203074

The inner query gives you the max count and outer query compares each count with max count.
