Subject: Most data sort
Dear All,
I need your help to how to call the database.
I've got a mysql database as follows:
------------------
Name | qty
-----------------
A 1
B 2
A 4
A 1
B 1
A 2
C 2
D 1
C 4
How calling if I want to sort the data according to the most, or the
result will look like this
A = 7
C = 6
B = 3
D = 1
Thanks a lot
