Hi, Should be a simple one.

Database is mydb. One of the columns is mydata.

What SELECT query do I need in order to select the top 3 occuring results from mydata, but sorted alphabetically?

For example, if my data is this:

mydata
======
kilo (x 1 occurrence)
lima (x 9 occurrences)
golf (x 5 occurrences)
echo (x 9 occurrences)
zulu (x 8 occurrences)

How do I get it to return "echo, lima, zulu", which are the top three frequently occurring entries sorted alphabetically? Thanks!

EDIT: Just to add, they need to be distinct entries. Thanks!
