Let’s say I have a contact manager system. There are notes associated to each contact made by employees.

So, here’s my quick example:

ContactName, NoteCount
John, 100
Rob, 10 
Amy, 10
Chris, 10

How do i figure out the that 75% of contacts have 10 notes assoicated with them and that 25% of contacts have 100 notes associated with them?

Please explain what I’m trying to do in Layman’s terms.

    If you really want the percentage of people that have the exact number, use this:

    SELECT
    NoteCount,
    COUNT(*) ContactsWithThisNoteCount,
    COUNT(*) / (SELECT COUNT(*) FROM Contacts) PercentageContactsWithThisNoteCount
FROM 
    Contacts
GROUP BY
    NoteCount

    If you want grouings like “0-9”, “10-99”, and “100+” then you just need a little bit of a calculation in the group by and MIN/MAXon NoteCount.
