    analytical stats query

    Hi,

    I have to create a report that shows number of people attending web casts.

    I need to show the following:

    # of people saw 1 web cast:
    # of people that saw more than one web cast:
    # of peoople that saw more than 2 web cast:
    .
    .
    .
    # of people that saw more than n web casts:
    ---------------------------------------------------------

    I have a table called web_casts with the following attributes:

    web_cast_name,
    fname,
    lname,
    email
    -------------------------------------------------------------


    Thanks for all the help

    Start by ...
    Code:
    select fname||lname||email unq_person,
     count(distinct web_cast_name) wc_views
    group by fname||lname||email
    .. to count the web casts per person.

    Then ...
    Code:
    select wc_views,count(*) persons
    from
    (
    select fname||lname||email unq_person,
     count(distinct web_cast_name) wc_views
    group by fname||lname||email
    )
    group by wc_views
    .. to count the number of people per number of views
    There's a start for you, anyway.
