    hi i would like to understand how to count in sql with different parameters?

    for example i have

    Date, firstname, name, nationality , mode, origine, id

    1/1/2010 teste teste1 fr in p 01

    15/07/2005 toto tata lb out L 02

    01/03/2012 teste teste1 fr in P 01

    i would like to know how many poeple have the most entry in my database

    for example here teste teste1 with Id 01 have the most entry it's 2 record

    so i need to know the top 100 of poeple who have the most entry

    result i need is for example

    id 01 = 2 entry

    id 02= 1 entry

    thanks to help

    select top 100 ID, count(*)

    from YourTable

    group by ID

    Order by count(*)

    I think that should be close to what you are looking for.
