remove oldest records from duplicates

  • Brain freeze! Using the following example:

    Lastname FirstName DateModified

    Smith Jim 1/14/07

    Smith Jim 2/28/08

    Richardson Alex 5/15/07

    Richardson Alex 7/05/07

    etc...

    How can I return only the latest date modified *for each Lastname Firstname combination* (aka exclude the older dates modified)?

    (I'll be using the resulting dates modified from the subset to match against an original table)

    I think this is what you are looking for:

    select

    Lastname,

    Firstname,

    max(DateModified) as DateModified

    from

    dbo.MyTable

    group by

    Lastname,

    Firstname
