    Hi Lynn,

    I get the following error when I parse your script:

    Msg 156, Level 15, State 1, Line 6

    Incorrect syntax near the keyword 'over'.

    I'm using SQL Server 2008 R2.

    He missed the () after ROW_NUMBER. Make sure you understand this code before you use it. 🙂

    with DelDups as (

    select

    AccountCode,

    StartDate,

    EndDate,

    rn = row_number() over (partition by AccountCode order by StartDate desc)

    from

    t_account_code

    )

    delete from DelDups

    where rn > 1;
