    progressive number

    Consider two tables:

    book(id, title, date_written , author_id)
    author(id, name)

    the date_written field is a DATE field ad rappresents the date the book
    was written.

    i would like to make a query like this:

    SELECT name , title , date_written
    FROM book INNER JOIN author ON ( book.author_id = author.id )
    ORDER BY author.id , time_written

    the result would be

    King , Running Man , 1978-9-12
    King , Salem's Lot , 1980-3-29
    [...]
    Shakespeare, Romeo and Juliet , 1214-6-13
    Shakespeare , Amlet , 1216-11-6
    Shakespeare , ... , 1226-5-22
    [...]

    but I would like to add a column with the "sequence number" of the book,
    related to the author, like

    King , Running Man , 1 , 1978-9-12
    King , Salem's Lot , 2 , 1980-3-29
    [...]
    Shakespeare, 1 , Romeo and Juliet , 1214-6-13
    Shakespeare , 2 , Amlet , 1216-11-6
    Shakespeare , 3 , ... , 1226-5-22
    [...]

    what query must I issue?
    can anyone help me?
