Re: Query: Order for the Earliest Latest date

In addition to the id_Site, you also need to grab the MAX(Time) so you have something to sort by. This requires a little trick known as a "groupwise maximum." See http://dev.mysql.com/doc/mysql/en/example-Maximum-column-group-row.html for an explanation and some examples. Greg F
