select or sort or what?

you have to use IS NOT NULL in where clause for the date column and MAX aggregate on a autoincrement coulmn. Use this as a sub query for the where clause in a main query.

Try:

C#

SqlConnection con = new SqlConnection(connectionString);
con.Open();
SqlCommand com = new SqlCommand("SELECT * FROM myTable ORDER BY date DESC", con);
SqlDataReader r = com.ExecuteReader();
if (r.Read())
    {
    Console.WriteLine((DateTime) r["date"]);
    }
r.Dispose();
com.Dispose();
con.Dispose();

The "ORDER BY" and "DESC" parts tell it to return the rows in a specific order (in this case by the "date" column) with the newest first.
