Use and discard the rows of the view as they are computed. + <li> Allow flattening of a subquery that is the right-hand operand of + a LEFT JOIN in an aggregate query. + </ol> +<li> A new typedef named <a href="../c3ref/filename.html">sqlite3_filename</a> is added and used to represent + the name of a database file.
