     <function>mysql_num_rows</function> returns the number of rows in
     a result set. This command is only valid for SELECT statements.
     To retrieve the number of rows affected by a INSERT, UPDATE or
     DELETE query, use <function>mysql_affected_rows</function>.

      If you use <function>mysql_unbuffered_query</function>,

      correct value until all the rows in the result set have been 
      retrieved.
