The positional notation is misborn ANSI SQL invention. Why is that

select table_name, column_name AS COLNAME from user_tab_columns
where table_name = 'SERVERS'
ORDER BY 2 is different from

select table_name, column_name AS COLNAME from user_tab_columns
where table_name = 'SERVERS'
ORDER BY 1+1 Received on Fri Jan 07 2005 - 17:41:51 CET
