1、日期转换
select to_date('2014-11-27','yyyy-MM-dd') from dual;
select to_date('20141127','yyyyMMdd') from dual;
select to_date('20141127','yyyy-MM-dd') from dual;
select to_date('2004-11-27 00:00:00','yyyy-MM-dd hh24:mi:ss') from dual;
select to_date(TRUNC('20141127'),'yyyy-MM-dd') from dual;2、无效月份
select to_date('2014-11-27','yyyyMMdd') from dual;不能这样转换
