Oracle PL SQL 日期日间操作备忘

select updatedate from trans_studycard t
where
to_date('2010-12-17 23:59:59','yyyy-mm-dd hh24:mi:ss') - updatedate >0
and to_date('2010-12-17 23:59:59','yyyy-mm-dd hh24:mi:ss') - updatedate < 3
order by updatedate


六种日期函数:
1.       add_months(日期,number)    指定日期推迟number个月
2.       last_day(日期)   指定日期当月的最后一天
3.       new_time(日期,时区简写)   调整时区
4.       next_day(日期,number)   number表示周几,星期日是1,指定number的日期(一周内或一周后)
5.       months_between(日期1,日期2)   日期1和日期2之间有几个月
6.       sysdate   系统当期那日期和时间
