    oracle sql日期比较:
    在今天之前:
    select*from up_date whereupdate< to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
    select*from up_date whereupdate<= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')

    在今天只后:
    select*from up_date whereupdate> to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
    select*from up_date whereupdate>= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')

    精确时间:
    select*from up_date whereupdate= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')

    在某段时间内:
    select*from up_date whereupdatebetween to_date('2007-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss') and to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
    select*from up_date whereupdate< to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') andupdate> to_date('2007-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
    select*from up_date whereupdate<= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') andupdate>= to_date('2007-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
