oracle sql日期比较:
在今天之前:
select * from up_date where update < to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
select * from up_date where update <= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
select * from up_date where update <= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
在今天只后:
select * from up_date where update > to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
select * from up_date where update >= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
select * from up_date where update >= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
精确时间:
select * from up_date where update = to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
在某段时间内:
select * from up_date where update between 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 where update < to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') and update > to_date('2007-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
select * from up_date where update <= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') and update >= to_date('2007-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
select * from up_date where update < to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') and update > to_date('2007-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
select * from up_date where update <= to_date('2007-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') and update >= to_date('2007-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
