mysql

可以直接用大于號，也可以用? between? and

SELECT * FROM users WHERE UPDATE_DATE >= '2021-08-12 11:22:09' AND UPDATE_DATE <= '2021-08-15 11:22:33';SELECT * FROM users WHERE UPDATE_DATE BETWEEN '2021-08-12 11:22:09' AND '2021-08-15 11:22:33';

Oracle

oracle sql日期比較:

在今天之前:

select * from up_date where update < to_date('2021-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') select * from up_date where update <= to_date('2021-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')

在今天只后:

select * from up_date where update > to_date('2022-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') select * from up_date where update >= to_date('2022-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss')

精確時間：

select * from up_date where update = to_date('2022-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') 在某段時間內(nèi): select * from up_date where update between to_date('2022-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss') and to_date('2022-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') select * from up_date where update < to_date('2022-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') and update > to_date('2022-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss') select * from up_date where update <= to_date('2022-09-07 00:00:00','yyyy-mm-dd hh24:mi:ss') and update >= to_date('2022-07-07 00:00:00','yyyy-mm-dd hh24:mi:ss')
