选择日期时间范围之间的数据

Question

我有一个名为lap的表，它包含如下数据：

code | name | details | time_stamp
===================================
1a   | A-wan| Goods   | 01-02-2019 11:08:10
3a   | D-wan| Goods   | 05-02-2019 01:00:40
2a   | B-gud| Foods   | 02-03-2019 05:31:05
1a   | A-cro| Bills   | 02-03-2019 15:30:15
1a   | A-set| Bills   | 03-03-2019 17:24:35
1a   | C-won| Goods   | 03-03-2019 10:21:55
1a   | C-gud| Foods   | 04-03-2019 01:30:06

我使用了dd-mm-yy hh:mm:ss格式

和我的查询SELECT * FROM lap WHERE time_stamp >= '02-03-2019 00:00:00' AND time_stamp <= '03-03-2019 23:59:59'

结果是

code | name | details | time_stamp
===================================
3a   | D-wan| Goods   | 05-02-2019 01:00:40
2a   | B-gud| Foods   | 02-03-2019 05:31:05
1a   | A-cro| Bills   | 02-03-2019 15:30:15
1a   | A-set| Bills   | 03-03-2019 17:24:35
1a   | C-won| Goods   | 03-03-2019 10:21:55

它包括3a | D-wan| Goods | 05-02-2019 01:00:40的数据3a | D-wan| Goods | 05-02-2019 01:00:40 3a | D-wan| Goods | 05-02-2019 01:00:40我认为这可能是因为05比02大，尽管它是不同的月份。 任何人都可以帮助这个？

当我在同一日期更改查询时，它运行良好SELECT * FROM lap WHERE time_stamp >= '02-03-2019 00:00:00' AND time_stamp < '02-03-2019 23:59:59'

code | name | details | time_stamp
===================================
2a   | B-gud| Foods   | 02-03-2019 05:31:05
1a   | A-cro| Bills   | 02-03-2019 15:30:15

Answer 1

你应该使用date函数然后它会起作用，

SELECT * FROM lap WHERE time_stamp BETWEEN '02-03-2019' AND '03-03-2019';

或者您可以将格式更改为yyyy-mm-dd到您的后端并检查

SELECT * FROM lap WHERE time_stamp BETWEEN '2019-03-02' AND '2019-03-03';

Answer 2

尝试

 SELECT * FROM lap WHERE time_stamp BETWEEN DATE_FORMAT('02-03-2019 00:00:00', '%d-%m-%Y %h:%m:%s') AND DATE_FORMAT('03-03-2019 23:59:59', '%d-%m-%Y %h:%m:%s');

对于 mysql 日期时间格式，请参阅下面的链接https://dev.mysql.com/doc/refman/8.0/en/datetime.html

如果您以另一种格式传递日期，则最好更改格式。
