日期条件未在 MySQL 查询中产生任何结果

Question

我有一个 table 这样的：

> desc my_tab

+-------+--------------+------+-----+---------+-------+
| Field | Type         | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+-------+
| host  | varchar(128) | NO   |     |         |       |
| state | varchar(128) | YES  |     | NULL    |       |
| cdt   | datetime     | YES  |     | NULL    |       |
| mdt   | timestamp    | YES  |     | NULL    |       |
+-------+--------------+------+-----+---------+-------+

有很多行的日期 >= '31-jan-2018 00:00:00'。如果我运行 select * from my_tab 我确实看到了它们。但是，当我运行这个查询时：

select * from my_tab where cdt >= '31-jan-2018 00:00:00'

我没有得到任何结果。

我做错了什么？

Answer 1

https://dev.mysql.com/doc/refman/5.7/en/date-and-time-types.html

Although MySQL tries to interpret values in several formats, date parts must always be given in year-month-day order (for example, '98-09-04'), rather than in the month-day-year or day-month-year orders commonly used elsewhere (for example, '09-04-98', '04-09-98').
