MySQL獲取當前日期時間前幾天0點   我超怕的- https://www.cnblogs.com/iAmSoScArEd/p/13614058.html

1、獲取當前日期的00點

select timestamp(date_add(curdate(), interval - 0 day));

+--------------------------------------------------+
| timestamp(date_add(curdate(), interval - 0 day)) |
+--------------------------------------------------+
| 2020-09-04 00:00:00                           |
+--------------------------------------------------+

 

2、獲取當前時間的后一天（明天） 00點

select timestamp(date_add(curdate(), interval + 1 day));

+--------------------------------------------------+
| timestamp(date_add(curdate(), interval + 1 day)) |
+--------------------------------------------------+
| 2020-09-05 00:00:00                          |
+--------------------------------------------------+

 

3、獲取當前日期時間的前一天（昨天）00點

select timestamp(date_add(curdate(), interval - 1 day));

+--------------------------------------------------+
| timestamp(date_add(curdate(), interval - 1 day)) |
+--------------------------------------------------+
| 2020-09-03 00:00:00                            |
+--------------------------------------------------+

 

4、獲取本月1號的00點

select timestamp(date_add(curdate(), interval - day(curdate()) + 1 day));
