MySQL如何使用加减运算符进行日期运算？

MySQL如何使用加减运算符进行日期运算？MySQL可以使用加减运算符，通过将INTERVAL关键字添加到时间单位、日期或日期时间来执行日期运算。下面编程教程网小编给大家简单介绍一下几个示例！

将5天添加到特定日期

mysql> Select '2023-09-12' + INTERVAL 5 day;
+-------------------------------+
| '2023-09-12' + INTERVAL 5 day |
+-------------------------------+
| 2023-09-17                    |
+-------------------------------+
1 row in set (0.00 sec)

从特定日期减去5天

mysql> Select '2023-09-12' - INTERVAL 5 day;
+-------------------------------+
| '2023-09-12' - INTERVAL 5 day |
+-------------------------------+
| 2023-09-07                    |
+-------------------------------+
1 row in set (0.00 sec)

从特定日期添加3个小时

mysql> Select '2023-09-12 17:46:10' - INTERVAL 3 hour;
+-------------------------------+
| '2023-09-12 17:46:10' - INTERVAL 3 hour |
+-------------------------------+
| 2023-09-12 20:46:10                    |
+-------------------------------+
1 row in set (0.00 sec)
