MySQL 如何在MySQL表的年份类型列中自动插入当前年份？

你可以使用MySQL查询中的CURDATE()或NOW()来完成这个操作，如下所示−

mysql> Insert into year1(Year_Copyright) values (CURDATE());
Query OK, 1 row affected, 1 warning (0.06 sec)

mysql> Select * from year1;
+----------------+
| Year_Copyright |
+----------------+
|           2017 |
|           2017 |
+----------------+
2 rows in set (0.00 sec)

mysql> Insert into year1(Year_Copyright) values (NOW());
Query OK, 1 row affected, 1 warning (0.06 sec)

mysql> Select * from year1;
+----------------+
| Year_Copyright |
+----------------+
|           2017 |
|           2017 |
|           2017 |
+----------------+
1 rows in set (0.00 sec)
