为了在 MySQL 表的列中存储像“0000-00-00”这样的日期，我们必须将 SQL 模式设置为“allow_invalid_date”。下面的例子将演示它 -
mysql> SET sql_mode = 'allow_invalid_dates';
Query OK, 0 rows affected, 1 warning (0.03 sec)
mysql> Create table test_date(date_order date);
Query OK, 0 rows affected (0.45 sec)
mysql> Insert into test_date(date_order) values('0000-00-00');
Query OK, 1 row affected (0.04 sec)
mysql> Select * from test_date;
+------------+
| date_order |
+------------+
| 0000-00-00 |
+------------+
1 row in set (0.00 sec)
