After enabling the SQL MODE to ALLOW_INVALID_DATES, MySQL will also be able to store invalid dates in the table. The example is given below to understand it −
mysql> Insert into order1234(ProductName, Quantity, Orderdate) values('B',500,'2015-11-31');
Query OK, 1 row affected (0.06 sec)
mysql> Select * from order1234;
+-------------+----------+--------------+
| ProductName | Quantity | OrderDate |
+-------------+----------+--------------+
| A | 500 | 0000-00-00 |
| B | 500 | 2015-11-31 |
+-------------+----------+--------------+
2 rows in set (0.00 sec)We can see MySQL also inserts the invalid date in a table.
