How can we provide a date with only year (zero months & zero days) value in MySQL?

MySQLMySQLi Database

We can store a date with only year value and have zero months as well as zero-days in MySQL table by disabling NO_ZERO_IN_DATE mode. If this mode is enabled then MySQL will count such kind of date as invalid date and stores all zeros.

mysql> Insert into year_testing (OrderDate) values('2017:00:00');
Query OK, 1 row affected (0.09 sec)

mysql> select * from year_testing;
+------------+
| OrderDate  |
+------------+
| 2017-00-00 |
+------------+
1 row in set (0.00 sec)

mysql> SET sql_mode = 'NO_ZERO_IN_DATE';
Query OK, 0 rows affected (0.00 sec)

mysql> Insert into year_testing(OrderDate) values('2017:00:00');
Query OK, 1 row affected, 1 warning (0.04 sec)

mysql> Select * year_testing;
+------------+
| OrderDate  |
+------------+
| 2017-00-00 |
| 0000-00-00 |
+------------+
1 rows in set (0.00 sec)
