How to update the date format in MySQL?

Let us first create a table −

mysql> create table DemoTable630 (ArrivalDate varchar(100));
Query OK, 0 rows affected (0.55 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable630 values('2015-21-01');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable630 values('2018-25-12');
Query OK, 1 row affected (0.15 sec)
mysql> insert into DemoTable630 values('2019-15-07');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable630 values('2016-31-03');
Query OK, 1 row affected (0.17 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable630;

This will produce the following output −

+-------------+
| ArrivalDate |
+-------------+
| 2015-21-01  |
| 2018-25-12  |
| 2019-15-07  |
| 2016-31-03  |
+-------------+
4 rows in set (0.00 sec)

Following is the query to convert date format −

mysql> select str_to_date(ArrivalDate,'%Y-%d-%m') from DemoTable630;

This will produce the following output −

+-------------------------------------+
| str_to_date(ArrivalDate,'%Y-%d-%m') |
+-------------------------------------+
| 2015-01-21                          |
| 2018-12-25                          |
| 2019-07-15                          |
| 2016-03-31                          |
+-------------------------------------+
4 rows in set (0.00 sec)
