How do I re-format datetime in MySQL?

To re-format datetime in MySQL, you can use DATE_FORMAT(). MySQL gives in the format yyyy-mm-dd.

Let us first create a table −

mysql> create table DemoTable1558    -> (    -> EmployeeJoiningDate datetime    -> ); Query OK, 0 rows affected (1.10 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable1558 values(CURDATE()); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable1558 values(NOW()); Query OK, 1 row affected (0.14 sec) mysql> insert into DemoTable1558 values('2018-01-10'); Query OK, 1 row affected (0.20 sec) mysql> insert into DemoTable1558 values('2017-12-31'); Query OK, 1 row affected (0.18 sec)

Display all records from the table using select statement −

mysql> select * from DemoTable1558;

This will produce the following output −

+---------------------+ | EmployeeJoiningDate | +---------------------+ | 2019-10-13 00:00:00 | | 2019-10-13 17:55:33 | | 2018-01-10 00:00:00 | | 2017-12-31 00:00:00 | +---------------------+ 4 rows in set (0.00 sec)

Following is the query to re-format date time in MySQL −

mysql> select date_format(EmployeeJoiningDate,'%d-%m-%Y') as changeFormat from DemoTable1558;

This will produce the following output −

+--------------+ | changeFormat | +--------------+ | 13-10-2019   | | 13-10-2019   | | 10-01-2018   | | 31-12-2017   | +--------------+ 4 rows in set (0.00 sec)
