Convert MySQL date format from yyyy-mm-ddThh:mm:ss.sssZ to yyyy-mm-dd hh:mm:ss ?

Let us first create a table −

mysql> create table DemoTable668(JoiningDate varchar(200));
Query OK, 0 rows affected (0.97 sec)

Insert some records in the table using insert command. We have inserted date in the format yyyy-mm-ddThh:mm:ss.sssZ −

mysql> insert into DemoTable668 values('2001-01-10T06:20:00.000Z');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable668 values('2019-07-20T04:00:00.000Z');
Query OK, 1 row affected (0.12 sec)
mysql> insert into DemoTable668 values('2016-02-12T05:10:50.000Z');
Query OK, 1 row affected (0.17 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable668;

This will produce the following output −

+--------------------------+
| JoiningDate              |
+--------------------------+
| 2001-01-10T06:20:00.000Z |
| 2019-07-20T04:00:00.000Z |
| 2016-02-12T05:10:50.000Z |
+--------------------------+
3 rows in set (0.00 sec)

Following is the query to convert the date format from yyyy-mm-ddThh:mm:ss.sssZ to yyyy-mm-dd hh:mm:ss −

mysql> update DemoTable668
   SET JoiningDate = DATE_FORMAT(STR_TO_DATE(JoiningDate,'%Y-%m-%dT%H:%i:%s.000Z'),'%Y-%m-%d %H:%i:%s');
Query OK, 3 rows affected (0.11 sec)
Rows matched: 3 Changed: 3 Warnings: 0

Let us check table records once again −

mysql> select *from DemoTable668;

This will produce the following output −

+---------------------+
| JoiningDate         |
+---------------------+
| 2001-01-10 06:20:00 |
| 2019-07-20 04:00:00 |
| 2016-02-12 05:10:50 |
+---------------------+
