Best way to change the date format in MySQL SELECT?

MySQLMySQLi Database

The best way to change the date format in MySQL SELECT is as follows

SELECT DATE_FORMAT(yourColumnName, "%d/%m/%Y %H:%i") AS anyAliasName FROM yourTableName WHERE yourCondition;

To understand the above concept, let us create a table. The query to create a table is as follows

mysql> create table bestDateFormatDemo
   - > (
   - > Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   - > ArrivalDateTime datetime
   - > );
Query OK, 0 rows affected (0.64 sec)

Insert some records in the table using insert command.

The query is as follows

mysql> insert into bestDateFormatDemo(ArrivalDateTime) values(now());
Query OK, 1 row affected (0.11 sec)
mysql> insert into bestDateFormatDemo(ArrivalDateTime) values(date_add(now(),interval -2
year));
Query OK, 1 row affected (0.33 sec)
mysql> insert into bestDateFormatDemo(ArrivalDateTime) values('2014-01-31 13:45:56');
Query OK, 1 row affected (0.15 sec)
mysql> insert into bestDateFormatDemo(ArrivalDateTime) values('2016-02-11 12:40:30');
Query OK, 1 row affected (0.17 sec)
mysql> insert into bestDateFormatDemo(ArrivalDateTime) values('2018-12-31 12:59:59');
Query OK, 1 row affected (0.19 sec)

Display all records from the table using select statement.

The query is as follows

mysql> select *from bestDateFormatDemo;

The following is the output

+----+---------------------+
| Id | ArrivalDateTime     |
+----+---------------------+
|  1 | 2019-02-22 22:50:10 |
|  2 | 2017-02-22 22:50:28 |
|  3 | 2014-01-31 13:45:56 |
|  4 | 2016-02-11 12:40:30 |
|  5 | 2018-12-31 12:59:59 |
+----+---------------------+
5 rows in set (0.00 sec)

Here is the query to change the date format in MySQL select statement

mysql> SELECT DATE_FORMAT(ArrivalDateTime, "%d/%m/%Y %H:%i")AS
changeDateFormat FROM bestDateFormatDemo WHERE Id IN(1,2,3,4,5);

The following is the output

+------------------+
| changeDateFormat |
+------------------+
| 22/02/2019 22:50 |
| 22/02/2017 22:50 |
| 31/01/2014 13:45 |
| 11/02/2016 12:40 |
| 31/12/2018 12:59 |
+------------------+
5 rows in set (0.28 sec)

If you want the hour in 12-hour format, use ‘h’ instead of ‘H’.

The query is as follows

mysql> SELECT DATE_FORMAT(ArrivalDateTime, "%d/%m/%Y %h:%i")AS
changeDateFormat FROM bestDateFormatDemo WHERE Id IN(1,2,3,4,5);

The following is the output

+------------------+
| changeDateFormat |
+------------------+
| 22/02/2019 10:50 |
| 22/02/2017 10:50 |
| 31/01/2014 01:45 |
| 11/02/2016 12:40 |
| 31/12/2018 12:59 |
+------------------+
5 rows in set (0.00 sec)
