Using Time datatype in MySQL without seconds?

You need to use DATE_FORMAT() for this. The syntax is as follows −

SELECT DATE_FORMAT(yourColumnName,'%k:%i') as anyAliasName FROM yourTableName;

You can use ‘%H:%i’ for the same result. To understand the above syntax, let us create a table.

The query to create a table is as follows −

mysql> create table TimeDemo
   -> (
   -> Id int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> LastLoginTime time
   -> );
Query OK, 0 rows affected (0.56 sec)

Now you can insert some records in the table using insert command. The query is as follows −

mysql> insert into TimeDemo(LastLoginTime) values('09:30:35');
Query OK, 1 row affected (0.20 sec)
mysql> insert into TimeDemo(LastLoginTime) values('10:45:30');
Query OK, 1 row affected (0.19 sec)
mysql> insert into TimeDemo(LastLoginTime) values('13:33:58');
Query OK, 1 row affected (0.24 sec)
mysql> insert into TimeDemo(LastLoginTime) values('15:45:31');
Query OK, 1 row affected (0.21 sec)
mysql> insert into TimeDemo(LastLoginTime) values('16:40:36');
Query OK, 1 row affected (0.17 sec)

Display all records from the table using a select statement. The query is as follows −

mysql> select *from TimeDemo;

The following is the output −

+----+---------------+
| Id | LastLoginTime |
+----+---------------+
|  1 | 09:30:35      |
|  2 | 10:45:30      |
|  3 | 13:33:58      |
|  4 | 15:45:31      |
|  5 | 16:40:36      |
+----+---------------+
5 rows in set (0.00 sec)

Here is the query to get time without seconds. The query is as follows −

mysql> select DATE_FORMAT(LastLoginTime,'%k:%i') as `Time` from TimeDemo;

The following is the output −

+-------+
| Time  |
+-------+
| 9:30  |
| 10:45 |
| 13:33 |
| 15:45 |
| 16:40 |
+-------+
5 rows in set (0.00 sec)

You can change the format specifier like %H:%i to get the same result without seconds. The query is as follows −

mysql> select DATE_FORMAT(LastLoginTime,' %H:%i') as `Time` from TimeDemo;

The following is the output −

+--------+
| Time   |
+--------+
| 09:30  |
| 10:45  |
| 13:33  |
| 15:45  |
| 16:40  |
+--------+
5 rows in set (0.00 sec)
