How to order by timestamp in MySQL?
To order by timestamp, use the ORDER BY as in the following syntax −
select *from yourTableName ORDER BY STR_TO_DATE(`yourColumnName`,'%m/%d/%Y%h:%i:%s %p');
Let us first create a table −
mysql> create table DemoTable -> ( -> `timestamp` varchar(100) -> ); Query OK, 0 rows affected (0.56 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('06/22/2019 01:10:20 PM'); Query OK, 1 row affected (0.13 sec) mysql> insert into DemoTable values('06/22/2019 12:00:27 PM'); Query OK, 1 row affected (0.26 sec) mysql> insert into DemoTable values('06/22/2019 06:56:20 AM'); Query OK, 1 row affected (0.23 sec) mysql> insert into DemoTable values('06/22/2019 07:10:11 AM'); Query OK, 1 row affected (0.15 sec)
Display all records from the table using select statement −
mysql> select *from DemoTable;
Output
This will produce the following output −
+------------------------+ | timestamp | +------------------------+ | 06/22/2019 01:10:20 PM | | 06/22/2019 12:00:27 PM | | 06/22/2019 06:56:20 AM | | 06/22/2019 07:10:11 AM | +------------------------+ 4 rows in set (0.00 sec)
