How to split the datetime column into date and time and compare individually in MySQL?

MySQLMySQLi Database

Let us first create a table −

mysql> create table DemoTable805(LoginDate datetime);
Query OK, 0 rows affected (0.63 sec)

Insert some records in the table using insert command −

mysql> insert into DemoTable805 values('2019-01-31 12:45:20');
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable805 values('2017-11-01 10:20:30');
Query OK, 1 row affected (0.14 sec)
mysql> insert into DemoTable805 values('2016-03-12 04:10:00');
Query OK, 1 row affected (0.35 sec)
mysql> insert into DemoTable805 values('2018-12-24 05:01:00');
Query OK, 1 row affected (0.13 sec)

Display all records from the table using select statement −

mysql> select *from DemoTable805;

This will produce the following output −

+---------------------+
| LoginDate           |
+---------------------+
| 2019-01-31 12:45:20 |
| 2017-11-01 10:20:30 |
| 2016-03-12 04:10:00 |
| 2018-12-24 05:01:00 |
+---------------------+
4 rows in set (0.00 sec)

Here is the query to split the DateTime column into date and time and compare individually −

mysql> select cast(LoginDate AS date),cast(LoginDate AS Time) from DemoTable805;

This will produce the following output −

+-------------------------+-------------------------+
| cast(LoginDate AS date) | cast(LoginDate AS Time) |
+-------------------------+-------------------------+
| 2019-01-31              | 12:45:20                |
| 2017-11-01              | 10:20:30                |
| 2016-03-12              | 04:10:00                |
| 2018-12-24              | 05:01:00                |
+-------------------------+-------------------------+
4 rows in set (0.03 sec)
