Use BETWEEN to find the date and time between joining and relieving date. NOW() is used to get the current date and time for comparison.
Let us first create a table −
mysql> create table DemoTable771 ( Joiningdate datetime, Relievingdate datetime ); Query OK, 0 rows affected (1.15 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable771 values('2016-01-21','2016-09-23');
Query OK, 1 row affected (0.27 sec)
mysql> insert into DemoTable771 values('2019-01-21','2019-09-23');
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable771 values('2017-04-01','2018-12-31');
Query OK, 1 row affected (0.20 sec)
mysql> insert into DemoTable771 values('2019-04-01','2019-12-31');
Query OK, 1 row affected (0.25 sec)Display all records from the table using select statement −
mysql> select *from DemoTable771;
This will produce the following output -
+---------------------+---------------------+ | Joiningdate | Relievingdate | +---------------------+---------------------+ | 2016-01-21 00:00:00 | 2016-09-23 00:00:00 | | 2019-01-21 00:00:00 | 2019-09-23 00:00:00 | | 2017-04-01 00:00:00 | 2018-12-31 00:00:00 | | 2019-04-01 00:00:00 | 2019-12-31 00:00:00 | +---------------------+---------------------+ 4 rows in set (0.00 sec)
Following is the MySQL query to find the date records wherein the current date and time is in between the JoiningDate and RelievingDate −
mysql> select *from DemoTable771 where NOW() between Joiningdate and Relievingdate;
This will produce the following output -
+---------------------+---------------------+ | Joiningdate | Relievingdate | +---------------------+---------------------+ | 2019-01-21 00:00:00 | 2019-09-23 00:00:00 | | 2019-04-01 00:00:00 | 2019-12-31 00:00:00 | +---------------------+---------------------+ 2 rows in set (0.07 sec)
