Here, we will see an example wherein we are inserting dates and updating them while using the INSERT query.
Let us first create a table −
mysql> create table DemoTable816(DueDate datetime); Query OK, 0 rows affected (0.45 sec)
Insert some records in the table using the insert command. Here is the query to add (minutes/hours/days/months/ years) to date when performing INSERT −
mysql> insert into DemoTable816 values(date_add(now(),interval 3 minute));
Query OK, 1 row affected (0.16 sec)
mysql> insert into DemoTable816 values(date_add('2018-01-21 00:00:00',interval 3 Hour));
Query OK, 1 row affected (0.52 sec)
mysql> insert into DemoTable816 values(date_add('2016-11-11 12:40:00',interval 3 Day));
Query OK, 1 row affected (0.17 sec)
mysql> insert into DemoTable816 values(date_add('2018-12-01 11:00:00',interval 3 Month));
Query OK, 1 row affected (0.18 sec)
mysql> insert into DemoTable816 values(date_add('2011-03-21 10:00:00',interval 3 Year));
Query OK, 1 row affected (0.16 sec)Display all records from the table using select statement −
mysql> select *from DemoTable816;
This will produce the following output −
+---------------------+ | DueDate | +---------------------+ | 2019-08-03 13:08:43 | | 2018-01-21 03:00:00 | | 2016-11-14 12:40:00 | | 2019-03-01 11:00:00 | | 2014-03-21 10:00:00 | +---------------------+ 5 rows in set (0.00 sec)
