For this, you can use INTERVAL in MySQL. Let us first create a table −
mysql> create table DemoTable1509 -> ( -> ArrivalTime datetime -> ); Query OK, 0 rows affected (0.51 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1509 values('2018-01-21 10:20:30');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable1509 values('2019-04-01 11:00:00');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable1509 values('2015-12-12 05:45:20');
Query OK, 1 row affected (0.15 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1509;
This will produce the following output −
+---------------------+ | ArrivalTime | +---------------------+ | 2018-01-21 10:20:30 | | 2019-04-01 11:00:00 | | 2015-12-12 05:45:20 | +---------------------+ 3 rows in set (0.00 sec)
Here is the query to MySQL update datetime column and add 10 years 3 months 22 days and 10 hours, 30 minutes to existing data −
mysql> update DemoTable1509 -> set ArrivalTime=ArrivalTime+interval 10 year + interval 3 month +interval 22 day+interval 10 hour+interval 30 minute; Query OK, 3 rows affected (0.17 sec) Rows matched: 3 Changed: 3 Warnings: 0
Let us check the table records once again −
mysql> select * from DemoTable1509;
This will produce the following output −
+---------------------+ | ArrivalTime | +---------------------+ | 2028-05-13 20:50:30 | | 2029-07-23 21:30:00 | | 2026-04-03 16:15:20 | +---------------------+ 3 rows in set (0.00 sec)
