Let’s say you need to change the date and add years. For this, use UPDATE command along with DATE_ADD(). Let us first create a table −
mysql> create table DemoTable1984 ( ShippingDate date ); Query OK, 0 rows affected (0.00 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1984 values('2014-01-11'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1984 values('2015-12-23'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1984 values('2017-10-31'); Query OK, 1 row affected (0.00 sec) mysql> insert into DemoTable1984 values('2018-06-01'); Query OK, 1 row affected (0.00 sec)
Display all records from the table using select statement −
mysql> select * from DemoTable1984;
This will produce the following output −
+--------------+ | ShippingDate | +--------------+ | 2014-01-11 | | 2015-12-23 | | 2017-10-31 | | 2018-06-01 | +--------------+ 4 rows in set (0.00 sec)
Here is the query to change the date −
mysql> update DemoTable1984 set ShippingDate=date_add(ShippingDate,interval 2 year); Query OK, 4 rows affected (0.00 sec) Rows matched: 4 Changed: 4 Warnings: 0
Let us check table records once again −
mysql> select * from DemoTable1984;
This will produce the following output −
+--------------+ | ShippingDate | +--------------+ | 2016-01-11 | | 2017-12-23 | | 2019-10-31 | | 2020-06-01 | +--------------+ 4 rows in set (0.00 sec)
