Update MySQL date and increment by one Year?

You can use in-built function date_add() from MySQL. The syntax is as follows −

UPDATE yourTableName SET
yourDateColumnName=DATE_ADD(yourDateColumnName,interval 1 year);

To understand the above syntax, let us first create a table. The query to create a table is as follows −

mysql> create table UpdateDate
   -> (
   -> Id int,
   -> DueDate datetime
   -> );
Query OK, 0 rows affected (0.76 sec)

Insert some records in the table using insert command. The query to insert record is as follows −

mysql> insert into UpdateDate values(1001,'2012-5-21');
Query OK, 1 row affected (0.17 sec)

mysql> insert into UpdateDate values(1002,'2013-8-2');
Query OK, 1 row affected (0.17 sec)

mysql> insert into UpdateDate values(1003,'2014-2-27');
Query OK, 1 row affected (0.10 sec)

mysql> insert into UpdateDate values(1004,'2016-11-1');
Query OK, 1 row affected (0.18 sec)

mysql> insert into UpdateDate values(1005,'2017-12-24');
Query OK, 1 row affected (0.12 sec)

Let us now display all records from the table using select command. The query is as follows −

mysql> select *from UpdateDate;

Output

+------+---------------------+
| Id   | DueDate             |
+------+---------------------+
| 1001 | 2012-05-21 00:00:00 |
| 1002 | 2013-08-02 00:00:00 |
| 1003 | 2014-02-27 00:00:00 |
| 1004 | 2016-11-01 00:00:00 |
| 1005 | 2017-12-24 00:00:00 |
+------+---------------------+
5 rows in set (0.00 sec)

Here is the query that can be used to update date with 1 year using date_add() and interval. The query is as follows −

mysql> update UpdateDate set DueDate=date_add(DueDate,interval 1 year);
Query OK, 5 rows affected (0.15 sec)
Rows matched: 5 Changed: 5 Warnings: 0

Check the table using select command. The query is as follows −

mysql> select *from UpdateDate;

Output

+------+---------------------+
| Id   | DueDate             |
+------+---------------------+
| 1001 | 2013-05-21 00:00:00 |
| 1002 | 2014-08-02 00:00:00 |
| 1003 | 2015-02-27 00:00:00 |
| 1004 | 2017-11-01 00:00:00 |
| 1005 | 2018-12-24 00:00:00 |
+------+---------------------+
5 rows in set (0.00 sec)

Look at the above sample output, all values have been updated. If you want to update a particular date time then use the where condition.
