Changing year in MySQL date?
To change the year in MySQL date, you need to use DATE_FORMAT() function with UPDATE command. The syntax is as follows.
UPDATE yourTableName SET yourDateColumnName = DATE_FORMAT(yourDateColumnName ,'yourYearValue-%m-%d');
To understand the above syntax, let us create a table. The query to create a table is as follows −
mysql> create table ChangeYear -> ( -> id int not null auto_increment, -> ArrivalTime date, -> PRIMARY KEY(id) -> ); Query OK, 0 rows affected (0.83 sec)
Insert some records in the table using insert command −
mysql> insert into ChangeYear(ArrivalTime) values(date_add(now(),interval -2 year));
Query OK, 1 row affected, 1 warning (0.20 sec)
mysql> insert into ChangeYear(ArrivalTime) values('2012-10-24');
Query OK, 1 row affected (0.18 sec)
mysql> insert into ChangeYear(ArrivalTime) values('2016-3-21');
Query OK, 1 row affected (0.19 sec)
mysql> insert into ChangeYear(ArrivalTime) values('2015-4-24');
Query OK, 1 row affected (0.20 sec)
mysql> insert into ChangeYear(ArrivalTime) values(curdate());
Query OK, 1 row affected (0.20 sec)Display all records from the table using select statement. The query is as follows.
mysql> select *from ChangeYear;
The following is the output.
+----+-------------+ | id | ArrivalTime | +----+-------------+ | 1 | 2017-01-07 | | 2 | 2012-10-24 | | 3 | 2016-03-21 | | 4 | 2015-04-24 | | 5 | 2019-01-07 | +----+-------------+ 5 rows in set (0.00 sec)
Here is the query to update only the year in the date column. For our example, let us change the year to 2019 −
mysql> update ChangeYear -> set ArrivalTime = DATE_FORMAT(ArrivalTime,'2019-%m-%d'); Query OK, 4 rows affected (0.12 sec) Rows matched − 5 Changed − 4 Warnings − 0
Check all the updated records from the table using select statement. The query is as follows −
mysql> select *from ChangeYear;
The following is the output displaying the updated year 2019, but rest of the date remains the same −
+----+-------------+ | id | ArrivalTime | +----+-------------+ | 1 | 2019-01-07 | | 2 | 2019-10-24 | | 3 | 2019-03-21 | | 4 | 2019-04-24 | | 5 | 2019-01-07 | +----+-------------+ 5 rows in set (0.00 sec)
