How to update a MySQL date type column?
Let us first create a table −
mysql> create table DemoTable1451 -> ( -> JoiningDate date -> ); Query OK, 0 rows affected (0.52 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable1451 values('2019-07-21');
Query OK, 1 row affected (0.07 sec)
mysql> insert into DemoTable1451 values('2018-01-31');
Query OK, 1 row affected (0.09 sec)
mysql> insert into DemoTable1451 values('2017-06-01');
Query OK, 1 row affected (0.20 sec)Display all records from the table using select statement −
mysql> select * from DemoTable1451;
This will produce the following output −
+-------------+ | JoiningDate | +-------------+ | 2019-07-21 | | 2018-01-31 | | 2017-06-01 | +-------------+ 3 rows in set (0.00 sec)
Here is the query to update a date type column. We are incrementing the date records with an year −
mysql> update DemoTable1451 set JoiningDate=date_add(JoiningDate, interval 1 year); Query OK, 3 rows affected (0.15 sec) Rows matched: 3 Changed: 3 Warnings: 0
Let us check the table records once again −
mysql> select * from DemoTable1451;
This will produce the following output −
+-------------+ | JoiningDate | +-------------+ | 2020-07-21 | | 2019-01-31 | | 2018-06-01 | +-------------+ 3 rows in set (0.00 sec)
