Add a single day to datetime field with MySQL INTERVAL
Let us first create a table −
mysql> create table DemoTable -> ( -> DueDate date ->); Query OK, 0 rows affected (2.11 sec)
Insert some records in the table using insert command −
mysql> insert into DemoTable values('2019-01-21');
Query OK, 1 row affected (0.13 sec)
mysql> insert into DemoTable values('2018-12-31');
Query OK, 1 row affected (0.47 sec)
mysql> insert into DemoTable values('2018-12-30');
Query OK, 1 row affected (0.28 sec)
mysql> insert into DemoTable values('2017-02-26');
Query OK, 1 row affected (0.47 sec)Display all records from the table using select statement −
mysql> select *from DemoTable;
This will produce the following output −
+------------+ | DueDate | +------------+ | 2019-01-21 | | 2018-12-31 | | 2018-12-30 | | 2017-02-26 | +------------+ 4 rows in set (0.00 sec)
Here is the query to add a day to DateTime field in MySQL table −
mysql> update DemoTable -> set DueDate=date_add(DueDate,interval 1 day); Query OK, 4 rows affected (0.21 sec) Rows matched: 4 Changed: 4 Warnings: 0
Let us check the table records once again.
mysql> select *from DemoTable;
This will produce the following output −
+------------+ | DueDate | +------------+ | 2019-01-22 | | 2019-01-01 | | 2018-12-31 | | 2017-02-27 | +------------+ 4 rows in set (0.00 sec)
