How to add 1 day to the date in MySQL?

We can add 1 day to the date with the help of DATE_ADD() function.

Creating a table.

mysql> create table Add1DayDemo
   -> (
   -> id int,
   -> MyDate datetime not null
   -> );
Query OK, 0 rows affected (1.06 sec)

Insert some records.

mysql> insert into Add1DayDemo values(1,now());
Query OK, 1 row affected (0.08 sec)

mysql>   insert into Add1DayDemo values(2,date_add(now(),interval 5 day));
Query OK, 1 row affected (0.16 sec)

To display all records.

mysql> select *from Add1DayDemo;

The following is the output.

+------+---------------------+
| id   | MyDate              |
+------+---------------------+
|    1 | 2018-10-30 10:51:21 |
|    2 | 2018-11-04 10:51:30 |
+------+---------------------+
2 rows in set (0.00 sec)

To add 1 day in field “MyDate”, use the SELECT

mysql> SELECT DATE_ADD(`MyDate`, INTERVAL 1 DAY) from Add1DayDemo
    ->  where id=2;

The following is the output that shows the day, which was 4th November, increments by one, since we added a day.

+------------------------------------+
| DATE_ADD(`MyDate`, INTERVAL 1 DAY) |
+------------------------------------+
| 2018-11-05 10:51:30                |
+------------------------------------+
1 row in set (0.00 sec)
