This article introduces how to get the current time in MySQL the day before and the day after. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

MySQL adds a time interval to the date with the date_add () function

MySQL subtracts a time interval from the date using the date_sub () function

The experiments are as follows:

Mysql > select now ()

+-+

| | now () |

+-+

| | 2017-03-15 16:57:30 |

+-+

1 row in set (0.00 sec)

Mysql > set @ dt = now ()

Query OK, 0 rows affected (0.00 sec)

Add one day:

Mysql > select date_add (@ dt, interval 1 day)

+-+

| | date_add (@ dt, interval 1 day) | |

+-+

| | 2017-03-16 16:57:32 |

+-+

1 row in set (0.00 sec)

One day less:

Mysql > select date_sub (@ dt, interval 1 day)

+-+

| | date_sub (@ dt, interval 1 day) | |

+-+

| | 2017-03-14 16:57:32 |

+-+

1 row in set (0.00 sec)

By the same token, an additional hour and a minute can be used:

Select date_add (@ dt, interval 1 hour);-- add one hour

Select date_add (@ dt, interval 1 minute);-- add one minute

Select date_add (@ dt, interval 1 second);-- add one second

Select date_add (@ dt, interval 1 microsecond);-- add a nuance

Select date_add (@ dt, interval 1 week);-- add one week

Select date_add (@ dt, interval 1 month);-- add one month

Select date_add (@ dt, interval 1 quarter); add one quarter (three months)

One hour less, one minute can be used:

Select date_sub (@ dt, interval 1 hour);-- one hour less

Select date_sub (@ dt, interval 1 minute);-- one minute less

Select date_sub (@ dt, interval 1 second);-- one second less

Select date_sub (@ dt, interval 1 microsecond);-- reduce a little bit

Select date_sub (@ dt, interval 1 week);-- one week less

Select date_sub (@ dt, interval 1 month);-- one month less

Select date_sub (@ dt, interval 1 quarter);-reduced by one quarter (three months)
