MariaDB: ADDDATE Function

This MariaDB tutorial explains how to use the MariaDB ADDDATE function with syntax and examples.

Description

The MariaDB ADDDATE function returns a date after which a certain time/date interval has been added.

Syntax

The syntax for the ADDDATE function in MariaDB is:

ADDDATE( date, INTERVAL value unit )

OR

ADDDATE( date, days )

Parameters or Arguments

date
The date to which the interval should be added.
days
The number of days to add to date (second syntax).
value
The value of the time/date interval that you wish to add. You can specify positive and negative values for this parameter (first syntax).
unit

The unit type of the interval such as DAY, MONTH, MINUTE, HOUR, and so on. It can be one of the following (first syntax):

unit
MICROSECOND
SECOND
MINUTE
HOUR
DAY
WEEK
MONTH
QUARTER
YEAR
SECOND_MICROSECOND
MINUTE_MICROSECOND
MINUTE_SECOND
HOUR_MICROSECOND
HOUR_SECOND
HOUR_MINUTE
DAY_MICROSECOND
DAY_SECOND
DAY_MINUTE
DAY_HOUR
YEAR_MONTH

Note

  • If you specify an interval value that is too short for the unit that you have specified, the ADDDATE function will assume that the left-most portion of the interval value was not provided.
  • The ADDDATE function (first syntax only) is a synonym for the DATE_ADD function.
  • Using the ADDDATE function with a negative value as a parameter is equivalent to using the SUBDATE function.
  • See also the DATE_ADD, DATE_SUB, SUBDATE, ADDTIME, and SUBTIME functions.

Applies To

The ADDDATE function can be used in the following versions of MariaDB:

  • MariaDB 10
