DATE_ADD

Returns the sum of two expressions of time as another expression of time.

Syntax

DATE_ADD(date_expression string, days integer) → date

• date_expression: A string-formatted date in the format ‘YYYY-MM-DD’.

• days: The number of days to be added to the specified date.

Examples

Adds two days to the specified date.

SELECT DATE_ADD('2022-01-01', 2)
-- 2022-01-03

Adds negative two days to the specified date.

SELECT DATE_ADD('2022-01-01', -2)
-- 2021-12-30

DATE_ADD(date_expression date, days integer) → date

• date_expression: The date, in the format ‘YYY-MM-DD’, to add days to. The value can be either a database column in DATE format, or literal value explicitly converted to DATE.

• days: A 32-bit integer of the number of days to be added to the specified date.

Examples

Adds 30 days to the specified date.

SELECT DATE_ADD(DATE '2022-01-01', 30)
-- 2022-01-31

Adds negative 30 days to the specified date.

SELECT DATE_ADD(DATE '2022-01-01', -30)
-- 2021-12-02

DATE_ADD(date_expression string, time_interval interval) → timestamp

• date_expression: A string-formatted date in the format ‘YYYY-MM-DD’.

• time_interval: A CAST of a number to one of these intervals: DAY, MONTH, YEAR.

Examples

Adds two days to the specified date.

SELECT DATE_ADD('2022-01-01', CAST(2 AS INTERVAL DAY))
-- 2022-01-03 00:00:00

Adds negative two days to the specified date.

SELECT DATE_ADD('2022-01-01', CAST(-2 AS INTERVAL DAY))
-- 2021-12-30 00:00:00

DATE_ADD(date_expression date, time_interval interval) → timestamp

• date_expression: The date, in the format ‘YYY-MM-DD’, to add the time interval to. The value can be either a database column in DATE format, or literal value explicitly converted to DATE.

• time_interval: A CAST of a number to one of these intervals: DAY, MONTH, YEAR.

Examples

DATE_ADD example

SELECT DATE_ADD(DATE '2022-01-01', CAST(30 AS INTERVAL DAY))
-- 2022-01-31 00:00:00

DATE_ADD(timestamp_expression string, time_interval interval) → timestamp

• timestamp_expression: A string-formatted timestamp in the format ‘YYYY-MM-DD HH24:MI:SS’.

• time_interval: A CAST of a number to one of these intervals: SECOND, MINUTE, HOUR, DAY, MONTH, YEAR.

Examples

Adds 30 days to the specified timestamp. Note that the time information is lost.

SELECT DATE_ADD('2022-01-01 12:00:00', CAST(30 AS INTERVAL DAY))
-- 2022-01-31 00:00:00

Adds negative 30 days to the specified timestamp. Note that the time information is lost.

SELECT DATE_ADD('2022-01-01 12:00:00', CAST(-30 AS INTERVAL DAY))
-- 2021-12-02 00:00:00

DATE_ADD(timestamp_expression timestamp, time_interval interval) → timestamp

• timestamp_expression: The timestamp, in the format ‘YYYY-MM-DD HH:MM:SS’, to add days to. The value can be either a database column in TIMESTAMP format, or literal value explicitly converted to TIMESTAMP.

• time_interval: A CAST of a number to one of these intervals: SECOND, MINUTE, HOUR, DAY, MONTH, YEAR.

Examples

Adds 30 days to the specified timestamp.

Adds 30 days to the specified timestamp.

SELECT DATE_ADD(TIMESTAMP '2022-01-01 12:00:00', CAST(30 AS INTERVAL DAY))
-- 2022-01-31 12:00:00

Adds negative 30 days to the specified timestamp.

SELECT DATE_ADD(TIMESTAMP '2022-01-01 12:00:00', CAST(-30 AS INTERVAL DAY))
-- 2021-12-02 12:00:00

DATE_ADD(time_expression time, time_interval interval) → time

• time_expression: The time, in the format ‘HH:MM:SS’, to add the time interval to. The value can be either a database column in TIMESTAMP format, or literal value explicitly converted to TIMESTAMP.

• time_interval: A CAST of a number to one of these intervals: SECOND, MINUTE, HOUR.

Examples

Adds 30 minutes to the specified time.

SELECT DATE_ADD(TIME '00:00:00', CAST(30 AS INTERVAL MINUTE))
-- 00:30:00

Adds negative 30 minutes to the specified time.

SELECT DATE_ADD(TIME '00:00:00', CAST(-30 AS INTERVAL MINUTE))
-- 84600
