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 00:00:00.000
Adds negative two days to the specified date. 
SELECT DATE_ADD('2022-01-01', CAST(-2 AS INTERVAL DAY))
-- 2021-12-30 00:00:00.000

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 00:00:00.000

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 00:00:00.000
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 00:00:00.000

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. 
SELECT DATE_ADD(TIMESTAMP '2022-01-01 12:00:00', CAST(30 AS INTERVAL DAY))
-- 2022-01-31 12:00:00.000
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 12:00:00.000

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))
-- 00:30:00.000
Adds negative 30 minutes to the specified time. 
SELECT DATE_ADD(TIME '00:00:00', CAST(-30 AS INTERVAL MINUTE))
-- 23:30:00.000
