BigQuery where date is less than or equal to 3 days minus the current date

I am trying to create a query to return data only where the date is minus 3 days from the current date. I tried:

date <= DATE_ADD(CURRENT_DATE(), -3, 'DAY')

But this returns Error: Expected INTERVAL expression

+3

See the WHERE clause in the example below

#standardSQL
WITH yourTable AS (
  SELECT i, date
  FROM UNNEST(GENERATE_DATE_ARRAY('2017-04-15', '2017-04-28')) AS date WITH OFFSET AS i
)
SELECT *
FROM yourTable
WHERE date <= DATE_SUB(CURRENT_DATE(), INTERVAL 3 DAY)
-- ORDER BY date


Btw if you are still using Legacy SQL - see below example

#legacySQL
SELECT *
FROM -- yourTable  
  (SELECT 1 AS id, DATE('2017-04-20') AS date),
  (SELECT 2 AS id, DATE('2017-04-21') AS date),
  (SELECT 3 AS id, DATE('2017-04-22') AS date),
  (SELECT 4 AS id, DATE('2017-04-23') AS date),
  (SELECT 5 AS id, DATE('2017-04-24') AS date),
  (SELECT 6 AS id, DATE('2017-04-25') AS date)
WHERE TIMESTAMP(date) <= DATE_ADD(TIMESTAMP(CURRENT_DATE()), -3, 'DAY')
-- ORDER BY date
+5

This works with a date formatted string.



DATE(TIMESTAMP(date)) <= DATE_SUB(CURRENT_DATE(), INTERVAL 3 DAY)

+1
