获取日期等于或大于 90 天前的数据

Question

I wonder if anyone here can help with a BigQuery piece I am working on. I'm trying to pull the date, email and last interaction time from a dataset when the last interaction time is equal to or greater than 90 days ago.

I have the following query:

SELECT
  date,
  user_email,
  DATE_FROM_UNIX_DATE(gmail.last_interaction_time) AS Last_Interaction_Date,
  DATE_ADD(CURRENT_DATE(), INTERVAL -90 DAY) AS Days_ago
FROM
  `bqadminreporting.adminlogtracking.usage`
WHERE
  'Last_Interaction_Date' >= 'Days_ago'

However, I run into the following error:

DATE value is out of allowed range: from 0001-01-01 to 9999-12-31

As far as I can see, it makes sense - so not entirely sure why its throwing out an error?

Answer 1

Looks like you have some inconsistent values (data) in filed gmail.last_interaction_time , which you need to handle to avoid error.

Moreover above query will not work as per your expected WHERE conditions, you should use following query to get expected output.

SELECT * FROM
(SELECT
  date,
  user_email,
  DATE_FROM_UNIX_DATE(gmail.last_interaction_time) AS Last_Interaction_Date,
  DATE_ADD(CURRENT_DATE(), INTERVAL -90 DAY) AS Days_ago
FROM
  `bqadminreporting.adminlogtracking.usage`)
WHERE
  Last_Interaction_Date >= Days_ago

Answer 2

Presumably, your problem is DATE_FROM_UNIX_DATE() . Without sample data, it is not really possible to determine what the issue is.

However, you don't need to convert to a date to do this. You can do all the work in the Unix seconds space:

select u.*
from `bqadminreporting.adminlogtracking.usage` u
where gmail.last_interaction_time >= unix_seconds(timestamp(current_date)) - 90 * 60 * 60 * 24

Note that I suspect that the issue is that last_interaction_time is really measured in milliseconds or microseconds or some other unit. This will prevent your error, but it might not do what you want.
