如何在 BigQuery 中使用“Mon May 11 2020 11:22:19 GMT+0000（协调世界时）”作为日期

Question

Is it possible to make a query to convert "Mon May 11 2020 11:22:19 GMT+0000 (Coordinated Universal Time)" to a date format such as YYYY-MM-DD within BigQuery?

Or the data format has to be converted before querying in BigQuery?

Answer 1

Below for BigQuery Standard SQL

SELECT DATE(PARSE_TIMESTAMP('%a %b %d %Y %X GMT%z', SUBSTR("Mon May 11 2020 11:22:19 GMT+0000 (Coordinated Universal Time)", 1, 33)))   

with output

2020-05-11

Answer 2

You can use this resource:

SELECT CURRENT_DATE([time_zone])

Returns: 2016-12-25

You can add an optional time zone as an argument to this function. It will return date in UTC time zone if you don't pass the argument.
