迄今為止的大查詢字符串

Question

如何在 Big Query 中使用parse_timestamp將字符串轉換為日期？

"2022-12-12T14:17:41.9626+03:00"

我需要以下內容；

date(timestamp(parse_datetime("%Y-%m-%dT%H:%M:%SZ", receivedAt)))

Answer 1

似乎已經是TIMESTAMP literals ，因此您可以在下面考慮。

WITH sample_table AS (
  SELECT "2022-12-12T14:17:41.9626+03:00" received_at
)
SELECT EXTRACT(DATE FROM TIMESTAMP(received_at)) received_dt
  FROM sample_table;

+-----+-------------+
| Row | received_dt |
+-----+-------------+
|   1 | 2022-12-12  |
+-----+-------------+
