Google bigquery 如果一周从BigQuery中的星期一开始，如何获取当前一周的第一天？

我是大查询的初学者。上面的查询给了我一个错误，请帮我更正

错误消息：

SELECT TIMESTAMP_TRUNC(CURRENT_DATE(), WEEK(MONDAY)) AS FirstDayOfWeek

---

使用

DATE\u TRUNC

代替

TIMESTAMP\u TRUNC

No matching signature for function TIMESTAMP_TRUNC for argument types: DATE, DATE_TIME_PART. Supported signature: TIMESTAMP_TRUNC(TIMESTAMP, DATE_TIME_PART, [STRING]) at [1:8]

SELECT DATE_TRUNC(CURRENT_DATE(), WEEK(MONDAY)) AS FirstDayOfWeek
