我有字符串格式的时间 00:07:35.000000。 如何在 bigquery 中将其更改为时间格式？

Question

SELECT ride_time, CAST (ride_time as INTERVAL) as ride_time_hr

ride_time -> str 00:07:35.000000

I am expecting 00:07:35

You can use the PARSE_TIME function:

SELECT ride_time, PARSE_TIME("%H:%M:%E*S", ride_time) as ride_time_hr

Output:
