我想添加几个小时,例如:使用bigquery在5小时30分钟到时间戳字段。我的时间戳字段的格式为 - ' 2016-05-03 21:35:03'

我怎么能在bigquery中这样做?

为了完整性,等效standard SQL查询(取消选中"使用旧版SQL""显示选项")将是:

WITH T AS (
  SELECT ts
  FROM UNNEST([CURRENT_TIMESTAMP(),
               TIMESTAMP("2016-05-03 21:35:03")]) AS ts)
SELECT TIMESTAMP_ADD(ts, INTERVAL 330 MINUTE) AS ts_plus_530
FROM T;
+---------------------+
|     ts_plus_530     |
+---------------------+
| 2016-08-09 04:18:05 |
| 2016-05-04 03:05:03 |
+---------------------+

SELECT 
  ts, 
  DATE_ADD(ts, 330, "MINUTE") AS ts_plus_530 
FROM 
  (SELECT CURRENT_TIMESTAMP() AS ts),
  (SELECT TIMESTAMP("2016-05-03 21:35:03") AS ts)
