分區表並獲取谷歌大查詢中的第一個和最後一個記錄

從下表中我試圖找到每個Id1的開始時間和停止時間。例如，對於Id1 = 103，它開始於2016-11-01 10:50:28 UTC，同一天的車輛停止時間爲2016-11-01 11:23:55 UTC。類似於id1 = 103，在2016-12-01，開始於2016-12-01 10:51:28 UTC，於2016-12-01 11:28:55結束。分區表並獲取谷歌大查詢中的第一個和最後一個記錄

我試着用下面的查詢，但不知道爲什麼它不工作：

  SELECT Id1, Date, StartTime, StopTime 
      FROM(
      SELECT 
      Id1, 
      DATE(DateTime) AS Date, 
      FIRST_VALUE(StartTime) OVER (PARTITION BY Id1, DATE(DateTime) ORDER BY DateTime) AS StartTime, 
      LAST_VALUE(StopTime) OVER (PARTITION BY Id1, DATE(DateTime) ORDER BY DateTime ROWS BETWEEN CURRENT ROW AND UNBOUNDED FOLLOWING) AS StopTime, 
      FROM 
      TestSridevi.ET_Time_Leaving) 
      GROUP BY Id1, Date, StartTime, StopTime 
      ORDER BY Id1
