語法錯誤：應為“)”但在 [2:93] 處獲得了關鍵字 NEW

Question

任何人都可以幫助我如何更改我的查詢嗎？ 我是 BigQuery 的新手

  with W as (
        select COALESCE(UNIX_TIMESTAMP(startTime) - UNIX_TIMESTAMP(LAG(startTime, 1) over UW) > 1000, 1) new
             , W.startTime
             , W.id
             , W.user
        from Workout W
        window UW AS (partition by W.user order by W.startTime)
    )
    select SUM(new) OVER (order by W.user, W.startTime) pseudoSession
         , W.id
         , W.startTime
         , W.user
    from W;

由於new是保留關鍵字，您可能打算這樣做：

with W as (
    select COALESCE(UNIX_TIMESTAMP(startTime) - UNIX_TIMESTAMP(LAG(startTime, 1) over UW) > 1000, 1) `new`
         , W.startTime
         , W.id
         , W.user
    from Workout W
    window UW AS (partition by W.user order by W.startTime)
)
select SUM(new) OVER (order by W.user, W.startTime) pseudoSession
     , W.id
     , W.startTime
     , W.user
from W;

或者，也可以使用其他一些非保留字。
