Question

我正在执行以下查询。

SELECT properties.os, boundary, user, td,
  SUM(boundary) OVER(ORDER BY rows) AS session
FROM
  (
  SELECT properties.os, ROW_NUMBER() OVER() AS rows, user, td,
    CASE WHEN td > 1800 THEN 1 ELSE 0 END AS boundary
  FROM (
    SELECT properties.os, t1.properties.distinct_id AS user,
      (t2.properties.time - t1.properties.time) AS td
    FROM (
      SELECT properties.os, properties.distinct_id, properties.time, srlno,
        srlno-1 AS prev_srlno
      FROM (
        SELECT properties.os, properties.distinct_id, properties.time,
          ROW_NUMBER()
        OVER (PARTITION BY properties.distinct_id
          ORDER BY properties.time) AS srlno
        FROM [ziptrips.ziptrips_events]
        WHERE properties.time  > 1367916800
          AND properties.time < 1380003200)) AS t1
    JOIN (
      SELECT properties.distinct_id, properties.time, srlno,
        srlno-1 AS prev_srlno
      FROM (
        SELECT properties.distinct_id, properties.time,
          ROW_NUMBER() OVER
          (PARTITION BY properties.distinct_id ORDER BY properties.time) AS srlno
        FROM [ziptrips.ziptrips_events]
        WHERE
          properties.time  > 1367916800
          AND properties.time < 1380003200 )) AS t2
    ON t1.srlno  = t2.prev_srlno
      AND t1.properties.distinct_id = t2.properties.distinct_id
    WHERE (t2.properties.time - t1.properties.time) > 0))

第一次失败并出现以下错误。但是在第二次运行时它完成没有任何问题。我对任何可能导致这种情况的指示表示赞赏。

错误消息是：查询失败错误：在表'__R2'中找不到字段'properties.os'。工作ID：job_VWunPesUJVLxWGZsMgpoti14BM4

我们（BigQuery团队）正在推出新版本的查询引擎，修复了许多问题。您可能点击旧版本的查询引擎，然后在重试时点击新版本。我们可能需要一天左右的时间，一部分流量指向更新后的版本，以确认没有任何回归。如果您在24小时后再次发现此消息，请告诉我们。
