在 BigQuery SQL 查询的数据集中创建永久 table 的语法是什么？

Question

问题总结：

我有一个临时的 table 作为我查询的结果，以便通过使用 WITH 语句合并 12 个月的数据。我可以保存温度。 table 通过将视图保存为永久视图手动 table 然后我将其导出以在我的可视化应用程序中使用。

我想知道添加到我的查询中的适当语法，以便该过程运行无缝。

描述您尝试过的内容：

我尝试使用 CREATE TABLE、EXECUTE IMMEDIATE（concat...等），但出现错误。

在适当的时候，显示一些代码：

能否请您与我分享可能的正确代码以添加到我的以下查询中（我缩短了代码） temptable 作为我的临时 table。说 permtable 是我的永久 table as project.data_set.permtable

谢谢。

WITH

  temptable AS ( 
        
        #May 2021
  SELECT
    ride_id,
    rideable_type,
    CAST(started_at AS TIMESTAMP ) AS started_at,
    CAST(ended_at AS TIMESTAMP ) AS ended_at,
    start_station_name,
    CAST(start_station_id AS STRING ) AS start_station_id,
    end_station_name,
    CAST(end_station_id AS STRING ) AS end_station_id,
    start_lat,
    start_lng,
    end_lat,
    end_lng,
    member_casual,
    timestamp_diff (ended_at,started_at, minute) AS trip_duration,
    EXTRACT(DAYOFWEEK FROM started_at) AS day_of_week
  FROM
    `project.data_set.table1`
  UNION ALL
    #June 2021
  SELECT
    ride_id,
    rideable_type,
    CAST(started_at AS TIMESTAMP ) AS started_at,
    CAST(ended_at AS TIMESTAMP ) AS ended_at,
    start_station_name,
    CAST(start_station_id AS STRING ) AS start_station_id,
    end_station_name,
    CAST(end_station_id AS STRING ) AS end_station_id,
    start_lat,
    start_lng,
    end_lat,
    end_lng,
    member_casual,
    timestamp_diff (ended_at,started_at, minute) AS trip_duration,
    EXTRACT(DAYOFWEEK FROM started_at) AS day_of_week
  FROM
    `project.data_set.table2` )

SELECT * FROM combined_rides
 WHERE
    NOT( start_station_id IS NULL
      OR end_station_id IS NULL
      OR start_lat IS NULL
      OR end_lat IS NULL
      OR start_station_name LIKE '%CHECKING%'
      OR end_station_name LIKE '%CHECKING%'
      OR trip_duration < 1 )

您可以使用 CREATE TABLE 语句来实现：

CREATE TABLE IF NOT EXISTS project.data_set.permtable
AS
WITH temptable AS (    
        #May 2021
  SELECT
    ride_id,
    rideable_type,
    CAST(started_at AS TIMESTAMP ) AS started_at,
    CAST(ended_at AS TIMESTAMP ) AS ended_at,
    start_station_name,
    CAST(start_station_id AS STRING ) AS start_station_id,
    end_station_name,
    CAST(end_station_id AS STRING ) AS end_station_id,
    start_lat,
    start_lng,
    end_lat,
    end_lng,
    member_casual,
    timestamp_diff (ended_at,started_at, minute) AS trip_duration,
    EXTRACT(DAYOFWEEK FROM started_at) AS day_of_week
  FROM
    `project.data_set.table1`
  UNION ALL
    #June 2021
  SELECT
    ride_id,
    rideable_type,
    CAST(started_at AS TIMESTAMP ) AS started_at,
    CAST(ended_at AS TIMESTAMP ) AS ended_at,
    start_station_name,
    CAST(start_station_id AS STRING ) AS start_station_id,
    end_station_name,
    CAST(end_station_id AS STRING ) AS end_station_id,
    start_lat,
    start_lng,
    end_lat,
    end_lng,
    member_casual,
    timestamp_diff (ended_at,started_at, minute) AS trip_duration,
    EXTRACT(DAYOFWEEK FROM started_at) AS day_of_week
  FROM
    `project.data_set.table2` )

SELECT * FROM combined_rides
 WHERE
    NOT( start_station_id IS NULL
      OR end_station_id IS NULL
      OR start_lat IS NULL
      OR end_lat IS NULL
      OR start_station_name LIKE '%CHECKING%'
      OR end_station_name LIKE '%CHECKING%'
      OR trip_duration < 1 );

好了，您现在将在指定的项目和数据集中有一个 permtable table！
