加入日期分区表给出“'the_date' is not present in the GROUP BY list”错误

Question

通过answer in mind，我正在尝试查询 ga_sessions，在加入我自己的自定义报告计划后汇总一些基本指标。自定义报告计划将自定义期间（大约 4 周）映射到日期格式 YYYYMMDD 并在其自己的表格中。

这是我想出的：

SELECT
  schedule.period,
  gadata.Visits,
  gadata.Pageviews,
  gadata.Transactions,
  gadata.Revenue
FROM (
  SELECT 
    gadata.date AS the_date, 
    SUM(totals.visits) AS Visits, 
    SUM(totals.pageviews) AS Pageviews,
    SUM(totals.transactions) AS Transactions, 
    SUM(totals.transactionRevenue)/1000000 AS Revenue
  FROM TABLE_DATE_RANGE([project.table_prefix_],TIMESTAMP('2013-09-10'),TIMESTAMP('2013-09-12'))
  GROUP BY
    gadata.the_date
  ORDER BY
    gadata.the_date ASC
) AS gadata
JOIN 
  [project.reporting_schedule] AS schedule
ON
  gadata.date = schedule.GA_Date
GROUP BY gadata.the_date

但这给出了错误：“错误：GROUP BY 列表中不存在表达式'the_date'”

我强烈怀疑我对语法的使用有问题，我对 Google Big Query 很陌生，查询日期分区表和连接的组合让我很吃惊。

我需要更改哪些内容才能更正代码并按自定义期间汇总指标？

您遇到了多个问题。首先是 Table 日期范围函数不能使用别名，因此您需要包装成一个 select 以进一步使用别名。

我用静态写法替换了scheduled表，但是你可以用自己的select field from table语法替换

SELECT
  the_date,
  SUM(totals.visits) AS Visits,
  SUM(totals.pageviews) AS Pageviews,
  SUM(totals.transactions) AS Transactions,
  SUM(totals.transactionRevenue)/1000000 AS Revenue
FROM (
  SELECT
    [date] AS the_date,
    totals.visits,
    totals.pageviews,
    totals.transactions,
    totals.transactionRevenue
  FROM
    TABLE_DATE_RANGE([google.com:analytics-bigquery:LondonCycleHelmet.ga_sessions_],TIMESTAMP('2013-09-10'),TIMESTAMP('2013-09-12')) ) tt
JOIN (
  SELECT * FROM (SELECT '20130910' AS report_date), (SELECT '20130911' AS report_date)) schedule
ON
  schedule.report_date = tt.the_date
GROUP BY
  1

返回：

+-----+----------+--------+-----------+--------------+---------+---+
| Row | the_date | Visits | Pageviews | Transactions | Revenue |   |
+-----+----------+--------+-----------+--------------+---------+---+
|   1 | 20130910 |     63 |       249 |           16 | 206.23  |   |
