BigQuery：关于将时间添加为维度的问题

Question

我正在尝试将“时间”或“日期”作为维度添加到Big Query中的Google Analytics（分析）查询中...如何将每日或每月的“日期”添加到此查询中？我了解如何过滤WHERE语句中的日期，但不了解如何在显示的结果中添加“日期”字段。参见附带的代码。

错误的几个_TableSuffix选项

SELECT
  hits.page.pagePath, 
  COUNT(*) AS pageviews
FROM
  `xyz.33759344.ga_sessions_*` AS GA,
  UNNEST(GA.hits) AS hits
WHERE
  hits.type = 'PAGE'
  AND
_TABLE_SUFFIX BETWEEN '20190201' AND '20190331'
AND
hits.page.pagePath LIKE '%step/checkout'
GROUP BY
  hits.page.pagePath
ORDER BY
  pageviews DESC

我想将每天和（作为单独的查询）每月计数添加到代码中。

Answer 1

要按日期显示提示，您可以简单地按GROUP BY列日期。请参阅以下使用公共GA示例数据的示例。 （还请检查BigQuery Datetime Functions，了解如何从日期中提取月份）

#standardSQL
SELECT  hits.page.pagePath, 
  COUNT(*) AS pageviews, date
FROM
   `bigquery-public-data.google_analytics_sample.ga_sessions_*` AS GA,
  UNNEST(GA.hits) AS hits
WHERE
  hits.type = 'PAGE'
  AND
_TABLE_SUFFIX BETWEEN '20170701' AND '20170801'
AND
hits.page.pagePath LIKE '%/google+redesign/electronics'
GROUP BY
  hits.page.pagePath, date
ORDER BY
  pageviews DESC

结果如下：
