Question

我正在尝试为在会话期间完成特定事件操作的用户创建用户页面路径分析。到目前为止，我已经能够为所有用户创建页面路径-但是我现在正在尝试为联系的用户创建辅助路径分析。

我尽力使用where子句查找解决方案，但所有结果均显示0个结果

SELECT t.page_path,
        t.second_page_path,
        t.third_page_path,
        t.fourth_page_path,
        #concact the 4 pages together with a hyphen if a next page exists
        CONCAT(t.page_path,IF(t.second_page_path IS NULL,'','*'),
        IFNULL(t.second_page_path,''),IF(t.third_page_path IS NULL,'','*'),
        IFNULL(t.third_page_path,''),IF(t.fourth_page_path IS NULL,'','*'),
        IFNULL(t.fourth_page_path,'')) AS full_page_journey,
        #Count total sessions that went down that path after landing
        count(sessionId) AS total_sessions
FROM (
SELECT
  CONCAT(fullVisitorId,'-', CAST(visitStartTime AS STRING)) AS sessionId,
  hits.hitNumber as hitsya,
 (SELECT x.value FROM UNNEST(hits.customDimensions) x WHERE x.index = 22) as page_path,  
  LEAD((SELECT x.value FROM UNNEST(hits.customDimensions) x WHERE x.index = 22)) OVER (PARTITION BY fullVisitorId, visitStartTime ORDER BY hits.hitNumber) AS second_page_path,
  LEAD((SELECT x.value FROM UNNEST(hits.customDimensions) x WHERE x.index = 22),2) OVER (PARTITION BY fullVisitorId, visitStartTime ORDER BY hits.hitNumber) AS third_page_path,
  LEAD((SELECT x.value FROM UNNEST(hits.customDimensions) x WHERE x.index = 22),3) OVER (PARTITION BY fullVisitorId, visitStartTime ORDER BY hits.hitNumber) AS fourth_page_path
FROM
  `PROJECT_NAME.ga_sessions_*`,
  UNNEST(hits) AS hits
WHERE
  _TABLE_SUFFIX BETWEEN '20190501'
  AND '20190505'
  AND hits.type='PAGE'
  AND REGEXP_CONTAINS(hits.eventInfo.eventAction, r'Contact Us Submission'))t
 WHERE t.hitsya=1
     #Group by page of hit and all subsequent pages
     GROUP BY t.page_path,
              t.second_page_path,
              t.third_page_path,
              t.fourth_page_path,
              full_page_journey
     ORDER BY total_sessions DESC

我希望只能获得包含该事件的会话

Answer 1

由于您的条件矛盾，您得到0个结果：

WHERE
  _TABLE_SUFFIX BETWEEN '20190501'
  AND '20190505'
  AND hits.type='PAGE'
  AND REGEXP_CONTAINS(hits.eventInfo.eventAction, r'Contact Us Submission'))t

您不能拥有hits.type='PAGE'，并且不能期望hits.eventInfo.eventAction中的值。该字段仅包含hits.type='EVENT'

的值

如果您希望与此事件进行会话，则在整个会话中使用子查询来查找它：

WHERE
  _TABLE_SUFFIX BETWEEN '20190501'
  AND '20190505'
  AND hits.type='PAGE'
  AND (SELECT COUNT(1)>0 
   FROM unnest(hits) 
   WHERE REGEXP_CONTAINS(hits.eventInfo.eventAction, r'Contact Us Submission') )

在BigQuery中创建高级细分
