Question

你可以帮我解决这个问题，在标准的SQL for BigQuery中转换这个查询吗？我收到此错误无法访问类型为ARRAY＆gt;的值的字段页面at hits.page.hostname LIKE'weite.fr'。请告诉我处理该问题以纠正它。

Answer 1

在您的查询中，您将别名hit提供给UNNEST(hits)返回的元素，将别名customDimension提供给UNNEST(customDimensions)返回的元素。如果您想引用特定匹配而不是数组，请改用hit，如果您想引用单个自定义维度，请改用customDimension。例如，您的过滤器可能类似于：

WHERE _TABLE_SUFFIX BETWEEN '20161025' AND '20161026' AND
  hit.page.hostname LIKE '%website.fr%' AND
  customDimension.value != "null" AND
  hit.page.pagePath LIKE '%poiu%' AND
  hit.type = 'PAGE' AND
  customDimension.index IN (1, 11, 14, 27)

Answer 2

我在查询中发现了几个错误。我做了更正，希望这对你有帮助。

SELECT DATE,MAX(CASE
  WHEN customDimensions.index = 1 THEN customDimensions.value END) AS CUSTOMDIMENSIONS_VALUE,  visitNumber,  fullvisitorid,  visitStartTime, TIMESTAMP_SECONDS(visitStartTime) AS humain, EXTRACT(DATE FROM TIMESTAMP_SECONDS(visitStartTime) AT TIME ZONE 'Paris_timezone')  AS Paris_timezone, 
  hits.hour,  hits.minute,  CONCAT(CAST(fullVisitorId AS string),CAST(visitId AS string)) AS sessionid,  MAX(CASE
  WHEN customDimensions.index = 11 THEN customDimensions.value END) AS localproductname,
device.deviceCategory,
hits.page.pagePath,
IFNULL(hits.page.pagePathLevel2,'') AS HITS_PAGE_PAGEPATHLEVEL2,
IFNULL(hits.page.pagePathLevel3,'') AS HITS_PAGE_PAGEPATHLEVEL3,
MAX(CASE WHEN customDimensions.index = 14 THEN customDimensions.value END) AS assetpurpose,
MAX(CASE WHEN customDimensions.index = 27 THEN customDimensions.value END) AS pathology,
hits.hitNumber
FROM `85801771.ga_sessions*`
CROSS JOIN UNNEST(customDimensions) AS customDimensions
CROSS JOIN UNNEST(hits) AS hits

  AND hits.page.pagePath LIKE 'poiu'
  AND hits.type = 'PAGE'
  AND (customDimensions.index = 1
  OR customDimensions.index = 11
  OR customDimensions.index = 14
  OR customDimensions.index = 27 )
GROUP BY

BigQuery：用于查询表的standard-sql错误？
