你能帮我把这个查询转换成 BigQuery 的标准 sql 吗？我收到此错误无法访问 hits.page.hostname LIKE 'website.fr' 中类型为 ARRAY> 的值的字段页面。请告诉我处理该问题以纠正它。

#standardSQL
SELECT DATE,MAX(CASE
  WHEN customDimensions.index = 1 THEN customDimensions.value END) AS CUSTOMDIMENSIONS_VALUE,  visitNumber,  fullvisitorid,  visitStartTime,  SEC_TO_TIMESTAMP(visitStartTime) AS humain,  TIME (visitStartTime+3600 ) AS Paris_timezone,  hits.hour,  hits.minute,  CONCAT(fullvisitorid, STRING(visitid)) AS sessionid,  MAX(CASE
  WHEN hits.customDimensions.index = 11 THEN hits.customDimensions.value END) AS localproductname,

hits.page.pagePath,
IFNULL(hits.page.pagePathLevel2,'') AS HITS_PAGE_PAGEPATHLEVEL2,

我在查询中发现了几个错误。我已经更正了，希望对你有帮助。

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

CROSS JOIN UNNEST(customDimensions) AS customDimensions

在您的查询中，您为hit返回的元素提供别名UNNEST(hits)，并为返回customDimension的元素提供别名UNNEST(customDimensions)。如果要引用特定匹配而不是数组，hit请改用，如果要引用单个自定义维度，请customDimension改用。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)
