我有一个查询：
WITH DAY_WIDGET_STAT AS (
SELECT hits.eventInfo.eventCategory, hits.eventInfo.eventAction, hits.eventInfo.eventLabel, hits.page.pagePath
FROM `api-open-broker.108613784.ga_sessions_20181125`, UNNEST(hits) as hits
WHERE hits.type='EVENT' and hits.eventInfo.eventCategory LIKE "%Widget%"
),
DAY_PAGEVIEWS_STAT AS (
SELECT hits.page.pagePath, COUNT(*) AS pageviews
FROM `api-open-broker.108613784.ga_sessions_20181125`,UNNEST(hits) AS hits
WHERE hits.type = 'PAGE' GROUP BY hits.page.pagePath ORDER BY pageviews DESC)
SELECT *
FROM DAY_WIDGET_STAT INNER JOIN DAY_PAGEVIEWS_STAT ON DAY_WIDGET_STAT.pagePath=DAY_PAGEVIEWS_STAT.pagePath
LIMIT 10
这给了我“不支持结果中的重复列名。找到重复项：pagePath”。为什么？表DAY_WIDGET_STAT： 外观 DAY_PAGEVIEWS_STAT： 外观
