有谁知道如何同时使用多个FLATTEN函数和Table_date_range?现在我只能获得一天的数据,但我希望获得所有可用的数据。有办法吗?
select
Date,COUNT(DISTINCT FULLVISITORID),hits.product.v2ProductCategory
FROM FLATTEN((FLATTEN (table, hits.product.v2ProductCategory)) ,customDimensions.value)
group by Date
,hits.product.v2ProductCategory
谢谢

您应该使用标准SQL。例如,
#standardSQL
SELECT
Date,
COUNT(DISTINCT FULLVISITORID),
product.v2ProductCategory,
customDimension.value
FROM `aaprod-20160309.112099209.ga_sessions_*` AS t
CROSS JOIN UNNEST(hits) AS hit
CROSS JOIN UNNEST(t.customDimensions) AS customDimension
CROSS JOIN UNNEST(hit.product) AS product
GROUP BY 1, 3, 4;
遗留标准SQL与标准SQL之间的差异在migration guide。

尝试以下(未测试)
SELECT
DATE,
COUNT(DISTINCT FULLVISITORID),
hits.product.v2ProductCategory
FROM FLATTEN(FLATTEN (
(SELECT *
FROM TABLE_DATE_RANGE([aaprod-20160309:112099209.ga_sessions_],
TIMESTAMP('2016-07-25'),
TIMESTAMP('2016-07-27'))
), hits.product.v2ProductCategory), customDimensions.value
)
GROUP BY
DATE,
hits.product.v2ProductCategory
