Question

我有以下SQL语句，简而言之，table包含我需要获取过去一年网站行为的id列表。这些id应与customDimensions.value

匹配

SELECT fullVisitorId, visitNumber, totals.pageviews, customDimensions.value as client_id
FROM (
SELECT * FROM
  TABLE_DATE_RANGE([xxxxxxx.ga_sessions_],
                    TIMESTAMP('2017-01-01'),
                    TIMESTAMP('2018-01-01'))
                    )
WHERE customDimensions.index = 2 AND customDimensions.value IN (SELECT STRING(id) FROM [table])
GROUP BY 1,2,3,4

我收到错误：

错误：无法加入重复字段customDimensions.value

我发现你仍然使用BigQuery Legacy SQL，所以下面是遗留sql

假设原始查询的其余部分符合您的要求 - 它会解决以下错误

错误：无法加入重复字段customDimensions.value

#legacySQL
SELECT fullVisitorId, visitNumber, totals.pageviews, customDimensions.value AS client_id
FROM FLATTEN((
SELECT * FROM
  TABLE_DATE_RANGE([xxxxxxx.ga_sessions_],
                    TIMESTAMP('2017-01-01'),
                    TIMESTAMP('2018-01-01'))
                    ), customDimensions)
WHERE customDimensions.index = 2 AND customDimensions.value IN (SELECT STRING(id) FROM [table])
GROUP BY 1,2,3,4

BiqQuery错误：无法加入重复字段'customDimensions.value'
