Question

我想检索在访问分割日期内有自定义尺寸匹配的访问量。我在这个查询的帮助下得到这些数据作为所有选定日期的总和，但是如何按日期分割它？

非常感谢提前！

select sum(sessions) as total_sessions, from (
  select
    fullvisitorid,
    count(distinct visitid) as sessions,
    from (TABLE_DATE_RANGE([XXX.ga_sessions_], TIMESTAMP('2016-09-01'), TIMESTAMP('2016-09-03')))
    where totals.visits = 1
AND hits.customDimensions.index = 3 
AND hits.customDimensions.value = 'play'
    group each by fullvisitorid
)

Answer 1

您可以使用standard SQL在桌面上尝试此操作（取消选中“显示选项”下的“使用旧版SQL”）吗？我可能误解了这个问题，但它计算了每天与customDimensions条件相匹配的总访问次数，我相信这就是你想要的。

SELECT
  _PARTITIONTIME,
  COUNTIF(EXISTS (SELECT 1 FROM UNNEST(hits), UNNEST(customDimensions)
                  WHERE index = 3 AND value = 'play')) as sessions
FROM `XXX.ga_sessions_*`
WHERE totals.visits = 1
GROUP BY _PARTITIONTIME;

Answer 2

ga_sessions表包含date字段（请参阅Analytics to BigQuery Export schema）

因此，如果您希望继续使用BigQuery Legacy SQL进行上述查询，则可以使用此date字段，如下例所示

SELECT date, SUM(sessions) AS total_sessions FROM (
  SELECT
    date, 
    fullvisitorid,
    COUNT(DISTINCT visitid) AS sessions
  FROM (TABLE_DATE_RANGE([XXX.ga_sessions_], TIMESTAMP('2016-09-01'), TIMESTAMP('2016-09-03')))
  WHERE totals.visits = 1
  AND hits.customDimensions.index = 3 
  AND hits.customDimensions.value = 'play'
  GROUP BY date, fullvisitorid
)
GROUP BY date

如果您可以/希望Migrate from BigQuery Legacy SQL到BigQuery Standard SQL，您可以使用以下示例：

SELECT
  _TABLE_SUFFIX AS date,
  COUNTIF(EXISTS (SELECT 1 FROM UNNEST(hits), UNNEST(customDimensions)
                  WHERE TRUE OR (index = 3 AND value = 'play'))) AS sessions
FROM `XXX.ga_sessions_*`
WHERE totals.visits = 1
AND _TABLE_SUFFIX BETWEEN '2016-09-01' AND '2016-09-03'
GROUP BY date
