BigQuery 中 Google Analytics 数据的 DoubleClick (DFP) 数据的唯一键？

Question

我为 BigQuery 设置了 DoubleClick（DFP/Google Ad Manager）数据和 Google Analytics 360 的每日导出。这些链接在我的 Google Analytics 帐户上，因此可以从分析 GUI 中查看广告管理器数据。

但是，当我查看会话数据时，似乎没有任何唯一键可以连接两个数据集。有没有办法在 bigquery 中加入这两个数据集？

您不需要使用相同的列名来连接表

with

transactions as (
    select
        *
    from
        unnest(
            array[
                struct(
                    'xxx' as pos_id,
                    1 as transaction_id,
                    date'2019-06-20' as transaction_date,
                    200 as amount),

                struct('xxx', 2, date'2019-07-30', 1000),
                struct('xxx', 3, date'2019-04-10', 500),
                struct('xxx', 4, date'2019-05-15', 2000)
            ]
        )
),

cashbacks as (
    select
        *
    from
        unnest(
            array[
                struct(
                    'xxx' as pos_id,
                    date'2019-01-01' as start_date,
                    date'2019-04-30' as end_date,
                    0.1 as cashback),

                struct('xxx', date'2019-07-01', date'2019-09-30', 0.2)
            ]
        )
)


select
    t.*,
    c.* except(pos_id)
from
    transactions as t
    left join cashbacks as c
        on  t.pos_id = c.pos_id
            and t.transaction_date between  c.start_date
                                            and c.end_date
order by
    1, 3 desc
