Question

我有以下两个表格，我想加入一个全面的数字营销报告，而不会在指标方面产生重复。我们的想法是获取竞争对手的广告，并将其与我现有的营销数据结合起来，如下所示;

 Campaign|Impressions | Clicks | Conversions | CPC |Key                             
---------+------------+--------+-------------+-----+----
  USA-SIM|53432       |  5001  |            5| 2$  |Hgdy24
  DE-SIM |5389        |  4672  |            3| 4$  |dhfg12

竞争对手的数据如下;

  dhfg12 |Check it out|
  dhfg12 |World known |

使用传统的连接查询会产生以下不可用的结果

 Campaign|Impressions | Clicks | Conversions | CPC |Key   |Ad Copie                    
---------+------------+--------+-------------+-----+------+---------
  USA-SIM|53432       |  5001  |            5| 2$  |Hgdy24|Click here!
  USA-SIM|53432       |  5001  |            5| 2$  |Hgdy24|Free Trial!
  USA-SIM|53432       |  5001  |            5| 2$  |Hgdy24|Sign Up now 
  DE-SIM |5389        |  4672  |            3| 4$  |dhfg12|Check it out
  DE-SIM |5389        |  4672  |            3| 4$  |dhfg12|World known
  DE-SIM |5389        |  4672  |            3| 4$  |dhfg12|Sign up

这是所需的输出

 Campaign|Impressions | Clicks | Conversions | CPC |Key   |Ad Copie                    
---------+------------+--------+-------------+-----+------+---------
  USA-SIM|53432       |  5001  |            5| 2$  |Hgdy24|Click here!
  USA-SIM|            |        |             |     |Hgdy24|Free Trial!

  DE-SIM |5389        |  4672  |            3| 4$  |dhfg12|Check it out
  DE-SIM |            |        |             |     |dhfg12|World known
  DE-SIM |            |        |             |     |dhfg12|Sign up

或作为替代方案也可以

---------+------------+--------+-------------+-----+------+---------
  USA-SIM|53432       |  5001  |            5| 2$  |Hgdy24|

我还没有找到一个不会产生额外指标的工作。

您可以使用窗口函数lag()来检查前一行中key的内容，并显示指标或将其归零。

select campaing,
       case when prev_key is null or prev_key != key then impressions end as impressions,
       case when prev_key is null or prev_key != key then clicks end as clicks,
       case when prev_key is null or prev_key != key then conversions end as conversions,
       case when prev_key is null or prev_key != key then cpc end as cpc,
       key, ad_copie
  from (
    select campaing, lag(key) over () AS prev_key, impressions, clicks, conversions, cpc, key, ad_copie
    from ad1
    join comp1 using(key)
    order by campaing desc, key
  ) sub;

结果：

 campaing | impressions | clicks | conversions | cpc |  key   |   ad_copie

编辑：您可能需要在NULL指标之前修改您比较的列，并且可能需要修改您将订购数据的列。如果密钥对于竞选是唯一的，那么我认为这就足够了。

连接数据而不从第一个表创建重复的度量标准行，（第二个表包含更多行但不包含度量标准）
