Question

我正在寻找一个查询，该查询将从给定日期开始累计重新激活收入。目前我有以下查询;

    SELECT advertisable, EXTRACT(YEAR from day), EXTRACT(MONTH from day), ROUND(SUM(cost)/1e6)  FROM adcube dac
WHERE advertisable_eid IN 

(SELECT advertisable FROM adcube dac 
GROUP BY advertisable HAVING SUM(cost)/1e6 > 100)

GROUP BY advertisable, EXTRACT(YEAR from day), EXTRACT(MONTH from day)
ORDER BY advertisable, EXTRACT(YEAR from day), EXTRACT(MONTH from day)

从此我然后导出到excel并检查帐户，他们已停止花费4个月然后重新激活。然后，我跟踪新的重新启动月份的新收入。

是否可以在不需要Excel的情况下获取SQL查询？

假设数据中实际存在四个月，您可以使用窗口函数执行此操作。您可以通过获取两个row_numbers()之间的差异来连续找到 N 事物。这是一个想法：

with t as (
      SELECT advertisable, EXTRACT(YEAR from day) as yy, EXTRACT(MONTH from day) as mon, 
             ROUND(SUM(cost)/1e6) as val
      FROM adcube dac
      WHERE advertisable_eid IN (SELECT advertisable
                                 FROM adcube dac 
                                 GROUP BY advertisable
                                 HAVING SUM(cost)/1e6 > 100
                                )
      GROUP BY advertisable, EXTRACT(YEAR from day), EXTRACT(MONTH from day)
     )
select advertisable, min(yy * 10000 + mon) as yyyymm
from (select t.*,
             (row_number() over (partition by advertisable order by yy, mon) -
              row_number() over (partition by advertisable, val order by yy, mon)
             ) as grp
      from t
     )
group by advertisable, grp, val
having count(*) >= 4 and val = 0;
