我想添加最近 30 天的销售和 30 到 90 天的销售，并增加权重 (1.5) 到最近 30 天的销售

Question

我想将最近 30 天的销售和 30 到 90 天的销售添加到最近 30 天的销售中，并增加权重 (1.5)。

SELECT userid, SUM(premiumdetails_netpremium)
from policydetail,
     (SELECT userid AS partner_id, SUM(premiumdetails_netpremium) AS last30sale
      FROM policydetail AS pd
      WHERE DATE(sales_date) BETWEEN current_date - interval '30' day AND current_date
      group by userid
     ) AS A 
WHERE DATE(sales_date) BETWEEN current_date - interval '90' day AND current_date
group by userid

Answer 1

我想你想要条件聚合：

SELECT userid,
       SUM(CASE WHEN sales_date >= current_date - interval '30 day THEN 1.5 * premiumdetails_netpremium
                ELSE premiumdetails_netpremium
           END) as weighted_sum
FROM policydetail
WHERE sales_date >= current_date - interval '90' day 
GROUP BY userid ;

请注意，这假设 sales_date 不在未来。
