having子句中的sql sum列不是按季度值求和

我想对购买价值大于0且的客户的购买金额进行汇总，我想您需要：

select customerID, purchase_prd, count(*), sum(purchase_value)
from table a
where purchase_prd between 201700 and 201712 /*data is quarterly, so 201700, 201703, 201706,201709, 201712*/
group by customerid, purchase_prd
having sum(purchase_value) > 0 and sum(purchase_value) <= 500

---

样本数据和期望的输出会很有帮助。同时标记数据库名称我的结果是：请澄清问题。你真的很难实现你想要实现的目标。同时标记您正在使用的数据库。样本数据和所需结果将有所帮助。可能希望将purchase_prd保留在SELECT中，即使您已将其正确地放置在group by…：上面的查询不起作用，没有给我总购买值>0的customerID计数-如果在上面的查询中添加countdistinct customer\u id会怎么样？？

purchase_prd            customer ID         purchase_value
201700                          714              776
201703                           714              120
201706                           714              50
201709                            714             20
201712                           714              100

select customerID, purchase_prd, count(*), sum(purchase_value)
from table a
where purchase_prd between 201700 and 201712 /*data is quarterly, so 201700, 201703, 201706,201709, 201712*/
group by customerid, purchase_prd
having sum(purchase_value) > 0 and sum(purchase_value) <= 500
