时间Thu Sep 7 21:46:24 2017
select sum(t1.CU_order_amount) as 金额,
t3.CU_name as 地区
from CU_order t1
inner join CU_cust_info t2 on t1.CU_cust_id = t2.CU_cust_id
inner join CU_city t3 on t2.CU_city_id = t3.CU_city_id
where t1.BillDate between '20160101' and '20171231'
group by t3.CU_name
※ 引述《nd5287 (Mike)》之铭言：
: 资料库名称：
: 资料库版本：sql 2014
: 内容/问题描述：
: 我下了 以下的语法查询出的结果如下
: select DISTINCT B.CU_order_amount "金额",D.CU_name as "地区",
: B.BillDate as "日期" from CU_order B
: join CU_cust_info C on B.CU_cust_id=C.CU_cust_id
: join CU_city D on C.CU_city_id = D.CU_Id
: where B.CU_cust_id in
: (select CU_cust_id from CU_cust_info C where CU_city_id in (select CU_city_id
: from CU_city ))
: and B.BillDate Between '20160101' and '20171231'
: order by B.CU_order_amount desc
: 金额 地区 日期
: --------------------------------------------------
: 700 台北市 20170105
: 300 新北市 20160501
: 200 台北市 20170509
: 200 新北市 20170901
: 500 台北市 20160405
: 请问一下如果我要将这段查询的结果 再针对地区分组 且把金额加总该怎麽做?
: 因为我已经跨表取值了，不知道怎麽针对已经查询到的结果再作group by 和 sum。
: 再麻烦大家帮我看一下，谢谢。
