【问题描述】：
我有两个这样的表，sales.id_Location = location.id_location（这不是真实数据，只是数据虚拟）在销售表上，id_order 是交易历史，createdAt 是交易发生的日期，sale 是金额交易量（kg），id_Location是与位置表中id_location相连的发货位置，createdby是买家。
CREATE TABLE sales
(
id_order VARCHAR(50) NOT NULL,
createdAt datetime NOT NULL,
sale DECIMAL(14,2) NOT NULL,
id_location varchar(50) NOT NULL,
createdby varchar(50) NOT NULL,
PRIMARY KEY(id_order,createdAt)
);
INSERT INTO sales (id_order, createdAt, sale, id_location, createdby)
VALUES(1,'2016-02-02',100, 1, 123),
(2,'2017-03-02',150, 2, 233),
(3,'2018-02-02',200, 3, 234),
(4,'2016-03-03',150, 1, 123),
(5,'2017-03-04',100, 2, 2334),
(6,'2018-03-05',200,3, 234),
(7,'2016-03-10',200, 1, 233),
(8,'2017-02-01',150, 2, 124),
(9,'2018-02-04',250, 3, 233),
(10,'2018-02-05',300, 2, 124);
CREATE TABLE location
(
id_location varchar(50) NOT NULL,
location_city varchar(50) NOT NULL
);
INSERT INTO location(id_location, location_city)
VALUES (1, 'Jakarta'),
(2, 'Depok'),
(3, 'Bekasi');
select * from sales;
select * from location;

在这种情况下，我使用了 mysql 5.7 版，我想在这个条件下找出每个位置的销售统计数据
销售额在 '2016-02-01' 到 '2018-03-10' 之间
买家（
createdby列）在 '2018-03-10' 之前进行交易，并且至少在 '2016-02-01' - '2018- 之间进行交易再次 03-10'，
因此，如果买家只是进行了一次交易，或者进行了多次交易，但在 '2016-02-01' 到 '2018-03-10' 之间根本没有交易，则不计入买家并且不包括在内
基于该条件和数据虚拟，预期结果如下：
+----------+----------+---------+----------------+--------------------+
| Location | sale(kg) | sale(%) | count id_order | count id_order (%) |
+----------+----------+---------+----------------+--------------------+
| Jakarta | 450 | 26,48 | 3 | 33,33 |
| Depok | 600 | 35,30 | 3 | 33,33 |
| Bekasi | 650 | 38,22 | 3 | 33,33 |
| TOtal | 1700 | 100 | 9 | 100 |
+----------+----------+---------+----------------+--------------------+
这是我的 SQL 语句：
SELECT
IFNULL(location.location_city, 'Total') AS `Location`,
SUM(sale) AS `sale(kg)`,
SUM(sale) / (SELECT SUM(sale) FROM sales) * 100 AS `sale (%)`,
COUNT(id_order) AS `count(id_order)`,
COUNT(id_order) / (SELECT COUNT(id_order) FROM sales) * 100 AS `count(id_order) (%)`
FROM sales, location
where sales.id_location = location.id_location
and createdAt <= '2018-03-04'
and EXISTS (select 1 from sales s2, location l2 where
sales.id_location = s2.id_location
and sales.id_location = l2.id_location and
createdAt >= '2016-02-01'
and createdAt <= '2018-03-04')
GROUP BY location WITH ROLLUP
having count(createdby) > 1;

请注意，我们停止以这种方式编写查询 ca。 1992.来吧。加入我们。

注意！谢谢楼主

不清楚...为什么要计算
createdby = 234的销售额？他不符合条件 (2) - 他在 '2018-03-04' 或之前只有一次销售...... -
对不起，先生，请检查我的编辑，非常感谢@Akina

您的版本没有改变我所说的问题。期望的结果与条件不匹配。
