我的sql看起来像:

create table ad(
  ad_id int,
  ad_name varchar(10)
);

insert into ad(ad_id, ad_name) values
  (1,'ad1'),
  (2,'ad2'),
  (3,'ad3');

 create table ad_insight(
   id int,
   ad_id int,
   date date, 
   clicks int
 );

insert into ad_insight(id, ad_id, date, clicks) values
    (1, 1, '2021-04-25', 1),
    (2, 1, '2021-04-24', 4),
    (3, 1, '2021-04-23', 2),
    (4, 2, '2021-04-25', 6),
    (5, 2, '2021-03-03', 7);

create table product(
    product_id int,
    product_name varchar(10)
);

insert into product(product_id, product_name) values
    (1,'prod1'),
    (2,'prod2'),
    (3,'prod3'),
    (4,'prod4'),
    (5,'prod5');

create table product_insight(
    id int,
    product_id int, 
    sale int, 
    date date
);
insert into product_insight(id, product_id, sale, date) values
    (1, 1, 12, '2021-04-25'),
    (2, 1, 11, '2021-04-24'),
    (3, 1, 13, '2021-04-23'),
    (4, 1, 14, '2021-04-22'),
    (5, 1, 17, '2021-04-21'),
    (6, 1, 15, '2021-04-20'),
    (7, 1, 13, '2021-04-19'),
    (8, 2, 19, '2021-04-25');

create table ads_products(
    ad_id int,
    product_id int
);
insert into ads_products (ad_id, product_id) values 
    (1, 1),
    (1, 2),
    (2, 3),
    (2, 4),
    (1, 3);

给你小提琴
对模式的快速解释:我有广告:
每个广告都有自己的见解,这些见解告诉我们某个广告何时活跃。
每个广告都有产品(很多- ads_products 表)。每个产品都有产品洞察,它告诉我们该产品在某一天产生了多少销售额。
现在我想得到下表,它总结了 ad_insight 表和产品销售汇总 product_insight2021-04-232021-04-25 包容的。

+----------+--------+--------------+--------------+
| ad_name  | clicks | product_sale |   products   |
+----------+--------+--------------+--------------+
| ad1      |      7 |           55 | prod1, prod2 |
| ad2      |      6 |            0 | prod3, prod4 |
| ad3      |      0 |           36 | prod1        |
+----------+--------+--------------+--------------+

我试过什么?

select ad_name, SUM(ad_insight.clicks) as clicks 
from ad 
left join ad_insight on ad.ad_id = ad_insight.ad_id 
where ad_insight.date >= '2021-04-23' and ad_insight.date <= '2021-04-25'
group by ad.ad_id;

但我不知道如何选择 product_sale 表格和产品之间用逗号分隔?
