我正在尝试为客户选择归档为“重复”或“归档”的不同产品。
select a.customer_id,
a.type -- reccuring/on file,
b.name as product_name,
from table.a as a
join table.c as c on c.id = a.c_id
join table.b as b on b.id = c.b_id
where a.current_state <> 'canceled'
order by 1
我的输出如下:
id/type/product_name
<br> 111 on_file someProduct
<br> 111 recurring someOtherProduct
<br> 112 on_file someProduct
<br> 112 recurring someProduct
最终目标是仅选择具有相同产品名称且类型均为on_file和重复出现的客户。我尝试对它们进行排名,但是即使它们具有相同的名称,也具有不同的产品ID
答案 0 :(得分:1)
我想您需要以下查询
Select id, product_name,
count(distinct type) from
Table where type in
('on_file', 'recurring') group by id,
Product_name
having
count(distinct type)=2
