sql查询中的having子句返回无效

Question

我正在尝试检索符合以下条件的所有ID：

1. 住在特定的街道上
2. 有两个电话号码
3. 已下订单
4. 是女性

select id from Customer 
join Address on Address.customer_id = Customer.id
join Orders on Orders.customer_id = Customer.id
join Gender on Gender.customer_id = Customer.id
join Telephone on Telephone.customer_id = Customer.id
where Address.street_name ='MainStreet' 
and Orders.customer_id is not null
and Gender.gender ='Female'
group by Telephone.customer_id
having count(Telephone.customer_id) = 2

运行此命令时，我收到“列或表达式无效”的提示当我删除并删除该组时，它可以正常工作。

有人可以帮我吗？

试试这个

select id from Customer 
join Address on Address.customer_id = Customer.id
join Orders on Orders.customer_id = Customer.id
join Gender on Gender.customer_id = Customer.id
join (
select customer_id from Telephone
group by customer_id
having count(customer_id) = 2
) AS Telephone on Telephone.customer_id = Customer.id
where Address.street_name ='MainStreet' 
and Orders.customer_id is not null
and Gender.gender ='Female'
