Sql 按多个条目筛选查询结果

我有一个Access DB，表1包含以下信息：

ADDRESS_ID | CATEGORY_ID
1          | 12
2          | 41
2          | 66
3          | 41
4          | 41
4          | 66

每个地址_ID属于唯一分配的专用客户

我需要创建一个SQL查询，该查询只返回表中地址ID正好有一个专用条目的行，例如，如果我的筛选条件是Return CATEGORY_ID=41，则预期结果是：

ADDRESS_ID | CATEGORY_ID
3          | 41

或者，如果它是返回类别_ID=66，则结果为空表

如何在不按脚本执行后处理的情况下实现查询？

使用计数并具有：

我将使用不存在的：

此查询：

select address_id, max(category_id) category_id
from tablename
group by address_id
having min(category_id) = max(category_id)

返回：

仅表中地址_ID正好有一行的行 专用入口

现在，您可以对其应用任何过滤器，并获得所需的结果：

select t.* from (
    select address_id, max(category_id) category_id
    from tablename
    group by address_id
    having min(category_id) = max(category_id)
) t
where t.category_id = 41

我将使用group by，并拥有：

如果需要，您可以将41作为类别id添加到选择中，但您已经知道了这一点

如果表中没有重复对，您也可以将其表述为：

select address_id
from table1
group by address_id
having count(*) = 1 and
       min(category_id) = 41;

---

工作完美。谢谢

select t.* from (
    select address_id, max(category_id) category_id
    from tablename
    group by address_id
    having min(category_id) = max(category_id)
) t
where t.category_id = 41

select address_id
from table1
group by address_id
having min(category_id) = max(category_id) and
       min(category_id) = 41;

select address_id
from table1
group by address_id
having count(*) = 1 and
       min(category_id) = 41;
