Question

需要创建一个查找一组记录的查询，如下所示：

ID  |  Address    |  Unit | Status

1   |555 Smith Rd | Apt A | Success
2   |555 Smith Rd | Apt B | Success
3   |555 Smith Rd | Apt C | Success
4   |555 Smith Rd | Apt D | Failure

我需要选择Address字段匹配的记录以及状态字段不匹配的位置。理想情况下，我想显示上面例子中的记录组。

Answer 1

您可以使用分析函数：

select id, address, unit, status
from (select t.*, min(status) over (partition by address) as mins,
             max(status) over (partition by address) as maxs
      from table t
     ) t
where mins <> maxs
order by address;

SQL Query查找与辅助匹配属性不匹配的属性
