Sql 需要正确显示联合数据

我正在尝试在该表和另一个表中显示患者选择的数据，但所有患者数据都显示为

IsKeyAttrIsChecked

标志

问题：-

 select 
    a.KeyAttribute,
    a.PatKeyAttId,
    b.IsKeyAttrIsChecked,
    b.PatientUserId
from PatientKeyAttributeMaster a 
    Left join PatientKeyAttributeMap b 
        on (a.PatKeyAttId = b.PatKeyAttributeId)
UNION 
select 
    keyAttribute,
    PatKeyAttId,
    IsKeyAttrIsChecked,
    PatientUserId
from 
    (
        select 
            a.KeyAttribute,
            a.PatKeyAttId,
            b.IsKeyAttrIsChecked,
            b.PatientUserId
        from PatientKeyAttributeMaster a 
            inner join PatientKeyAttributeMap b 
                on (a.PatKeyAttId = b.PatKeyAttributeId)
        where b.PatientUserId = 176845 or b.IsKeyAttrIsChecked=1
    ) as a 
group by keyAttribute,PatKeyAttId,IsKeyAttrIsChecked,PatientUserId

输出：-

   KeyAttribute             |   PatKeyAttId |IsKeyAttrIsChecked|PatientUserId

预期产出：-

这是上面的帖子

恐怕我不知道你希望我们怎么回答这个问题。个别语句返回什么？他们给了你正确的行吗？我们这里没有任何原始数据。例如，为什么

工作愤怒

在预期输出中有

NULL

值？为什么值

177847

和

177849

不适用，因为它们显然是由数据集返回的。这是一个很好的开始：另外，请对齐您的列，您的数据很难像这样读取。而且，我最讨厌的一点是：。这在您的查询中尤其糟糕，其中

a

可以是第一个子查询或第二个子查询中的

PatientKeyAttributeMaster

，或者

a

可以是第一个子查询中返回的整个数据集<代码>b同样糟糕。我真的建议研究如何使用合适的别名。@Larnu不，先生，这个数据就是dumy数据，举个例子，所有这些值都在一列中。
