Необходимо правильно отобразить данные объединения

Question

Я пытаюсь сопоставить данные, выбранные пациентом в этой таблице, и все другие таблицы показывают это, но есть все данные пациента, отображаемые с IsKeyAttrIsChecked флагом

Запрос: -

 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

вывод: -

   KeyAttribute             |   PatKeyAttId |IsKeyAttrIsChecked|PatientUserId
Anxiety                         4041            NULL            NULL
Drop in work performance        4039            1               177849
Drowsiness                      4032            NULL            NULL
Excess weight gain              4036            NULL            NULL
Irritability                    4040            1               171834
 Anger at work                  4040            1               177847
Anger at work                   4040            1               177849
Persistent backache             4034            1               171834
Persistent cough                4035            1               176845

Ожидаемый вывод: -

KeyAttribute            |   PatKeyAttId |IsKeyAttrIsChecked|PatientUserId
Anxiety                         4041            NULL            NULL
