Результат SQL-запроса отличается от каждого запуска на статическом DB

Question

У нас есть Microsoft SQL Server10.50.6529. Всякий раз, когда я запускаю этот запрос, я получаю разные результаты:

SELECT YEAR(A.EndZeit) AS Jahr 
    , MONTH(A.EndZeit) AS Monat 
    , CASE b.Priority 
     WHEN 3 
      THEN 'Low' 
     ELSE ' ' 
     END AS "Priority" 
    , count(*) AS Anzahl 
FROM VIEW_INC_CI B 
JOIN (
    SELECT Endzeit 
     , Incident_Number 
    FROM (
     SELECT ROW_NUMBER() OVER (
       PARTITION BY A.Incident_Number ORDER BY A.Incident_Number 
       ) AS rk 
      , A.Incident_Number 
      , A.EndZeit 
     FROM Calculation.IncidentAssignmentHistory A 
     JOIN SPG.GruppenGruppen G 
      ON A.AssignedGroupID = G.Support_Group_ID 
       AND G.GroupName = 'GRPName' 
     ) T 
    WHERE rk = 1 
    ) A 
    ON B.Incident_Number = A.Incident_Number 
WHERE B.Priority = 3 
    AND B.STATUS != 6 
    AND B.resolution_category NOT IN ('CategoryXY') 
GROUP BY MONTH(A.EndZeit) 
    , YEAR(A.EndZeit) 
    , B.Priority 
ORDER BY YEAR(A.EndZeit) 
    , MONTH(A.EndZeit); 

Я заменил оба внутренних запроса временными таблицами, имеющими тот же эффект. БД статична, что означает, что во время выполнения запроса не создаются дополнительные записи.

У кого-нибудь есть идея, как обойти это странное поведение?

Получаем: первая Попытка:

Jahr Monat Prio Anzahl 
2013 10 Low 772 
2013 11 Low 831 
2013 12 Low 777 
2014 1 Low 1087 
2014 2 Low 1033 
2014 3 Low 726 
2014 4 Low 763 
2014 5 Low 1799 
2014 6 Low 1964 
2014 7 Low 1912 
2014 8 Low 1776 
2014 9 Low 1682 
2014 10 Low 1715 
2014 11 Low 1623 
2014 12 Low 1507 
2015 1 Low 1755 
2015 2 Low 1994 

Второй Try:

2013 10 Low 775 
2013 11 Low 829 
2013 12 Low 778 
2014 1 Low 1087 
2014 2 Low 1031 
2014 3 Low 729 
2014 4 Low 758 
2014 5 Low 1797 
2014 6 Low 1973 
2014 7 Low 1912 
2014 8 Low 1779 
2014 9 Low 1678 
2014 10 Low 1706 
2014 11 Low 1620 
2014 12 Low 1516 
2015 1 Low 1748 
2015 2 Low 2002

Answer 1

Я видел подобные проблемы при использовании row_number окна функция. Скорее всего, ваш заказ не нарушает связь. В случае дублей в Incident_Number, не нарушая связь может привести к ранжированию строк по-разному:

PARTITION BY A.Incident_Number ORDER BY A.Incident_Number 

Попробуйте добавить заказ на некоторых ID после Incident_Number:

PARTITION BY A.Incident_Number ORDER BY A.Incident_Number, A.ID 

Это можно переписать в виде:

PARTITION BY A.Incident_Number ORDER BY A.ID
