我们有Microsoft SQL Server10.50.6529。每当我运行此查询时，我会得到不同的结果：
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);
我已将两个内部查询替换为具有相同效果的临时表。 数据库是静态的，这意味着，在查询运行时，没有创建任何其他记录。
有没有人有想法，如何解决这种奇怪的行为？
我们得到：首先尝试：

使用row_number窗口函数时，我遇到过类似的问题。最有可能的是，你的订购并没有打破平局。如果Incident_Number中的重复项没有打破平局，则会导致行的排名不同：
PARTITION BY A.Incident_Number ORDER BY A.Incident_Number
尝试在ID之后添加一些Incident_Number的订单：
PARTITION BY A.Incident_Number ORDER BY A.Incident_Number, A.ID
可以改写为：
PARTITION BY A.Incident_Number ORDER BY A.ID
