在额外聚合上使用 Sum 和 Make Total

Question

我想创建一个索引视图。

我有这个查询：

SELECT srvmn.BBC_ID AS Inventory,
       srvInv.ObjectID,
       srv.State,
       SUM(  IIF(srvInv.Direction = srvInv.ReverseBroken, 1, 0)) AS Broken,
       SUM(IIF(srvInv.Direction = 0, 1, -1)) AS Sum,
       COUNT_BIG(*) AS CountLines
FROM table1 srvmn
    JOIN table2 srv
        ON srv.ServiceManID = srvmn.ID
    JOIN table3 srvInv
        ON srv.ID = srvInv.ServiceID
WHERE srv.State > 321
      AND srv.State <> 123
GROUP BY srvInv.ObjectID,
         srv.State,
         srvInv.Direction,
         srvInv.ReverseBroken,
         srvmn.BBC_ID
         ORDER BY srvInv.ObjectID

所以，Sum 无法正常工作，我也用这种方法修复它：

SELECT A.Inventory,
   A.ObjectID,
   A.State,
   A.Broken,
   SUM(A.Sum) AS Sum
FROM
(
    SELECT srvmn.BBC_ID AS Inventory,
           srvInv.ObjectID,
           srv.State,
           IIF(srvInv.Direction = srvInv.ReverseBroken, 1, 0) AS Broken,
           SUM(IIF(srvInv.Direction = 0, 1, -1)) AS Sum,
           COUNT_BIG(*) AS CountLines
    FROM table1 srvmn
        JOIN table2 srv
            ON srv.ServiceManID = srvmn.ID
        JOIN table3 srvInv
            ON srv.ID = srvInv.ServiceID
    WHERE srv.State > 321
          AND srv.State <> 123 
    GROUP BY srvInv.ObjectID,
             srv.State,
             srvInv.Direction,
             srvInv.ReverseBroken,
             srvmn.BBC_ID
) AS A
GROUP BY A.Inventory,
         A.ObjectID,
         A.State,
         A.Broken;

结果正常，但索引视图中不允许派生表。
我尝试在 Sum 中使用 "Over Partition"，但结果不正确。

我该如何解决这个问题？

正确结果：

Inventory   ObjectID    State   Broken  Sum
------------------------------------------------
NULL        2           500     0       -1
NULL        3           320     1       1
NULL        3           500     0       2
NULL        3           600     0       1

1162        28          600     0       3

不正常结果：

Answer 1

您不应在 "Group By"

中使用字段 "srvInv.Direction"

Answer 2

请试一试:

SELECT 
        srvmn.BBC_ID AS Inventory,
        srvInv.ObjectID,
        srv.State,
        SUM(IIF(srvInv.Direction = srvInv.ReverseBroken, 1, 0)) AS Broken,
        SUM(IIF(srvInv.Direction = 0, 1, -1)) AS Sum
    FROM table1 srvmn
    JOIN table2 srv     ON srv.ServiceManID = srvmn.ID
    JOIN table3 srvInv  ON srv.ID = srvInv.ServiceID
        WHERE srv.State > 321 AND srv.State <> 123
            GROUP BY 
                srvInv.ObjectID,
                srv.State,
                srvInv.ReverseBroken,
                srvmn.BBC_ID

在额外聚合上使用 Sum 和 Make Total
