如何找出为什么所有数据子集的总和比总和小1

Question

我有一些奖励数据。每个奖励或赠款都有一个赠款编号和金额以及实体的 ID。我按 ID 总结了奖励的计数和所有奖励的 $Amount。然后我根据范围检查返回一组总行或一个子集。

我怎样才能找出为什么所有子集的总和总是比总集小一？这是我的存储过程：

ALTER    Procedure [dbo].[FLAS2_List_Awards_V3_PrepAwards]
/* 
EXECUTE FLAS2_List_Awards_V3_PrepAwards 0
EXECUTE FLAS2_List_Awards_V3_PrepAwards 1
EXECUTE FLAS2_List_Awards_V3_PrepAwards 2
EXECUTE FLAS2_List_Awards_V3_PrepAwards 3
EXECUTE FLAS2_List_Awards_V3_PrepAwards 4
EXECUTE FLAS2_List_Awards_V3_PrepAwards 5
EXECUTE FLAS2_List_Awards_V3_PrepAwards 6
*/
-- populates #TempGrants according to range filter on TotalAmount
(
    @Range  int = 0
                    -- 0 = no filtering 
                    -- 1 = < $1 million
                    -- 2 = < $5 million
                    -- 3 = < $10 million
                    -- 4 = < $15 million
                    -- 5 = < $20 million
                    -- 6 = > $20 million
)
As
-- if calling sproc did not create this table, create here to allow unit testing
IF OBJECT_ID('tempdb..#TempGrants') IS NULL
BEGIN 
CREATE TABLE #TempGrants
(
    ID          nchar(6) NOT NULL
,   TotalAwards decimal (16, 0) NULL
,   TotalAmount decimal (16, 0) NULL
)
END
-- step 1. Summarize grants creating colums for HAVING filter
CREATE TABLE #TempGrantsUnfiltered
(
    ID          nchar(6) NOT NULL
,   TotalAwards decimal (16, 0) NULL
,   TotalAmount decimal (16, 0) NULL
)
insert into #TempGrantsUnfiltered
(
    ID          
,   TotalAwards 
,   TotalAmount 
)
select o.id
      ,COUNT( o.GrantNumber) as TotalAwards
      ,SUM( o.TotalObligatedAmount) as TotalAmount 
from dbo.FLAS2_Grants o
group BY O.ID
-- step 2. HAVING filter returns grant totals per range test
insert into #TempGrants
(
    ID          
,   TotalAwards 
,   TotalAmount 
)
select o.id
      ,TotalAwards
      ,TotalAmount 
from #TempGrantsUnfiltered o
WHERE
    CASE 
        When @Range = 0 Then 1  
        When @Range = 1 AND TotalAmount < 1000000 Then 1  
        When @Range = 2 AND TotalAmount BETWEEN  1000001  AND  5000000 Then 1  
        When @Range = 3 AND TotalAmount BETWEEN  5000001  AND 10000000 Then 1  
        When @Range = 4 AND TotalAmount BETWEEN 10000001  AND 15000000 Then 1  
        When @Range = 5 AND TotalAmount BETWEEN 15000001  AND 20000000 Then 1  
        When @Range = 6 AND TotalAmount > 20000000 Then 1  
        ELSE 0      -- where 0 = 1 rejects record
        END = 1     -- where 1 = 1 allows record
order by TotalAmount desc       

当我执行以下块时：

EXECUTE FLAS2_List_Awards_V3_PrepAwards 0
EXECUTE FLAS2_List_Awards_V3_PrepAwards 1
EXECUTE FLAS2_List_Awards_V3_PrepAwards 2
EXECUTE FLAS2_List_Awards_V3_PrepAwards 3
EXECUTE FLAS2_List_Awards_V3_PrepAwards 4
EXECUTE FLAS2_List_Awards_V3_PrepAwards 5
EXECUTE FLAS2_List_Awards_V3_PrepAwards 6

我在使用 SQL Management Studio 的消息窗口中得到以下结果：

(597 row(s) affected)

(597 row(s) affected)

(597 row(s) affected)

(65 row(s) affected)

(597 row(s) affected)

(341 row(s) affected)

(597 row(s) affected)

(89 row(s) affected)

(597 row(s) affected)

(39 row(s) affected)

(597 row(s) affected)

(23 row(s) affected)

(597 row(s) affected)

(39 row(s) affected)

我无法解释子集中缺少的行或总集中的额外行。有什么想法吗？

65 + 341 + 89 + 39 + 23 +39 = 596 < 597 

Answer 1

在 case 表达式中将 TotalAmount < 1000000 更改为 TotalAmount < 1000001。
