您好我正在尝试复制我使用SQL的sumproduct,但我正在努力。我有一些资产类型的值和另一个有权重的表。
R1 TBL1
R2 Sim Type A Type B Type C
R3 1 1.836 1.794 1.153
R4 2 1.629 1.128 1.928
R5 3 1.616 1.956 1.411
R6 4 1.350 1.590 1.958
R7
R8
R9 TBL2
R10 Asset ID Type A Type B Type C
R11 BA Der 12% 2% 5%
R12 BSL ENH 0% 20% 1%
R13 BSL Der 42% 6% 7%
在Excel中,我使用以下公式来创建输出:
Output (formulas)
Sim BA Der BSL ENH
1 =SUMPRODUCT(B3:D3,$B$11:$D$11) =SUMPRODUCT(B3:D3,$B$12:$D$12)
2 =SUMPRODUCT(B4:D4,$B$11:$D$11) =SUMPRODUCT(B4:D4,$B$12:$D$12)
3 =SUMPRODUCT(B5:D5,$B$11:$D$11) =SUMPRODUCT(B5:D5,$B$12:$D$12)
4 =SUMPRODUCT(B6:D6,$B$11:$D$11) =SUMPRODUCT(B6:D6,$B$12:$D$12)
Output (values)
Sim BA Der BSL ENH
1 0.313824843 0.37037487
2 0.314473553 0.244925331
3 0.303555238 0.405301715
4 0.291739471 0.33764572
所以基本上我使用SUMPRODUCT将不同的加权类别应用于模拟
我希望在Access或SQL Server中做任何建议?

这应该是sumproduct等价物的基本实现:
SELECT id, SUM(type * weight) AS sum_product FROM tbl_TableName GROUP BY id
尝试根据您的情况调整此项。

我已经设法在SQL Server中创建了一个可行的解决方案,尽管它可能会通过一些优化来减少SQL。
创建脚本:
CREATE TABLE Tbl1 ([Sim] int, [TypeA] float, [TypeB] float, [TypeC] float)
INSERT INTO Tbl1 ([Sim], [TypeA], [TypeB], [TypeC])
VALUES (1, 1.836, 1.794, 1.153),
(2, 1.629, 1.128, 1.928),
(3, 1.616, 1.956, 1.411),
(4, 1.350, 1.590, 1.958)
CREATE TABLE Tbl2 ([Asset_ID] varchar(7), [TypeA] int, [TypeB] int, [TypeC] int)
INSERT INTO Tbl2 ([Asset_ID], [TypeA], [TypeB], [TypeC])
VALUES ('BA_Der', 12, 2, 5),
('BSL_ENH', 0, 20, 1),
('BSL_Der', 42, 6, 7)
Sum Product Equivalent
select Sim,
cast(
(select t1.TypeA*(t2.TypeA*0.01)
from tbl2 t2
where t2.Asset_ID = 'BA_Der')
+ (select t1.TypeB*(t2.TypeB*0.01)
from tbl2 t2 where t2.Asset_ID = 'BA_Der')
+ (select t1.TypeC*(t2.TypeC*0.01)
from tbl2 t2
where t2.Asset_ID = 'BA_Der') as decimal(18,10)) [BA Der],
cast(
(select t1.TypeA*(t2.TypeA*0.01)
from tbl2 t2
where t2.Asset_ID = 'BSL_ENH')
+ (select t1.TypeB*(t2.TypeB*0.01)
from tbl2 t2
where t2.Asset_ID = 'BSL_ENH')
+ (select t1.TypeC*(t2.TypeC*0.01)
from tbl2 t2
where t2.Asset_ID = 'BSL_ENH') as decimal(18,10)) [BSL ENH]
from Tbl1 t1
这实际上将计算细分为SUM
Values * Percentages
(TypeA_Value * TypeA_Percentage)
+ (TypeB_Value * TypeB_Percentage)
+ (TypeC_Value * TypeC_Percentage) = SUMPRODUCT
| SIM | BA DER | BSL ENH |
|-----|---------|---------|
| 1 | 0.31385 | 0.37033 |
| 2 | 0.31444 | 0.24488 |
| 3 | 0.30359 | 0.40531 |
| 4 | 0.2917 | 0.33758 |

Output (formulas)
Sim BA Der BSL ENH
1 =SUMPRODUCT(B3:D3,$B$11:$D$11) =SUMPRODUCT(C3:E3,$B$12:$D$12)
. .... ...
此输出与您的输出不同,但我假设您的总和产品公式中存在错误。你在哪里:
Output (formulas)
Sim BA Der BSL ENH
1 =SUMPRODUCT(B3:D3,$B$11:$D$11) =SUMPRODUCT(B3:D3,$B$12:$D$12)
. .... ...
我假设公式应该是:
C3:E3
因此,在第二列中将B3:D3
替换为{{1}},因为它引用了一个空单元格。
答案 2 :(得分:0)
尝试:
SELECT Sim, ((A.TypeA * B.TypeA) + (A.TypeB * B.TypeB) + (A.TypeC * B.TypeC)) 'BA Der',
((A.TypeA * C.TypeA) + (A.TypeB * C.TypeB) + (A.TypeC * C.TypeC)) 'BSL ENH'
FROM tbl1 A, tbl2 B, tbl2 C
WHERE B.AssetID = 'BA Der'
AND C.AssetID = 'BSL ENH'
