求和一列,减去第二列

Question

我想显示两列的减法.从第一列我需要得到所有值的总和并减去第二列中的每个值.

这是表结构:

id | name | col1  | col2 | date
------------------------------------
432| xxx  | 0     | 15   |2015-11-17
432| yyy  | 10    | 30   |2015-11-19 
432| zzz  | 60    | 40   |2015-11-20  

433| aaa  | 0     | 60   |2015-11-17
433| bbb  | 80    | 20   |2015-11-19 
433| ccc  | 60    | 10   |2015-11-20  

公式应该去:

sum(col1) = 70  =>>>   WHERE ID = 432  

70 - col2            col3
-------------------------
=> 70 - 15         =  55
=> 70 - (30 + 15)  =  25 
=> 70 - (40 + 45)  = -15
---------------------------

sum(col1) = 140  ===>>    WHERE ID = 433  

 140 -   col2         col3
-------------------------
=> 140 -  60        =  80
=> 140 - (60 + 20)  =  60 
=> 140 - (10 + 80)  =  50

结果是col3,输出应该像

id | name | col1  | col2 | col3 |    date
-------------------------------------------
432| xxx  | 0     | 15   |  55  |  2015-11-17
432| yyy  | 10    | 30   |  25  |  2015-11-19 
432| zzz  | 60    | 40   | -15  |  2015-11-20  

433| aaa  | 0     | 60   |  80  |  2015-11-17
433| bbb  | 80    | 20   |  60  |  2015-11-19 
433| ccc  | 60    | 10   |  50  |  2015-11-20

编辑:如果我需要的值取决于组作为432和433 id列.

Answer 1

架构信息

DECLARE @TEST TABLE
  (
     id INT,
     name VARCHAR(10),
     col1       INT,
     col2        int
  ) 

INSERT INTO @TEST VALUES 
(432,'xxx',0, 15 ),
(432,'yyy',10, 30 ),
(432,'zzz',60, 40 ),
(433,'aaa',0, 60 ),
(433,'bbb',80, 20 ),
(433,'ccc',60, 10 )

询问

    SELECT  T.id ,
        T.name ,
        T.col1 ,
        T.col2 ,
        SUM(T.col1) OVER( PARTITION BY T.id ORDER BY T.id ROWS BETWEEN UNBOUNDED PRECEDING AND UNBOUNDED FOLLOWING)
        - SUM(T.col2) OVER ( PARTITION BY T.id ORDER BY T.id ROWS BETWEEN UNBOUNDED PRECEDING AND CURRENT ROW ) AS col3
FROM    @TEST T;

结果

id | name | col1  | col2 | col3 |
---------------------------------
432  | xxx  | 0     | 15   |  55  |
432  | yyy  | 10    | 30   |  25  |
432  | zzz  | 60    | 40   | -15  |
433  | aaa  | 0     | 60   |  80  | 
433  | bbb  | 80    | 20   |  60  | 
433  | ccc  | 60    | 10   |  50  |
