获取每天的产品销售平均计算具有积极的销售

Question

我有以下几列

SELECT DATE, WEEK, BRANCH, PROD, TARGETREACH 
FROM TARGETSALE 
WHERE BRANCH = 1 
AND WEEK BETWEEN 52 AND 53; 

DATE  WEEK BRANCH PROD TARGETREACH 
------------------------------------------------------------------- 
01/09/2014 52  1  1  50 
02/09/2014 52  1  1  -10 
03/09/2014 52  1  1  50 
04/09/2014 52  1  1  50 
05/09/2014 52  1  1  40 
06/09/2014 52  1  1  -10 
07/09/2014 53  1  1  -5 
08/09/2014 53  1  1   0 
09/09/2014 53  1  1  10 
10/09/2014 53  1  1  20 
11/09/2014 53  1  1  30 
12/09/2014 53  1  1  40 
13/09/2014 53  1  1   0 
01/09/2014 52  1  2  20 
02/09/2014 52  1  2   0 
03/09/2014 52  1  2   0 
04/09/2014 52  1  2  10 
05/09/2014 52  1  2  20 
06/09/2014 52  1  2  10 
07/09/2014 53  1  2  -10 
08/09/2014 53  1  2  10 
09/09/2014 53  1  2  -10 
10/09/2014 53  1  2  20 
11/09/2014 53  1  2  20 
12/09/2014 53  1  2  40 
13/09/2014 53  1  2   0 
01/09/2014 52  1  3  30 
02/09/2014 52  1  3  30 
03/09/2014 52  1  3   5 
04/09/2014 52  1  3   0 
05/09/2014 52  1  3  10 
06/09/2014 52  1  3  -10 
07/09/2014 53  1  3  -10 
08/09/2014 53  1  3  -10 
09/09/2014 53  1  3  20 
10/09/2014 53  1  3  10 
11/09/2014 53  1  3  40 
12/09/2014 53  1  3  10 
13/09/2014 53  1  3  10 

“targetsales”这个表TARGETSALE天数显示销售了多少超过目标，其中负数表示销售额低于目标多少。我如何做到以下几点： 1.我需要获得每天所有产品的平均值。事情是这样的：

DATE  BRANCH AVERAGE_SALES_OF_ALL_PRODUCT 
    01/09/2014 1  33.33 
    02/09/2014 1  -1.67 
    ...and so on 

然后我需要另一个查询，显示如何在这两周内的许多日子，有积极的平均销售。事情是这样的：

BRANCH 2WEEKS_SINCE DAYS_WITH_POSITIVE_AVERAGE_SALES 
1  53    9 

以上只是举个例子不是一个真实的结果。 对不起，希望这不是太混乱。非常感谢。

Answer 1

在Oracle中，date型仍然可能有一个时间分量。如果你不知道这是不是在那里，然后用trunc()将其删除：

select trunc(date), branch, avg(targetreach) 
from targetsale 
group by truncdate, branch 
order by 1, 2; 

对于第二个查询，您要使用case：

select branch, count(distinct case when targetreach > 0 then date end) as DaysWithPositiveSales 
from targetsales 
group by branch; 

如果你知道有每一个行每个分支的日期 - 和日期的时间部分是空的 - 那么distinct是没有必要的。

Answer 2

1）

SELECT TRUNC(DATE, 'DD'), BRANCH, SUM(TARGETREACH) 
FROM TARGETSALE WHERE BRANCH = 1 AND WEEK BETWEEN 52 AND 53 
GROUP BY TRUNC(DATE, 'DD'), BRANCH; 

2）

SELECT BRANCH, SUM(DECODE(ABS(TARGETREACH), 1, 1, 0) 
FROM TARGETSALE WHERE BRANCH = 1 AND WEEK BETWEEN 52 AND 53 
GROUP BY BRANCH;
