如何使用SQL将所有下线汇总到他们的直线上线。

所有员工销售均为主管销售。
所有主管销售均为经理的销售。
所有经理销售均为负责人。

当前数据：

ID   Name     Role            Level      Reportingto     Sales
---------------------------------------------------------------
1    Joe      Head              1          NULL           0
2    Smith    Manager           2           1             0
3    Mike     Supervisor        3           2             0
4    Mitch    Staff             4           3             10
5    Jen      Staff             4           3             20
6    Ian      Manager           2           1             0
7    Jess     Supervisor        3           6             0
8    Rocky    Staff             4           7             5
9    Jessica  Supervisor        3           6             0
10   Rolly    Staff             4           9             3

理想输出

ID   Name     Role            Level      Reportingto     Sales
---------------------------------------------------------------
1    Joe      Head              1          NULL           38
2    Smith    Manager           2           1             30
3    Mike     Supervisor        3           2             30
4    Mitch    Staff             4           3             10
5    Jen      Staff             4           3             20
6    Ian      Manager           2           1             8
7    Jess     Supervisor        3           6             5
8    Rocky    Staff             4           7             5
9    Jessica  Supervisor        3           6             3
10   Rolly    Staff             4           9             3

我正在使用SQL Server 2016

Answer 1

您可以使用outer apply。

select t1.id,t1.name,t1.role,t1.level,t1.reportingto,coalesce(t2.sales,t1.sales) as val
from t t1
outer apply (select sum(sales) as sales
             from t t2 
             where t1.id<=t2.id and t1.level<t2.level) t2

Answer 2

可能有一种更简单的方法可以做到这一点，但在我看来，你需要从“工作人员”开始。并递归：

;with cte as (SELECT [ID], [Name], [Role], [Level], [Reportingto], [Sales], Sales as Sum_Sales
              FROM #Table1 
              WHERE [Role] = 'Staff'
              UNION ALL
              SELECT a.[ID], a.[Name], a.[Role], a.[Level], a.[Reportingto], a.[Sales], a.Sales + b.Sum_Sales AS Sum_Sales
              FROM #Table1 a
              JOIN cte b
                 ON b.Reportingto = a.ID
              )
SELECT [ID], [Name], [Role], [Level], [Reportingto],SUM(Sum_Sales) as Sales
FROM cte
GROUP BY [ID], [Name], [Role], [Level], [Reportingto]

Answer 3

假设该表为KTemp，我创建了一个新列。希望这可以帮助。

 SELECT *,
           CASE
               WHEN LEVEL=1 THEN
                      (SELECT sum(Sales)
                       FROM KTemp x
                       WHERE x.Level IN (1,
                                         2,
                                         3,
                                         4) )
               WHEN LEVEL=2 THEN
                      (SELECT sum(Sales)
                       FROM KTemp x
                       WHERE x.Level IN (2,
                                         3,
                                         4) )
               WHEN LEVEL=3 THEN
                      (SELECT sum(Sales)
                       FROM KTemp x
                       WHERE x.Level IN (3,
                                         4) )
               WHEN LEVEL=4 THEN
                      (SELECT sum(Sales)
                       FROM KTemp x
                       WHERE x.Level IN (4) )
           END AS [Up-line Sales]
    FROM KTemp
