Sql server 多层次结构的小计和总计

我正在设置一个报告查询。我有多个层次的位置，我需要正确显示

我尝试过使用分组汇总，但无法获得所需的内容

这是我的数据样本

t左值

Branch  BranchName  Cluster Location    District    Value
0001      A           C1      Loc1         District1    1000
0002      B           C1      Loc1         District1    2000
0003      C           C2      Loc2         District1    3000
0004      D           C2      Loc2         District1    4000
0005      E           C3      Loc2         District1    5000

这就是我迄今为止所尝试的

SELECT  CASE WHEN GROUPING(a.cluster) = 1 THEN a.District
             WHEN GROUPING(a.branchname) = 1 THEN a.Cluster
             ELSE a.BranchName
        END ,
        SUM(a.Value) Value
FROM    ( SELECT    '0001' Branch ,
                    'A' BranchName ,
                    'C1' Cluster ,
                    'Loc1' Location ,
                    'District1' District ,
                    1000 Value
          UNION ALL
          SELECT    '0002' ,
                    'B' ,
                    'C1' ,
                    'Loc1' ,
                    'District1' ,
                    2000
          UNION ALL
          SELECT    '0003' ,
                    'C' ,
                    'C2' ,
                    'Loc2' ,
                    'District1' ,
                    3000
          UNION ALL
          SELECT    '0004' ,
                    'D' ,
                    'C2' ,
                    'Loc2' ,
                    'District1' ,
                    4000
          UNION ALL
          SELECT    '0005' ,
                    'E' ,
                    'C3' ,
                    'Loc2' ,
                    'District1' ,
                    5000
        ) a
GROUP BY ROLLUP(a.Cluster, a.BranchName) ,
        a.District;

这是我的结果

Loc Value
A   1000
B   2000
C1  3000
C   3000
D   4000
C2  7000
E   5000
C3  5000
District1   15000

我也想展示一下位置。像这样：

Loc Value
A   1000
B   2000
C1  3000
Loc1    3000
C   3000
D   4000
C2  7000
E   5000
C3  5000
Loc2    12000
District1   15000

使用Union ALL

你能详细说明如何根据样本数据确定预期结果吗？@Rhys我认为这很简单。

   SELECT BranchName, Value FROM
   (
        SELECT * FROM table
   ) A
   UNION ALL
   SELECT Location, SUM(Value) FROM
   (
        SELECT * FROM table
   ) A GROUP BY Location
   UNION ALL
   SELECT Cluster, SUM(Value) FROM
   (
        SELECT * FROM table
   ) A GROUP BY Cluster
   UNION ALL
   SELECT District, SUM(Value) FROM
   (
        SELECT * FROM table
   ) A GROUP BY District

declare @tbl as table (Branch varchar(max), 
                        BranchName varchar(max),
                        Cluster varchar(max),
                        Location varchar(max),
                        District varchar(max),
                        Value int)

INSERT INTO @tbl

select '0004' ,'D','C2','Loc2', 'District1' ,4000 UNION ALL

;with cte as (SELECT case when BranchName is null and cluster is not null then Cluster

, Cluster, Location, District,  sum(Value) Value FROM @tbl
group by
    grouping sets (

        (Location, District),
        (Cluster,Location, District),
        (BranchName, Cluster, Location, District),
        (Value)))

select Loc, value from cte where Loc is not null
