嘿那里我正在寻找基于下表的具体输出

数据库表

╔══════════════════════════════════════════════════════════════════════╗
║ Department  Division      Name   Level1    Level2  Level3 GrandTotal ║
╠══════════════════════════════════════════════════════════════════════╣
║ Insurance   Distribution  John                1               3      ║
║ Insurance   Distribution  Mark     1                          3      ║
║ Insurance   Distribution  Joe      1                          3      ║
║ Marketing   Distribution  Rob                         1       2      ║
║ Marketing   Distribution  Sam      1                          2      ║

╚══════════════════════════════════════════════════════════════════════╝

我正在寻找的输出是

╔═════════════════════════════════════════════════════════════════════════════╗
║     Department  Division     Name     Level1  Level2     Level3  GrandTotal ║
╠═════════════════════════════════════════════════════════════════════════════╣
║     Insurance   Distributon                                           3     ║
║                              John               1                     1     ║
║                              Mark        1                            1     ║
║                              Joe         1                            1     ║

║                              Sam         1                            1     ║
║     Claims     Solution                                               3     ║
║                              Bob         1                            1     ║
║                              Tom         1                            1     ║
║                              Gin                            1         1     ║
╚═════════════════════════════════════════════════════════════════════════════╝

首先，如果有这种类型的表输出的名称，我会道歉，因为我不知道它并且会使标题更好。我有一个想法是使用游标遍历每一行，并将部门和部门存储在一个变量中，并在每次检查时检查它们是否相同，如果是这样，那么部门和部门会一直空白，直到它们发生变化。但我希望有一个更简单的方法来做到这一点。任何帮助将不胜感激。

就像@SQLPolice所说，你可以用汇总做这样的事情，但我不能真的推荐它。它变得混乱，难以维护。这应该在数据库之外完成：

select 
  case when grouping(name) = 1 then department end as department, 
  case when grouping(name) = 1 then division end as division, 
  name,
  case when grouping(name) = 0 then sum(isnull(level1,0)) end as level1,
  case when grouping(name) = 0 then sum(isnull(level2,0)) end as level2,
  case when grouping(name) = 0 then sum(isnull(level3,0)) end as level3,
  case when grouping(name) = 1 then sum(isnull(level1,0)) + sum(isnull(level2,0)) + sum(isnull(level3,0)) end as GrandTotal
from 
  table1
group by
  department, 
  division, 
  rollup(name)
order by
  table1.department,
  table1.division,
  grouping(name) desc

我的假设是，总计实际上应该是行的总计，并且仅在摘要级别上显示，而不是全部显示，并且实际上并不存在于数据中。

这里的技巧是分组（字段），它告诉行是详细行还是摘要行，汇总在更高级别创建摘要。

这是SQL Fiddle可以玩的。
