Question

我有一个大约25列的表格来表示位置，我想知道是否有任何方法可以将此结果转换为更清晰的布局？我在SQL中的内容是：

SELECT sum(isnull(p.[injuryFace],0)) AS [Face]
  ,sum(isnull(p.[InjuryHead],0)) AS [Head]
  ,sum(isnull(p.[InjuryEye],0)) AS [Eye]
  ,sum(isnull(p.[InjuryLeftFinger],0)) AS [Finger - Left]
  ,....
FROM tbl_OHS_IncidentsPeople P

这给了我一个类似于

的结果数据集

Face | Head | Eye | Finger - Left | .... |
---------------------------------------------
  0  |  1   |  2  |      0        | ...  |

我最终想要的是

Area          | Count |
------------------------
Face          |   0   |
Head          |   2   |
Eye           |   3   |
Finger - Left |   0   |

不，我看了Simple way to transpose columns and rows in Sql?似乎有我需要的东西，但我似乎无法理解它在我脑海里，因为我不想转置整个表

任何帮助都会很棒

一种方法是通过以下工会分割计数：

select 'Face' as area, sum(isnull(p. [ injuryFace ], 0)) as location
  from tbl_OHS_IncidentsPeople P
union all
select 'Head' as area, sum(isnull(p. [ InjuryHead ], 0))
  from tbl_OHS_IncidentsPeople P
union all
select 'Eye' as area, sum(isnull(p. [ InjuryEye ], 0))
  from tbl_OHS_IncidentsPeople P
union all
select 'Finger - Left' as area, sum(isnull(p. [ InjuryLeftFinger ], 0))
  from tbl_OHS_IncidentsPeople P

转置SQL结果
