動態數據透視表SQL Server 2012中使用COUNT（）和SUM（）和Total列

Question

我想要做的（列的名稱是動態過去了，但我硬編碼，因此它似乎更簡單在這個問題上）：

我想查詢使用數據透視表數據庫來和一個字段和計數在SQL Server 2012中的表的行，但是，除此之外，我想檢索彙總到的COUNT（）和SUM（）函數。

通常情況下，數據透視表是這樣的（這是比什麼，我試圖達到簡單）：

declare @campos nvarchar (max) 
 
select @campos = coalesce(@campos + ',[' + Setor + ']', '[' + Setor + ']') 
 
from dbo.TbFinanciamentos 
 
group by Setor 
 
order by Setor 
 

 
declare @resultado nvarchar(max) 
 
set @resultado = 
 
     'select * from(select Setor, ''br-'' + lower(UF_FILIAL) as [hc-key] from dbo.TbFinanciamentos) a 
 
\t \t pivot(
 
\t \t  count(Setor) 
 
\t \t \t for Setor in(' + @campos + ') 
 
\t \t ) a' 
 

 
execute(@resultado)

但是，我想包括總（總計）作爲一列，比我跟着 this tutorial，一切都沒有問題。

我有什麼事這麼遠（這是工作）：

declare @campos nvarchar (max) 
 
select @campos = coalesce(@campos + ',[' + Setor + ']', '[' + Setor + ']') 
 
from dbo.TbFinanciamentos 
 
group by Setor 
 
order by Setor 
 

 
declare @total nvarchar(max) 
 
select @total = coalesce(@total + 'isnull([' + Setor + '], 0) + ', 'isnull([' + Setor + '], 0) + ') 
 
from dbo.TbFinanciamentos group by Setor order by Setor 
 
set @total = left(@total, len(@total) - 1) 
 

 
declare @resultado nvarchar(max) 
 
set @resultado = 
 
     'select *, '+ @total +' as [value] into #temp_total 
 
     from (select Setor, ''br-'' + lower(UF_FILIAL) as [hc-key] from dbo.TbFinanciamentos) a 
 
\t \t pivot(
 
\t \t  count(Setor) 
 
\t \t \t for Setor in(' + @campos + ') 
 
\t \t ) b 
 
     select * from #temp_total' 
 

 
execute(@resultado)

但是，正如我做了COUNT（），我想爲SUM（做），並都在檢索相同的查詢。

我試過到目前爲止做什麼，我的目標是：

1. 我複製樞紐部，並試圖做一個FULL OUTER JOIN，但問題是，它是重複的列到最後的結果是什麼產生一個錯誤（無效的列名稱）。當我打印@resultado時，它就是列正在複製。

declare @campos nvarchar (max) 
 
select @campos = coalesce(@campos + ',[' + Setor + ']', '[' + Setor + ']') 
 
from dbo.TbFinanciamentos 
 
group by Setor 
 
order by Setor 
 

 
declare @total nvarchar(max) 
 
select @total = coalesce(@total + 'isnull([' + Setor + '], 0) + ', 'isnull([' + Setor + '], 0) + ') 
 
from dbo.TbFinanciamentos group by Setor order by Setor 
 
set @total = left(@total, len(@total) - 1) 
 

 
declare @resultado nvarchar(max) 
 
set @resultado = 
 
     'select *, '+ @total +' as [value] into #temp_total 
 
     from (
 
\t \t  (select Setor, ''br-'' + lower(UF_FILIAL) as [hc-key] from dbo.TbFinanciamentos 
 
\t \t \t \t pivot(
 
\t \t \t \t \t count(Setor) 
 
\t \t \t \t \t for Setor in(' + @campos + ') 
 
\t \t \t \t ) as b 
 
\t \t \t ) as sth 
 
\t \t \t full outer join 
 
\t \t \t (
 
\t \t  select cast(Valor_do_Emprestimo as float) as Valor_do_Emprestimo, Setor, ''br-'' + lower(UF_FILIAL) as [hc-key] from dbo.TbFinanciamentos 
 
\t \t \t \t pivot(
 
\t \t \t \t \t count(Setor) 
 
\t \t \t \t \t for Setor in(' + @campos + ') 
 
\t \t \t \t ) as b 
 
\t \t \t ) as sth_else 
 
\t \t \t on sth.[hc-key] = sth_else.[hc-key] 
 
\t \t ) 
 
     select * from #temp_total' 
 

 
execute(@resultado)

我試圖UNPIVOT and PIVOT method產生無效列的誤差爲好。

所以不用說，做任何動態的事情都是很成問題的，因爲你從來沒有真正掌握過你的元數據。在任何情況下，當你有多個條件聚合這樣的凝聚使用CASE語句，你的東西不同的措施，如

SUM(CASE When Setor = ''' + Setor ''' then 1 else 0 end) 
as [' + Setor + '_Count], 
SUM(CASE When Setor = ''' + Setor ''' then Valor_do_Emprestimo else 0 end) 
as [' + Setor + '_Total],' 

，只是建立一個單一的查詢對您的數據集這樣它更易於接受。

總之，要回答你的具體問題，如果你想這兩個，你必須提供獨特的列名，這意味着你需要創建略有不同的版本@campos和@total的結合。在這裏，我剛剛完成了@campos給你的想法。

通知我也不得不hc_key改爲hc_key2在第二樞軸也避免了重複的列名。

declare @campos nvarchar (max) 
select @campos = coalesce(@campos + ',[' + Setor + ']', '[' + Setor + ']') 
from dbo.TbFinanciamentos 
group by Setor 
order by Setor 

declare @campos2 nvarchar (max) 
select @campos2 = coalesce(@campos2 + ',[' + Setor + '_2]', '[' + Setor + '_2]') 
from dbo.TbFinanciamentos 
group by Setor 
order by Setor 

declare @total nvarchar(max) 
select @total = coalesce(@total + 'isnull([' + Setor + '], 0) + ', 'isnull([' + Setor + '], 0) + ') 
from dbo.TbFinanciamentos group by Setor order by Setor 
set @total = left(@total, len(@total) - 1) 

declare @resultado nvarchar(max) 
set @resultado = 
     'select * into #temp_total from (
     select *, '+ @total +' as [value]   from 
     (
      select * from (select Setor, ''br-'' + lower(UF_FILIAL) as [hc-key] from dbo.TbFinanciamentos) pvt 
       pivot(
        count([Setor]) 
        for Setor in(' + @campos + ') 
       ) as b 
      ) as sth 
      full outer join 
      (
       select *   from (
      select * from (select cast(Valor_do_Emprestimo as float) as Valor_do_Emprestimo, Setor+''_2'' as Setor, ''br-'' + lower(UF_FILIAL) as [hc-key2] from dbo.TbFinanciamentos) pvt 
       pivot(
        sum([Valor_do_Emprestimo]) 
        for Setor in(' + @campos2 + ') 
       ) as b 
      ) c 
      ) as sth_else 
      on sth.[hc-key] = sth_else.[hc-key2] 
     ) d 

     select * from #temp_total' 
     execute(@resultado)
