数据透视表SQL中的水平总计

Question

我有这个查询工作：

      select cap_idPlanoContasFin  , [3684],[2234],[2] ,  
      from 
      (
      select cap_idPlanoContasFin,cap_idempresa,sum(cap_valorfatura) 
          as Stotal    
          from erp_ContasPagar 
       group by cap_idPlanoContasFin , cap_idEmpresa 

       ) as sourcetable
       pivot 
       (sum(Stotal)for cap_idEmpresa in ([3684],[2234],[2])
       )as pivottable;

此查询返回：

      cap_idPlanoContasFin  3684          2234       2
                      3 9000          NULL      NULL
                     10 1057840,68    NULL  1865081,35
                     11 NULL          7283,1    591,9
                     12 NULL          NULL  178914,45
                     13 9305,07       1117,6    500
                     14 NULL          59333,5   34611,74

我想在水平总示例中输入相同的查询：

      cap_idPlanoContasFin  3684      2234            2           Total
      ---------------------------------------------------------------------      
                       13   9305,07    1117,6   500          10922,67

怎么做到这个？ 我用UNION读过一些东西。

Answer 1

首先，您不需要事先对数据进行分组：PIVOT子句将为您执行此操作。 因此，您可以删除GROUP BY子句并相应地更改PIVOT中的SUM()参数：

select cap_idPlanoContasFin, [3684], [2234], [2]  
from 
(
  select cap_idPlanoContasFin, cap_idempresa, cap_valorfatura
    from erp_ContasPagar 
  group by cap_idPlanoContasFin , cap_idEmpresa
) as sourcetable
pivot 
(
  sum(cap_valorfatura) for cap_idEmpresa in ([3684], [2234], [2])
) as pivottable;

要添加总列，可以使用如下窗口 SUM() ：

select cap_idPlanoContasFin, [3684], [2234], [2], Total
from 
(
  select cap_idPlanoContasFin, cap_idempresa, cap_valorfatura, sum(cap_valorfatura) over (partition by cap_idPlanoContasFin) as Total
    from erp_ContasPagar 
) as sourcetable
pivot 
(
  sum(cap_valorfatura) for cap_idEmpresa in ([3684], [2234], [2])
) as pivottable;

但请注意，如果您的sourcetable包含的cap_idEmpresa值不是PIVOT子句中列出的值，则相应的cap_valorfatura值也会相加。 因此，您可能希望在sourcetable之前过滤源表行集，如下所示：

select cap_idPlanoContasFin, [3684], [2234], [2], Total
from 
(
  select cap_idPlanoContasFin, cap_idempresa, cap_valorfatura,
         sum(cap_valorfatura) over (partition by cap_idPlanoContasFin) as Total
    from erp_ContasPagar 
   where cap_idempresa in (3684, 2234, 2)
) as sourcetable
pivot 
(
  sum(cap_valorfatura) for cap_idEmpresa in ([3684], [2234], [2])
) as pivottable;

Answer 2

谢谢大家，这是最后的查询：

 select cap_idPlanoContasFin, plc_classificador, plc_nomeConta,[3684], [2234], [2], 
 isnull ([2234],0) + isnull ([2],0) AS Subtotal ,Total    
 from 
 (
 select A.cap_idempresa, A.cap_idPlanoContasFin,  A.cap_valorfatura, 
 B.plc_classificador , B.plc_nomeConta,
 sum(A.cap_valorfatura) over (partition by A.cap_idPlanoContasFin) as Total
 from erp_ContasPagar A /*where cap_idempresa in (3684, 2234, 2)*/ 
 inner  join  tbl_PlanoFinanceiro B on A.cap_idPlanoContasFin = B.plc_id
 )  as sourcetable
 pivot 
 (
 sum(cap_valorfatura) for cap_idEmpresa in ([3684], [2234], [2])
 ) as pivottable;

我需要使用isnull来将NULL更改为su到sume小计。 再次感谢您的帮助
