数据透视表SQL中的水平总计

Question

我有此查询工作：

      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;

该查询返回：

      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

我想在水平总计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？我已经读过一些东西UNION。

Answer 1

首先，您不需要事先对数据进行分组：PIVOT子句将为您完成此操作。因此，您可以删除GROUP BY子句并相应地SUM()在PIVOT中更改的参数：

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;

要添加总计列，可以使用如下所示的窗口 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;

但是请注意，如果您sourcetable包含的行的cap_idEmpresa值不同于PIVOT子句中列出的cap_valorfatura值，则也会将相应的值相加。因此，您可能需要sourcetable在透视之前过滤行集，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;
