内部联接在其重复行上增加值

Question

已更新 我有3个这样的表：

[dbo].[CHEQUES]:
|Cla_Pdv    |    Che    |    Fecha    |    Tur    |
---------------------------------------------------       
|   FUEM    |    4423   |2016-01-01   |     2     |
--------------------------------------------------- 

[dbo].[CAPMO]:
|Clave_Pdv    |    Che    |    Com    |    Pla    |    Descripcion    |    Precio    |    Can    |
--------------------------------------------------------------------------------------------------------     
|   FUEM      |     4423  |      1    |    184    |    POZ            |    85        |    1    |
------------------------------------------------------------------------------------------------------
|   FUEM      |     4423  |      2    |    184    |    POZ            |    85        |    1    |
------------------------------------------------------------------------------------------------------
|   FUEM      |     4423  |      3    |    184    |    POZ            |    84        |    1    |
------------------------------------------------------------------------------------------------------

[dbo].[TURNO]:
|Clave_Pdv    |    Tur    |    Descripcion    |
-----------------------------------------------     
|   FUEM      |     1     |      DESAYUNOS    |
-----------------------------------------------
|   FUEM      |     2     |      COMIDAS      |
-----------------------------------------------
|   FUEM      |     3     |      CENAS        |
-----------------------------------------------

我需要[dbo]。[Capmo]表的每个值，但我想增加第一行的数量，因为两行在'Pla'gettting列上具有相同的值，并输出如下：

|  Cheque  |  Turno    |  Clave_Pdv  |  Pla  |  Descripcion  |  Precio  |  Cantidad  |
|   4423   |  COMIDAS  |    FUEM     |  184  |       POZ     |    85    |      2     |
|   4423   |  COMIDAS  |    FUEM     |  184  |       POZ     |    84    |      1     |

Answer 1

您似乎不需要Cheques和Capmo之间的联接，因为您的输出可以从Capmo获得。但是，您在评论中提到了其他表格，可能希望扩展您的问题以包含完整的示例。

数据

SELECT * INTO Cheques FROM (
  VALUES('FUEM', 4423, '2016-01-01', 2)) A (Cla_Pdv, Che, Fecha, Tur)


SELECT * INTO Capmo FROM (
  VALUES
  ('FUEM', 4423, 1, 184, 'POZ', 85, 1)
  ,('FUEM', 4423, 2, 184, 'POZ', 85, 1)
  ,('FUEM', 4423, 3, 184, 'POZ', 84, 1)
  ) A (Clave_pdv, Che, Com, Pla, Descripcion, Precio, Can)

SELECT * INTO Turno FROM (
  VALUES
  ('FUEM', 1,'DESAYUNOS')
  ,('FUEM', 2,'COMIDAS')
  ,('FUEM', 3,'CENAS')
  ) A (Clave_pdv, Tur,Descripcion)

查询

SELECT DISTINCT
    Cheques.Che Cheque
    ,Turno.Descripcion Turno
   ,Capmo.Clave_Pdv
   ,Capmo.Pla
   ,Capmo.Descripcion
   ,Capmo.Precio
   ,SUM(Capmo.Can) OVER ( PARTITION BY Capmo.Precio ) Cantidad
FROM
    Capmo
    JOIN Cheques ON Capmo.Clave_pdv = Cheques.Cla_pdv
    JOIN Turno ON Capmo.Clave_pdv = Turno.Clave_pdv AND Cheques.Tur = Turno.Tur
    ORDER BY Precio DESC;

Cheque      Turno     Clave_Pdv Pla         Descripcion Precio      Cantidad
----------- --------- --------- ----------- ----------- ----------- -----------
4423        COMIDAS   FUEM      184         POZ         85          2
4423        COMIDAS   FUEM      184         POZ         84          1
