条件为 SQL 服务器的子查询

Question

我想在SQL服务器中寻求一点帮助。

我需要对客户购买的东西进行总计 $。

我的子查询只对整个 table 求和，但我需要类似

的东西

Numero D               TotalItem    TotalBOUGHT
-----------------------------------------------
111                     800           1200
111                     200           1200
111                     100           1200
111                     100           1200
455                     200            300
455                     100            300

这是我的代码

SELECT
    NumeroD, Descrip AS ClientName, CodClie AS ID, 
    Descrip1 AS Description,  TotalItem, CodUbic, 
    Día_Transaccion AS Day, Mes AS Month, ANO AS YEAR, 
    (SELECT SUM(TotalItem) FROM FORMULAFINAL) AS TotalAmount
FROM 
    FORMULAFINAL 
WHERE 
    Descrip LIKE 'Hector%' 
GROUP BY 
    TotalItem, NumeroD, Descrip, CodClie, Descrip1, 
    TotalItem, CodUbic, Día_Transaccion, Mes, Ano
ORDER BY 
    Ano DESC, NumeroD, Descrip, Descrip1, CodClie, TotalItem, 
    CodUbic, Día_Transaccion, Mes

enter image description here

Answer 1

也许使用像下面这样的窗口函数

select  
NumeroD, Descrip AS ClientName, CodClie AS ID, Descrip1 AS Description,  TotalItem, CodUbic, Día_Transaccion AS Day, Mes AS Month, ANO AS YEAR, 
    SUM(TotalItem) OVER (partition by NumeroD, DAY, MONTH, YEAR ) AS TotalAmount
    FROM FORMULAFINAL 
    WHERE Descrip LIKE 'Hector%' 
ORDER BY Ano DESC, NumeroD, Descrip, Descrip1, CodClie, TotalItem, CodUbic, Día_Transaccion, Mes
