Question

如何使用我创建的视图来获取不同的数据输出。我创建了视图VJobCustomerLaborCost。该视图为每个客户提供每项工作的总工资成本。我需要为每位客户提供每位客户的总人工成本。我已经给出了视图和示例输出。

GO
CREATE VIEW VJobCustomerLaborCost
AS
SELECT DISTINCT
     TJ.intJobID
    ,TJ.strJobDescription
    ,TC.intCustomerID
    ,TC.strLastName + ', ' + TC.strFirstName AS strCustomerName
    ,SUM(TJE.intHoursWorked * TE.monHourlyRate) AS monTotalLaborCost
FROM    
     TJobs          AS TJ
    ,TJobCustomers  AS TJC
    ,TCustomers     AS TC
    ,TJobEmployees  AS TJE
    ,TEmployees     AS TE
WHERE
        TJ.intJobID         =   TJC.intJobID
    AND TJC.intCustomerID   =   TC.intCustomerID
    AND TJ.intCustomerID    =   TJC.intCustomerID
    AND TJE.intJobID        =   TJ.intJobID
GROUP BY
     TJ.intJobID
    ,TJ.strJobDescription
    ,TC.intCustomerID
    ,TC.strLastName
    ,TC.strFirstName
GO

这是我视图的输出。这给了我所有客户和每个工作总劳动力成本

 intJobID      strJobDescription         intCustomerID       strCustomerName       monTotalLaborCost
----------- ------------------------- -------------------  -----------------    ---------------------

4           Bedroom Remodel                 4             Solo, Hans                2850.00

我需要的是使用创建的视图来获得每个客户的总人工成本。所以输出将是

   intCustomerID       strCustomerName       monTotalLaborCost
 -------------------  -----------------    ---------------------
    1               Belcher, Bob                37,430
    3               Parker, Peter               5,510
    4               Solo, Hans                  2,850
    2               Stark, Tony                 0.00

如何使用上述视图获取此输出？

Answer 1

看起来您只需要对数据进行分组和汇总：

select 
    intCustomerID, 
    strCustomerName, 
    sum(monTotalLaborCost) as monTotalLaborCost
from VJobCustomerLaborCost
group by intCustomerID, strCustomerName
