我正在尝试获取客户发票的总价。我有intMaterialQuantity * monMaterialCost给我材料的总成本。然后我需要通过乘以intHoursWorked * monHourlyRate来获得人工成本。然后我需要将这两个总数加在一起并增加35％的利润。我需要这个作为monCustomerInvoice出现在每份工作中。
SELECT
TJ.intJobID
,TJS.strJobStatus
,SUM ((TJM.intMaterialQuantity * TM.monMaterialCost)+(TJE.intHoursWorked * TE.monHourlyRate))(1.35) AS monCustomerInvoice
FROM
TJobs AS TJ
,TJobMaterials AS TJM
,TMaterials AS TM
,TJobStatus AS TJS
,TJobEmployees AS TJE
,TEmployees AS TE
WHERE
TJM.intJobID = TJ.intJobID
AND TJM.intMaterialID = TM.intMaterialID
AND TJ.intJobStatusID = TJS.intJobStatusID
AND TE.intEmployeeID = TJE.intEmployeeID
AND TJE.intJobID = TJ.intJobID
AND TJ.intJobStatusID = 3
GROUP BY
TJ.intJobID
,TJS.strJobStatus
这就是我得到的
intJobID strJobStatus monCustomerInvoice
----------- ------------------------ ------------------------
1 Complete 13014.8500
3 Complete 2907.9500
4 Complete 1146.7800
8 Complete 15270.6700
9 Complete 10290.6700
这是我需要的输出
intJobID strJobStatus monCustomerInvoice
----------- ----------------- ------------------------
1 Complete 3,979.46
3 Complete 5,154.33
4 Complete 1,654.33
8 Complete 19,284.29
9 Complete 12,102.29
我无法弄清楚为什么它会给我如此大的总数。我知道这是旧的语法，但这是我需要提交的方式。谢谢！

<强>更新
该问题更新包括架构和数据是完美的，有很多帮助。
您应该尝试使用两个子查询，一个用于每个作业ID的材料成本，另一个用于每个作业ID的人工成本，而不是使用浓密的查询来尝试同时进行两次计算。
与yesterday类似，由于这些表的关联方式，此查询产生重复项存在问题。您必须找到重复项的来源以及错误过滤其他行的方式。
查看表模式并确定哪些列是唯一键，其他列需要另一种方法来获得1：1结果。
