如何在SQLite中计算小计列的总计

问题描述

我正在尝试使用C＃获取摘要报告。我已使用sqlite数据库存储数据。 在给定的图像中，我计算了每个位置的总价。请帮助我找出最后一行中的TotalPrice列的总计，如图所示。谢谢。 Please check image

这是我的查询。

  SELECT Job_Mst.JobCode,Location_Mst.LocationName,sum(JobTransaction.TransactionPrice) AS TotalPrice
FROM Job_Mst
LEFT JOIN JobTransaction ON Job_Mst.JobId = JobTransaction.JobId
LEFT JOIN Location_Mst ON Location_Mst.LocationId = Job_Mst.LocationId
WHERE JobTransaction.DATE BETWEEN @firstDate
        AND @secondDate
GROUP BY Job_Mst.LocationId

I am fetching data from 3 tables.. 

解决方法

检查一次

WITH Totals
AS (
    SELECT Job_Mst.JobCode,Location_Mst.LocationName,sum(JobTransaction.TransactionPrice) AS TotalPrice
    FROM Job_Mst
    LEFT JOIN JobTransaction ON Job_Mst.JobId = JobTransaction.JobId
    LEFT JOIN Location_Mst ON Location_Mst.LocationId = Job_Mst.LocationId
    WHERE JobTransaction.DATE BETWEEN @firstDate
            AND @secondDate
    GROUP BY Job_Mst.LocationId
    )
SELECT *
FROM Totals

UNION ALL

SELECT 'Total','',SUM(TotalPrice)
FROM Totals
