mysql - MySQL 3 Table Union 并运行一列的 SUM

Question

这是我正在尝试创建的表组件的示例。

这是我目前正在尝试的查询（不成功）。这三个表是 wp_ko、rack 和 bt_runin。我遇到的问题是标有“结果”的列的 SUM。我希望“结果”列显示“体积”列中加减法的余额。

SELECT StartTime, name, Lot, fv, koVol/31 AS Volume, SUM(koVol/31) AS Result
FROM wp_ko
WHERE fv = 11 AND name = "SEZI" AND lot LIKE "1007%"
UNION
SELECT StartTime, destName, destLot, dest, TotVol, SUM(TotVol)
FROM rack
WHERE dest = 11 AND destname = "SEZI" AND destlot LIKE "1007%"
UNION
SELECT StartTime, srcName, srcLot, Source, TotVol*-1, SUM(TotVol*-1)
FROM rack
WHERE Source = 11 AND srcName = "SEZI" AND srcLot LIKE "1007%"
UNION
SELECT StartTime, Name, Lot, fv, Total_Bls*-1, Total_Bls*-1)
FROM bt_runin
WHERE fv = 11 AND Name = "SEZI" AND Lot LIKE "1007%"

这是我得到的结果表。

在朋友的帮助下，我能够弄清楚这一点。下面是有效的查询，下面是结果表的图片。

SELECT q1.StartTime AS "Start Time", 
    q1.ProductCode as "Product Code",
q1.Lot AS "Lot",
q1.FV AS "FV",

q1.Source AS "Source"
