我有三个表，vehicle_service_invoice，vehicle_service_labor，vehicle_service_parts。所有这些表都使用每个表上的invoice行相互关联。我想查看这三个名为vehicle_service的表，这些表将显示零件和人工连接到发票表时的总价格。
使用单个表格，我SUM和extended列GROUP BY invoice列vehicle_service_labor和vehicle_service_parts列vehicle date po invoice labor parts sublet total

。但是，如何将此信息连接回vehicle_service_invoice的发票栏，以便正确显示？
我希望它看起来像这样......

这些数据有点谨慎，因为它只是为了说明目的，只是为了向您展示我的意思，以及我正在谈论的数据类型。
答案 0 :(得分：2)
您可以使用子查询从其他表中获取总计。 为了能够将两个小计一起添加，请使用另一个子查询：
SELECT *, labor + parts AS total
FROM (SELECT unit AS vehicle,
date,
po,
invoice,
(SELECT TOTAL(extended)
FROM vehicle_service_labor
WHERE invoice = vehicle_service_invoice.invoice
) AS labor,
(SELECT TOTAL(extended)
FROM vehicle_service_parts
WHERE invoice = vehicle_service_invoice.invoice
) AS parts
FROM vehicle_service_invoice)
ORDER BY date,
invoice
