SQL 服务器 : join tables causes the data to duplicate on every row

Question

我有一个返回一些冗余数据的查询。有人可以帮我更正这个查询吗？我也附上了表格关系。

SELECT
   dbo.supplierOrder.sectionID,
   dbo.supplierOrder.supplierID,
   dbo.supplierOrder.supplierOrderNo,
   dbo.supplierOrder.supplierOrderCreated,
   dbo.supplierOrder.supplierOrderConfirmStatus,
   dbo.supplierOrderDetails.productID,
   dbo.supplierOrderDetails.orderQty,
   dbo.supplierOrderReceive.invoiceno,
   dbo.supplierOrderReceive.supplierInvoiceno,
   dbo.supplierOrderReceive.ID,
   dbo.supplierOrderReceiveDetail.qtyArrived
FROM
   dbo.supplierOrder
INNER JOIN
   dbo.supplierOrderDetails ON (dbo.supplierOrderDetails.supplierOrderID = dbo.supplierOrder.ID)
INNER JOIN 
    dbo.supplierOrderReceive ON (dbo.supplierOrderReceive.supplierOrderID = dbo.supplierOrder.ID)
INNER JOIN 
    dbo.supplierOrderReceiveDetail ON (dbo.supplierOrderReceiveDetail.supplierOrderReceiveID = dbo.supplierOrderReceive.ID)       
WHERE
   dbo.supplierOrder.ID = 1 ; 

这是我得到的输出

这不是我想要的。最后一列 qtyArrived 应该只显示它​​的相关数量，但在这里你可以看到它对每个 productID 重复

这是数据库表和关系

Answer 1

我认为最后一张表还应该使用 ProductId 连接，而不仅仅是 OrderID :

LEFT JOIN 
    dbo.supplierOrderReceiveDetail
ON  
(dbo.supplierOrderReceiveDetail.supplierOrderReceiveID=dbo.supplierOrderReceive.ID)
AND 
(dbo.supplierOrderReceiveDetail.ProductID =dbo.sdbo.supplierOrderDetails.ProductID)
