SQL - 列名无效，但存在

Question

尝试使用内部联接时出现错误。

列名“供应商 ID”无效。

该列存在于两个表中。

select p.ProductID, s.CompanyName, od.orderID
from OPENROWSET('SQLOLEDB', 'Server=DESKTOP-509LB9L\MSSQLSERVER01;Trusted_Connection=yes;',
   'select ss.CompanyName from northwind.dbo.suppliers ss') s
   inner join [DESKTOP-509LB9L\MSSQLSERVER01].northwind.dbo.products p
on s.SupplierID = p.SupplierID
    inner join northwind.dbo.[Order Details] od
on od.ProductID = p.ProductID
    inner join northwind.dbo.Orders o
on od.OrderID = o.OrderID

Answer 1

您需要 select SupplierID 在OPENROWSET 。 如果您在未选择列的情况下连接两个表，这就是您收到错误的原因。

只需添加ss.SupplierID和ss.CompanyName如下

select ss.SupplierID, ss.CompanyName from northwind.dbo.suppliers ss

Answer 2

您必须 select 子查询中的相应列供应商ID，

select p.ProductID, s.CompanyName, od.orderID
from OPENROWSET('SQLOLEDB', 'Server=DESKTOP- 
509LB9L\MSSQLSERVER01;Trusted_Connection=yes;',
'select ss.CompanyName, SS.SupplierID from northwind.dbo.suppliers ss') s
inner join [DESKTOP-509LB9L\MSSQLSERVER01].northwind.dbo.products p
on s.SupplierID = p.SupplierID
inner join northwind.dbo.[Order Details] od
on od.ProductID = p.ProductID
inner join northwind.dbo.Orders o
on od.OrderID = o.OrderID
