Question

我正在尝试从2个表中提取数据：

•DolfinRMSCum.dbo.tSupplier
•DolfinRMSCum.dbo.tSupplierType

两个列都有一个公共字段和值<script src="https://cdnjs.cloudflare.com/ajax/libs/ramda/0.26.1/ramda.min.js"></script>，因此Join 但是我想在查询中查看SupplierTypeCode中的Description列值

DolfinRMSCum.dbo.tSupplierType

收到以下错误：

Msg 4104，第16级，状态1，第17行
不能绑定多部分标识符“ DolfinRMSCum.dbo.tSupplier.SupplierTypeCode”。

我尝试在Join中使用别名，但没有成功，如下所示：

> Select                Supplier.SupplierNumber as [Dolfin Code]
>                      ,Supplier.SagesupplierCode as [Sage Code]
>                      ,Supplier.SupplierName as Name
>                      ,Supplier.PrimaryTel as Tel
>                      ,Supplier.PrimaryFax as Fax
>                      ,Supplier.PrimaryContact as Contact
>                      ,Supplier.SupplierTypeCode  as [Supplier Type] 
>                      ,DolfinRMSCum.dbo.tSupplierType.Description as [Type Description]

Answer 1

DolfinRMSCum.dbo.tSupplierType在FROM子句中使用了两次。可以说一次就足够了。另外，如果您要应用表别名，那么也可以在SELECT语句中使用相同的别名。

您可以尝试以下查询吗？

SELECT              
 Supplier.SupplierNumber as [Dolfin Code]
 ,Supplier.SagesupplierCode as [Sage Code]
 ,Supplier.SupplierName as Name
 ,Supplier.PrimaryTel as Tel
 ,Supplier.PrimaryFax as Fax
 ,Supplier.PrimaryContact as Contact
 ,Supplier.SupplierTypeCode  as [Supplier Type] 
 ,SupplierType.Description as [Type Description]
 ,Supplier.Add1 as [Add 1]
 ,Supplier.Add2 as [Add 2]
 ,Supplier.Add3 as [Add 3]
 ,Supplier.Add4 as [Add 4]
 ,Supplier.CountryCode as Country
 ,Supplier.CurrencyCode as Currency
FROM DolfinRMSCum.dbo.tSupplier AS Supplier
FULL OUTER JOIN DolfinRMSCum.dbo.tSupplierType AS SupplierType ON SupplierType.SupplierTypeCode = Supplier.SupplierTypeCode
WHERE Deactivated = 0

多部分标识符“列名”无法绑定的问题
