Question

我是SQL Server的新手，我正在尝试创建一个包含所有客户信息的视图。

如果客户存在，Customer是我想要在所有其他表中引入的主表。

我尝试使用SQL Server Management Studio，但它没有给我带来任何结果。

这就是我选择的表格：

enter image description here

我希望Corporation中的分支和AccountNumber中的Account以及其他表中的所有其他列。

这就是管理工作室给我的：

SELECT     
   Customer.Customer.*, Customer.Miscellaneous2.*, Common.Address.*, 
   Company.CorporationStructure.Branch AS Expr1, Customer.Delivery.*, 
   Customer.Miscellaneous.*, Customer.Account.AccountNumber AS Expr2 
FROM         
   Customer.Account 
INNER JOIN
   Common.Address ON Customer.Account.AccountId = Common.Address.ForeignId 
INNER JOIN
   Company.CorporationStructure ON Customer.Account.CorporationStructureId = Company.CorporationStructure.CorporationStructureId 
                       AND Customer.Account.CorporationStructureId = Company.CorporationStructure.CorporationStructureId 
 INNER JOIN
    Customer.Customer ON Company.CorporationStructure.Branch = Customer.Customer.Branch 
 INNER JOIN
    Customer.Delivery ON Company.CorporationStructure.Branch = Customer.Delivery.Branch 
 INNER JOIN
    Customer.Miscellaneous ON Company.CorporationStructure.Branch = Customer.Miscellaneous.Branch 
 INNER JOIN
    Customer.Miscellaneous2 ON Company.CorporationStructure.Branch = Customer.Miscellaneous2.Branch

返回零结果。

任何人都能看到我做错了什么？

我按照建议更新了查询：

                      Customer.Miscellaneous2 ON Company.CorporationStructure.Branch = Customer.Miscellaneous2.Branch

现在我得到了一个结果，但现在我一遍又一遍地接待同一个客户：

Answer 1

原因可能是因为公司结构的双重加入。问题在于：

INNER JOIN
    Customer.Customer ON Company.CorporationStructure.Branch = Customer.Customer.Branch 
 INNER JOIN
    Customer.Delivery ON Company.CorporationStructure.Branch = Customer.Delivery.Branch

您需要在from子句中出现两次CorporateStructure，一次针对客户，一次针对交付。

SQL Server视图未获得任何结果
