Question

包含已完成订单的每位客户的全名，送货地址，帐单邮寄地址和应付款总额的视图。列出每个客户的个人订单

=＆GT;

go
create view employ as

        select employee.BusinessEntityID,
           firstname + ' ' +isnull( middlename + ' ','') +lastname as 'fullname',
           shippingaddress, billingaddress, totaldue, customer, individualorder    
        from AdventureWorks2012.HumanResources.Employee
   inner join AdventureWorks2012.person.person on employee.businessentityid = person.businessentityid
   inner join AdventureWorks2012.person.Address on employee.businessentityid = Address.AddressID
   inner join AdventureWorks2012.sales.SalesOrderDetail on employee.businessentityid = SalesOrderDetail.SalesOrderID
   inner join AdventureWorks2012.sales.Customer on employee.businessentityid = customer.CustomerID
GO

-- Now select from the view
Select * From employ

注意：我已经编辑了我的查询，但仍然收到了有关送货地址，帐单地址，应付总额和客户的无效列。我是否需要客户专栏？有人可以通过添加或删除我的查询不必要的内容进行更新，以便更正。所以我理解逻辑。

根据您的上述解释，我相信您可以通过以下方式解决此问题：

如果要查询视图，请先创建它，然后再Select * From employ

    create view employ as

        select employee.BusinessEntityID,
           firstname + ' ' +isnull( middlename + ' ','') +lastname as 'fullname',
           shippingaddress, billingaddress, totaldue, customer, individualorder    
        from AdventureWorks2012.HumanResources.Employee
        inner join AdventureWorks2012.person.person 
                   on employee.businessentityid = person.businessentityid

GO

-- Now select from the view
Select * From employ
