sql - MS Access 查询中的语法错误？

Question

我将 7 列合并为一列，即所有地址都合并为一列。最初，位置、城市、州和国家存储其显示值代码在相应的表中。所以我加入了下面这个查询中的所有内容。

SELECT CustomerName, CustomerId, ContactPerson, 

((BFlatNo +','+ BPremises +','+ BStreet +','+ BArea) + ',' +
(select LocationName from Location where LocationId = Customer.Location) + ',' +
(select CityName from City where CityId = Customer.City) + ',' +
(select StateName from State where StateId = Customer.State) + ',' +
(select CountryName from Country where CountryId = Customer.Country) + ',' + 
(BMobileNumber) ) AS BillingAddress, 

((DFlatNo +','+ DPremises +','+ DStreet +','+ DArea) + ',' +
 (select LocationName from Location where LocationId = Customer.Location) + ',' +
 (select CityName from City where CityId = Customer.City) + ',' +
 (select StateName from State where StateId = Customer.State) + ',' +
 (select CountryName from Country where CountryId = Customer.Country) + ',' + 
(DPhone) ) AS DeliveryAddress

FROM Customer
WHERE Customer.CustomerId = 11;

在 MS Access 中预览数据 TableView 时，它要求提供 Customer.Location、Customer.City、Customer.State 和 Customer .Country 然后显示 CustomerId=11 的结果

当我单击“数据 TableView ”时，我需要显示客户详细信息。 实际上，在客户表位置中，其字段名称是 BLocation，城市是 BCity，州是 BState，国家是 BCountry，但如果我给出 Select LocationName from Location where LocationId=Customer.BLocation 它显示语法错误。

帮我解决这个问题？
