我怎样才能从这个数据库中得到一个人的国家？

Question

我正在用一个给定的数据库，一个假的模拟器在Mysql上进行任务，真的很不好。我的问题是，我需要一个查询来获取客户国家的数据，但客户的表只包含一个城市数据。表是：

tbl_Client: 
/ID* 
/Name 
/Birthday 
/ID_City (FK) 

tbl_City: 
/ID_City * 
/vchCityName 
/ID_State (FK) 

tbl_State: 
/ID_State * 
/vchStateName 
/ID_intRegion (FK) 

tbl_Region: 
/ID_Region * 
/vchRegionName 
/ID_Country (FK) 

tbl_Country: 
/ID_Country * 
/vchCountryName 

所以，我的问题是，我怎么能得到客户的国家与其他数据进行比较？ （最大的问题是将客户的国籍与他们喜欢的音乐家进行比较，但我似乎无法管理的是客户端部分）。我正在尝试一些非常基本的东西，但它不起作用。

(...)tbl_Client CL, tbl_City CT, tbl_State ST, tbl_Region R, tbl_Country C 
WHERE CT.ID_City = ST.ID_City 
AND ST.ID_Region = R.ID_Region 
AND R.ID_Contry = C.ID_Contry 

然后我试着来比较C.ID_Country，和好了，我尝试了很多的东西，而且还得到了什么......我真的很感激，如果有人能够告诉我这一点。

非常感谢大家！

有了这个，你得到的所有数据相对于

select tbl_Client.*, tbl_City.*, tbl_State.*, tbl_Region.*, tbl_Country.* 
from tbl_Client 
inner join tbl_City on tbl_Client.ID_City = tbl_City.ID_City 
inner join tbl_State on tbl_State.ID_State = tbl_City.ID_State 
INNER join tbl_Region on tbl_Region.ID_Region = tbl_State.ID_Region 
INNER join tbl_Country on tbl_Country.ID_Country =tbl_Region.ID_Country; 

，如果你需要的国家为客户ID例如ID = 3

select tbl_Client.* , tbl_Country.* 
from tbl_Client 
inner join tbl_City on tbl_Client.ID_City = tbl_City.ID_City 
inner join tbl_State on tbl_State.ID_State = tbl_City.ID_State 
INNER join tbl_Region on tbl_Region.ID_Region = tbl_State.ID_Region 
INNER join tbl_Country on tbl_Country.ID_Country =tbl_Region.ID_Country 
where tbl_Client.ID = 3;
