SemanticException Column xx Found in more than One Tables/Subqueries

执行hiveql时报错：

SemanticException Column xx Found in more than One Tables/Subqueries

Hive中有两张表中拥有同一个字段名称，在这两个表做关联的时候会报这个错误

将其中一个表的重复字段加上别名，然后进行关联查询

select city.city, hotel.hotel, hotel.hotelname from city city, 

(select city as hcity  ,hotel , hotelname from hotel) hotel

where city.city = hotel.hcity
