Duplicate column names in SQL query

问题

How do I avoid a dup column name error in MySQL when creating a VIEW on two tables that both have the same column name as shown here

CREATE VIEW db.VI_RegionCity AS SELECT
    Region.Name,
    City.Name
FROM
    db.Region Region,
    db.City City
WHERE
    Region.RegionCode = City.RegionCode



ERROR: Duplicate column name 'Name'

回答1:

Using alias for column name

CREATE VIEW db.VI_RegionCity AS SELECT
    Region.Name as Region_name,
    City.Name as City_name
...//rest of the query

回答2:

CREATE VIEW db.VI_RegionCity AS SELECT
    Region.Name AS RegionName,
    City.Name AS CityName
FROM
    db.Region Region,
    db.City City
WHERE
    Region.RegionCode = City.RegionCode
