Select * on inner join with common columns
You need to specify every column by your self.

Example : Table Country and City both have a name column

SELECT 
    a.Name AS CountryNane, b.Name AS CityName, c.*
FROM
    Country a
        JOIN
    City b ON a.Code = b.CountryCode
        JOIN
    CountryLanguage c ON a.Code = c.CountryCode;
