I’m working with the InnoDB version of MySQL’s world database (available here) and am trying to fetch a list of the countries of South America and their capitals. In my mind, the query should look like this:

    SELECT `Country.Name` as `CountryName`, `City.Name` as `CityName`
    FROM `Country`, `City` 
    WHERE `Continent` = 'South America' AND `ID` = `Capital`;

But that one gives error #1054 - Unknown column 'Country.Name' in 'field list', even though the table Country does have the field Name.

Why isn’t MySQL finding the fields I want? How do I change the query to make it find them?

Let me know if I need to provide more information for you to be able to help me.

    If you quote identifiers, do not surround the inner dot with backticks.

    SELECT
  `Country`.`Name` AS CountryName,
  `City`.`Name` AS CityName

    If you quote around the inner dot, it will be assumed to be inside the column name, rather than a separator between the table name and column name — you have a column named Name, but not a column called Country.Name. In this case, however, it is unnecessary to quote any of the identifiers since none of them are MySQL reserved keywords.
