Question

Using the country and countrylanguage tables, write the SQL SELECT statement to display the countries and the languages that are spoken for each country. The languages are in the countrylanguage table. The countries are in the country table. Both tables have a "country code" column.

Use a column alias "Country" for the name of the country (the column name is "Name"). Order ascending by the name of the country, then the language.

Answer 1

The student's question was about writing an SQL query to list countries and their spoken languages using tables with a common 'country code'. The correct approach involves using a SELECT statement with a JOIN clause and an ORDER BY clause.

Step-by-step explanation:

The student is asking for help with writing an SQL SELECT statement to retrieve data from two different tables in a database. To obtain the desired output, one must perform a JOIN operation on the 'country' and 'countrylanguage' tables using the 'country code' column that is present in both tables.

The task is to display a list of countries along with the languages spoken in each, with the name of the country labeled as 'Country' and the results ordered by the country name and then by the language. Below is an example of how this SQL query could look:

SELECT c.Name AS 'Country', cl.Language
FROM country AS c
JOIN countrylanguage AS cl ON c.Code = cl.CountryCode
ORDER BY c.Name, cl.Language;

This query uses an inner join to combine rows from 'country' and 'countrylanguage' where the 'country code' matches. It then specifies the order of the output to first list by the country name in ascending order, followed by the language name in ascending order as well.
