Joining Data with SQL

Here you can access every table used in the course. To access each table, you will need to specify the world schema in your queries (e.g., world.countries for the countries table, and world.languages for the languages table).


Note: When using sample integrations such as those that contain course data, you have read-only access. You can run queries, but cannot make any changes such as adding, deleting, or modifying the data (e.g., creating tables, views, etc.).

Start with your inner join in line 5; join the tables countries AS c (left) with economies (right), aliasing economies AS e. Next, use code as your joining field in line 7; do not use the USING command here. Lastly, select the following columns in order in line 2: code from the countries table (aliased as country_code), name, year, and inflation_rate.
